I used the Perfect Server How To to create my SuSE 11.1 server months ago. I installed ISPConfig, then uninstalled it, but the directory structure largely remains the same. The Apache server works fine. Postfix has worked fine until a few days ago, when I "cleaned up" the /srv/www/web3 directory a little bit. I may have broken Postfix. Postfix no longer starts. Mail.err reports "postfix/master[4957]: fatal: open lock file /var/lib/postfix/master.lock: cannot open file: Permission denied". Permissions shown below (I am only showing relevant data (to my knowledge): /var/lib # ls -l drwx------ 2 postfix root ... postfix /var/lib # cd postfix /var/lib/postfix # ls -l -rw------- 2 postfix root ... master.lock I have tried changing permissions to root, all, and back to postfix as originally found, to no avail. I have tried creating a new maste.lock file (w/ touch) to no avail. I am considering a Postfix uninstall/reinstall if I can't fix this issue. Any ideas or help would be appreciated, as the uninstall & reinstall may not be as simple as I need at this time.
Deletion I renamed master.lock to bmaster.lock.orig; no joy. Postfix will not start, and the same message occurs.
SELinux & locate SELinux is disabled. "locate master.lock" result is "/etc/var/postfix/bmaster.lock.orig", my backup. There is now no master.lock file, and Postfix still will not start ("postfix status" reports that it is not running after a "postfix start" command).
Did you ever find a solution to this? EDIT: SOLVED using another thread here and some googling. Details here. I have this problem on a Debian server running ISPConfig2. (After tarring the OS, so it is not the fault of ISPConfig or anything. I verified permissions vs the server it was tarred from that is running just fine, but still no go) Postfix won't start and errors out with the master.lock permission error.
