What does 'syslogd -R 255.255.255.255' do?

    I'm trying to find the syslog on my router that runs embedded linux using BusyBox v1.00-pre2 (2005.11.11-01:19+0000) Built-in shell (msh).

    logread does output the log. But I can't figure out how to access it directly or add messages to it?

    ps shows...
    syslogd -R 255.255.255.255

    Let me know if I need to post more info to explain!

    Thanks,
    LK.

    You're looking for the log file(s) or the syslog config file?

    The syslog config file is, I read, in /etc/sysconfig/syslogd.conf, in busybox. Within this you'll find to which log files the various messages are sent.

    You mention adding entries to the log. By what means do you plan to do this. Doesn't sound like you're planning to use the system logging library.

    Which ever log 'logread' refers to...

    Sysconfig directory doesn't exist.:(

    I was hoping to put something like: echo "Hello world" >> log

    Any ideas?

    The -R option is not documented in the syslogd man page I have here but my wireless router is configured to forward syslog messages to a remote server and the process list contains /sbin/syslogd -R 192.168.1.6. Therefore, I'd guess your syslogd is configured to forward messages to the broadcast address 255.255.255.255.

    Before I enabled remote logging, messages were logged to /var/log/messages
    As ressem points out, the syslog config file determines where various types of messages are sent.

    To add your own syslog entries, you can write some RFC3164-compliant code to talk to UDP port 514 or use the logger utility which is likely already on your router (its on mine). 
    BusyBox v1.00 (2005.04.21-17:30+0000) multi-call binary

Usage: logger [OPTION]... [MESSAGE]

Write MESSAGE to the system log.  If MESSAGE is omitted, log stdin.
