Help – does this ring any bells?
I was upgrading a 10.4.11 Server (Xserve G4 Dual 1.33 GHz) to 10.5.8 last night (and, sadly, into this morning).
All was mostly copacetic, but then I made some change (not sure which) and the next thing I know, Server Admin isn’t coming up, it just hangs.
Decide to reboot, it rebooted and then I couldn’t enter anything into the login screen’s fields.
Tried to SSH in, it connects to port 22 but no SSH banner returned (tested with Telnet) and it hangs forever.
Can’t AFP mount anything anymore.
Basically, I can’t access the box at all at this point.
One change – maybe it was to DNS, maybe to the Firewall (perhaps denying a localhost packet to the LDAP server – who knows – I had replaced the existing /etc/ipfilter/ip_address_groups.plist file with my old one from 10.4.11, oops) and the whole damn thing unravels.
The old 10.4.11 Server installation is still intact on the other disk, so in a pinch I can hook up a monitor & keyboard and boot it with Option back into that for forensics. Or try booting into Safe Mode.
But I’ve never seen a case where twiddling some file caused the whole damn box to be unresponsive like this. I just wonder what the Hell did I do to cause this?
