ubuntu 13.04 64bit : install xrdp

Remote desktop server : ubuntu 13.04 64bit

Client : windows XP Pro

root@ubuntu-1:~# tail -1 /etc/lsb-release DISTRIB_DESCRIPTION="Ubuntu 13.04" root@ubuntu-1:~# uname -ri 3.8.0-19-generic x86_64

Install xrdp

# apt-get install xrdp

Start xrdp

# /etc/init.d/xrdp start * Starting Remote Desktop Protocol server

Remote desktop clients usually connect to RDP server with TCP 3389.

So the XRDP server would open TCP 3389.

# lsof -ni:3389 COMMAND   PID USER   FD   TYPE DEVICE SIZE/OFF NODE NAME xrdp    15184 xrdp    6u  IPv4 155266      0t0  TCP *:3389 (LISTEN)

On the windows XP box , start remote desktop client and connect to the server.

nnn , error , can’t connect.

login users need to belong to a group “xrdp”

add my account “foobar” in xrdp group

usermod -G groupA,groupB….xrdp <user name>

root@ubuntu-1:~# usermod -G foobar,root,fuse,libvirtd,x2gousers,xrdp foobar root@ubuntu-1:~# egrep xrdp /etc/group xrdp:x:144:foobar

restart xrdp

# /etc/init.d/xrdp restart

try again!

Okay , I can connect to the server.

[ 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.
