Peculiar effect with keyboard -solved (David Bowskill) ---------------------------------------------------------------------- Message: 1 Date: Wed, 14 Jul 2010 22:35:33 +1000 From: Basil Chupin <blchu...@iinet.net.au> Subject: HOW TO: Netcomm NB9WMAXX and Firewall To: Ubuntu forum <ubuntu-au@lists.ubuntu.com> Message-ID: <4c3daf15.7010...@iinet.net.au> Content-Type: text/plain; charset="iso-8859-1" In the very early hours of this morning (Wednesday) we had here in Canberra one hell of a wind 'storm' with the result that one of our neighbour' trees was bought down and short-circuited 2 phases of the power lines. The power surge took out my modem's power unit. Today, as replacement, I bought the Netcomm NB9WMAXX (ADSL2+VoIP) modem/router and now have it working for both ADSL and VoIP. However, for the first time in ~7 years I now FAIL the ShieldsUp!, TruStealth, test on grc.com: all ports are in Stealth mode but the FAILure occurs because the Netcomm accepts and replies to ICMP pings. This didn't occur on the Netgear and the Zyxel modems I had before. The question now is: does anyone know which parameter in this Netcomm I need to play with - and what are the settings - to stop these responses to pings, please? As additional info, I am running Ubuntu Lucid (is there something in Lucid which could be set? - although I have never had to fiddle with any settings in Ubuntu before so I believe that this is modem firewall hassle, but then I am not a network geek :-) ). Any advise would be greatly appreciated. BC -- And God created Woman; and to repent He then created Beer. -------------- next part -------------- An HTML attachment was scrubbed...

I'm not familiar with that router firmware but there should be an option in the firewall settings to block ICMP requests. I'm pretty sure my last Netcomm ADSL/Router had that option. > As additional info, I am running Ubuntu Lucid (is there something in Lucid which could be set? - although I have never had to fiddle with any settings in Ubuntu before so I believe that this is modem firewall hassle, but then I am not a network geek :-) ). You could block ICMP via UFW but, that will not stop your router responding to the requests, only the Lucid system. And unless you're running a DMZ directly to said box for some reason, that won't achieve what you want. As a side note, you may want to see if there is a firmware update available.

As far as i can tell from the documentation at http://www.netcomm.com.au/netcomm-products/voip/nb9wmaxx, there is no way to disable pings for the WAN interface. My advice: ignore grc.com. :-) Paul -------------- next part -------------- An HTML attachment was scrubbed...

I work for an ISP (Adam in Adelaide) and get this question a lot from customers, and also talk to a lot of customers that have gone and blocked pings. Here's a couple of items for consideration : - people generally want to block pings to be protected against ping "floods" - blocking pings only stops your router from replying to pings, it doesn't stop someone sending you pings. so a ping flood can still happen. - these days, if someone wants to discover you on the Internet, they're probably going to port-scan you, not ping you. Once they port scan you, maybe they'll find a (web, mail, ssh etc) server. Then they'll try to exploit that server. If you're not running any servers, no problem. If you are running servers, then blocking pings won't offer any benefit. - if you're having issues with your Internet connection and you call your ISP, they're probably going to try a ping to see if your connection is online. Blocking pings makes technical support difficult! The above just represents my thoughts, but if anyone reckons I'm wrong about something please do speak up!

The effect was that I could login on the GDM screen but when Xwindows started, pressing any key would only produce an alert sound. This effect suddenly appeared one day. Postings on the Ubuntu Forum (from where I got the cure) showed a few people have experienced this before. The cure was; within Xwindows press Ctrl+Alt+F1 (worked within X despite the 'alert'). Now in command line mode, run 'sudo aptitude install sandwich'. I would appreciate if anyone could explain to me as to what 'sandwich' is and how it works?
