Deadlock problems with send function (wodWebServer / wodWebServer.NET)

Hello,
I'm using the SSH.net component for Telnet and SSH communications.
I'm using a none blocking type, and I get very bad results when using Telnet protocol.
I have a textbox with a KeyDown event, and when ever I press a key for a few seconds (and calling the SSH.Send(..) function for each event) my main thread gets blocked.
When looking at the stacktrace, I get:

I would appreciate your quick response.

By the way, the problem does not exist when connecting with the SSH protocol.

Hi Marian,

I try to duplicate your problem but it works for me with SSH and Telnet protocol.

Is there any chance you can try our Terminal CS or Terminal VB sample in component Samples folder?

Does ti work there or you still receive your problem?

Drazen

Dear Drazen,
Sorry for replying just now, I've been working on a different project lately but now I'm back. [:happy:]

The problem occurs on the Terminal CS sample as well.
In order to reproduce the problem:
1. Make a 10MB text file on a linux machine.
2. Connect to it using Telnet
3. Execute a cat [file] command for printing the file to console
4. Press Ctrl+C for breaking the printing.

At this point the application will get into a dead lock on the SSH.Send method.

I hope you can solve this soon [:doh:]
Kind regards.
Marian

Hi Marian,

This worked for me without any problem. Can you maybe send us email to techsupport@weonlydo.com

We will send you there access to our linux server. So maybe we can try to recreate your probem there.

Drazen

I have send you an email.
Thanks for the quick response.

Hi Drazen,
I uploaded a file called bigfile.txt
and when i execute the command 'cat bigfile.txt' and press a few keystrokes while the file is printed, the application hangs.

it might not hang on the first time, but try it a few times.

Please let me know if you're able to reproduce it.
If not, I don't mind letting you remote control my pc and check for yourself.

Kind regards,
Marian.
