comment ptp time synchronization on centos6/rhel
PTP is different from NTP. But unless the OP has a specific requirement, he should use NTP instead. It's not quite as accurate as far as getting machines on a LAN to agree, but it's much more accurate to real wall clock time.

comment Web server response degrades even though it doesn't seem busy
Disk I/O, network I/O, and memory would be the next things to look at after CPU.

comment How would Microsoft know that my MS SQL Server is Genuine and properly licensed?
Plus, producing a license file doesn't prove you have the right to use that license.

comment Why bittorent needs many ports
I don't think he's asking about the port the server is listening on. I think he's asking about the ports used by the connections.

comment Cisco 877 responds to IPv6 ping from internet, doesn't respond to internal clients
Is the address the clients cannot ping 2001:111:1111::1? (That is, the address assigned to the VLAN they are in)

comment Two network adapters with the same ip
That would allow him to pick one machine for each IP, but he couldn't access two different machines with the same IP. He needs DNAT for that.

comment max number virtual IP addresses per NIC
I've done over 2,000 before without a problem. I've read success reports up to 5,080 addresses. (And that was all that person needed.)

comment Two network adapters with the same ip
Yes. So that means that 192.168.0.50 could mean two different machines. He wants to be able to access both of them, one as 1.2.3.50 and the other as 4.3.2.50 -- that's why he's using DNAT.

comment Two network adapters with the same ip
That was just an example. I picked 50 arbitrarily to try to explain what I mean. He has two networks that both use the same IP address range, and he wants to remap those addresses into distinct IP ranges as seen from his machine. That's why he's using NAT.
