Free passwordless ssh software for linux

Passwordless remote logins script can be used to:

1: Create 1024 bit passwordless dsa keys.
2: Send key to remote server via scp.
3: Create remote .ssh directory and move key to authorized_keys file.

This will allow you to login to remote server via ssh or run automated rsync backups. You need openssh, bash and expect installed for this to work. Optionally you can create an executeButton with the following format for a one click remote server login.

The format: konsole -e ssh -i /your/path/toyour-key remoteusername"@"remotehost_or_ip

syncpasswd is an Expect script that synchronizes passwords via SSH on multiple platforms (Linux/BSD, OS X, and Solaris).

It takes hostnames as a list of arguments and changes the specified user passwords on those hosts. syncpasswd outputs results to stdout and logs to /var/log/syncpasswd.log (by default).

kaskpass is a ssh-askpass replacement for Kde. In add, it allows use of kwalletd to manage your passphrase(s).

See ssh man pages for more information about ssh system, ssh keys, ssh-agent and ssh-askpass.

kaskpass is written in ruby. It depends of ruby interpreter, libkorundum and kwallet. kaskpass is packaged to be installed in /usr/bin, but you can easily use it from your home directory.

Installation is same than ssh-askpass or ssh-askpass-gnome. One of convenient way is to copy kaskpass.desktop in your ~/.kde/Autostart:

cp /usr/share/doc/kaskpass/kaskpass.desktop ~/.kde/Autostart

This is only a beta version. There are some bugs to fix. Especially, I dont insure security of kaskpass. Please report all bug or improvements need.

ToDo:

- This is only beta version. There are some bugs to fix. Especialy, I dont garanty security of kaskpass. Please report all bug or improvements.
- Write manpage
- Translate it in other languages
- Add a systray icon to block acces to your ssh-agent
- Merge previous behaviour in kwalletd (as plugin for exemple)
- Write instructions for other distribution than debian

Cluster SSH opens terminal windows with connections to specified hosts and an administration console. Any text typed into the administration console is replicated to all other connected and active windows.
This tool is intended for, but not limited to, cluster administration where the same configuration or commands must be run on each node within the cluster. Performing these commands all at once via this tool ensures all nodes are kept in sync.
Enhancements:
- Check for failure to connect to X session
- Totally rework character mapping and events to cope with non-QWERTY keyboards
- Rework pasting code to cope with non-QWERTY charatcters
- Manpage/help doc updates and corrections
- Check for missing definitions for cluster tags in .csshrc
- Run through perltidy -b -i=2
- Apply patch to add in optional port information from D. Dumont
- Amend hotkey code to not pick up - as default clientname shortcut
- Alter repeat function to improve efficiency
- Rework retiling code
- Add "-e " to evaluate terminal and communcation methods
- Add in toggle option on hosts menu
- Fix check in find_binary to ensure one is actually found
- Search $PATH and other standard places for binaries incase $PATH is incompleteAmend code to allow getting help when no X display available
- Allow override of both key and mouse paste key sequences
- Added icons and desktop file
- Amended clusterssh.spec to cope with icons and desktop file
- Improve cluster file import efficiency as was taking faaar too long previouslyFixed bug whereby when pids of the xterm changes records were not updated
- Do not die when pipe open fails, but continue as others may be connected
- Remove code that breaks the minimize/maximise stuff;
- Catch X button presses on title bar to close all windows correctly
- Delay map event capture at program start to avoid infinite loop
- Fix execvp error on Solaris 10

DSSH was written as a direct replacement for OpenSSH client for our use. The project adds SSH over SSH tuneling capabilities (for example to log in to network which is hidden by firewall), scripting support (using Groovy), advanced agent (which allows storing of passwords) and "su -" interactive logging for machines, which have disabled direct root login.

All of this was done to enable automated scripting and logging to lots of machines based on few simple rules.

It uses Ganymed SSH library (slightly patched). I tried to contribute my changes back to Ganymed-SSH authors and if I succeed, I will probably try to stick with official Ganymed-SSH distribution.

Port forward is a java application which gives you the ability to open tunnels between your local computer and a remote ssh server.
Tunnels can be created both local or remote
Examples:
1. Open a local tunnel to reach a remote mysql database
Your application needs to connect to a remote database server (mysql for example), but the database server (remote.server.example) is not configured to expose mysql to internet directly.
Port forward will open a local port (3306) and redirect the connections to remote.server.example ssh server
The remote.server.example ssh server will connect to its local mysql server
2. Open a local tunnel to use a remove VNC desktop
You want to connect to your home computer which has a vnc server but from work, the firewall blocks vnc connections (generally on port 5901)
If you have a ssh server at home, you could use it as bridge to connect to a client in your home:
Your position internet your linux ssh server ->>
-->> you client with vnc (192.168.0.40)
you office internet >
You will be now able to connect using a vncclient giving 127.0.0.1:0 as address
3. Open a remote tunnel to pilot a remote linux server non reachable through internet
In this example, you will create a remote tunnel, this will give the remote man to connect to and reach you.
I used this example if I have to pilot a remote pc, but this pc has no static IP or is behind a firewall
The good solution is to activate port forward on the pc to be piloted and to connect it to a server we can access.
PC 1 (to be piloted) --||||-- firewall ----- internet ----- accessible-server
As you can see in this situation, if firewall does not use NAT, you have no way to reah PC 1
Enhancements:
- A button for selecting a command to execute upon connection with the server was added.
- A small problem with removing items was fixed.

Quest OpenSSH provides password-less, secure, encrypted remote login and file transfer services for Vintela Authentication Services (VAS). It is a derivative of OpenSSH, an open-source implementation of the SSH protocol.
Quest OpenSSH provides:
- default single sign on for Quest customers using VAS or VMX. Users are automatically and securely authenticated against Microsoft Active Directory using GSSAPI.
- compatibility with other SSH tools, including Quest PuTTY.
- integrated enhancements including high performance network support and TCPwrap access controls.
The software packages include both the client, ssh, and the server, sshd. Packages are subject to open source licence conditions.
Enhancements:
- This releases new features are the Match directive and inclusion of the HPN patches (High Performance Networking).
- Minor bugs fixed include NIS+ compatibility and improved service script reliability.
