Graphical terminal emulator for Windows->Linux access.
13/02/2018 15:30
A few days ago UnixSpace.com announced about its new product: Windows telnet client. Don't laugh! This is a serious. The thing is that it is a graphical terminal but not X11: UnixSpace terminal - it's a realization of a telnet client for Windows. It is capable of emulation Linux and FreeBSD console, VT220, ANSI, and its own UnixSpace terminal. In the last instance the terminal has 256 colors, 4 font with 4 mode (bold | italic) , and is able to display various graphical objects (lines, rectangles, curves, etc.) as well as display gif and jpeg images. Besides terminal allows execution of Word, Excel, HTML, and other types of documents located on the Unix server.

UnixSpace terminal has 4 virtual consoles, each with individual configuration. In other words you could open 4 different telnet sessions and be able to switch between them using Alt-F1/Alt-F4, or with the mouse. It's practically a new type of a terminal device.

The second good news is: the evaluation version has not time limitation. Download it and use for free.

The steps: 1. client send to server a random number (i) using RSA public key.

2. server decrypt this number using RSA private key.

3. Server and client using this number for synchronization of the RNG.

After that: Sender: output=char+RNG[i++] -> Receiver char=input-RNG[i++]; In the channel we will have a random stream (noise). Can you decrypt this stream on the fly? It works only for stream, of course but it works.

I don't think so. I work with Unix about 20 years and I can say that this interface is very convenient for me. Alpha-betic terminal are dead, you are right. But X11 takes a lot of system recourses ant it looks ugly anyway. (it is just my opinion). Look at screen shot, probably it will be enough.

That allows you to use ssh for a gui connecion and you do not pass your loginand password as clear text across the network like telnet does.

For fun, I configured it to have 96 desktops.

If the shared RN is used directly, then there are umpteen statisticalattacks.

If this is a stream and not a block cipher, it's vulnerable todisruption by somebody else dropping their own rubbish into the stream.

Uh, no they aren't. And I would have more confidence if after 20 yearsyou could spell alphabetic.

From WordNet (r) 1.6 [wn]: alphabetic adj 1: relating to or expressed by an alphabet; lphabetical writing system [syn: {alphabetical}] 2: arranged in order according to the alphabet; ...

X has no look. That's the whole idea! It's a substrate, a protocol.

You impose your own look as you like on top of it.

If you misunderstand things so fundamentally as you give everyindication of doing, then there is no hope for you.

But it is not so important at the moment,the SSH protocol can be added late. The idea of this product is theusing the graphical objects in the CONSOLE application!

Almost all of them have been full of holes.

Security is not so important? Well, I doubt that the telnet servers on any of the hosts Ideal with have implimented your new encryption scheme.

1) That idea has been around for 25 years. Tektronix, DEC, and others all defined terminal-based graphics standards.

They're all dead. (Though xterm still has Tek 40xx emulation, AFAIK. And there's probably a REGIS terminal emulator around somewhere as well). The rather elegent MGR window system was based on graphics in the CONSOLE application. It's dead too.

2) What CONSOLE apps???
