The multi-user Solaris machine argus has been shutdown due to an unpatchable local root exploit.
IDSG currently has a trouble call in to Sun to address this problem and will bring argus up as soon as the problem is resolved/mitigated.
UPDATE
[2005-06-29 01:49:35 | Mark Kraitchman, IDSG staff]
Argus has been secured and is back up.
