Shell Programming and Scripting

thanks pludi,
yes, zypper search telnet has given me the output as:
package telnet-server ....
has installed in my OS.

But when i tried:
zypper install telnet-server
i got error as:
Please insert media [Failed to mount cd:///?devices=.......: No medium found.

so,how would i install telnet ??? and what insert media is it asking?
Is it asking the package CD? if so,then Why it is asking CD if it is already in the storage.

'zypper search' searches through a list of packages that the system knows of. This includes both installed an not installed packages. Just because a package turns up on your search doesn't mean it's locally available on your system, but only that zypper knows where to find it. As long as there isn't an 'i' in the first column, it isn't installed.

'zypper install' then tries to fetch the package, either from the installation media or a network repository, local or global. An example for a global repository would be the OpenSuSE/Novell update server.

As long as you don't add a network repository, zypper will always try to install packages from the installation media. This means that you're limited to what's on CD, and are cut off from security updates (which are always highly recommended).

how would i add a network repository ??

also there is no 'i' in the first column for telnet-server.so,what is the altimate solution to use telnet??

If you've got SuSE Enterprise Linux (SLES), go ask Novell how to keep your system up-to-date.
If it's OpenSuSE, do this

Code:

# zypper ar -t yast2 http://download.opensuse.org/distribution/<version>/repo/oss/ <alias>
# zypper refresh

where <version> is your version of SuSE (10.2/10.3/11.0/...) and <alias> is a shortname for you to define. Afterwards a simple 'zypper in telnet-server' should be enough.

thanks pludi,
I have OpenSuSE,and thanks for the help.
