Release: 2.00

Platform Version: Linux i386-i686
Binaries Origin: Compiled From CVS
Summary: Connections to itself
Original Submission: When the core is looking for Server donkey-connections,
it uses sometimes also itself as target and connects succesfully (?) to
127.0.0.1, even 127.0.0.2 or the 192.168.0 ip of my eth0.
As my system is running snort it catched yesterday
% attacks method
===============================================
51.05 1478 BAD TRAFFIC same SRC/DST
1478 192.168.0.102 -> 192.168.0.102
one in more Detail:
21:36:37.056961 192.168.0.102.42239 > 192.168.0.102.4662: S 1152749383:115274938
3(0) win 5840 <mss 1460,sackOK,timestamp 360802 0,nop,wscale 0> (DF) [tos 0x8]
Looks like a bug in some of the Network Code.
Any hint?
mldonkey cvs from 2002-11-09 on i386 debian unstable, nearly not all unstable

I see this behavior too (release-2-5-devel branch from yesterday), but I don't
have the server activated. It also doesn't lists a private address, it lists
the official address assigned to me by my provider (the adddress the client
binds the donkey_port (4661 in my case) to).
I think mldonkey should look at the address and don't use it if it's the same
address:port pair it uses.

I saw the same behavior with the mld 2.01. I assume some malicious peer(s)
injecting private IP addresses as servers and mld falls for it and connects to
itself.
If you don't need the mld server just switch it off. You can do this by:
stopping mld, disabling mldonkey server in download.ini ("enable_server =
false") and re-starting mld again. When you have done this, the private IP
addresses
still appear in the server list but mld can't connect to them.
Additionally you could black list the private IP addresses, so these private IP
addresses also do not appear in the server list anymore.
