This is the chapter of the MemberManual that describes how to log in to our machines, and provides a brief explanation of what our machines do.
Only ssh.hcoop.net is accessible to members. To login, use SSH where
- Your HCoop username
- host key fingerprint
GNU/Linux, OS X, BSD
Open a shell and run:
We have some security restrictions in place on the shell servers designed to thwart would-be attackers. Basic http, irc to trusted networks, etc. work by default, and we liberally grant requests for additional network permissions (See FirewallRules).
Our shell server is running a basic installation of Debian Stretch. You may find that all of the software you need is already installed, but if not you may request installation of packages available in stretch and stretch-backports.
Software not provided by Debian may be manually installed somewhere like ~/local/ in your home directory.
Changing Your Password
On your first login, and thereafter on some regular basis (quarterly is generally alright), you should change your password. To do this, login to the shell server and run
It will prompt for your current password and your new password twice.
(We use kpasswd instead of the standard UNIX passwd because of an unfortunate interaction between MitKerberos and Debian's default PAM configuration).
Changing the Default Shell
If you wish to change your login shell, then create a symlink called ~/.loginshell whose target is your shell of choice. Here is one example:
ln -sf /bin/zsh ~/.loginshell
Resetting you bash profile
If you wish to change your bash profile, the template file is called /etc/skel/.profile, which should be on any accessible member machine.
This directory is where the default files are kept, and they are copied to each user's home directory when user is created.
Our file is just a stock/basic version with no HCoop-specific customizations.
