[PLUG] ssh passwordless login

[Daniel Herrington]

All,

I'm stuck with a ssh passwordless login problem. Source machine is a
solaris 10 box behind a firewall and NAT. The remote machine is Mint 13
behind firewall and NAT.

Source:
debug1: using hostkeyalias: XXXXX
debug3: check_host_in_hostfile: filename /u/XXX/.ssh/known_hosts
debug3: check_host_in_hostfile: match line 2
debug3: check_host_in_hostfile: filename /u/XXX/.ssh/known_hosts

XXXXX at XXXXXXX.com's password:

Remote sshd log:
Oct 20 13:36:56 XXXX sshd[31134]: Connection from ###.###.###.## port 12996
Oct 20 13:36:58 XXXX sshd[31134]: Failed publickey for XXX from
###.###.###.## port 12996 ssh2

This works from an internal Mac to the Mint machine with the same
id_rsa.pub (I copied it over to the Solaris machine by using scp. Directory
permissions:

drwxr-xr-x   2 XX XXX    1024 Oct 20 16:34 .
drwxr-xr-x   5 XX X        1024 Oct 20 14:21 ..
-rw-r--r--   1 XX XXX     392 Oct 20 15:47 authorized_keys
-rw-------   1 XX XXX     392 Oct 20 15:35 authorized_keys.old
-rw-r--r--   1 XX XXX     246 Oct 20 16:35 config
-rw-r--r--   1 XX XXX     392 Oct 20 15:21 id_rsa
-rw-r--r--   1 XX XXX     392 Oct 20 16:34 id_rsa.pub
-rw-r--r--   1 XX XXX     805 Oct 20 15:12 known_hosts

At this point I don't know where to look further. Is there a higher level
of debug on sshd other than VERBOSE?

The fact that it works from the Mac to ubuntu but not from Saolris to
ubuntu, it seems to be something on the solaris machine...
