syslog configuration

David Logan_2 — Wed, 21 May 2003 02:26:59 GMT

Hi Folks,

I have a small problem with the syslog configuration on a V4.0F system.

I wish to use the cron facility so I have the syslog.conf configured :

kern.debug /var/adm/syslog.dated/kern.log
user.debug /var/adm/syslog.dated/user.log
mail.debug /var/adm/syslog.dated/mail.log
daemon.debug /var/adm/syslog.dated/daemon.log
auth.debug /var/adm/syslog.dated/auth.log
syslog.debug /var/adm/syslog.dated/syslog.log
#lpr.debug /var/adm/syslog.dated/lpr.log
lpr.info /var/adm/syslog.dated/lpr.log

msgbuf.err /var/adm/crash/msgbuf.savecore

kern.debug /var/adm/messages
kern.debug /dev/console
cron.warning /var/adm/syslog.dated/cron.log
*.emerg *

I HUP syslog and no messages appear. To test my new facility (cron.warning) I have tried to use the logger command thus :

logger -pcron.debug 'this is a test message from logger'

I receive the following error message
logger: unknown facility name: cron

As cron is mentioned in both the man pages for logger and also in /usr/include/sys/syslog_pri.h can anybody explain why this isn't working?

Have I configured something incorrectly? or using it incorrectly?

The file /var/adm/syslog.dated/cron.log has been created and has perms -rw-r-----

Thanks

Try

# logger -p 72 4

the log directory is specified as /var/adm/syslog.dated/cron.log, but the file should be within /var/adm/syslog.dated/current/

stop and restart the syslog daemon to be sure the new configuration will be used.

Ralf,

I posted a question with subject: Message when someone su root.

I tried to configure syslog but I received the same errors of David Logan with the difference that logger gives me answers and it writes on log files.

This is my .conf:

kern.debug /var/adm/syslog.dated/current/kern.log
user.debug /var/adm/syslog.dated/current/user.log
mail.debug /var/adm/syslog.dated/current/mail.log
daemon.debug /var/adm/syslog.dated/current/daemon.log
auth.notice /var/adm/syslog.dated/current/auth.log
syslog.debug /var/adm/syslog.dated/current/syslog.log
lpr.debug /var/adm/syslog.dated/current/lpr.log

msgbuf.err /var/adm/crash/msgbuf.savecore

kern.debug /var/adm/messages
kern.debug /dev/console
*.emerg *

Thanks in advance.
Ezra

Hi,

Maybe I didn't understood the problem correctly.
Anyway, the cron facility doesn't seem to be available in the source of logger.c
So, the errormessage is rather normal.

As workaround, I suggest to use following line in /etc/syslog.conf

local1.warning /var/adm/syslog.dated/cron.log

Now the command
# logger -plocal1.warning "This works fine"
will generate the expected output in /var/adm/syslog.dated/current/cron.log

If local1 is already used, you can use another facility from local[0-7]

Maybe it's helpful

I tried your settings but when I restarted syslog the old entries were disapeared and there was the new one cron.log.

logger string worked.

I still don't understand.

Thanks a lot Joris

Ezra,

Your old entries are not gone.
When the -HUP signal is send to the syslogd it will create a new date-directory an make a symbolic link to the "current" directory.

here you see a part of /var/adm/syslog.dated.

drwxr-xr-x 2 root adm 8192 Jun 12 12:15 12-Jun-12:15
drwxr-xr-x 2 root adm 8192 Jun 13 12:15 13-Jun-12:15
drwxr-xr-x 2 root adm 8192 Jun 13 16:11 13-Jun-16:11
drwxr-xr-x 2 root adm 8192 Jun 13 16:27 13-Jun-16:27
lrwxr-xr-x 1 root adm 12 Jun 13 16:27 current -> 13-Jun-16:27

You can see that syslogd as been -HUPped at 16:27 and just before at 16:21.

So, you will find your old entries in the directory that has been created before the one that is "symlinked" to current.
