JIMSUN Jim's Unix and Linux Utilities [back] [home]

Here are some things I've written for my own use, enjoyment and enlightenment. In the hopes that others might find them useful, herewith I share my humble efforts. :-)

Warning: download these, don't copy-and-paste! Copy-and-paste can result in lines being unintentionally wrapped and hard-tabs being converted to spaces. Not a Good Thing.

Important: Each package you find at JIMSUN has been signed with a PGP signature. You are urged to validate any package you download by checking it against its signature. You will need Jim's PGP Public Key

You might also want to peruse my "Favorite Sites" page. There are many links there to other sites that have lots of interesting and useful utilities and applications.

Linux "Authorization Log Entry" Summarizer

authsumm.pl produces a summary of login authorization log entries for Linux systems. (I say "Linux systems." It was developed and tested on a Red Hat 5.x system. I assume they all produce the same log entries.) You feed authsumm.pl your /var/log/messages and /var/log/secure files.

FTP "Transfer Log" Summarizer

xfersumm.pl produces a summary of FTP file transfer activities for the "anonymous FTP server" included with Red Hat Linux systems. (This is wu-ftpd, is it not? Xfersumm.pl was developed and tested on a Red Hat 5.x system.) You feed it your /var/log/xferlog file.

IP Address Sorting/Counting/Whatever Utility
