Yes, but there's always a chance that something goes wrong. If you can't take any change then don't update. You don't have a secondary procution server, but do you have a secondary computer? If so use this a test server. (Go for the most identical one) Install 4.3 on this one and then update this one, using the same source. Also set it up to sepport the most critical functions. This not only gives you the change to gain some experinace but also let you test it. You won't upgrade the production computer if this fails. ( On later version (4.6 or 4.7) you could let your production computer compile the source and use its /usr/src/ and /usr/obj/ through nfs. ) You wan't to backup /etc/ /usr/local/etc/ and you data. -- Alex Articles based on solutions that I use: http://www.kruijff.org/alex/index.php?dir=docs/FreeBSD/ ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

There *is* no way to have such a comprehensive list that would be accurate for everybody. You need all of the locally-modified files, which can include nearly anything in /etc, most of /var, locally created data (including user directories, but possibly many other things, like a web server root, as well), tuning files for ports, and on and on. If in doubt, the best thing is to back up the *entire* system and you know you'll have a backup of anything you need. You don't need to worry too much about what to merge, because mergemaster takes care of finding the normal system configuration files and helping you merge them -- but you need to know how the system is set up, and how you *want* it to be set up. > However, I upgraded that machine and all works fine (finally the sendmail, > too).

Is it I have misconfigured pam ? And how can I repair it ? Sure looks like a PAM misconfiguration. The configuration is /etc/pam.conf and the default file is /usr/src/etc/pam.conf and unless you have intentional configuration changes, they should probably be identical. mergemaster(8) should have caught that for you. ___ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to "[EMAIL PROTECTED]"

Many thanks to everybody. Of course, I have read the Handbook, but there are very "wide" solution, not so specific as I tried to find.

Well, the safest approach is to have a spare system, and build the modifications on that. If you can't do that, then almost as safe (and actually safer from your own oversights) is to have a spare machine to try out the upgrade on so you get used to the procedure. If you really can't spare a machine for any of these things, accept some downtime and make sure you're *very* careful as you go through the documented procedure. > Please, advice if you have some know-how :-))) All of my specific advice is *in* the Handbook.

I reckon you have not even bothered to read the docs available at the FreeBSD website nor the information that is generally available on the system itself.
