This is probally off topic. But i will post it here so everyone can see it. Since I innitiated my Captcha program on my BBS. Its been keeping the bots out and I have not seen any attempts at seeing any scripted bots trying to logon using SSH,ROOT,ADMIN ETC...
With the help of another sysop he made a scripted batch file that changes the captcha number every 10 minutes, so its not the same with every login. I am still working on the process of using the Randam INT, but am having problems trying to get it to work with the compare. So if anyone wishes to use it. I do have it posted for Download on Vert. and if we have any programers out there in Baja that want to help me improve it feel free to drop a line.

Re: CaptchaBy using that, wouldnt that only allow if the script picks 0?

i want to COMPARE I with the STR
anyways, those bots will not solve your capcha. they will get confused and sit on the connection.
Got it running, had to tweak some things.
made it start before anything else. then load the login matrix as a xtrn_prog.

so you have something for the bots to sit there and perhaps loop back if they enter any input.
and your users have to enter a long number each time.
i would rethink that.
Re: CaptchaI could always rewite it so that a user has to press a key, but so far its working and i get no complaints yet.

If his goal is to experiment with/learn Baja, then he's achieving that. If the goal is keep bots from tieing up nodes, there's much easier solutions. If the goal is prevent bots from trying to authenticate with a username and password (why?), there's easier solutions (e.g. just prompt for a specific key, like ESC).
Actually letting a bot send a username and password is a good way to detect and auto-block them and that support is built-into SBBS: https://wiki.synchro.net/howto:block-hackers
and in my case i block all the ones that fail my challenge code. so, eventually the .can file gets so huge it slows down synchronet.

Maybe you should rethink that design then.
