Wardialer for unix
------------------
Shok
Serial programming for unix.....boy this stuff is fun. Well unix
is famous for it's special files. The modem is just a file you can open(),
read(), and write() to...for that reason this program can be used on all
unixs'. The only thing different that needs to be changed, is the
#define MODEMPORT "/dev/cua1", because most unix/unix clones have their
own modem port. For example /dev/ttyS? which is COM1 (to the DOS users),
would be /dev/ttym? in IRIX. Now once this program opens the modem (via
device/special file) for reading/writing, it will write() to it, and send
it standard modem instructions like +++ATH, ATZ etc....this comes before
any dialing to get the modem ready....we also use a function to check for
"OK" so we know that all is well. On receiving this, then enter the number
we want to dial into a character buffer, append a "\r" to it (to it
actually sends the command), we then write(fd (the file desc. for
/dev/cua1), thebufwiththenum, strlen(thebufwiththenum)); Now once you do
this..you can't write "+++ATH" to it, because it will send that as the
login name (assuming you've connected to a host), so what I did, was I
opened the other modem port (there are two, /dev/cua0 and /dev/ttyS0 are
essentially the same thing (both COM1 to explain it easier), one is used
for dialing out (cua?) and one is used for dialling in and out (ttyS?). So
I opened up the other port and used that to send the command to hang up.
But all the other stuff isn't complex, they are all C primitive
instructions like ScanMin++; which would increse ScanMin by 1, repeat a
while loop, and then the next strcat(phonenum, ScanMin); ... would dial
the next number......you get the idea. That's about all there really is to
say about the technical stuff about it.
Oh yeah one thing.....when it connects, it looks for the string
"CONNECT" returned from the modem serial file. You won't get this message
from faxes as you will only get this message when the connection is
complete, so this will only return *** CONNECT *** if it was a modem. It
will both output to the screen and logfile *** CONNECT *** to
1-xxx-xxx-xxxx. You can use local or long distance, although international
numbers haven't been added at this time (not hard to do just didn't care
to add an extra scanf and an extra CountryCode variable ;)
About ShokDial (it's temp name for now)
---------------------------------------
This supports random scanning (pseudorandom to be honest, heh) and
sequential (the range you specified and up) scanning. You can give it a
range too but that still does under sequential scanning. To use random
scanning use 'shokdial -r', otherwise it will by default use sequential
scanning. For the other options type 'shokdial -h'. You want to keep track
of the version because I'd almsot guarntee this program is going to
continue changing. I need to add some ncurses GUI effects (heh) and a
function to resume scanning for those of you who are too lazy to even look
at the (by default) wardialer.log and get the last number it dialed
(assuming you used sequential scanning) and entering that as the Scan
number to begin on!
It will output to wardialer.log and on to the screen. If you have
BEEP = WANTBEEP in the Makefile, it will beep when it connects to a host.
That's about all I really have to say about it. I don't actually use war
dialers (really), so I haven't actually tested this (sorry if there are
any problems but there shouldn't be)....if you do however find a problem,
please let me know! I will fix it and send out a patched version.....you
can get all of them from ftp.janova.org or www.janova.org. Enjoy ;)
