After all, they just don't answer and they won't tell you why (AFAIK there is no way to ask them why either)... You could try to check for patterns in the incoming IP addresses to see from how many different places these connections are being made. I think that way it should be possible to figure out from which geographic location these problematic connections are coming from as well. What you would do with these findings I am not sure though. If these connection negatively impact the performance of your servers you should definitely look into to countermeasures mentioned in the RFC here. http://tools.ietf.org/html/rfc4987 _______________________________________________ Kernelnewbies mailing list Kernelnewbies@xxxxxxxxxxxxxxxxx http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
