Ruslan,

Unfortunately the SDA callouts don't show the actual information used in
figuring out when to send a keepalive packet. The default value for when to
send a keepalive packet would be the drop idle time * 5 seconds, so you have
to wait at least 5 minutes to see if a keepalive is sent.

Hi, Richard!

From the docs:

BG_TCP Parameters and Values
BG_TCP DROP_TIMER seconds
Maximum number of *seconds* to probe for idle TCP connections before a
TCP connection close
times out.
BG_TCP PROBE_TIMER seconds
Number of *seconds* between probes for idle TCP connections. Also
indicates the maximum number
of seconds before a TCP connection request times out.

I spend 10+ minutes in hope that will catch keepalive checking.

probe idle 15 Drop idle 60

Ruslan,
Unfortunately the SDA callouts don't show the actual information used
in figuring out when to send a keepalive packet. The default value
for when to send a keepalive packet would be the drop idle time * 5
seconds, so you have to wait at least 5 minutes to see if a keepalive
is sent.

Hi There! It's me again....
Thanks to Richard for TW SDA... So, now I see that KeepAlive options is set for
the socket, but actualy KeepAlive does not checking.

Hi!
Sorry ladies and guys, it's a bug/feature in the HP SSL, I suspect so ...
