That should be $file in your error message.

Why don't you chomp $node here? It will have a newline at the end.
while (my $node = ) {
chomp $node;
system "script1 -r $db -7 $node -v 9";

Is there some trick to this? use Win32::Console; $con = Win32::Console->new(STD_INPUT_HANDLE); @event = $con->PeekInput(); $tmp = chr($event[5]); print "\n The character typed was: $tmp \n"; If I use Input() instead of PeekInput() it works fine and the docs say that it is suposed to work the same as input, but does not remove input from the keyboard buffer.

RE: win32 console input problem
Thank you. This worked. I was incorrectly figuring the breakdown of the array. Next question, isn't peekinput supposed to work the same way. The program runs without any error, but the array is not populated with peekinput.

Maybe it comes in the statement before that:
$nodename = ;
$iaddr = gethostbyname($nodename);
($a,$b,$c,$d) = unpack('C4',$iaddr);
$ipaddress = "$a.$b.$c.$d";
print $ipaddress;
I have debugged this numerous times and I can't seem to understand why gethostbyname
does not return anything. I have tried with both the hostname and the
hostname.foo.com notation and it does not work.
It does work when I replace $nodename with 'node.foo.com' but I can't get the imputed
variable to work?
Thanks,
Nate.

gethostbyname and getnetbyname
Thank you for the help earlier, but I am still having a problem.
1) I can get gethostbyname to work in this format: gethostbyname('node.foo.com'). I
need it to work in the following format: gethostbyname($nodename). Is this not set
up for that?
2) I tried to alternatively use getnetbyname, but I don't think that it is loaded into
the standard distrabution.
I bet it has something to do with the fact that I am trying to do this with Active
Perl on NT.
Thank for the help ahead of time.

Parsing syscall input.
I am trying to make a feable attempt at parsing a nslookup call. All I actually want
is the IP address. So I figured I would do the following:
$ticker = 0;
foreach $_ (`nslookup $nodename`) {
$_ = $out[$ticker];
$ticker++;
}
print $out[0];
I am getting a uninitalized error for $out[0]. Three questions:
1) What am I doing wrong with this? I am not sure why this is not working.
2) I orginally thought that $_ was a array value and I could just do a "$_ = @foo". I
have found that I am mistaken. Is there any way to get the output into an array from
by line of input?
3) General suggestions on an easier way to do this. Is there an actual function that
will do an nslookup or get the ip address of a nodename?
Thanks.
