Title: amule sends ICMP requests even it is off
Post by: noname2007 on December 06, 2007, 03:13:38 AM

Hi all,
I am very confused why amule sends ICMP request when it is "off"(means I have not started amule), is it a feature or I misconfigure something?

Here is an example of the request, I use x to denote the ip :
=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+

12/05-18:08:00.204922 61.173.x.x:24429 -> 192.168.0.101:4672
UDP TTL:115 TOS:0x28 ID:37484 IpLen:20 DgmLen:63
Len: 35
=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+=+

12/05-18:08:00.204974 192.168.0.101 -> 61.173.x.x
ICMP TTL:64 TOS:0xC8 ID:60873 IpLen:20 DgmLen:91
Type:3  Code:3  DESTINATION UNREACHABLE: PORT UNREACHABLE
** ORIGINAL DATAGRAM DUMP:
61.173.93.193:24429 -> 192.168.0.101:4672
UDP TTL:115 TOS:0x28 ID:37484 IpLen:20 DgmLen:63
Len: 35
** END OF DUMP

Any idea?
Thanks

aMule (or any other userspace) program can not send ICMP packets. What you see here, is your computer replies to someone   else. That "someone else" trying to connect to aMule port, but since aMule isn't running, port is unreachable. That's why ICMP is sent. RTFM next time.
