[Planetlab-users] NTP daemon

[Markus Gnauck]

Hello PlanetLab Users!

I installed ntp on some of my project's nodes. Unfortunately when  
trying to run the ntp service it seems to crash immediately upon  
startup.

$ sudo yum install ntp
..works as expected..

$ sudo /etc/init.d/ntpd start
Starting ntpd:                                             [  OK  ]

$ /etc/init.d/ntpd status
ntpd dead but pid file exists

I tried to search for the problem, with some sources suggesting to  
delete /var/run/ntpd.pid and restarting ntpd. As anticipated that did  
not help much. The results are still as depicted above. (To my  
knowledge the configuration file ntpd.conf seems fine though.)

When tracing the problem my tutor came up with the following output  
which strongly seems like a permission issue:

The problem appeared on all the nodes that I've considered. I'm kind  
of at a loss right now. Do you have any suggestions, pointers or help  
to solve my problem?!
Please let me know if I better direct the question to a different  
source of support for issues regarding PlanetLab.

Thanks in advance! Cheers,
