Remote ssh forwarding fails [ssh: rejected: administratively prohibited] about reverse_ssh HOT 10 CLOSED

What a speed, yeah, sure

I've tried ssh -R 15151:127.0.0.1:15151 -J ..., also tried on 0.0.0.0, then in the terminal window I just accessed port 15151 with curl http://127.0.0.1:15151

Those are server logs since the moment of client connection till the error

Regarding the dying server connection, I think that's probably bc I forcefully closed open RSSH terminal session bc it hangs my terminal after the WARNING: Server requests forwarding for unknown listen_port, but I believe it's just a terminal issue and has nothing to do with RSSH

from reverse_ssh.

Ah cool I've fixed it. Give me one moment and I'll do a release

from reverse_ssh.

Howdy.

Can you also give me the ssh command you used to get this error?

Definitely off that the server connection is dying for the client.

Could you give me server logs for this?

from reverse_ssh.

Cool I can replicate this. Not sure how its broken yet.

from reverse_ssh.

Is it global or happens only on specific OpenSSH client versions? I've searched yesterday and found kinda similar issue with remote forwarding, for the guy there it was broken on 7.9 or smth like that but on 5.5 it worked as expected, didn't test lower client versions tho' and it was about normal ssh server, not RSSH. Maybe there are minor changes in OpenSSH forwarding logic

Will try to find it again if needed

from reverse_ssh.

Actually, I may have to take that replication back. Turns out I've found another weirdness when you dont define localhost as 127.0.0.1 on a machine it can cause failure to open.

from reverse_ssh.

Ah no I can, its just a little different then I first thought

from reverse_ssh.

I've tried ssh -R with [PORT]:[localhost/127.0.0.1/0.0.0.0/other interface IP]:[PORT], didn't work for all cases, the last server log is for ssh -R 15151:127.0.0.1:15151

from reverse_ssh.

Oh jeez, you're awesome, thanks for such a quick response and fix, and for such an amazing tool

from reverse_ssh.

All done!
