[Bug 1029361] Re: 'attempts' DNS option has no effect

[Thomas Hood]

Resolvconf seems to be working correctly: it adds the "tail" file to the
dynamic resolv.conf file.

** Package changed: resolvconf (Ubuntu) => eglibc (Ubuntu)

** Summary changed:

- 'attempts' DNS option has no effect
+ resolv.cofn 'attempts' option has no effect

** Summary changed:

- resolv.cofn 'attempts' option has no effect
+ resolv.conf 'attempts' option has no effect

Title:
  resolv.conf 'attempts' option has no effect

Status in “eglibc” package in Ubuntu:
  New

Bug description:
  From man(8) resolvconf:

         /etc/resolvconf/resolv.conf.d/tail
                File  to  be appended to the dynamically generated resolver con‐
                figuration file.  To append nothing, make this  an  empty  file.
                This  file is a good place to put a resolver options line if one
                is needed, e.g.,

                    options inet6

  
  I tried to stick in some options to influence the behavior when my 12.04 system has no network connectivity:

  Looking at man(5) resolv.conf, I added this to
  /etc/resolvconf/resolv.conf.d/tail:

  
  options timeout:2 attempts:1

  
  After reloading the network, I can see both of these options in /etc/resolv.conf:

  # Dynamic resolv.conf(5) file for glibc resolver(3) generated by resolvconf(8)
  #     DO NOT EDIT THIS FILE BY HAND -- YOUR CHANGES WILL BE OVERWRITTEN
  nameserver 2001:610:1:800a:192:87:106:106
  nameserver 2001:610:188:140:145:100:188:188
  search terena.org
  options timeout:2 attempts:1

  
  The configured timeout seems to work, but the 'attempts' doesn't.

  Also putting in those values on their own on a single has the same
  result: 'timeout' value gets picked up, 'attempts' doesn't.

  
  FYI /etc/network/interfaces looks like this:

  
  # This file describes the network interfaces available on your system
  # and how to activate them. For more information, see interfaces(5).

  # The loopback network interface
  auto lo
  iface lo inet loopback

  # The primary network interface
  auto eth0
  iface eth0 inet static
          address 192.87.30.17
          netmask 255.255.255.192
          gateway 192.87.30.1

  # IPv6 static address
  iface eth0 inet6 static
          address 2001:610:148:dead::666
