low ID su aMule

[crema12]

Ciao,
Lo sò che l'avranno chiesto 3 miliatdi di volte ma ancora non c'ho capito nulla... com si fa a non farsi dare più un Low Id? Basta condividere più roba possibile?

[avrobay]

Credo che dipenda dalla " client TCP port " il cui numero puoi settare in Preferences > Connection.
Sei dietro un firewall o un router... spiega meglio.

Sì precisamente, come porta ho la 4662 di default. Sai quale va bene?

Fai questo test:

Che cosa ti dice?

Intanto da aMule.org ti copio e incollo questo:

aMule connects to server, but it is always given Low-ID. Why? and, can I do something about it?
This can bue due to three reasons:
Some necessary port is not opened in your firewall. Read this to get to know what to do and check here if the ports are open.
The server is very busy or maybe badly configured, so it's giving you a Low-ID. There's nothing that can be done in this case other than reconnect or connect to some other server.
Some ISP forbid the use of p2p applications, such as aMule, by not allowing traffic through popular p2p ports. In these cases, configure aMule to use some other port. It would be even better if it was some popular port used for some other issue. It's been known that on some ISPs it worked with port TCP 25600.

What is LowID and HighID?
Each client is assigned an ID (Identification) number which is unique and will distinguish the client from all other clients on the server. If this ID is below 16777216 (16 million) then you have a LowID and anything over is a HighID. Whether your client receives a high or low ID will depend on your client and whether or not the Client TCP port is open. Client TCP Port is an customisable option located in Preferences -> Connection. The default port is 4662 which is fine. If you understand what ED2K is, odds are you'll understand the chances that clients with LowIDs may be unable to connect to other clients with LowIDs which reduces transfer rates significantly. This is the reason why having port 4662 TCP (or the one set in Preferences) is so important. Some of the larger servers refuse clients with LowIDs and disallow connections since LowID clients have data transfered through the server, rather than directly from the other client, which in turn adds more overhead for the server.

For clients with a HighID, their ID is the result of a mathematical operation with their IP which corresponds to A + 256*B + 256*256*C + 256*256*256*D, where the IP is A.B.C.D. Keep in mind that this ID has identification purposes as well. Apart from having an ID over or under 16777216, it does not matter if the ID is bigger or smaller. This means a client with an ID of 50000000 isn't any better than a client with an ID of 49999999. The only exception is at times servers are either incorrectly configured or are very busy and issue LowIDs to clients even though port 4662 TCP is open. These are rare exceptions but it can happen sometimes.

If you're unsure about having proper port settings, you can test your ports here.


Which ports do I have to configure in a firewall or router to run aMule?
aMule works even with no specific ports opened, but you won't get a HighID in this case. As mentioned above, to be given a HighID, port 4662 TCP (or the one set in the Preferences) must be listening (i.e. opened in your firewall and forwarded in your router).

Apart from that port, to have an optimal ED2K experience, two more ports should be enabled as well. First, the UDP port 4672 (which can also be changed to any other number in the Preferences) and secondly, the secondary UDP port which can't be set in the Preferences. This UDP port is your TCP port + 3 (e.g.: TCP=4662 then UDP=4665).


What does each port do?
Well, since most ports can be configured to be set to any other number, the defaults will be listed:


4662 TCP
Client to client transfers.
4665 UDP
Opened on client, used for global server searches and global source queries. This is always Client TCP port + 3.
4672 UDP
Extended eMule protocol, Queue Rating, File Reask Ping
4661 TCP
Opened on server. Allows connection to server.
4665 UDP
Opened on server. Allows asking for sources. It is always Server TCP port + 4.
4711 TCP
WebServer listening port.
4712 TCP
External Connection port. Used to communicate aMule with other applications such as aMule WebServer or aMuleCMD.

Ho fatto il test e mi dice questo:

----------------------------------------------
Error: TCP port 4662 is unavailable. Make sure your firewall or router is allowing/forwarding this TCP service port and your ED2K client is running (i.e. aMule, eMule).
Detailed Error Message
TCP Error 111 Connection refused

Explanation
The port is available for connections but a connection was refused meaning there is nothing listening on that port. This most likely means you can use ED2K but your client is not currently running. Try running this test again with an ED2K client running to make sure you can really establish a connection. No info available; this TCP error probably indicates a problem with the networking on your system (i.e. the TCP/IP stack).

In pratica, l'up load va bene, è il download che va lento se non in alcuni casi che arriva a 15-25 kbps. Confesso che ancora non ci capisco nulla, provato varie porte ma è sempre la stessa cosa (anche quando le metto a caso!).
Mi chiedo se allora la configurazione non deve essere fatta direttamente sulla connessione del modem, è così?

[avrobay]

Hai fatto il test mentre aMule era aperto oppure era chiuso?
Io non ho capito: hai i firewall alzati o hai un router?

[crema12]

Sono anche andato in preferenze di sistema/network e settato le porte nella scheermata firewall ma nulla, mi dice sempre che sono low ID!

[crema12]

L'ho fatto quando aMule era aperto. Se firrewall o router non te lo sò dire. Quello che ho per collegarmi è il router di libero

uhmmm, mi sa che devi settare le ip tables del tuo router che immagino sia un modem/router.

qui lo dice il messaggio di errore del server:

Error: TCP port 4662 is unavailable. Make sure your firewall or router is allowing/forwarding this TCP service

In parole povere, quando dall'esterno arrivano le chiamate alla porta che hai aperto sul mac, il router deve sapere dove mandarle ovvero, a quale dei computer della tua LAN. Anche se ne hai uno solo attaccato, devi tu dire al router cosa fare cioè gli devi dare il numero di IP interno alla tua LAN del computer.

Esempio: il tuo router ha un IP 192.168.1.1 il tuo Mac 192.168.1.2.
Devi istruire il modem/router ad inviare tutte le chiamate TCP alla porta 4662 verso il tuo mac ovvero allo IP 192.168.1.2. E' semplicemento questo il problema.

Tu in che condizioni sei? ci descrivi sommariamente il setup?
