[Xymon] Fix for RDP tests

[Rob Steuer]

Hi Ryan –

 

I tested with Windows 2003 server successfully.  Anything older really shouldn’t be in operation anymore anyway.

Is it possible that this makes the test not work for older RDP servers?

Hi Rob,

It works perfect here.

Using Xymon 4.3.21 with both 2008 / 2008 R2 / 2012 / 2012 R2 with no

issues at all.

 

Thanks for the update, I'll deleted the RDPNLA witch was the approach I

did to get it to work.

 

I'll too backup on the protocols.cfg updates in the next release.

Emne: [Xymon] Fix for RDP tests

 

Hi,

 

After trying to implement the RDP tests for monitored hosts I noticed that

they were returning a yellow warning with the warning text "Unexpected

service response".  I tried this for older hosts running Windows 2003 and

newer hosts running 2008/2012 with RDP using NLA.  It gave the warning

text for both.  So I'm guessing the original rdp test was implemented many

years ago (2010 per below) when things were handled differently.

 

The specification currently in the protocols.cfg file for RDP as it stands

today is as follows:

 

# Microsoft Terminal Services / Remote Desktop Protocol

# From Chris Wopat (http://www.xymon.com/archive/2010/01/msg00039.html)

[rdp]

               port 3389

               send "\x03\x00\x00\x1e\x19\xe0\x00\x00\x00\x00\x00Cookie:

mstshash=\r\n"

               expect "\x03\x00\x00\x0b\x06\xd0"

 

I couldn't find anyone who provided a true fix in the archives other than

suggesting doing a network trace.  So that's what I did.  After a bit of

testing I found the following to work:

 

# Microsoft Terminal Services / Remote Desktop Protocol

# From Chris Wopat (http://www.xymon.com/archive/2010/01/msg00039.html)

# Updated By Rob Steuer 10-17-2015 with send and expect strings that work

for current versions of RDP

 

[rdp]

               port 3389

               send

"\x03\x00\x00\x13\x0e\xe0\x00\x00\x00\x00\x00\x01\x00\x08\x00\x0b\x00\x00\x00"

               expect "\x03\x00\x00\x13\x0e\xd0\x00\x00\x12\x34"

 

I was tempted to rename the protocol test to [rdpnla] or something like

that to keep the old one around, but really the old one just didn't work

for anything, so IMHO I think it just needs to be replaced entirely.

 

I'd like feedback from others to see if this works for them also and see

the protocols.cfg updated in the next release of Xymon.

 

Thanks!

Rob



Hi Rob,

I can confirm it's working for me as well. Thanks for the submission! It's
