> Hi all,
> I am using guacamole 0.9.14 and libssh2-1.9.0.
> it is working well without any issue till now.
> Recently, the application team they have updated the patch on their system.
> So after that, we were not able to do ssh to their systems using guacamole.
> Whereas when we try to login using OpenSSH (putty or login from linux system
> ) is working
> So i checked and found only the below mentioned key exchange methods are
> allowed on remote Linux systems.
> *"curve25519-sha...@libssh.org,ecdh-sha2-nistp521,ecdh-sha2-nistp384,ecdh-sha2-nistp256"*
> But all these key exchange methods are not supported by libssh2. Whereas it
> is supported on libssh.
> Libssh key exchange methods.

> so is there any option to choose libssh instead of libssh2 while installing?
> Or suggest me some good ideas to rectify this issue.
