This is the CVS info page for the Panda project. Note: The Panda CVS Repository has been moved from BNL to CERN, so please DO NOT use the BNL repository anymore! Start using the CERN repository immediately.


Instructions on how to use the CERN ATLAS CVS Repository are at and the repository can be browsed at or at the LXR Cross Referencer at

You can find more info on the CERN CVS server at (second to last item).

For SSH access

  • CVS_RSH=ssh
  • CVSROOT=:ext: your_cern_username
  • project name: offline/Production/panda
your_cern_username above is your CERN account. During execution you will be asked for the password. Unless you set up ssh keys; you can find information on how to do this at

For kserver access

  • CVSROOT=:kserver: your_cern_username
  • CVS_RSH must NOT be set
  • You will need a kerberos4 ticket:
  • klog.krb -pr your_cern_username -c
  • Your machine will need the following entries in the krb files:
  • /etc/krb.conf:

  • /etc/krb.realms: CERN.CH CERN.CH

  • Your firewall needs to have port 750/udp (and most likely 88/udp as well ) open for INCOMING connections
  • Be aware that you can only use EITHER ssh OR kserver access methods, but you can NEVER switch back and forth once you have checked something out of the repository for the first time with one method! (Unless you know what you are doing and override $CVSROOT with the -d switch on the command line.)

BNL CVS Area (obsolete - readonly and no longer updated!)

This area is now readonly and contains a snapshot of the project as of 9/28/2005. Check-in should be impossible and do not use it for checkouts or updates because you will get stale files. Use the CERN area above.

The Panda CVS area is on the BNL CVS server at


and can be browsed with its web interface at or at the LXR Cross Referencer at

To access it, you need a BNL AFS token and set


and AFS access, of course.

You can find more info on the USATLAS CVS server at

cvs add: use 'cvs commit' to add this file permanently
acas0008:~/panda $ cvs commit -m "initial commit"
cvs commit: Examining .
