Get the krb5.conf
CentOS has the Kerberos tools installed by default. So no need to install those. First we'll need the krb5.conf configuration file. We probably don't need the whole configuration prepared by the CS, but it doesn't hurt to have it around either. Let's steal the file from hulk (sorry, you'll still have to login with a password):
sudo scp your_cs_id@hulk:/etc/krb5.conf /etc/krb5.conf
If you are running as root, you can omit the sudo prefix.
Install AFS tools
In order to use the Kerberos credentials to access the AFS file system, we need to install some AFS tools. But first, add a repository with the packages of those tools:
sudo vim /etc/yum.repos.d/openafs.repo
Copy the following lines to /etc/yum.repos.d/openafs.repo:
[openafs] name=OpenAFS 1.6.1 for RHEL $releasever - $basearch baseurl=http://dl.openafs.org/dl/openafs/1.6.1/rhel-$releasever/$basearch/ enabled=1 gpgcheck=0 gpgkey=file:///etc/pki/rpm-gpg/RPM-GPG-KEY-OPENAFS priority=10
Now install the openafs-krb5 package:
sudo yum install openafs-krb5
And finally, create a configuration file for the AFS tools:
sudo mkdir /usr/vice sudo mkdir /usr/vice/etc sudo vim /usr/vice/etc/ThisCell
Copy the following line into file ThisCell:
cs.stanford.edu
Configure the SSH client
Open the SSH client configuration file:
sudo vim /etc/ssh/ssh_config
And make sure that the following is set:
Host * GSSAPIAuthentication yes GSSAPIDelegateCredentials yes GSSAPIKeyExchange yes
