Hi... I'm a total newbie on this (so maybe I won't be able to help at
all), but
what does a recon ~/host say? Probably the same, isn't it? I have tryied that,
and it's what it says when the remote machine (10.101.11.58) is off. I guess
you have checked all the advices that appear in the error message... If you're
able to run lamboot in the 10.101.11.58, I would check that an ls -la
gives the
same permissions to all the files, and that the file structure looks
reasonably
the same (I mean... that you've got a .profile with the same
permissions in the
.58 machine than in the .45 machine and so on)
I'm sorry for maybe confusing you. This is what I (a LAM ignorant) would do
Regards
