HostA=SSH Secure Shell 2.4.0 (non-commercial version) on sparc-sun-
solaris2.8
HostB=OpenSSH_3.9p1, OpenSSL 0.9.7e 25 Oct 2004 on Linux
2.4.21-40.ELsmp
NO option to change either version.

Problem publickey authentication from HostB >> HostA does not work.

Steps so far:
1) generate clean key on HOSTA: ssh-keygen2 -P -b 1024 -t dsa /.ssh2/
hosta
2) generate clean key on HOSTB: ssh-keygen -t dsa -b 1024 -N "" -f "/
root/.ssh/$(hostname)"
3) copy HOSTA pub key to tmp file on HOSTB
4) CONVERT (on HOSTB) the tmp file on pub key from Secure Shell format
to openssh format using ssh-keygen -i (interactive after this, it
request the input file and sends converted key to stdout, which then
goes in /root/.ssh/authorized_keys2)
5) update /root/.ssh/identification file on HOSTB: echo "IdKey
" > identification

everything seems OK, until this
------------------------------------------------------
debug: Unable to open //.ssh2/identification
debug: Ssh2AuthClient/sshauthc.c:309/ssh_authc_completion_proc: Method
'publickey' disabled.

I think part of the issue is the PATH listed is that error.
Can anyone help me figure where this is coming from????
