R: Check_ntp

[Bill Jacqmein]

ntptrace on the linux system should help in figuring out where ntp is breaking.
Ive had a problem with the ntp.drift file having a bad value in it
causing the ntp service to flap between working correctly and the "No
suitable peer server found" error. The solution was to delete the
ntp.drift file and let it be recreated.
