Hi there
i m new to IPTV so u just bought a Mag254 box from someone and paid for 1 month subscription so that I can take a look at the settings for subscription so how do I find out that who my service is with so that I don't have to pay big bucks to that guy.And than I can buy the subscription directly from the provider !
where should I get the subscription or donation from ?
which site is realiable?
thanks in advance :)
 
Hello everybody! I have got a test Stalker Middleware on Ubuntu 14.04 in VirtualBox. I added a user and a test TV channel to it, but Mag 254 could not connect to it.
So Stalker at the moment running in a virtualization environment for test purpose. I added the Ubuntu Server private address to Mag portal URL but this is not worked.
What could be the wrong ?
