connect to the centos from windows machine.

[ keymap setting ]

I can’t enter underscore via NX session

to solve this , edit .xmodmap file.
$ xmodmap -pke > .Xmodmap

add the “backslach underscore” in keycode 123.
$ egrep 123 ~/.Xmodmap
keycode 123 = backslash underscore

terminate NX session and connect again
You could enter underscore.

If you want to start freenx-server when booting the OS , configure system services with chkconfig command like this:

# chkconfig freenx-server --list
freenx-server   0:off   1:off   2:on    3:on    4:on    5:on    6:off

# chkconfig freenx-server off
# chkconfig freenx-server on
