(OSM) Net::Pcap Error

Posted: 25 Jun 2020, 21:10

I have OSM installed on a few servers and I'm running into some weird errors I can resolve. The original error was:
*ERROR* Net::Pcap failed to install, see /etc/osm/osmpcap.log. Packet inspection feature has been disabled in osm.
To which i installed pcap on the servers that were affected via

Code: Select all

sudo yum install perl-Net-Pcap
yum install libpcap libpcap-devel -y
I later saw this post ( viewtopic.php?t=11168 ) where it suggested to run

Code: Select all

sh /etc/osm/osmpcap.sh
and then review the logs at

Code: Select all

cat /etc/osm/osmpcap.log
to verify it installed correctly. Looking at the log, this is what it shows me:

Code: Select all

looking for -lpcap... yes
checking for pcap_lib_version() in -lpcap... yes
detecting available functions... ok
Checking if your kit is complete...
Looks good

So it says that -lpcap is found and the right version yet I'm getting tons of function not found errors. Any idea what is going on? I seem to be able to enable SMTP packet inspection in the configuration without error, just wasn't sure if this was normal.
