Be aware of the following issues while editing file
/etc/syslog.conf
:
z
Comments must be on a separate line and begin with the # sign.
z
No redundant spaces are allowed after the file name.
z
The logging facility name and the information level specified in the
/etc/syslog.conf
file must be
identical to those configured on the device using the
info
-
center loghost
and
info-center source
commands; otherwise the log information may not be output properly to the log host.
Step 4: After log file
info.log
is created and file
/etc/syslog.conf
is modified, you need to issue the
following commands to display the process ID of
syslogd
, kill the
syslogd
process and then restart
syslogd
using the
–r
option to make the modified configuration take effect.
# ps -ae | grep syslogd
147
# kill -HUP 147
# syslogd -r &
After the above configurations, the system will be able to record log information into the log file.
