MultiModule xDSL Tester

Just received recently a new toy for my test nook playplace yesterday. And this time it is the Sunset XDSL tester version 1. Its quite a good gadget with a rugged and dark look. It has separate modules for different test platforms which makes it flexible. I remember the test tool I used before when i was working with Alcatel Abu Dhabi, the Wavetek. Its one hell of a test unit, so rugged and compact yet filled with so much features and capabilities in a testing environment.

Well got to play with this one, my Boss were expecting a report in a week. Its quite one good toy, i think. This will save us time in analyzing and isolating field problems. Ill give you my feedback regarding this unit next year. So just keep in touch and keep visiting me for updates on new gadgets and equipments i play with everyday.

Kristian's Test Nook

Just spend my whole day, packing up the wireless radio i tested for a week. These are to be brought back to their respective suppliers next week. Hmmm, but still my table is as topsy turvy as yesterday...test table as they said. Just played with a Veo Wireless Observer and a Protech broadband router a minute ago. And the Wireless IP Camera is definitely cool! You can remotely control its movement through the Internet or on a LAN. Tried to put it in the cafeteria and shoot some pictures of ladies heheheh eating there, while i am inside the server room. Also, played with it by shooting pictures on my little nook here in the office.

These are my console stations, a 512MB DDR,80GB SATA, 64MB GeForce, Pentium 4 2.8Ghz CPU and 17" Silver Black Monitor courtesy of Dataworld. And an old ECS laptop which i borrowed from my Boss. Another HP Brio is hidden below the table also for testing.

These are the recent toys I played with. A level one VPN/Broadband Routers, Zyxel Prestige modems, Airspan AP and SU IDU,BATM Telco gateways and Welltech FXO. Hopefully there are more to come, so ill enjoy more playing here in my little test nook.

For a view, this is my nook, at the right side of the server room. Not really a good place but the reason i was here coz the wireless radio are at the rooftop. And the cables are in the right side window.

You may notice the modems hanging in the picture..those were my christmas decorations. Hehehehe it blinks like christmas lights especially when the server room lights were turn off. And those cables are my christmas tree.....

Hardware Review: Level One FBR-1417TX

Home or small office VPN anyone????...before i will try to discuss these new box i have here in the table, you might want to check its key features first.

Key features:

* Integrates with 4 ports Fast Ethernet switch: 10/100Mbps MDI/MDIX auto-sensing
* Provides 10/100Mps WAN interface to connect with DSL or cable modem for broadband Internet access
* Built-in one parallel port and one USB port for printer connection
* Browser-based interface configuration and management: OS independent, easy-to-use for consumer install
* Supports VPN server of IPSec, L2TP and PPTP
* Built-in NAT function: allow multiple PCs and devices to share one Internet connection
* Printer server supports Windows 98SE/ME/2000/XP, Macintosh and Unix operation system
* Easy to upgrade: using Web or windows utility to upgrade firmware

Two new box was given to me for VPN test and configuration. Tried to read the manual though..even my colleagues kept saying its very easy. Its best to understand every word in it although we knew the procedure to make it run. Basically, my standard test setup consist of a Zyxel DSLAM connected to the Internet, two DSL CPE representing 2 different subscribers, a laptop and a PC.

VPN Features
Site to Site VPN
Yes its cool, its site to site VPN is very easy to configure, however it's NAT is by default disabled. It took me a day looking for a procedure how to enable it. Their email support is not that really helpful too. I upgrade its firmware, hoping to see the NAT option displayed in the menu. It turn out that the NAT option can only be seen when the WAN side is configured with a Static or Dynamic IP. Since i set it in a PPPoE, NAT option is not displayed. No wonder, our field technicians are having problems.

Built in VPN Server
Tested it and its ok, however number of remote clients who can connect is limited only to 5. But for a 5 branch office, this box is definitely a cheaper and effective alternative. Its PPTP and L2TP are good.

Block sites according to domain and URL. Filter traffic according to port and IP Address. Well, whats cool is the schedule rule, which allows you to set specific time where you can run a specific rule. For example, internet browsing time is only 6pm to 7pm. Then port 80 will be blocked for the whole day and will be open only every 6pm to 7pm. Hmmm, a good one for staff who exploit their VPN connections with downloading of x rated files in the Net.

