Matthew. · 01-19-2007, 12:36 PM

Code has been updated!

The code now outputs the result of the domain check before checking the next one which means real time results!

champ_rock · 01-20-2007, 01:43 AM

Sure thing, i am now going out for the day however if you will wait until about 7/8 GMT then i will get it up for you

champ_rock · 01-20-2007, 01:52 AM

thanks

plus one more suggestion.. you can add 2 text files.. one for the taken domains and the other for the available ones.. if it is not too much of a coding task..

adding some reps

DJ · 01-20-2007, 04:22 AM

Matt, excellent script, been looking for this for ages!

One tiny suggestion, please add support for .tv

Thanks again and rep coming your way!

champ_rock · 01-20-2007, 05:08 AM

thanks a lot

May I kindly suggest this be an option rather than default - i.e. 'download output as text file link' please?

Also, another vote for .TV support

Wicked little script Matthew, well done.
Rep added.

Okeysss,

Sure thing, this will hopefully get done tonight, it's only a small adjustment however I'm a little tired out and have work to do

But I'll try my best!

Awesome

I haven't tried how many it can handle, theoretically it's unlimited however depending on config the server will end the script at some point.

Wouldn't dream of anything else

I will look into adding .TV support as well

Thanks for all the kind comments and rep guys

vincenzo · 01-20-2007, 10:43 AM

Hi Matthew,
Just one last thing. As the list of tld's is quite long, and to save alittle on server processing, why not have them as tickboxes?

Many people would only be interested in checking a few of those tld's anyway?

Many thanks again.

- Vince

champ_rock · 01-20-2007, 10:51 AM

the script rocks n its current stage only.

i seem to be giving suggestions and suggestions only.. here go a few more to make it a dream script kind of a thing.. they all will require more advanced editing..

1. take input also from a text file.. use cronjobs to schedule checking
2. mailing the available domain list so that the script mails me when some domain becomes available for reggin ..
3. ad proxy support which will automatically switch proxie after some 100-200 domains checks.. that way the ip will not get banned

The server list is long however the script does not check each extension. It will use the appropriate array key (and in this array since it is a multidimensional array the array array key) so check only the whois server for the domain with that extension.

I like the first half of that idea, but the second would require greater input from the user and goes out of the bounds of this script

I think i'll leave it as it is, if someone wants to do that they can but i don't have any time to spend on this anymore as i loose a whole day of work tomorrow. I will get some suggestions put in (i.e. text files and .tv support) but not extensive ones
