Perl Ping Loop

Hi All

i have an issue with ping, we are using dhcp and so if the machine has been offline and i ping it, i get " ping: unknown host <hostname>

is there a way i can stick a loop somewhere so it would keep trying when it got the unknown host error and then when the machine came back online just carried out the normal ping command

thanks

Perl Ping Determine Success or Fail

I know how to ping in Perl. That is easy. What I am wondering is if there is a way for Perl to determine whether the ping was successful or not. Or do I need to save the results out and parse the results seperately looking for the #of tries and successful revieves. Thanks. (1 Reply)
