We know the DNS servers at that point in the install process, I'm pretty sure, so we can just resolve the hostname. This is useful because I'm much more likely to (reliably) know the hostname of the system in question than its IP address, especially in places like W20-575 where the hostname indices are roughly one off from the last IP octet. (Except where it isn't.)

On my lucid VM, with openjdk-6-jdk 6b18-1.8-0ubuntu1 and icedtea6-plugin 6b18-1.8-0ubuntu1, the Athena registration applet (  http://web.mit.edu/register) is not displayed consistently. It failed to display the first time loaded in my tries, then usually (but not always) was displayed when I reloaded the page. Running firefox in a terminal, I see:

The NPE seems to correlate with the applet not appearing.

I saw no problem in a brief test of the Sun JDK.

We have traditionally recommended running data-intensive simulations into /tmp or other local disk, as this is both faster than AFS and does not eat up quota. Unfortunately, it appears that the current chroot configuration only provides 1G on any particular local filesystem. geofft seemed to think that it might be okay to mount /tmp as an actual disk; if that is not a useful option, we should at least be able to give a few more gigs on one of the devices in the chroot.
