OK, entón como puxen 60 non son os minutos, se non que
cada 60 segundos
envíase un paquete para ter viva a conexión, que é menor dos 2 minutos que
tarda en desconectar por inactividade. Agora teño terminal perpetua e tal
vez sexa bo poñer TMOUT a 3600 para sair nunha hora...
Sacado del mismo sitio... por si te interesa controlarlo todo desde el
mismo fichero:
ClientAliveCountMax
Sets the number of client alive messages (see below) which may be
sent without sshd(8) receiving any messages back from the client.
If this threshold is reached while client alive messages are
being sent, sshd will disconnect the client, terminating the
session. It is important to note that the use of client alive
messages is very different from TCPKeepAlive (below). The client
alive messages are sent through the encrypted channel and
therefore will not be spoofable. The TCP keepalive option
enabled by TCPKeepAlive is spoofable. The client alive mechanism
is valuable when the client or server depend on knowing when a
connection has become inactive.
The default value is 3. If ClientAliveInterval (see below) is
set to 15, and ClientAliveCountMax is left at the default,
unresponsive SSH clients will be disconnected after approximately
45 seconds. This option applies to protocol version 2 only.
Saludos.
