Re: Cell-based OOB management devices

I would look into Uplogix. I've seen them demo their products at Cisco Live a couple of times and they seem very good. - You can connect a cellular modem to them. - They can store backup device configs. - They can store IOS images. - They can even xmodem an image to a device if it gets stuck in ROMMON. - Some of this can even be automated by their device. ------Original Message------ From: David Hubbard To: nanog(a)nanog.org Subject: Cell-based OOB management devices Sent: Nov 7, 2011 1:14 AM Hi all, I am looking at cellular-based devices as a higher speed alternative to dial-up backup access methods for out of band management during emergencies. I was wondering if anyone had experiences with such devices they could share? Devices I've found include Sierra Wireless AirLink Raven X, Digi's ConnectWAN 3G or 4G and Opengear's ACM5004-G. I have no experience with any but they all appear to support the Sprint network which I assume would be ideal due to not having usage caps on data (currently). The Opengear device runs linux and has four serial ports, a usb port for additional storage and ethernet, so it seems to have some small advantages over the others since it could double as an emergency self-contained management station you can SSH into and run diagnostics from. All appear to have VPN/gateway support. What none of them are clear on is how you would connect to it over cellular since I assume you're just paying for a typical data plan and it will randomly obtain IP addresses. Maybe some type of dynamic dns service so you can easily figure out your device's current IP? How stable is the access to the device? Any idea if any of them can do ipv6? Thanks! David

FYI.

Previous version of Android phones supported IPv6 on WiFi and LTE. Cameron

TATA problems?
by Todd Snyder 07 Nov '11

07 Nov '11

We seem to be having some problems with our tata links - first seen in EU about 45 minutes ago, now we're seeing problems in NA. I'm focused on DNS, so I'm seeing a lot of timeouts/servfails, but our networking folks are talking about links dropping. Anyone else seeing oddness on the NA Internet right now? http://downrightnow.com/ confirms - something is up. cheers, t.

mtu question. more should be better, right?
by Deric Kwok 07 Nov '11

07 Nov '11

Hi all When I setup the server mtu as 9100. why I have to configure the switch mtu 9300 to make it working? What this extra 200 bytes is for what purpose? ls it standard? What is disadvantage of setting our all internal networks (host / equipment) mtu more than 1500? Thank you for your advice.

Router and interface naming convention survey
by Joseph Chabarek 07 Nov '11

07 Nov '11

I am doing a survey to see what naming conventions are used for routers and router interfaces as part of a measurement study that I am conducting as a student at the University of Wisconsin Madison. If you are interested in participating please fill out my form at: https://docs.google.com/spreadsheet/viewform?formkey=dE1OYmVGcjlxV1YtZjB1Qm… I am aware that this issue has been discussed extensively on nanog (and other lists). The purpose of this survey is to see in a structured manner which networks use which conventions, and get an idea for how automated the process of PTR record generation is across different providers. I am happy to provide high level results from the survey to anyone that is interested. Thanks for any feedback! -Joe http://www.cs.wisc.edu/~jpchaba

Historical records of IP allocations
by Louis P 07 Nov '11

07 Nov '11

Hello, Does anyone know if it's possible to get old records (AS numbers...) of an IP allocation ? I found on RIPE these data : ftp://ftp.ripe.net/pub/stats/ripencc/ But only the country and allocation date are included. The IP range I would like to have more information about is 109.190.0.0/17 (it was Russian before and now French). Thanks in advance, Regards, Louis P.
