Most modern Linux distributions have user-friendly programs to set the timezone, often accesible through the program menus or right-clicking the clock in a desktop environment such as KDE or GNOME. Failing that it's possible to manually change the system timezone in Linux in a few short steps.

1.  Logged in as root, check which timezone your machine is currently using by executing `date`. You'll see something like "Mon 17 Jan 2005 12:15:08 PM PST -0.461203 seconds", PST in this case is the current timezone.
2. Change to the directory to /usr/share/zoneinfo, here you will find a list of time zone regions. Choose the most appropriate region, if you live in Canada or the US this directory is the "Americas" directory.
3. If you wish, backup the previous timezone configuration by copying it to a different location. Such as `mv /etc/localtime /etc/localtime-old`.
4. Create a symbolic link fr om the appropiate timezone to /etc/localtime. Example: `ln -s /usr/share/zoneinfo/Europe/Amsterdam /etc/localtime`.
5. If you have the utility rdate, update the current system time by executing `/usr/bin/rdate -s time.nist.gov`.
6. Set the ZONE entry in the file /etc/sysconfig/clock file (e.g. "Europe/Amsterdam")
7. Set the hardware clock by executing: ` /sbin/hwclock –systohc`

Tips

• On some versions of RedHat Linux, Slackware, Gentoo, SuSE, Debian, Ubuntu, and anything else that is "normal", the command to display and change the time is 'date', not 'clock'
• On RedHat Linux there is a utility called "Setup" that allows one to select the timezone from a list, but you must have installed the 'redhat-config-date' package.

Warnings

• Some applications (such as PHP) have separate timezone settings from the system timezone.
• On some systems, there is a system utility provided that will prompt for the correct timezone and make the proper changes to the system configuration. For example, Debian provides the "tzsetup" utility.

Shit that happens

• Once I had a "wrong" timezone file. Using the /usr/share/zoneinfo/Europe/Amsterdam file the server refused to move to another timezone and wanted to stay in the Chicago timezone. After copying a Amsterdam timezone file from a working server the problem stopped.

# mkdir cd /tmp/restore_etc
# cd /tmp/restore_etc
# mt -f /dev/rmt/0mn rew (terugspoelen)
# mt -f /dev/rmt/0mn fsf 1 (fast forward)
# tar xvf /dev/rmt/0m etc (restore directory)
NO slash preceding "etc"

# cp -R -p -i . /etc/
Don't overwrite exisiting by pushing the N key

Another way:
# tar xvf /dev/rmt/0m etc/aliases (restore single file)
NO slash preceding "etc"

edit sudo userfile:
#visudo
toevoegde regels:
user1  ALL=/usr/sbin/sam, /usr/bin/vi /etc/hosts
user2  ALL=/usr/sbin/sam, /usr/bin/vi /etc/hosts
user3    ALL=/usr/sbin/sam, /usr/bin/vi /etc/hosts 

Edit .profile files of user user1, user2, user3:
alias sam="/opt/iexpress/sudo/bin/sudo /usr/sbin/sam"

This helps the user on the commandline to start SAM.
Root rights for a normal user using sudo on /etc/hosts if you execute the command "sudo vi /etc/hosts".

Aanpassing gedaan om in mail domein en servernaam te krijgen:
@ELITIL1.elisabeth.nl ipv @elisabeth.nl.

Zie hier hoe:

<b>/etc/mail/sendmail.cf</b>
# my official domain name
#Dj$w.Foo.COM
#Dj$w.elisabeth.nl

# masquarade as, aka site hiding(null for no masquerading)
#DMelisabeth.nl
DM

Restricted SAM geintroduceerd voor account itakroot en beheer.

Voor beide accounts alleen rechten in sam voor beheer van printers en users.

<b># cat /home/itakroot/.profile</b>
#alias sam="/opt/iexpress/sudo/bin/sudo /usr/sbin/sam"
alias sam="/usr/sbin/sam"

Eerste alias regel is niet meer nodig aangezien er niet meer met sudo wordt gewerkt.

<b># visudo</b>
# toegang tot SAM voor de volgende users
#itakroot  ALL=/usr/sbin/sam, /usr/bin/vi /etc/hosts
#techdata  ALL=/usr/sbin/sam, /usr/bin/vi /etc/hosts
#beheer    ALL=/usr/sbin/sam, /usr/bin/vi /etc/hosts

itakroot  ALL=/usr/bin/vi /etc/hosts
beheer   ALL=/usr/bin/vi /etc/hosts

Alle sudo regels uitgeschakeld voor starten van sam.
De file /etc/hosts is voor itakroot en beheer aan te passen door gebruk te maken van het commando <b>sudo vi /etc/hosts</b>. Het aanpassen van deze file vereist root rechten.

# useradd -g 101 -d /home/ajmhelvo -s /sbin/sh -c "Angela van Helvoirt"  ajmhelvo
# vi /etc/passwd

aanpassen:
ajmhelvo:*:309:101:Angela van Helvoirt:/home/ajmhelvo:/sbin/sh
naar
ajmhelvo:*:309:101:Angela van Helvoirt:/usr/cible1/files:/sbin/sh

# passwd ajmhelvo

To create a "new" position choose one of the names from the list of positions shown in
site>template manager>module positions

In your template add:

  <?php mosLoadModules ( 'position_name'); ?>

You will want to  surround it with approprate html so that it appears where you want it to and with the formatting you want.