Have been tinkering with this gadget for a day now....better move on to the next one. Bye dude.

By the way, it is also a built in Printer Server. Printng a document from a PC in Davao to a printer in Cagayan de Oro through VPN is definitely cool huh!

Gearing up for our Christmas Party is in the air and everyone so busy about everything. Parties, gifts and presentation were the words buzzing in every nook of this 4 story building. And i was thinking that all people thought that when your in IT department, youre a nerd, wearing eye glasses, talks like an alien from another planet since you speak of abbreviations and codes. Talks like an alien...that is weird..but i was never like that. So i told my colleagues in the office, its time that we show them what IT guys are really made of. So we agreed to do a song presentation. Basically, it would be a kind of an acoustic thing. Perhaps if everything would be ok, we will have a bass and a two acoustic guitars to accompany me. Hehehehe, so i would be singing after all. Another year and i am here singing again with another company.

However i miss also the people from the old company i was part before. Those people were really full of vigor and enthusiasm. We had a dance presentation that time, where i lead the technical department. Luckily, after may years (daw) we have garnered the 3rd place award. I miss the friends i have there too, sometimes there are people that are unforgettable, although they already have forgotten you.

Well got to go, i have to fine tune this voice packets coming out from my esophagus. Hopefully, QoS will work this time, prioritizing the good tones before the bad ones.

another DSL simulation test

Just planning the possible simulation test for our DSL services. Hmmm...each port will have multiple channels with different service levels and prioritization. It just like one big pipe with a number of small pipes inside. Now in that one port, i can allocate services for each channel and identifiy its prioritization. Okey, let me translate it to simpler words. A client with DSL can have internet, data and video services just using one modem and one port from our DSLAM. Voice and Video will have a separate pipes each and will always have the prioritization when transmitted. In this way, its just like voice and video will be running in a separate pipe but still they are part of a bigger pipe. Hmmmmm....Triple play as they say..With this kind of technology i can give you an internet access and at the same time can allow you have services which are locally accessed such as video server, game server or a voip server. Well, i have my two Zyxel Prestige P660R modems, Zyxel 1248 DSLAM, two patch cords, two Telco SIP gateways, two Level-One switches and a black-cased Pentium 4 PC with an 80gb SATA and 512mb memory in my table. Looks like i am ready for some heavy testing. Well i have to tell K0l0s0s that i have to tap in his Softswitch to make this work. Just another day....and Christmas is in the air. How i wish those people in the 4th floor would consider a Bonus earlier for the people below. hehehehehe.

What a Life!!!!....Its so hard

I was standing in front Ororama Superstore, and minutes have already passed and i am still wondering why and how did i spend my 1,000 pesos. With all the skyrocketing prices of goods now, i dont know how will i survive every day. Christmas is fast approaching, and im still thinking how would i buy that 150 pesos exchange gift for our christmas party. Life so hard nowadays....sometimes i would ask myself, how much more can i do to change everything. For the past years, i have always been working. And in that long time, i have prove to be at always at my best, in every company i was employed. I have been very hardworking and every one in my family knows that. But, why until now i am still having a hard time?....earning money that is almost not enough to sustain.

Yes, people may say that what i am doing is not enough...but i have been consistent in every way. I have been always ambitious and not stopping in improving my abilities and skill. Today i only have 30 pesos left in my pocket...and God, i have scratched my head enough to think where would i find money for tomorrow.

Win XP networking troubleshooting tips

Prob1: can ping public web sites but browser cannot display web pages
Reason: Possible DNS corruption or caching of negative DNS queries

1. Click on Start Menu, Click Run, type cmd
2. Type on DOS prompt "ipconfig /flushdns
3. Enter

If problem still persist, possible winsock dll corruption

1. Type on DOS prompt: "netsh winsock reset catalog"
2. Or you might want to reinstall it by typing "sfc /scannow" in the Run menu.
3. This will check the corrupted DLL and will restore it from XP CD installer.

