Editing CPAN.pm

tame1 has asked for the wisdom of the Perl Monks concerning the following question:

I find myself in a quandry. CPAN's Config.pm shows the correct
http proxy. However, my proxy here requires a username and password.

When I write my own, I use the following lines:

$ua->proxy(['http'],'http://xxxxxx.nb.ford.com:83');
$req->proxy_authorization_basic("username","password");
my $res = $ua->request($req);
[download]

My problem is that in walking through CPAN.pm, I cannot tell
where to edit to make it use that kind of proxy authorization.

Can anyone help with this? What does this little button do . .<Click>; "USER HAS SIGNED OFF FOR THE DAY"

Looking around, I found the CPAN readme. It looks as if your proxy requires a login you'll have to configure your individual services to support that. The example given in the readme is this: `If you can go through your firewall with e.g. lynx, presumably with a +command such as /usr/local/bin/lynx -pscott:tiger then you would configure CPAN.pm with the command conf lynx "/usr/local/bin/lynx -pscott:tiger"` [download] Obviously, you'd have to set up ftp similarly. Of course, YMMV. Guildenstern Negaterd character class uber alles!	[reply] [d/l]

Another option, if running nix, would be to set the proxy environment. For a Debian box behind an MS proxy, add the following to `$home/.bashrc` and/or `$home/.bash_profile` as appropriate. `export http_proxy="http://NTdomain\user:password@proxy.DNSdomain:portn +umber"` [download] Thanks to tilly for showing me this a while back. Well, the "export http_proxy" part anyway, not the MSproxy-specific syntax. Update:* I think this will eliminate the need to config lynx, wget, etc. separately. cheers, Don striving for Perl Adept (it's pronounced "why-bick")	[reply] [d/l]

I had a similar problem where I work. The solution is not to fix CPAN, but to fix the underlying transport mechanisms to know about the authenticated proxy. LWP knows how these work, so it was just a matter of correctly configuring LWP for my machine, which is something that should have been done when it was first installed. Things now work like a charm, and any other script or module that makes use of LWP's functions now automatically sees through the authenticated proxy.	[reply]

Solution was found, but it was unwieldy. Each program used by CPAN, such as wget, lynx, etc., has it's own way to talk to a proxy. I had to change each program config in CPAN's Config.pm. For example, wget can use `--proxy-user=myid --proxy-passwd=mypass` The fun part of that one is that you will NOT find it in the man page for wget. You will only find it doing wget --help. For those who need this in the future, I hope this helps. What does this little button do . .`<Click>`; "USER HAS SIGNED OFF FOR THE DAY"	[reply] [d/l] [select]

Just update your proxy url to include your username and password, like this: `$ua->proxy(['http'],'http://user:pass@xxxxxx.nb.ford.com:83');` [download]	[reply] [d/l]
