Hello all, having 2 GPS sources and 4 peers to each other (see below the setup), When turning on 5th and 6th peers, they disturb my setup. Is it possible to restrict to those 4 peers only and send time to stratums lower than 2 as well? (example shown below with partial solution and error on stratum3 client).
Can somebody suggest me a workaround and confirm the existing setup? Thanks, Peter gps1 local.xx (.xx) xx.xx.xx.xx stratum1 gps2 remote.yy (.yy) yy.yy.yy.yy stratum1 -------------------------------- local.a1 xx.xx.xx.a1 stratum2 local.a2 xx.xx.xx.a2 stratum2 remote.b1 yy.yy.yy.b1 stratum2 remote.b2 yy.yy.yy.b2 stratum2 ------------------------------- local-annoying.c1 xx.xx.xx.c1 stratum2 local-annoying.c2 xx.xx.xx.c2 stratum2 -------------------------------------- local.test xx.xx.xx.t1 stratum3 [email protected]:~# ntpq -pn remote refid st t when poll reach delay offset jitter ============================================================================== *local.xx .GPS. 1 u 1 16 377 0.344 -0.037 0.046 +remote.yy .GPS. 1 u - 16 377 34.258 -0.074 0.273 -local.a1 xx.xx.xx.a1 2 u 12 16 377 0.286 0.043 0.015 +remote.b1 yy.yy.yy.b1 2 u 3 16 377 33.555 -0.016 0.055 -remote.b2 yy.yy.yy.b2 2 u 7 16 377 33.700 0.049 0.281 +local-annoying.c1 yy.yy.yy.c1 2 u 12 16 377 0.216 0.043 0.044 <--why? how to get rid of it? +local-annoying.c2 yy.yy.yy.c2 2 u 12 16 377 0.326 0.043 0.03 <--why? how to get rid of it?
