using remote cvs on wendy

We assume that

• the repository is in ~se4/cvsroot (on wendy), and that
• the user dvermeir@tinfpc2.vub.ac.be is to be given remote access to the repository. Note that dvermeir is the user name and tinfpc2.vub.ac.be is the name of the remote machine.
• the remote machine (tinfpc2.vub.ac.be in the examle) can reach the appropriate port on wendy. This is the case for machines in the vub.ac.be domain but not for others. From outside vub.ac.be, you can still use cvs but then you need to use ssh (with identity files) and set CVS_RSH=/usr/local/bin/ssh, but that is outside of the scope of this note, see e.g. getting started with ssh or ssh setup.

1. Get rsh working from tinfpc2.vub.ac.be to wendy.
   1. Ensure that tinfpc2.vub.ac.be is the official hostname. This can be checked by finding out the IP address of the machine (from /etc/hosts) and then using nslookup to get the official hostname.

      	rasto$ grep 184 /etc/hosts
      	134.184.65.91           rasto.rave.org rasto
      	

      This is another name than tinfpc2!

      	rasto:~$ nslookup 134.184.65.91
      	Server:  igwe11.vub.ac.be
      	Address:  134.184.49.11
      	 
      	Name:    tinfpc2.vub.ac.be
      	Address:  134.184.65.91
      	

      So tinfpc2.vub.ac.be (not rasto.rave.org) is the official hostname of the remote machine.

   2. Update ~se4/.rhosts on wendy by addding a line

      	wendy$ echo "tinfpc2.vub.ac.be dvermeir" >>$HOME/.rhosts
      	

   3. Check that rsh works by trying to connect from tinfpc2.vub.ac.be:

      	rasto$ rsh wendy -l se4
      	Last login: Fri Feb 16 14:13:32 from tinfpc2.vub.ac.be
      	Sun Microsystems Inc.   SunOS 5.7       Generic October 1998
      	1 WEndy:~$
      	

      (This command should log you into wendy without asking for a password).

2. On tinfpc2.vub.ac.be: define CVSROOT to refer to the repository on wendy. E.g. you can add the line

   	export CVSROOT=:ext:se4@wendy.vub.ac.be:/export/home3/students/se4/cvsroot
   	

   to your .bash_profile file.

3. Test it.

   	rasto:~$ cvs co test
   	cvs server: Updating test
   	U test/test.C
   	rasto:~$
