perfSONAR User Q&A and Other Discussion

[Murilo Vetter <>]

Hi Antoine,

So, I was trying to upgrading the Debian SO from 7 to 9.

These servers are ours MonIPE servers that I were trying to check if it would be possible to upgrade the system and use the perfsonar bundle.

The perfsonar packages that I was trying to install were:

    - numactl
    - snmpd
    - pps-tools
    - setserial
    - stress-ng
    - perfsonar-testpoint
    - unattended-upgrades
    - perfsonar-toolkit-servicewatcher
    - perfsonar-toolkit-ntp
    - perfsonar-toolkit-security
    - perfsonar-toolkit-sysctl

The NTP configuration is as follows:

# cat /etc/ntp.conf

--
# /etc/ntp.conf, configuration for NTP
# by default act only as a basic NTP client
restrict -4 default nomodify nopeer noquery notrap
restrict -6 default nomodify nopeer noquery notrap
# allow NTP messages from the loopback address, useful for debugging
restrict 127.0.0.1
restrict ::1
logfile /var/log/ntpd
driftfile /var/lib/ntp/ntp.drift
statsdir  /var/lib/ntp/
statistics loopstats peerstats clockstats
filegen loopstats file loopstats type day enable
filegen peerstats file peerstats type day enable
filegen clockstats file clockstats type day enable

# You should have at least 4 NTP servers

server chronos.es.net iburst   # ESnet - New York, NY USA

server ntp-gatech.usno.navy.mil iburst   # Naval Observatory - GATech

server owamp.atla.net.internet2.edu iburst   # Internet2 - Atlanta, GA USA

server owamp.chic.net.internet2.edu iburst   # Internet2 - Chicago, IL USA

server owamp.losa.net.internet2.edu iburst   # Internet2 - Los Angeles, CA USA

The strange thing is that the installation does not complete its execution. It stucks for hours.

Could it be some compatibility problem by doing "apt-get dist-upgrade" or something like that?

Regards,

Hi Murilo,

Can you tell us a bit more about your setup?  Are you installing this packet as an additional one to the perfsonar-testpoint bundle or as part of the perfsonar-toolkit?

Do you manage the list of NTP servers in /etc/ntp.conf in some other automated ways with some configuration management tools?  How many servers do you currently have listed in the ntp.conf file?  Can you check you have at least 4 reachable NTP servers listed there?  And by reachable, I should probably say 'pingable'.

Thanks,

Antoine.

Hi,

I don't think so. It occurs when I install the package perfsonar-toolkt-ntp.

The system that I am trying to install is:

--

# cat /etc/debian_version
9.4

# uname -an
Linux monipe-bc 4.9.0-6-amd64 #1 SMP Debian 4.9.88-1+deb9u1 (2018-05-07) x86_64 GNU/Linux

--

The installation stucks at:

--

# apt install perfsonar-toolkit-ntp

Could it be that UDP port 123 used by NTP is somehow blocked on
your network?
