I am relatively new to Ubuntu. I recently installed Ubuntu Server 12.04 and am having Openssh problems. I reset the port number in the ssh_config file. when I PuTTy from my laptop to the server I must use port 22. Here is the ssh_config file that I slightly changed.



# 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 some commonly used options. For a comprehensive
# list of available options, their meanings and defaults, please see the
# ssh_config(5) man page.

Host *

# ForwardAgent no
# ForwardX11 no
# ForwardX11Trusted yes
# RhostsRSAAuthentication no
# RSAAuthentication yes
PasswordAuthentication yes
# HostbasedAuthentication no
# GSSAPIAuthentication no
# GSSAPIDelegateCredentials no
# GSSAPIKeyExchange no

# GSSAPITrustDNS no
# BatchMode no
# CheckHostIP yes
# AddressFamily any
# ConnectTimeout 0
# StrictHostKeyChecking ask
# IdentityFile ~/.ssh/identity

Port 222

# Ciphers aes128-ctr,aes192-ctr,aes256-ctr,arcfour256,arcfour128,aes128-cbc,3$
# MACs hmac-md5,hmac-sha1,umac-64@openssh.com,hmac-ripemd160
# EscapeChar ~
# Tunnel no
# TunnelDevice any:any
# PermitLocalCommand no

# ProxyCommand ssh -q -W %h:%p gateway.example.com

SendEnv LANG LC_*
HashKnownHosts yes
GSSAPIAuthentication yes
GSSAPIDelegateCredentials no
# Banner /etc/issue.net


It sure seems to me that there should be more uncommented lines in this file. I am using ubuntuserverguide.pdf as a reference. I obtained this file from the Ubuntu 12.04 web site.

Any help will be appreciated.

Did you restart the server after changing the port?

I did restart the server after I made the changes to the file.

The ssh_config file is for the client. The sshd_config file is the configuration for the server.

Look at the blue square warning at the start of the article:
https://help.ubuntu.com/community/SSH/OpenSSH/Configuring

You are editing the wrong file.
