Can't connect to CVS

Hi all, I'm having difficulty connecting to CVS: Permission denied. I last connected successfully a month or so ago but can't get in now... I have resubmitted my RSA public key to FAS and re-downloaded all the certificates but no joy. Here's an example session: $ export CVSROOT=:ext:cnolan@cvs.rpmfusion.org:/cvs/nonfree $ export CVS_RSH=ssh $ cvs co common Permission denied (publickey,gssapi-with-mic). cvs [checkout aborted]: end of file from server (consult above messages if any) $ cvs -t co common -> main loop with CVSROOT=:ext:cnolan@cvs.rpmfusion.org:/cvs/nonfree -> safe_location( where=(null) ) -> Starting server: ssh -l cnolan cvs.rpmfusion.org cvs server Permission denied (publickey,gssapi-with-mic). cvs [checkout aborted]: end of file from server (consult above messages if any) -> Lock_Cleanup() And the debug output from "ssh -vvv -l cnolan cvs.rpmfusion.org cvs server" is here: http://dpaste.com/101652/ I'm pretty sure that the noise between lines 9 and 38 is a red-herring. The real problem seems to be that the server doesn't accept my key. I can successfully connect to other servers using publickey auth from the same machine. Any help? Thanks Chris
