Perl, Net::Ping WON'T WORK!!!!!

Net::Ping WON'T WORK!!!!!

Author	Message
Peter J Ratne #1 / 5	Net::Ping WON'T WORK!!!!! I've tried to use Net::Ping in my programs, but I can't seem to get it to work right! For some reason, no matter what protocol I use, the server never responds (yes, I've tried MANY different servers) . I am using the sample script given in the module itself, not one of my own design, so there's no reason why it shouldn't work. I tried running it on both MacPerl and Unix. On MacPerl, no response from server, on Unix, it gives an error regarding Socket.pm and how some arguement should have the value 16 rather than 0. If anyone has had success with this module, I'd greatly appreciate seeing the source or getting some input as to how to get it to work.

Alex Davie #2 / 5	Net::Ping WON'T WORK!!!!! Peter, I've never had any problems with this module... i presume from your mention of protocols that you are using the most recent version of Net::Ping. Can you not just use the (old) pingecho method...? Some thing like this should work fine: use Net::Ping; my $node = 'xyz'; if (pingecho($node, 2)) { print "$node is responding\n"; Quote: } else { print "$node is NOT responding...\n"; Quote: } What was the exact error message you were getting, also which version of perl are you running? alex. _________________________________________________________________________ Texas Instruments Limited, 800 Pavillion Drive, Tel (work): 01604 663450 Brackmills Industrial Estate, (home): 01604 764961 Northampton, NN4 7YL.

Any help would be greatly appreciated. >Here is my short script: >$timeout)) { print "$hosts is alive\n"; }else{ print "$hosts is down\n"; >open MAIL, '\|mail -s "WARNING, system is not responding" matt'; print MAIL >"$hosts is down"; close MAIL; }; }; pingecho uses tcp rather than icmp, so you're relying on a different mechanism. To see if the machineis responding on the tcp echo port you might try telnet firebird echo and if you're connected it should echo data back at you, if you don't get connected or it just sinks your data then pingecho will think the machine is down. To use icmp you need to read the Net::Ping docs and be running as root to have a sporting chance.
