3. Login 1 ) If your repository were on the local machine in you would use: $ cvs -d /nfs/roc/home/cvs command -d option overrides $CVSROOT as the root of the CVS tree with the given root. 2) EXT : This is one of the access methods that can be used and is more secure than the others First set the environment variables: $ export CVS_RSH=ssh $ export CVSROOT=:ext:jrandom@thrush.eos.ubc.ca:/nfs/roc/home/cvs or $ setenv CVS_RSH ssh $ setenv CVSROOT :ext:jrandom@thrush.eos.ubc.ca:/nfs/roc/home/cvs depending on the unix shell you use. 3) Another way to do all this is to without seting the environment variables, is to specify the repository each time: $ cvs -d ":ext:jrandom@eos.ubc.ca:/nfs/roc/home/cvs" command

4. PSERVER Another access method that can be used. It stands for "password- authenticated server". Here, you have to login to the cvs server first, and then the rest is just like regular cvs routines First set the environment variable: $ export CVSROOT=:pserver:jrandom@eos.ubc.ca:/nfs/roc/home/cvs or $ setenv CVSROOT :pserver:jrandom@eos.ubc.ca:/nfs/roc/home/cvs depending on the unix shell you use Following Unix custom, cvs login returns silently if the login succeeds; it shows an error message if it fails (for instance, because the password is incorrect). $ cvs login CVS password: (enter your CVS password here)
