having more than one process write to one log
Hello, I will appreciate your advice. Is it possible and *safe* to allow two different processes (dovecot and exim) to write to one log? Better not do it? I would like to have both data in one log but... don't want to cause problems. I don't think Windows would allow it. How about FBSD?

The file is created if it does not exist. The stream is positioned at the end of the file. Subsequent writes to the file will always end up at the then current end of file, irrespective of any intervening fseek(3) or similar. Another idea is to use syslog -philip ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

Those things normally use syslog to write via the LOG_MAIL facility to /var/log/maillog. Syslog-based logging will handle logging from multiple programs to just one logfile just fine. Otherwise, you are advised to look into fsync() and flock(). Those syscalls do not necessarily work on remote filesystems, however... -- -Chuck ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to [EMAIL PROTECTED]

I would like to have both data in one log but... don't want to cause problems. I don't think Windows would allow it. How about FBSD? isnt that the default? right now i see postfix, dovecot, amavisd, etc all log to /var/log/maillog With the exception that my exim writes to /var/log/exim/mainlog which I am ok with, logs are rotated, etc. My question was whether it is ok for dovecot to join the party. Still new to FBSD and that's why I am not sure if the way I would like to set it up is OK. If it is not, then I have no problem keeping logs separate. I could direct exim's logging to /var/log/maillog (this I can do :) but then I wonder if I didn't have to edit the global crontab to take care of logs being rotated, etc.?
