SSH servers for TTSSH evaluation

TTSSH, an SSH extension of Tera Term supports SSH1 and SSH2. SSH1 protocol and some cipher algorithms are not supported by current OpenSSH.

These docker images can build SSH servers for evaluate followings:

• SSH1 protocol
• 56bit DES on SSH1
• camellia128/192/256-cbc/ctr
• blowfish-ctr
• cast128-ctr
• 3des-ctr

Docker images

• openssh
  • port:8022
  • user:ttssh2, pass:ttssh2
  • for SSH1 (DES, 3DES, Blowfish), SSH2(camellia128-cbc, camellia192-cbc, camellia256-cbc, camellia128-ctr, camellia192-ctr, camellia256-ctr)
  • OpenSSH + camellia patch + enable 56bit DES (SSH1)
  • Cent OS 6, OpenSSH 5.3p1, OpenSSL 1.0.1e
• twisted
  • port:5022
  • user:ttssh2, pass:ttssh2
  • for SSH2 (blowfish-ctr, cast128-ctr, 3des-ctr)
  • Twisted Conch sshsimpleserver.py
  • Cent OS 6, python-twisted-conch-8.0.2, python-crypto-2.0.1, python-2.6.6
• dropbear
  • port:9022
  • user:ttssh2, pass:ttssh2
  • for SSH2 (3des-ctr)
  • Dropbear
  • Alpine Linux 3.3, dropbear-2016.72-r0

Usage

docker-compose up -d
docker-compose logs -f
docker-compose down

To maintenance image

interactive shell

docker-compose exec openssh /bin/bash
docker-compose exec twisted /bin/bash
docker-compose exec dropbear /bin/sh

build

docker-compose build --no-cache
