Name        : gsi-openssh
Product     : Fedora 15
Version     : 5.6p1
Release     : 4.fc15
URL         : http://www.openssh.com/portable.html
Summary     : An implementation of the SSH protocol with GSI authentication
Description :
SSH (Secure SHell) is a program for logging into and executing
commands on a remote machine. SSH is intended to replace rlogin and
rsh, and to 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 version of the last free version of SSH, bringing
it up to date in terms of security and features.

This version of OpenSSH has been modified to support GSI authentication.

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

Update Information:

Update to Globus Toolkit 5.2

Many of the changes implemented by upstream in this release, such as the removal of the flavour tags in the library names and the support for standard installation paths, were already present in the Fedora packages of earlier releases using patches. This update is backwards compatible and does not introduce any soname bumps.

The most important change is the handling of threads. In earlier releases the threading model was chosen at compilation time, and the model used by the libraries in Fedora and EPEL was using pthreads. In this release the threading model is instead chosen at runime, either by using API calls or by setting environment variables. The default model in the new release is the forking model, but also the pthread model is available.

In order to preserve the behaviour of applications linked to previous versions, versioned symbols have been introduced so that the new libraries will switch to the pthread threading model automatically when used by applications that were linked to earlier versions.
