CVS not working !

Hi, I have a CVS account on cvs.fedora.redhat.com:/cvs/docs . Earlier i used to work with the docs-common module. Today i tried to checkout the same module but it gave me the "REMOTE HOST IDENTIFICATION CHANGED" error. Then i removed the entry for cvs.fedora.redhat.com from ~/.ssh/known_hosts file. Then again i tried to checkout the same module and i got "permission denied" error. Here is the output : ============ [ankit@ankit ~]$ export CVSROOT=:ext:ankitp@cvs.fedora.redhat.com:/cvs/docs [ankit@ankit ~]$ export CVS_RSH=ssh [ankit@ankit ~]$ cvs co docs-common For more information on using the Fedora source code repositories, please visit http://fedoraproject.org/wiki/UsingCvs Permission denied (publickey,keyboard-interactive). cvs [checkout aborted]: end of file from server (consult above messages if any) [ankit@ankit ~]$ ============ Can somebody please help me to resolve this issue?
