arptables v0.0.8: no hln defined

[Claus Wimmer]

Hello,

I am trying to build up a gateway cluster according to the example in
the iptables manpage (see cluster extension). But I am not able to use
the arptables command successfully:


host1:/ # arptables -A OUT -o intern --arhln 6 -j mangle --mangle-hw-s
01:00:5e:11:11:11
arptables v0.0.8: no hln defined
Try `arptables -h' or 'arptables --help' for more information.
host1:/ #


Here comes some system information:

host1:/ # lsmod | grep arp
arpt_mangle             2760  0
arptable_filter         4168  0

Do I miss something or is there a problem with arptables?


Thanks in advance

That appears to be a bug in arptables, it seems to expect a mask
for arhln, but doesn't assume a full match in case none is specified.

This is an unofficial version which I think orginates at RedHat, so
you should talk to whoever maintains this.
