Please don't act as if someone owes you an answer simply because you

I'm sure that there are people who have properly-configured systems, and
that they don't have troubles with DNS.

Then maybe the problem is with that software.

Could be. I don't know what that means, so I can't say.
If your system is properly configured, it may be that you've found a bug
in ActiveState's Perl. Try the standard distribution instead, and complain
to the folks at ActiveState, if theirs has a bug. Good luck!

I'm not sure what you mean; your prose is unclear. Here's my attempt at a
translation:
When I connect to the Internet, I have an IP address which is
assigned dynamically by my ISP. Each connection may have a
different IP address. The IP address is written to a logfile
at the time I make the connection.
> I use a webramp which a router with modems on it and it make the

Translation:
I use something called webramp. It may be that 'webramp' is
software, hardware, or my ISP's name, or maybe it's something
else entirely. It involves a router with modems on it, and the modems
make the connection to the ISP, but this is completely irrelevant
with respect to my current problem. Connecting to the ISP is the
only way I have found to obtain an IP address.

Translation:
I know that the IP address assigned will be in the range beginning
153.37.55.*. What I want my program to do is to grep some file (I
think it's that logfile) every hour to find the last entry with a
number in this range. I want to check to see whether this number
is the same as some other number, but I don't know what difference
that makes. Then I want my program to output the IP number.
> How can this be accomplished with a script.
Translation:
Please write this program for me.
You'll need to write this yourself. Try reading the Llama book (Learning
Perl) to learn how to open and read files. In order to start a utility
every hour, your system may have cron or a similar facility available. The
perlre, perlop, and perlfunc manpages should also be useful.
On the other hand, it might be faster and more reliable to parse the
output of a system utility which can report your networking status. Check
your system's docs to see whether there's such a utility.
Good luck!

That's not how you should do it. If your program needs to "become" another
user, it should be set-id. See the perlsec manpage, and your system's
documentation on set-id programming. It's potentially fraught with
security worries, so program with care. Good luck!

I am reading the perl cookbook right now. On page 227 it say "Less
common O_* flags somes available include O_SHLOCK, O_EXLOCK, ....
Consult your open(2) manpage..."
I am running FreeBSD and did consult my man page. The O_SHLOCK,
O_EXLOCK are available.
So, if write,
sysopen(SOURCE, $path, O_WRONLY|O_APPEND|O_CREAT|O_EXLOCK);
an exclusive lock will be made?
If so, how do I code it if the lock fails (ie, it is already locked)?
I mean, how do I wait until the file is available?

If you're following the proper protocol but some browser or server doesn't
cooperate, then it's the other program's fault. If you're not following
the protocol, then it's your fault. If you aren't sure about the protocol,
you should read the protocol specification. If you've read it and you're
still not sure, you should ask in a newsgroup about the protocol.
Hope this helps!

Yes.
For example in extended regexes like this one:
$string =~ s/ (
(^\w) #at the beginning of the line
| # or
(\s\w) #preceded by whitespace
)
/\U$1/xg;
$string =~ /([\w']+)/\u\L$1/g;
There can also be more than one space and/or tabs. Comments can also be
in the beginning of a line. And sometimes people even do multi-line
comments, as described in perlfaq7
How can I comment out a large block of perl code?
Use embedded POD to discard it: (..etc..)
#!/usr/bin/perl -w
print "Something ";
=for nobody
Here is some POD style commenting, which
can throw your whole concept of commenting way over...
=cut
print "under the bed is drooling.";
__END__
Hmmm....

It seems to me, that you want to use something like a

Are you sure that /bin/sendmail/ is the name of the program you want?
If you're using the proper commands to run another program from perl, but
the other program doesn't cooperate, then it's the other program's fault.
If you're not using the proper commands, then it's your fault. If you
aren't sure about the proper commands, you should read the program's
documentation. If you've read it and you're still not sure, you should ask
in a newsgroup about the program.

JP> to that directory whenever the callback is called.
having followed this thread, that seems to be a doc bug. i can't find
chdir anymore in your code below there!
if the callback is not chdir'd to the current dir, that is a significant
(if useful for OO, etc.) difference from the old file::find. that should
be highlighted more (when corrected).

Maybe you're having concurrency problems. Are you locking files properly
when that's needed?

The FAQ talks about using serial ports.

Perhaps, but they're not Perl-specific. You could use the same methods
with virtually any programming language.

Maybe you should check the docs, FAQs, and newsgroups about web-related
topics for this one.
Good luck!

Subject: Special: Digest Administrivia (Last modified: 12 Mar 98)
Message-Id: <null>
Administrivia:
Special notice: in a few days, the new group comp.lang.perl.moderated
should be formed. I would rather not support two different groups, and I
know of no other plans to create a digested moderated group. This leaves
me with two options: 1) keep on with this group 2) change to the
moderated one.
If you have opinions on this, send them to
perl-users-request@ruby.oce.orst.edu.
The Perl-Users Digest is a retransmission of the USENET newsgroup
comp.lang.perl.misc. For subscription or unsubscription requests, send
the single line:
subscribe perl-users
or:
unsubscribe perl-users
to almanac@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.misc (and this Digest), send your
article to perl-users@ruby.oce.orst.edu.
To submit articles to comp.lang.perl.announce, send your article to
clpa@perl.com.
To request back copies (available for a week or so), send your request
to almanac@ruby.oce.orst.edu with the command "send perl-users x.y",
where x is the volume number and y is the issue number.
The Meta-FAQ, an article containing information about the FAQ, is
available by requesting "send perl-users meta-faq". The real FAQ, as it
appeared last in the newsgroup, can be retrieved with the request "send
perl-users FAQ". Due to their sizes, neither the Meta-FAQ nor the FAQ
are included in the digest.
The "mini-FAQ", which is an updated version of the Meta-FAQ, is
available by requesting "send perl-users mini-faq". It appears twice
weekly in the group, but is not distributed in the digest.
For other requests pertaining to the digest, send mail to
perl-users-request@ruby.oce.orst.edu. Do not waste your time or mine
sending perl questions to the -request address, I don't have time to
answer them even if I did know the answer.
