security issue.

[Marwan Sultan]

Hello Tech.

  For the past few days, i had troubles connecting to my KIFCO server
  Kifco.net
  And at night around ( 23:30 GMT ) and the following hours i cannot
  connect at all, it connect for 1 second then everything lags,
  I can see slow connections and lagged ones.

  After all when im able to connect to the machine, I checked the dmesg log
  I found the follow :
  
Limiting closed port RST response from 268 to 200 packets per second
Limiting closed port RST response from 302 to 200 packets per second
Limiting closed port RST response from 296 to 200 packets per second
Limiting closed port RST response from 213 to 200 packets per second
Limiting closed port RST response from 272 to 200 packets per second

 Which consider a PORTSCAN and an ATTACK.

 Also as I know from my friend on IRC DALnet network that dragons.dal.net
 is hosted in maxim, and just in this second its disconnected.
 Maybe because of an IRC server you have this attack?
 I had two IRC servers on DALnet in Past, and im familier with this trouble.
 anyhow, IRC is not my part of concern or who owns it.
 Kifco is my concern.
 Can you disable all PINGS from router to my server?
 Please can you update me and check this issue?

 Your updating for me, is really appreciate it

 Thank you.
