Hi, I've installed debian 6 in a jail, from FreeBsd 9.1 x86-64 by following the instructions from this thread. However, I also updated my /etc/resolv.conf inside the jail, but I get this error when I do ping:


server# /etc/rc.d/jail start debian
Configuring jails:.
Starting jails: debian.


server# jls
   JID  IP Address      Hostname                      Path

server# jexec 13 bash

Apart from getting those ping errors, I cannot "apt-get update":

root at debian:/# apt-get update

E: Sub-process http returned an error code (100)

I need apt-get to install g++, to be able to compile a linux c++ app from FreeBsd.
