“May be problems with running as a normal user can solve setuid-bit?

chmod +s dynamips”

You MUST change owner to root and only then +s will make a job done… else the dynamips will be launched with your UID (and your permission accordingly) so it doesn’t make a sence…

Chiguidagui,

It sounds like you are having a problem with bridging. Try this tutorial.

Hi Josh,
I forgot to tell you that:
1.- I have try clearing arp on both machines (XP and Ubuntu);
2.- I had rebooted all the PCs and restarted all conections from scratch;
3.- I had sniffed the traffic;
4.- I had controlled the arp table over and over again.
5.- I had debugged the ip and arp traffic from R1
6.- I had manually populated the arp table with the missing values, but it does not help at all…

No matter what I try the arp table has always an “incomplete” value for the other device on the Ubuntu machine…

Meaning (and this happens only on the Ubuntu PC):
1.- On R1, there is an incomplete entry for the Cloud (“nio_gen_eth:eth0″ – 10.0.0.5/29)
2.- On the Cloud, there is and incomplete entry for R1 (on GNS3 – ios 7200, – 10.0.0.2/29)

Do you think that there may be a default firewall (on Ubuntu) protecting any of these devices ???

Thank you,
Tony

Hi Josh,
The problem is on the Ubuntu machine…

I am able to ping from both Ubuntu/GNS3 devices to XP and from XP to both Ubuntu/GNS3 devices.

I am not able to ping none of the devices on Ubuntu from the other Ubuntu device…
Meaning: I am not able to ping the Cloud (Ubuntu/GNS3 “nio_gen_eth:eth0″ at 10.0.0.5/29), from R1 (Ubuntu/GNS3 – ios 7200, at 10.0.0.2/29) neither the other way around.

The problem is on the Ubuntu/GNS3 devices.

Ubuntu eth0 does not see GNS3 R1 and vice versa…

Thanks
