Main

Testing IPv6 support and dualstack networking can be very tricky. The purpose of this document is to provide a live resource on testing situations arising from existance and usage of two network layer protocols.

How to prepare test environment:

How to test different types of packages:

Known issues:

Packages

Packages that are expected to play well with IPv6

Following packages play more or less well with IPv6. You can still expect minor issues including delays when configuration of one of the protocols doesn't work as expected. Those packages are still to be tested.

Network configuration:

  • dhcp – Dynamic host configuration protocol software
  • iproute – Advanced IP routing and network device configuration tools
  • NetworkManager – Network connection manager and user applications
  • dnssec-trigger – NetworkManager plugin to update/reconfigure DNSSEC resolving

Server software:

  • bind – The Berkeley Internet Name Domain (BIND) DNS (Domain Name System) server
  • dnsmasq – A lightweight DHCP/caching DNS server
  • httpd – Apache HTTP Server
  • openssh – An open source implementation of SSH protocol versions 1 and 2

Other:

  • curl – A utility for getting files from remote servers (FTP, HTTP, and others)
  • cyrus-imapd – A high-performance mail server with IMAP, POP3, NNTP and SIEVE support
  • c-ares – A library that performs asynchronous DNS operations
  • firefox – Mozilla Firefox Web browser
  • libssh2 – A library implementing the SSH2 protocol
  • iptables – Tools for managing Linux kernel packet filtering capabilities

Packages with broken or incomplete IPv6 support

Core system:

  • avahi – Local network service discovery
    • IPv6 turned off by default
    • nss-mdns doesn't do IPv6LL due to glibc limitations
  • glibc – The GNU libc libraries

Core tools:

Development:

Packages that are intended for IPv4-only operation

Following packages do not need any IPv6 testing as they contain IPv4 specific tools.

  • arptables
  • arpwatch

Notable packages to be tested for IPv6 support

Following packages weren't categorized yet but are considered important enough to be checked for IPv6 support. Please extend the list with other high visibility packages.

Core system:

  • abrt – Automatic bug detection and reporting tool
  • anaconda – Graphical system installer
  • apr – Apache Portable Runtime library
  • busybox – Statically linked binary providing simplified versions of system commands

    • IPv6 in /etc/resolv.conf
    • IPv6 on bridged networks
  • dracut – Initramfs generator using udev
