SSH connection error segfault
Hi,
I cannot connect to SSH-server via Guacamole. Into the private key I pasted
contents of rsa.ppk file:
> PuTTY-User-Key-File-2: ssh-rsa
> Encryption: none
> Comment: rsa-key-20170717

> XXXXXXXXXXXXXXXXsomethingXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX

Public key: ssh-rsa
AAAAB3XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX
Connection via Putty *goes fine*. In the guacd log I got this:

But the issue is gone after I converted the private key, so I assume it was
related to key format. Now I don't see any segfaults.

0.9.13 is not out yet, correct, however the issue you describe should
be fixed on git. If you're willing to deploy a build from recent git,
that would help determine whether you are encountering something new.

0.9.12. AFAIK, 0.9.13 version is still in beta state.

Correct, that helped. Thanks for the clarification.
BTW, could you please say smth about this SSH error
<http://apache-guacamole-incubating-users.2363388.n4.nabble.com/Cannot-connect-to-SSH-XMT-Solicit-on-eth0-td1315.html>
? It's really interesting.

You will need to convert the PPK file into standard PEM format. Only PuTTY
can read its PPKs.

There was a recent issue which was fixed that would result in a segfault
upon disconnect for SSH connections:
https://issues.apache.org/jira/browse/GUACAMOLE-257
Can you confirm which version of Guacamole you are using?