Prob2: cannot ping even modem is connected
1. assuming cables are already checked and anti spyware is run.
2. Reinstall TCP IP
3. Click START, Click RUN and type cmd, then type at DOS prompt "netsh int ip reset c:\resetlog.txt"
4. You have to set the IP again if it has a static IP.

See you on next having fever lately.

working at a very young age

i was riding on a jeep near the carmen bridge , when a wet, rugged looking kid alighted towards the front seat. He is probably, 8 to 10 years old and he is carrying a wooden box filled with cigarettes and candies. It was already 6 pm and raining hard. He was so wet, yet still managed to smile when the driver ask for a cigarette stick. What a kid....he is supposed to be in school not on the streets selling cigarettes. I can still remember when i was in the same age. I was a grade 3 student in a public elementary school. I sell candies and the locally cocunut made "tira-tira" to my seatmates during classes. And on saturday and sunday, i roamed around Nazareth and Macasandig selling the cacao chocolate "tableya". It makes me smile when i remember that i used to sell my goods first to the girls who has a crush on me in the room. You know, elementary days were quite full of childish i take advantage of it. Sometimes, the girl i visited would cry to her mother begging her to buy my "tableya", just to impress me in one way. really make me smile. Im not so much a good looking but there were quite a few girls that appreciates me that time unlike when i was in college (smile!)....Also there was quite a situation when one of the girl's mother did not pay her dues, and i have to visit them everyday asking for the payment. The girl was too embarassed then that she will not come out when im there...i was grade 4, she was grade 3.

However, inspite i was already selling that time, it never occured to me to stop going to school. I was determined to finish my education. That time i always think that the only thing that can make me rich was to become an engineer. I cling to that belief surviving every hardship i experienced in the way. And now i am an engineer..but still not rich....hehehe perhaps theres a time for everything under heaven. I just believe that i have to go on..and never stop until my last breathe.

Sometimes when i see these working street kids, i would think that if only i am a millionare i would build a school exclusively for less fortunate kids only. I was a working student before and it was really hard then. Going to school in the morning and working until dawn. Worse,i was taking up electronics engineering at regular schedules in MPSC. So during class, i really sleep because of stress. Reason why ladies doesnt like me that much before..i was so thin and groggy at all times...hmmm or im just not really good looking hehehe. Perhaps i have to admit na lang.

Well, to end this narrative story of mine, i just want to tell everyone that perhaps education is expensive nowadays, it is the only way we can survive with a little comfort perhaps in this wild world. Work if you want to, but never stop going to school, it is the only next big step you can take apart from working on the streets all morning.

Hardware Review 2: Wireless Radio

One of my favorite BWA radio Airspan AS4030 capable of up to 45mbps data rate and operating at frequency at 3.5ghz frequency. The equipemnt is quite good especially with it's built in bandwidth management which allows using of service flows with corresponding priority. Which means, you can allocate fixed bandwidth for each traffic and identify the priority of each one. Streaming traffic such as voice will have the first priority and a fixed bandwidth in the pipe to allow trouble free voice communication. The coolest part is that it has 8 built in E1 ports which you can use for TDM channels. Well, with this ports, we can extend the PSTN services to a nearby remote location wiothout the need for E1 converters. It is more of a TDMoIP technology, which allows TDM over IP.

Another WiFi radio is the russian made Infinet Wireless Router. Imagine a router, bandwidth manager, VOIP gatekeeper, vpn endpoint and QoS all in one. So much features inside that i doubt if it is capable of long distance range. I heard it has an amplified version which has a built in amplifier inside the radio. But tried to test it, and its performance on voice stream was excellent. Even the response to streaming traffic, is much higher compared to other radio. Definitely an all in one wifi radio in the market.

