What else do I need to do, >pray tell? It's not that easy, unfortunately. It's a system-wide limit that's compiled in when the system is built and you have to re-compile everything to change it. If you want to do this, you'll need the whole of the src distribution (not just the kernel) and change the line in /usr/include/utmp.h which says #define UT_NAMESIZE 8 Then do 'make world' in /usr/src, build a new kernel and reboot. (NB the limit is set at 8 to be compatible with NIS. If you increase it, you won't be able to use NIS any more. If you don't know what that means, you probably aren't using it 8-) >I'm starting a new FreeBSD-powered WebSite and would like to be able to >bypass this limit. If you just want to do this to get long usernames in email addresses, a much simpler way is to set up mail aliases. For example, if you use sendmail, adding a line in /etc/aliases like averylongusernameindeed: someone and doing 'mkaliases' will result in mail addressed to 'averylongusernameindeed' being sent to someone's mailbox instead. -- James Raynard, Edinburgh, Scotland jraynard@dial.pipex.com james@jraynard.demon.co.uk
