Subject: a secure way to do a "rsh"?
Message-Id: <79unhg$qrn$1@nnrp1.dejanews.com>
Can someone provide me some info on how I could go about doing something like
a "rsh <hostname> command" from within a perl-script.
I'm running Apache with all scripts owned by nobody, so in order to be able to
rsh a command to a remote host, I either need to set up a trust relationship
between the host and that user (no thanks), setuid on the script or....[Your
suggestion here] =).
Additional info: Apache is on on box, I'd like to be able to dynamically get
the status of some backups on other boxes. Currently I have a script cron'd
once daily that runs on the remote box with output going into my NFS mounted
home directory which is then copied to the Apache directory, but this is time
consuming and not dynamic. Any suggestions would be appreciated.

It's gotten even worse! Good lord!
Date::Manip is a great module if you really need to be able to do all of
that stuff. But usually you *don't*. And when you don't, it's just about
the poster child for "let's see how much code we can make Perl compile to
do this simple little date calculation."
Nearly all of the time, in a typical program, you can get away with just
localtime, POSIX::strftime() (which is dynamically loadable C, just an
interface to your C library, and reasonably fast), and some simple tricks.
If you really need to parse dates, Date::Parse from TimeDate is generally
sufficient. And it's a lot less weight.

@ISA is Perl's mechanism for inheritance. If perl can't find a method in
the current package (mypkg::MyExports), it will look in the each package
whose name is in the @ISA array. This behavior is mentioned on page 292
of the O'Reilly "Programming Perl" book.

Well, Perl is written in C, so you could just as easily have asked in
a newsgroup dealing with C language issues.
Seriously, your post contained no Perl content whatsoever. It was
essentially a job posting, and I was calling your attention to that
with my usual overbearing sarcasm.
An example of Perl content would be: "Why does -w not emit a warning
when I use racist variable names?" or "How are hashes implemented?"

It can certainly be done using Win32::API. I do it in
Win32API::CommPort.pm (bundled with Win32::SerialPort on CPAN).
Tye McQueen was working on a Win32API::File which would
do it easily - but I don't recall seeing that one released yet.
Of course, none of those is cross-platform ;-(

Message-Id: <Pine.OSF.4.00.9902120040340.16165-100000@yoyo.cc.monash.edu.au>
As you can see with my subject .. I have trouble creating a file using
HTML.
here is my tragic situation - I am doing form processing and I wish to
create a file with respect to the person's name and then input data into
it. When I go onto the next page of my form and press Submit... An error
occurs saying that the file does not exist. So I think that it is probably
that the file was not created in the first place.
here is an abstract of my code
$filen = $FORM{filename};
open (RECORD,">$filen".".txt")||die"Cant create file";
and for sequential pages
open (RECORD,">>$filen".".txt")||die"Cant create file";
Something tells me that I cannot do this... is it possible? Or maybe I
should construct a .pl file that stores the data in fields.
Or if anyone else have any ideas... would really appreciate if you could
help me.

No I cannot really think of any better way to do this, except maybe the shell

Well, you actually *do* have some control over this.
Here's a requote of your original code fragment, with a suggested
change appearing underneath your `exec' call ...
> I am trying to do the following... (simplified code)
>

Suggestion:
exec("exec $BinaryExe 1>$stdoutfile 2>$stderrfile");

> kill('HUP', $pid); #Kill off the child.
The outer `exec' replaces the Perl process with your shell, which
then runs the command you specified. The inner `exec' tells the
shell to replace itself with the program whose name is contained
in `$BinaryExe'. Therefore, your `$pid' variable will contain the
process ID of the running program whose name is contained in the
variable `$BinaryExe'.
There are some caveats here, of course ... but this approach might
work for the cases that your program is dealing with.

Hi !
I am looking for a plotprogram with the following
features to monitor some reference values of a
running application program while to program
is running.
-) simple command language
to define some parameters at startup
(like gnuplot; logarithmic scaling for example )
-) output to X11-window
-) some X11 menues to rescale etc
-) reading data continuosly from pipe
and add them continuosly to the figure
-) menu buttom to print present picture
(in postscript)
-) running under linux
( sources available )
Does a program with these features (or some of them) exist ?
All hints welcome
Thanks
Tobias

I'm wondering myself. I use Perl (MacPerl on MacOS 8.1, Perl 5.005 on
Linux, and ActiveState 509 on Win 98) a fair bit, and I've never noticed
that anyone is pushing an agenda. I can get to resources concerning any
platform from www.perl.com in short order. Mind you, in many cases I
already know shortcuts, so I'll go to a more specific URL etc.
I'd be really hard-pressed to think of a useful resource on www.perl.com
that's been "trimmed", whatever that means.
In Mr Pierce's eyes surely the fact that ActiveState is running some
generic Perl mailing lists must be also cause for some suspicion, or the
fact that www.ptf.com (Prime Time Freeware) is handling MacPerl links. I
wonder what he'd have to say about that? :-) (In my own experience I find
that these outfits are acting very responsibly - I can get my mail
digests, or do my downloads, or do my web browsing, without being
bombarded with company info or being "steered").
Rather a bizarre complaint...

Subject: Running script locally in browser
Message-Id: <79upbk$e50$1@msunews.cl.msu.edu>
I am trying to view a script in my browser using Linux 2.0.36 from my machine. The problem is that I just get the actual script showing up in the browser instead of the output. I know the script works, because I can run it from the command line and also after I ftp it up to my ISP. Is there a setting that I need to set on my system? Permissions are set correctly (chmod o+x file.cgi). Do I need a "cgi-bin" server? I have a good grasp on the OS basics, but I will need more detail when dealing with any
thing deeper. Thank you in advance, and please reply to swanbria@pilot.msu.edu

I like Larry's semantics better. If I had a bigger vocabulary, I might
have used the word, "implements", myself.

Well, after 6 months, here's the answer to the quiz: what do we do about
comp.lang.perl.moderated. Answer: nothing.

]It is possible to subscribe to comp.lang.perl.moderated as a mailing list.
]To do so, send mail to majordomo@eyrie.org with "subscribe clpm" in the
]body. Majordomo will then send you instructions on how to confirm your
]subscription. This is provided as a general service for those people who
]cannot receive the newsgroup for whatever reason or who just prefer to
]receive messages via e-mail.
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.
