AFS Access

Login

To work with the CLARAty software, you need to login into AFS. If you are at an external institution and do not have AFS, you will need to download and install AFS.

Once installed, use the klog at the command line to get an AFS authenication token. For security reasons, JPL has a policy that will expire tokens after 24 hours. You will need to login into AFS before using the system. Your system administrator can setup your local account to automatically log you into AFS if both your local account and your AFS account have the same username.

To test that you can access the JPL space in AFS, you will first need to "klog" into the domain "jpl.nasa.gov". To do so type the following:

			From Linux: /usr/local/bin/klog <afs_username>@jpl.nasa.gov
			
			From Solaris: /usr/afsws/bin/klog <afs_username>@jpl.nasa.gov

For your convenience, you can add the path for klog to your PATH variable definition. If "klog" it not in the above path, contact your system administrator. You either do not have AFS installed at your institution or it might be located in another directory.

If you are using the "tcsh", you can do so in your .cshrc file by adding the following line to your /home/jdoe/.cshrc . For Linux systems, the path is often configured to find klog. For solaris machines, you will need to add:

setenv PATH $PATH:/usr/afsws/bin

If you are at JPL, you do not need the @jpl.nasa.gov after your AFS username. If your AFS username is the same as your local username, you can also drop the username from the above command. So you can type the following:

klog

To test whether your token is valid or expired, use the following command:

tokens

Once you klogged, you can go to your JPL AFS user space:

cd /afs/jpl.nasa.gov/home/j/jdoe

To make sure you have full write permissions, try the following:

		touch test
     		rm test

Group Membership

Make sure that you are a member of the CLARAty group. To do so type:

pts membership group.claraty | grep <afs_username>

If your username is not listed, send email to claraty-help@robotics.jpl.nasa.gov to be added to the list. If you are at JPL, check that you are also a member of the subgroup claraty:jpl. Being a member of the subgroup claraty:jpl provide you access to internal JPL restricted algorithm. To check if you are a member, type:

pts membership group.claraty:jpl | grep <afs_username>

If your username is not listed request to be added to the above group.
