XP SP2 TCP Connection Limiter.

pornst4r · 22 Οκτωβρίου 2005

XP SP2 will limit your max connections per sec.

From Warp2search:

Just found this in my event-log after starting emule:

"EventID 4226

TCP/IP has reached the security limit imposed on the number of concurrent TCP connect attempts"

This is what I get from a M$-Guy when i asked him why XPSP2 slows down programs like emule which open many connections to different destinations:

"Thanks very much for responding. This new feature is one of the stack's

"springboards", security features designed to proactively reduce the

future threat from attacks like blaster and Sasser that typically spread

by opening connections to random addresses. In fact, if this feature had

already been deployed, Sasser would have taken much longer to spread.

It's not likely to help stop the spread of spam unless spammers are

trying to reach open email relays in the same way, by opening

connections on smtp ports of random IP addresses.

This is new with XP SP2 and we're trying to get it right so that it does

not interfere with normal system operation or performance of normal,

legitimate applications, but does slow the spread of viral code. New

connection attempts over the limit for half-open connections get queued

and worked off at a certain (limited rate)."

If anyone knows how to switch it off please leave a comment...
