What software is needed and available?

Where to get all the needed software?

Distribution

• Around the world: Red Hat 7.2 (Glibc-2.2 based) or newer

Newer Kernel

• See relating information in the HowTo further on

Glibc-2.1/2.2

• Should now included in a current Linux distribution

Several IPv6 applications

• See relating information in the HowTo further on

Network configuration tools

• See relating information in the HowTo further on

Remaining software

• See relating information in the HowTo further on

Installation decissions - Quick IPv6-enabling HowTo

Type of host

• General
• To do:
• Apply all available updates on your installation to make your host more secure
• Disable all not used network services to prevent future possible attacks
• Client on a LAN which has already IPv6 support (means a box sends router advertisements out)
• To read:
• Normally nothing
• To do:
• Add following line in /etc/sysconfig/network: NETWORKING_IPV6="yes"
• Restart networking (or reboot)
• Interface should be automagically configured with an IPv6 address regarding to the received router advertisement
• Client on a LAN, no local IPv6 support available
• To do:
• Ask your network administrator whether it is allowed and possible to get an IPv6-in-IPv4-tunnel to your client
• To read:
• Network configuration, especially tunnel parts (normal or 6to4)
• To do:
• Dedicated tunnel configuration (not so easy)
• Server on a LAN which has already IPv6 support
• To be:
• Server administrator
• To do:
• Ask your network administrator about a fixed IPv6 address and a DNS entry for it
• To read:
• Network configuration, especially how to configure fixed addresses
• Depending on services which should be offered over IPv6: the apps pages
• IPv6-Firewalling
• To do:
• Dedicated interface configuration (easy)
• Server on a LAN, no local IPv6 support available
• To be:
• Server administrator
• To do:
• Look for reasons, why installing a server without any clients on a not IPv6 enabled LAN
• Tunnel endpoint
• To be:
• Network administrator
• To do:
• Ask the CSO about your wishes and wait for the OK (perhaps extend the security policy)
• Discuss with CSO and firewall administrators about where to place the tunnel endpoint and how to protect the tunnel endpoint itselfand the internal network
• Look for a tunnel provider
• To read:
• Network configuration, especially tunnel parts
• IPv6-Firewalling
• To do:
• Dedicated tunnel configuration (not so easy)
• If tunnel should used by clients: setup of router advertisement daemon

In which sequence should the software be installed?

Primary Sequence Order:

1. Basic Software
• Linux distribution
• IPv6 ready kernel
2. Important Applications
• IPv6 ready configuration tools
• IPv6 ready applications
• IPv6 ready debugging tools
3. IPv6 start-up configuration scripts
4. Additionals
