xshell5 compression doesn't work

 
Hello,

Because i'm using 3D apps via X11 forwarding, i need the ssh compression (400 mbps to 15 mbps in this case with putty), the problem is that even if the compression button is checked in xshell (screen in attachments), the compression doesn't work and in the xshell log, it says "compression: none".

Is there another option for enabling compression ?
Is this a bug ?

Thanks in advance.

Program Ver. : Xshell 5

The default value for compression in an OpenSSH server is set to "delayed."

Change this value to "yes" in your server's sshd_config file. Then restart the sshd daemon. This should enable the compression.

Hello,

Thanks for your tips, it works. However, modify the sshd_config wasn't required by others ssh clients (ssh compression worked just by enabling the checkbox on the client side), how do you explain this ?

Re: xshell5 compression doesn't work

 
In light of your issue, we've discussed internally about how Xshell should behave when the ssh server is set to delayed compression. We've come to the conclusion that our current behavior is incorrect and the behavior you desire is the right way to go.

We're conducting a few tests and barring any major setbacks, the "correct" behavior should be rolled out with the next build release.

Thanks!
