fantastic, works , thank you so much !!


Hi Don,

I tested with small samples and everything seems to work, I was wondering about the run-time of the original data.
File1 is 3.5Mb and File2 is 7.9Gb, is the code supposed to run for a long time? It has been 4 hrs, and it hasn't produced any output lines.

FIAIF-SCAN(8)					      Administration and Privileged Commands					     FIAIF-SCAN(8)

NAME
fiaif-scan - print syslog entries in human readable form SYNOPSIS
fiaif-scan [ -n ] [ -m ] DESCRIPTION
fiaif-scan reads lines from STDIN and prints to STDOUT, in human readable form, any packets found (standard syslog format is assumed). Each log message is parsed based on the configuration files at the time fiaf-scan is run. The idea is to enable the user to quickly iden- tify which zone rule is causing the packet to be logged, and how to change this, if necessary. OPTIONS
-n Don't do a reverse lookup of IP addresses or ports; display them as numbers. This reduces the number of host lookups and speeds up scanning. -m print the MAC address on each line. EXAMPLE
fiaf-scan -n </var/log/messages Scan from the current system log and display any packets on the console. Don't look up names for IP addressses or ports; just show the numbers. FILES
/etc/fiaif/fiaif.conf AUTHOR
Anders Fugmann <anders(at)fugmann.net> BUGS
The program has been tested only with messages from the standard syslog. It may work on lines from ulogd, but this has not been tested. Bash may not be the fastest parser in the world. Expect this software to be slow. (40 lines per sec on a K6-II/300Mhz without name lookups). Please report other bugs to <fiaif@fiaif.net>. SEE ALSO
