Title: Cannot get dynamically assigned IP address
Post by: mz on January 03, 2003, 09:57:49 PM

FYI- new user, new setup

Cannot get an IP address from cable provider. Have reset the modem and rebooted the server.
Configured as Server and gateway (was initally setup as Private only)
Running the test connection to internet fails.
Internal card / network works fine.
Network cards - Kingston internal fine; external facing is Compaq - both 10/100

Suggestions?

Have you used that NIC with the cable modem before? Some providers track the MAC address, and a new NIC won't work until you call customer service and they update their database with the new MAC...

I too had this problem once. After a bit of trial and error, I powered off my cable modem and rebooted the sme server. Only then did the server pick up its external address from the ISP. Maybe this will work for you too.

Since you didn't report any testing results you might try using ifconfig to 1) list your ethernet setup and 2) try to bring up your external NIC.  Please pardon me if you already know the syntax!

Simply put, run ifconfig from a shell prompt to see what your NICs are doing, and pipe it through "more" to see a page at a time:

ifconfig | more

(On my keyboard the pipe is shift-backslash.)

To try to bring up your external interface:

ifconfig eth1 up

You can access a shell prompt by hitting ALT-F2 on the server's keyboard after it boots & shows you the admin screen, or by using an SSH-capable program such as PuTTY.
