Author: [email protected]
Uploader: [email protected]
Architecture: m68k-amigaos
Type: comm/net
Version: 1.40
Required: bsdsocket.library (e.g. AmiTCP)
Replaces: amigassh
📖 Overview
BebboSSH is an SSH2 implementation for Amiga systems (68000+).
📦 Source Code: https://franke.ms/git/bebbo/bebbossh
It requires a server that supports the included cryptographic algorithms.
The supported cryptographic methods are
It provides the following tools and libraries:
bebbosshd– SSH2 server daemon
bebboscp– SCP file transfer utility
bebbosshkeygen– Key generation tool (Ed25519)
libcryptossh.library020(rename and use on 68020–68040 or 68080 CPUs)

⚡ Performance
It will work on an unaccelerated Amiga but establishing the connection takes
about one minute.
Example timings on an Amiga 3000:
- X25519 key pair creation: ~0.9s
- Signature verification: ~1.2s
-v5 for DEBUG logs with timing infoExpected SCP transfer speeds (kB/s):
| Cipher | UAE-A500/68000 | UAE-1200/68020 | A3000/68030 | V4SA/68080 |
|--------------|----------------|----------------|-------------|------------|
| AES-GCM | 6.6 | 35.6 | – | 317 |
| ChaChaPoly | 5.8 | 32.2 | – | 351 |
020 library version:
| Cipher | UAE-A500/68000 | UAE-1200/68020 | A3000/68030 | V4SA/68080 |
|--------------|----------------|----------------|-------------|------------|
| AES-GCM | – | 44.6 | – | 353 |
| ChaChaPoly | – | 60.1 | – | 396 |
🛠 Programs
`bebbossh`
SSH2 client for interactive shells or remote command execution.Supports config files, key authentication, port forwarding, verbosity levels, and cipher selection.
`bebbosshd`
SSH2 server daemon.Provides terminal emulation and SFTP file transfers.
Requires configuration in
ENVARC:ssh (config, keys, passwd).`bebbosshkeygen`
Generates Ed25519 key files.`bebboscp`
SCP utility for copying files between local and remote systems.Supports wildcards, config files, key authentication, verbosity, and cipher selection.

🕑 History
BebboSSH v1.39
- Consolidated crypto with BebboGet
- Rewrote AES for speed improvements
- Improved ChaCha20-Poly1305 performance
Previous Versions (AmigaSSH)
- v1.38: Added ChaCha20/Poly1305, config file support for ciphers
- v1.37: Speed enhancements, faster key generation and verification
- v1.36–v1.29: Various fixes, SFTP improvements, ESC handling, channel management refinements
RANDOM HINTS
- the know hosts are stored in
ENVARC:.ssh/known-hosts
- the random generator is not the best...
But who would talk about security on an unprotected system like the Amiga?
- preset your username with
you can do this in
s:shell-startup- you can start it from the workbench!
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 nameinstall the
xterm-amiga terminfo!install the xterm-amiga terminfo!- no mouse in mc or other applications?
xterm-amiga terminfo!- keys not working properly?
xterm-amiga terminfo!- can't install xterm-amiga and have to build it for my system?
tic -s xterm-amiga.src
- some key does still not work
use
tic -xsv9 -o. xterm-amiga.src- console displays trash? text look blank? lines are bogus?
LANG- scp to bebbosshd: closed remote port
-s flagscp -s ...- your remote Amiga is blocking coz you accessed a volume that doesn't exist?
Get https://aminet.net/util/boot/Requester.lha
and run "Cancel 5" from your startup-sequence!
Or try https://aminet.net/util/cdity/OkayDokay14.lha.
- public key authentication does not work!?
public key is listed there.
- can't scp to a server named 'ram', e.g. amigascp c:s* ram:folder
myname@ram:folder
- the program aborts with a message like "can't resolve _Z9splitLineRPc"?
- ensure that you are using the recent libcryptossh.library
- if you just updated bebbossh, close all running bebbossh programs and run
- ENTER does not work with multiple SSH hops? Try CTRL+J
🚀 Summary
BebboSSH brings modern SSH2, SCP, and SFTP functionality to classic Amiga systems, with optimized cryptographic routines and support for both 68000 and 68020+ CPUs.
