I have this code here.

no information seems to be passed to @match and @nomatch. I have attached the input test file. Could someone help me determine why no information is being passed to these arrays ?
(information passes from @array fine)


open(INPUT, "<C:/Users/mickg/Desktop/Lessons/arrays/input.txt");

my $line = 1;
my @array = 1..6;

while(<INPUT>)
{
      my $text = added;
      print WRITE "my array: @array \n\n";
      print "$line\t $text \t $_ \n";
      print WRITE "$line\t $text \t $_ \n";
      $line += 1;
      my @match = grep { $_ eq $lines[5] } @lines[0..4];
      my @nomatch = grep {$_ ne $lines[5] } @lines[0..4];
      print WRITE "all matching numbers : @nomatch \n\n";
      shift @lines;
}
print WRITE "all matching numbers : @nomatch \n\n";
close (INPUT);

I have a perl script that is doing a REST call to a server .  The REST call is working as designed.  I now have to enforce TLS 1.2 for that REST API call in the perl script but I do not know what I have to modify.  Any help would be appreciated.

I have until 10/30/2019 to fix as the server receiving the REST call will begin to refuse TLS 1.0 connections.

I have this string that I use to echo the change to screen to make sure I like it, but it does not work right, I cant seem to get it to add the.db


for i in `ls`; do newname=`echo $i | sed 's/.arpa//'`; echo mv $i $newname; done

Please bare with me, I have never used Perl in my life and I'm attempting to modify an existing script from previous worker. Any help is much appreciated.

I have a perl script that loops through Cisco Switches / Routers and can run commands. I want to log all output and "show" commands to a log file. For example:

# create log files
open STDOUT, '>', "test.txt";
open STDERR, '>', "test-errors.txt";

# Enable Mode
@out = $session->enable($password); 

$session->cmd("show run int Gi1/0/1\n");
$session->cmd("show run int vlan 1\n");
$session->cmd("show int status | inc something-here\n");

Open in new window


This is just an example but I'm having trouble outputting it all to a text file. I've attempted to put something like this:

print $session->cmd("show run int Gi1/0/1\n");
print $session->cmd("show run int vlan 1\n");
print $session->cmd("show int status | inc something-here\n");

Open in new window


But doesn't work as expected.

Any help is much appreciated thank you

Is there an easy way to set up shortcuts using your own domain (but not break or involve the existing website)?

Say the domain is mydomain.com.  People currently can type mydomain.com or www.mydomain.com and it goes to the website.

I'd like to be able to set up shortcuts / redirects so  something like time.mydomain.com would redirect to a specific website (in this case, maybe www.time.gov).

This is for someone else.  A long time ago I found a perl script that I put on my website, called it index.cgi, and it had this info:

#!/usr/local/bin/perl       
$mainpage       = "index.html";
%domains = (      
'www.mydomain.com'          =>  'https://www.mydomain.com',      
      
#enter shortcuts here      
'time.mydomain.com'         =>  'http://www.time.gov',


#end of shortucts

'www.mydomain.com'          =>  'http://www.mydomain.com/index.html'      
      
);      
$server = lc($ENV{'HTTP_HOST'});if ($ENV{'HTTP_HOST'} =~ /(\d+)\.(\d+)\.(\d+)\.(\d+)/){$t='/'}else{if ($server !~ /^www./){$server = '' . $server;}}@domains = keys(%domains);foreach $domain(@domains){if ($domain eq $server){print "Location: $domains{$server}\n\n";$match="yes";last;exit}}unless($match){print "Location:  https://www.mydomain.com/index.html\n\n";exit}exit;      
      
 
That does what I'm asking about - enter loads of shortcuts and you can enter that subdomain and it takes you to the appropriate webpage.

Are there other ways via the DNS zone record or something else?  

Are there simpler ways to do this redirect of …

I have a list of over 800 server 2008 (some std, some R2, some enterprise). I need a script that can run either on my workstation or on a server in the environment that logs in to each server in the list, retrieves all successful logins (whis usernames and dates) and save those logins either to one large spreadsheet or to individual csv files that can later be imported into a spreadsheet.

I have yet to see a script or app for this that actually works. I do have a ps script that has to be uploaded to each server one at a time then run then manually retrieve the data but I just don't have enough time to do that kind of thing with over 800 servers.

An app or script (vb, ps, perl, whatever) that does this and runs from one location would be great. Help please!!!

Hi all,

 How to compare string within an array? That string contains backslashes, colon and paranthesis.

sample program:

use strict;
use warnings;

sub perl_func {
    my ($z, $x) = @_;

    print "\n";
    print "z: $z\n\n";
   
    my @lx=@$x;
    foreach my $tx (@lx)
    {
       
        if ($z !~ m|$tx|)
        {
            print "$z !~ $tx\n";
        }
        else
        {
            print "$z == $tx\n";
            return 1;
        }
    }
   
    print "\n";
    return 0;
   

}

#my @x = ("One", "Two", "Three", "Four", "Five");
#my $z = "Four";
#works fine for above x & z

my @x = ("One\\OnesPosition:Num (NumPerl)", "Two\\TensPosition:Num (NumPerl)", "Three\\HundresPosition:Num (NumPerl)", "Four\\ThosandsPosition:Num (NumPerl)", "Five\\TenThousPosition:Num (NumPerl)");
my $z = "Four\\ThosandsPosition:Num (NumPerl)";


if(perl_func($z, \@x))
{
    print "\nfound element\n";
}
else
{
    print "\nnot found element\n";
}

Hi

I have a Perl question.

