I've recently attempted to move my /var directory form the root filesystem to a new filesystem I created on my hardrive, unfortunately I neglected to command "cp" to preserve the files' ownerships while copying the files form the old /var directory.
While most things seem to be working fine with this (mosf of the files were seem to have been owned by root:staff anyway) some things dont:
1. Exim - I managed to get it to work by chownning the /var/log/mail and /var/spool/mail to mail:adm and chawning the users' spool files to be owned by the users - I hope this is the way it should be.
2. MySql - It doesn't work. it seems to be a problem with /var/run/mysqld/mysql.sock but it doesn't seem to be there, maybe I should change the directoryes permission? to what?
3. ws-imapd Seems to be working _very_ slow when accessing a user's primary spool file, can it have a problem with creating a lockfile or something?
Is there somwhere I can find a good specification to what the file permissions should be?
Is there a tool that can fix it all up for me?
Hi Barak,
I don't know the answers to your questions, but in case you're still having problems (or just want to compare for reassurance), here's some output from my laptop; it runs exim & mysql, but not uw-imap
I do run courier-imap on a different machine & it creates lockfiles as root:root in /var/run/courier
it's been a little while since I installed it anywhere, but iirc the 'tiger' package will look at all your file permissions in a security context & mail you a report (among other things). I don't know of anything that will automatically change them for you, short maybe of 'apt-get --reinstall mysql-server', etc.. though even that might respect your "custom" permissions(?)
