I am trying to run sshuttle on an ARMv6 but if fails as shown in the below. I ran the command with and without 'sudo' but no luck.

Code:
 s: <  channel=0 cmd=PING len=7

Never used it before but looking at the errors I'm assuming you need to configure it. It appears to be trying something with iptables, which only works on Linux.

Thanks.
I got it working by adding the user running sshuttle to the wheel group. I am now more worried about sshguard repeatedly adding my IP address to its blacklist despite that I have added the IP addr block to the sshguard.whitelist file. This matter makes me go back to the rescue mode to remove the IP addr from the blacklist.

Interestingly, the IP address gets added to the blacklist every time I sshed via the ARM board, in addition sshing via the other PC(s).
