Can Linux DVR on network invite virus to crash pc?

Recommended Posts

Greetings:

I installed a few weeks ago an Intellicam standalone DVR in a restaurant. THe DVR is on the network and 3 router ports are forwarded to it, all set to both TCP and UDP.

 

1 PC on their network has DVR client software installed (non-IE browser based).

 

Remote access is via IE browser.

 

Customer claims that the PC caught a virus and now has 'streaming porn' and that all his payroll data has been 'wiped out' (payroll application is on that PC. PC is networked to other PC's in building). He yanked the network connection out of DVR and is blaming the DVR.

 

I am not a PC network expert or a PC systems guru.

 

But i know that some of you guys are.

 

Is this a feasible scenario? Could placing the DVR online have somehow invited this disaster?

 

Has anyone experienced something similar?

 

Any info is greatly appreciated.

 

Thanks

 

Jeff

the problem is you have port 80 set at both tcp and udp. should give your dvr a port away from 80.

as far as the porn this will be down to him or his staff and the cookies restarting because of your tcp udp set for all traffic

Tom-

 

Thx 4 reply.

 

AFAIK, port 80 was left alone.

 

I had to solicit the router management company to forward the ports in the Cisco router.

 

Since there had been an old Rapid Eye DVR there, which used ports in the 10000 range, I requested and got 3 10000 range ports all configgedfor TCP & UDP, since the DVR required I believe at least 1 port to be UDP and the others TCP.

 

The router management tech said having all 3 ports configged for both UDP and TCP would not present a prob.

 

Again, I am not a network or systems guru and so, at this moment am not aware of potential dangers imposed by this type of setup.

 

AFAIK, port 80 is still set to TCP.

 

AFAIK, the only ports configured also for UDP are the 3 10000 range ports I requested ported to the DVR. Could these be affecting the rest of the network?

 

Can you please expound on: "as far as the porn this will be down to him or his staff and the cookies restarting because of your tcp udp set for all traffic"? Can you describe the process that would occur if the client or staff accessed a porn site and cookies were automatically downloaded? would they then possibly initiate connection to porn URL's automatically?

 

Thx for info.

LOL. No ... they either installed some free software on their computer or they were visiting porn or casino sites. Sounds like a browser hijacker, using IE.
