Ping from Debian to WinME (vice versa) failed :(

Elijah · 08-23-2003, 11:16 PM

Ok, I've little networking knowledge and this whole thing is confusing me. My Ethernet card is a Davicom compiled in the kernel, Ifconfig outputs lo only so I have to do "ifconfig eth0 192.168.0.1 netmask 255.255.255.0" to bring eth0 up.

The IP of WinME is 192.168.0.2, subnet of 255.255.255.0 and a gateway of 192.168.0.1. (My debian box has the internet connection).

My problem is whenever I try to ping my WinME, it fails and so does WinME to my linux box.

Is your Firewall (iptables) allowing pings through?

Thanks for the quick reply, er, I'm using firestarter for my firewall ... whenever my dialup connection connects, I start firestarter.

On the firestarter rules I set my trusted hosts to 192.168.0.2 ( my WinME) ... but even if it's turned off, I still can't ping

So you've set your Linux box up as a router to the windows box, To share your modem connection.

Hmmm is multicast setup and everything?

Edit:

Ignore me about the Multicast I was thinking of something else. Sorry.

HAve you set the Linux machine to route packets to the WinME machine?

ip multicasting seems to be compiled on my kernel ( I just checked) but I don't think it's configured yet ... do I need it? from google it looks like it's for audio/video/phone-tools conferencing or something ... all I needed right now is for my pinging to work, I'll try to figure out internet sharing right after that's done.

edit: route packets? I don't think I did, how is that done?

You won't be able to ping without first setting up your network properly.

Routing packets is what you do when you share the internet. When the WInME machine request a page from the web, it sends it request to the Linux Machine, this machine then forwards the request on, when it comes back the Linux machine will know its for the WinME machine because of IP address etc, and will route the packets back to the WInME machine.

Try Looking through some how-to's on Networks an Internet Sharing, start here:

or

http://www.tldp.org/HOWTO/Linux-Mode...ing/index.html

This should get you going.

Thanks for the links, I've already done some of the steps mentioned there... it seems that I've missed out on the 'routing' part. But this time I'm getting some messages from the ping, rather than the last ping I made which made no real-time messages, it simply points out it sent this no. of packets w/ 100% packet loss..

Code:

Valhalla:/home/elijah# route
Kernel IP routing table
Destination     Gateway         Genmask         Flags Metric Ref    Use Iface

--- 192.168.0.2 ping statistics ---
4 packets transmitted, 0 packets received, 100% packet loss

it looks like whenever i bring eth0 up it automatically creates a route ..

now I have 2 of the same route rule.... I deleted one and it still won't ping.

doing a

Code:

route add default gw 192.168.0.1

seems to loose my connection, my browsers won't resolve until I deleted the route.

still no luck

edit: I'd like to add that when I dual boot to xp > winME, it network works fine...
also my firestarter firewall is turned off right now...
