OK - I have fixed this error. The actual issue I want to solve is a core
dump. The following occurs....
I have recently written 3 scripts to...
script 1. write raw ICMP packets to an interface
script 2. sniff for them
script 3. act on non-response/response/RTT etc etc (i.e. the boss)
The sniffer script uses the following modules....
Net::Pcap;
NetPacket::Ethernet;
NetPacket::IP;
IPC::Shareable;
The scripts work well on my Gentoo distribution but on Solaris I get a
core dump when I try to use ..
$src_IP = NetPacket::IP->decode($rawpkt)->{src_ip};
The error actually comes from tie-ing the shared memory at the beginning
of the script. If I comment out the tie $var declarations,
NetPacket::IP->decode($rawpkt)->{src_ip} works well.
So it seems to be a clash between IPC::Shareable and NetPacket::IP.
Anyone seen this before.
(Apologies for the earlier 'p is not of type pcap_tPtr' confusion. I had
two weeks off and my brain is mush!!)
Thanks
Andy
