ntptrace doesn't show ntp server names
Last modified: 2010-03-19 05:54:04 EDT
On Fedora 2 test 3, I got hjl@gnu-64b gnu-20]$ /usr/sbin/ntptrace gnu-64b.sc.intel.com: stratum 16, offset 0.000000, root distance 0.000000 I am expecting something like bash-2.05b$ ntptrace localhost.localdomain: stratum 2, offset 0.000047, synch distance 0.03241 ntp-nasa.arc.nasa.gov: stratum 1, offset -0.002047, synch distance 0.00089, refid 'GPS'
Apparently, the new one works differently from the old one where the new one will output gnu-64b.sc.intel.com: stratum 16, offset 0.000000, root distance 0.000000 if the machine isn't synced yet and old one will wait.
I have 2 machines on the same network. One is running EL 3 U2 and the other is running EL 4 A3. On EL 3 U2, I got [hjl@gnu-20 kernel-EL]$ ntptrace gnu-20.sc.intel.com: stratum 4, offset 0.000000, synch distance 0.06349 sc127a-hsrp-140.sc.intel.com: stratum 3, offset 0.006058, synch distance 0.01227 scbc.wan.intel.com: stratum 2, offset 0.000957, synch distance 0.00774 scntpsrv.wan.intel.com: *Timeout* On EL 4 A3, I got [hjl@gnu-64 hjl]$ ntptrace gnu-64.sc.intel.com: stratum 4, offset -0.040207, root distance 0.007428 143.183.140.251: timed out, nothing received ***Request timed out [hjl@gnu-64 hjl]$ host 143.183.140.251 251.140.183.143.in-addr.arpa domain name pointer sc127a-hsrp-140.sc.intel.com. I believe EL 4 A3 is synced with sc127a-hsrp-140.sc.intel.com. It is just that ntptrace doesn't show it.
is sc127a-hsrp-140.sc.intel.com a router or s.th. like that?
sc127a-hsrp-140.sc.intel.com is the NTP server on the subnet.
yes, I know, but which kind of machine is this? a linux PC?
I have no idea what kind of machine sc127a-hsrp-140.sc.intel.com is. FWIW, ntptrace in RHEL 3 U3 works fine with it.
The new ntptrace in RHEL 4 is a perl script, which uses "ntpq". I got these on RHEL 3 U3: [hjl@gnu glibc]$ ntpq sc127a-hsrp-140.sc.intel.com ntpq> rv sc127a-hsrp-140.sc.intel.com: timed out, nothing received ***Request timed out ntpq> [hjl@gnu glibc]$ ntptrace sc127a-hsrp-140.sc.intel.com sc127a-hsrp-140.sc.intel.com: stratum 3, offset 0.004291, synch distance 0.02068sccc.wan.intel.com: stratum 2, offset 0.004002, synch distance 0.01994 chntpsrv.wan.intel.com: In the ntpq man page on RHEL 4, there are The ntpq utility program is used to query NTP servers which implement the recommended NTP mode 6 control message format about current state and to request changes in that state. Since this functionality is a recommended feature, a compliant ntp server may not implement/enable it.
so bug or rfe?
It is a regression from RHEL 3.
Ok, posted: http://bugzilla.ntp.org/show_bug.cgi?id=364
Back in assigned, as we're no longer awaiting information.
As RHEL-4.9 is the last update for RHEL-4, which should address only security, performance and critical issues, I'm closing this bug as WONTFIX. If you are still experiencing this issue with RHEL-5, please reopen it against RHEL-5. If this issue is critical for you, please contact Red Hat support.
