NAME

amigassh

SSH2 for the Amiga, 68000+. Needs a server that supports the used crypto stuff.

It will work on an unaccelerated Amiga but establishing the connection takes

about one minute.

An A3000 will

-p <port> define a port

Open a shell on the host using your console colors and mouse.

Or execute a command via SSH2.

HISTORY

amigassh V1.21

A3000 ~ 32kB/s

V4SA ~ 630kB/s

amigassh V1.20

A3000 ~ 30kB/s

V4SA ~ 580kB/s

amigassh V1.19

Note that only unprotected key files do work with amigassh.

A3000 ~ 20kB/s

V4SA ~ 400kB/s

this twice as fast as before!

amigassh V1.18

Normal Amiga applications do work on ApolloOS

Stuff from C:bin/ is still broken. /shrug

amigassh V1.17

not available volumes are denied and result into: not found.

An A3000 will copy with ~10kb/s, a Vampire with up to ~180kb/s.

The libcryptossh.library was built using my new simple library approach

amigassh V1.16

amigassh V1.15

amigassh V1.14

amigassh V1.13

This increases the chance to establish a connection on slow Amigas

* creating a key pair is down to 43,2s!

* verifying the host is down to 2:14,6!

amigassh V1.12

amigassh V1.11

Now 16 bit integers are sufficient!

amigassh V1.10

amigassh V1.9

Necessary since too many stuff checks for the string `xterm`...

amigassh V1.8

CTRL+C is handled only by the host

amigassh V1.7

amigassh V1.6

amigassh V1.5

amigassh V1.4

amigassh V1.3

amigassh V1.2

amigassh V1.1

amigassh V1.0

SYNOPSIS

amigassh [-p port] [user at ]host[:port]

The port defaults to 22.

The user is read from the environment variable `USER`.

===============================================================================

DESCRIPTION

amigassh is an implementation of SSH2. The supported cryptographic methods are

Only password based authentication is supported for now.

Install the terminfo `xterm-amiga` on the remote system!

Feel free to improve it!

On many systems you have to copy it as root into `/usr/share/terminfo/x`

Pimp your `.bash_profile` to unset `LANG` since the Amiga doesn't like UTF8...

A convenient way is to add this to `.bash_profile`:

```

if [ "$TERM" == "xterm-amiga" ]; then

unset LANG

fi

```

===============================================================================

RANDOM HINTS

It's rand() pimped with time and vpos. Then SHA256 is applied. Good enough?

But who would talk about security on an unprotected system like the Amiga?

set USER=<yourname>

you can do this in `s:shell-startup`

Use the icon tooltypes to set

COMMAND a remote command to execute instead of a shell

CONSOLE an Amiga console string (defaults to CON://///AUTO/CLOSE/WAIT)

HOST the host name

PORT the port (defaults to 22)

TERM the terminal emulation (defaults to xterm-amiga)

USER the user name

install the `xterm-amiga` terminfo!

install the `xterm-amiga` terminfo!

install the `xterm-amiga` terminfo!

install the `xterm-amiga` terminfo!

try pimping the xterm-amiga terminfo.

use `tic -xsv9 -o. xterm-amiga.src`

unset the variable `LANG`

ensure you are using the sftp subsystem, on some systems it's the `-s` flag

`scp -s ...`

exist?

e.g.: list foobar:

Get https://aminet.net/util/boot/Requester.lha and run "Cancel 5" from your

startup-sequence!

Check the file ENVARC:.ssh/authorized_keys if your public key is listed there.
