Re: ssh with shared home dir

hmm.. ok then gordon thanks for the input! how do these permissions grab ya?


[bluethundr@LCENT01 ~]$ ls -alh | grep .ssh
-rw-------   1 bluethundr summitnjops    70 Oct 17 14:04 .lesshst
drwx------   2 bluethundr summitnjops   512 Oct 22 14:06 .ssh


[bluethundr@LCENT01 ~]$ ls -lah .ssh
total 34K
drwx------   2 bluethundr summitnjops  512 Oct 22 14:06 .
drwx------ 106 bluethundr summitnjops 5.5K Oct 22 14:44 ..
-rw-------   1 bluethundr summitnjops  820 Oct 22 14:19 authorized_keys
-rw-------   1 bluethundr summitnjops 1.7K Oct 22 14:18 id_rsa
-rw-r--r--   1 bluethundr summitnjops  403 Oct 22 14:18 id_rsa.pub
-rw-r--r--   1 bluethundr summitnjops  20K Oct 22 14:47 known_hosts
[bluethundr@LCENT01 ~]$


as is stands, currently, still not working!

this is what it looks like when I ssh to another host that shares this
home directory (and .ssh dir) as the one I am ssh'ing from.

[bluethundr@LCENT01 ~]$ ssh virt1
bluethundr@virt1's password:

I've posted a -vvv version of the ssh session in an attachment.

thanks!
