Hello everyone,
I've looked everywhere I could and I cannot seem to get a definitive
answer as to the
[subtle] differences of a server line and a peer line. I realize that
if its a peer, the two
boxes will use each other as servers. But Im curious if there is a
difference in:
Box A (10.20.0.1):
server 10.20.0.2
Box B (10.20.0.2):
server 10.20.0.1
And:
Box A (10.20.0.1):
peer 10.20.0.2
Box B (10.20.0.2):
peer 10.20.0.1
Also, if I they are peered correctly, do I even need to explicitly set
the peer on Box B?
I recently had the fun task of making sure ~20 servers (in three
different locations) stay synced.
I know that I could just set them up 'blindly' for all of them to just
use the pool, but that is obviously
wasteful. For example, on most of my boxes I have a setup like:
restrict default nomodify notrap nopeer
restrict 10.20.0.0 mask 255.255.0.0 nomodify
restrict 127.0.0.1
server 127.127.1.0
fudge 127.127.1.0 stratum 10
server 0.pool.ntp.org # the 'other edges' connect to
different external servers.
peer 10.20.17.10
peer 10.20.37.4
peer 10.20.37.7
peer 10.20.37.13
peer 10.20.37.14
peer 10.20.41.21
driftfile /var/lib/ntp/drift
Should I instead have the boxes that are on the same phsyical LAN as
peers, and the rest as
servers? (Basically, have them 'clustered' together)
Okay, last question. Is there a (practical) limit to how many
servers/peers I can have setup?
My apologies if these are 'noob'-type of questions, but Ive been
curious for too long.
Sincerely,
mm_202.
