Customizing LOG output

Customizing LOG output

[Josh Larocque]

Is there a way to change the data the the LOG module outputs?  As it stands right now it's printing IN, OUT, MAC, SRC, DST, LEN, TOS, PREC, TTL, ID, PROTO, SPT, DPT WINDOW, RES and UGRP... all taking up about 2 and a half lines on the screen for each entry. I'd like to get it down to a one-liner if possible.

Thanks,

Josh

Yes, hack at net/ipv4/netfilter/ipt_LOG.c by editing those printk's.

Don't forget to recompile this module and also rmmod ipt_LOG.

You can also give a try to ULOG, it logs to databases,
plain files, syslog formats, etc. It could be a lot
easier to modify ULOG than the iptables o Netfilter code.
