I am in the process of fixing the userID and groupID numbers on the controls accounts so that the disk permissions are all good. In the meantime, things will be broken on ws2.
ws1, we are completely wiping to upgrade from Fedora 6(?) into CentOS 5.5. Unfortunately, its 32 bit and will need different apps. I will ask Joe to buy us a new workstation which can be 64-bit.
So in the meantime, you should ssh -X into fb1 to run DTT. You can also run DTT from nodus and just set its NDS server to point at the ATF. Or just use mDV and make a 'gyronoise.m' file and upload it to the SVN so that we can all use it.
