in reply to Re: Problem with Net::FTP
in thread Problem with Net::FTP

Thanks tirwhan for explanation,
Just wondering whether there is any way to check, whatype of proxy my institute is using?? Exactly same problem I am facing in configuring my CPAN.pm as well. There it seems to connect to ftp.cpan but then fails everytime. And one of the error messages it shows complain about user id and password. Now strange thing is, there is none. I can browse the net with any password. Also what do you mean by manual ftp??Do you mean I should try to ftp to some machine outside the campus?? or to cpan?? if cpan than shouln't I know IP address for cpan server
For my firefox browser setting; HTTP, SSL, FTP , GOPHER are given same proxies (XXXX) (and port 3128) but SOCKS_host has been left blank. Does this gives any clue???
Now as you understand my level of comfortability with these lingo (ftp/proxy/firewall) could you pl direct me to some online documentation. I tried a few times to get a feel of these things but often found documents hard to understand.
I admire you patient. Thank you for all your help.

    Yes, ask the resident system administrator :-). S/he should also be able to give you tips on how to configure your FTP connection setup.

    Also what do you mean by manual ftp?
    I meant you should try connecting with the command line "ftp" client (and I'm assuming you have that at your disposal, if you're on Windows this may not be the case, I have no idea), which allows you to set options like proxy and mode on the command line, thus allowing for easy testing of the requirements.

    For my firefox browser setting; HTTP, SSL, FTP , GOPHER are given same proxies (XXXX) (and port 3128) but SOCKS_host has been left blank. Does this gives any clue???

    This does seem to indicate that your institute runs an FTP proxy on that machine, and your code (with the change I made) should work. Have you tried turning on debugging, as rpanman suggested? If so, what's the output?

    could you pl direct me to some online documentation

    Just type "FTP firewall proxy" into Google and you'll find loads of documentation on the subject. The wikipedia entry on FTP might be another place to start


    All dogma is stupid.
      Yes tirwhan,
      I tried running it with rpanman's suggestion and pasted the message in reply to his node. Just to inform you, I am working on Linux OS.

        Right. You also need to set the proxy port (since it appears to use the common HTTP proxy port), so try changing that to

        my $ftp=Net::FTP->new(Host => "ftp.cpan.org", Firewall => "XXXX:3128")

        All dogma is stupid.
