Run URL in Perl script 1

[blarneyme]

Running Dynamic DNS and having problems with zoneclient.py and also with ddclient because I can't install some needed modules.

Therefore I am updating the site using the url which works fine, but I want to put it in cron. So my question is how do you execute a URL from a script so it will update the IP if the dynamic IP changes?

I've tried this but not sure it really runs it:

#!/usr/bin/perl 

use LWP::Simple; 

my $url = '[URL unfurl="true"]http://dynamicdns-park-your-domain.com/update?host=yadda&domain=example.com&password=123456abcdef';[/URL] 
my $content = get $url; 

print $content;

What is in $content after you run it?

It returns nothing.

Probably not running then, as you say - try something like this.

my $content = get $url || die "get didn't run:\n$!\n"

$! is the standard place for an error code or string - have a look in the LWP docs if that doesn't work.

does it really have to be perl doing this?

maybe it would be simpler to just use wget. i'd be surprised if it wasn't installed.

since cron is taking care of this, i figure you don't have much need for the actual content returned from calling the url.

i'd just have cron execute:

wget -O - '[URL unfurl="true"]http://dynamicdns-park-your-domain.com/update?host=yadda&domain=example.com&password=123456abcdef'[/URL] >>/dev/null

the "-O -" makes wget print output to stdout which is redirected to /dev/null. of course you could also use "-O myOutfile.htm".

in case it has to be perl und you don't mind using wget, you could also do

my $content = `wget -O - '[URL unfurl="true"]http://dynamicdns-park-your-domain.com/update?host=yadda&domain=example.com&password=123456abcdef'`;[/URL]

not tested, but you get the idea. good luck