VoIP again....CDO call center coming

here i am staring at my pc in the office thinking...wondering how would i present such technology in a very simple way that would make my audience composed of marketing and sales people understand. We have been launching products on VoIP such as call center solutions, Voice over Wireless, Voice Over DSL, etc. In one word, its VoIP. Kolosos my colleague from Network Management Center have just discussed with me the basic architecture of a PSTN network against a VoIP network. Well, it is much alike though by principle...the only thing that differs are the protocols, the medium and i guess the hardware. Right now, everyone here is so busy about this local call center in Lim Ket Kai which is about to launch this month. It has been 3 days now that everyone is discussing possible setup and configurations to come up with the best solution for this new local call center. This would be definitely the first CDO local call center. Ariba!!! let me hear you say yeah!!.This would be the second call center in CDO that we will be supporting but this new one is the first one where we design the whole call center solutions including the server and clients. One tip, this one is own by a prominent cable tv operator here in Cagayan de Oro. I bet that would be a bunch of good looking ladies there in that call center. And its funny that the site was the same site where the famous high class bar "Pyramid" was formerly located.

DSLAM training on Zyxel IES-1248

We just had our training on Zyxel DSLAM conducted by engineers from Zenshin Systems. Some stuff on configuration and troubleshooting were discussed, also open forums regarding existing problems on CPE's and DSLAM configuration. But what interested me was the feature on multiple PVC. With this feature i can dedicate a connection to each services and route it through a VLAN switch. Separate connection for voice, video and internet browsing. I can also create a separate PVC for management purposes only. Separate VLAN for subscribers and for our network is also a good one, so we can protect our routers from possible attack from DSL subscribers. However, the best part of the training was the free jackets given to all participants. Hmmm, if all suppliers are like this, you bet their names will always be remembered.

By the way, i think i have to do several simulation test these coming days, to verify its features. As of now, i am still drowning myself from this myriad of wireless equipments.

By the way that picture above is during the DSL training i conducted to Marketing and Sales Department. How in a hell, it pop up in this post hehehe...well just leave it there.

High Ridge at Aluba Macasandig : CDO's newest tourist spot

I was surprised recently when a huge banner pop up infront the house, and a huge post saying "High Ridge tourist spot destination overlooking the city THIS WAY" Then i began to notice several vehicles going up to the place we once called "The Heaven". The place was once closed by police because of so many teenagers are coming there bringing with them liqours. Lovers and couples in the past once enjoyed hiking to top, bringing with them food and having picnic while looking at the wide horizon above the sprawling city of Cagayn de Oro. I remember, we used to sit down in a sampaloc tree just meters away from the Liberty Transmission Tower . But after several months last year, the place was closed down at night because of so many visitors drinking, pot sessions(daw?) and sometimes car sex (whew! doing it under the moonlight..hehhehe). Then last month, the place was declared a tourist spot. We thought it was the same place, but it turn out to be farther from the place we knew as Heaven. Last night, we visit the place and it was beautiful. Approximately a kilometer away from the highway below, we travelled by almost 15 minutes until we arrived there. We arrived in a wooden gate with a name High Ridge, then we follow a narrow path which leads to the restaurant. Entrance fee is 50 pesos which is consumable. They said the restaurant is a branch of Dear Manok, since it was owned by the same person. Th place was not really spacious but there are tables and the chairs in the ground. There were green and blue lights decorated on palm trees. There are also tables in the ridge area, where you can dine while enjoying the sight of the whole city. A good place to dine, chat, think (?) and maybe to show off your romantic juice to your partner. It is an open ground, where you can see the stars above and the yellow lights emanating from the metropolis. Too bad it rains when we were there, so we did not enjoy the sight so well. But for all of you who wants to visit the area just follow the road to Aluba until you will arrived in an intersection where the left road leads to Libona. Youll find the banner there and the arrow signs. You will notice also a closed small store in the second house, dont mind that, coz it is where i live hehehehhe.

Got so busy with wireless

I felt my head is already vibrating already because of the radio signals coming through in and out of my brain. It feels like i am inside a microwave oven and waiting for my brain to be toasted and fried by these microwave frequencies. 2.4Ghz and 5.7Ghz becomes my bestfriend nowadays. I was assigned as the lead engineer for the wireless testing team which is responsible of testing all wireless products being submitted to us. We are currently working on the tranche 2 wireless data expansion in Mindanao. Gosh! wires , antennas and radio are cluttered in our makeshift wireless lab which consist of 2 PC, Voip gateway, qcheck software, traffic emulators and asterisk server. Hopefully we can purchase the test equipment we have been waiting for. Beside the wireless lab is also setup for DSL testing. We have radios from Infinet, Motorola, Trango, Proxim, SkyPilot, WiLan, Angel, etc. By the way, we have the 25 percent weigth for the wireless product that would win in this project.

