in reply to snmpwalk in perl

Hello Nouhira,

Welcome to the monastery.

I am a bit stuck here. You do not want to use a module but at the same time you have provided the solution to your self:

`snmpwalk -v2c -$community $ip $oid`

What is wrong with this piece of code? Are you wondering how to store the stdout? Is it not working for you is it failing? Unless if you expect something else that you are not explaining.

    yes, so sorry for that. Im still in learning phase in perl, i wanted to perform snmpwalk for 3 to 4 IP's using snmpwalk command and store the result in an array, After that i want to use a 'for' loop to iterate that array and print the output for one IP at a time. I hope u understood my query.

      Hello again Nouhira,

      On this case a simple foreach loop with all the IPs should do for your case.

      Sample of code:

      #!/usr/bin/perl use strict; use warnings; my $oid = '1.3.6.1.2.1.25.2.2.0'; my @ips = qw(127.0.0.1 127.0.0.1); my $community = 'public'; foreach my $ip (@ips) { chomp(my @array = `snmpwalk -v2c -c $community $ip $oid`); }

      As a next step you should find a way to store your data for each IP. On this case my approach would be HASHES OF ARRAYS but it can also be done by ARRAYS OF ARRAYS. I would highly recommend to read the documentation to understand the difference from one to the other and also how to add data to them and how to access the data after.

      Then Job done.

      If you have any problems after experimenting with the code then you can ask us again.

      Hope this helps, Thanos
