Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I am running a Mandrake 9.1 server with OpenSSH 3.6.1. I can login on the localhost but when I try to login from the internal network or from outside the internet it gives this error:
ssh_identification_exchange: Connection closed by remote host
My log files give this error:
sshd: refused connect from 193.172.*.* (193.172.*.*)
(I have replaced the last two bits of the IP with astrics so my IP-adress is not fully revealed)
I am running a firewall (shorewall) but it has port 22 open, so I don't think that that is the problem, since the problem remains when I shutdown the firewall. I can't really think of any more info at the moment which is relevant. I hope anybody can help me out with this.

# This is the sshd server system-wide configuration file. See
# sshd_config(5) for more information.
# This sshd was compiled with PATH=/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin
# The strategy used for options in the default sshd_config shipped with
# OpenSSH is to specify options with their default value where
# possible, but leave them commented. Uncommented options change a
# default value.
# rhosts authentication should not be used
# Don't read the user's ~/.rhosts and ~/.shosts files
# For this to work you will also need host keys in /etc/ssh/ssh_known_hosts
# similar for protocol version 2
# Change to yes if you don't trust ~/.ssh/known_hosts for
# RhostsRSAAuthentication and HostbasedAuthentication
# To disable tunneled clear text passwords, change to no here!
# Change to no to disable s/key passwords
# Kerberos options
# Kerberos TGT Passing only works with the AFS kaserver
# Set this to 'yes' to enable PAM keyboard-interactive authentication
# Warning: enabling this may bypass the setting of 'PasswordAuthentication'
# no default banner path
# override default of no subsystems
