Summary | 0000049: Strange ports ranges utilisation | ||||||||
Description | Hi there, Each time I run aMule (w/ TCP=24662 & UDP=24672) I've got troubles getting sources. So I had a look to my firewall settings and it appears that for each session it uses random ports in, for example, 33000-33200 or 41100-41300 (tcp) ranges. | ||||||||
Additional Information | At first, I thought it what "other people's" firewalls troubles. But it seems that it comes from the program as there are 2 main ranges of tcp ports that are concerned. As I can't stand shuting down my firewall, I have to check used ports to open them for each session. But it's an important security issue to let 200 ports opened... So, is there a mistake in aMule ports management or is that normal and can be handled easily in the firewall ruling method ? | ||||||||

It's a bit hard to tell from your description, but as far as I can see, the 200 ports you are reffering to are the outgoing connections, and you shouldn't have to open your firewall for those. Try executing this command while aMule is running. It'll show you the 3(!) ports you need to open in your firewall: 'netstat -npl | grep amule' Cheers, Xaignar |

Well... first of all : thx for your answer ;) Here is the result : $ netstat -npl | grep amule (Tous les processus ne peuvent être identifiés, les infos sur les processus non possédés ne seront pas affichées, vous devez être root pour les voir toutes.) tcp 0 0 0.0.0.0:4712 0.0.0.0:* LISTEN 9986/amule tcp 0 0 0.0.0.0:24662 0.0.0.0:* LISTEN 9986/amule udp 0 0 0.0.0.0:24665 0.0.0.0:* 9986/amule udp 0 0 0.0.0.0:24672 0.0.0.0:* 9986/amule unix 2 [ ACC ] STREAM LISTENING 188703 9986/amule /home/logon/.aMule/muleconn But : all those ports are opened ! And if I run snort (firewall shuted down) I've got : 05/28-20:01:28.357483 xxx.xxx.xxx.xxx:50287 -> yyy.yyy.yyy.yyy:5662 TCP TTL:64 TOS:0x0 ID:1153 IpLen:20 DgmLen:137 DF ***AP*** Seq: 0x7BF7745E Ack: 0xE759D194 Win: 0x16D0 TcpLen: 32 TCP Options (3) => NOP NOP TS: 45259596 996718 w/ x = my PC & y = other people |

Those are outgoing connections to other *Mules for data transfer. You tcp/udp port are used for incoming, and the kernel is the one deciding which ports to use when we open it with no port number. It's more a wxWidgets issue (we use wxSocket) than our own. |
