There seems to be no ill effect and i think the aditional logging that was enabled is why i am seeing this. One intresting thing is that land that is set for sale seems to add in the $ icon on the world map as this is going on. I have never seen that actualy work out side of SA mode. tnx

It has a bad habbit of thinking a real users is gone when there not. they simply tped to anohter insatnce on the lan. Web clents also trigger this adding to 40-50 pings per instance per region x how many users. It buulds to the point of DOS and systems freek out. Also found that changing region.ini region external from FQDN to lan ip (use to work fine) now fails to all but local host. Search loves it though as lan ip as it can update ok if reg with lan ip. (prob not related) All this is falling on the heals of cahnges made at the same time so it hard to sort this out. Unless you run sever insatance (cross lan) as a cluster that forms a grid you may well not see it. On revert to 3 weeks ago, non of this is an issue under the same test conditions. tnx

I have not had any issues other than a chatty console and the trigger conditions are the same: StartPingCheck begins after successful TP within my grid, but not after 'physical' region crossing. (Same system environment as above except 64-bit)

(0017654) samiam (reporter) 2010-12-20 16:35	As the port# it claims are not region or system port numbers (assuming proxy magic of the client). I thought to also try stable imprudence too. Hippo and it make no differnce as to the messages. The port# seems random each time. Im not shure how to test to see if a normal ping is actauly getting thru or not.

(0017721) samiam (reporter) 2011-01-01 20:51 edited on: 2011-01-01 21:01	Tryed latest but this still happens. It is actauly trying to ping as net mon shows. This clogs up LAN with useless net pings. I assume its looking for child agents and on a 36 region megaregion this becomes excessive. At one point the security system taged it as a hack attempt and closed the door on it. It percived this a DOS attack. If the the ping is not needed it shouldent be doing it at all. TNX

(0017722) samiam (reporter) 2011-01-01 21:09 edited on: 2011-01-01 21:18	SubNote: we use ISEC and SANS standared secutity and mon. code reporting tools. just for ref and is flagged as a a weak ping dos attack. ill provied white papers on this if you wish.

(0017723) samiam (reporter) 2011-01-01 21:27	Best advice from SANS handler is to use lan pings that allways ACK, under no cercumstance should ping flood happen. This will be tagged and blocked via gen tools. ie black listed. This needs fixed fast or it will get pasted SANS and tagged!

Mels fixes worked :) If there are NO objectsions ill set this to resolved. Anything after would be a different mantis. Also web clients report mutch smoother responce. Big thanx to all :)

(0017762) samiam (reporter) 2011-01-05 00:17 edited on: 2011-01-05 00:35	I would recomend (TESTERS) updating to current just to avoid some of the chunky bits b4 this :)

(0017799) samiam (reporter) 2011-01-07 17:42	No longer seeing this now Than you :)
