Hi, I'm trying this on my own on a Centos box but did not have much luck. If anyone else has accomplished this, it would be great if they could share. Having one time passwords on linux would be a great solution for accessing your box from insecure places! Here is the guide I've been following. http://www.freeauth.org/site/wiki/One Time Passwords on Linux Will try it on Fedora 9 when I get home, and post a Howto myself if I'm successful. Also if there are other OTP solutions I could look at, please let me know.
