[Bug 1186662] Re: isc-dhcp-server fails to renew lease file

 

Can someone please confirm my understanding of this issue?

a) Ubuntu has configured dhcpd to drop root privileges
b) Ubuntu has added logic to dhcpd.conf to force the ownership of dhcpd.leases to root:root
c) Ubuntu is managing the ownership (and permissions?) of the directory in which dhcpd.leases lives, keeping it as root:root

We at ISC are not really clear what we're supposed to do with this.

Thanks,
Brian Conry

Title:
  isc-dhcp-server fails to renew lease file

Status in “isc-dhcp” package in Ubuntu:
  Triaged

Bug description:
  After raring upgrade, the dhcp server fails to renew lease file when
  it tries to (about every hour).

  The syslog says:
  dhcpd: Can't create new lease file: Permission denied

  It looks like a permission problem, because

  # chown -R dhcpd:dhcpd /var/lib/dhcp

  the above command temporarily solves the issue, until dhcpd is
  restarted: at that time, the ownership of the directory and the lease
  file is set back to root:root.
