Condorello commented 10 years ago

Hi, I can't use x11rdp, here the sesman log:

[20140319-19:56:55] [WARN ] [init:46] libscp initialized [20140319-19:56:55] [CORE ] starting sesman with pid 514 [20140319-19:56:55] [INFO ] listening...

everything works fine if i use x11vnc. I compilate latest git without errors on centos 6. I cannot find more info about this error in any logs, someone can help me? Thanks in advance.

First, make sure you can run X11rdp at a command prompt. X11rdp :15 and see what happens.

Uhm it seems something related to sesman/svc. Try to run sesman in foreground and have a look to the stdout.

Hello, its a sesman error, means unrecognized sesman control protocol version. what xrdp version do you use? Did you build it from sources? What distro do you use?

Condorello commented 10 years ago

Hi, thanks for your reply. I’m on Centos6 x64 and i compiled everything from this git source.

iv'e tested master on my centos 6.5 64bit box everything seems ok.

I recommend you to do 'make uninstall' and walk through our guide: http://www.xrdp.org/index.php?option=com_content&view=article&id=14:building-on-centos-5x&catid=2:documents&Itemid=7

I did everything again, though i followed those instructions before, but still get the same error in the logs:

I’m on a openVZ vps, my centos has the openvz custom kernel. Could be here the problem, something like a module? But during the compiling everything went fine without any error. :/

  1. xrdp-sesman's pam''s config file is different for centos so after installation, do that: sudo cp /instfiles/pam.d/xrdp-sesman.other /etc/pam.d/xrdp-sesman

you should create a rsa key file (rsakeys.ini) file using xrdp-keygen tool: sudo xrdp-keygen auto xrdp (it should create an rsakeys.ini in /etc/xrdp ) — Reply to this email directly or view it on GitHub.

Hello,

xrdp and sesman communicate through local uds socket, located in /etc/.xrdp

I dont know openVZ , thus, I cant say if it is related to it. On Mar 23, 2014 12:32 PM, "Condorello" notifications@github.com wrote:

it's internal with the scp protocol, but it's not documented very well. I have just found this and nothing more:

case SCP_SERVER_STATE_VERSIONERR: /* an unknown scp version was requested, so we shut down the / /_ connection (and log the fact) */ log_message(&(g_cfg.log), LOG_LEVEL_WARNING, "unknown protocol version specified. connection refused.");

xrdp_mm.c should send the version. But it may change into scp process . On Mar 23, 2014 1:43 PM, "Condorello" notifications@github.com wrote:
