I recently installed dc++ for linux.
The problem is that I can download only when my firewall is disabled.
I am rather new to linux and I don't know how to configure the firewall in order to use dc++ properly.
Please help.


I belive because of this problem azureus doesn't work either.

You need to forward the correct ports through your firewall. I don't know what the defaults are for either but I believe Azureus has a load of info about this on their home page, check it out.

And how do I forward a port. Let's say I am using port 34000.
I've used the Security Level Configuration in the Administration submenu. I've added port 34000 to the trusted sevices.
Still doesn't work.

as root run the command 'iptables -L' and post that here.. which might give us some related info.

are you on a LAN with a router or other hardware firewall device? if so, are they configured properly?

root@144 da_marius]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination

Chain FORWARD (policy ACCEPT)
target prot opt source destination

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

The above shows that the Firewall on your Linux box is disabled - there are no Iptables rules.

However, are you behind a Router or other firewall - eg and ADSL router? If so, you will need to forward ports to your Linux box. This is typically done by accessing the router's config through your web browser, and setting up a virtual server for that port.

I hope this helps

sorry
this is the right one :
[root@144 da_marius]# iptables -L
Chain INPUT (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere

Chain FORWARD (policy ACCEPT)
target prot opt source destination
RH-Firewall-1-INPUT all -- anywhere anywhere

Chain OUTPUT (policy ACCEPT)
target prot opt source destination

Chain RH-Firewall-1-INPUT (2 references)
target prot opt source destination
ACCEPT all -- anywhere anywhere
ACCEPT icmp -- anywhere anywhere icmp any
ACCEPT ipv6-crypt-- anywhere anywhere
ACCEPT ipv6-auth-- anywhere anywhere
ACCEPT udp -- anywhere 224.0.0.251 udp dpt:mdns
ACCEPT udp -- anywhere anywhere udp dpt:ipp
ACCEPT tcp -- anywhere anywhere tcp dpt:ipp
ACCEPT all -- anywhere anywhere state RELATED,ESTABLISHED
REJECT all -- anywhere anywhere reject-with icmp-host-prohibited

You need to set up DC++ properly.
1) Open DC++, and open the settings window. In the "Connection Type", enter the port that you want DC++ to run on. Choose 1412. Go the www.whatismyip.com, and enter that IP address. Click OK.

2) Open your firewall settings. Click Settings - Administration - Security Level and Firewall. You will need to enter your root password when prompted. In the window that is displayed, click "Other Ports", and then click Add. In the small window that comes up, enter 1412 for the port number, and click OK.

3) You have not said if you are behind a router yet. If you are, you will need to set up a "Virtual Server" on that router, forwarding port 1412 to your computer.

I hope this helps
