I tried to use sshuttle today on a fresh new CentOS 7 machine and was greeted with this error:

Traceback (most recent call last):

 raise child_exception
OSError: [Errno 2] No such file or directory
client: fatal: server died with error code 1

After a bit of digging, I realized that sshuttle requires the netstat command. I installed this with yum, and it works now:

yum install net-tools

This probably works on all RedHat variants, so if you are using RHEL, CentOS, Fedora, or Scientific Linux, this should fix the problem.
