Now I have the following problem.
I need to count how many times certain traffic comes from an IP address. I'm
using perl hashes for that where the IP address is the key and the counter is
the value. Fine so far. Then, I need to report that and for that I'm doing the
following inside eval:
while ( my ($key, $val) each %%my_hash) {
print (IP: $key, counter: $val);
}
The counter values print fine but all keys print some gibberish instead of the
IP addresses.
Any suggestions?
BTW: I'm counting the events using eval %o (++$my_hash{$3}); where $3 has the
IP value that I need to record.
Thanks,
Rafael
