Subject: Does this module work with SNMP v3?
Date: Thu, 20 Apr 2017 20:56:44 +0000
To: "bug-SNMP-Effective [...] rt.cpan.org" <bug-SNMP-Effective [...] rt.cpan.org>
From: "Jones, Thomas D." <thojones [...] southernco.com>
Hello! First off, thanks for your wonderful module. It's super fast and efficient and has made my life a lot easier. However, we're moving to SNMP v3 for all the devices I'm polling and I'm having trouble finding documentation on this, or making it worse in general. Here's my code: my $effective = SNMP::Effective->new( master_time => 5, dest_host => "<ip>", get => $gref, callback => \&my_callback, max_sessions => 5, arg => { Version => "3", username => "<username>", authpassword => <authpasswd>, authprotocol => 'SHA', privpassword => <encryptpasswd>, privprotocol => 'AES', debug => 1, }, ); It simply times out. If I swap to v2c, everything is fine again. Forgive me for not including more details on my OS or perl installation, but they don't seem pertinent. Thanks for your help! Show quoted text

Subject: [rt.cpan.org #121260] Seg fault on v3 session
Date: Fri, 21 Apr 2017 18:04:06 +0000
To: "bug-SNMP-Effective [...] rt.cpan.org" <bug-SNMP-Effective [...] rt.cpan.org>
From: "Jones, Thomas D." <thojones [...] southernco.com>
Hello, So I've done more investigating and figured out that we had a firewall blocking initial v3 attempts. However, now when I try to connect via v3 (I can connect using these credentials just fine via the CLI utilty snmpwalk on Centos 6), I get a segmentation fault. Here's the output: Sessions/max-sessions: 1<1 at /usr/local/share/perl5/SNMP/Effective/Dispatch.pm line 122, <$READ> line 1. Unlocking lock at /usr/local/share/perl5/SNMP/Effective.pm line 510, <$READ> line 1. Calling callback for IP ADDRESS... at /usr/local/share/perl5/SNMP/Effective/Dispatch.pm line 230, <$READ> line 1.

Hi Thomas, This module is based on SNMP.pm which is part of the net-snmp distribution. On the one hand net-snmp should be healthy if you're able to use snmpstatus etc on the device, as it's the same software. On the other hand, the Perl interface SNMP.pm may not be working. I have never tried SNMPv3 with it. Do you have the module working with SNMP v2? So you could test manually with SNMP.pm and SNMP::Session: https://metacpan.org/pod/SNMP You could also try the alternative to SNMP::Effective which is Mojo::SNMP: https://metacpan.org/pod/Mojo::SNMP If you do not need the parallel high performance, you could also try SNMP::Info: https://metacpan.org/pod/SNMP::Info p.s. the official channel for reporting bugs is here: https://github.com/jhthorsen/snmp-effective/issues regards Oliver.
