Using the SSH client

Hello.

I am using guacamole 0.9.9 on a CentOS 6.8 box, with a custom front
end.  RDP and VNC work fine.  I am having trouble with SSH.  When i
try to connect, i get the prompts for username and password, but then
it disconnects.  This is what guacd outputs:

guacd[6285]: INFO:      Protocol "ssh" selected 

guacd[6285]: INFO:      Connection ID is
"$d3ed8125-6faf-4610-9fa5-90486460dd2b" 

guacd[6285]: INFO:      Starting client 

guacd[6285]: DEBUG:     Starting input thread. 

guacd[6285]: DEBUG:     Starting output thread. 

guacd[6285]: DEBUG:     Ignoring unknown keysym: 0xFFE2 

guacd[6285]: DEBUG:     Successfully connected to host _xxx._

_, port 22
 

guacd[6285]: ERROR:     SSH handshake failed. 

guacd[6285]: DEBUG:     Input thread terminated. 

guacd[6285]: DEBUG:     Output thread terminated. 

guacd[6285]: INFO:      Client disconnected

I am able to ssh into the box from the server without any problems.
Has anyone seen this issue before, or can recommend a place i can
start debugging this?

thanks,
adamtg

I had a similar issue that turned out to be a key algorithm mismatch. ECDSA
is not supported as far as I know.
