Public bug reported:
Binary package hint: linux-source-2.6.20
My Firewall script that previously run fine in Edgy, now fails in Feisty,
I have isolated the lines involved and run it on 3 separate Feisty machines to
confirm it fails consistently.
Run the following script to reproduce the problem, removing any one of the
lines will not produce the error,
and also changing the nlgroup to 31 (or lower) will not produce the error, so
it is a particular combination.
the last line in the script gives the following error
iptables: Too many levels of symbolic links
I have included an strace and versions below the script, if you need any
further info, please let me know.
Cheers
Brin
