Tips and Tricks¶

Creating URL Overrides to Open a Connection¶

Having lots of SSH keys loaded in KeeAgent can be a problem for many servers. To work around this, many ssh programs allow you to specify an identity file when connecting so that it knows which key to use instead of having to try all the keys that are loaded.

Since SSH keys in KeeAgent are usually saved as attachments embedded in the database, there is an option in the Entry Settings to save the key to an actual file on disk when the key is loaded in KeeAgent.

Once you have selected this option, there will be two placeholders available for use in KeePass.

• {KEEAGENT:KEYFILEPATH} returns the full path. e.g. C:\path\to\keyfile.ppk
• {KEEAGENT:IDENTFILEOPT} returns the identity file command line option that is used by both PuTTY.exe and ssh. e.g. -i "C:\path\to\keyfile.ppk"

You can use these placeholders to create URL overrides. Global overrides are at Tools > Options > Integration (tab) > URL Scheme Overrides… or they can be specified per-entry on the Properties tab of Entry Settings.

Note

The placeholders also work with the External File location in addition to attachments.

Example:

Open an ssh connection using PuTTY with the username and host specified in the database entry. The entry must have the Username and URL fields filled out for this to work.

cmd://"C:\Program Files (x86)\PuTTY\PuTTY.exe" -ssh {USERNAME}@{URL:RMVSCM} {KEEAGENT:IDENTFILEOPT}


Tip

Read more about the PuTTY command line here. For example, the -load option is useful to load a saved session associated with the key.

Using KeeAgent on Windows¶

Client mode with Pageant¶

KeeAgent (in Agent Mode) is designed to work much like ssh-agent on Linux/BSD/etc… Pageant is very similar, but there are some notable differences. Because of the more limited features of Pageant, it is recommended to run in Agent mode on Windows instead of using Pageant. However, if you have a good reason to run KeeAgent in Client Mode along with Pageant, here are some things to be aware of:

• Pageant does not support locking.
• Pageant does not support constraints.
• Pageant does not support ECDSA or Ed25519 keys (except in the development version).

Cygwin and MSYS¶

KeeAgent can natively communicate with ssh programs running in Cygwin and MSYS. It is enabled in the Global Options dialog.

There are two implementations of sockets that are found in the various versions of Cygwin and MSYS. MSYS is really just a fork of Cygwin, so it depends on which fork the code is based on. So, unless you are using msysGit, try the “Cygwin socket file” first and if that does not work, try the “msysGit socket file”. In some cases, you may need both enabled to support multiple versions of Cygwin/MSYS.
