SSH password-less login issue between linux and solaris

Hello Gurus,

I am trying to set up bidirectional password-less login between a linux and a Solaris. The way I am doing is very simple, which is creating pub/priv key pairs on each host and add the pub key to each other's authorized_keys file:
ssh-keygen -t rsa (I tried dsa, and it didn't work aslo)

Surprisingly enough, having done the same set up on both machines, only linux->solaris trusted connection works while solaris->linux does not Smilie

Here is the verbose logs I got when I try to ssh to linux from the solaris:

Code:
debug1: Next authentication method: publickey
debug1: Trying private key: /home/nyfcgstg/.ssh/identity
debug3: no such identity: /home/nyfcgstg/.ssh/identity
debug1: Offering public key: /home/nyfcgstg/.ssh/id_rsa
debug3: send_pubkey_test
debug2: we sent a publickey packet, wait for reply
debug1: Server accepts key: pkalg ssh-rsa blen 149
debug2: input_userauth_pk_ok: fp 80:58:a9:ba:b7:f8:5d:21:16:bd:4c:f8:d1:e0:04:dc
debug3: sign_and_send_pubkey
debug1: read PEM private key done: type RSA
Connection closed by xx.xx.xx.xxx
debug1: Calling cleanup 0x41afc(0x0)

After reading the private key the connection just closed by the Solaris.
The same pub key of linux is accepted by other Linux boxes so I am thinking this can be a cross-platform issue?

Open ssh on Linux: OpenSSH_5.2p1_q1.g463c730, OpenSSL 0.9.8k 25 Mar 2009
Open ssh on Solaris:OpenSSH_3.7.1p2, SSH protocols 1.5/2.0, OpenSSL 0.9.7c 30 Sep 2003

Any pointers will be appreciated.

Aaron

SSH-COPY-ID(1)						      General Commands Manual						    SSH-COPY-ID(1)

NAME
ssh-copy-id - install your public key in a remote machine's authorized_keys SYNOPSIS
ssh-copy-id [-i [identity_file]] [user@]machine DESCRIPTION
ssh-copy-id is a script that uses ssh to log into a remote machine (presumably using a login password, so password authentication should be enabled, unless you've done some clever use of multiple identities) It also changes the permissions of the remote user's home, ~/.ssh, and ~/.ssh/authorized_keys to remove group writability (which would oth- erwise prevent you from logging in, if the remote sshd has StrictModes set in its configuration). If the -i option is given then the identity file (defaults to ~/.ssh/id_rsa.pub) is used, regardless of whether there are any keys in your ssh-agent. Otherwise, if this: ssh-add -L provides any output, it uses that in preference to the identity file. If the -i option is used, or the ssh-add produced no output, then it uses the contents of the identity file. Once it has one or more fin- gerprints (by whatever means) it uses ssh to append them to ~/.ssh/authorized_keys on the remote machine (creating the file, and directory, if necessary) SEE ALSO
