# So in this case we have 21564 orphans. That doesn't seem very close to 65536... Yet, if you look once more at the code above that prints the warning,
# you'll see that there is this shift variable that has a value between 0 and 2, and that the check is testing if
# (orphans << shift > sysctl_tcp_max_orphans). What this means is that in certain cases, the kernel decides to penalize some sockets more, and it does
# so by multiplying the number of orphans by 2x or 4x to artificially increase the "score" of the "bad socket" to penalize. The problem is that due to
# the way this is implemented, you can see a worrisome "Out of socket memory" error when in fact you're still 4x below the limit and you just had a
# couple "bad sockets" (which happens frequently when you have an Internet facing service). So unfortunately that means that you need to tune up the
# maximum number of orphan sockets even if you're 2x or 4x away from the threshold. What value is reasonable for you depends on your situation at hand.
# Observe how the count of orphans in /proc/net/sockstat is changing when your server is at peak traffic, multiply that value by 4, round it up a bit
# to have a nice value, and set it. You can set it by doing a echo of the new value in /proc/sys/net/ipv4/tcp_max_orphans, and don't forget to update
# the value of net.ipv4.tcp_max_orphans in /etc/sysctl.conf so that your change persists across reboots.
# ----------------------------------------------------------------------------------------------------------------------------------------------------------
# A server that uses SYN cookies doesn't have to drop connections when its SYN queue fills up.
# Instead it sends back a SYN+ACK, exactly as if the SYN queue had been larger.
# (Exceptions: the server must reject TCP options such as large windows, and it must use one of the
# eight MSS values that it can encode.) When the server receives an ACK, it checks that the secret
# function works for a recent value of t, and then rebuilds the SYN queue entry from the encoded MSS.
