comment Unix socket connection limit
A statement like "domain sockets are not as scalable as network sockets" sounds like rubbish to me. I think results would depend greatly on workload and configuration. With a quick Google search I could find actual tests done which showed no difference for one person, and which showed domain sockets were faster than network sockets for another person. You don't seem to have any actual problem and show no evidence of approaching a scalability barrier. You're asking for "just in case" tuning for a problem you haven't hit yet.

comment KVM bridging for virtual machines is not working
Show us each of the files in /etc/sysconfig/network-scripts/ifcfg-*, the output of ip addr instead of ifconfig, cat /proc/net/bonding/bond0, and brctl show

More information could be provided by using ip address instead of ifconfig. Don't use ifconfig anymore, it's deprecated and useless.

comment Why does OS X spend one more packet to establish and close a TCP connection?
Did you ever find this out outside of this site? I looked at this a lot, I even went as far as setting up FreeBSD to see if this was a Unix network stack behaviour (it wasn't) and taking packet captures from a friend's Macbook to see if I could figure it out (I couldn't).

comment Oracle 11g TNSLSNR LAST_ACK connection flooding
No, one side is always the active closer, one side is always the passive closer. The active closer is the one who sends the first FIN. Presumably, the active closer is the end whose application closed its socket first.

comment TCP packet filter based on TCP sequence
Ok, I think you need to take a step backwards and explain the problem you're actually trying to solve. We've gotten a bit ahead of that because you've decided that dropping traffic based on sequence number is the only way to solve it. Your customers aren't paying you to match arbitrary TCP sequence numbers, they are paying you to provide a network service. What about that network service isn't working?

comment Linux Centos6 adapter bonding - Cisco 2960S EtherChannel LACP
In fact you should do this, because starting NM in the graphical interface with nm-applet will let NM manage any interfaces which don't have NM_CONTROLLED=no anyway.

You can also just add NM_CONTROLLED=no to any ifcfg-files for interfaces you don't want managed by NM. I do this on my laptop, so network scripts manage the bridge and wired connection, but I can still use wifi from the graphical interface.
