SSH - size and colors of canvas

[David Česal <Da...@Cesal.cz>]

Hello,

 

I'm using official JavaScript code and connecting to SSH. Is it possible to:

 

*	change width/height of canvas
*	change colors of terminal?

 

I was able to find only this thread -
https://sourceforge.net/p/guacamole/discussion/1110833/thread/97fc1c6b/ .
GUAC-1195 is done, but doesn't have any other information.

 

I've tried to change colours with setterm, but they are too dark. I
understand that colors are given by server; are there any configuration
parameters to set this?

 

For canvas size, I'm trying to give width and height parameters to
GuacamoleSocket, but it's always 1024 x 768.

 

Thank you

David

Yes. When connecting, the initial width/height is dictated by the
width/height passed during the Guacamole protocol handshake via the
GuacamoleClientInformation object given to the
ConfiguredGuacamoleSocket:

http://guacamole.incubator.apache.org/doc/gug/guacamole-protocol.html#guacamole-protocol-handshake
http://guacamole.incubator.apache.org/doc/guacamole-common/org/apache/guacamole/protocol/GuacamoleClientInformation.html
http://guacamole.incubator.apache.org/doc/guacamole-common/org/apache/guacamole/protocol/ConfiguredGuacamoleSocket.html

While the connection is active, the display size can be changed
through sending a "size" instruction:

http://guacamole.incubator.apache.org/doc/gug/protocol-reference.html#size-event-instruction
http://guacamole.incubator.apache.org/doc/guacamole-common-js/Guacamole.Client.html#sendSize

Yes, through connection parameters. See the "color-scheme" parameter:

http://guacamole.incubator.apache.org/doc/gug/configuring-guacamole.html#ssh-display-settings

The same parameter is also provided for telnet:

http://guacamole.incubator.apache.org/doc/gug/configuring-guacamole.html#telnet-display-settings

If you're trying to set the width and height through specifying
"width" and "height" connection parameters, this will not work. There
are no such parameters for SSH:

http://guacamole.incubator.apache.org/doc/gug/configuring-guacamole.html#ssh

The initial width and height of the display for both SSH and telnet is
set through the optimal width/height provided during the Guacamole
protocol handshake (see above).
