sudo iptables -A INPUT -p tcp --dport 6881 -j ACCEPT
this is the port that the built in ubuntu bittorrent client uses.If you are using different port you need to enter instead of 6881.
If you want to lockdown your machine use the following command
sudo iptables -A INPUT -p tcp --dport 6881 -j DROP
Hi,
By default, all ports in ubuntu are open unless firewall has been activated, in my case, all my inbound ports for Ktorrent, aMule etc. work fine, I don’t have firewall activated and use a router.
i had try the command above but the error msg come out
Bad argument `–dport’
Try `iptables -h’ or ‘iptables –help’ for more information.
Kind of a funny coincidence but while I was looking over these commands I noticed that all errors result from [OPTIONS] which require a double-hyphen. When viewed on here they render as a dash or a long single line while the need to be two separate hyphens.
Make sure you check for this when copying commands to avoid errors. Took me awhile to figure it out
Hullo,
I did what the instructions said and it only limited my down/up speed. But as soon as I dropped the port my down/up increased.
