C-Kermit is a combined serial and network communication software package offering a consistent, medium-independent, cross-platform approach to connection establishment, terminal sessions, file transfer, character-set translation, numeric and alphanumeric paging, and automation of communication tasks. Recent versions include FTP and HTTP clients as well as an SSH interface, all of which can be scripted and aware of character-sets. It supports built-in security methods, including Kerberos IV, Kerberos V, SSL/TLS, and SRP, FTP protocol features such as MLSD, and source-code parity with Kermit 95 2.1 for Windows and OS/2.
TrinityOS is a step-by-step, example-driven HOWTO on building a very functional Linux box with strong security in mind. TrinityOS is well known for its strong packet firewall ruleset, Chrooted and Split DNS (v9 and v8), secured Sendmail (8.x), Linux PPTP, Serial consoles and Reverse TELNET, DHCPd, SSHd, UPSes, system performance tuning, the automated TrinityOS-Security implementation scripts, and much more.
ssh-multiadd adds multiple ssh keys to the ssh authentication agent. These may use the same passphrase. When run without arguments, it adds $HOME/.ssh/identity and $HOME/.ssh/id_dsa. Alternative file names can be given on the command line or in the configuration file. It uses ssh-askpass if necessary. Unlike ssh-add, if any of the keys use the same passphrase, you will only need to enter each unique passphrase once, and keys that are already added will not be prompted for again.
Multixterm creates multiple xterms that can be driven together or separately. It can be used to login via SSH to multiple hosts and control them simultaneously, or for ad hoc things where you want to see the results as you type. Each xterm may also be driven separately. Multixterm is scriptable so that you can easily fire up, for example, a dozen xterms with a single command, tiled nicely on your screen. In addition to SSH, multixterm can drive rlogin, telnet, passwd, or any program that runs in an xterm.
SSHTerm is a fully-featured Java SSH terminal that provides a whole range of features including port forwarding, password and public-key authentication, full clipboard support, record and playback input/output, and the ability to load/save connection settings to a file. The SSH terminal is now seamlessly integrated with a secure VNC viewer, a port forwarding manager, and a full SFTP client.
S-terminal lets you create a secure X terminal. Regular X terminals pass unencrypted data between you the remote machine. S-terminal creates an encrypted tunnel through which all X traffic passes. It replaces the remote xdm login screen with a local application that collects username and password, then sets up an ssh tunnel to the remote host and starts a session. It is highly configurable both in appearance and behavior, and deployed S-terminals can be remotely administered. Best of all, it can be added to a KNOPPIX CD to create an instant, bootable, secure X terminal CD.
mimic is a server that mimics Internet servers. It includes imitators for ftpd and telnetd, and can be extended with scripting to support other types of imitation. Users will believe they are connected to authentic services (such as ftpd or telnetd) but will never be able to log in. Everything that they type is logged. In addition, scripting new imitator services is simple. The program includes a one-liner example of a fully-functional echo server. The project's goal is to create a script for imitating most, if not all, popular Internet services.
