Cheers all, Alan, the log I sent was taken from a putty log, so it's likely had some windows tampering. The linux files have only been edited in vi. The information given by Prateek has helped me sort out the pem file issue, but I'm still getting rejected clients with the certificate compatibility warning. Should I be using .key files, or .pem for the ca? Cheers, Andi ________________________________________ From: freeradius-users-bounces+amorris=cardiffmet.ac.uk@lists.freeradius.org [freeradius-users-bounces+amorris=cardiffmet.ac.uk@lists.freeradius.org] on behalf of alan buxey [A.L.M.Buxey@lboro.ac.uk] Sent: 19 July 2012 12:28 To: FreeRadius users mailing list Subject: Re: More certificate trouble hi, your config file also has lots of ^Ms at the end of each line - the sure sign its been touched by a windows box... use 'dos2unix' to clean up your config files alan - List info/subscribe/unsubscribe?
