On a somewhat related note I recently discovered that the
rsh -l fred mandrake somecommand
fails when the target is a Mandrake 10.0 machine, even when "fred"
and whoever issues the command can both do rsh (via .rhosts and/or
hosts.equiv) AND when the command works as expected when sent
to a Solaris host. It failed for three different rsh
implementations (two on linux, one on Solaris) leading me
to suspect either some obscure configuration error for
in.rshd is getting in the way. Either that or the in.rshd
on this linux is broken.
The in.rshd on linux comes from: rsh-server-0.17-13mdk
Anybody else seen this?
