running mtr in guest crashes the guest => Fixed in SVN

[Stéphane Charette]

VBox 2.1.2. Host is Ubuntu 8.10-64bit. Guest is Debian Etch 4 64-bit. I've tried both NAT and and host interface.

From a command-line in my guest, I run "mtr 192.168.42.99" where that IP is at the other end of a openvpn tunnel.

About 1 second after mtr starts to run, the guest completely crashes. The VBox GUI says the guest has been "aborted". I'll attach the machine log file.

I've tried the same thing with a Ubuntu 8.10 32-bit guest that is not using openvpn, and did not see the crash. On my Debian guest, it crashes 100% of the time, always about 1 second after starting the network tool mtr.

When I run "mtr 192.168.1.3" -- where that address is a local LAN address -- then everything works fine, the guest does not crash.

But when I run "mtr 192.168.42.99" -- where that address is a host on the other end of the host's openvpn tunnel -- then the guest crashes as described.

Note that ssh and sftp through the tunnel works fine. mtr seems to be the only thing to cause a crash.

OpenVPN is installed in the host when the guest is in NAT mode.

When the guest is installed in host interface mode, I turn off openvpn in the host, and instead installed openvpn within the guest. Again, I can confirm openvpn is instaled correctly since I can ssh and sftp to the various hosts through the tunnel.

Thanks for the e-mail, Frank. That completely fixes this problem. I can no longer repro.

Fixed in 2.1.4.
