Description jbowman 2002-05-17 18:34:39 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.0.0+) Gecko/20020514

Description of problem:
/etc/sysconfig/network-scripts/ifup for 7.2 and 7.3 use the 'ip' command to
build network devices instead of the older 'ifconfig'. Unfortutunately,
/etc/sysconfig/network-scripts/ifup-aliases is still building alias interfaces
using 'ifconfig'. Could ifup-aliases get upgraded to match the main ifup script?

Also in that vein, /etc/sysconfig/network-scripts/ifup doesn't support the
concept of a configurable scope for an address. Being able to specify a
"SCOPE=local" directive in ifcfg-eth0:x alias files, for example, would be of
great use when configuring a server with a large number of aliased interfaces
that you don't want to be part of the normal address pool that can be bound to
with 'ANY' on an outgoing connection.

Comment 1 jbowman 2002-05-17 18:37:49 UTC
Err, that should be 'SCOPE=host' in my example, but you get the idea...

Comment 2 Dr. Stephan Wonczak 2002-10-17 13:51:24 UTC
Also, it would be really useful to be able to specify ONBOOT=no for the aliased
interfaces. This would allow you to preconfigure aliases identically on multiple
machines to be brought up when necessary (for migrating services for example)

It's so old... still issue persists??

Comment 5 Dale Stimson 2010-03-18 01:43:44 UTC
I found this bug because I ran into a situation where ifconfig (with respect to an infiniband interface) said:

$ ifconfig ib0
Ifconfig uses the ioctl access method to get the full address information, which limits hardware addresses to 8 bytes.
Because Infiniband address has 20 bytes, only the first 8 bytes are displayed correctly.
Ifconfig is obsolete! For replacement check ip.

And that motivated me to rewrite ifup-aliases to use /sbin/ip instead of ifconfig.  I have *lightly* tested the new file.  (It brings up the aliases OK on my system, but I am sure there are untested code paths).

Besides the changes directly related to changing from ifconfig to /sbin/ip, I have also done some variable initialization and changed some "${xxx}" to "${xxx:-}".  This is because (just for testing) I had a "set -u" present to detect undefined variables.

For a "freshen" I replaced a single invocation of
    /sbin/ifconfig $DEVICE netmask $NETMASK broadcast $BROADCAST;
with /sbin/ip calls to flush the address and then re-add it as there seemed to be no directly corresponding /sbin/ip functionality.

The base version of ifup-aliases came from initscripts-9.02.1-1.i686 as is current for Fedora 12.

File to be attached to this bug: ifup-aliases.patch

I will also attach a straight-up version of ifup-aliases for easy reference.

While readin up on bug #195365 and bug #195353, I've grepped through initscripts-9.20.1-1.fc14 -- lots of ifconfig in ifup-*

See also https://www.linuxfoundation.org/collaborate/workgroups/networking/etcnet -- maybe let's go with innovation instead of age-old crap which isn't easily fixable due to ifconfig-era design decisions wrt ifcfg-* format?

/etc/net represents a new approach to Linux network configuration tasks.

Inspired by the limitations of traditional network configuration subsystems,
/etc/net provides builtin support for configuration profiles, interface name
management, removable devices, full iproute2 command set, interface
dependencies resolution, QoS and firewall configuration frameworks.

/etc/net provides support for the following interface types: Ethernet, WiFi
(WEP), IPv4/IPv6 tunnels, PSK IPSec tunnels, VLAN, PLIP, Ethernet bonding and
bridging, traffic equalizer, Pent@NET, Pent@VALUE, SkyStar-2, TUN/TAP,
OpenVPN TUN/TAP, OpenSSH TUN/TAP, usbnet and PPP. 

Due to its modular structure, support for new interface types can be added without overall design changes.


It's used by ALTLinux since aug-2004

Comment 11 Robert Scheck 2011-03-15 20:08:32 UTC
Nevertheless, /etc/net is not a drop-in replacement for what we have now.

Comment 12 Michael Shigorin 2011-03-16 07:46:14 UTC
Definitely.  It's not maintaining bug compatibility like ifcfg-* (doing multiple IPs per interface with numbered variables is a syntax/parser horror), but this clearly has a price to pay in docs, habits, 3rd party tools and archived advice.

/etc/net was successfully introduced as an alternative networking configuration subsystem in ALT Linux and for a release or so there both net-scripts (distilled from initscripts) and etcnet were available (though conflicting over /etc/rc.d/init.d/network, of course).

Comment 13 Albert Strasheim 2011-09-05 08:38:16 UTC
Any chance we could get this fixed? This bug is headed for it's 10th birthday.

Comment 14 joshua 2012-04-25 23:00:02 UTC
Yes please... even if need a big overhaul, let's do it!

Comment 15 Bill Nottingham 2012-04-26 16:10:30 UTC
ifup-aliases uses ip as of a F-16 update.
See git commit 59a9d2b792ff218f5ccd8e4e8c0ffe6f76efb13a.
