Remmina and RDP

**ttoolin** · June 11th, 2012

I am using almost clean installs of ubuntu 12.04 on two machines. T am trying to get RDP to work, using Remmina. I plan on adding a Windows computer to the mix, later.

VNC works fine. RDP doesn't work at all - just 'unable to connect'.

Thescarce instructions I can find suggest this is no-hassle, so it seems like I just need to toggle some setting the other way, or something simple like that.

Please help.

Thanks.

On the server side, you can

1. make sure the xrdp / sessman services are running

Code:

$ service xrdp status
 * Checking status of Remote Desktop Protocol server xrdp                                                                                                                   [ OK ] 
 * Checking status of RDP Session Manager sesman                                                                                                                            [ OK ]

2. use netstat to check the services are bound to the expected ports

Code:

$ sudo netstat -nlpt | grep xrdp
tcp        0      0 127.0.0.1:3350          0.0.0.0:*               LISTEN      3995/xrdp-sesman
tcp        0      0 0.0.0.0:3389            0.0.0.0:*               LISTEN      3993/xrdp

3. check whether the server side firewall is enabled and if so whether it is allowing incoming connections for those ports

Code:

$ sudo ufw status
Status: active

To                         Action      From
--                         ------      ----
22/tcp                     ALLOW       192.168.1.0/24
3389/tcp                   ALLOW       192.168.1.0/24
3350/tcp                   ALLOW       192.168.1.0/24

On the client side you can use telnet or nmap to make sure the port is reachable

Code:

$ telnet 192.168.1.12 3389
Trying 192.168.1.12...
Connected to 192.168.1.12.
Escape character is '^]'.
^]


$ sudo nmap -p 3389 192.168.1.12

Starting Nmap 5.21 ( http://nmap.org ) at 2013-04-11 17:19 UTC

Thnx for fast replay to start with.
Oncle Google this time didnt understand my question -thats why I bumped this thread.

I add that, in win7 "Remote desktop" connects server (work). So server is up and running - no problems at all.
I made update to (L)ubuntu, but it didnt change any better, only some problems. Im going to reinstall OS, it can take some time to make this (also all the "apt-get install") and to troubleshoot rooting/connection problems.
I add that Remmina can identify server (i think?), because it gives me server certificate, which I dont know how to interpretate (I remember it had "fingerprint:").

Have you got it set up to use SSH tunneling by any chance? it sounds like the server is presenting its host cert and asking if you want to add it to your known_hosts file

Code:

service xrdp status

gives:
xrdp: unrecognized service

Code:

sudo netstat -nlpt | grep xrdp

gives:
nothing...

should I continue?

edit:
Thats interesting. I have another older rig, that has Lubuntu 11.10 on it at it has no problems at all connecting with Remmina GUI.

edit 2 [SOLVED]:
This what resolved my problem: here (Right click, Edit ...Click Advanced tab in your Remote Desktop Preferences and choose RDP in Security drop down menu and save.)

I must say that before that I did also

Code:
