Red Hat Bugzilla – Bug 10936
Suggestion: 'ifup-pre' and 'ifdown-pre'
Last modified: 2014-03-16 22:13:29 EDT
I would like to suggest creating hooks for "pre" analogues of the currently
existing 'ifdown-post' and 'ifup-post' scripts, and then for the
'ifup-local' and 'ifdown-local' scripts one can plug in. I am a dialup
user, and use the dhs.org static hostname -> mutable IP address mapping
service because Kerberos (used on MIT/Athena) requires it. Kerberos does
an "idiot-check" of the host identification by a
I have my system do some acrobatics on both device up and down, but also
need hooks before the device state is changed in either direction. For
example, before I shutdown my external networking, I must currently run a
script manually to disable my DNS entry at dhs.org. This is not a problem
on startup, as I can just include that action in 'ifup-local' but
'ifdown-local' is executed after the device is disabled.
I could hack my scripts to rectify the problem, but it is certainly
non-standard and I cannot share my solution with others who have rapidly
changing network configuration without rolling my own 'initscripts' package
-- this is uncomfortable, give how critical this component is!
If you wish, I can implement the hack and submit a patch, but it would
require a change in the naming convention of the local plugin scripts.
There is an ifup-pre-local in Red Hat Linux 7.0.
In this bugreport, the resolution was that 'ifup-pre' was added in 7.0. I would
like to request that 'ifdown-pre-local' be added. I have some network
de-registration to do before the interface is taken down, and I currently have
to hack the initscripts to do this.
Sure, will be in 5.76-1.
