I need some advice.
I repeatedly receive two subsequent ICMP packages from one host.
One is a large ECHO packet, the other one is an ICMP source
The frequency is not quite high enough to consider this a
DoS-attack... even my 128kbps-line can deal with these two every
few hours... ;o))
[**] IDS246 - MISC - Large ICMP Packet [**]
09/09-07:01:52.042189 18.104.22.168 -> xx.xxx.x.xxx
ICMP TTL:241 TOS:0x0 ID:41985 DF
ID:48282 Seq:61662 ECHO
[**] ICMP Source Quench [**]
09/09-07:01:52.216006 22.214.171.124 -> xx.xxx.x.xxx
ICMP TTL:241 TOS:0x0 ID:41987 DF
Still, I ask myself what this may be. The IP obviously belongs to
a webserver from the Brandenburg government. An email remained
unreplied so far.
Any clues as to what this might be? Is someone trying to DoS them
and spoofing our address...??
