Re: [WISPA] System Builders WAS: Seagate 7200.11 Hard Drives

They were flashed with the wrong firmware and experience a countdown of sorts then eventually fail. Again, if in a raid, they will essentially fail at the same time if installed at the same time.

Re: [WISPA] Customers routers backwards?
Some alternatives exist as well, such as blocking the MAC addresses of the LAN ports of the router at your APs. You could do this at the switch level with something like port security, or with an ACL/firewall rules. Charles Hooper wrote: Block incoming port 68/udp from clients?

Re: [WISPA] Internet for festival: Laptop/PDA signal strength?
I like your thoughts. Cost wasn't the issue - we hadn't even talked numbers. I basically introduced myself and they told me that they weren't interested. Gotta be honest though, the lady on the phone sounded pretty old school - called my email a letter ;) I'm considering doing something similar to what you said about the trailer. There is a parking garage that overlooks the main vendor areas. I think I could put an AP up there and set up a backhaul between there and the closest 'net access. Part of my challenge is that I don't have any infrastructure in place here. I've worked at/with ISPs but I'm new to the WISP game but very interested. I'm keeping my eyes and ears open for opportunity. Thanks for the advice, Charles Mike wrote: If cost is their issue, consider revising your plan. I have found that festivals and things like farmers markets are a wonderful place to market. I have a trailer set up with a solar panel that keeps a deep cycle battery charged. I can put it in place then push up a fiberglass pole to connect to one of our tower assets. I then have an AP inside the trailer. It works for quite a radius around the setup. The side of the trailer says Awe Solar Unit and has a stylized sun. The green mileage I get just from that is noticeable. If you just set it up at some location at the festival, it would be popular and appreciated by a certain subset of revelers. The locals will take note and it puts your name out there with them in a sort of gee wiz way. Cheap, effective marketing.

Re: [WISPA] Internet for festival: Laptop/PDA signal strength?
The 300,000 people is spread over 3 days. Only a subset of those will have smart phones/PDAs/laptops, and even a smaller subset of those will want to get online. My primary target is the 100 or so vendors. Greg Ihnen wrote: How many of those 300,000 will be connected simultaneously? Isn't the limit of what a Bullet can adequately handle somewhere around 30 clients? So with three Bullets what you'll be able to support is around 90 simultaneous clients. I think you'd be better off to use clusters of NS2Locos arranged radially as sectors (plus ethernet switches, power supplies etc), and you're going to need something (MT?) for bandwidth management and also a pretty big pipe to feed it all. It might even be worthwhile to only allow traffic on web and email ports. Who knows what people are going to connect to your network. Someone with a Bittorrent client running? Someone with a Mac doing their iDisk backup? A PC doing a Carbonite or Mozy backup? If you don't pull this off well you'll just frustrate a lot of people and yourself.

[WISPA] Mobile or Temporary Internet?
Hello, I'm trying to provide wireless Internet to a local festival this summer. My plan is to set up temporary APs as there isn't any coverage in that area already. I don't have any towers in the area (or any at all) so my thoughts are that I would have to talk some local building owners into letting me put some small antennas on their roof. Do you have any tips for negotiating these kinds of deals? Alternatively, I've seen a few people mention using satellite Internet; I'm wondering who you all use?

Re: [WISPA] Mobile or Temporary Internet?
Is there any reason you recommend SilverLining over similar services such as Open-Mesh? Jerry Richardson wrote: If you are an IKANO reseller you can order a contract-less DSL to a nearby address but I would partner with one or more local businesses to use their Internet. Satellite will work so poorly nobody will use the service and it's rediculously expensive. Set up a SilverLining account and use these: http://www.silverliningnetworks.com/store/. These mesh repeaters are ISP-agnostic allowing you to use any ISP yet run from a single account and they are cheap enough you can springle them around. Alternately you could use any device router capable of supporting OpenWRT flashed with SilverLining's version. With this setup you can provide free ad-supported WiFi and paid ad-free wifi on a temporary basis, show how well it works, and possibly sell some networks to some downtown associations, or Cities.

Re: [WISPA] Bridge Network - ARP Poisioning
If you find out which MAC is the offender you can follow your bridging/MAC address tables back to the source of the chaos. It's possible that the MAC is spoofed, as well, but you should at least be able to figure out a general idea of which AP the attacks are coming in from. You can find out which MAC is doing this either by running a sniffer or running a piece of software on the bridge called arpwatch Hope this helps!

