The Purple Cow:
sysadmin central
As a professional geek and system administrator, I've written a lot of
quaint little programs to help me along the way. And now I am sharing them
to the world. They are simple scripts, and hopefully you'll find them
useful. Most should work for most any Unix OS (BSD, Solaris, SunOS,
Linux).
Enjoy!

Shell Scripts
| name |
shell |
description |
|---|
|
codez |
perl |
Command-line web scraping tool which allows you to quickly search for information on area codes, phone numbers, zip
codes, and even get all the zip codes for a given city. Only good for US zip codes and phone numbers. Uses USPS.com and MelissaData.com.
|
|
syslogmailer |
sh |
This shell script sends a given user a day's output of the syslog.
Originally written for Solaris, it will probably work most
anywhere.
|
|
mlogmailer |
ksh |
Based on syslogmailer, mails out a defined set of logs to a user
for the previous day. Finds problems before you realize them.
|
|
adduser |
ksh |
Uses Solaris' useradd program to add users. Makes adding users
fun!
|
|
fw-1-pager |
ksh |
Takes input from a CheckPoint FireWall FW-1 formatted accept/deny
message, formats it does error checking, then pages, mails, or logs the
accept/deny. Used mostly for denies, so the sysadmin is paged or
e-mailed where the deny was from. Useful if the box is comprimised and
logs are modified.
|
|
check_load |
ksh |
Using uptime, awk, top, and mail, this script checks the load on
the box, and based on a scale, either pages or mails the specified
people.
|
C Programs
wtmpxcut.c
wtmpxcut binary for Solaris 2.6 |
C program |
When I saw that /var/adm was being taken over by a 9MB wtmpx file,
I looked for a wtmpx trimmer. I found this. I took it, translated
it from French to english, made it more friendly by adding command
line options, intuitive error messages, some buffer overflow
precautions, and tested it on two Solaris platforms. I like it.
