Maybe you wait until Tramp runs into a time-out? I cannot promise | it works then, but sometimes telnet takes its time. I did enter C-g quite quick, because it was not the first failing try ... I just tried waiting more , up to 4 minutes, with the same lack of result. In addition, I do not have any connection buffer to look at. Can it be some network / firewall issue ? (which would not occur with 'raw telnet' : remember that basic telnet connection from a fresh terminal window does work; and M-x telnet do work too, and M-x shell + telnet does work too) Regards Stéphane | When the time-out occurs, it might be also interesting to see the | contents of the connection buffer (plus the Tramp debug buffer, as you | did already). | > Thanks for any help | > | > Stéphane | Best regards, Michael. -- ----- Météo-France ----- SENESI STEPHANE CNRM/GMGEC/ASTER [email protected] Fixe : +33 561079931
