That workaround is weird, because the two things disabling ED2K-update_server_list_server do are:

  • discarding servers list received from servers (contrary to adding "nolistsrvs" at the end of your client name, the list should still be sent).

The code do to that is short, and I doubt it does anything harmful, like raising an exception:

(donkeyServers.ml:)
if !!update_server_list_server then begin
if !verbose_msg_servers then lprintf_nl () "Received serverlist from server";
let module Q = M.ServerList in
List.iter (fun s ->
safe_add_server s.Q.ip s.Q.port
) l
end

  • discarding Udp packets received, supposedly from a server, but that's not already in the servers list. A Not_found exception is raised in DonkeyUdp.udp_client_handler. I doubt this influences connecting to servers.

Workaround of setting ED2K-update_server_list_server to false works for me too.

Setting ED2K-update_server_list_server to false solved my problem.
So I propose changing the default of true or disable this until it is fixed.

With verbosity ms i can see mldonkey connect and getting the serverlist of the server.But I don't see any connected server(or only the first ones it did connect).
My version is the cvs of 31/03/2006.

After upgrade to 2.4.7 I get a lot of LowIDs with ed2k servers. This is NOT a firewall problem, older version worked with the same settings.

When I connect to server, tcpdump shows that mldonkey does not reply to server's callback as outlined in http://mldonkey.sourceforge.net/LowID. Instead, it merely acknowledges received packets with zero-length TCP payload. This is a proof that connection exists but mldonkey does not write any data to it.

The test at http://tdn.no-ip.org/connection_test gives me "timeout : could not read packet header". If I restart mldonkey and run the test again, it gives "sucess.. your ID should be...". After a minute or so (or if I try to connect some servers manually) - timeout again.

Another test (http://www.preinheimer.com/cgi-bin/connectiontest/connectiontest.cgi), works OK all the time, obviously because it relies only on connection establishment.

I think that this issue has already been reported here: http://mldonkey.sourceforge.net/phpBB2/viewtopic.php?t=4132

My link is not saturated, neither am I running out of file descriptors, neither is MLdonkey busy hashing files.
