Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

Has anyone had a problem with the redhat-config-users app? (aka System Tools->Users and Groups)
Just the other day, I was configuring some user stuff, and I created a new user, and gave them a default group ID of 100 (ftp on my sys) the app gave me a warning, "We don't recommend giving a default group ID of less than 500" so I thought "I wonder why" I aborted it (clicked cancel) to do a little research before continuing. The "Add new user screen" greyed out, and did nothing. Half an hour later, it was still doing nothing. so I called up my trusty task manager, and killed (-s 9) the offending app. Ever since, I have been unable to run redhat-config-users.
Help! Please, coz redhat site is rubbish, nowhere has got any info, have I missed something glaringly obvious?
majic, usually on Redhat, the default uid and gid defaualts to 500. <=100 uid and gid are used for administrative accounts, that is why you got that message. You killed the stalled app. which is fine, but now you have to re-start it to use it again.
Hope this helps.
I don't know if it's reproducable (I don't want to have to rebuild my system all over again!) but if anyone wants to have a go, here's my config:
RH9, with modutils 3, Kernel 2.6.8.1, No KDE, just Gnome.
HDA> 1G Boot, 18G /
HDB> 512Mb Swap, 512Mb /tmp
Procedure to follow:
Start redhat-config-users
Add new user
create home directory /home/user
don't create group for user
Add user to group 100
Click OK
Message box ("We don't recommend giving a user a group ID < 500, do you wish to proceed") click cancel
On my machine, it hung, and if I wasn't in the middle of a project, I'd try and reproduce the prob, as it is, I can use the console tools, and live without the graphical interface for a little while
If anyone else wants to have a go, post your results here
