OpenSSH_3.4p1 Debian 1:3.4p1-1
Die Absaetze aus 'man ssh_config' :
KeepAlive
Specifies whether the system should send TCP keepalive messages
to the other side. If they are sent, death of the connection or
crash of one of the machines will be properly noticed. of the
machines will be properly noticed. This option only uses TCP
keepalives (as opposed to using ssh level keepalives), so takes a
long time to notice when the connection dies. As such, you prob
ably want the ProtocolKeepAlives option as well. However, this
means that connections will die if the route is down temporarily,
and some people find it annoying.
The default is ``yes'' (to send keepalives), and the client will
notice if the network goes down or the remote host dies. This is
important in scripts, and many users want it too.
To disable keepalives, the value should be set to ``no''.
ProtocolKeepAlives
Specifies the interval at which IGNORE packets will be sent to
the server during dile periods. Use this option in scripts to
detect when the network fails. The argument must be an integer.
The default is 0 (disabled), or 300 if the BatchMode option is
set.
Ich denke mal, dass das Sekunden sein sollen (das steht naemlich nicht
da, aber die 300 deutet auf 5 Minuten hin).
