Description

Fix Text (F-17690r371457_fix)
The root role is required. Change the default snmpd.conf community passwords. To change them, locate the snmpd.conf file and edit it. # pfedit [filename] Locate the line system-group-read-community which has a default password of public and make the password something more random (less guessable). Make the same changes for the lines that read system- group-write-community, read-community, write-community, trap, and trap-community. Read the information in the file carefully. The trap is defining who to send traps to, for instance, by default. It is not a password, but the name of a host.
