ActivePerl error message? Router script. Please help.Newbie

Hi,

I have installed ActivePerl on Windows XP SP2 professional and have
tried running a script to restart my router: it always gives out this
message:

Can't locate Net/Telnet.pm in @INC (@INC contains: C:/Perl/lib
C:/Perl/site/lib .) at c:\inetpub\wwwroot\perl\router.pl line 5.
BEGIN failed--compilation aborted at c:\inetpub\wwwroot\perl\router.pl
line 5.

By default ActivePerl has installed Perl has been installed C:/Perl

I am running IIS.

The examples given in activeperl say that
"Note: the examples assume that PerlEx is installed on this machine,
and that the address http://localhost/PerlEx/scriptname is valid."

So I created a directory in c:\inetpub\wwwroot\ called perl and copied
and pasted all the files from C:/Perl into this directory in an attempt
to get this localhost to work. I have been running my script in
c:\inetpub\wwwroot\perl\
I've typed into Internet Explorer: http://localhost/perl/router.pl and
get the above error.

The script I have been trying to get to work is below:

I also tried turning on the starting the telnet service XP but this
didn't make any difference.
************************************************** *************

Here's some Perl that I've been playing with at home and at work
(being diverted from seeing some friends on Saturday morning to detour
into work to reboot the router provides an incentive to make sure the
ADSL line stays up). I run it from a cron job every 5 minutes.

Work: Vigor2600
Home: SpeedTouch 510

Both of them sometimes need a kick.

Notes: you will need to:
run the script as root if you use ICMP echo requests
change the IP addresses that it pings
change the username and password
change the command to reboot the system
do a bit of tidying up, especially if you are using Windows

Apologies to any Perl hackers out there for the coding style, from an
old fart who still thinks in Algol-60, -68, Fortran and C.

This message says it all: Can't locate Net/Telnet.pm at line 5.

[...lots of stuff snipped here...]

: use Net::Telnet; # And this is line 5 of your code.

[...code snipped...]

By default, ActiveState's Perl installation doesn't contain the Net::
Telnet module, only Net::HTTP is there. You just have to install Net::
Telnet from CPAN, ideally via ActivePerl's install manager.

The other measures you described in your mail are not necessary; if
ActiveState Perl is allowed to install properly, then it will any .pl
script anywhere will start up.

Hi,

Thanks Oliver for your help.

I have added all the .pm files from CPAN in the appropriate directories

Telnet.pm
Mailer.pm
Syslog.pm
template.pm

Please could you explain this error message:

Undefined subroutine &main:penlog called at
c:\inetpub\wwwroot\perl\router.pl line 38.

Thankyou.

Line 38 says:

openlog( "routerping", "", "user" );

With your lack of experience and expertise, how do you know you installed
them in the correct directories?

Please use ppm which is distributed with AS Perl to find and install
packages.

What does line 42 say?

Did you install manually or let the package makefile do the work?

No, I can't. The following complete minimal example does not produce
any error message on my system:

#!/usr/bin/perl
use warnings;
use strict;
use Sys::Syslog;
openlog("","","user");
__END__

Can you try this and verify?

Oliver.

Just a guess but `openlog` may be a Sys::Syslog method... (I thought
Sys::Syslog was Unix only too but maybe there's been some kind of Win32
port).

why didn't you do:

C:> ppm install Net-Telnet

?

Note that if you have set up your Win XP Pro properly, you have to run the
command prompt as Administrator (or a user with admin rights) in order to
be able to execute ppm. If it works out of the box, you probably should
rethink your account rights.

Hi,

Thanks for all your help. I installed

> template.pm manually because I couldn't work out how to get ppm to do anything. Now I've got it ppm working.
So now I've:
1 uninstalled ActivePerl
2 Restarted WinXP Pro
3 deleted c:\Perl to remove any of my previous manually installed .pm
files.
4 Reinstalled ActivePerl
5 Tried running the Perl script mentioned in the first post in this
thread.
6 Of course got the same error message as 1st mentioned:
C:/Perl/site/lib .) at c:\inetpub\wwwroot\perl\router.pl line 5.
BEGIN failed--compilation aborted at c:\inetpub\wwwroot\perl\router.pl
line 5.
7 Did C:> ppm install Net-Telnet
8 Ran Perl Script as mentioned in the first post.
9 Get error:
Can't locate Sys/Syslog.pm in @INC (@INC contains: C:/Perl/lib
C:/Perl/site/lib .) at c:\inetpub\wwwroot\perl\router.pl line 7.
BEGIN failed--compilation aborted at c:\inetpub\wwwroot\perl\router.pl
line 7.
10 Did c:>ppm search sys-syslog
Searching in Active Repositories
No matches for 'sys-syslog'; see 'help search'.

Does this mean as Charles DeRykus says that there is no Win32 port of
Sys-syslog?

Is there anyway of getting this script to work in windows?

When I run:
#!/usr/bin/perl
use warnings;
use strict;
use Sys::Syslog;
openlog("","","user");
__END__
I get the same error message:

Can't locate Sys/Syslog.pm in @INC (@INC contains: C:/Perl/lib
C:/Perl/site/lib .) at c:\inetpub\wwwroot\perl\olivertest2.pl line 4.
BEGIN failed--compilation aborted at
c:\inetpub\wwwroot\perl\olivertest2.pl line 4.

>What does line 42 say?
if ( $p->ping($ip) )

Thanks. Are there any similar scripts out there that may do the same
thing that would work in Windows. Thanks.

If you don't really need the logging capabilities, you could always just
comment out line 32...?

[...]line 32...[...]

By which, of course, I meant "38"!
