Re: No response from localhost

Hi Dharm,

Use the minimal snmpd.conf

syslocation  ServerRomm

syscontact  Admin

rocommunity  public localhost

rwcommunity  private localhost

Once you chage the snmpd.conf , make sure that you restart the agent and
check

Want excitement?
Manually upgrade your production database.
When you want reliability, choose Perforce
Perforce version control. Predictably reliable.
