The man pages do not document any ntp.conf commands. The documentation is in /usr/doc/ntp-4.2.6p1/html, start from /usr/doc/ntp-4.2.6p1/html/index.html. "pool" is described in confopt.html.

Unnecessarily the peer was a stratum 1 server (if that's what the st column indicates). I understand it is bad NTP etiquette to peer with stratum 1 servers unless there is a real need for best accuracy.

Don't worry about that in case of pool servers. If a server is in the ntp pool, it can be used (via the *.pool.ntp.org DNS alias, as part of the pool). (The rules you think are about using the servers listed in the public stratum 1 ntp servers list.)

Thanks Petri

Found the local HTML OK. Similar to http://www.eecis.udel.edu/~mills/ntp/html/index.html but presumably more closely matched to the installed version.

That makes sense -- if the tier 1 server admins did not want the load they wouldn't have joined the pool. Happily means the tos line can be dropped from ntp.conf -- keep it simple.
