Remote logging with Linksys WRT54G

November 1st, 2005

Enabling remote syslog logging with Linksys WRT54G and OpenWRT White Russian RC3 is as simple as storing the IP of the remote syslog server into the log_ipaddr NVRAM variable:

nvram set log_ipaddr=A.B.C.D
nvram commit
reboot

log_ipaddr is used by /etc/init.d/rcS startup script to launch a local syslog daemon with option “-R “:

#!/bin/sh
syslog_ip=$(nvram get log_ipaddr)
ipcalc -s "$syslog_ip" || syslog_ip=""
syslogd -C 16 ${syslog_ip:+-L -R $syslog_ip}
klogd
...

    I’m impressed, I must say. Really rarely do I encounter a blog that’s both educative and entertaining, and let me inform you, you’ve gotten hit the nail on the head. Your idea is outstanding; the problem is one thing that not sufficient individuals are speaking intelligently about. I’m very happy that I stumbled across this in my search for something referring to this.
