Hostname creating

Ok, recently I posted to Packet Storm a small Java class along with Juman from 2600's C code for cracking Austnet's VW hostmasking. All my class did was create a list of IPs given the first two octets [ie. if given 202.132. it would generate 202.132.1.1 to 202.132.255.255]. This was used if the user was using a non-resolvable IP.Now the problem is when you want to crack a masked hostname. If their ISP allows hostlist retrieval [*ix: host -l host.com] then you just pipe that to a file, and Duane's your Auntie. BUT, if it doesn't, then I want to write a class similar to what I did for the IPs, just generate hostnames given a certain mask.An example. If it's known that the mask is dialup-##-#.host.com.au then I want to start with dialup-11-1 and end with dialup-99-9.Due to brainlock, I just can't work out how to do it. My problem is not knowing how many loops that're needed [can be any number if you think about it], and I just don't have the logical thinking to work it out.If someone could point me in the right direction, I'd be rather happy... I'll be doing it in Java [duh] and I'll happily credit whoever puts in something [that I use].

Re: Hostname creating

*polishes his dome* Lose what?What you're thinking of would be similar to simple parity checking, though, wouldn't it? You want to find if the first bit is odd or even so you apply 101010101010 to the binary value of the number you want to check, check whether it's odd/even, and I won't go into the rest because I drove myself insane doing it last year [fuck you PDP8 ASM].This is really shitting me off though... it's just trying to work out how many loops I'll need and being able to implement that. Once I've got that, it's done. *cries* I have a script that does it, but it's done in mIRC scripting :(Here is the business bit of it [I think]:Sorry for length of this...alias findip2 {

set %findip.num 0

:again

who %findip.ip $+ %findip.num $+ $chr(42)

inc %findip.num

if (%findip.num > 9) {

halt

}

goto again

}alias findip3 {

set %findip.num 0

:again

if (%findip.pos > 1) { set %findip.hosttemp $mid(%findip.host,1,$calc(%findip.pos - 1)) $+ %findip.num $+ $mid(%findip.host,$calc(%findip.pos + 1), $len(%findip.host)) }

else { set %findip.hosttemp %findip.num $+ $mid(%findip.host,$calc(%findip.pos + 1), $len(%findip.host)) }

who $replace(%findip.hosttemp,$chr(35),$chr(42))

inc %findip.num

if (%findip.num > 9) {

halt

}

goto again

}raw 315:*: {

if (%findip.status == on) {

inc %findip.replycount

if (%findip.grabip == on) {

if (%findip.findhost == true) {

set %findip.host $mid($2,1,$calc(%findip.pos)) $+ $mid(%findip.host,$calc(%findip.pos + 1), $len(%findip.host))

set %findip.grabip off

inc %findip.tempcount

if (%findip.tempcount > %findip.realcount) {

echo -a [findip]: Real Host Found! %findip.nick $+ @ $+ %findip.host

unset %findip.*

halt

}

set %findip.pos $pos(%findip.host,$chr(35),1)

findip3

}

else {

set %findip.ip $left($2, $calc($len($2) - 1))

set %findip.grabip off

if ($count(%findip.ip,$chr(46)) == 2) {

if ($gettok(%findip.ip,3,46) > 0 && $gettok(%findip.ip,3,46) 0 && $gettok(%findip.ip,4,46) 9) {

if (%findip.findhost == true) {

if (%findip.ipgrabbed != true) {

echo -a [findip]: Unable to determine real host. Stopping.

echo -a [findip]: You may wish to try an alternative host pattern if exists.

unset %findip.*

halt

}

else { unset %findip.ipgrabbed }

}

else {

echo -a [findip]: Unable to determine real IP. Stopping.

echo -a [findip]: You may have to scan for host.

unset %findip.*

halt

}

Re: Why not use recursion ?

I see where you're coming from, and I've _almost_ got my head around it...Basically what I have to do is create the following:Given dialup-##-#.host.com.au as a mask, I want to generate...dialup-11-1.host.com.au

dialup-11-2.host.com.au

dialup-11-3.host.com.au...dialup-23-9.host.com.au

dialup-24-0.host.com.au

dialup-24-1.host.com.au...dialup-99-7.host.com.au

dialup-99-8.host.com.au

dialup-99-9.host.com.auBasically I increment the first digit until it hits nine, then incremement the preceeding digit by one, cycle through values 0-9 again, increment preceeding digit by one, and so on.

Well, here's what this does...

print "dialup-10-0.host.com.au"

etc.You can improve this a little bit by not calling getdigit() again if you have no #'s left, but the difference in processing would be small anyway, so why bother.

Hey, it's a quick & dirty hack anyway :)

Re: Well, here's what this does...

I decided to look at one of my other Java books, and lo, it was there :) *starts reading* The book I usually use didn't have it in there...Thanks for helping tho

Re: Why not use recursion ?

its just gonna be as many loops within each other as as many numbers there are u wish to do stuff with

so for 2 numbers

for()

{

for()

{

do stuff

}

do stuff

}

Re: Why not use recursion ?

rightyo, recursion the way u go

good luck :)
