Hi,

I think there is still some vbox-dynamips interconnection bug.

I have a complicated topology, just to give a big picture, three of my Juniper SRX`s are bridged to host eth interfaces so I can use them within GNS3. All of them are connected to dynamips cisco acting as a core network. IPSEC VPN`s, MPLS, BGP,OSPF etc. all that is fine. I am using vbox as end station (http server, icmp, ftp,dynamic vpn,). Now, in such configuration sometimes, or actually quite often all traffic is dropped somewhere, basic interconnection between SRX1 - Cisco - SRX2, vbox-cisco, SRX-vbox stops and I am not really sure what cause that. Issue occur only when more that two vbox are running. What makes this even more odd, sometimes all lab is running for 2-3h with no issue, sometimes crushed right after a few minutes.

In a big projects it is very frustrating, I never know if there is a problem with interconnection or something is messed up with my configs. Always running some ping in the network and when this fail, GNS3,vbox and dynamips needs to be restarted.

Does anyone face the same problem ?

P.S

I am using ubuntu 10.04 as the host but it is exactly the same on other releases.
All vbox are soft cloned, reinitialized MAC, different guest OS versions

Very strange, freaks me up and I have no idea how to troubleshoot that.

The download links to minus.com are not working for me. Is the 8.3 hosted anywhere else?

Hi,

* stopped router + dead dynamips + save = error

Demo:
1 - Start GNS3
2 - Save a project
3 - Add 2 Routers (Minimum)
4 - Start R2 (R1 must be stopped)
5 - Kill Dynamips :)
6 - Save the project (CTRL+S)
7 - Error while extracting R1 config with normal method :D

The idea is to have a mix of stopped/running devices on the map + a crashed dynamips ...

Code:
01:10:33: DEBUG (1): sending to dynamips at 127.0.0.1:7200 -> vm extract_config R2
01:10:33: Dynamips process 127.0.0.1:7200 has crashed

* Port Tracker problem!
1 - Add some devices, last of them with console port 2047
2 - Start a daemon on port 2048 (NCAT.exe --nodns --telnet --exec "cmd" --listen 127.0.0.1 2048 --keep-open)
3 - Add a new device (Dynamips here) with console 2048 (same as the test daemon, ports are in order)
4 - Start the device with console port 2048
5 - Start putty on that Router and guess what: Says Microsoft! :)
6 - Stop NCAT daemon (Dynamips remains ON), and try again with putty. Now is ok -> "Connected to Dynamips VM "R27" (ID 48, type c2600) - Console port"

PS: No crashes in the process. All good! (Only on windows) ;)

Code:
netstat -nabt | grep -E "2048|\["
[dynamips.exe]  TCP    0.0.0.0:2048          0.0.0.0:0          LISTENING
[ncat.exe]      TCP    127.0.0.1:2048        0.0.0.0:0          LISTENING
[ncat.exe]      TCP    127.0.0.1:2048        127.0.0.1:16018    ESTABLISHED
[putty.exe]     TCP    127.0.0.1:16018       127.0.0.1:2048     ESTABLISHED

I have delayed the release a bit to include console and headless support for VBox as well as fixing some bugs. I'll post another pre release soon for everyone to test and then if everything is ok after a few days we can do the official release.

Cheers,

Hi,

Again port tracker (is ok for 127.0.0.1, but not for all)

NCAT.exe --nodns --telnet --exec "cmd" --listen 0.0.0.0 2024 --keep-open

22:56:26: DEBUG (1): returned -> ["100-VM 'R6' created"]
22:56:26: DEBUG (1): PORT TRACKER: allocate port 2024

Hi,

I've updated the packages + CHANGELOG (see first post).

Quote:

I use the host (127.0.0.1 or any other selected binding) int bind(). I could use 0.0.0.0 for the bind test but what if the user has more than one network adapter? For instance can we consider a port has taken if it is only listening on one adapter and not on a second?

Cheers,

Hi!

Regarding vboxwrapper on osx.

Something with the file permissions still, but after 'chmod a+x vboxwrapper.py' I get:

'Could not connect to vboxwrapper at localhost:11525'

Code:
sh-3.2# python vboxwrapper.py
Traceback (most recent call last):
  File "vboxwrapper.py", line 43, in <module>
    from tcp_pipe_proxy import PipeProxy
ImportError: No module named tcp_pipe_proxy

Hi,

My bad I forgot to include one file. I updated the package for OSX.

I'll fix these permission issues later.

Cheers,
