2.1 Preparing

Open a terminal on your Linux server as john.  ("regular user" see 1.1 information)
Change to super user.
prompt[home]#> su
Server asks for password:
Give the root password.

Change to directory /usr.
prompt[home]#> cd /usr

Create directory called steam.
prompt[usr]#> mkdir steam

Put john in the "users" group.
prompt[usr]#> /usr/sbin/usermod -g users john

Give john access to the steam directory.
prompt[usr]#> chown john:users steam
Most Linux distributions have a group with the same name as the username.
Thus in most cases chown john:john steam will also do the trick.
The steam directory is now owned by john.

Exit the superuser mode.
prompt[usr]#> exit

2.2 Steam files

Change to steam directory.
prompt[usr]#> cd steam

Download the linux_hlserver_3032004.tgz file to the steam directory.
prompt[steam]#> wget http://www.someserver.com/linux_hlserver_3032004.tgz
or
prompt[steam]#> cp -ipv /home/john/linux_hlserver_3032004.tgz /usr/steam

Unpack the linux_hlserver_3032004.tgz file.
prompt[steam]#> tar -zxvf linux_hlserver_3032004.tgz

New user ?? (existing users skip this step)
Create a steam account using the steam -create option.
prompt[steam]#> ./steam -command create -username john -email john@doo.com -password PaSsWoRd -question "girlfriends name?" -answer jane
(Use your own -email address and -password and think up yr own -question and -answer)

Update steam using the steam -update option.
prompt[steam]#> ./steam -command update -game dod -dir /usr/steam/hlds_l -username john@doo.com -password PaSsWoRd -remember_password
(Use the username and password as specified in the create command or your existing username and password)
Note*
The steam installer will first update the steam installer and will exit the program.
Give the update command again.!
This update process will take awhile depending on your connection speed.

2.3 MetaMod files

Create directory dod/addons/metamod/dlls
prompt[hlds_l]#> mkdir dod/addons/metamod/dlls

or
prompt[dlls]#> cp -ipv /home/john/metamod-1.17.2-linux.tar.gz /usr/steam/hlds_l/dod/addons/metamod/dlls

Unpack the metamod-1.17.2-linux.tgz file.
