Re: iptables is complaining with bogus unknown error 18446744073709551615

[Maurice Volaski <mvolaski@aecom.yu.edu>]

At least since 2.6.1.16.1, many calls to iptables no longer function 
at least under 64-bit x86, presumably due to a bug in the netfilter 
kernel code.

The problem is still present in 2.6.17-rc2.

The error from iptables is
iptables: unknown error 18446744073709551615

Examples of rules that give the error are

1) iptables -A INPUT -i bond0 -s 129.98.90.0/24 -p tcp --dport 548 -j ACCEPT
2) iptables -A INPUT -i bond0 -s 129.98.90.101/32 -p tcp --dport 497 -j ACCEPT
3) iptables -A INPUT -i bond0 -s 129.98.90.227/32 -p tcp --dport 22 -j ACCEPT

Example of a rule that does not give the error:
1) iptables -A INPUT -i bond0 -p ICMP --icmp-type echo-request -s 
129.98.90.13/32 -j ACCEPT

The computer is using IPv4 and not IPv6, which has not been compiled into the
kernel.

iptables is version 1.3.5.
