net send - a wonderful skiddie deterrant

[aeallison]

draziw,

In short, I guess what I'm trying to say is that what tends to make you faster or slower than one ISP or another seems to have more to do with such things as router configurations, capacity of the line, protocols used, and the provider... most copper issues I've personally seen tend to just be a crappy line or similiar.

The crappy switches at the CO and bad copper.

zepherin,

they should just lay OC12 fiber always and sublease it cause OC12 fiber and t1 fiber are the same and if someone subleaseing it wants to change what they got they can do it without needing to have to lay more wireing (the essential problem with copper).

That is what our capacity is right now ( I think ) we have a total of 8 strands of fiber 6 being on standby.

bludgeon,

I think what you both meant is that, in a metal medium, electrons meet w/ resistance which causes interference and signal degredation.

Very accurate if not totally correct.

droby10,

you weren't concerned about what information was being given out by the use of 'net send'?

Huh?

LoggOff,

ok, i have been thinking a long time about the data speed thruput of an oc line...... or mose spacificly an oc192....... you cant just connect it into a normal computer can you? what special hardware do you need to get on installed...... for example, i have a 600mhz 192 ram box with a 6bb hdd....... that wouldnt be able to handle it would it? what would i need?

The fiber runs into a multiplexor, into CAT 5 to the router. (digital back to analog conversion here )

xxsharkexx,

I have been playing around with net send and with many net send anonymous senders. The problem I have run into that is that net send does not work without the 2 users being on the same network. Seeing as 99% of the time that I am on the computer I am not on a network that limits me a lot. Im guessing the person you messaged was not on the same network as you so I am curious as to how you did that.

He was on the same network, DHCP asigns an IP each time you log in, also I knew that he was using Win2k, so I had his IP and knew he was on the same net/subnet.

And finally Thank you allenb1963, and anyone I may have missed.

Aye... telco's don't seem to do a very good job cross-connecting at the prem, either.

All you really need is the IP address and a means of sending the SMB dialog - you don't even need to be on the same continent, let alone network.

bludgeon:

electrons meet w/ resistance from the metal that they are travelling through(yeah yeah, electrons don't travel they rise to a higher, blah blah), but the resistance does cause interference w/ the signal being sent down the wire, interference, or to be more technical, signal degradation. . .

Hmmm, with all due respect (and I might be phrasing this poorly)... it was my understanding that twisted-pair wire is twisted (in a loop, no less) such that any interference with the circuit ends up crossing the loops in opposite directions - so the induced current is both equal and opposite in direction, nullifying the effect (ie. cancelling the effect).

At the same rate, optical signals through waveguide devices are susceptible to the same types of interferences as copper and will experience the same types of loss (though there are probably relatively fewer naturally occuring sources of optiocal noise "at room temperature" - LOL).

Thank you very much for the help. I have never been on such a positive MB before. Im really glad I read about this place. Normally a newb question like that would get flamed.

We've had a fiber connection installed recently too (at work)... The main advantage is for the ISP: the fiber (at least the equipment they installed us) can support up to 10Mbps, and they rate limit us to 1Mbps (Yeah it's actually less than a full T1: monetary reasons for now...) but they can upgrade us in no time...

As for media speeds, see http://www.nwfusion.com/newsletters/.../01416225.html
extratct:

"Thick Coax Cable: Signal travels at .77c (231,000 km/sec)

" Thin Coax Cable: Signal travels at .65c (195,000 km/sec)

" Twisted Pair Cable: Signal travels at .59c (177,000 km/sec)

" Fiber Cable: Signal travels at .66c (198,000 km/sec)

" AUI Cable: Signal travels at .65c (195,000 km/sec)

And I think someone was asking the throughput of an oc-192:
OC level base speed (OC-1) is 51.84 Mbps
Each level indicates a multiple of the base speed, so oc-192= 51.84Mbps * 192 = 9953.28Mbps ( or 10Gbps...)


Oh and..

I have had downloads reach over 700kps.

Downloads of 700 kilometers per seconds?!!

Great info ammo. So how far can you run thick coax without boosting the amplitude? And is it as cheap as fiber?

[ammo]

Thick coax is 10base-5
(Thin is 10 base-2)

10 base-5 standards state a "thick" segment should be no longer than 500m (hence the 5 in 10 base-5...)

as for cost, I have no idea, never used it, and most probably never will...

The thing is, signal propagation speed in teleco purposes isn't quite as important as througput (and distance...)

So eventhough thick as higher propagation speeds, the clear winner is still fiber, because of throughput and range...

Thanks ammo.

Excellent, excellent strategy! Didn't understand everything you did to catch this guy (I'm certainly no ISP admin), but I loved the net send solution!

I stand corrected...

attempts of hacking into the system

I recieved a neg reaction from someone who thinks this is bad jargon, so I will try very hard to refrain from mistaking "hack" for "crack".

My apoligies to the person who chooses to remain anonymous, and thinks me an retard.

Sorry for the bad grammer, but....

P.S. thanks for the little grey box.
