NAME
kf -- securely forward tickets SYNOPSIS
kf [-p port | --port=port] [-l login | --login=login] [-c ccache | --ccache=ccache] [-F | --forwardable] [-G | --no-forwardable] [-h | --help] [--version] host ... DESCRIPTION
The kf program forwards tickets to a remote host through an authenticated and encrypted stream. Options supported are: -p port, --port=port port to connect to -l login, --login=login remote login name -c ccache, --ccache=ccache remote cred cache -F, --forwardable forward forwardable credentials -G, --no-forwardable do not forward forwardable credentials -h, --help --version kf is useful when you do not want to enter your password on a remote host but want to have your tickets one for example AFS. In order for kf to work you will need to acquire your initial ticket with forwardable flag, i.e. kinit --forwardable. telnet is able to forward tickets by itself. SEE ALSO
