net-snap-trap is missing on Centos 8 repos

[augustogomez]

I am trying to enable SNMP traps on a zabbix 5.0 appliance. Every thing went well until restarting snmptrapd. got the following error:

embedded perl support failed to initialize (perl_parse(/usr/share/snmp/snmp_perl_trapd.pl) returned 2)

Then found that is because net-snap-perl was not installed, which I did notice but skipped.

When trying to install the package got the following error:

[root@appliance ~]# yum install net-snmp-perl
Last metadata expiration check: 0:10:19 ago on Fri 26 Jun 2020 07:35:33 AM UTC.
No match for argument: net-snmp-perl
Error: Unable to find a match: net-snmp-perl

It seems that net-sum-perl is no available at the official CentOS repositories. Some where I read that it was available at the PowerTools repository, but is not:

[root@appliance ~]# yum repolist
repo id repo name
AppStream CentOS-8 - AppStream
BaseOS CentOS-8 - Base
PowerTools CentOS-8 - PowerTools
extras CentOS-8 - Extras
zabbix Zabbix Official Repository - x86_64
zabbix-non-supported Zabbix Official Repository non-supported - x86_64

Any suggestion on how to get the package will be welcomed.

SOLVED.

net-snmp-perl is not included in CentOS 8 standard repos. All net-snmp and perl components need to be installed manually from an external repository.

The only caveat is that net-snmp version on CentOS repos is 5.8-14 and the one available is 5.8-7. Seems to work.

Had to remove first newest net-snmp package for it to work.

Here's what I did:

yum update

yum install wget
yum install tar

wget repo.okay.com.mx/centos/8/x86_64/release//net-snmp-perl-5.8-7.el8.2.x86_64.rpm
wget repo.okay.com.mx/centos/8/x86_64/release//net-snmp-5.8-7.el8.2.x86_64.rpm
wget repo.okay.com.mx/centos/8/x86_64/release//net-snmp-utils-5.8-7.el8.2.x86_64.rpm
wget repo.okay.com.mx/centos/8/x86_64/release//net-snmp-agent-libs-5.8-7.el8.2.x86_64.rpm
wget repo.okay.com.mx/centos/8/x86_64/release//net-snmp-libs-5.8-7.el8.2.x86_64.rpm

wget www.city-fan.org/ftp/contrib/yum-repo/rhel8/x86_64/perl-Graphics-TIFF-6-4.el8.x86_64.rpm
wget www.city-fan.org/ftp/contrib/yum-repo/rhel8/x86_64/perl-PDF-API2-2.033-6.el8.noarch.rpm
wget www.city-fan.org/ftp/contrib/yum-repo/rhel8/x86_64/perl-Font-TTF-1.06-8.el8.noarch.rpm

yum config-manager --set-enabled PowerTools

umask 0022
yum install perl rrdtool rrdtool-perl httpd
yum install epel-release ed bc sharutils

yum install perl-TimeDate perl-XML-Simple perl-XML-SAX perl-XML-LibXML perl-Env perl-CGI perl-Data-Dumper perl-LWP-Protocol-https perl-libwww-perl libxml2
yum install net-snmp-perl-5.8-7.el8.2.x86_64.rpm net-snmp-5.8-7.el8.2.x86_64.rpm net-snmp-utils-5.8-7.el8.2.x86_64.rpm net-snmp-libs-5.8-7.el8.2.x86_64.rpm net-snmp-agent-libs-5.8-7.el8.2.x86_64.rpm
yum install perl-PDF-API2-2.033-6.el8.noarch.rpm perl-Font-TTF-1.06-8.el8.noarch.rpm perl-Graphics-TIFF-6-4.el8.x86_64.rpm

Here's a sample /etc/snmp/snmptrapd.conf entries that work:

authCommunity execute,log public
traphandle default perl do /usr/bin/zabbix_trap_receiver.pl
[snmp] logoption f /var/log/snmptrapd.log

The Zabbix developers are indeed aware of the problem you encountered, see: https://support.zabbix.com/browse/ZBX-17192 and also the issue it relates to.
