Re: Running Apache behind LinkSys Router
Indeed NOT a cgi related question. There is probably more than just the router configuration. Now do this... 1. Check what IP address of the system your website is running on. If it runs on all IPs designated to the system then nothing to worry on that part. 2. Check port forwarding to the IP address and do make sure it is the right port 80 or 8080 or whatever you use, should be configured correctly on the router 3. IMPORTANTLY... check the DNS settings. If your site is accessed internally as foobar.homelinux.com, is it configured on some external DNS to point to the router's IP address that is forwarding it?

Ending a compound statement
Does a compound statement need to end with an else ?
I know -
if (expression) {
statement;
} elsif (expression) {
statement;
}
works but I've never seen a block like that in a book yet. I usually
see something like -
if (expression) {
statement;
} elsif (expression) {
statement;
} else {
statement;
}
I've posted the following code to use as an example. Any critique of
the code in addition to my specific question is welcome:) I just don't
see a reason to stick an else statement on the end of that block.

RE: Ending a compound statement
Hello Kenton,
It depends on what you want to do. There is not really a right way, since
the two series of statements you mention will lead to different results.
(I added numbers to the different parts of your examples, makes them a bit
easier to follow)
if (expression1) {
statement1;
} elsif (expression2) {
statement2;
}
This evaluates expression1, and executes statement1 if true. If expression1
was false, it will evaluate expression2, and if that is true, will execute
statement2.
if (expression1) {
statement1;
} elsif (expression2) {
statement2;
} else {
statement3;
}
This will do the same as the first example, but if expression2 is false,
then it will enter the else and execute statement3. The main difference is
that you provide something to do for both the true and false cases for BOTH
your conditions, whereas in the first example, if expression2 was false it
simply exited and continued down in the file.
Hope this helps,
J-S

Either way is fine. If you leave off the else block and all the conditions
are false, nothing is executed.

Looks fine to me, except that if the last condition fails, the program will
silently end and the user won't know why. Does that matter?

Nice piece of code; clearly starting in the right
general direction. I think I can see why you are
asking about whether or not one should do an 'else'
side of that tree.
So first things first, Do You REALLY want to
know what @ARGV was prior to calling GetOptions?
as a demonstration code:
print started with ARGS:\n;
print : $_ foreach(@ARGV);
print :\n;
my %options;
GetOptions (\%options, version, help);
while ( my ($k,$v) = each %options )
{
print $k - $v\n;
}
print Ended with ARGS:\n;
my @string = @ARGV;
print : $_ foreach(@string);
print :\n;
[jeeves: 9:] ./get_opt_demo.plx -h bob fred --version
started with ARGS:
: -h : bob : fred : --version :
version - 1
help - 1
Ended with ARGS:
: bob : fred :
[jeeves: 10:]
I take us on this misadventure to recommend my traditional
approach of basically Hiding the 'parse command line options'
in function of it's own that will resolve if all the
required things are there, and returning only
what needs to be dealt with, since the code is now Good to Go.
say something on the order of
my ($argv, $options) = parse_cmd_line();
where of course $argv is an array ref and $options is
a hash ref of stuff that will be used in the code.
This way down in that
sub parse_cmd_line
{
...
if ( $options{version} $options{help} )
{
print_version('help'); # tell print_version to call help and
exit
} elsif ( $options{help} or scalar(@ARGV) != 1 )
{
# in the case we ONLY want one argument
help_message();
} elsif ( $options{version})
{
print_version(); # just the version string
}
([EMAIL PROTECTED],\%options);
}
I of course implement your help_message() function with
the ability to take an argument like
sub help_message
{
my ($whiney_msg) = @_;
print $whiney_msg if $whiney_msg;
...
}
Which of course gets me to your
sub get_record {
my ($reg_ex, $file ) = @_;
die needed a regular expression
unless($reg_ex);
$file ||= /etc/dhcpd.conf;
open (DHCPD, $file) || die Can't open $file : $!\n;
$/ = '}'; # paragraph delimiter
while ( DHCPD ) {
if (m/$reg_ex/i) {print $_\n\n};
}
close (DHCPD) || die Error closing /etc/dhcpd $!\n;
}
This way you move towards reading IN the RegEx that
is passed to the function - and can pass in a 'test file'
for the duration of hacking out the test context...
HTH...

