telnet useful, can it be again? need some help remembering

[_The Doctor__]

Did you know telnet has been used to emulate many other web functions? I ask this because I can't remember how to do it all and while I do see it should all still work.... as the registrars and other servers all say the legacy connection still remain and will continue to remain... I can no longer find the macros and scripts I used to do things....

 

For example pulling a web page.... yes you can do this on your Atari via telnet... how useful it can be is a matter for you to ponder...

this link gives a few examples..

TELNET can be used to performs querys and emulate other things as well......

telnet to ports 43 and 53..... why is that something to do?

 

well...... whois and dns......

the whois format changed on me but it still works...

it indeed still works.... with that being said...... using macros and scripts in your terminal program is sometimes needed to prevent time out's and prevent typo's

I had text files to ascii send in some terminals on the Atari and macros on the likes of bobterm...... of course even if I found them again the format and such is slightly changed and would need to reflect the changes

DNS......

 

as little as 3 or 4 years ago... you had a handful of web sites showing how to get dns servers to resolve a registered domain name for you using telnet.... this absolutely was timing critical and either you were on the jazz to type it by hand and be successful or you had to use a macros / scripts to make it happen..... this was done by the emulation method to the sever and there was a specific no yielding method to the madness...

 

none of what I have shown you will look pretty on your terminal.... but.... you can spot the useful stuff fairly well....

 

the methods to do this might be considered spoofing, faking, or emulating but none the less for our machines it's very useful..... I have set you in the direction to recover this messy and lost art... who will be the first find the site that had the procedure listed or who might look into the arcane and roll their own and re discover the method.... or like a number of us.... who will look at the network streams trying the different ports/methods, recording the results and posting their successful method first?

 

you see this is how I used my uds-10 for years..... before they made the now impossible to find file to flash the resolver into the unit... Now that there is a resurgence in the BBS interest... which I harped on for an eternity... this could all be again useful..... I feel terrible to not remember nor having properly protected this stuff... but it should not be lost... it was all on the web so in theory it can be found again. Besides everyone is orders of magnitude more clever about this internet stuff currently

Http is port 80. Just telnet to port 80 and send the proper http request. You'll get the raw html of the page.

 

Smtp is port 25, maybe? (going by memory, it's been a while since I've played with TCP ports). Telnet to port 25 and send SMTP, or ESMTP, commands.

nice to see the conversation get rolling so quickly! I am looking forward to some macro/script/success video postings....

 

one side note this is primarily to be done using dragon cart, lantronix uds, modem emulators, and yes even modems on dare I say dial up....

not sure about ape, but it's worth a try... ape resolves on it's own but you should be able to test your methods anyway as far as I can tell.

Interesting links Doc. Also, If anyone finds better firmware that will run on (and not brick) a UDS-10, please post it.

Thanks.

Telnet to port 9100 and you can send raw text to a network printer.

I've used both SyncTerm and the Lantronix in experiments to do other internet protocol stuff by changing the port.

 

Like getting a website. I've used SyncTerm and a properly formatted Http request on port 80 to get a web page response.

 

I was actually working on using this to experiment with my Atari 8-bit test BBS to update a webpage of it's status in real time. (With STar Fleet HQ, I do it with an ethernec card, but I don't have an ethernet adapter for the A8).

 

If I could find a way to have 2 Lantronix (one through the MIO and another through an 850 or P:R: (I have both) I could ACTUALLY do it in real time). At this point, it's more of a "after a user logs out".

 

 

The thing is, at some point you're not really Telnetting, but just using raw connections.
