Thanks Doug
Yes, it is a modem-router. So let's say PC1 is eth0 (192.168.0.1) and PC2 is eth0 (192.168.0.2) as reported by:
ifconfig -a in every computer
And someone at PC1 writes:
ping...
My net setup is as follows:
internet-----modem----switch----PC1

-------PC2
I'd like to ping PC2 from PC1...
That would mean firing up the browser, logging into the router, switching to the right tab in the web interface, etc. Too slow, plus this way you can't automatize any further task involving the...
Guys, many thanks again for all the answers. This is very enlightening for me :)
This is kind of what I had in mind, but It was only a blurred idea, so thanks for the tip on ifconfig. I'll...
Thanks for all the help guys
But I had a Linux software router (pppoe) running for years (I used the gateway node also as a workstation), and all i had to do was to grep my IP from ifconfig -a....
I thanked you by those but I am looking for a completely local solution, as I'd prefer to not use an external site for such a simple task when my router has all the needed data
Thank for the answers guys
But I'd like to do everything from the bash console, since it is much easier than using the web interface.
Not at all, but I set my old modem up (in router mode) using...
That's a very useful command, many thanks for your help
But does anyone know if there's a local solution to this? It should be possible (and very basic stuff) to "talk" to the router, which is...
Sorry for the question but i couldn't find anything relevant so far. My PC is connected to a HW router which in turn is connected to a modem
internet-----modem----router----PC1
Is there a...
Thanks Imarmisa. Yes they are Linux PCs, so you say I should be able to add non-NAT filter rules to PC1 and PC2 for opening/closing certain ports, for example?
Because it seems that I can't use...
My net setup is as follows:
adsl modem --- adsl router --- PC1

-- PC2
The router's built-in...
Ok drs, I'll investigate further into dmesg.
Again, thank you very much for your kind help
Many thanks drs! I followed your instructions and got it working.
Thanks for the grub2 links, too. I'll start to tweak settings; didn't know it was so different from its predecessor.
There's...
In 8.10 I could change the grub setup so it showed up all bootup info text instead of the boot progress bar and ubuntu logo.
With 9.10 I tried to do it as well (grub 2), but there's almost no info...
A gateway setup is not needed for this most basic ethernet connection. But I made the interfaces' new configuration persistent in /etc/network/interfaces and now I can reboot each machine...
Thanks for the help. However, the opposite *seems* to be the case. I reboot PC#1 and then of course I must do:
sudo ifconfig eth0 192.168.0.1 netmask 255.255.255.0
sudo ifconfig eth0 up
...
Well, I (kind of) found what was going wrong. I was taking for granted that only the ethernet interface of the rebooted PC needed to be reset and re-upped, but apparently even if only one of the two...
I reinstalled kubuntu 8.04 in PC#1 and made no change to its configuration.
Plugged the ethernet cable to the Realtek 8139/8139C/8139C+ card, the green light turned on. The machine at the other...
Here it is:
iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
Chain FORWARD (policy ACCEPT)
target prot opt source destination
sudo iptables -L
Chain INPUT (policy DROP)
target prot opt source destination
DROP icmp -- anywhere anywhere icmp echo-reply

Ok, thanks. But for now I only want to confirm that each PC can communicate with the other one. As I said, in Knoppix I can verify this with ping; something in Ubuntu seems to be conflicting with the...
Sorry for the dumb question, but how can I determine that?
Here's the ouput of "route" in PC#1:
route

Yes, after boot up I write:
In PC#1:
sudo ifconfig eth1 192.168.0.1
In PC#2:
sudo ifconfig eth1 192.168.0.2
