To Access the DESpec SVN, you need:
  • a services account

  • a kerberos ticket
  • a svn client

How to get a services account:

Member of the Subprojects

If you would like to have write access, email Brian or Laurenz, so we can add you to the DESpec project. If you don't need write access, look at the section Anonymous SVN.


How to set up kerberos

$ mv /etc/krb5.conf /etc/krb5.conf.bak
$ cd /etc
$ wget
$ echo "host
   ForwardX11 = no
   GSSAPIAuthentication yes
   GSSAPIDelegateCredentials yes" >> ~/.ssh/config
$ kinit -f your-fnal-username
$ klist

The final klist should show your kerberos ticket and the svn can be checked out now using the svn checkout command below.

Creating a sub-project repository


  • If you have a project "fred" and a "main" repository with no identifier
    you get put in
    • /cvs/projects/fred
  • if you have a project fred and a repository identifier of "joe" you get
    • /cvs/projects/fred-joe
  • So you can do give them all identifiers, or have one (main) one without;
    or you can give the Main one an identifier...
  • If there is no "Main" repository, the Repository tab doesn't show up,
