ufsdump / .rhosts / Solaris 2.4
Precedence: bulk
Situation in Question:
root@SomeHost having a Script running off cron which tries to
(ufs)dump Stuff to SomeUser@TapeHost. SomeUser@TapeHost having
restricted Shell, .rhosts, owns Tape Devices, all the Jazz.
Everything fine and dandy with .rhosts reading "SomeHost root"
on a 4.x Machine, but on 2.4, .rhosts all of a Sudden needs
to be "SomeHost SomeUser", though SomeUser@SomeHost doesn't even
exist.
Solution:
2.4 ufsdump is messed up. (Read: The Problem is limited to this
one Executable. Phew! ;-) If running as root, its hardcoded
rsh Implementation will identify the dump'ing User as
SomeUser@SomeHost, rather than root@SomeHost. Possibilities:
1) Live with the "strange" .rhosts (which I'll do right now)
2) Run dump as non-root (involves chown'ing raw Disk Devices ...)
3) Patch 102680-04 might fix it (I'll check)
4) Avoid the ufsdump rsh Implementation altogether (like in
dump f - | rsh dumphost cpio or whatever. I'ld like to
get ufsdump switched to ssh, but that's a Bit too messy
to do it from Scratch myself ;-)
