Hi, At work I have been using ssh for X connections between FreeBSD an linux=20 machines without problems. Meanwhile X connections to a HP machine 'HP-UX hphendon B.10.20 A 9000/735'= =20 on the network have been established using classical 'rsh' with 'xhost' authentication because the HP-UX system did not have ssh installed. I recently installed openssh-3.7.1p2 on the HP and as a simple terminal=20 connection this seems to work OK. But if I try to tunnel X through ssh I have problems -- the connection is rejected. =46rom one of the FreeBSD machines (FBSD 4.9) issuing the command: $ ssh -v -X -f hphendon xterm yields debug information including the following lines:- debug1: client_input_channel_open: ctype x11 rchan 2 win 65536 max 16384 debug1: client_request_x11: request from 127.0.0.1 1419 debug1: fd 4 setting TCP_NODELAY debug1: fd 4 setting O_NONBLOCK debug1: channel 1: new [x11] debug1: confirm x11 debug1: X11 connection uses different authentication protocol. X11 connection rejected because of wrong authentication. debug1: X11 rejected 1 i0/o0 I assume "X11 connection uses different authentication protocol" is at the core of the problem -- but what does it really mean? Is there a way around the problem? Must I go back to the classical insecure xhost approach? Yes, I did enable X11 in sshd_config on the HP. X on the HP is based on "X consortium" rather than "XFree" -- can this be significant? An X connection can be established in the other direction without problem. I would appreciate any thoughts on this matter. Malcolm Kay
