SSH Config - Sample file to show staff the common options to add to your '~/.ssh/config' file. This is just a text file and should have the same perms as the other files in ~/.ssh, usually 600 (read and write by user only).

ssh-config

#### Example SSH config file

# Host = a list of domains, IPs and personalized aliases that use this config
# entry. These alias names follow "Host" and are space delimited.
#  e.g. Host 192.168.1.1 example.com example1 myalias1
# Hostname = the IP or real hostname
#  e.g. Hostname 192.168.1.1
# User = the username
#  e.g. User jdoe
# Port = if this is a non standard port, i.e. not 22
#  e.g. Port 2345

# The above would allow you to use 'ssh exp1' or 'ssh myalias1' which are now
# both equivalent commands for 'ssh [email protected] -p2345'

#### Example entries

# Example 1
Host 192.168.1.1 example1
  Hostname 192.168.1.1
  # Non standard port
  Port 2222
  # Enable forwarding
  ForwardAgent yes
  # Proxy forwarding of the connection via 192.168.1.3
  ProxyCommand ssh [email protected] nc %h %p 2> /dev/null

# Example 2
Host 192.168.1.2 example2
  Hostname 192.168.1.2
  # Enable forwarding
  ForwardAgent yes

  # Forward agent for pushing your ssh-agent. You will need to add your ssh key
  # to the authorized_keys file on the remote system.
  # Normally not a great idea to make this a global always on option unless you
  # are sure the remote systems are secure.
