Host A: Ubuntu Desktop box running at graphical runlevel. Sitting in office. /etc/ssh/sshd_config "X11Forwarding yes"
Host B: Windows laptop running Cygwin/X. Can run X clients locally. VPN from Host B into office network. Can ssh from Host B to Host A. Want to display X clients on laptop.
From laptop:
xhost +
ssh -X mmartinez@hostA xclock
Warning: untrusted X11 forwarding setup failed: xauth key data not generated
Error: Can't open display:
UPDATE: as per Michael Hampton's comment, using ssh -Y mmartinez@10.10.10.165 xclock works.
