I've finally got my network card to work in RH 7.2 (Intel EtherExpress) and it seems to be working fine (ie. initialised at boot time, listed in ifconfig, modules.conf, ioports, interrupts).

On this RH7.2 box, I can ping myself(eth0=192.168.0.2) no probs.

On my win2k box (the only other machine in my home network), I can also ping myself (192.168.0.1) but they can't seem to ping each other (host unreachable).

The lights on my hub show that the connections from these machines are up so I suspect it's a rounting problem but not sure how to correct it using Network Configuration in GNOME.

Any help will be welcome (or tell me what other infor to post if that helps)


Thanks

A few things to check:

-Type "route" (no quotes) in a term window and post the output.

-Is the hub a plain hub, or is it a broadband Internet gateway/router? If it's the latter, you need to enter its IP as the default gateway.

-If connected to the Internet, can you surf form either box?

-If you're doing any firewalling, make sure it isn't blocking the ping requests.

-Do both machines have an entry in /etc/hosts?

Ok
1)Here is the output from route:

Kernel IP routing table
Destination--Gatewy--Genmask---------Flgs--Met--Ref--Use--Iface
192.168.0.0--bob------255.255.255.0--UG------0----0---0----eth0
192.168.0.0--*---------255.255.255.0--U--------0----0---0----eth0
127.0.0.0-----*---------255.0.0.0---------U--------0---0----0----lo
default--------bob------0.0.0.0------------UG------0----0---0----eth0

(added dashes to keep the formatting)

Note: Bob is my win2k box, Molly is my Linux72 box.

2)Hub is stock standard hub (not router/switch etc)

3)I have a modem attached to my win2k box and can surf the net but my linux box can't.

4) No firewalling switched on at all

5)Linux hosts:

# Do not remove the following line, or various programs
# that require network functionality will fail.
192.168.0.2 molly molly
192.168.0.1 bob bob
127.0.0.1 localhost.localdomain localhost

How do you check this on win2k machine?


Thanks

try

route add 192.168.0.1 gw 192.168.0.2

192.168.0.1 being the destination network (your windows box) and 192.168.0.2 being the NIC it's on on your linuxbox.

Didn't work. I now think it's my win 2k box.(Local Area Network says no pakets sent/received and the hub light for this connect doesn't flash when issue a ping command.

Thanks anyway.

No. 192.168.0.1 is not the destination network, it is the address of another node on the 192.168.0.0. network (in this case, the Windows box).

Well yes, that is the Linux box's NIC's address on the LAN, but it is not the gateway address to the outside world; the gw addr would be the address of the Win box's NIC (192.169.0.1). As spato said though, it sounds like more work had to be done on the Win box's side to pass requests from the LAN (via the NIC in the Win box) to the modem, and then on to the outside world.


Spato:

I don't know if you can reference host names (as opposed to IPs) in your routing table, but my guess is not. Even if it is do-able, I'd stick with pure IP references in the routing table.
Here's the output of route from one of the Linux boxes on my LAN:

-The 192.168.0.0 network entry can be generated by:
route add -net 192.168.0.0
(although this is doesn't usually need to be explicitly specified, as it seems to be derived from your other entries)

-The "default 192.168.0.1" entry is the address of my router, which you can specify by:
route add default gw <LAN-side IP of router>. Since your Linux box seems to be getting it's Net access though the Win box and it s modem, I would think that the gw entry in the Linux box's routing table should point to the IP of the NIC in the Win box.

I think your win2k box is locking down those ports, but I don't know how to check that for win2k. basically, MS has decided that you shouldn't be pingable.... I know that XP gives my friends weird troubles in that regard. perhaps win2k is similar.

try running an http server on your linux box, and see if your win2k box can bring it up. or, start a telnet server, and try to telnet into your linux box.

ahh, it seems i have things backwards. anyways, this is how i have things on my server, with ip masquerading on ppp0.


ok... hmm. I have a net set up with 3 win boxes using 10.0.0.5, 10.0.0.6, and 10.0.0.7, and three nics in my linuxbox using 10.0.0.1, 10.0.0.2, and 10.0.0.3 and until i execute

route add 10.0.0.1 gw 10.0.0.5
route add 10.0.0.2 gw 10.0.0.6
route add 10.0.0.3 gw 10.0.0.7

none of the computers can ping any other computer, including the server, or anything on the internet untill i do this.

U forgot that I can't ping from win box to linux box either.Also, I didn't have this prob on another LAN (with win2k box (same ver) and RH72 box) so I'm fairly sure its my Win2k NIC.

DMR
Thanks.I'll replace NIC in win2k box first tho and then c what happens.
