Found the problem... Something had hosed /etc/security/console.perms. I had just (over the weekend) installed Centos 4.3 on a box at work, so I VPN'd into the office and looked at /etc/security/console.perms there and saw about 25-30 lines at the top (mostly but not entirely comments) that were missing in mine. so I did a copy-n-paste bit, rebooted, and got the error about "unknown class dri". I'd already seen several postings (googling) on how to fix that so I did, rebooted again and was golden. Curious, though, as to what it is that hosed it. -- ---- Fred Smith -- fredex at fcshome.stoneham.ma.us ----------------------------- I can do all things through Christ who strengthens me. ------------------------------ Philippians 4:13 ------------------------------- -------------- next part -------------- A non-text attachment was scrubbed...
