Rez, > 1-Is it possible to switch from CVS 1.10.x to CVSNT w/o > compromising the repository structure or format? I've no idea what you mean by 'compromising'. CVSNT will automatically detect that the repository is an old CVS one and upgrade it for you as you change/commit files. If you want to force CVSNT to upgrade your whole repository then checkout the whole repository and do a 'force commit' - however that is not usually required. Once your repository is used with CVSNT there is no going back to CVS. You should be aware that CVSNT is much more secure than CVS and in particular: * the 'repository path' used in the $CVSROOT does not need to be the same as the physical path (configure in /etc/cvsnt/PServer) * the permissions/mode of checked out files does not need to match the permissions/mode of the RCS files in the repostiory * CVSNT has it's own ACL's * CVSNT can run in a chroot jail * etc > 2-Does anything special need to be done to the repository or > are both flavors of CVS able to read the repository > universally w/o any additional formatting or tweaking? The simple answer is: CVS cannot read a CVSNT repostiory. There are much more complicated answers available in the newsgroup archive. > 3-Once we switch, is there any way of going back to CVS or > switch to Subversion w/o tweaking the repository or does > CVSNT has some proprietary format and won't allow you to switch back? You can instead switch to CM Server (EVS/CVSNT 3.1) which is a single server that allows both CVS and Subversion clients. A migration utility is provided. Unless there is a measurable benefit to the organisation moving to a different SCCM tool then it is going to cost you money (ie: a negative cost/benefit). Moving from CVS to CVSNT has a low cost (since the upgrade is seamless and the CVSNT workflow a superset of the CVS workflow) however it still has costs (time, training etc) but many people find the benefits outweight those costs (eg: failsafe audit, user defined change sets, commit id's (what SVN calls 'atomic commit'), rename, merge tracking, auto merge point, access control, reliable process interlocking (lock server), support for reserved and unreserved methodologies, track and merge change not just files, etc). If some other SCCM tool provides enough benefit then the costs to migrate your existing data is largely irrelevant. > 4-The reason we're switching is because CVS via Pserver > method doesn't allow users to change their password w/o > logging into the server and the CVS user group running as > root in the background has access to all sort of things. > We're considering CVSNT because of its active directory > capabilities. Since your server will be on linux but you want AD integration you need to think carefully about what protocol to use and what configuration that requires on the server side. Our recommendations are here (got to the bottom of the page): http://march-hare.com/cvspro/security.htm Our recommendation is that from windows clients to red hat server you use the :ssh: protocol, however that will require you AD integrate your ssh authentication on red hat - this is NOT a topic for this forum, it is a red hat/ssh/winbind/pam discussion. Alternatively you can use gserver which is also very secure - but again you firstly need to get kinit working on your redhat server and that is also not a discussion for this forum (it's a kerberos/redhat discussion). Other protocol options include sspi (ntlm only on linux) and pserver (with PAM). Setting all this up is 'easy' for someone who knows what they are doing and is not CVSNT specific (but yes CVSNT has particular 'hooks' to take advantage of it once it is set up). You probably know all this already, but if you get stuck then I strongly recommend purchasing pro support (preferably from us since we are the authors), but even our pro support is limited to fixing problems with CVSNT, but 'general' authentication problems with the OS (though we do work closely with customers to help them identify those problems when we can).
