[Bug 250549] Re: Wrong interface speed from snmpd running as snmp user

[Bjorn Ruud]

** Description changed:

  snmpd reports wrong interface speed when it is run as the snmp user.
  Running snmpd as root gives the correct result. Debug output suggests a
  permission problem. The gigabit network interface speed is correctly
  determined at startup, but fails when the owner of the process switches
  from root to the snmp user (or so I assume). After failure snmpwalk
  reports a speed of 10 Mbit/s for all interfaces.
  
  Using snmp user:
  
  # snmpd -f -Le -Lf /dev/null -u snmp -I -smux -p /var/run/snmpd.pid -DmibII/interfaces
  registered debug token mibII/interfaces, 1
  netsnmp_assert !"registration != duplicate" failed agent_registry.c:535 netsnmp_subtree_load()
  netsnmp_assert !"registration != duplicate" failed agent_registry.c:535 netsnmp_subtree_load()
  netsnmp_assert !"registration != duplicate" failed agent_registry.c:535 netsnmp_subtree_load()
  mibII/interfaces: ETHTOOL_GSET on eth0 speed = 1000
  mibII/interfaces: ETHTOOL_GSET on eth0 speed = 1000
  NET-SNMP version 5.4.1.2
  mibII/interfaces: ETHTOOL_GSET on eth0 failed
  mibII/interfaces: SIOCGMIIPHY on eth0 failed
  
  
  Using root user:
  
  # snmpd -f -Le -Lf /dev/null -I -smux -p /var/run/snmpd.pid -DmibII/interfaces
  registered debug token mibII/interfaces, 1
  netsnmp_assert !"registration != duplicate" failed agent_registry.c:535 netsnmp_subtree_load()
  netsnmp_assert !"registration != duplicate" failed agent_registry.c:535 netsnmp_subtree_load()
  netsnmp_assert !"registration != duplicate" failed agent_registry.c:535 netsnmp_subtree_load()
  mibII/interfaces: ETHTOOL_GSET on eth0 speed = 1000
  mibII/interfaces: ETHTOOL_GSET on eth0 speed = 1000
  NET-SNMP version 5.4.1.2
  mibII/interfaces: ETHTOOL_GSET on eth0 speed = 1000
+ 
+ Note: The output is from version 5.4.1.2 which I packaged for testing
+ purposes, but the problem is the same with version 5.4.1.
