Intermittent Flashing/Recording...

[bathingaper]

I have a strange problem with my Solo2 box. I am currently running Apollo 023 however this issue was happening in an earlier build before I updated.

Basically if I'm watching a programme, the screen will briefly go blank and re-appear. After it did this a few times (sometimes 4 or 5 times a minute) I checked the on screen display of the Solo2 and saw that it was recording and then stopping.

I have no timers set up and no recordings appear on my internal HDD. Can someone please advise what's going on?

More than likely someone has gained access to your box & is streaming from it.
Next time it happens, telnet into the box & issue:

netstat
Should point you towards who's using it.

[bathingaper]

thanks, will try that although i'm not sure how anyone has gained access to it considering I have setup a complex password which I haven't shared with anyone. Will give it a try next time and report back

[judge]

Password might work for WebIF, doesn't mean it will work on streaming ports.
If you open those ports to an outside network, you're asking for anyone to use your tuners.

[judge]

A simple google code search will show loads of boxes running WebIF, password protected or not.
Then trying those boxes using a streaming app on default ports or running a port scanner gives access.
Using a VPN for external access is your best solution.

[Larry-G]

As judge says, if you open ports for streaming then passwords are pretty much useless. Try the net stat command and report back as more likely than not you will have been hacked via those open streaming ports.

Hi there, it's happened again so I did as suggested above and have found the following results:

my transcoding port is 8002. I have since closed that port on my router and deleted the firewall rule for both 8001 and 8002 however doing a netstat after 5 minutes provides the same results as above.

suggestions?

edit:
tcp 0 0 VU_Plus_Solo2.home.gateway:ssh Dell_T3500.home.gateway:49917 ESTABLISHED <--- this is my Pc.

Just rebooted now and I have the following. Looking cleaner now.

will monitor this over the next few days. Thanks for the help guys. For someone that works in IT - I was totally oblivious to this! :D

Quite a few different IP addresses logged on there that shouldn't be...
Serbia, Egypt, Tunisia...

Don't feel too bad, most people dont give it a second thought that their receivers can be vulnerable, at least now you know and can take the appropriate measures.

cheers mate, time to investigate VPN access to my box.

@judge, while I understand the risk of leaving a port (in this case 8002) forwarded across the home router, what I'm not quite following is how the streaming/transcoding is being initiated. I thought the Web-IP port (default 80 but can be changed) was needed in order to trigger the transcoding on 8002 or raw streaming on 8001? I see both those ports 8001 and 8002 being in "listen" mode on netstat - do they actually accept command input and commence streaming? Anywhere I can look for more info? I have certain ports forwarded across my router for Planeplotter and some gaming, but the apps listening on those ports are pretty much unable to do anything except their designed function. The issue as I would see it is that the E2 boxes generally run everything as root and have no password protection by default.

[judge]

Short answer, if someone knows you have streaming ports open, they can construct the URL to stream.
Longer answer in reported post.

Don't understand the "longer answer in reported post" :confused:

If you are not actually streaming from your box, how does the external person actually initiate the stream?

You don't have to be streaming you just need to have the port for streaming open as it's essentially unprotected over those ports.

Do these ports open if you are only using Samba for internal FTP say from my LX3 to my Duo2

No, you would have to open them your self in your router. So if you have not there is nothing to worry about, this mainly affects those users who open ports so they can stream channels to a mobile device while out and about.

I'm struggling to find a definitive post for configuring OpenVPN on my box. Can anyone point me towards the correct/working config method?
