As a taste of what is to come in nfs-utils, and to garner comments on the
work to date, here is a set of eight patches that implement efficent
support for rpcbind v2, v3, and v4 over AF_INET and AF_INET6, and then
make use of this new implementation to update the showmount command to
support IPv6 and use the new rpcbind versions.
The plan is to use this implementation in the [u]mount.nfs[4] commands
as well.
To try it out, you can apply these patches to the latest nfs-utils. If
you want IPv6 support for the showmount command, in addition to the new
rpcbind versions, configure nfs-utils with "--enable-ipv6".
If you are time-limited, please have a look at just the first two patches.
These introduce the new getport() implementation.
For the curious, a full set of client-side nfs-utils patches (minus IPv6
support in rpc.statd) is available in the usual place:
