Help! Channel keeps suddenly changing to random station!

[ninjakettle]

I have an issue where every now and then - the receiver will change channel. It seems to be a random channel each time often in a different bouqet.
I have reflashed the image and tried the newest images too - same problem.

From a fresh install, with no plugins, no skins etc - it happens.
I enabled Debugging and cleared the log after a reboot to see what happens.
I get an output (below) but don't see anything that might be causing this. Could it be a hardware issue?

I'm currently running OpenVIX 153, Apollo.

When it happens again try using the netstat command in a telnet session and post the results here.

Your ports are open on your router and forwarded to your receiver. Anyone can access your receiver.

That's true, I wanted to set this up while at work, and didn't change root or setup http authentication. But really, could that be it....someone changing my channels! Forgive my ignorance but is my ip showing somehow up on this forum?

Having a bad evening, laptop died, can't telnet. Tried with Android telnet app..can't bleedin copy paste output...pfft

On any forum, admin/mods can check your IP in the user panel that VBulletin uses.

Some sites record your IP.

True - i guess it could have been any site. Jaysus you'd think people would have better things to be doing.
Right, well if that's the case - it's easy to confirm. I'll update (shamefacedly) later. thanks folks

You don't need your IP to show on the forum, there's a few simple google searches that will easily find open E2 boxes & that's likey what's happened you.

[judge]

Jaysus you'd think people would have better things to be doing.

Chances are they aren't changing the channel for fun, they're either using it to view channels or sell them on on pay servers.
It really is a silly idea to open ports like this.

sure. they were forwarded for just a day or two to allow me to set it up remotely, with only the box itself exposed so I wasn't concerned, but there you go, i guess i shouldn't be surprised scripts and exploit searches exist for that scenario.

So far ....no further random changes. Case closed

If you know the ip you'll need to connect to your box from, it's a good idea to configure your router to forward requests to your box only from that ip. And only for the time slot you will use yourself.

AND enable http authentication and HTTPS authentication in the OpenWebif settings, anyway.
AND set some password for the root account.

Also, it is a good idea to create a non-root user account and disable access for user root in OpenWebif settings.

There are a lot of people out there scanning specifically for Enigma2 boxes with open ports either to steal your details for resale or just to hijack your channels for their own use. Even if you only open ports for a few hrs you are vulnerable unless you route it all through a VPN. Thats just the sad fact of things these days as most users tend to be novices who just want to be able to watch the footy at work from their box at home and Enigma / Enigma2 was never designed with security in mind.

[ninjakettle]

Yep, I closed it all down. I did see the option in openWeb to disable root access - but is there a plugin to manage User's on the box so i can create a standard User? - or is it all Linux commands?
I can go do some homework - just wondering if someone has already made this easier via a plugin.

You don't need so many Linux commands for that.
First, telnet in as root when there are no other users yet defined.

Then, change the password for root:
passwd

Create new account, here "newuser" used as an example for login:
useradd newuser

And finally, set the password for "newuser":
passwd newuser

(When you are logged in as root, you can change password for other user accounts by giving the login as parameter for the passwd command. Without parameters, passwd will change the password for the user you are logged in as.)

It still won't help though, even with passwords set once a port is opened the receiver is vulnerable.

True, but at least the attacker must first guess a working login and the right password before being able to do anything. (Not that it necessarily prevents all attackers, but at least they need some more effort, and that may keep some of them away.)

If, in addition to disabling root login and requiring password for another user acccount, the router passes traffic to the receiver only from certain known ip address(es) only at certain given times, I think it should be safe enough for most of us.

But anyway, I'd like to have an option to prevent any setting changes via OpenWebif, allowing only streaming and adding timers. And it would be really nice to be able to have one account with these restrictions and another one that can do anything you can do. now.
