sshuttle gives public key error about sshuttle

[NgoHuy]

@chanmratekoko you ran it successfully, but error with iptables iptables: Bad rule (does a matching rule exist in that chain?). check your iptables, when using sudo, your home was changed to root which did not have your key in /root/.ssh that all.

because user root does not have your user key in .ssh folder. preauth sudo with any command like: sudo ls then run as normal user, not sudo, it should work.

I don't understand. I am invoking the command as "myuser" and not as root.

sshuttle -e 'ssh [email protected] -p 2224' -r [email protected]:2224 0.0.0.0/0 --dns

Am I misunderstanding you? Thanks for your time.

option -e only for choosing ssh or other command, not included options like myuser@host, remove it after you run sudo something, sshuttle need sudo permission to active iptables/nftables

I guess I'm stupid for not understanding. How do I revise that code I gave? Tks

reproduce:
sudo ls
sshuttle -r [email protected]:2224 0.0.0.0/0 --dns

Hello! @NgoHuy

I have the same error after following your instruction.

reproduce: sudo ls sshuttle -r [email protected]:2224 0.0.0.0/0 --dns

sudo ls 
sshuttle -r [[email protected]](mailto:[email protected]):2224 0.0.0.0/0 --dns

Error :

Then, When I tried with 'sudo'.

sudo sshuttle -r [[email protected]](mailto:[email protected]):2224 0.0.0.0/0 --dns

Error :

Permission denied (publickey).
c : fatal: c : failed to establish ssh session (2)

Thanks for your prompt response. @NgoHuy

I use it on Windows 11 WSL2 "Ubuntu 22.04.2 LTS". But above error occurs.

I was successfully used it on Window 10 WSL2 "Ubuntu 20.04 LTS".

I think, It could be related with iptables. and permissions.
