[Nut-upsuser] Arch Linux and Tripp Lite web snmp card issues.
Thanks for the quick response Charles! I may not have gotten the correct
output from the snmpwalk, let me know if the attachment is usable. Thanks!
New data added, here is the gdb output:
Reading symbols from /usr/bin/snmp-ups...(no debugging symbols
found)...done.
(gdb) run -a tripplite -DD

Do you need "set solib-search-path" or "set sysroot"?
