See your /etc/syslog.conf file for actual 106# path names of logfiles. The tutorial section in the README file 107# gives a brief introduction to the syslog daemon. 108# 109# Change the FACILITY definition below if you disagree with the default 110# disposition. Some syslog versions (including Ultrix 4.x) do not provide 111# this flexibility. 112# 113# If nothing shows up on your system, it may be that the syslog records 114# are sent to a dedicated loghost. It may also be that no syslog daemon 115# is running at all. The README file gives pointers to surrogate syslog 116# implementations for systems that have no syslog library routines or 117# no syslog daemons.
