snmpd loudly complains every 3 seconds about a failure reading /proc/net/if_inet6 if the system does not have IPv6 support: Jan 1 00:00:12 buildroot daemon.err snmpd[92]: ipaddress_linux: could not open /proc/net/if_inet6: No such file or directory Jan 1 00:00:15 buildroot daemon.err snmpd[92]: ipaddress_linux: could not open /proc/net/if_inet6: No such file or directory Jan 1 00:00:18 buildroot daemon.err snmpd[92]: ipaddress_linux: could not open /proc/net/if_inet6: No such file or directory Jan 1 00:00:21 buildroot daemon.err snmpd[92]: ipaddress_linux: could not open /proc/net/if_inet6: No such file or directory Add an upstream patch to only print this warning once, rather than on every poll iteration.

Subject: [PATCH] MIB-II: Only log once that opening /proc/net/if_inet6 failed
|
|
|
|
If IPv6 has been disabled (ipv6.disable=1) then opening /proc/net/if_inet6
|
|
fails. Only log this once instead of thousand of times a day.
