#72548: inetutils @2.6: (g)ifconfig command is broken and should probably be
disabled
--------------------+-------------------------
Reporter: jleroy | Owner: Schamschula
Type: defect | Status: assigned
Priority: Normal | Milestone:
Component: ports | Version: 2.10.7
Keywords: | Port: inetutils
--------------------+-------------------------
The ifconfig command provided by inetutils port simply doesn’t work (at
least on macOS Sequoia): no IPv6 support and a lot of other missing
information.
{{{
$ which -a ifconfig
/opt/local/libexec/gnubin/ifconfig

As this is a low-level macOS command, GNU’s version will probably never
work correctly on macOS anymore and may potentially harm any user who
added `/opt/local/libexec/gnubin` to its shell path.
Same thing applies to GNU’s `hostname` command which convert the hostname
to lowercase which can potentially breaks things:
{{{
$ which hostname
/opt/local/libexec/gnubin/hostname
/bin/hostname
$ /opt/local/libexec/gnubin/hostname -f
macbook-pro-de-jonathan.local
$ /bin/hostname -f
MacBook-Pro-de-Jonathan.local
}}}
IMHO both commands should be disabled.
