Troubleshooting¶
Here are some suggestions for troubleshooting KeeAgent.
Common issues¶
Problem:
After upgrading my OS, my 1024-bit RSA key no longer works with KeeAgent in Client mode.
Solution:
OpenSSH dropped support for RSA keys <= 1024-bit in v7.6 because they are no longer considered secure. This version of OpenSSH ships with Ubuntu 18.04 and macOS High Sierra. Create a new, larger key.
Problem:
Connecting to a server fails when too many keys are loaded in KeeAgent. For example, you might get an error message like this:
Server sent disconnect message type 2 (protocol error): "Too many authentication failures for user"Many servers will only try the first 6 keys before returning an error. This number will vary from server to server though.
Solution:
To work around this, limit the number of keys that load automatically, use the Show selection dialog when a client program requests a list of keys option or consider having the keys saved to a temporary file as described in Tips and Tricks.
Problem:
When I start KeePass, I get an error message like this:
The following plugin is incompatible with the current KeePass version:
Have a look at the plugin's website for an appropriate version.
Solution:
Run KeePass.exe from a command prompt with the --debug option (and --saveplgxcr
for KeePass versions older than 2.31). This should give more detailed information
on the cause of the error. Report the error using the link for other issues below.
Problem:
Keys will not load with the confirm constraint.
Solution:
On Windows, if you are using Pageant and running KeeAgent in client mode, then constraints will not work. Pageant does not support constraints.
On Linux, if you are using a GNOME based desktop (includes Cinnamon, MATE, Unity, others), follow the instructions for disabling the SSH agent in GNOME keyring.
Problem:
“The plugin cannot be loaded A newer .NET framework is required.” error on Linux and KeePass version is less than 2.52.
Solution:
Use workaround described in issue #343.
