Something is closing your ssh session, What dist are you using? Verify that Shorewall and iptables havent blocked something. Try to shutdown iptables and shorewall and see if it workes better from /etc/init.d....

With iptables -L you can see if any chains are implemented on your system.

Is your sshd running?

Have you changed de IP addresses after previous connections?

Se and clean your .ssh/known_hosts...

Just a guess...

[stathisx]

i haven't changed my ip's (for both pc's).and of course sshd is running ..i figured it out with

ps -elf|grep sshd

do i have to edit some kind of files i found in /etc/ssh?
this is how my /etc/ssh/ssh_config file looks like:

# $OpenBSD: ssh_config,v 1.19 2003/08/13 08:46:31 markus Exp $

# This is the ssh client system-wide configuration file. See
# ssh_config(5) for more information. This file provides defaults for
# users, and the values can be changed in per-user configuration files
# or on the command line.

# Configuration data is parsed as follows:
# 1. command line options
# 2. user-specific file
# 3. system-wide file
# Any configuration value is only changed the first time it is set.
# Thus, host-specific definitions should be at the beginning of the
# configuration file, and defaults at the end.

# Site-wide defaults for various options

Host *
# ForwardAgent no
# ForwardX11 no

# If you do not trust your remote host (or its administrator), you
# should not forward X11 connections to your local X11-display for
# security reasons: Someone stealing the authentification data on the
# remote side (the "spoofed" X-server by the remote sshd) can read your
# keystrokes as you type, just like any other X11 client could do.
# Set this to "no" here for global effect or in your own ~/.ssh/config
# file if you want to have the remote X11 authentification data to
# expire after two minutes after remote login.
#ForwardX11Trusted no


# RhostsRSAAuthentication no
# RSAAuthentication yes
# PasswordAuthentication yes
# HostbasedAuthentication no
# BatchMode no
# CheckHostIP yes
# AddressFamily any
# ConnectTimeout 0
# StrictHostKeyChecking ask
# IdentityFile ~/.ssh/identity

# GSSAPIAuthentication no
# GSSAPICleanupCredentials no

# Set this to 'yes' to enable support for the deprecated 'gssapi' authentication
# mechanism to OpenSSH 3.8p1. The newer 'gssapi-with-mic' mechanism is included
# in this release. The use of 'gssapi' is deprecated due to the presence of
# potential man-in-the-middle attacks, which 'gssapi-with-mic' is not susceptible to.
# GSSAPIEnableMITMAttack no

is there something wrong?

if you are trying to ssh as root, you need to turn that option on in /etc/ssh/sshd_config

there is a great manpage on sshd's config..
