Agent stopped to work

The Shaman Agent does not seem to work, I keep getting requests to enter my password to access a Remote Server. However, it did work through the token before.

Since it worked before, you must have successfully installed your SSH Key on the Remote Server. It seems like your desktop system has an out-of-sync problem between program components. The quick fix is usually to remove and reinsert the token and to select Reattach Shaman Agent from your desktop menu.

What can have happened is that your Shaman Agent somehow got stuck. If this happens it is usually due to lower level problems, for example at the PC/SC driver level. This can happen if you login to your desktop before that lower level has been activated (as can happen on Mandrake 9.2 systems, for instance).

In rare cases, there may also be a problem related to your PC/SC driver. If this happens, you do well to restart that and then use Reattach Shaman Agent. The way to restart the PC/SC driver may differ per token, but it usually is

/sbin/service pcscd stop
/sbin/service pcscd start

These commands should explicitly confirm success or failure; if the first command fails, it is usually a sign that the driver has died before (leading to the problems stated here). It may be that you are instructed to remove some files, which you can usually accomplish with a command like

rm -f /var/run/pcscd.*

Please note that these PC/SC level instructions are dependent on the exact type of driver you are using. Refer to your token's manual for details.
