Nmap, tty and Perl
Hi,
I am trying to get nmap to be a bit more friendly by wrapping it
inside a perl script that will cause it to spit out a status by
sending it a character:
==
#!/usr/bin/perl
use IPC::Open3;
use POSIX :sys_wait_h;
use FileHandle;
$| = 1;
my $nmap = /usr/bin/nmap;
my @ips = ('192.168.1.*');
my $cmdline = $nmap $args -v -v -v -sT -p 1-65535 -oX - .(join ' ',@ips);
print cmdline: $cmdline\n;
my ($readfh, $writefh, $errorfh) = (FileHandle-new(),
FileHandle-new(), FileHandle-new());
my $pid = 0;
$pid = open3($writefh, $readfh, $errorfh, $cmdline) || die Can't open
pipe to $cmdline: $!\n;
while($readfh) {
print $_;
print $writefh A;
}
print STDERR done\n;
==
nmap will give out a progress if keyWasPressed is detected the code
for this is found inside nmap_tty.cc which basically does:
if ((c = tty_getchar()) = 0) {
For some reason the above code doesn't do it, is it because its not
being sent via tty? if so is there a way to fool it?

Re: Nmap, tty and Perl
Gabor, Those two are great packages, but they don't get a more frequent progressbar than that which is spit out by Nmap, which is problematic if you want to show it more interactively to the user. BTW: 1) the first one has several bugs, for example it gets stuck as it waits for the IO which never comes :D - but it is easy to fix... just remove the $error join which is found in the Parser 2) the second one is synchronic only (doesn't support asynchronic), which is problematic On Thu, Jun 25, 2009 at 12:10 PM, Gabor Szaboszab...@gmail.com wrote: On Thu, Jun 25, 2009 at 10:59 AM, Noam Rathausno...@beyondsecurity.com wrote: Hi, I am trying to get nmap to be a bit more friendly by wrapping it inside a perl script that will cause it to spit out a status by sending it a character: I don't know much about nmap but have you looked at either of the following modules ? http://search.cpan.org/dist/Nmap-Scanner/ http://search.cpan.org/dist/Nmap-Parser/ Gabor http://www.perl.org.il/ ___ Linux-il mailing list Linux-il@cs.huji.ac.il http://mailman.cs.huji.ac.il/mailman/listinfo/linux-il

Hi Noam!
A few comments on your Perl code.

1. You should add use strict; and use warnings;. They prevent many common
errors.
2. The FileHandle module was largely superseded by IO::File, IO::Socket, etc.
You should use them instead.

my $nmap = /usr/bin/nmap;

my $cmdline = $nmap $args -v -v -v -sT -p 1-65535 -oX - .(join '

Where is $args declared and defined?
Also consider using http://search.cpan.org/dist/String-ShellQuote/ .
my ($readfh, $writefh, $errorfh) = (FileHandle-new(),
FileHandle-new(), FileHandle-new());
This can be more elegantly written as map { IO::Handle-new() } (1 .. 3);
my $pid = 0;
$pid = open3($writefh, $readfh, $errorfh, $cmdline) || die Can't open
pipe to $cmdline: $!\n;
while($readfh) {

Perhaps read one character at a time here? (Or set $/ ?)

Re: Setting NFS server on Fedora Core 9
Try to see that RPC is working properly the shares are really exported: from the server run: rpcinfo -p 0 (shows RPC) - check for NFS entries showmount -e 0 - check that you see the shares you expect from the client run the same commands just with the IP address of the server instead of 0 sometimes /var/log/messages on the server can be useful as well, for instance when you have permissions problems because of bad DNS configurations.

Actually, it is the other way around. Some build issues caused MSVC to
generate much smaller (and probably mal-functioning) binaries. I fixed several
problems now that caused it to fail in the 2.32.0 release. However, with a
previous release, the build did not fail (but generated the small binaries).
The NEWS file for 2.32.1 reads:
{
Version 2.32.1: (25-Jun-2009)
-
1. Added a #define BUILDING_DLL 1 so fcs_dllexport.h will work fine on
Microsoft Visual C++.
2. Normalised the DLLEXPORT modifiers.
3. Some fixes to the CMake build system:
- CHECK_C_COMPILER_FLAG now uses a different variable for each flag,
since the variable was cached.
- tcmalloc is now truly optional.
4. Moved the declaration of the strncasecmp(a,b,c) macro for WIN32 systems
to before its first use.
5. All of this was done to fix many build/compilation problems.
}
