perl script to filter logfile
i was wondering if anyone can help me, how could i write in perl a a script that would look through a log file and print onscreen the contents of the log file excluding lines that contain '192.168.1.' and entries that contain directory paths that arent in the directory /usr/local/httpd/htdocs/ i have no expierience in perl. what i want to do is this, i want to be able to run this script to view one log file, the access_log in /var/log/httpd/ at first i would do this with 'grep -v 192.168.1. access_log that works to get rid of my internal network hits, but im tired of havintg to sift through all the people with port scanners hits on my server, most of the traffic on the site is just people running port scanners on my ip block. so if anyone can help i would apreaciate it alot, also i am thinking that this will start me off learning perl. if more info is needed i will gladly provide, thanks alot!

watchgnupg
WATCHGNUPG(1) GNU Privacy Guard WATCHGNUPG(1)
NAME
watchgnupg - Read and print logs from a socket
SYNOPSIS
watchgnupg [--force] [--verbose] socketname
DESCRIPTION
Most of the main utilities are able to write their log files to a Unix Domain socket if configured that way. watchgnupg is a simple lis-
tener for such a socket. It ameliorates the output with a time stamp and makes sure that long lines are not interspersed with log output
from other utilities. This tool is not available for Windows.
watchgnupg is commonly invoked as
watchgnupg --force ~/.gnupg/S.log
OPTIONS
watchgnupg understands these options:
--force
Delete an already existing socket file.
--tcp n
Instead of reading from a local socket, listen for connects on TCP port n.
--verbose
Enable extra informational output.
--version
Print version of the program and exit.
--help Display a brief help page and exit.
EXAMPLES
$ watchgnupg --force /home/foo/.gnupg/S.log
This waits for connections on the local socket '/home/foo/.gnupg/S.log' and shows all log entries. To make this work the option log-file
needs to be used with all modules which logs are to be shown. The value for that option must be given with a special prefix (e.g. in the
conf file):
log-file socket:///home/foo/.gnupg/S.log
For debugging purposes it is also possible to do remote logging. Take care if you use this feature because the information is send in the
clear over the network. Use this syntax in the conf files:
log-file tcp://192.168.1.1:4711
You may use any port and not just 4711 as shown above; only IP addresses are supported (v4 and v6) and no host names. You need to start
watchgnupg with the tcp option. Note that under Windows the registry entry HKCUSoftwareGNUGnuPG:DefaultLogFile can be used to change
the default log output from stderr to whatever is given by that entry. However the only useful entry is a TCP name for remote debugging.

The full documentation for this tool is maintained as a Texinfo manual. If GnuPG and the info program are properly installed at your site,
the command
info gnupg
should give you access to the complete manual including a menu structure and an index.
