| − | # Install Fedora in the typical fashion, skipping the steps for creating a default user and network authentication
| |
| − | ## When configuring network authentication, check LDAP configuration, and download the certificate from http://nuclear.unh.edu/~maurik/unh_physics_ca.crt
| |
| − | # Log in as root
| |
| − | # Disable NetworkManager if it hasn't already been disabled. (hint: chkconfig)
| |
| − | # Run system-config-network
| |
| − | # If there isn't one already, add an ethernet device on eth0.
| |
| − | # If this client is not in the server room (and therefore not going to use a VLAN), skip to the next full step
| |
| − | ## Choose to statically set the IP address to an available local number (10.0.0.*)
| |
| − | ## Give the device the alias "farm".
| |
| − | ## Make sure it has onboot=yes so that it automatically comes up
| |
| − | ## Run <code>vconfig add eth0 2</code> to create a virtual device "eth0.2" while the network is up. Might need to run <code>ifup eth0</code>.
| |
| − | ## Use system-config-network to add an ethernet device to eth0.2
| |
| − | # Alias it "unh"
| |
| − | # Make sure it has onboot=yes in the so that it automatically comes up
| |
| − | # Choose to statically set the IP address to whatever was registered for the client
| |
| − | # Set the gateway to 132.177.88.1
| |
| − | # Under the general network configuration "DNS" tab, put the appropriate IPs of einstein and roentgen for primary and secondary DNS (local for farm as the primary connection, unh for unh as the primary connection)
| |
| − | # Save the changes made with system-config-network
| |
| − | # If a virtual device was added:
| |
| − | ## Open /etc/sysconfig/network-scripts/ifcfg-unh in a text editor
| |
| − | ## Add the line <code>VLAN=yes</code>, and save
| |
| − | # If there are any more devices already present, disable, remove or configure them as well. Whatever you do, don't leave them defaulted to DHCP mode, otherwise their existence will change /etc/resolv.conf !

| − | == Fedora 13 ==
| |
| − | | |
| − | The above instructions should work for Fedora 13 with one exception. It appears that unless NFS can do a DNS reverse lookup on a server's IP Address it will not work properly. I'm not sure why this changed from the previous version of Fedora, but what it means in practical terms is that home folders won't work correctly on Fedora 13 machines. They'll mount, but you'll have weird issues like browsers being unable to load saved profile information.
| |
| − | | |
| − | The simple fix for this is to add a line to /etc/hosts for the file server, so it should look something like this for machines in the server room:
| |
| − | | |
| − | 10.0.0.240 npghome npghome.farm.physics.unh.edu
| |
| − | | |
| − | or this for machines outside the server room:
| |
| − | | |
| − | 132.177.91.210 npghome npghome.unh.edu
| |
| − | | |
| − | | |
| − | It doesn't appear that there are problems with any of the other NFS mounts, but they haven't been tested extensively either. This is an issue we should watch if we begin upgrading workstations to Fedora 13.

| − | == Ubuntu 9.04 Howto ==
| |
| − | | |
| − | It's best to not use Ubuntu 9.04 at this time. There are issues with binding as an anonymous user for password authentication. Autofs and getent password work fine with the following instructions, but without password authentication, the workstation is useless. If we were willing to set up a proxy user for ldap searching purposes, we could use Ubuntu, but I'm currently unwilling to do this, as I feel it's a security risk.
| |
| − | | |
| − | * Install as usual, making a user called "localuser" with the root password. We'll be deleting this account later.
| |
| − | * Log in as localuser
| |
| − | * System > Preferences > Network Connections
| |
| − | ** Delete the connection "auto eth0"
| |
| − | ** Add a connection, name it "unh", set the appropriate manual IP.
| |
| − | * sudo apt-get update
| |
| − | * sudo apt-get install libpam-ldap libnss-ldapd libnss-ldapd nss-updatedb libnss-db ldap-auth-client ldap-utils
| |
| − | ** When asked, set the following:
| |
| − | ldap://einstein.unh.edu
| |
| − | dc=physics,dc=unh,dc=edu
| |
| − | on services, check off passwd, shadow, groups.
| |
| − | say no to making root the database admin
| |
| − | * cd /etc/ssl/certs
| |
| − | * wget http://nuclear.unh.edu/~maurik/unh_physics_ca.crt

| − | * sudo apt-get install autofs nfs-common
