You're right that >SSH would probably involve extra overhead such as the encryption >(at least for SSH). That is not the problem. The problem is how CVS itself works with a remote repository. If you're on machine A, and the repository is on machine B, then CVS will build a lot of information in /tmp on machine B when machine 'A' does a cvs-checkout of the entire tree. The issue is the same if you do that over 'rsh' instead of 'ssh'. I do not mind the overhead from encrypting the connection. This is not much of an issue for small repositories, but it becomes a major issue when working with a repository as large as those for freebsd src or ports. I have nearly crashed servers by doing a cvs-checkout of the freebsd repository, because the server-machine ran out of disk space. It is *much* cheaper if the server is giving out the repository via cvsup, instead of cvs clients. -- Garance Alistair Drosehn = gad@gilead.netel.rpi.edu Senior Systems Programmer or gad@freebsd.org Rensselaer Polytechnic Institute or drosih@rpi.edu
