Dear Sagar

These are nfs daemons and are controlled by

/etc/rc.config.d/nfsconf file.


thanks and regards

Thanks to Michal for the link

After reading the Document I have doubt

So nfsktcpd daemon is used for NFS over TCP .

Now by default all NFS request use TCP so does this mean the nfsd daemon is rarely used on in HP-11i

If you're running HP-UX 11i v1 or v2 and you're only using NFS/TCP then the nfsktcpd threads will be doing all the work and the nfsd daemons will do no real work.

You can confirm this with nfsstat. That command shows a breakdown of how many requests arrived on connection-oriented transports (TCP) vs. connectionless transports (UDP). If you don't see any UDP requests then your nfsd daemons should be idle.

The nfskd daemon, as you probably already read, was a placeholder for implementing a threaded model for NFS/UDP that we never completed so it does nothing.

If you're running 11i v3 there is only a single nfsd daemon process running and all the UDP and TCP requests are serviced by threads owned by this process.

Re: Need of the daemosn nfskd abd nfsktcpd

Hi Dave

Thanks for the information
So if I am using 11.11 and 11.23 then nfsktcpd daemon handles the NFS requests.
So there is need for only nfsd daemon which handles the TCP connections.

So Can I stopped the nfsd from running as this will reduce cpu utilisation.
