dhcp3 was superceded by isc-dhcp between lucid and precise and therefore is not available under any supported ubuntu release. Marking the task dhcp3 as "Won't Fix".

This fails to drop privileges of root-group and does not initialize the groups properly. One can test this by adding: on commit { execute("/usr/local/bin/dhcp_group_test"); } to /etc/dhcp3/dhcpd.conf, and then write /usr/local/bin/dhcp_group_test to log the output of "id" to some file. (You may wish to turn apparmor off for this test, but it can be done with it as well). The output should read: uid=112(dhcpd) gid=120(dhcpd) groups=0(root) This means that dhcp will retain the root-group privileges and is missing other groups that a user may have possibly defined for it. The fix would be to use either initgroups() or setgroups() function properly in drop_privileges(). Doing this should also fix this bug: https://bugs.launchpad.net/ubuntu/+source/dhcp3/+bug/341817 This is: Description: Ubuntu 10.04.1 LTS Release: 10.04 dhcp3-server: Installed: 3.1.3-2ubuntu3 Candidate: 3.1.3-2ubuntu3 Version table: *** 3.1.3-2ubuntu3 0 500 http://mirror.opinsys.fi/ubuntu/ lucid/main Packages 100 /var/lib/dpkg/status To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/dhcp3/+bug/727837/+subscriptions -- Mailing list: https://launchpad.net/~touch-packages Post to : touch-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~touch-packages More help : https://help.launchpad.net/ListHelp
