Hi everyone, we ran into a problem with snmpd inside a LXC container. The container does not offer the neigh/default directories for ipv4 and ipv6. Therefore it cannot access the retrans_time_ms files inside the netsnmp_arch_interface_init() function and falls back to the deprecated retrans_time proc file.
/proc/sys/net/ipv6/neigh/default/retrans_time_ms This causes snmpd during initialization to access the deprecated proc file retrans_time of the available interfaces: /proc/sys/net/ipv6/neigh/<interface>/retrans_time Then the following kernel message will show up: > kernel: process `snmpd' is using deprecated sysctl (syscall) > net.ipv6.neigh.default.retrans_time; Use > net.ipv6.neigh.default.retrans_time_ms instead. The question is now, is this a snmpd problem or is this a LXC issue. One way to get this fixed would be to check for retrans_time_ms and if not available for retrans_time inside _arch_interface_flags_v4_get(). In that case it wouldn't be necessary to access the default directory at all. The same would go for the v6 function. Any feedback would be appreciated.
