Hello Experts

I have configured my router to send syslog messages to my server, however without issuing the command logging source-interface xxxx the the syslog server won't see any syslog messages.

Is there any explanation why?

Cheers

Carlton

If your syslog server is firewalled and your cisco router has multiple IPs, the IP originating the syslog packets may not be in the firewall list of allowed tcp/udp port 514.

Have you run wireshark on the syslog server to determine the originating IP

Jesper,

I have disabled the firewall. I do have other interfaces on the syslog server but they are either disconnected or disabled.

I will run wireshark and post the results

Any other suggestions?

Do you have more than one IP address on the router?  I suspect that the syslog packets are not originating from the IP that you want them to.

my typical logging config is:

Sample:                                                           Example:

logging buffered <#>                                      logging buffered 32768
no logging console                                          no logging console
logging facility local<#>                                  logging facility local6
logging source-interface <interface>              logging source-interface Vlan1
logging <IP>                                                    logging 10.44.96.142
                                                                       logging 10.44.108.79

Your syslog data from the router may be originating from one of the other IP addresses on the router.  Specifying it is usually necessary.

Please post either your "syslog.conf" or "rsyslog.conf" and the "/etc/sysconfig/*syslog* file.

Also post "iptables --list -n"

And, I'd like to see a "netstat -an | grep 514"

One little detail:  one the router,

logging on

Then do a "show log" and post the log data minus the actual detail.

Jesper, thanks again for getting back to me. The server is Windows 7, not unix.
