Subject Re: Using the SSH client
Date Tue, 06 Sep 2016 20:32:11 GMT
<p style="font-family:open sans,sans-serif; font-size:12px; margin: 0;">Thanks for your
reply, but i figured out what the problem was. &nbsp;The box that guacample is on has
two version of OpenSSL, a compat version and the latest version. &nbsp;It turns out the
guacd was picking up the compat version and the ssh client library was picking up the new
one. &nbsp;Once i fixed my setup where both were picking up the latest OpenSSL, it worked
just fine.</p>

is not supported as far as I know.</p>

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

<div>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?</div>
