Re: Determine ip address/hostname of requesting host

Hi davidj, As ikegami recommends, use CGI.

Personally, I like the remote_host() command, (which you can get from reading the CGI documentation):

use strict;
use warnings;

use CGI qw/:standard/;
use CGI::Carp qw(fatalsToBrowser);

my $ipaddr = remote_host();
                                               
# Now log the address $ipaddr ...

s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/

use CGI::Carp qw(fatalsToBrowser); One comment: Don't use `fatalsToBrowser` in a production environment. It could potentially provide an information leak. In production CGI::Carp is going to log to your web server's log files any spew that comes forth. The user just sees something went wrong without knowing what. Peter L.

blue_cowdawg, Don't use `fatalsToBrowser` in a production environment. Thanks; that is a good tip. To date, all of my own CGI experience has been limited to a local network, where the consumers of my work are mostly other developers, so it's seemed natural to provide as much detail as possible. But I've had in the back of my mind that it probably isn't what you'd want to do in a larger (ie. visible-to-the-outside) context. I'm glad you gave that advice, which I'll remember in case I ever do happen to develop for a "production environment". s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/	[reply] [d/l]
