Problems with ports and amule

[ejgutierrez]

Hello, i need desperatly your help.

Im using fedora core 4 with all updates.
aMule 2.1.3 using wxGTK2 v2.6.3 (Unicoded) and kernel 2.6.17-1.2142_FC4 i686
I want to open some ports for amule, bittorrent, etc... ( 4662, 4665, 4772, 6881 etc ...)
I have one pc conected to a router.
My private ip is 192.168.1.3 and the router 192.168.1.1
In windows i have high id and it works all fine ( so i have the ports open in my router).
I have read tons and tons about opening ports and something dont rule.
I use firestarter and iptables.
When i do a a scaner test in the web browser, they say that ports are closed.

netstat -lnptu

Any ideas, help ? Please, please
amule bug, fedora bug? seems to be something related with firewall and ports.
Thanks in advance

Did you open the ports in the linux software firewall? It's in system/administration/firewall and security settings menu.

[ejgutierrez]

yes i hope so.

Proto Recv-Q Send-Q Local Address Foreign Address State PID/Program name
tcp 0 0 0.0.0.0:4662 0.0.0.0:* LISTEN 7473/amule
udp 0 0 0.0.0.0:4672 0.0.0.0:* 7473/amule
seems like port 4662 is active and listening

any ideas please ?

I use amule and don't have problems other than trying to use that piece of junk built in firewall config gui that fedora has. It's buggy at best and doesn't alway seem to open the ports that I specify. I'll add a port to open and exit and restart the firewall and then go back into the gui and it doesn't have the port listed that I just added. And sometimes when I add more than one the one I added previously disappears.

Anyways keep in mind that you will need to open the port for connecting to the network that each particular server uses. That's specified under the network connections. You will also need to open the ports that you have specified in the preferences. You have the default port and then the extended ports.

I suppose i have to use something like this ( taken from amule wiki):

"If you have a default Fedora Core firewall setup and a default aMule rpm installation then you should do as follows:

1- Insert iptables rules:

/sbin/iptables -I RH-Firewall-1-INPUT -p tcp --dport 4662 -j ACCEPT
/sbin/iptables -I RH-Firewall-1-INPUT -p udp --dport 4665 -j ACCEPT
/sbin/iptables -I RH-Firewall-1-INPUT -p udp --dport 4672 -j ACCEPT

2- Get the rules saved (in order to get the rules after restarting):

/sbin/service iptables save "

But when i execute /sbin/iptables -I RH-Firewall-1-INPUT -p tcp --dport 4662 -j ACCEPT
it says: iptables: No chain/target/match by that name.
Referring probably to RH-Firewall-1-INPUT. I think that the problem begins here. As i said before i have the ports correctly open in the router ( windows 98 emule runs perfectly). I have the ports open in my pc ( as you can see in a previous post in netstat -lnptu.

My /etc/sysconfig/iptables file:
"
# Generated by iptables-save v1.3.0 on Sun Sep 24 20:11:56 2006
*filter
:FORWARD ACCEPT [0:0]
:INPUT ACCEPT [22175:19800302]
:OUTPUT ACCEPT [18275:1326515]
-A INPUT -p udp -m udp --dport 6881 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 6881:6999 -j ACCEPT
-A INPUT -p udp -m udp --dport 4661:4675 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 4661:4675 -j ACCEPT
-A INPUT -p tcp -m tcp --dport 6881:6889 -j ACCEPT
COMMIT
# Completed on Sun Sep 24 20:11:56 2006"

Hope with this information anyone can help me what is missing, maybe a firewall bug?
Its very important to solve this problems because i cant use azureus, mldonkey, xmule nor amule.

Thanks in advance

Hmm, I've only had problems with ports still appearing closed if I opened the port while the program trying to access that port was running. I suspect that is more of a problem with an environmental variable being read instead of rechecked.
