I am using 5.7.2 and it works flawlessly. Not sure what John was running.
He seemed to be asking how to do the snmp_conf_Dir/hosts/XXX files.
I am asking in a separate thread about the Perl module (SNMP) that ships
with Net-SNMP and whether it should read those hosts files. The Readme
states that SNMP now calls init_snmp which should read the usual config
files BUT when I strace, perl never looks at the
Ssnmp_config_dir/hosts/XXX files - only at the
snmp_config_dir/{snmp,perl}.conf files
Any clues on the Perl parts? The hosts files work fine for me.
Thanks!