Windows XP Built in traffic monitor for spyware detection

Last time, i recommended to internet cafes who have problems with spyware to use packet sniffer instead. By detecting the source IP and the ports, they can easily pin point possible PC suspected of spyware infection. However, i still thought that there must be a better way to detect abnormal traffic within the PC aside from using some freeware bandwitdh monitors. So i have here a very basic tech tip which you can use, when you feel those freeware are not that reliable.
1. Just click on Control Panel - Administrative Tools - Performance.

2. Delete all existing counters and add a new one.
3. Click on add counter icon and click on network interface.

4. Add the packet/sec counter or you can also include the packets sent or received.

5. Normal traffic may look like this.

6. Abnormal traffic (possible spyware infection) may look like this.

7. When a certain download or upload is interrupted, this is the graph that you will see.

So next time you experienced slow internet access, try to stop all internet activity on each PC then observe the traffic of each interface. Abnormal increase of packets per second on that inteface even in the absence of internet activity may be caused by a spyware or a virus.

Freeware Review 3: WhatisTransferring

Past few days, i was answering to calls from internet cafe regarding slow internet access. Tried to check our monitoring and it shows most of them consumes 100% of their bandwidth. After checking our modems and connection, it turn out that some of their PC were infected with spyware. Well, they can just clean up their PC and the problem is gone. However, with more than 30 PC with users online, it would be a bad timing for the owners, since it would mean loss of income at that moment. Well, ISP cannot do nothing more, since the problem is within the Local Area Network. Then I thought of using a packet sniffer which must be lighter than Ethereal so that it can be easily downloaded and the same basic features to capture packet. With primary objective of knowing the source IP which is broadcasting too much UDP/TCP packets and what ports it is using, i came to use the freeware WhatisTransferring. Using the freeware, you just observed the Source IP which broadcast too many UDP or TCP packets, then take note of it. Then you can start disconnecting it from the LAN and clean it up first. In this way, you dont need to shut down the whole network and you can isolate the cause of the problem much faster. Well, there are many freeware you can use there, but i think this one is good.

Love Story 1 : The Wood in the Island

It was a beautiful was blue, waves were catching up with one another, as if they are kids running around..innocently playing in the vast sea. It was 5 years ago where in the same sand i sitted, the same rock i held and the same beautiful day that i shared my most unforgettable moments with my bestfriend.....

I was lost and lonely. I cried for so many nights asking myself, why and how. The desperation and dismay i felt against the many things that has happened to me were choking me. Rex was again with his friends, Stella was asking for her school allowance and my parents were sick and i cant even afford to buy even a cheap vitamins for them. There were so many of them around me, but i felt i was so alone and isolated. Sometimes, i woke up in the middle of the night, crying without a reason. I cried for hours and silently screaming the pain i felt deep inside. I want to held my breath and drowned myself with my tears until such time i will feel no more pain and emptiness.

Then one time, I was asked by my boss to visit a certain island, to take pictures for our travel agency. The island was beautiful indeed. The scenery brought me inner comfort for brief moment that i was away from the city...away from my family and Rex. Then, for the silly of me, I thought of putting a wood beside me while I sat down in the sand. Then holding the wood, as if it was a human being, I make sure no one is looking and began to talk about my problems, my family and my dreams. I barely notice that a man was actually beside me, listening to my blabbering. To my surprised and embarassment, i quickly stood up and angrily ask him. "Who are you and why are you here?". Mam, actually i was here before you came. he smiled and pointed his finger to the tree beside me. " I was there up in the tree, i like to sit there and spend my time watching the horizon until it dawns.Do you like sunset mam?" "Amely is my name Mr...." Karry, im Karry. By the way Amely,can i ask you a question? I nodded. " Did the wood answered you back while your talking to him?" he smiled. I laughed hard, and for the first time i was laughing...we talked the whole afternoon until the sun sets and I have to go back to my hotel. He waved goodbye and said. " Amely, good night and see you tomorrow". I did my task, taking pictures in the morning and going back to that tree near the sea every afternoon spending my time talking and laughing with Karry.

