Hello, Well I'm headed out to California for one month to get this stuff ported over to Mac OS for Apple. I will be working full time on pcsc-lite for one month. (Don't worry, it will still be open source/free) I think the strange problems on Redhat might be due to a needed compiler/libs upgrade. Once out there I'm going to get Redhat 6.1 and compare the compiler/libs with Mandrake 6.1 and see if I can't upgrade the Redhat box and see if that make everything work fine. I know for a while there was a nasty memory issue with libdl about a year ago, I don't know if Redhat has added that patch in their distribution or not but I will find out. I will probably release a new smarttools package that works 100% on digital signatures, it supports remote PAM authentication using the RPC mechanism built into pcsc-lite, and a GUI file encryption/decryption utility for KDE. The remote PAM authentication is more a proof of concept that you can call back on the resource manager to perform remote authentication. Security wise, you will have to assure that your card has proper security, ie: channel management, pin, keys. I will be releasing a paper later this month about some smartcard hacks that should be avoided when developing a smartcard infrastructure in a London security journal. By the end of the month pcsc-lite will be Beta/Final.
