ssh2_keepalive_config — Configure how often keepalive messages should be sent
Configures how often keepalive messages are sent on the given
session, and whether the server is asked to reply to
them.
Keepalive messages are not sent automatically. Once configured, ssh2_keepalive_send() must be called to actually send a keepalive message.
Bilginize:
This function is only available when the extension is built against a libssh2 version providing keepalive support.
sessionAn SSH connection link identifier, obtained from a call to ssh2_connect().
want_replyWhether the server is requested to reply to keepalive messages. Requesting a reply makes an unresponsive server detectable, at the cost of some extra traffic.
interval
The number of seconds that may pass without any traffic before a
keepalive message should be sent. A value of 0
disables keepalive messages, and a value of 1 is
treated as 2 by the underlying library.
Accepted values range from 0 to
4294967295.
Hiçbir değer dönmez.
An E_WARNING is emitted when
interval is outside the accepted range, in which
case the keepalive configuration is left unchanged.
