socks - Perl Socket Connection Check -

-

i've been trying debug perl issue awhile had made no head way. i'm trying determain if connection socks4/5 connection.

# ./pctest.pl name "main::junk" used once: possible typo @ ./pctest.pl line 60. name "main::empty" used once: possible typo @ ./pctest.pl line 60. io::socket::inet: bad hostname 'c1(x'   ...propagated @ ./pctest.pl line 52.

i've had error (before added or die @$; @ end):

can't use undefined value symbol reference @ ./pctest.pl line 56.

.

...   $look = io::socket::inet->new( peeraddr => $_, proto => 'tcp', timeout => 5 ) or die @$;              $sock4 = pack( "ccs", 4, 1, 80 );              print $look $sock4;              read( $look, $recv, 10 );              ( $empty, $granted, $junk ) = unpack( "c c c6", $recv );              if( $granted == 0x5a )             {                     print " yes\n";             }             else             {                     print " no\n";             } ...

there's typo. @$ should $@.

to rid of "possible typo" messages , since $empty , $junk seem unused in code, write:

my @result = unpack("c c c6", $recv);  if ($result[1] == 0x5a) { # ... }