Re: [WISPA] Speed test
I can confirm this to be true. An ISP I worked at had issues with packet loss (collisions) and speed on a 50Mbit OPTEMAN circuit (ATT's Optical Ethernet offering.) Hard-coding the duplex and speed on that interface resolved the issues. Jeremie Chism wrote: snip From what I understand, with a pipe that size auto negotiate is the main problem. WISPA Wants You!

Re: [WISPA] Blocking UDP traffic
MDK wrote: Yes, for some reason, star-os routes private ip's toward whatever your default route is. GAAK! This is normal behavior for most (maybe even all) routers, provided that there isn't an access list or firewall rules in place to prevent this. There are plenty of legitimate reasons to route these IPs. They are non-Internet routeable, not non-routable. To trap these, just put those IP's on a dead end, like attach those networks to an ethernet port on your ap's or something, and they die there. You DO route at the AP, right? You can do that or you can null-route these addresses. I don't know how this works in StarOS; Many times, if there isn't a null interface or an explicit null-route option people will just add a route for those networks using an unused IP address as the gateway. Routing to localhost might be dangerous as the router may keep forwarding the packets (to itself) until the TTL expires. This could unnecessarily increase load on the router and degrade performance.

Re: [WISPA] Pan flutes on the tower
Have you tried plugging the ends of the PVC to see if the sound subsides? If you're lucky, it's not the antenna but the sound of the wind passing through the pipe (it sounds like it gets windy up there!) -- Charles Mike wrote: A while back, the amateur community talked me into putting a ham antenna on my highest tower. It is a dual band 2 meter 70 cm DC grounded unit (as per my specs). I built a mount which offsets the stick a couple feet from the tower. A piece of 1 inch PVC through which I passed a piece of poly rope is attached with stainless hose clamps near the top of the stick to lasso the 17 foot stick to keep it from swaying. A couple times this winter when I was outside, I heard this eerie melodic 4 part tone. It sounded like someone blowing across Pan flutes. Now that spring has sprung, every time the wind blows, there is this tune again. While I questioned my sanity this winter, I do think it is coming from the amateur antenna. Although the sound is somewhat melodic and not objectionable, I fear this summer with windows open in the house, it will keep me up at night. I have this fear it will be like when I first put that tower up and put a 10 foot by 20 foot flag at the top to raise awareness in the community. It snapped so loud it would wake you from a sound sleep. One of my best nights was when that flag finally came down. Since everything was done per my requests, and I want to maintain my stead with the amateur community, how does one keep that stick from making those noises?

Re: [WISPA] Vyatta?
A year or so back an employer I worked at had issues with Vyatta on Dell hardware. It was no fault of Vyatta's; Vyatta is based on Debian and either the Debian or the kernel maintainers had decided to change/remove the network driver from that particular release. Unfortunately, I don't remember the chipset we were having trouble with. Other than that, it seemed to work pretty well. We used it for our edge routers in a high-availability setup with VRRP (or maybe it was Linux HA+Heartbeat). Tom Sharples wrote: Time to update our ancient and overloaded main router.

Re: [WISPA] Wondering if STP would help in this setting
Hi Greg, I'm having a difficult time understanding the diagram, but I'll throw in my $0.02 anyway. STP is useful for allowing redundant physical paths (layers 1 2) and preventing bridging loops. It operates at the data link layer and is not a routed protocol. In other words, STP traffic will stay confined to the broadcast domain it is operating in. It is true that STP would allow you to fail over from a wireless connection to a wired connection (or vice-versa) provided that the segment between sites is bridged. My concern is that each time a spanning-tree hello packet is lost, the network will re-converge. During this 30-50 second period, spanning-tree would put all involved ports in a blocking state. IOW, they will not be forwarding traffic and the network will be down during that period. You could use Rapid STP, however, you have to take note of many different vendors' implementation of STP. For example, Dell PowerConnect will operate using Rapid STP up until you plug a regular STP device into the network (ie: a Linux box with bridged interfaces). You will also want to take note to filter STP packets from the edge of your network, customer sites in particular. I hope this helps.
