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
...
