QUESTION: Problem Changing Network Configuration (TCP/IP)

by Brice Rolsto » Mon, 23 Oct 2000 04:00:00

I recently registered a domain name and need to update my host name and dns
servers. When I type 'setup' it brings me to the redhat text setup utility.
I select Network configuration. This brings me to a screen where I can enter
my IP addres, netmask, default gateway and primeary nameserver. I enter
those things and then click 'OK', which SHOULD bring me to the next part
where I can enter hostname, domain name and secondary/tertiary dns... but
instead of going to that, it sort of flickers/flashes and goes back to the
redhat text setup utility, and saves no changes to the network setup.

Thanks for any help.

1. NEWBIE QUESTION: Help on TCP/IP network configuration

Hi!

I have a rather simple question (I think :-). I'm running the
following network configuration.

WinXP RedHat Linux Win95

192.168.10.2<--->192.168.10.1 192.168.20.1<--->192.168.20.2
10.0.0.0

ppp0

The Linux computer has three ethernet-cards, configured like above.
Both WinXP and Win95 can access the internet via ppp0
(ADSL-connection), but the can't ping eachother:
- 192.168.10.2(WinXP) can ping 192.168.10.1(Linux) and
192.168.20.1(Linux), but not 192.168.20.2(Win95)
- 192.168.20.2(Win95) can ping 192.168.20.1(Linux) and
192.168.10.1(Linux), but not 192.168.20.1(WinXP)

My routing table looks like this:
Kernel IP routing table
Destination Gateway Genmask Flags Metric Ref
Use Iface

195.190.xxx.yyy * 255.255.255.255 UH 0 0
0 ppp0

192.168.20.0 * 255.255.255.0 U 0 0
0 eth2

10.0.0.0 * 255.255.255.0 U 0 0
0 eth1

192.168.10.0 * 255.255.255.0 U 0 0
0 eth0

127.0.0.0 * 255.0.0.0 U 0 0
0 lo

default 195.190.xxx.yyy 0.0.0.0 UG 0 0
0 ppp0

With xxx and yyy replaced by numbers :-)

Can anybody help me? Thanks in advance!
