The entire distribution seems to have ^M (suggesting it came from a
different editor), FYI.
I don't see mention of a table to use in the blocksshd.conf file... does
this presume that the host system isn't using other tables?
Is this being defined by:
my ($exists) = system("$cfg->{pfctl} -t $cfg->{chain} -T show| grep -q
'$IP'"); ^M
$cfg->{chain}
