Our project uses a bunch of open source packages. I’ve been looking through them and this seems to be the current state:

• Linux Kernel: Good to go in both 2.4 and 2.6
• OpenPegasus CIM Broker: IPV6 support is underway, but not yet implemented.
• SBLIM SFCBD IPV6 Support is built in, based on a compile time switch
• OpenIPMI: IPMI Tool won’t accept a valid IPv6 address. This is a slightly different code source than the rest of the project, so it doesn’t mean that the rest of it won’t support IPv6.
• OpenWSMAN
• OpenSSL: Claims to be agnostic of the IP level. Since Open SSH is build on OpenSSL, and OpenSSH works, it works for at least a subset of it’s functionality.
• OpenSSH: Connecting via IPv6 Works Confirmed for both ssh and scp.  scp is a pain.
• OpenSLP: Seems to have IPv6 support, but it isvery recent.  It requires IPv6 multicast support.  Multicast has often been an after thought in switch implementations, so IPv6 multicast may have issues in the future.
