      Ok, someone correct me if I am wrong please, but I believe that when you originally configured the CPAN interface (upon first run), there was an option within the multitude of questions you are asked regarding whether or not you are using a Proxy server. If that was answered "no", then it will not know how to use the proxy and you will have to re-run the CPAN setup again to setup the proxy piece.

      Here are the instructions for starting the reconfiguration :

      Start the CPAN interface with:

      perl -MCPAN -e shell

      then, once at the CPAN prompt, type:

      cpan> o conf init

      From there, it is up to you to walk through the configuration.

      Regards,

      Jeff

              Wow, not sure. If that username and passwd work for you normally, and the address of the proxy server(s) is correct, then that should work, IMHO.

              Jeff

                  dear friends, is there any way to get perl modules installed without using cpan.

                  please suggest,

                  thanks

                      You certainly can! All you need to do is read the perlmodinstall page to figure out how.

                          But I would encourage you strongly to use CPAN.

                              thanks a lot frnds. i resolved my problem by using ntlmaps for proxy authentication.

                              now i am facing a problem using CVS to fetch marc-record

                              the error i am encountering is the following

                              ":2401 connection timed out"

                              give me some idea on how to do CVS through a proxy.

                              regards
                              chandru
