Switch with 10 Gig and GRE support in hardware.
by Matt Newsom 01 Mar '11

01 Mar '11

I am looking for a switch with a minimum of 12 X 10GE ports on it, that can has routing protocol support and can do GRE in hardware. Does anyone have a suggestion that might fit. Keep in mind I am looking for something in the 1-2U range and not a chassis.

Hughesnet outage - where can I ask?
by Greg Ihnen 01 Mar '11

01 Mar '11

I run a small network in the jungle of Venezuela which is fed by a rebranded Hughesnet connection. We just had a four day failure where the only protocol that worked was ICMP and we were completely without communication. Traceroutes all failed in a bizarre way when using UDP, TCP or GRE packets but traceroute with ICMP worked fine. Our provider (Bantel) is blaming Hughesnet but I'm not finding anything to back that up in forums or in searching the web. I don't want to bother this forum's members with my questions regarding what the traceroute results show and what the problem might be. Is there another forum where these questions would be appropriate? Thanks in advance. Greg

Sunday Funnies: Using a smart phone as a diagnostic tool
by Jay Ashworth 28 Feb '11

Do you have a smartphone? Blackberry? iPhone? Android? Do you use it as a technical tool in your work, either for accessing devices or testing connectivity -- or something else? If so, what kind of phone, and what (if you don't mind letting on) are your magic apps for this sort of work? (My motivation? Well, um, Lee, I'm looking at buying an HTC Thunderbolt, if everyone can get their thumbs out, and I want to get a feeling for the lanscape, if you'll pardon the pun. :-) Cheers, -- jra

Sunday Funnies: Using a smart phone as a diagnostic tool

I use Android phones, mostly for remote administration. SSH using ConnectBot. If you want a really durable phone, with the option of a little bit of additional functionality, I would take a Motorola Droid 1, throw CyanogenMod on it with a p3droid kernel. The phone itself can survive 3ft falls @ 30 mph (proven myself on accident), the keyboard is very useable, and overall is an amazing phone. You can also use a fair number of command line tools, and add your own statically compiled tools, or dynamically compiled with a bit more work.

World IPv6 Day (was: Mac OS X 10.7, still no DHCPv6)

[1] - apocrypha of japan being ipv6 rich are utter bs.
