bug-folk: I have some simple perl scripts that use the most basic functions of the CGI module. I have many scripts that present simple forms to a users to collect basic input and then generate graphs or present requested data from mysql databases. Very basic stuff. These scripts have been run for years in both MS windows and Linux environments. Recently we have begun to implement IPv6 on our campus and I began to make these scripts available from IPv6. Currently I am having some trouble in the following environment: o OS: Windows 2008 server 32bit o HTTPd : IIS7 o Perl : v5.10.1 built for MSWin32-x86-multi-thread Binary build 1006 [291086] provided by ActiveState CGI Handle Common Gateway Interface requests and responses Version: 3.45 Released: 2009-08-14 o Bowser: Firefox 3.68 on Windows 7 host Static pages and some CGI applications (rrdcgi as part of the rrdtools stuff) all work from IPv6 so I think the security and modular stuff from IIS7 are all OK w/r IPv6. What I think is happening is that the "action" as presented in the form output is a problem with the browser when using the IPv6 address format. Not really sure if this is a ActiveState-perl, CGI module problem or poor understanding of script creator (me). Sorry if this is a silly question but any help would be greatly appreciated. -Robert https://[fd9a:2c75:7d0c:1006::10]:8124/tools/dc-port-attribs.pl?switchANDport=lc-6@1/13 <<- works https://%5Bfd9a:2c75:7d0c:1006::10%5D:8121/tools/dc-port-attribs.pl?switchANDport=lc-6@1/13 <<-does not work ### basic script if (param()) { # the form has already been filled out #do stuff here } # the form has already been filled out else { #first time through print h1("data center ethernet device port attributes"); print hr(); print start_form(); print p("Enter the device and port of interest."); print p("use format rtr-jh | rtr-jh-2 | ucc-1 | lc-8 | lc-x \@ card/port | PoX , examples -> rtr-jh-2\@4/5 or lc-8\@Po3"); print p(textfield(-name=>"switchANDport", -default=>'', -size=>30, -maxlength=>40)); print p(submit("submit")); print end_form(), hr(); } #first time through ### basic script form output <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml" lang="en-US" xml:lang="en-US"> <head> <title>Get DC port attributes</title> <meta http-equiv="Content-Type" content="text/html; charset=iso-8859-1" /> </head> <body> <h1>data center ethernet device port attributes</h1><hr /><form method="post" action="https://%5Bfd9a:2c75:7d0c:1006::10%5D:8121/tools/dc-port-attribs.pl" enctype="multipart/form-data"> <p>Enter the device and port of interest.</p><p>use format rtr-jh | rtr-jh-2 | ucc-1 | lc-8 | lc-x @ card/port | PoX , examples -> rtr-jh-2@4/5 or lc-8@Po3</p><p><input type="text" name="switchANDport" size="30" maxlength="40" /></p><p><input type="submit" name="submit" value="submit" /></p></form><hr /> </body> </html> ------------------------------------------------------- Robert Davis Network Engineering Group, ITS University of Iowa (319) 335-5603 voice (319) 335-2951 fax robert-davis@uiowa.edu -------------------------------------------------------

Hello, Thanks for the feedback. However, we don't have the resources to provide general support through the bug tracker. If you aren't sure where the problem is, I recommend asking in a support forum, perhaps on http://www.perlmonks.org/ You'll know you have found a bug in CGI.pm if you can write an automated test that fails when you run it. Look in the t/ directory of the distribution for examples. In a case like this, we would like to see references to appropriate RFCs for IPv6 to confirm exactly what the spec is for how we should be behaving. For now I'm marking this bug as "stalled". If a test case is provided, it can be re-opened. Otherwise, it will be eventually be closed. Mark On Mon Aug 09 15:30:47 2010, robert-davis@uiowa.edu wrote: Show quoted text
