support redirected stdin/stdout

amigassh V1.4

bad version...

amigassh V1.3

amigassh is now pure. set the flag and make it resident!
internal setting of a suitable stack size
verbose error messages
unify ed25519/curve25519 code
properly create ENVARC:.ssh if missing
some terminal improvements

amigassh V1.2

properly exit after logout, no CTRL+D required
mono now supports 8 colors - update that file!
handle key stroke repetition
bind local, needed by roadshow
fix reading after buffer pointer changed

amigassh V1.1

some support for CTRL/ALT,
better cursor keys,
better terminfo `mono`
fix if stdin is a file/pipe

amigassh V1.0

initial version

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

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

curve25519-sha256
ssh-ed25519
aes128-gcm at openssh.com
hmac-sha2-256
sha512

Only password based authentication is supported for now.

Install the terminfo `mono` on the remote system! Feel free to improve it.

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

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" == "mono" ]; then

unset LANG

```

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

RANDOM HINTS

the know hosts are stored in `ENVARC:.ssh/known-hosts`

the random generator is not the best...

It's rand() pimped with time and vpos.

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

preset your username with

set USER=<yourname>

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

You can start it from the workbench!

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

USER the user name

no console graphics?

install the `mono` terminfo!

keys not working properly?

install the `mono` terminfo!

some key does still not work

try pimping the mono terminfo.

console displays trash?

also unset the variable `LANG`
