| Hi All,
I am trying to set up a "simple" network between just two computers:
- Dolphin, which is running Windows XP Home, and
- Penguin, which is running Red Hat Linux 9.
Dolphin has an existing trouble-free dial-up modem (Softk56 Data Fax Voice
Speakerphone CARP) link to the internet via a local ISP, which I'd like
Penguin to be able to access along with some other useful peripherals that
Dolphin has (printer, CD-RW, etc).
Each computer has a Realtek RTL8139/819X NIC and I have connected them via a
3m Category 6 Crossover cable (RJ45). Each claims to have installed the
drivers and that each card is working correctly (presumably just
hardware-wise).
In the XP machine, the Network Setup Wizard failed without any clue as to
why, but I set the IPs manually. Thus I used:
Control Panel->Local Area Connection->Internet Protocol
(TCP/IP)->properties. I took the "Use the following IP address" option as
follows:
IP address 192.168.1.11
Subnet Mask 255.255.255.0
Default gateway 192.168.1.1
Preferred DNS server 203.96.152.4
Alternate DNS server 203.96.152.12
Still in Dolphin, I edited the file C:\WINDOWS\system32\drivers\etc\hosts to
read (comments aside):
127.0.0.1 localhost
192.168.1.11 dolphin dolphin.mshome.net # This computer's name
192.168.1.12 penguin penguin.mshome.net # Linux computer's name
- Now looking at Penguin, the RH9 machine, I edited the file /etc/hosts to
read:
127.0.0.1 localhost.localdomain localhost
192.168.1.12 dolphin.mshome.net dolphin
192.168.1.11 penguin.mshome.net penguin
And running the "neat" tool for eth0, I set:
IP address 192.168.1.12
Subnet Mask 255.255.255.0
Default gateway 192.168.1.1
OK: so sitting in Dolphin, under a command window:
ping 127.0.0.1 works
ping 192.168.1.12 works (i.e. no packet loss), *but*
ping 192.168.1.11 just hangs.
The same thing happens from Penguin, ie,
ping 127.0.0.1 works
ping 192.168.1.12 works, *but*
ping 192.168.1.11 just hangs.
So the XP machine *cannot* seem to ping itself (192.168.1.11) but can,
apparently, ping the Linux machine through the NIC connection! Then again,
the Linux machine (192.168.1.12) *can*, apparently, ping itself but not the
XP machine!
Yes, I've tried disabling firewalls on both machines and yes I have tried a
variety of pairs of IP numbers in the 192.168.x.y range.
Please help - this is driving me crazy. No dancing the Samba until there is
two-way pinging!
Thanks in advance,
Wayne