I have an input that is "x                               "   it is 23 characters and I will get a number to adjust the x character back or forward with in the 23 character field.

Example

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
X

I might get -4 which means I need to adjust back 4 and would make it

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23
                                                                                    X


The problem is I am not sure how to program this.

I could get +5 or -10

Any help would be appreciated

Thanks

Hi Everyone

I have a perl script and I have an array and am using a foreach and am looping many times to update an XML file.
There are 2 foreach loops in the script. The outer loop is the data and the inner is searching the XML file to add the data to the specific node.
I'm using the XML::LibXML to search and add.

My question is:

Once I use the element in the array I want to get rid of it to make the foreach loop execute faster as the array would decrease in size.

The program now runs 3 hours. It would be good to speed it up.

Is there an easy way to do this?

Thanks for the help

Learn SQL Server Core 2016

Learn SQL Server Core 2016

This course will introduce you to SQL Server Core 2016, as well as teach you about SSMS, data tools, installation, server configuration, using Management Studio, and writing and executing queries.

Yesterday I installed FreeBSD on a virtual machine with some web tools to use as a hobby webserver.
My project includes perl scripts, but when I try to run them in my browser a get the whole script shown as a text, instead of getting executed as a program.
So I did some digging and found that I had to do some CGI configuration. So I added the line AddHandler cgi-script .pl to /usr/local/etc/apache24/httpd.conf, and I added the line Options ExecCGI to the apache server directives. I fiddled around with this for hours and still can't get it to work. What am I doing wrong?
I am using a web interface for the server called webmin, if that could be of importance.

Thank you for helping!

Hi

I have a large XML file and I need to remove the line
<INCOND NAME="A-OK" ...... />  or <OUTCOND NAME="A-OK" ...... />

in it if the line matches an entry in an Array (@LIST)


The array is @LIST with entries
A-OK
B-OK
C-OK
...

The entry from the @list could contain special characters.

There could be multiple line in the XML file with the same pattern.

I need to make it fast as possible.

Thanks

Require a shell/perl script with below steps.
1) When disk space reaches 75%, trigger a cron job and move the old .arc files to another location.
2) Clean up the files in a folder by keeping only 8 hours of data available and it should be run every 15 mins.

Thanks,

Hi All,

We have recently upgraded our Aix OS from 6.1 to 7.1, along with the Os the perl fileset got upgraded to 5.10.1 from 5.8.8, now we are getting the below issue.

Can't locate DBI.pm in @INC (@INC contains: /usr/opt/perl5/lib/5.10.1/aix-thread-multi /usr/opt/perl5/lib/5.10.1 /usr/opt/perl5/lib/site_perl/5.10.1/aix-thread-multi /usr/opt/perl5/lib/site_perl/5.10.1 /usr/opt/perl5/lib/site_perl/5.8.8 /usr/opt/perl5/lib/site_perl .) at /dispatch.pl line 3.
BEGIN failed--compilation aborted at /dispatch.pl line 3.

Can someone please help me to resolve the issue.

I'm thinking to reinstall the older version of perl i.e., 5.8.8, but I'm not sure if it works or not. And I couldn't even find if the 5.8.8 is still compatible with the Aix 7.1 TL 4 SP4. Thanks.

Krishna

I have a perl app that is currently connected to a MYSQL Database, but we would like to migrate the app to a sql server database. A page in the app executes two queries, the 1st is the primary and the second  gets its filter value from the 1st. The problem i'm having is, only the last row from the 1st query being executed in the second query. For instance if the 1st query returns the following
CrsNo   |Customer  | Response
723         Bill                  Urgent
724         Ken                 Urgent
725         Bob                 Urgent

The second query should query the database for each customer number that the first query provided, however, the only query that is executed is CrsNo 725. I have confirmed this with the sql profiler. The odd thing is the same code works fine with MYSql, I only run into this issue with sql server. Below is PERL Code and sql queries.
################## First Query

my $str = "select  distinct q.CRSNo,q.CustomerName,q.ResponseAction,
                           from crs.tbl_customer q
                         where q.CustomerName = '$cname' order by q.CRSNo";
my $temp1 = $dbh->prepare("$str");

      $temp1->execute;
while (my @aray = $temp1->fetchrow_array)
{
($crsno,$crscust,$response) = @aray;

################Second Query
$str2 = "select q.DepartmentInitial,q.ReviewStatusName
                                       from crs.tbl_department as q
                                       where q.CRSNo ='$crsno'  order by q.DepartmentNo";

$#dpt = -1;
      $#dptresp = -1;
      $temp2 = $dbh->prepare("$str2");
      $temp2->execute;

Hello ,

I need to write a script that reads the mark & masqueraded packets and for every 1/2 of a second it will ask to backend and reply the same answer to each question that comes from udp.
For ex.
Tsource is a counter strike packet. S.b. is making spoofed traffic of tsource , i want to masquerade this traffic to my perl module with marking packets with the destination ip. My script will see the mark and ask to the backend the answer of Tsource. and will answer this packet same for every half of second .
This samples should be given more like teamspeak TSINIT or other udp apps. Is that possible ?

If i block the tsource packet all the server is locking down , there is no logical solution like droping first packet (because the attacker sending 2 packets to server)  or blocking flood (because a companies all servers getting tsource at least once for giving game information , if i block floods for a number this time game lists are closing) . I need to find a way to build a proxy for this kind of application firewall proxies.
