UMIACS RHEL5 Reboot Thursday November 4th 8pm-10pm

Because of a local security exploit in the kernel we will need to reboot all RHEL5 boxes (Except Bug/Crocco Clusters). Please make sure to save your work and we will strive to have all boxes back before friday morning. We apologize for the short notice however we need to take these steps to ensure the security of the site.

Comcast DNS Issues

We are currently experiencing issues with Comcast home internet in PG county not correctly handling DNS resolution for UMIACS hostnames, that can seem to be affecting connectivity to UMIACS.

If you are having problems getting to UMIACS hosts you can use our name servers to resolve those specific host names then connect using the IP addresses you lookup. Our name servers are 128.8.120.19, 128.8.120.50, and 128.8.132.75 to use this information to get the ip address of the host somehost.umiacs.umd.edu you would use the command "nslookup somehost.umiacs.umd.edu 128.8.120.19", from a linux, windows or mac command prompt.

Unfortunately the problem seems to lie in an interaction of Comcast's name servers with those run by OIT, but we are looking into ways we can interact with those parties to get this issue resolved. <endFeed />
