OpenSSH is a FREE version of the SSH protocol suite of network connectivity tools that increasing numbers of people on the Internet are coming to rely on. Many users of telnet, rlogin, ftp, and other such programs might not realize that their password is transmitted across the Internet unencrypted, but it is. OpenSSH encrypts all traffic (including passwords) to effectively eliminate eavesdropping, connection hijacking, and other network-level attacks. Additionally, OpenSSH provides a myriad of secure tunneling capabilities, as well as a variety of authentication methods.

For updated implementations, see also SSH2 development Library.

This software is distributed in two modes:
  • as compressed package that you have to download and manually install; if prerequisites are required, you will have to manually install them too;
  • as RPM package; you can install it using your favorite rpm package manager, that will take care to download and install both the software and its prerequisites.
Choose the installation mode that you prefer. Please note that not all the versions are available in both the installation modes.

Installation with rpm

This program is installable using the rpm package manager. See below for the install string. Required prerequisites are automatically processed by the package manager and, if needed, downloaded and installed.

Changes since OpenSSH 5.2 ========================= General Bugfixes: * Do not limit home directory paths to 256 characters. bz#1615 * Several minor documentation and correctness fixes. Portable OpenSSH Bugfixes: * This release removes for support for very old versions of Cygwin and for Windows 95/98/ME * Move the deletion of PAM credentials on logout to after the session close. bz#1534 * Make PrintLastLog work on AIX. bz#1595 * Avoid compile errors on FreeBSD from conflicts in glob.h. bz#1634 * Delay dropping of root privileges on AIX so chroot and pam_open_session work correctly. bz#1249 and bz#1567 * Increase client IO buffer on Cygwin to 64K, realising a significant performance improvement. * Roll back bz#1241 (better handling for expired passwords on Tru64). The change broke password logins on some configurations. * Accept ENOSYS as a fallback error when attempting atomic rename(). bz#1535 * Fix passing of variables to recursive make(1) invocations on Solaris. bz#1505 * Skip the tcgetattr call on the pty master on Solaris, since it never succeeds and can hang if large amounts of data is sent to the slave (eg a copy-paste). bz#1528 * Fix detection of krb5-config. bz#1639 * Fix test for server-assigned remote forwarding port for non-root users. bz#1578 * Fix detection of libresolv on OSX 10.6.
