[Help] About check out package from CVS

[Hao Liu <hliu redhat com>]

Hi,
  I'm running into a problem when I tried to check out package from the repository,
  I followed the steps given in http://fedoraproject.org/wiki/PackageMaintainers/Join#Install_the_Client_Tools, no luck.
  I tried:

  $cvs co package-name

  error messages:

  Permission denied (publickey,keyboard-interactive).
  cvs [checkout aborted]: end of file from server (consult above messages if any)

  were given out.

  Additional info:
  1. rpm -q cvs
     cvs-1.11.22-13.fc9.i386
  2. echo $CVSROOT
     :ext:hliu cvs fedoraproject org:/cvs/package-name
  3. echo $CVS_RSH
     ssh

  Any help will be greatly appreciated, :-)

All the best,
Hao Liu
