[Bug 1339932] Re: iptables -j LOG fails on 12.04 kernel 3.4.4-guest

 

Upgrading to 12.04.5 and installing the Trusty kernel fixed the problem:

aptitude safe-upgrade
apt-get install --install-recommends linux-generic-lts-trusty

Title:
  iptables -j LOG fails on 12.04 kernel 3.4.4-guest

Status in “iptables” package in Ubuntu:
  New

Bug description:
  iptables was working fine until I did an upgrade to a new kernel
  version.  Now it is impossible to load my firewall rules using
  iptables-restore.  The iptables-restore program croaks when trying to
  load the rules.

  While the error is reported on the line associated with the "COMMIT"
  statement, it appears that it is really failing when the "-j LOG"
  option is used.  If I eliminate the "-j LOG" option on statements, it
  seems to work normally (like it did before).

  When I run lsmod, there is no "xt_LOG" or "ipt_LOG" module present. I
  cannot find the "xt_LOG.ko" or "ipt_LOG.ko" file anyplace, so I cannot
  load them manually.

  Not sure if this is a kernel bug or an iptables bug, but since it
  makes it impossible to load my firewall rules and leaves my system
  wide open, it's definitely a security issue.