And for the first time in my life, I felt i was not alone...that i have a bestfriend...when in fact we just meet few days ago. I felt so comfortable and at ease when im with him. He makes me laugh with all his corny jokes, and makes me smile with his slapsticks. One time, he stands up in front of me and sing his heart out to the tune of Love moves in Mysterious way. It was a high note song but he sang it well than a woman. It was my last night in the island. For the days i stayed in the island, i felt i have found a bestfriend that i have been looking all my life. Hey Amely, i have a gift for you and i will give it tomorrow. Keep it so youll be reminded of me always." as he giggled like a child. I smiled too, but i felt heavy as i looked at him." Well see each other again Karry, ill visit you again".

I was packing my things and i am ready to go. Then i thought of visiting my bestfriend again and perhaps ask him to come with me for a vacation. Then i can tour him to our City and we can talk longer. I can ask Ray to accomodate him temporarily in his boarding house. I was excited to the mere thought of it.. i was running to the tree and calling him..Karry! where are you?. No one anwered instead a little girl was sitting there and crying. I asked here. "Hello, why are you crying?" The girl looked at me and said. " Your Amely, are you? my brother talks about you always at home. I held her. " Your Karry's sister, how are you? where is he?. She looked at me again and cried." He just died last night of heart attack". I cant move. " Your kidding right?. My brother has a rheumatic heart, he takes a rest during the day climbing up that tree and watching the horizon until sunsets. I was speechless, as all the tears came flowing from my eyes. I have found a bestfriend...and i lost him. Then the girl held me and said. " by the way, before he died he gave this to me. It has a name engrave on it". It was a small wooden bust of a man with an engraved letters " to my bestfriend". A small note was attached to it. And it reads "this is made from the wood you have talked to for hours, i will miss you".

Hardware Review 1: Zyxel Prestige 660R DSL Modem

Zyxel DSL Modem has a quite a good form, which can be a factor in marketing appearance. Its blue and sturdy look provides a feeling of reliability and high performance to clients connected to DSL services. It has the same basic stuff inside (NAT,Port Forwarding, SPI, Access List, Routing, Bridge, etc). However i was interested on one feature which is the IP Alias. IP Alias is the capability of one modem to share 1 public IP to 3 different network. Which means, that i can connect 3 VLAN's or different LAN to internet access and denied others without the need to put in a router or a layer 3 switch. For example, I have 3 VLAN's for each department which is Engineering, IT and Customer Service. The reason for the VLAN is to separate each department' network, to improve security and access to dedicated servers. However, i need to connect Engineering and IT to Internet but still maintain their VLAN ID. With IP alias, we can just easily connect the two VLAN without the need to change their IP or disable their VLAN assignment. It's a simple feature but helpful, especially when IT budget is limited.

Other feature also is the address to address mapping. Which means you can map several public IP to different Private IP. For example, you have 3 servers in the data center. A VoIP server, Application server and a File Server. You need to separate each access, so you assign each with public IP. However, your concern with security, so you need to assigned it with a Private IP, while doing NAT to mask your LAN IP's. Others may opt to do routing, but with this modem, you can keep the NAT and still come up with the same objective.

Freeware Review 2: Traffic Emulator

Are you trying to measure the reliability of a server, router, firewall or any access point? Well check this freeware! You can simulate a heavy traffic client-server activity and stress test your equipment. By setting the number of source IP address which will generate the traffic, the number of packets they will send, the type of protocol (TCP,UDP,ICMP,Others) and the destination IP of your equipment,your ready now for some major loadin'& killin' stress test. Download it HERE dude! See more of the freeware i used to troubleshoot network problems on my next posts.

