BuddyAll is a command line tool to add all users of a jabberd 1.x server to each others buddy list. Can be run as many times as you like as new users are added. Gunzip this script and put it in /var/spool/jabberd/[YOURDOMAIN]/ then run it as root to rewrite each user file. Note that the server keeps copies in RAM, which are flushed back to the files when the daemon is stopped. This means you must stop jabberd before running BuddyALL and then restart it again.
