I know it's not much help now, but I have a *very* small list of things
I *never* do remotely:
1. kernel upgrades (if it bonks on the BIOS level, no remote daemon can
save you... the only fix would be a magic box that tunneled raw VGA
output, raw PS2/USB input, etc. over TCP/IP... is there such a beast?)
2. RAID juggling (if /boot is on a SCSI RAID 5, for example)
3. For that matter, anything SCSI. Requires waaaay too many goat
sacrifices when *at* the console to even consider doing remotely. (Or,
alternately, really good high end cables and terminators, which I
*never* seem to see IRL.)
4. Any crypto library changes, or pam changes, if my sole admin access
is ssh. (Want to know how to make an sshd session work when the daemon
dies because libraries have changed? So do I.)
5. ifconfig changes (without a crond/atd backup script to restore
settings) on single NIC machines.
6. For that matter, ipchains/iptables/ipfw changes (without a crond/atd
backup script to restore settings) on even multi-NIC machines.
Anybody else have warnings to add to the historical pool of "Ooops", so
future admin folks can spend less time pounding their heads mercilessly
into keyboards?
