UNIX for Dummies Questions & Answers

I have Solaris 9 x86. I would like to use DHCP to connect to the internet. How can I make it work. A lot of tutorials say about editing files - Is there any easier way? (I am a newbie to UNIX).

Please Help

login as root
check what interfaces you would like use (ifconfig -a)..

to enable the interface for dhcp do this as root

cat /dev/null > /etc/hostname.XXX
cat /dev/null > /etc/dhcp.XXX

where XXX is the name of the network interface like hme0, qfe0, eri0, ce0, bge0 or something like that..

after you are done with that simple reboot or issue the following command to make the change right away if you cant reboot

ifconfig XXX dhcp start

The following commands can be used to display the DHCP lease information and release the DHCP lease, respectively:

ifconfig XXX dhcp status
ifconfig XXX dhcp release

I have a trouble with connecting to the internet from the Solaris UNIX.

I posted once a thred "Setting a DHCP client under Solaris" and got the following answear:
--------------------------------------------------------------------------------
cat /dev/null > /etc/hostname.XXX
cat /dev/null > /etc/dhcp.XXX
where XXX is the name of the network interface like hme0, qfe0, eri0, ce0, bge0 or something like that..
after you are done with that simple reboot or issue the following command to make the change right away if you cant reboot
ifconfig XXX dhcp start
---------------------------------------------------------------------------------
I tried that and:

-My Hostname changed to 'Unknown'!
-I can't view any website with wy browser (Netscape)

Here is what the computer says:
(My network interface = rf0)
-----------------------------------------------------------------------------------
Sun Microsystems Inc. SunOS 5.9 Generic January 2003
