About project

Ssh (Secure Shell) is a program for logging into a remote machine and for
executing commands in a remote machine. It is intended to replace
rlogin and rsh, and provide secure encrypted communications between
two untrusted hosts over an insecure network. X11 connections and
arbitrary TCP/IP ports can also be forwarded over the secure channel.

OpenSSH is OpenBSD's rework of the last free version of SSH, bringing it
up to date in terms of security and features, as well as removing all
patented algorithms to separate libraries (OpenSSL).

This package includes the core files necessary for both the OpenSSH
client and server. To make this package useful, you should also
install openssh-clients, openssh-server, or both.

You can build openssh with some conditional build swithes;

(ie. use with rpm --rebuild):

--with[out] skey smartcard support (disabled)
--with[out] krb5 kerberos support (enabled)
--with[out] watchdog watchdog support (disabled)
--with[out] x11askpass X11 ask pass support (enabled)
--with[out] gnomeaskpass Gnome ask pass support (enabled)
--with[out] ldap OpenLDAP support (disabled)
--with[out] sftpcontrol sftp file control support (disabled)
--with[out] hpn HPN ssh/scp support (disabled)
--with[out] audit audit support (disabled)
--with[out] libedit libedit support in sftp (enabled)
