[edit]
Why can't I change sysLocation (or sysContact)?
Assuming that the access control settings should allow this, another
possibility for the 'sysLocation' and 'sysContact' objects is that
you've got a configuration option in the
'snmpd.conf' file which
already sets the corresponding value there.
Earlier versions of the Net-SNMP agent would allow you to write to
these objects, but the new value would be forgotten the next time the
agent was re-started. More recent versions of the agent reject such
write requests if there's a value configured via the 'snmpd.conf' file.
If there isn't such a config setting, then the write request will succeed
(assuming suitable access control settings), and the new value will be
retained the next time the agent restarts.
