title: Net-SNMP: snmpwalk "timeout: No Response from localhost:1161" using Net-SNMP v5.4.3
body: <p>I'm new to Linux. I'm writing an SNMP extension agent using the MIB for Dummies (<a href="http://www.net-snmp.org/wiki/index.php/MIB_for_Dummies" rel="nofollow">http://www.net-snmp.org/wiki/index.php/MIB_for_Dummies</a>) config file (mib2c.mfd.conf). I successfully created my executable, adeSensorsTable, using my adeSensorsTable.MIB (mib2c util auto-generated the C source code from adeSensorsTable.MIB which I compiled into an executable). I then ran my executable:</p>
  
  <p>./adeSensorsTable -f -L -DadeSensorsTable -M localhost:1161</p>
  
  <p>I'd have a warning as I single stepped through the code:</p>
  
  <p>iquerySecName has not been configured - internal queries will fail
  Warning: no access control information configured.
  (Config search path: /etc/snmp:/usr/share/snmp:/usr/lib/snmp:/home/ken/.snmp)
  It's unlikely this agent can serve any useful purpose in this state.
  Run "snmpconf -g basic_setup" to help you configure the adeSensorsTable.conf file for this agent.
  [init_smux] bind failed: Permission denied</p>
  
  <p>On a separate terminal I ran:
  snmpwalk -v 1 -c public localhost:1161</p>
  
  <p>adeSensorsTable terminal would return:</p>
  
  <p>Connection from UDP: [127.0.0.1]:52684->[127.0.0.1]</p>
  
  <p>Connection from UDP: [127.0.0.1]:52684->[127.0.0.1]</p>
  
  <p>My snmpwalk terminal would return:
  Timeout: No Response from localhost:1161</p>
  
  <p>I'm not sure if snmp extension agent's warning is the show stopper in this case. I'd appreciate if someone could provide some pointers to my timeout issue. Thank you in advance!</p>
