# TCP keepalive.
#
# When this option is set to a non-zero value, SO_KEEPALIVE option will be
# enabled in order to send ACKs just to avoid connection drops or to detect
# dead peers.
# If non-zero, use SO_KEEPALIVE to send TCP ACKs to clients in absence
# of communication. This is useful for two reasons:
#
# The value you specify with this option is the period (in seconds) we use
# in order to refresh the connection with TCP ACKs, however the period is
# only actually set on Linux. Other kernels will use the system-wide default.
# 1) Detect dead peers.
# 2) Take the connection alive from the point of view of network
# equipment in the middle.
#
# On Linux, the specified value (in seconds) is the period used to send ACKs.
# Note that to close the connection the double of the time is needed.
# On other kernels the period depends on the kernel configuration.
#
# A reasonable value for this option is 60 seconds.
