Hello All,
A good source to go to for Linux and Security is www.LinuxSecurity.com.
They have a lot of good beginner articles as well as advanced articles.

Take a look at our site as well... we have a few howto's on security (iptables
tutorials, logging etc etc). Might come in helpful.

Ah!, i can duduce what you mean, you meant, take a look at
www.linuxvoodoo.com
I wonder how many are thinking right now, what site does he mean.
It may be a good idea to announce the "full" URL so folks can simply click on
it and "see" what you mean without them having to think.

First learn linux well. It takes 2 years to really learn linux.
(how it bootsup, inet, sendmail, dns, http server few of them)
To understand and implement any security on linux or
any other system you need to understand the system.
Along with learning these issues you can read securing
and optimizing redhat linux which is little outdate free copy
and you have to pay $$ for latest. Eventhough it is redhat
specific it has got good concepts you can grab.
all the best,
Sam

If I read the online docs for msec correctly, the standard mask for
permissions is normally determined by the security level you choose to run
msec at; the higher the level, the more restrictive the permissions. But
this is one of the things you can modify independent of security level, by
settings in
/etc/security/msec/perm.$PERM_LEVEL
or
/etc/security/msec/perm.local
Look in http://www.mandrakeuser.org/docs/secure/smsec.html for the details.

Sean,
That was a typo. I've made some progress with Rays help. It appears
msec is causing the problem. It keeps running and revoking the write on
the /home/everyone subdirectory for the group. I'll work on msec.
Thanks for the help

Could just be a typo, but r adds read privileges. g+w would add write
privileges.

If that wasn't a typo, then it would explain why you can't write a new
directory in the /home/everyone folder.

This step looks wrong:
chmod g+r /home/everyone
Don't you want this to read
chmod g+w /home/everyone
or
chmod g+rw /home/everyone
since making a "folder" (a subdirectory in Linuxspeak) requires writing to
the directory, not reading it?
Anyway, see what "ls -l /home |grep everyone" reports about permissions for
/home/everyone . Even if I've got the chmod options wrong, you want to have
the directory writable by its group ... so make sure the permissions are
something like drwxrwxr-x. "chmod 775 /home/everyone" should produce this.
If that's not the problem, take a look behind the curtain of the commands
you're trying to see what is actually wrong (though the rest of the
commands you report look OK to me). Look at (or show us) this:
the entry in /etc/groups for "everyone"
the output of "ls -l /home | grep everyone"
the actual error response when userid dave executes these commands
touch /home/everyone/sometestfile
mkdir /home/everyone/somedirectoryname
(or some equivalent commands ... but show both the
exact commands and the exact errors)
Also mention if there is anything unusual about what you are doing ... for
example, if an NFS or SMB mount is involved, or if you log in as someone
else then su to dave, or ... you get the idea.

I've been runing Mandrake for a couple of years and I'm still having
problems with groups.
This is the procedure for making a group and sharing a subdirectory that
I use. Can someone tell me where I'm screwing up? Thanks in advance
Make a folder: mkdir /home/everyone
make group: groupadd everyone
add users gpasswd -a dave everyone
add users gpasswd -a laura everyone
change the group for the folder chgrp -R everyone /home/everyone
add write for group everyone chmod g+r /home/everyone
When I'm done with this I still can not make a folder in /home/everyone
logged on as dave.
again thanks for your help
