Welcome to LQ.

How far have you got?
Have you connected all computers and got link lights on the hub and cards?

Are your other computers already networked?

If they all have ip addresses can you ping them from each other.

how do i ping from linux?
how do i find out ip config in linux?

thanks

Ping is the same as windows:
ping your.ip.add.ress

To get your ip (like ipconfig):
ifconfig

excellent, that worked fine.
(it kept on pinging so had to kill the application)

Well if you cna ping the computers then you are networked ok. If you want to access files on windwos from linux look at the smbclient command.

To share files with windows you will need to add users using "smbadduser" or "smbpasswd". Make sure that you have the samba services running:
service smb restart

You can edit the smb options by editing /etc/samba/smb.conf - to find out about the config options then try running "man smb.conf". Make sure you make a copy of the config file if you intend to change it.

Other than that, just make sure you have no firewall rules blocking ports 137, 138 & 139.

ifconfig 192.168.0.1 netmask 255.255.255.0
am i assigning a ip addr to my machine with mask

what does localhost.localdomain mean

You should also specify a device to allocate the address to - eg "eth0".

localhost.localdomain as a safe sample domain for you system. localhost and localhost.localdomain shount NOT be removed from your hosts file but you can set your hostname to what you want. To change it run "hostname myhostname". To make the change permenant - edit /etc/sysconfig/network and add/modify the HOSTNAME entry like:
HOSTNAME="myhostname"
