If you are not a root user, or the code is not run by the web server as a
user with high enough privileges, it may not be able to open a socket on the
system...
Mind you, apache does not run as root, so that could be a problem...

When you say that on the web it does not work, is that on another server? Or
the same box?

Thanx Bill,
i made a test with e shell script in perl to testing the ftp server via a
socket connektion: ist very quick and clean ( my opinion ):
------------------------------------------------------------ script:
#/ drives
$drivelist = "<table border=\"0\">";
foreach(keys %FTPDRIVES)
{
($ftp_name, $ftp_description, $ftp_server, $ftp_login,
$ftp_pass,
$ftp_mode, $ftp_dir)=split(/\t/, $FTPDRIVES{$_});
#// ping drive
if(open_TCP(F, "$ftp_server", 21) == undef)
{ #--> ping error
$drivelist .= "ERROR<tr><td><a
href=\"javascript:openFTP(".$_.");\"><img src=
\"$pic_dir"."/ftperror.gif\"
border=\"0\"></a></td></tr><tr><td>$ftp_name</td></tr>";
}
else
{ #--> ping ok
$drivelist .= "<tr><td><a
href=\"javascript:openFTP(".$_.");\"><img
src=\"$pic_dir"."/ftpok.gif\"
border=\"0\"></a></td></tr><tr><td>$ftp_name</td></tr>";
}
}
$drivelist .= "</table>";
$deskTEPL =~ s/<!--drives-->/$drivelist/g;
sub open_TCP
{
my($FS, $dest, $port) = @_;
my $proto = getprotobyname('tcp');
socket($FS, PF_INET, SOCK_STREAM, $proto);
my $sin = sockaddr_in($port, inet_aton($dest));
connect($FS, $sin) || return undef;
my $old_fh = select($FS);
$| = 1;
select($old_fh);
1;
}
------------------------------------------------------------
So, if a ftp server is on, the script printas out a ok sign, or of not a
other sign !
on the Dos.Shel it works fine !!! But in the Web, it always prints the ok,
sign ! ! ! pretty shitty !
you thougt ?

It depends on what you want to check -
Ping / Net Ping will tell you if the machine itself is on, but not if the
FTP service is active...
DNS - I am not sure what you mean with this one...
Login Test - This will tell you if the FTP service is responding. I am not
sure I would actually have it login, but you should establish a connection
without sending any username / password. I am not sure Net::FTP will let
you do this, but a telnet to the FTP port should tell you.

Hi folks,
what do you think is the fastest way to check out if a ftp server available
or not ? ping ? net::ping ?? or DNS ?? or a login test ?
