Re^2: How to handle Net::Address::IP::Local'->public when we are not connected to internet

Yes it gives some UDP socket connection couldnt created.. type of error. I dont have that in pc here. I saw in my school this morning. But error was linke some .. UDP socket cudnt create.. So how to handle it . I t gives this error because there is no internet access and even then i am trying to get IP , so no connection i guess thats why..

But how i can handle it ? Because if i print it like this :

print "adress is : 'Net::Address::IP::Local'->public";
[download]

Then it just print:

adress is :
[download]

Now it even do not print 0 or null so that i could habdle it like this if($adress=null) {do this} How to handle ?

Try the same with eval. Here is the code, I have added eval part `use strict; use warnings; use Net::Address::IP::Local; print ReturnIpAddress(); sub ReturnIpAddress { select STDOUT; eval{ $address = 'Net::Address::IP::Local'->public ; ## Rece +iving the current IP ## }; if ($@) { print "$@"; return '192.80.160.16'; ##If No IP address received th +en return a static IP of order "192....." } else { return $address; } }` [download] *All is well*	[reply] [d/l]

Same error : `Unable to create UDP socket: A socket operation was attempted to an un +reachable network. at C:/Perl/site/lib/Net/Address/IP/Local.pm line 166. 192.80.160.16` [download]	[reply] [d/l]

No, it is no longer a fatal error. The program just does what you asked it to do: it prints the content of $@. And then it continues and prints your static IP address, which is enough to prove that the program does not die because of the socket exception. Je suis Charlie.	[reply]

If you’re really doing this, and it’s not just a typo, it’s not what you think. Package and object stuff does not work as interpolated strings. Well, not without trickery. This– `print "adress is : 'Net::Address::IP::Local'->public";` –will print this– `adress is : 'Net::Address::IP::Local'->public`	[reply] [d/l] [select]
