Re: Lots of incoming traffic on UDP 1026 and UDP 1027?

I initially thought that, too, that it was a DDOS, but the csv log had 
significant gaps of time between instances--a DDOS would have lots coming 
in at the same time, not a few every 10 or 20 minutes. 

Certainly there were a number of illicit connection attempts, but the log 
is for two days and there was only 190 or so connection attempts--I don't 
think it is a DDOS.

Sounds Like a Denial of service attack. Contact your ISP and tell them
that you think you are getting A DDOS attack... Tell them to close
those ports for a day or so.. then you problem should be solved.

I searched the archives at SecurityFocus and couldn't come up with
anything useful other than someone with Zone Alarm obviously saw the
same activity and people were trying to tell him to look for listening
ports on his machine, which is not the case.

I'm getting literally hammered by tons of various IP's on UDP 1026 and 
UDP 1027

I've attached a CSV log, modified a bit, from my NetScreen 5.  I only
showed the last 15 bytes of the Source IP:Port so the first octet,
give or take a few bytes, is cut off.  I left a few columns out as

Let me know, this has been going on for quite a while, and all my
searches are ending in vain.  Any ideas?
