rc files

This page contains some configuration (rc) files for various programs. They provide default settings and functionality. For example, the vimrc file turns syntax highlighting on by default and specifies the colour scheme.

These have slowly developed through additions from various lab members, so if you have something that you think would be a useful addition, consider adding it!

Of course, how you configure your programs comes down to personal preference, so feel free to modify however you wish.

ssh/config

Adding the following lines to ~/.ssh/config will improve the user-friendliness of shelling into remote servers, especially if you do it often.

For example, using the config settings below you can simply use ssh graham instead of ssh <userid>@graham.computecanada.ca. Additionally, the ServerAliveInterval helps to maintain the server connection, even if your inactive for a while. Setting the ForwardX11 flag sets whether or not X11 forwarding (the -X flag) should be used by default.

# COMPUTE CANADA hosts
Host graham orca
    HostName %h.computecanada.ca
    ServerAliveInterval 540
    ForwardX11 no

# Private MATH hosts
Host bow minnewanka waterton
    HostName %h.math.private.uwaterloo.ca
    ServerAliveInterval 540
    ForwardX11 yes

# MATH hosts
Host boogaloo hood
    HostName %h.math.uwaterloo.ca
    ServerAliveInterval 540
    ForwardX11 no
