Help, Please!

Hello fellow members of AntiOnline.com I'm having a

promblem with my Red Hat 9 Linux box. Promblem is,

I am unable to surf the Internet. I'm able to ping

the loopback address (127.0.0.1) and get a good

reply but I cannot ping by IP address (like

216.93.104.x) and also cannot ping by hostname

(like www.google.com) for example. When I try to

ping any host name I recieve this message,

immediately

Quote:

---

unknown host

---

Now, when I ping by IP address (other than the

loopback address) I recieve this message, immediately

Quote:

---

Network is unreachable

---

I'm also on a LAN at my home. I have "ADSL" for

Internet service and I have a 4 Port D-LINK

Ethernet Broadband router model DI-604 which uses

DHCP to assign IP addresses to PCs on my LAN.


Now, I'm not able to recieve an IP address from the router. (192.168.0.*) When I

do ifconfig it says IP address 127.0.0.1 no IP

address is being assigned to the system from the router! I recieve a message from the system to "check cable"? So I did, and I even bought a brand new 15 ft Belkin 350mhz CAT5 cable for it today @ Walmart. But I still recieve same messages. Next I checked the PORTS on the DLINK router. I isolated the other PC (red hat box) from the LAN and I used my other PC (windows XP PRO) to check ALL ports on my router and they all got me online so I know my router ports are good. Next I un-installed and re-installed my Linksys NIC card from my PC and activited the NIC card through redhat-config-network it says active but I still am unable to surf the web or ping by IP address. When I try to go to any website it says

www.google.com cannot be found. Please check the name and try again.

For every website. I logged into my router 192.168.0.1 checked the logs for the router, everythings good. I also ran the "cable test" which comes with DLINK checks out; Heres the pic it's PORT 4


Anyone have any ideas suggestions or fixes all help is greatly appreciated.

I'll assume IF config is a typo :)
what do you get for IPconfig/all ?

have you done the standard :

ipconfig/release

ipconfig/renew ???

have you tried to swap the NIC with the one in the XP box ?

I am assuming that your system was existing [ie, it DID work] ?

It's no typo. At the prompt I typed ipconfig it comes back with

ipconfig command not found.

When I do ifconfig

it comes back with all information. This is a Red Hat 9 box I'm having the promblem with not Windows. If it was a windows box this wouldn't be an issue.
But it's a redhat box and on a side note I'm rather new to the "linux enviroment". Thank you for the information.

On a side note heres information on ifconfig

Ooops ......... my bad
sorry for that, I'll bow out now, and try and manitain SOME dignity :)

luck to you

[edit]
Just tonight I spun up Fedora core 3 for the first time, and my Ubuntu discs are about to start their load up ....................... HOPEFULLY I'll be a little better equipped for the next non windoze problem :)

ipconfig is the windows util, ifconfig is the *nix util. In any case, if you assign an IP to the machine staticaly and then ping the router, do you get replies? I would start with this. You should be able to do these things in order:

1) Ping own IP
2) Ping gateway - This verifies local network activity.
3) Ping outside address of the router - This verifies that your gateway is setup correctly
4) Ping another host on the net via IP - This verifies you're getting out to the net
5) Ping another host on the net via host name - This verifies your DNS is configured correctly

My guess is if you can't get a DHCP address then you won't be able to do step 2 with a static IP. If you can then you're doing something wrong with the clients DHCP.

check the file /etc/sysconfig/network-scripts/ifcfg-eth0
It should have a line saying BOOTPROTO=dhcp
Otherwise, if you want to assign a static address,
you could put BOOTPROTO=static
and add a line IPADDR=<whatever address you choose>

Or you could post the contents of the file here and we
could try to figure it out.
