The Bidders' Tour to UPCM's Network Jungle
Three bidders for the network auditing tasks in UPCM conducted an ocular inspection to the main switches in the college. Following the call from the college for companies that might be interested in the contract, Cylix Technologies, Winsource and MFL visited the location in each UPCM building where the main network cabinets are located. Also included in the inspection was the UPM data center located at the University Library

APT Telemedicine Conference June 14-15, Okinawa, Japan
I attended the Asia Pacific Telecommunity (APT) Regional Conference on Telemedicine. This coincided with the 21st Pacific Science Conference at the Okinawa Convention Center. Prof Isao NAkajima was gracious enough to invite the Philippines to present the country's initiatives in telemedicine.
We were billted at the Okinawa Washingto Hotel and took the shuttle bus from hotel to convention center daily. There is free wires Internet inside the rooms.

Massive network disconnection
As reported from the MIU mailing list:
Dear all,
Sorry for the not so good news. Early Friday (Jan 19), internet users of UPCM experienced an erratic connection to permanent disconnection of PC's in the network. Upon checking the possible points of network failure (dagohoy, main switch in SPADE, switches) and consulting Jay of IMS, here are the findings:
1. The UPCM segment was disconnected automatically due to a series of warnings and error messages in the core switch according to Jay. He later enabled the connection for us to find out the cause of the problem
2. We checked the main switch in SPADE. A laptop was connected to the 24-port switch. Just like the other machines in CM, the machine was able to get a 169.xxx.xx.xx IP address.
3. The converter in the SPADE main switch should have three blinking lights (power, fiber optic, LAN). The lan cable (straight) was disconnected from the switch and connected in a laptop. The LAN bulb went off. Jay suggests to use a crossover cable instead. When the crossover cable was re-connected to the laptop, the LAN bulb lights up but the machine still gets a 169.xxx.xx.xx IP address.
4. To check if there is a problem with the switch, we disconnected the uplink cable from the converter and replaced it with a MyDSL line in Dr. Balgos' office. All LAN cable were removed except the one connected to the laptop. The laptop was able to get an IP from the MyDSL router and can connect to the Internet. This might mean that there is no problem with the switch.
5. As of now, the main suspect is the media converter (the one we borrowed from IMS). We hope to test another converter but we don't have any available supply as of this time. Jay also mentioned the possibility of some desktops that causes network interruption due to virus.
The next action will be to test another converter just to make sure that this hardware is the cause of disconnection.

Mga kaganapan ngayon Jan 12 2007
Umaga:
1. Ini-isolate ang sarili upang makapag-concentrate sa RUMIS. Tanging mga building managers lang ang pinakikinggan regarding the sa correction na pinapagawa nila.
2. Gumawa ng letter/report of findings tungkol sa pag-mal function ng computer ni Ate Leonie. Justification din ito para sila ay mag-request ng panibagong PC. Ang IBM netvista ay maari na lamang gamitin sa text-based OS tulad ng Linux servers.
Hapon:
3. Nagtungo sa NEC para kumuha latest PhilMIS 2 source code for deployment and trainig and training. Kailangan gumawa ng 2 bagong setup files na integrated na ang data from Davao Del Sur and Davao Oriental.
4. Nag-check ng mga conmputer na connected sa opisina ng mga DMT members. Medyo erratic nuong nakaraanga araw, pero ngayon ay OK na.
5. Naghahanda para sa 3 meeting sa Monday. 11AM - Ad Hoc Committee on Office Equipments, 12 NN: Dr. Wang and Dr. Marcelo c/o Online Faculty Database, 1PM - Commitee on Facilities and Physical Plant c/o ADPR
