Description:
------------
Version 2.4 of Net_Ping throws a pear error with message "Backend not supported"
I believe this is down to the change in implementation of get_class_methods() in PHP5 - the strings returned are case-sensitive. This causes the Net_Ping_Result::_prepareParseResult() to fail, as "_parseresultlinux" doesn't exist in the array of class methods.
Suggest
return in_array('_parseresult'.$sysname, $parse_methods);
is changed to
return in_array('_parseResult'.$sysname, $parse_methods);
in Net_Ping_Result::_prepareParseResult()
Reproduce code:
---------------
require_once('Net/Ping.php');
$p = Net_Ping::factory();
$res = $p->ping('172.0.0.10');
if( PEAR::isError($res) ) {
echo $res->getMessage();
}
Expected result:
----------------
No error message
Actual result:
--------------
"Backend not Supported"

oops. Of course:
return in_array('_parseResult'.$sysname, $parse_methods);
will break php4...

This fix for #2314 can also be applied to the NET_Traceroute package as it is plagued by the same bug.
The _prepareParseResult function of the Net_Traceroute_Result Container Class has the same issue and failed for me on win 2000 and XP when using the sample:
Hope this helps

Thanks for posting the fix. I have been beating my head against my desk trying to figure out the problem.
