Shows you what you have.

Removes the incorrect URL you have stored.

Adds an example URL. If you don't see a line similar to this:

configuraiton changes aren't automatically being saved. Either do:

To save the changes you made, or change your configraution to commit changes automatically. I'll leave this as an exercise for you, see o conf options and CPAN.

Thanks marto, it has helped me a lot.

Hi marto, can you help me on my updated question please?

There's also an interactive way in the shell, probably something with o conf urllist, but I can never quite remember the syntax, and you need to remember to o conf commit at the end.

"and you need to remember to o conf commit at the end."

I think this depends on your Perl version. Strawberry v5.12.3 which I have on my Windows laptop does it automatically, our clients aging 5.8.8 (I know, I know, we're working on it) installed on Solaris doesn't.

Update: s/install/installed/

"My apologies if I am asking stupid question. Due to some reasons my server is restricted from accessing the said URL :-(. Now I just want to install Net::SFTP module, I wonder if I can download the tar.gz file on my laptop from CPAN site and upload it to my Linux server. And then can install it? Is it possible to use CPAN to install this standalone tar.gz file ? I would be grateful if you could direct me to some tutorial which could guide me on this part. The CPAN tutorial on Does Not tell us, what to do if the server cannot access repository."

Which URL are you trying? Have you tried another mirror? Have you contacted your network/system administrators about this? If you can access it from your laptop but not the linux server, and if they're on the same network the sysadmin may be willing to grant access to this.

When installing modules you'll often need to satisfy dependancies. If for one reason or another the powers that be don't want to alter anything with the server/network config then another option would be to create a mirror of cpan on your laptop. minicpan does this for you. You can then transfer this from your laptop to the linux server and configure cpan to use this rather than a remote server. Please note I'd advise talking to system/network admins before doing any of this. It may be against a policy or something, and you don't want to get in trouble.

If you don't mind downloading all the dependancies, you can install modules via the traditional method

perl Makefile.PL
make
make test
make install
