[ale] SSH hangs

[Christopher Fowler]

I've configured 2 servers to communicate via on demand dial-up PPP
links.  telnet, http, ping, etc work fine but ssh hangs.  The minute I
execute the ssh command the modem dials but ssh hangs forever.  On top
of that pppd terminates and dials back due to inactivity.  Apparently
from the keepalive probes.
