Truecrypt User Mount

If you have truecrypt and want to mount a volume using the gui, you will notice that it requires root access to mount.  Here is how to use the gui to mount and unmount volumes as a user:

First we need to create a group which will have all the permissions required for our users to mount and umount volumes

Login to a shell as root and type the following commands:

groupadd truecrypt

now we need open the visudo file and add permissions for the truecrypt group to work:  (I added the line to the bottom of the file)

visudo

# Users in the truecrypt group are allowed to run truecrypt as root

%truecrypt ALL=(root) NOPASSWD:/usr/bin/truecrypt

make sure you save and exit (if you do not know how to use visudo or vi, man visudo or man vi will help you, you can also google for common vi commands.  IT IS NOT RECOMENDED TO EDIT THE VISUDO FILE FROM ANOTHER EDITOR.  THE SAFE WAY TO EDIT THE VISUDO FILE IS TO RUN VISUDO FROM A ROOT SHELL

Finally we need to add our trusted users to the truecrypt group so they can mount and unmount truecrypt files.

gpasswd -a USERNAME truecrypt

Boinc Slackbuild on github

Since Slackbuilds will not host my BOINC slackbuild which uses svn to download, compile sources, I created a github account and uploaded them there.

Disable root access on SSHD

Why slackware does not initially disable root access on SSHD is beyond me, here is how to turn it off:

login as root:

nano /etc/ssh/sshd_config

Change from:

# PermitRootLogin yes

Chang to:

PermitRootLogin no

Save and exit

Issue command:

/etc/rc.d/rc.sshd restart
