Portscans/PROXY scans
by John_York＠Dell.com 12 Nov '03

12 Nov '03

Hey gang, We're seeing an incredible amount of port- and proxy-scans from 211.0.0.0/8, and 0 legitimate packets from the same range. I'm thinking about blocking the entire /8, as noone on our network needs any contact with Asia (I belive those addresses are all in Asia - correct me if I'm wrong). Has anyone here blocked 211.? Any unexpected results when doing so? Thanks, John

All cooling units move heat from point A to point B. The end result is that point A gets cooler, but, and it's a BIG but, point B gets hotter. If you use portable coolers, you have to decide where point B is and can you get away with increasing the heat there? Will you blow the heat back into the development lab? Or into the office space next door? Or into the space above the suspended ceiling which indirectly channels the heat into every room on the same floor? Or under the raised flooring where it can raise the temperature of every cabinet that is not being cooled by the portable units? IMHO, portable coolers are a bad idea. They add noise to the environment and increase the overall heat level due to the consumption of electricty. When we had them in our office for a week, I started working 3 hour days to escape the hellish atmosphere. In the past I regularly worked in buildings that were 35 degrees Celsius indoors (2 degrees C less than core body temperature) and it was much more comfortable than that week with the portable coolers. --Michael Dillon P.S. it would be interesting to know if anyone has some creative solutions to data center design to cope with cooling system failure other than n+1 redundant coolers.

Point of sale RAS hardware?
by Jeffrey Paul 12 Nov '03

12 Nov '03

Does anyone know of a good RAS product that supports the fast train times needed for point of sale terminals (specifically the ability to turn off data compression, error detection, and speed negotiation)? Most every one I've seen is aimed at serving as-fast-as-possible dialup network access to normal modems, but I need something that will do 1200bps (or even better yet, v.22FC) with no frills. Can anyone suggest a product or manufacturer?

Might you be referring to a "MovinCOOL" by the company named DENSO ? We have one of the model 10SFU-1 - got them from the Grainger catalog. We named ours Snuffleupagus :) Dave Hilton Staff System Administrator entelos(r) Foster City, CA "Linux is like a wigwam - No Gates, no Windows, Apache inside."

Portable Cooling
by Fisher, Shawn 12 Nov '03

I searched the archives and couldn't find anything about a portable cooling units so am resorting to posting, sorry if its redundant. I am setting up a development lab and need additional cooling on a temporary basis. I recall a product called, "move n kool"? It looked like the robot on lost in space. They used to advertise in Boardwatch when Boardwatch was cool. (when Jack was running it) Not sure of the spelling, but wondered if anyone has had experience that or anything like it. TIA Shawn

Check with Home Depot, they have some for about $400 - from Maytag; also APC makes one, but not sure of cost or source. -Keith -----Original Message----- From: Fisher, Shawn [mailto:SFisher@Bresnan.com] Sent: Wednesday, November 12, 2003 10:43 AM To: Nanog List (E-mail) Subject: Portable Cooling I searched the archives and couldn't find anything about a portable cooling units so am resorting to posting, sorry if its redundant.

Router with 2 (or more) interfaces in same network
by Sugar, Sylvia 12 Nov '03

12 Nov '03

Hi, I am curious to know if its possible to have a router with its two interfaces, say configured as, 1.1.1.1/16 and 1.1.1.2/16. Theoretically, i see nothing which can stop a router from doing this. But practically, is it of any use? And if used, then, when and why will somebody want to use such a kind of configuration? Would appreciate if somebody could enlighten me on this. Regards, Rasputin P.S. I have a customer who insists he wants to do this, without providing any explanations! ________________________________________________________________________ Want to chat instantly with your online friends?

Lewis University (lewisu.edu) users are having problems connecting to my mailserver. Unfortunately, I can't get them to send me any useful traceroutes - they all die at the second RFC1918 hop. Anyways, if you're out there, can you contact me offlist? -- matthew zeier - "Nothing in life is to be feared. It is only to be understood." - Marie Curie

Nachi claims another college: Dartmouth November 7
by Sean Donelan 11 Nov '03

11 Nov '03

Almost half of all student computers on Dartmouth's campus have been infected by the Nachi/Welchia worm. If student's do not fix their computers by November 11 (nearly four months after Microsoft released the original patch), Dartmouth will turn off the student's network access. http://www.thedartmouth.com/article.php?aid=2003110701020 Has anyone figured out a way to get computer users to fix their computers other than fixing the computer for them?