Vendor Supplied, Vendor Supported I think is the phrase you were looking for. Ironically, the modules that i did the build and install of show up - eg: libex: 57:] ./find* | head -12 Digest::MD5 HTML-Tree HTML::Parser HTML::Tagset MIME::Base64 Net Net::Telnet Perl URI libwww-perl /usr/local/lib/perl5/5.6.1/File/Spec/Functions.pm /usr/local/lib/perl5/5.6.1/Shell.pm libex: 58:] Those modules that are of course there with the Perl are your friends and mine, the underlying requirements for installing libwww-perl and were installed the old fashion way, from a re-build in the src tree... But over on the stock Suse Linux box, none of the stuff that is in vendor_site shows up in the process. Repeat for Redhat 7.X and 9.X pro and vanilla. So given that the OP had asked about knowing what was on their Linux Box, it is not a complete Leap of Faith to presume that they are working with the 'perl stuff' that delivered onto their box from the Vendor with YAST - since clearly the OP had not done the traditional old school tie of walking their source tree to do the build and install per OS type and CPU architecture to make the cut over from pre perl5.8 to post perl5.8 but I am willing to admit that is a presumption of mine. Without .packlist there's no real way of establishing what useable modules are installed. The best you can do is to list all the 'package' statements in all the .pm files in @INC. A lot of these packages internal to the module and aren't meant to be 'use'd directly. What gets even gigglier in all of this is that at least the Freaks over at Apple 'did the right thing' with their Foundation and PerlObjCBridge bridge elements. But there is also the Irony, that my idiotic dtkp::WebMe which of course does have the obligatory .packlist file in the 'site_perl' section is not found... So clearly there are more than a few issues that will need to be cleaned up in the overall process here. ciao drieux --- -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] http://learn.perl.org/ http://learn.perl.org/first-response
alternating loop
Hello,
been trying to come up with a way, while going through a loop to alternate a
table cell color td/td
IE.
while (..) {
# To alternate a td cell color for each loop cycle so I end up
# with something like this:
# 1st loop
td height=15nbsp;/td
# 2nd loop.
td height=15 bgcolor=#CCnbsp;/td
# 3rd loop..
td height=15nbsp;/td
# 4th loop.
td height=15 bgcolor=#CCnbsp;/td
# and so on till the entire loop is completed
}
hope this make sense :)
TIA.

Hello all While traversing a loop across and array, how can I access array positions further down the array, like say if I am on a loop looking at position 23, how can I check the value of say position 24 or 32 while my loop counter is on position 23.

See if this gets you thinking along the right lines:
my $odd = 1;
while () { # some kind of loop...
if ($odd) {
# do something
$odd = 0;
}
else {
# do something else
$odd = 1;
}

To do that you might want to use: for and check on whether an item is defined
or not. Then you know the id you are on and can add or subtract depending on what you
need.
So for a starter, you could try:
for(my $MyId=0;$MyIdscalar(@MyArray);$MyId++) {
next if ( ! defined $MyArray[$MyId] );
my $MyCheckId = $MyId + 2; # looking at item two above
if ( $MyArray[$Myid] $MyArray[$MyCheckid] ) {
# do something
}else {
# do something else
}
}
I think you see what I mean.

been trying to come up with a way, while going through a loop to

I always do something more like:

while () {
print tr class='r, ($i++%2), ' ... /tr\n
}
The benefit here is that someday I can replace the 2 with 3 and have
three behaviors. Yes, that's a minor benefit.

The minus is of course readability. ;) You could accomplish something
similar with the ternary operator, to do it as Mike was, without
stylesheets.
Ironically, this was my first thought, but I changed my mind while I
was typing it. I don't think an extra line or two is a bad price to
pay for understanding what's going on. Of course, I'm pretty dumb and
need all the visual clues I can get.
