Server mirroring
by Priyantha 28 Nov '03

28 Nov '03

As a part of business continuity plan we are going to have all our servers replicated in a different place to which a fiber connection is available. (Currently its running at 100Mb) Servers are running mostly RH Linux 7.2 to 8.x and couple of Win 2000 servers too. I'm looking for a non-expensive software solution for this task. Your help is appreciated, Priyantha

Have worm? University upgrades network
by Sean Donelan 27 Nov '03

27 Nov '03

After sending out e-mails and notifying students, Dartmouth College has started to disconnect virus-infected computers. http://www.thedartmouth.com/article.php?aid=2003112001020 The service denials come after Computing Services sent out a campus-wide e-mail earlier this month announcing that over 2000 student computers were infected with the Welchia worm virus which was causing severe lag on the campus network. That e-mail instructed students in the steps required to diagnose and, if necessary, treat their computers for the virus. "Should the network's performance continue to suffer, we will be forced to deny access to machines that are abusing, however unintentionally, the network," the Nov. 6 e-mail warned. "We do not want to turn off your network access but we will to protect the integrity of the network." On the other hand, California State-Long Beach is planning to upgrade its network to deal with the worms. http://www.csulb.edu/~d49er/archives/2003/fall/news/volLIVno49-dorm.shtml Stan Olin, director of housing, said they are doing the best they can to get the problem fixed. Housing and network staff has been working around the clock to resolve the problem. Seven dorm residents are included in this team. They aid in tracking down infected computers and are responsible for ensuring students have access to the network. More than 200 infected computers have been identified. Housing notified students through voicemail and other means that anti-virus software is available in the hall offices. Depending on the hardware the student has, the software takes less than 30 minutes to remove the worms. Elson Browne, assistant director of housing, is finding that students are "not taking advantage of free resources." On the contrary, a freshman who requested anonymity said she tried installing the software but found it incompatible with Microsoft Windows XP. She said she now considers the situation "a lost cause." [...] The entire campus is in the process of switching to a new network, however, the dormitories were not included in the first phase of the process. The housing department said it was planning to upgrade sooner or later but due to the urgency, it is pushing for a complete upgrade by next semester.

If there is a Cox.Net contact on this list please contact me off-list. I have an issue where I cannot get to my MCI IPs from Cox's backbone. Thanks! Andy Ellifson

The Netherlands were hit as well. We saw a massive flood of queries for lockup.zonelabs.com, too. It performed a nice DoS on our client name servers.... :-( You'd think that an unresponsive nameserver would be flagged dead, and such information be cached. Does anyone know whether that's actually done in Bind 8.3.4? Or perhaps not by default? Cheers, Arjan H Not even a clue-by-four would work with this clown. ________________________________ dr.
