ssh to tweenex.org

[Stéphane Tsacas]

Thank you for all the answers.
It seems that waiting a day or so solved the problem, and now ssh doesn't
ask for tweenex password and act like a pass thru, as documented.

One explanation why we see 2 adresses might be because the first one is the
proxy/pass thru server, and the second one the host :
 ssh -v twenex at sdf.org
OpenSSH_7.7p1, OpenSSL 1.0.2o  27 Mar 2018
debug1: Reading configuration data /etc/ssh_config
debug1: Connecting to sdf.org [205.166.94.16] port 22. // proxy (pass thru)
server
...
Authenticated to sdf.org ([205.166.94.16]:22).
debug1: channel 0: new [client-session]

debug1: Entering interactive session.

Connected to 205.166.94.130. // host address
Escape character is 'off'.
