Update: I completely removed Cygwin, and reinstalled it (broadband is so nice :)
I still have the same "different auth protocol" message when connecting. My "server" (actually that's client, isn't it? :-) the Linux box, has X11 forwarding enabled in /etc/sshd/sshd_config: Port 22 Protocol 2,1 StrictModes no #(was yes; I tried both) X11Forwarding yes On my Win2k Cygwin install, I run "xhosts +". I've also tried connecting to the Linux box using regular users, not just root. The command I issue is: ssh -v -l scott mylinuxbox.foo.com -X Hmm. -----Original Message----- From: Scott Prive Sent: Tuesday, October 30, 2001 5:50 PM To: Cygwin-Xfree (E-mail) Subject: cygwin xfree86 & ssherror : X11 connection uses different authentication protocol Hello, Attempting to forward X11 without much success. My local system is a Windows 2000 PC running the very latest Cygwin binaries, plus the xfree86 binaries. Xfree is running great locally under Windows. My Linux server - which is on a different subnet - is a Red Hat 7.2 system running XFree86. There is no firewall between the client and the server. The Linux server runs X11 just fine locally, My steps: 1) From a local cygwin shell on NT, I run "startxwin.sh" and X starts with a term. 2) ssh -v -l root mylinuxbox.foo.com -X (ssh version is what comes with Cygwin and is very recent) 3) Attempt starting an X11 app on the Linux box, such as "xeyes" or "kwrite", and I get the following info: [root@zaphod /root]# xeyes debug1: client_input_channel_open: ctype x11 rchan 2 win 4096 max 2048 debug1: client_request_x11: request from 192.168.100.21 35785 debug1: fd 8 setting O_NONBLOCK debug1: channel 1: new [x11] debug1: confirm x11 debug1: X11 connection uses different authentication protocol. debug1: X11 rejected 1 i1/o16 debug1: channel 1: read failed debug1: channel 1: input open -> drain debug1: channel 1: close_read debug1: channel 1: write failed debug1: channel 1: output open -> closed debug1: channel 1: close_write debug1: X11 closed 1 i2/o128 In particular, the "X11 connection uses different authentication protocol" seems to imply a software/configuration issue, but I am surprised because Cygwin/Windows to Linux (RH) must be very common. Any help is most appreciated! Thanks! Scott Prive
