snmpd hidden user?
While upgrading my NS-120 I saw the step "configure snmpd hidden user". What purpose does the hidden user serve? And who's it hidden from? Me? Sounds...suspicious...
Thanks!

Confirm the snmpd daemon is appearing on the netd file on nasdb:
$ grep snmp /nas/server/slot_2/netd
snmpd
Schedule a Data Mover failover and failback to reload the daemon or contact EMC Support for further assistance.
$ .server_config server_2 -v "snmpd"

I guess its an account on the data mover that server_netstat uses

I can't, it was just a item that scrolled by along with the progress bar while doing an upgrade of a Celerra NS-120 using Unisphere Service Manager. Just wondering what purpose it serves, and why it's 'hidden'.
Thanks!

That script "/nas/sbin/configure_snmp_user" doesn't give me any clues to what it actually does. I'm primarily concerned about the security implications. We're under some federal requirements regarding 'service' accounts, I think this may fall into that category.

That is not an account that can be used to access data – just for snmp info