Freeware Review 1: Qcheck performance test

I was assigned to do the performance test for Motorola Canopy Access Points and Subscriber module. With the absence of a reliable tool, i have to search for some software in which i can do comparison. Basically, i need the response times, throughput and streaming test. Then i stumble upon these freeware from IXIA, which is very useful for a basic network test.You can select what protocol to use (TCP,UDP,IPX,SPX) and set the data size for response and throughput test. You can also do streaming test with UDP or IPX protocol at different data rates. You may want to check it it out HERE.

VoIP for all! long distance no more?

VoIP or Voice over IP has been recently a hot topic in the news lately when NTC released its official stand about it. Read it here. Classifying VoIP as a value added services has sent a wide grin on the faces of companies who despised long distance charges. However, telcos were not quite amused by it, considering that every ISP in the country can host voice services to compete with the "giants" in the telecommunication industry. Imagine this, a 20 year old IT whiz geek who pride himself on his expertise in configuring a VoIP server using a high end PC clone, will just need to have 3 to 5 trunk lines and a high speed bandwidth internet connection then viola! a full operational Voice services for US pinoys who would like to call their CDO relatives at a lower cost. All they have to do is connect to the VoIP server through the Internet, register, subscribe, send their payment through Western Union and they can call Cagayan de Oro. Then guess what happen to the kid....well he become rich.

Now how in a hell can we do that? I have seen solutions from popular brands. We have Avaya, Cisco, 3com, Huawei and etc. who have sell complete solutions on VoIP. But how about for those offices that needs to connect to VoIP and doesnt have enough money to invest on 10 thousand dollars worth of machine? Consider a company with 3 offices in Luzon, Visayas and Mindanao. Manila needs to call their sub offices everyday for reports and stuffs. And these suboffices needs to call their Main Office and other suppliers in Manila everyday too. From the sound of it, you think of thousands of dollars in equipment alone. However, what if we can make an alternative solution which is much lower and cheaper but the same functionality. 1000 dollars high end PC to be used as a VoIP server, 100 dollars FXO gateway, 2 units of 70 dollars FXS gateway and snacks, professional charges at 1000 dollars maybe or less...then you got your system. All in all we have 2,240 dollars for an initial invetsment on a full operational VoIP system.

The secret of this cheap alternative solution will be on the VoIP server which basically was a Linux Open Source PBX technology. For those who are interested or who are looking for an expert on this, our group can certainly help you in so many ways. Please email me, or for details and inquiries.

What makes Linux so popular among IT geeks?

With the recent operation crackdown on pirated copies of Microsoft, several establishments have opted to use Linux based operating systems. Of course, there were so many complaints from users, especially those who were more familiar with windows. I came to visit a popular Linux group forum, KLUG and i noticed that some of its users really hates windows OS or sounds like they hate it..or im not sure if its just a show off. Now the question, why is it that if we talk about linux, we associate it with IT experts, geeks, hackers and computer whiz people. Sometimes, the qoute "I know Linux" is another term for "I am an IT expert". Well, each operating system has its own features and vulnerabilities. Some may choose one from another, it really depends upon ones expertise and strategy in managing its own network. Some may prefer Windows because its friendly, easy and has a strong tech support. Or others may prefer Linux, because it is open source, free, reliable and has less vulnerabilities. But in my opinion, there are reasons why IT geeks prefer to show to all thay they prefer Linux.
Aside from its technical features, psychologically these are also be partly their reasons.
1. Linux is unfriendly to a user who has limited IT knowledge. Which means that MAJORITY of us doesnt understand it. So if you understand it, and knows how to use it, then you can be consider as the FEW WHIZ out there. Sometimes beng with the few, is what makes us feel special and extraordinary.
2. Linux is more of a CLI instead of GUI, which makes it unpopular to ordinary users.
3. Linux is open source, which makes it basically free to download and to use. So if you are a linux expert, then "free from licensing" is your war banner to all companies out there.

Others may argue that Linux is better, or Windows is still the best, i think its just the same. Those software were developed to make our work much easier, effecient and productive. Expertise depends upon the features you need to squeeze out from an OS. All i can say, why windows is much popular, it is because they have the most brilliant minds in marketing. They can mask and hide the vulnerabilities of their product through features available. But in fairness. Windows has some features in which are really good and easy to manage.

Why Cagayan de Oro is the Best?

