The OpenSSH packages provide the OpenSSH set of network
connectivity tools for logging into and executing commands on a
remote machine. OpenSSH tools encrypt all traffic (including
passwords), so you can avoid eavesdropping, connection hijacking,
and other attacks on the communications between your machine and
the remote machine.
The openssh package includes core files
needed by both the OpenSSH client programs and the OpenSSH server.
The openssh package also contains
scp, a secure replacement for
rcp (for securely copying files between machines).
The openssh-askpass package supports the
display of a dialog window which prompts for a password during use
of the OpenSSH agent.
The openssh-askpass-gnome package can be used
in conjunction with the GNOME desktop environment to display a
graphical dialog window when OpenSSH programs prompt for a
password. If you are running GNOME and using OpenSSH utilities,
you should install this package.
The openssh-server package contains the
sshd secure shell daemon and related files. The
secure shell daemon is the server side of the OpenSSH suite and
must be installed on your host to allow SSH clients to
connect to your host.
The openssh-clients package contains the
client programs needed to make encrypted connections to SSH
servers, including the following: ssh, a secure
replacement for rsh; sftp, a
secure replacement for ftp (for transferring
files between machines); and slogin, a secure
replacement for rlogin (for remote login) and
telnet (for communicating with another host via
the Telnet protocol).
