Description Christopher Aillon 2004-07-27 13:56:34 EDT
Description of problem:
ntpd: Opening firewall for input from port 123[  OK  ]
ntpd: Opening firewall for input from clock.redhat.com port
123/etc/init.d/ntpd:  line 169:  9481 Segmentation fault      iptables
-I $FWCHAIN -m udp -p udp -s $ server/32 --sport 123 -d 0/0 --dport
123 -j ACCEPT
ntpd: Synchronizing with time server:                      [  OK  ]
Starting ntpd:                                             [  OK  ]

Version-Release number of selected component (if applicable):
# rpm -q ntp

How reproducible:

Steps to Reproduce:
1. service ntp start
Actual results: Segfault.

Expected results: Not a segfault :-)

Additional info:

I noticed that system-config-securitylevel had the firewall enabled. 
Disabling the firewall causes ntp to load normally.
Comment 1 Harald Hoyer 2004-07-28 03:19:11 EDT
this is iptables, which segfaults
Comment 2 Thomas Woerner 2004-08-02 10:55:33 EDT
Can you give me the glibc and iptables version by 'rpm -q <rpm>' and
your fireall configuration (/etc/sysconfig/iptables*).
