>Environment:

4.1-STABLE
OpenSSH sshd
laggy network with very slow DNS reverse lookups

>Description:

On slow networks, the default 60 second timeout for authentication can be too
low to allow a connection to actually take place.  Given that a lot has to
happen in that 60 seconds, high latency or packet loss can prevent negotation
from reaching a useful point.  It is also the case that with a one-time
password scheme with a trusted keying device, additional time is required to
perform the authentication.

>How-To-Repeat:

DUMMYNET

>Fix:

Increase default timeout to 120 or more seconds.
