Do you know that you can send and recieve files through phone line without internet connection? there are many telnet programes that you can use for transfering data if you have Windows, you can send files to your friends by HyperTerminal. i want to learn you how you can send and recieve files. first open HyperTerminal, click Start > Programs > Accessories > Communications >click HyperTerminal. Click File > new connection , in dialog box enter a name for your connection and click ok then enter your friend's phone number and click ok ( if you want to send file, you should inform your friend to run HyperTerminal and select " wait for a call" from Call tool bar.) now Click on call icon and then clik Dial, after Modems negotiation you can send your files. for these click on "send file" from Transfer tool bar and browse for your file. After transfer click on Disconnect icon.

Wow, I've known about TelNet for a while now, but never had the occasion to try it out... It would be very convenient to actually transfer data over the phone... also it would be a lot more secure when you're looking at avoiding the intense scans major intel-agencies use to see what you're up to.. All I can think of doing is passing along a few pictures or documents or even presentations... All this while I've used IM apps. to transfer files to friends. But like I said, where you'd want to avoid having people looking into your work, TelNet sounds like the best ticket.

The drawback as I see it, is that most people have a slow dial-up modem that the TelNet facility will use. So, if one's got a large file to send to a friend, like the most recent videos of your pajama party, (which would no doubt be a large file; assuming a 1 hour party would notch up a good 300 GB compressed with DivX) then using your modem to send a file over a TelNet connection would take a bit of a while. Especially so if the connection is across a vast distance and more so if the data has to be transmitted through copper wire cables.

The position with files now days tends for any transmittable data to be rather large. What I mean is that a conventional modem is just 'not' suitable for transfering the kind of data exchange most people carry out now days (I make a whole bunch of presentations, most of which are between 10 and 15 MB; and over a 512 KBPS line, it takes between 6 and 10 minutes for one file to transfer if I use e-mail and around 4 minutes if I'm using an IM or FTP).

Laughable as it may sound, I've never used the modem on my computer and now I'm itching to try out the TelNet feature. I'll just 'have' to dig up someone to experiment with trying a few large and small file transfers.

This Telnet thingy reminds me of a technology that is very hot right now: voIP, or voice over Internet Protocol. voIP is a way to turn analog phone signals into digital signals that can be sent over the Internet. In other words, you get to make phone calls via your Internet connection instead of through your phone line! voIP allows you to enjoy savings as it's often cheaper to send data through the Internet than a phone line.

Telnet has been around since the 80s and is what companies used for data transfer between sites in the old days. The existence of broad band wide area networking was build from this foundation and still uses the same principles.

Network specialists still use telnet as their #1 tool for troubleshooting routers and firewalls etc.

[QUOTE]
The Telnet protocol was first defined by Postel in 1980.
The purpose of the Telnet protocol is to provide a fairly general, bi-directional, eight-bit byte oriented communications facility. Its primary goal is to allow a standard method of interfacing terminal devices and terminal-oriented processes to each other. It is envisioned that the protocol may also be used for terminal-terminal communication ("linking") and process-process communication (distributed computation).
Telnet is designed to allow a user to log in to a foreign machine and execute commands there. Telnet works as though you are at the console of the remote machine, as if you physically approached the remote machine, tuned it on, and began working on it
Now that the World Wide Web has become the preferred way to access most resources, Telnet is seldom used, Except for special applications system administration. And to access archaic systems.
It was also originally designed to access information from libraries and is still today.

cool i never knew about this program. just read about your tutorial and one thing i think you might have forgotten is that the user have to have a hyperterminal thingy open aswell to wait for the file.

i dont know but its quite a logical thing to do, aint it?

im pretty sure telnet was around when ArpaNet was first tested in the early 70's i think, maybe in the late 60's. im not sure.

Telnet is fantastic !
its basically a tool for talking directly to a server.

have you guys ever sent an email via telnet ???
its quite easy http://www.yuki-onna.co.uk/email/smtp.html

infact, almost all the internet protocols are mostly plain english,

http, ftp, smtp, pop all work with telnet.

Yeah, telnet has been around for ever, it is which with everything started...

Today, there is a better, an enhanced version of telnet available: PuTTY

PuTTY is a free implementation of Telnet and SSH for Win32 and Unix platforms, along with an xterm terminal emulator. It is written and maintained primarily by Simon Tatham.

see http://www.chiark.greenend.org.uk/~sgtatham/putty/ for details and download. The program adds important security features because it uses SSH.

Just my 2 cents,

Aaah PuTTy - my love.. I couldn't travel a mile without PuTTy on my Flash Drive It's one of the most useful utilities I've come across in recent times - and I'd give it a straight 10/10 in terms of usefulness and another 10/10 on overall everything (lightweight, extremely fast, hordes of features)...

Incidentally, you might consider using WinSCP too - which is the Secure version of FTP - from what I gathered, it uses the PuTTy engine in the background to connect and then makes the FTP transfers ride on this SSL link. Very handy.
