can't (re)start ntpd server on fc3. ie. after:
---------------------------------------
# /etc/init.d/ntpd restart
Shutting down ntpd: [FAILED]
ntpd: Synchronizing with time server: [ OK ]
Starting ntpd: [ OK ]
# ps axu|grep ntp
root 23165 0.0 0.0 4992 688 pts/0 S+ 14:40 0:00 grep ntp
---------------------------------------
after i found it just test it:
---------------------------------------
# ntpd -n -u ntp:ntp -p /var/run/ntpd.pid
Segmentation fault
---------------------------------------
so i debug ntpd itself:
---------------------------------------
