However you could enable tcp level keepalives and on
linux you can tune
the intervals, e.g.:
tcp_keepalive = yes
tcp_keepidle = 60
tcp_keepintvl = 10
tcp_keepcnt = 3
andrei,
my linux 2.6.32 kernel has these tcp keepalive variables:
tcp_keepalive_intvl tcp_keepalive_probes tcp_keepalive_time
linux tcp keepalive doc says:
Remember that keepalive support, even if configured in the kernel, is
not the default behavior in Linux. Programs must request keepalive
control for their sockets using the setsockopt interface. There are
relatively few programs implementing keepalive, but you can easily add
keepalive support for most of them following the instructions explained
later in this document.
question: does sr request that tcp keepalive is turned on on its tcp
connections or via a function call on a particular connection?