I was going to my work when i boarded a Patag liner in the corner of City Hall just near the Lourdes College. I was looking and enjoying the beauty of the two floating restaurants in the Carmen River, as the jeep was crossing the bridge. Then i realized that the beauty and grandeur of a city will really depends upon the people that lives in it. Cagayan de Oro is known as the City of Golden Friendship, and we have proven and affirmed it to all visitors that came to the city. I worked for 2 years in Davao City and i can really see the difference of the people there from ours. Dabawenyo in majority were more of a socialite and arrogant. Although i do have down to earth and kind friends in Davao. You've got to be "in" to be acknowledged. In fact, if you want to be respected in a mall or any office, you have to speak Tagalog, even if it sounds so Bisaya. Have been in Cebu City for 8 months for my board exam review once. In Cebu, you beware of sweet smile and good intentions shown to you by strangers. It may be a snatcher, modus operandi or a rapist waiting to capture you. Never wear a jewelry when youre in the city nor display your new cellphone, i tell you that is dangerous in a city like Cebu. Im not really biased, since i have been to several provinces and cities in my previous work, but there is no City as warmth and friendly as Cagayan de Oro. You might ask why? I can give you a few reasons:
1. In Cagayan, we do not imitate other Cities and pretend to be high class by speaking languages which is not ours. We speak Bisaya at our own unique intonation and speak tagalog only to those people who do not understand our Bisaya.
2. In Cagayan, people smile a lot because were happy and beautiful (applause cagayan!)
3. In Cagayan, streets were safe even in the wee hours of the evening because we have huge post lamps that illuminates every street in the city. And we have police who are vigilant and a mayor who cares about us (is it election already?hehe)
4. In Cagayan, we have large and shiny with all the lights accessories JEEPNEYS! (try to check Cebu and Davao)
5. In Cagayan, TAXI are Toyota Corolla, Nissan Sentra, Vios, etc. Complete with aircon and stereo sounds. (check Davao dude!)
6. In Cagayan, we have Night Cafe, where people whether rich or poor, socialite or not meet, drink and dine every Friday and Saturday of the week. People in CDO are one, we dont biased people based on their status or language.
7. In Cagayan, people loves to sing and are good singers. We have Mark Bautista and Aegis to prove that. We have videokes everywhere.
8. In Cagayan, we have the cleanest and beautiful markets. Check our Carmen and Cogon Market and you will probably say, "hey thats not a market, its a superstore!"
9. In Cagayan, we are the city with the most number of Telcos. We have Philcom,Sotelco, Cruztelco,Italtel, Misortel, Bayantel and Globe. See how high tech we are? but Philcom is the most popular of them all here (Go Philcom!)
10. And most of all, ONLY IN CAGAYAN you will find the best tourist spots. So biyahe na! WOW CAGAYAN TA BAI!

There so many things to say about Cagayan but i think one good reason why i love this City is because i was born here and i live here. There is no place like home i guess.

Badminton Match at the Sports Zone

This my new blog site. Just played badminton with my batchmates yesterday September 17,2005 at Sports Zone in Tomas Saco, Macasandig. Together with Anton of NMC-Philcom we battled against the unorthodox style of Alex of MPSC and Sanchez of HarvestSeo. Teresa of NMC-Philcom serves as our referee. After a gruelling swish and swak, we lost by 4 points on the third round. It was a good match i think, even if i have difficulty in walking afterwards because of a sore feet due to my cheap shoes and socks. We paid 300 pesos afterwards, since we consume 2 hours in the court. I liked the ambiance of the place, its peaceful, clean and arranged. I also noticed a boxing gym in the corner filled with equipments for jabbing and punching. There are 4 badminton courts available in the area, 2 has a wooden floor while the other has rubber on it. Wooden courts are priced 120 per hour while the rubber courts cost 150 per hour. One thing i like about the place is that its safe outside and there are tables and chairs, where you can sit and drink for awhile. My body is aching but i enjoy a lot. There is no refreshing experience more than enjoying and exercising your body in a badminton match. It is an ultimate unwind experience, instead of staying at those dark and noisy bars.
