Description Edson Da Luz 2004-02-20 22:15:47 UTC 
Description of problem:
"iptables-restore" crashes with a "segmentation fault" error when used
with option "-c" and a configuration file created manually. After
several tests I found out that the problem happens when the
configuration file doesn't have the packet/byte counters (e.g. [0:0])
included with the chain names (lines beginnibg with ":"). The counters
must be included in the file in order for "iptables-restore -c" to
work properly. If "iptables-restore" is used without "-c", then the
counters can be omitted from the file.

Version-Release number of selected component (if applicable):
iptables-1.2.7a-2 (original Red Hat 9 distribution)

How reproducible:

Steps to Reproduce:
1. Use iptables-save to create a configuration file.
2. Edit this file and remove all packet/byte counters (e.g. [0:0])
from the file.
3. Load the same file with "iptables-restore -c".
  
Actual results:
"iptables-restore -c" crashes.

Expected results:
"iptables-restore -c" should work properly I think.
