[Dxspider-support] F1HMR, IP address 88.178.71.87

[Martin Davies G0HDB]

Patrice:

Late in the evening of Saturday 22nd April I became aware that there were multiple repeated 
connection attempts from a station with your callsign of F1HMR at IP address 88.178.71.87 
to my GB7DXC-5 DXCluster node.

The sysop console on the node showed that there was a connection attempt every 2 
seconds, and that each connection attempt was rejected by GB7DXC-5 because you were 
already logged in to three other DXCluster nodes (DB0SUE-7, F6GCP-3 and PA4JJ-2).

Because of this abuse of the DXCluster I have now explicitly locked you out of the 
GB7DXC-5 node, so you will never be able to connect to it, and I have added the IP address 
shown for your connection attempts to the list of 'bad' IP addresses that is propagated across 
the worldwide DXCluster network.

Although there seemed to be a cessation of the connection attempts for a while on Sunday 
23rd April, this morning I can see on the sysop console for the GB7DXC-5 node that your 
station still appears to be making repeated multiple attempts to connect to the node, with the 
frequency of the connection attempts now being up to ten per second.  Each and every 
connection attempt is being rejected because you are locked out of the node and your IP 
address is blocked but nevertheless your behaviour constitutes very serious misuse of the 
DXCluster and my GB7DXC-5 node in particular.  The ongoing repeated multiple connection 
attempts in effect constitute a Denial of Service (DoS) attack on my GB7DXC-5 node and if 
they continue I will not hesitate to report you to the relevant Internet authorities in France and 
elsewhere if necessary.

Please ensure that you configure your station so that it no longer makes these repeated 
multiple connection attempts to the GB7DXC-5 DXCluster node.

If you are confident that the attempts to connect to the GB7DXC-5 node are not coming from 
your station then I would suggest that you have an issue with your callsign being pirated by 
whoever owns the IP address 88.178.71.87 and that you will need to investigate this with your 
Internet service provider and perhaps also the French authorities responsible for amateur 
licensing.
