Hello,

I am configuring OCS Server using the following two documentations:

http://wiki.centos.org/HowTos/OCSNG
http://www.howtoforge.com/how-to-ins...-on-centos-5.5

Getting below error during installaton:

Checking for Apache:BI PERL module...
*** ERROR: PERL module Apache:BI is not installed !

HI all,
I'm writing a perl script to automate VM UUID transformation into a format used by our ServiceNow CMDB/discovery.

Anyone know which perl module to include to use the string length function?

Alternately, how would I determine which perl modules exist that are available to include, vs. which functions each module contains?

thanks in advance,

Hi All,

I have perl script which I am trying to run on 1st Monday via cron job.
So I scheduled it as follows:

0 0 1-7 * * root ["$(date '+%a')" = "Mon"] && /usr/bin/perl script.pl

But then it didn't run so checked cron log and it seemed like its missing the command. so added a \ in front of %a and then it picked up the whole command as per cron log.

But still it didnt ran the script. I then change the script to just && echo "test">/tmp/test

Still nothing. if I run it as /usr/bin/perl script.pl it runs though

Thanks in advance.

Hi All,

I'm not a perl programmer, so please help me to disable warning messages. I tried like commenting 'use strict' and 'use warning' in perl program. But it is not working.

All I want is to disable warning messages.

Please note its not actual ping program, But a perl wrapper for ping to display ping output in color (Cope).

Below is output:

Code:

$ ./ping google.com

Works fine when error redirected to /dev/null

Unfortunately, I cannot use output error redirection because all the perl programs are in PATH.

Actual ping perl program:
Code:

#!/usr/bin/env perl
use App::Cope;
use App::Cope::Extra qw[ping_time percent_b];
use Regexp::Common qw[net];

sub process {

  # header
  line qr{^PING (\S+)} => 'blue bold underline';

  # ping replies
  line qr{time=([0-9.]+ ms)\b}    => \&ping_time;
  mark qr{\($RE{net}{IPv4}\)}     => 'blue';
  line qr{(?:icmp_seq|ttl)=(\d+)} => 'bold';
  line qr{^(?:\d+ bytes )?[Ff]rom ([^:\s]+)} => 'blue bold';

  # final ping statistics
  line qr{(\d+% packet loss)} => \&{ percent_b 0, 1, 26 };
  line qr{min/avg/(?:max/mdev|ewma/max)\s=\s
	  ([0-9.]+)/    # minimum
	  ([0-9.]+)/    # average
	  ([0-9.]+)/    # maximum or moving average
	  ([0-9.]+\sms) # mean deviation or maximum
       }x => ( \&ping_time ) x 4;

}

run( \&process, real_path, @ARGV );

Code:

$ head -n15 /usr/local/share/perl/5.20.2/App/Cope.pm
#!/usr/bin/env perl
package App::Cope;
#use strict;
#use warnings;
use 5.010_000;

I have a little bash script that cats out a file and tells me if there is a line
where the 11th column has more than 6 characters in it.
It emails me where there is a bad line in a file - bead meaning that it will break a
donwstream process.

anyhow when i get the email saying that there is a bad file i just log in to the pc via
vpn and the I sed out the lines from the file that I get in the email. The bad lines are
always in danny.csv not danny1.csv
It has been the same lines killing the downstream process for a few weeks, so i put the "sed -i's" into
the script and it does it automagically.

[CODE]
for i in danny.csv danny1.csv
do
cat /come/and/play/with/$i | perl -ne 'print if length((split /,/)[10]) > 6' | mail -s "danny.csv bad line" casper@casperr.com
done

#it would be nice to find a perl change the file in place
sed -i '/D,642,0642,UBF,EVL,,M,,S,S,FOREVER,213,213,/d' /come/and/play/with/us/danny.csv
sed -i '/D,642,0642,UBF,EVL,,M,,S,S,QSP-U=C,4,4,/d' /come/and/play/with/us/danny.csv
[CODE]

However when a new line gets put into this file, I am going to have to log in and take out the line.
SO I have been trying to write a perl one liner that will edit the file in place, like sed, and make a
backup of the file. I just need a perl one liner that will delete any line where the 11th columns has more
than 6 characters in it.
[CODE]
perl -p -i.bak -e 's/\,\w{7}\,//g - which does not work.
[CODE]
I tried something like this:

[CODE]
perl -nle 'print if /\,\w{7}\,/' /come/and/play/with/us/danny.csv
[CODE]
but that does not catch the QSP-U=C and it catches more lines than just the
FOREVER. for a solutinog I need to focus on the the 11th column.

Hello

I try to install the epel repository so I can install ejabberd.

I do not have epel, it seems :

Code:

[root@serv src]# ls /etc/yum.repos.d/
CentOS-Base.repo  CentOS-Debuginfo.repo  CentOS-fasttrack.repo  CentOS-Media.repo  CentOS-Vault.repo  n2.repo

So I try to install epel :

Code:

[root@serv src]# rpm -Uvh http://download.fedoraproject.org/pub/epel/6/x86_64/epel-release-6-8.noarch.rpm

	package epel-release-6-8.noarch is already installed

But when I try to install ejabberd :

Something is wrong with epel.

 You could try using --skip-broken to work around the problem
 You could try running: rpm -Va --nofiles --nodigest

Please advise

Thanks in anticipation

I am currently running a system simulation on multiple files.
I have a computer algorithm written in perl to run "system" simulations for all the files I need

What I am trying to do is put multiple files into one file, only problem is that its not doing exactly what I need it do

Example:

I am "cat txt0.txt txt1.txt txt2.txt txt3.txt > allfiles.txt"

I need it to read as

txt0.txt
txt1.txt
txt2.txt
txt3.txt

Instead its taking all the files and taking the information within each txt file and putting them all together. Info that looks like this


fdfasdfqwdefdfefdkfkkkkkkkkkkkkkkkfsdfasdxfewqfe..........

all clustered together

you get the picture ?

I am really confused how to get this to work, there are over 100 files that need to go into a single file.
That way when I run it through the perl algorithm I created, I can do it in one shot.

Hi all.
RHEL 6.0 in Virtual Box, network is ok, it can resolve all repos (f.e. dl.fedoraproject.org, nginx.org),
but when I'm trying
Code:

# rpm -Uvh http://nginx.org/packages/rhel/6/noarch/RPMS/nginx-release-rhel-6-0.el6.ngx.noarch.rpm

I get:
Code:

curl: (6) Couldn't resolve host

When I'm trying with ip instead name:
Code:

curl: (22) The requested URL returned error: 404

Only rpmforge repo enabled, but it can't find any packets for install/update.

What can I do?
Thanks.

So I'm on the last step of this article to run vmware-install.pl to start installation of my VMware tools and I'm getting this error.

[root@LinuxTest01 vmware-tools-distrib]# ./vmware-install.pl
-bash: ./vmware-install.pl: /usr/bin/perl: bad interpreter: No such file or directory.

I do a ls in the directory and it shows the installer in there.
[root@LinuxTest01 vmware-tools-distrib]# ls
bin doc etc FILES INSTALL installer lib vmware-install.pl


The only step I didnt do in this article is the prereq. first step because Yum is always trying to connect to the internet and my Centos 7 box is on a classified network with no internet access.
