 Not to get too political, but is this for the Rainbow Family 
Gathering?  (First thought based on location/duration.)


 I haven't dealt with Blaze, but depending on your event's tax status 
(NPO/charity?), you might be able to get some help from local-ish 
business.  I know some of the ISPs in the Salt Lake valley have been 
known to do some pro bono work; I'm not sure about Utah County.  (Google 
Fiber in Provo springs to mind, but I don't imagine there's any way you 
could get a signal down Provo Canyon or over the mountains.)


 Otherwise, Zach's suggestion aside, I'd see whether any businesses in 
Heber proper might be able to lend/sublet you bandwidth, and look into 
point-to-point wireless.

Wireless Connectivity - Heber City, UT area

[Brandon Galbraith]

Hello NANOG!

I'm doing some research regarding short-term (~1 week) high speed (~10-15Mb
down/at least 5Mbps up) wireless connectivity in the Heber City, UT area.

The only provider I found was Blaze (http://www.blazewifi.com) (besides
ILECs/incumbents). Does anyone have any experience with them? I'm also open
to other provider suggestions I might be missing. The potential usage site
is about 10 miles LOS east/south-east from downtown Heber City.

Thank you!

Re: Linux router traffic monitoring, how? netflow?

[Adrian Minta]

Softflowd is also nice, supports "Netflow versions 1, 5 and 9 and is 
fully IPv6-capable".

The package is included on ubuntu & debian.

Apex, NC.  Been out for about a week.  I get a /128 for my router, but
no prefix delegation.

Re: Linux router traffic monitoring, how? netflow?

[Peter Phaal]

You might want to take a look at the Host sFlow SourceForge project:
http://host-sflow.sourceforge.net/

The hsflowd agent used the sFlow protocol to export interface
counters, host performance statistics and packet flows (collected
using iptables ULOG).

Southwest OH (Cincinnati) here.

I woke up earlier this week and saw that I had been seemingly ‘renumbered’.  
I.e. my DHCP PD prefix had changed (so did my IA /128).  PD was renumbered out 
of a totally different /32 at that.

I’m using wide client on Ubuntu.  wide seemed to do okay with the change, but 
the kernel forgot it’s RA def gw so I had to go full Windows and reboot the 
firewall :)

RE: Linux router traffic monitoring, how? netflow?

[Joe Loiacono]

If you go the netflow route you might consider FlowViewer/SiLK for the 
collector/analyzer. It is web driven and allows you to easily establish 
traffic thresholds which will generate an alert email.

Re: TWC IPv6 access ...

[Jorge Amodio]

Hey David, thanks for your msg.

I'm in San Antonio, TX.

Got a brief response via FB:
"There is currently an area issue ongoing. We are working to restore
services as soon as possible. My apologies for any inconvenience."

BTW, after the brief outage the DHCP served assigned a different IPv4
address.

NFDump [1] also is good if you look at a less fancy analyzer (cmdline
based) but very customizable. You search for that data the you want in
the time slot that you want.

I know there are other projects which can read captured data and present
it in a GUI but I haven't used them myself.

leonardo
