Today i was reading about prefix scanners, as i was reading, it said that it calls a bunch a numbers and tells you if it gets a computer tone repsonse. As i was thnking, wouldnt people get ticked off to see people calling and not sayin anything?

Probably, but does it really matter? They would most likely just chalk it up to a telemarketer.

Hmm Seph,

I dont think they are much in use anymore, but the term of it is "War Dialing", problem is u can end up with quite a high phone bill.

But there used to be some really good tools out for that kind of scanning.

/me thinks back to the days of 93 / 94

Wardialers are still useful when trying to find a DATU or other pieces of telecommunications equipment which is open to the outside.

If you'd like a list, i'm sure that I could come up with some, with download sites. But I don't browse the boards much anymore, so it may take awhile. <img border="0" alt="[Blah]" title="" src="graemlins/blah.gif" />

The best tools are:

Phonesweep by Sandstorm
THC
ToneLoc

Phonesweep has probably the best interface.

the rest look for a link cause as bor said its quite outdated.

Hehe

/me laughs at the sales pitch for phonesweep

PhoneSweep
Telephone Scanning with our commercial grade wardialer, PhoneSweep let's you find unauthorized and vulnerable modems at your organization.
(or other organizations rather)

I am quite intrested by some of the functions it has.

PhoneSweep Will Dial Every Number In Your Organization

Once the Process is Completed, PhoneSweep Will
identify computers running remote-access software to bypass the corporate firewall identify over 450 systems and try to break in identify approved or unapproved modems that accept incoming calls
identify critical backup modems that have failed
Sandstorm sells hardware to go with PhoneSweep: modems, racks, and serial cards.

Its pretty refined, I might buy it.

On second thought after seeing the prices im not interested anymore, $33.700

I'm going to try to add a feature to my wardialer that allows it to play a sound file to the phone line.

LOL brought back the dead. However thats cool, now did you Program/make this wardialer or got it from someplace.

"I'm going to try to add a feature to [glow]my[/glow] wardialer that allows it to play a sound file to the phone line."

It's mine...it's still being made actually.
Supports multiple modems for parallel scans on seperate phone lines, macro text for easy log entry, lots more! The interface should allow you to attach the phone line to a mic input, and a different one to turn the line on and off. I've already designed the one to turn the line on and off (will use the parallel port). Still need to make the one for the mic input. I'm trying to find a nice way to supress ring voltages (don't want 90v into your soundcard!). So far, all i've come up with is a zener for use as a voltage limiter.

Very c00, anyway hope it goes well (was curious).

hey Psychogen...I love THC *wink* *wink*
