      Description

      We have a Spectra Logic storage box here and the remote console uses SSH but with a restricted shell, not a standard shell (sh/bash/whatever). When attempting to connect, guacd stalls and never returns (or I wasn't patient enough to wait several minutes). This was working in 0.9.8. If I read correctly changes were made in 1.1.0 to interrogate the remote SSH server for stuff like the shell used, setting the TZ and locale.

      All our old connections have been redone in the configuration and work seamlessly except this one.  SSH connections with 'normal' OpenSSH servers are working perfectly. Pretty sure that this new handshake is not working in this context. How should I investigate this and is there a way to revert to the old behavior ?
