Or another way when you configure the cloud you will note it says requires root access. If you run Terminal (shell) then enter sudo gns3 this will run GNS3 with root access and all will be well

If GNS3 is not installed in a path that linux searches for binaries you will have to enter the full path i.e. sudo /home/ubuntu/gns3

Hope that helps

You guys are rocking and thanks for all the support. Let me jump into my problem.

I’ve GNS3 running inside my Vmware virtual machine and everything seems to be perfect. The problem is that, I can’t ping my router from the VM that hosts GNS3. Also, not pinging from the GNS3 router to the host VM. What could be the problem? I can ping fine with VPCS. I’m sure that my NIO ETH configuration is correct. Can someone help?

Thanks!

ip addressing information required for more troubleshooting. it all works for me.

if you use more than one pc for virtualization test pc to pc then vm to near pc, then vm to far pc. where it fails will tell you who doesn’t know how to get back. that is usually the problem with vm. everybody knows how to get out. the network doesn’t know how to get back.

what I want my gns3 router to have connectivity with all the other devices in my LAN, to continue setting up my virtual voice lab. However, when I follow the steps in this tutorial I’m just able to ping my gns3 router to/from my ubuntu host, but not with the vmware workstation cucm server, the network adapter of that vm is bridge. I have tried the ipv4forward but still doesn’t work. I’m using just one subnet. I don’t understand what you have told me, can you please be more specific.

thanks,

Mike

I’m using fedora 12, and there is no /etc/network directory. I was wondering if anyone knows how to enter the following information into Fedora so that my bridge connection becomes permanent?

auto br0
iface br0 inet static
address 10.10.10.99
netmask 255.255.255.0
gateway 10.10.10.254
bridge-ports eth0 tap0
pre-up ifconfig eth0 0.0.0.0 promisc up
pre-up ifconfig tap0 0.0.0.0 promisc up

Thanks!

first things first, start on the inside and work your way out. you can telnet from your host to your router correct?

in the host ipv4forward
vm network needs to be bridged to server

your host needs a default route
your server needs a static route

or you could use the routed daemon on the server
and peer with the virtual router

your server needs ipv4forward

now give it a try
server should be able to telnet to host

you could even add a static route on your residential router and set up a box that acts like a pod. that’s what i did

questions?

I followed this tutorial several times but I end up getting the same result. I’m running Ubuntu 9.10 64-bit as Host OS and a VMware vm that runs the CUCM, using my wlan0. When I’m done with all the configuration in this tutorial:

- from my host OS I’m able to ping every device (including the router in my GNS3 lab)
- from my vmware vm I’m able to ping my host OS (br0 ip address) and every other device except the router in my GNS3 lab.
- from my GNS3 lab’s router I’m able to ping only the br0 ip address.

I have tried also with ip_forward and using eth0 but still no luck with that either. I need help.

Thanks in advance for your help,

Mike.
