hi,
I have installed rdesktop 1.6 with smart card support.I have a

usb smart card reader which will accept a smart card for login
the remote client.
Here is scenario,
I have plug in the usb smart card reader and invoke pcscd daemon which recognized the smart card.Now i invoke the rdesktop
with scard option it recognized the smart card.But when i unplug
the usb smart card reader and plug it again(while rdesktop is running) it(rdesktop) does not recognized the smart card.This process work perfectly in Windows but in Linux it does not works.
So can any body help me.

1. start pcscd daemon
/etc/init.d/pcscd restart

2. Get the smart card reader name and number, this command will also make sure that you computer is able to communicate with smart card reader and smart card too.
