generic cgi form handler for multiple virtual hosts

form handler

This generic CGI form handler is written in python and designed to make a sysadm's life easier when dealing with multiple vhosts. Once installed, each user can create new forms completely without requiring administrator's intervention. Designed with security in mind.

try new firewall rules remotely


This is a short shell script that I use when I must edit my firewall rules remotely (the /etc/pf.conf file on OpenBSD systems). The source is well commented, or run it without args for usage info.

Inventory a Un*x System


A Bourne shell script to collect information about a host's hardware, software, and OS. Only tested on GNU/Linux (>=2.2) and OpenBSD (>=3.5). Designed to be used in the event of a system crash or when upgrading from scratch to restore the system. Includes information about the cpu's, disks, running processes, configured services, installed packages, network configuration, security configuration, and more.

Uses only standard system tools, so just drop it in root's path, chmod 755, and run. Output goes to the screen, so best used with tee to save. ssh -l root somehost or su root, then:

cd /usr/local/sbin
wget http://grox.net/software/mine/gethostinfo
less gethostinfo   # you are going to check the code, right?
chmod 755 gethostinfo
gethostinfo | tee /tmp/gethostinfo.out
less /tmp/gethostinfo.out

tcl/Tk Programs

These programs run as-is under un*x (tested on Slackware linux and FreeBSD) and, where noted, under the wish shell on M$ windows. The Windows .exe's have simply been dropped on the excellent tool, freeWrap, to convert them. One of these days, I'll get around to testing them on my Mac...
