I tried to ask a MS rep at Automation Fair 2000, but all the guy would do was curse and say how.NET would revolutionize everything. I mentioned asked about support for non-ms platforms and the guy just kinda stood there and said nothing more.
I think.NET is really the hidden button that should be the Self Distruct to the Evil Overlord's Secret lair.
I have a fairly high traffic enviroment.... (my boss pulling pr0n from news servers on our internet connections constant......) Most days.... I see about 97% usage of the connections... Scarry huh? I haven't noticed many UDP dropped packets.... Infact... I think I'm seeing more mangled UDP packets that are failing the crc test then packets being dropped. I do have QoS enabled, which allows my web browsing... or software downloads to take his bandwidth right out from under him.
You would not need to bond ethernet interfaces. You would need four things.
1. IPTables Reference. You will be using the MARK rule, and one of the new modules that do % of time matching.
2. A working knowlage of the IP Route 2 tools.
3. Properly configured Interfaces. You will have one route that will ALLWAYS be primary, then a Secondary Interface. The secondary will will have a slightly higher metric for the default route, but you will need to "src" the packets leaving that interface, and makesure your nat rules are working properly.
4. You need to know your shit to do this. Fucking with this stuff will fuck up your access.
You need no cron job to check the interfaces. Routing does it all for you. Thats why there is this thing called metrics.
This same basic story was posted about a year ago. Hell, the dude who did it even made a post. Come on people.... Drink more coffee so your memory will be retained for more then an hour.
One of my friends from IRC once mentioned that his employeer, a CLEC, was deploying wireless internet, and that he aparently had some sort of cell phone that also would talk with the wireless gear, and would allow him to make VoIP phone calls. Sweet eh?
A legion of rednecks? Where? 6000 rednecks could only mean a country or bluegrass concert is near by!?!?!?!?! Run for the hills... Run for your lives!!!!
I have worked in the HMI/Systems Intergration Field, and there are really only two products used for design. Autocad for 2d work, and Pro/Engineer for 3d and serious acurate 2d work. The funny thing is, you can download a version of the package that is 100% free for nothing.... unless you don't want like 250 megs. True, you could order the cd for like 10 bucks. The only thing they require is that you keep registered with them. *shrug* My mom keeps trying to get me to use it so I stop looking for her Autocad R12 disks.
The problem for adoption is the price... I'm not going to buy a 600 dollor access point to have 802.11a in my home when i can buy a 150 buck access point for 802.11b.
We did that in my dorm.... we wrote a 40 line c program to DoS smb on this guy who left his mp3s playing all the time..... his software allowed him to loop playing....
It may be just your cell. The transmitters in various cell phones are very diffrent. I have a samsung m100 (the mp3 playing one). It was discontinued for signal problems, but at college, in the dorms, I was one of the only people who could continue to talk on my cell phone while in the elevator. I can get out to where there is not a cell tower in sight, and loose signal on that phone, but on my Samsung 8500 that I also have, I may still have three bars left, and I can still make calls. Another thing that bugs me with the signals, is that most cell phones say "i'm on the network" when it can recieve the signal from a tower, but You can't make a call for maybe 20 miles down the road.
I recently got a new wap11 v2.2 from linksys to put in my office on top of the server racks so I can just sit back in my chair, with my feet up on the server racks, and surf the net with my laptop. Anyway. Whenever I get a packet collission with it, the wap11 v2.2 stops transmitting packets.... odd huh? Linksys support jerked me around, and I got moved to 2nd level support once I called one of their support persons on the bullshit they emailed me. She told me to set the wap11 v2.2 to values that are not even possible to set. Anyway. I was recently emailed a new firmware image, so instead when it gets a collission, it sometimes resets, but If I'm lets say 20 feet away, Its useless, the link won't work. Atleast they have not tried blaming it on my linksys wpc11 cards.... but they did tell me to flash the pcmcia card with the most recent firmware... my response was "Didn't you know, you guy's don't let people download firmware images for your pcmcia cards". Gee... I wonder what they will send to me next week.
This is cool. Don't get me wrong, I like the Idea, and am for it 110%, but, there are other projects that need funds, like projects developing impulse and warp drive.
And maybe a faster then light communications method... Plus, we need to setup a sensor permiter of our solar system:)
I actually did price replacing my office's (both home and work) with 802.11a.... 600 dollor access points and two hundred dollar cards are just a bit tooo expensive.
No, I know my memory is not failing me, because they use diffrent encodings, at tipicly diffrent frequencies on the line. Go pull up an SDSL modem spec sheet.
Yeah, but think the cost, I mean, only people who have a good amount of cash are going to be sniffing a t1 loop. A 1SSI card from SBE (Formally LMC) costs like 800 bucks with the propritary cable.
Most make the mistake of wanting ADSL, which your at like a 4km limit on cable lenth with it. With SDSL, it can go 9.8Km if memory serves. Thats something like 4.something miles. Ofcorse, at 9.8Km, you only get something like 144kbps, but that is decent....
Cable is trivial. A pci cable modem and some good drivers will go a long way.
DSL loops, T1 loops. Your talking specialized hardware that costs more then the adverage car. Somebody once told me that a T-Bird (T1...T3 packet sniffer) cost 40 grand. I have no idea how much DSL coperable hardware would cost.... and even if such a thing exists. A T-bird can most likely sniff dsl anyway.
At 500km no, just high-gain antennas will not work.. perhaps with amps maybe, but most likely not. At that distance, you would be running into signaling problems, because both ends will be saying "hey, i'm here" every 100 ms... what if one gets off a little bit.. there goes your link.
At that distance, I would say, do what the telco's do. Big tower, Multiplexed microwave signal.
I have noticed some small ILECs are willing to do whatever it takes to make their customers happy aslong as they continue to have a positive cash flow. I know of an ILEC that for like 230 a month, they basiclly pull a t1 to your house, kick your voice over the t1, and then use the rest for data. Ofcorse, they call it some bullshit, but everybody who knows their stuff knows its a t1 line. Ofcorse... there are the ILECs that buy other ILECs out, and then do nothing. I have sprint locally. The town has been polietly demanding broadband for several years (bedroom town between two decently large cities), and they are just now, three years after they said they would in a few months, to offer dsl. Sprint Sucks.
Yeah... The cordless phones where I work have two line access, caller id, intercom, and some other thing on all the phones.... plus decent range. I can go get the mail and still be on the phone.
Repeaters are not a very good idea with 802.11b. Most likely, High-Gain antennas on both ends, and maybe signal amps would be the best bet. Or maybe long distance links between two access points, then service the local area with an additional ap or two on another channel.
