Second question about Microsoft Software Update Service equivalent in linux.

Dears

Microsoft SUS is :
a free patch management tool provided by Microsoft to help network
administrators deploy security patches more easily. In simple terms,
Microsoft SUS is a version of Windows Update that you can run on your
network. Today corporations have to frequently check the Windows Update
site or the Microsoft Security Web site for patches. Then they have to
manually download patches that have been made available since they last
visited the site, test the patches, and then distribute the patches
manually or by using their traditional software-distribution tools.
Instead of each workstation having to connect to the Internet to update
Windows, each workstation connects to the Microsoft SUS Server instead
and updates from there. Microsoft SUS Server alone requires access to
the public Internet as it connects to Windows Update.
Now can anyone tell me if there any equivalent for this in linux.

You could setup your own http/ftp server. On that you mirror one of the
public linux-update servers of SuSe/RedHat/Debian. Actually you need
just to mirror the version which you are using of the distribution of
your choice. Then you configure your linux boxes on your network to use
your own FTP/HTTP server for new package Installations or updates.

Hope that helps
