This website is currently under construction, but we hope to add a number of useful tutorials, howtos and links.

We also aim to include various additional sections for users of other 'nix's such as Irix and Solaris.

To change IP Address of server

This can vary depending upon which 'flavour' of Linux you're using. Generally you should edit the following files:-

/etc/resolve.conf - defines name servers
/etc/sysconfig/network - defines IP address and netmask etc
/etc/sysconfig/network-scripts/ifcfg-eth0 - defines settings for network card

If you've built an Ubuntu server, you'll probably find that by default it's been configured to pick up an IP address via DHCP. If this is the case, you need to edit the /etc/network/interfaces file and you'll find a line which looks like

iface eth0 inet dhcp

You need to change this to read as follows:-

iface eth inet static
        address 10.1.1.100 (or whatever IP address you require)
        netmask 255.255.255.0
        network 10.1.1.0
        broadcast 10.1.1.255
        gateway 10.1.1.1 (or whatever the IP address of your router is)

Don't forget to change the name servers in the /etc/resolv.conf file and now you'll probably want to uninstall the DHCP client to prevent it trying to run DHCP in future.

apt-get remove dhcp3-client

N.B. Above commands should be done as root.

You should now restart the network interface:-

/etc/init.d/networking restart
To change the date

The date and time can be set with the date command. The syntax is: date MMDDhhmm[[CC]YY][.ss]

The alternative solution is to install NTP and let the server synchronise the time/date from the internet.

Setting the Time Zone

Type the following:- export TZ=BST (or GMT etc.)

To synchronise the hardware clock, type:- hwclock --systohc --utc
