Network connection problem

harken · 01-19-2005, 06:04 AM

syl20, that's exactly what I'm asking. I said that at the beginning (after install) Debian's DHCP client worked fine and was able to assign me a dinamic IP. Therefore, I presumed that my network has a DHCP server configured. I asked why am I not able anymore to get an dinamic IP. Should I contact my network admin or is it a local machine configuration problem?

What do you want exactly? A dynamic or a static IP?
I don't know debian, but under redhat, you have to configure a file called ifcfg-ethX (X=0, 1...) (maybe /etc/sysconfig/network-scripts/ifcfg-eth0 if no, 'updatedb' and 'locate ifcfg'. ) That's /etc/rc.d/rc.inet1.conf for slackware.
You should have a look at this file and googling to know parameters.
Yes you should contact your network administrator, he will either give you a static IP or tell you the @ of the DHCP server.

I appreciate your help syl20, but if you would have read carefully what I wrote so far, you wouldn't be asking me what exactly do I want.
I repeat: right now my computer has assigned an static IP (the same one I have under Win XP) and the network connection runs almost ok (there still are some problems on the ISP's side).
I am just wondering why the DHCP service isn't running anymore.
That's what I was trying to say in my previous posts.

umm
Static IP = No need for DHCP
Dynamic IP = Need DHCP server to obtain an IP

DHCP Service?? on youe PC or the network?

if your admin assigned you a staic IP then either
A. there is no DHCP server in your network or
B. there is a DHCP server and your not apart of that network or sub-net if you prefer

Damn, do I really look that dumb?
Of course you don't need DHCP (DYNAMIC Host Configuration Protocol) if you have an static IP assigned.

One task of DHCP is to assist in the problem of getting a functional and unique IP number into the hands of the computers that make use of the Internet.

DHCP's purpose is to enable individual computers on an IP network to extract their configurations from a server (the 'DHCP server')

Then maybe you'll explain me how comes that 3 days ago I was connecting to the Internet using an dynamic assigned IP by DHCP and suddendly I can't anymore.

How can we know if the DHCP server on your network may have be down??????
If you didn't make any changes on your PC, the pbl can't come from your PC.
Ask your network administrator for more details! He will help you!
