I have installed Xming successfully on a Windows XP system.
It works OK to a FC6 system and an older UNIXware system.
However when trying to connect to a FreeBSD 6.2 system with PuTTY
ssh it doesn't work. PuTTY has Enable X11 forwarding checked.
Here's what I get:
$
$ xhost
Xlib: connection to "localhost:10.0" refused by server
Xlib: PuTTY X11 proxy: wrong authentication protocol attempted
xhost: unable to open display "localhost:10.0"
$
What can be wrong?
I have ssh configured as follows:
# grep X11 /etc/ssh/*
/etc/ssh/ssh_config:ForwardX11 yes
/etc/ssh/ssh_config:ForwardX11Trusted yes
/etc/ssh/sshd_config:X11Forwarding yes
/etc/ssh/sshd_config:X11DisplayOffset 10
/etc/ssh/sshd_config:X11UseLocalhost yes
Here is the Xming log file:
