1. CVS Client/Server CVS (GNU CVS) –Open source –Cross-platform Designed as a client/server application Remote access –Client cvs: uses rsh or ssh to establish a session to the remote server, issues CVS command and request –Server cvs: sends the results back to the requestor (client) –Any platform “Server” –No CVS server daemon running on a machine dedicated as CVS server !!!

2. CVS Client-Server Architecture LAVC SCS pubs SCS AFS slcsun1 SCS NFS flora NTVMSUNIX /afs/slac/g/cd/soft/cvs (repository) /afs/slac/g/cd/soft/ref (reference) /usr/local/bin/cvs esdslx02 (Linux) /usr/local/bin/cvs CVS “Server” any public UNIX machines access to AFS or/and NFS (CVS respository, reference) /usr/local/bin/cvs available slcsun1 meets such requirements in our control (easy management, security) memory consumption estimate needed a dedicated CVS server CVS Client any machines Unix, VMS, NT… CVS available an example esdslx02 (linux) /usr/local/bin/cvs rsh or ssh

3. An Example Connecting with RSH Enable RSH # cat /etc/inetd.conf shell stream tcp nowait root /usr/etc/tcpd /usr/sbin/in.rshd # cat.rhosts esdslx02.slac.stanford.edu jingchen Verify if CVS is available # which cvs /usr/local/bin/cvs No need to start a CVS server daemon! CVS repository accessible via AFS # ls /afs/slac/g/cd/soft/slaconly/cvs Connecting with SSH Disable RSH # mv.rhosts.rhosts.old Connecting with RSH Verify if rsh works # rsh -l jingchen slcsun1 'echo $PATH‘ …/u/cd/jingchen/bin:/usr/local/bin:/usr/afsws/bin… Remote CVS via rsh # cvs -d :ext:slcsun1:/afs/slac/g/cd/soft/slaconly/cvs checkout script cvs server: Updating script Connecting with SSH Verify if rsh is disabled # rsh slcsun1 ls permission denied Remote CVS via ssh # setenv CVS_RSH ssh # cvs -d :ext:slcsun1:/afs/slac/g/cd/soft/slaconly/cvs checkout script CVS Clinet : esdslx02 CVS “Server”: slcsun1

4. CVS Client on VMS Tests done: –Made SSH2 available –Enabled RSH CVS server on UNIX –No particular requirement (or setup) –access to AFS or/and NFS (CVS respository, reference) /usr/local/bin/cvs available –A test: linux (client) -> slcsun1 (server) working!!! Conclusion: –SSH no longer an issue! –Server is OK! KenB in progress “… the VMS side will work. The AFS token is another issue. We need to set up an account, if we can, that does not have a token expiration …”

5. CVS Client on NT Test with Netbean (Greg) A simple test –From NT command line (DOS) –Software: ComponentSoftware CVS for Windows –http://www.componentsoftware.com/products/cvs/http://www.componentsoftware.com/products/cvs/ –Setup and test
