I would like to help, but you need to provide some information.

Please open a konsole, and run the command '/sbin/ifconfig' ( without the quotes ) and paste the results to this thread.

It would also help if you tell us what you are trying to set up, static IP or DHCP, the card, chipset etc. Is this wireless, or a wired card?

It would also help to know what distro you are running = ) Some of the distros have little gui's that might help out.

PCLinuxOS Configuration Utility (PC - System - Configuration - Configure Your Computer), entered the root password, select Network and Internet and then Configure a new connection and finally select DSL.

optionally you could edit /etc/pppoe.conf and do pppoe-start but the gui is probably easier

It appears your system has a ethernet driver insalled, since you got some output from '/sbin/ifconfig'. You also do not have an IP address.

Most distros will come configured for DHCP. It would appear your system is not seeing the DHCP server. Do you know what box is supplying that function? ( commonly done in your router ).

Could you look at the lights on the network where you plug your ethernet cable in to see if there are green light(s) or not and let us know? A green light shows hardware conectivity. Nice to know if your cable is good or not.

Also, when you cut and paste on the forum, try to use the Quote button at the top of the editing window, paste between the quote and equote markers. It makes the text much more readable. Example, my ifconfig output:

Quote:
/sbin/ifconfig eth0
eth0 Link encap:Ethernet HWaddr 00:1D:7D:20:F4:67
inet addr:192.168.1.26 Bcast:192.168.1.255 Mask:255.255.255.0
UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1
RX packets:53115 errors:0 dropped:0 overruns:0 frame:0
TX packets:46331 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:1000
RX bytes:70525134 (67.2 MiB) TX bytes:4731146 (4.5 MiB)
Interrupt:19 Base address:0xe000
Note the second line, that is where the IP address shows up...

well what do you mean by " what box " ?
the greens are ok.. and the cable is fine coz i tried it on another computer.

would it help you if you knew that im trying to connect to a local network , a server and a hub..

another thing: when i try to configure firefox and check a site.. it says that " firefox is configured to use a proxy server that is refusing connections "

well Im not good at networks an connectivity but i can still notice that there's a thing behind this...

thanks

i'm very confused - why are you trying to use DSL to connect to a LAN? if that's what you mean...?

you can change firefox to not use a proxy server within firefox settings.

I'm asking if you know which machine in the network if the DHCP server?

It can be a router or a host system like linux. When you run DHCP, your machine initially does not have a valid IP address. It sends out a broadcast message requesting an IP address to be assigned from the server. If the server sees the request, it will return a valid IP address to your system, and you will see it when you run the ifconfig command. This is the same for windoze as well as linux ( or any other OS ).

This is good, you have verified the cable is working.

A proxy server is used for security. When a network is designed, corporate networks, school networks etc, proxy servers are often the only way to access the public internet, by design. Some proxy servers you may need to log into with a user ID and password. In other words, the designers are controlling things. This is common on some wireless setups. It prevents unauthorized users from using the resources. You will have to talk to the administrators to find out why you are being "refused". The server may be checking MAC addresses, yes you have one, every NIC has one. This is the hardware address put there by the manufacturer of the card. The admins may have to add your nic ( if that is what they are doing ).

If you do not require access beyond the local network, you can assign a static IP address. Be careful, you should not assign one that is part of a DHCP pool of addresses. You can cause problems for the admins. For example, lets say you are trying to connect to lan 192.168.5.x. The DHCP server may be using the first 128 adresses. You need to pick something out side of that range, say address 192.168.5.240. This is just an example. If you used one inside the range, someone will connect to the server, the server will hand out your address, and an error will log of 'duplicate addresses' Sooner or later the admins will see it is your MAC address and track you down. Don't do that.

The correct way is to find out how to get access to the proxy server, and any other authorization you need to connect to the DHCP servers.
