Making your Ubuntu box Andrew-ish

This document is based on input from Making your Ubuntu or Debian box Athena-ish and Ashwin Barambe.
Here is another interesting link related to the subject : Running SuSE in the SCS environment.


Before you de-facilitize your box, copy the following files to some place from where you can copy them back to the new installation

• /etc/krb* (/etc/krb5.keytab is an important file and will contain your machine name - eg. gs6172.sp; remember to give your ubuntu box the same name later).
• /etc/openafs/*
• ~/.ssh/*

On the new Ubuntu box create a user (username same as your AndrewId).

• DHCP client
• sudo vim /etc/dhcp3/dhclient.conf
• send host-name "blah.sp.cs.cmu.edu";
• supersede domain-name "sp.cs.cmu.edu";
• sudo /etc/init.d/networking restart


• Kerberos
• apt-get install ssh-krb5 krb5-user krb4-config
• dpkg-reconfigure krb5-config krb4-config
• default Kerberos realm = CS.CMU.EDU
• default Kerberos server = kerberos.cs.cmu.edu
• Copy the backed-up krb* files into /etc (root:root)
• klist
• kinit -l 1d
• klist


• AFS
• AFS Kernel Module
• sudo apt-get install module-assistant build-essential gcc-3.4 openafs-modules-source
• sudo module-assistant prepare
• sudo module-assistant auto-install openafs-modules
• sudo depmod -a
• AFS Client
• sudo apt-get install openafs-client openafs-krb5
• sudo dpkg-reconfigure openafs-client
• CellServDB = cs.cmu.edu
• cat /etc/openafs/ThisCell, should show you, cs.cmu.edu
• Optional: copy the backed-up /etc/openafs/* files into /etc/openafs (root:root)
• sudo /etc/init.d/openafs-client force-start
• klog.afs
• tokens
• NOTE for Edgy/Feisty(?)
• Openafs 1.4.2 did not make it to Ubuntu 6.10, and the Openafs release included with 6.10 is broken.
• Use the following fix - Openafs 1.4.2 and Ubuntu


• My kinit and klogin script looks like this.

                $ cat my_kinit.sh
                #!/bin/bash -x
  
                export PATH=/usr/bin:$PATH
  
                sudo /etc/init.d/openafs-client force-start
  
                echo "Kerberos Login"
                kinit -l 1d
                klist
  
                echo "AFS Login"
                klog.afs
                klog.afs -c andrew.cmu.edu
                tokens
                



• Printing
  • use cupsys for Edgy/Feisty/Gutsy/... and add the printer manually using System-Admistration-Printing (in Gnome), click on NewPrinter, wait a while, then click on other, url => lpd://yellow.srv.cs.cmu.edu/ghc9206bw, lpd://yellow.srv.cs.cmu.edu/iron, lpd://cyan.srv.cs.cmu.edu/stone, lpd://monolith.srv.cs.cmu.edu/agate, ....
  
  
  • For printer model, name, location, etc: csd helpdesk - printing
  
  
  
  • For Dapper

                  sudo apt-get remove cupsys
                  sudo apt-get install lprng
                  cp printcap_linked /etc/printcap
                  

    (change the printer descriptions as required, i.e., add your printer lines to /etc/printcap, but make sure you add the ":force_localhost@" line ... otherwise nothing will work)
    After this, lpq, lpr and lprm will work as normal.

            1. Backup
  
                Install the backup client by following the instructions in the README in this directory.
                > afs/cs/project/operations/Backup-Client
  
                > However since this is not a facilitized machine there
                are some differences. First don't perform step 4(Editing
                inedt.conf) Ubuntu uses xinetd. Instead do the
                following:
                * Enable the terad service.
                * Open the port 1967 in the firewall (if you have one set-up).
  
                Step 5 is also different because you must comment out a
                line for port 1967 that already exists in
                /etc/services. Don't forget to email facilities and tell
                them that you have changed your distribution and that
                the location of the backup has changed.
  
  
            2. Terminal Server
  
                The setup of the terminal server is easy. Just add the following:
                > cd usr/local/bin
                > ln -s afs/cs.cmu.edu/local/rdesktop/common/scripts/004/bin/ts
