Togg writes:
Syslogd wont start if remote-logging is enabled and the connection to the remote-log server is not possible on syslogd startup. I found a patch somewhere which works like a charm. It uses sendto() which seems more reliable for this issue. Please see attached patch. Many people will be more happy with this included I think. Regards, Togg
