The irritating "kad: firewalled"

The irritating "kad: firewalled"

Dear All

The rules of my firewall are

ACCEPT  net     $FW     tcp     4662
ACCEPT  net     $FW     udp     4672,4665

Furthermore, I the port 4662/TCP, 4672/UDF and 4665/UDF are forwarded. However, Kademlia is always "firewalled". Any ideas about this very irritating problem?

Thanks in advance,

Paul

May be ISP port filtering? Just an idea.
Did you test your ports? http://www.amule.org/testport.php

Thanks. eMule on MS Windows and on the same computer connects
without problems to Kademlia network, and I have left aMule running an
entire night and it did not stop saying "kad firewalled". I suspect
that the problem is aMule specific, as there is no progress even when
I stop my firewall on Linux.

I installed aMule 2.1.0 Kad-only on my mother's computer running Windows XP, and I got the "firewalled" notice for 30-45 seconds or so.

In your case, I would advise that you check which ports are opened by aMule on the system, by typing:
netstat -lnptu | grep '/amule *$'

Hope this helps,

also maybe update your nodes.dat and reconnect to kad after that...

kad works fine, i doubt is a problem in mule itself.

is ed2k highID aswell?

do windows and linux have the same IP address?

Here it is, I think!

You said you authorised UDP port 4672, but it's UDP port 4662 which is open.

I do not think so, as I do not see any progress after stopping my firewall. Addicional information regarding the ports forwared on my router:

External port   Interface       Virtual IP      Protocol        Port
4662            PPPoE           192.168.1.2     TCP             4662
4665            PPPoE           192.168.1.2     UDP             4665
4672            PPPoE           192.168.1.2     UDP             4672

4672 PPPoE 192.168.1.2 UDP 4672

^^ tahts the error!

look your output of netstat you have

4662 tcp, 4662 UDP
and 4665 udp

so you changed the default config in your prefs, this way you also have to cahnge the default values in your router settings, or go back to the default in amule

No, I did not change my default aMule configuration.

Should I have the following on my router?

External port Interface Virtual IP Protocol Port
4662 PPPoE 192.168.1.2 TCP 4662
4665 PPPoE 192.168.1.2 UDP 4665
4662 PPPoE 192.168.1.2 UDP 4662

When I tried to add

4662 PPPoE 192.168.1.2 UDP 4662

the router did not allow me, telling me that I was repeating a rule.

I replaced

4662 PPPoE 192.168.1.2 TCP 4662

with

4662 PPPoE 192.168.1.2 UDP 4662

but still no progress.

Thanks, Olivier.

udp 0 0 0.0.0.0:4665 0.0.0.0:* 5336/amule


look at teh both UDP ports on ei s4662 and one is 4665

that is NOT default!! the first udp port should be 4672!!!
check your preferences in amule!

btw if you changed the tcp rule , you should also be firewalled now in ed2k!

you need to forward 3 ports for amule 1tcp and 2udp ports. maybe recheck what you are doing here.

Hi Guys,

it looks there is some room for confusion here.  I do have a similar problem in amule 2.1.0, not with 2.0.3.  Kad is firewalled:

linux /root# netstat -lnptu | grep '/amule *$'
tcp        0      0 0.0.0.0:4662            0.0.0.0:*               LISTEN      30974/amule        
udp        0      0 0.0.0.0:4665            0.0.0.0:*                           30974/amule        
udp        0      0 0.0.0.0:4672            0.0.0.0:*                           30974/amule        

The port forwarding scheme on my modem:

1   10.1.1.4   TCP   4662   4662   
2   10.1.1.4   UDP   4672   4672   

4   10.1.1.4   UDP   4665   4665   
5   10.1.1.4   TCP   4661   4661

I did test the TCP port following the link post before on this thread and it returns OK.  However, that script doesn't test the UDP port.  

Hmmm, I see on the Kad Info tab in the "networks" section:

Kademlia Status: Not Running

which is weird, when I started the little arrow on the top right side of the world icon on the bottom right side of amule's screen was yellow, now it turned to red.  

Oh, well so my new problem is worse.  Before I was firewalled (KAD-firewalled I mean).  Now I am simply not connecting...

This is the log I get when I start:

(in one of these lines I see: 2006-03-04 20:14:39: Read 0 Kad contacts, that sounds bad, but I don't understand the meaning.  Do I need another server?)

Thanks. Now, I have everything right, i.e., the ports selected on aMule's configuration agree with the ports that I have forwarded on the router. However, the reported problem maintains. I now speculate that the cause may be the fact that I am filtering some IPs with ipfilter.dat.

@ankanaan

a lot of ed2k server are down, update your server.met with the help google and retry.

like I said already in your other thread you are connected to a fake server there, so thats why you dont get any sources.

@paulus

well remove it from the .aMule dir and retry, pretty simple to find out...
but kad takes a while to turn from firewalled -> to ok (sometimes 10-20min)

Bingo! By removing ipfilter.dat from .aMule directory, I get "Kad: ok". Should it be the expected behaviour of aMule? I think not, as it is misleading in the sense that it makes us thinking of a bad configuration of the router/firewall.
