4.7, syslogd and remote router logging

4.7, syslogd and remote router logging

Post by Mike Tod » Tue, 10 Dec 2002 17:48:18



I setup a FreeBSD 4.7 server to be a syslog server for a network with nodes
around the globe.  We started with a test to collect syslog messages from
just one router in the Middle East.  We entered the following line in the
syslog.conf file:

local5.debug    /var/log/router.log

and started syslogd using the following command:

/usr/sbin/syslogd -a 10.10.10.2

No logging occurred even though the documentation for syslogd indicates this
is the way to collect log entries from a remote system.

Since the -s option (to disable logging from external sources) is the
default, we entered syslogd_flags="" in the rc.conf file.

It still did not log the entries from the remote.

When we removed the "-a 10.10.10.2" from the command to start the syslogd
service it started working.  However, we had to shut down syslogd and
restart it before it would work.  kill -HUP 'cat /var/run/syslog.pid' would
not restart syslogd in a working state.  The only way was to kill syslogd
completely and start it without command line parameters.

At that point the logging started immediately.

Summary:

1. Enter services to be logged in the syslog.conf file.

2. Override the "-s" option in /etc/default/rc.conf by entering
syslogd_flags-"" in the /etc/rc.conf file.

3. Start /usr/sbin/syslogd without command line parameters.

This works.

1. syslogd got me stumped (trying to log Cisco router messages)

I am using Slackware version 1.2.13 and can't configure the syslogd to
accept messages from my Cisco router. I believe my Cisco is configured
correctly to relay messages to the IP address of my Linux box. I have also
checked network connectivity and all seems fine.

One problem I am having is finding documentation that does more that simply
mention that syslogd exists. I did look up the on-line help on syslog.config
but did not have much luck with it. Here are some specific questions:

1) Is there more thorough documentation somewhere that explains syslog in
detail?

2) Does syslogd have it's own process or is it part of inetd? I only see
inetd when I use the ps command.

3) Is there a way to manually send a message to syslog to see if it is
working? By the way, the messages in my /var/adm/syslog seem to be old - not
logging anything new.

4) Does anyone have a Cisco configured to log to Linux? The Cisco doc
recommends the following modification to the syslog.config file:

     local7.debug                                    /var/adm/router.log

I have made this change but the /var/adm/router.log file was not created,
even though I had debug level trapping enabled on the Cisco. I then used the
touch command to create this file, in case it needed it to start logging to
it. Nothing. The file stays at 0 bytes.

Would appreciate some pointers.
