NI 2100 controller locks

Hi,

I have a problem with 7 NI 2100 controllers. They work well during approx 2 weeks than they are not controlling the atached devices anymore. It is very strange because I'm able to diagnose that commands are sent and received via Netlinx studio and the led light are flashing properly.

When I recompile my program and send it back, everything works fine again for approx 2 weeks.

There are few devices in this installation. Two samsung led displays controlled in RS 232 and one Cisco C20 codec controlled via IP.

Amx firmware version :


C20 Softwear version : TC 5.1.4.295090

Thanks for your support,

    Some things to try...

    First try telnetting into he processor. Once in type MSG ON ALL.

    See if there are any runtime errors.

    Also type GET BUFFERS and see if you have any overruns.

    Report back on your findings.

    Here is the program of AMX :

    What is your opinion ?
    and about the IP_CLIENT_OPEN line...?

    Well ou don't need the ZIP CKIENT OPEN in the Data Event. That's just going to grow a runtime error. Did you as I suggested above?
  • HedbergHedberg Posts: 671
    We've been fighting similar issues with seven NI2100 masters each with an NXV-300 attached. Support has been involved and we've been trying all the typical stuff like turning off udp and zeroconifg. Turning off the Bonjour on the virtual touch panels, setting the ethernet mode and the like. The last thing that support suggested was to turn off the ssh server (set the port to 0) and we haven't had either a master or NXV-300 drop off line since. But, the customer's IT guys have been mucking about doing all their super secret crap so who knows what's made the problem go away.

    Anyway, you might try the ssh port thing as it's very unlikely that you are doing anything with it.

    Boy oh boy, this why you don't text and drive. You can't type for crap.

    We too have seen systems lock up after 3 to 8 days, we did hardware and network swapouts trying to isolate it. The NetLinx would literally stop, the heartbeat light would be on solid, no communication, and a hard reboot was required to recover.

    Then log review showing intense outside hacking attempts on telnet. With IPs from China, Russia, and elsewhere, we saw as many as 200 login attempts an hour, sometimes for hours. It looks like it used up all the IP resources of the Netlinx, locking us out.

    We set the router to refuse all outside connections except for a few specific domains, and it appears to have stopped both the attacks and the lockups.

    I didn't mention this earlier as this thread OP implies that the NetLinx was still communicating without a reboot, a circumstance we didn't see... so this may have nothing to do with this issue, but it clearly can be a problem when the NetLinx is exposed for remote access.

    A Virtual Private Network setup is another solution on this issue. We opted to try the IP range blocking first as it was simpler.

    I had a 3100 locking up inexplicably as well, and the problem resolved itself without me ever finding the cause of it. I came to the conclusion it was IP related, which John's response may shed some light on. I have to wonder if there is a Botnet out there latching on to AMX controllers thinking they are PCs it can suborn.
  • John NagyJohn Nagy Posts: 1,734
    There are more bots every day, combing random IP addresses and ports looking for responses from exposed machines. Once they find a port that replies, the info is passed to another network of bots that concentrate on hammering the ports with brute-force random sign-on efforts looking to get inside. Until they get past the login, there's no way to be sure just what kind of machine or content they've found, so I am pretty certain that AMX boxes specifically aren't "targeted"... just found.

    While any IP is at risk of being targeted, we have watched enough systems in widely placed areas to see that IP ranges in high income areas are much more targeted than others. Nantucket Island, San Francisco City, and Manhattan areas are much more highly attacked than others. Which makes sense if your purpose is identity theft. Follow the money.

    In this environment, a shocking number of (our and other) dealers routinely leave the Netlinx and panel VNC connections exposed, open and completely unsecured... for their "convenience".

    Don't.

    Had the same problem with an IP address from China - was bombarding SSH and locked up the master. It's been happy ever since I shut down the telnet & SSH port forwarding.
