TCP proxy usage

[morphin]

Hello.

We have a custom TCP proxy and we would like to grab our Ticket in connection process to redirect the client to the server.

I’ve tried NX http proxy settings and I wrote our Ticket in “Http proxy Username” section and I can grab the ticket as I desired but I don’t want to use http proxy. I can redirect any connection If I can take the Routing information from Ticket. The ticket has IP, Username, Unique one time Ticket.

So the question is: How can I write custom Ticket in NX connection file and read the Ticket on TCP proxy?

Hello,
In order to allow us to investigate, can you tell us more about your configuration?

Thanks for the answer Tom!

To simplify my question: I’m looking for something like “loadbalanceinfo:s:tsv” windows RDP parameter.

Hello morphin,

I am not sure of the product you are using, but did you try NoMachine Cloud Server ?

Indeed it can act as some kind of proxy for the NX connections: NoMachine – Secure remote access and reliable desktop delivery across any data center or cloud

You can download an evaluation version of the software to test it.

Hello Bilbotine.

I don’t use any product for proxy. I have my own Remote Desktop Gateway proxy written in go. I’m using it for RDP and I have my own Ticket system. The only thing that I need is sending the ticket from nx client to the destination and grab it from first 10-50byte data.
I can do that with writing the ticket in http-proxy username line but when I enable the http proxy Nx player throws an error because I use TCP proxy and I really don’t wanna set up http proxy (its easy, I can but I dont want to.)
There is SOCKS option but I couldn’t find any doc about it.

So my question is very easy: Is there anyway to send some data in first 0-100 byte or do you have TCP proxy option?

Hello morphin,

There is no way to include arbitrary data into first part of connections. However if you don’t want to use HTTP proxy a SOCKS proxy can be a good alternative, since it works with TCP connections.

Please refer to the following links:

rfc1928 (ietf.org)

Yes Socks proxy will be answer but there is no doc or reference page for about it. Is it possible to use SOCKS proxy in connection file?

[Bilbotine]

Hello morphin,

Yes, it’s possible to use SOCKS proxy in the connection file; however in version 7.X, the connection file has to be eddied manually.

The following values have to be set:

<option key=”Enable HTTP proxy” value=”true” />

<option key=”HTTP proxy host” value=”hostname” />

<option key=”HTTP proxy port” value=”8080″ />

<option key=”HTTP proxy password” value=”password” />

<option key=”HTTP proxy username” value=”username” />

<option key=”Remember HTTP proxy password” value=”false” />

<option key=”Manual proxy configuration type” value=”socks” />

<option key=”Proxy configuration mode” value=”manual” />

 

In the upcoming version 8.X, it will be possible to set all these fields in the GUI.

Please let us know if this answer helps you!
