sshuttle to access remote networks

By following these steps you should have password less access to your remote hosts and networks via ssh and sshuttle.

Replace user with the your [user]. Put the relevant sections with configuration specific to your use case.

Configure sudo access

sshuttle --sudoers
Success, sudoers file update.

Copy users ssh key identity to targe server

ssh-copy-id  [user]@some.remote.host.com

run sshuttle to connect

sshuttle -v -r [user]@some.remote.host.com 10.0.0.0/16 10.1.0.0/16 10.2.0.0/16

There should now be no password prompt to securely access this server and the subnets it routes

Add systemd unit file to user

nvim /home/[user]/.config/systemd/user/sshuttle.service

Here is a unit template for

# /home/[user]/.config/systemd/user/sshuttle.service

Running the service

By placing this unit in your users control you can start and stop it and it will have access to your ssh-agent keys

I have a vpn that I use to connect to the host which I have to run first.

systemctl --user daemon-reload
systemctl --user start sshuttle.service

To confirm every thing is working correctly

journalctl --user -u sshuttle.ct.service -f
