Description Dax Kelson 2004-02-16 07:37:54 UTC

Description of problem:

This problem has existed ever since RHL8/9. I teach Linux classes and
students get bitten by this all the time.

When system|redhat-config-network is first launched it creates files
in the /etc/sysconfig/networking/profiles/default/ directory. If you
then *save* and exit the tool, it hard links them to the
/etc/sysconfig/network-scripts files.

If a person launches the tool and then exits (without making changes
and saving), then the "default" profile interface files are
out-of-synce with the files in /etc/sysconfig/network-scripts/.

The "search path" for ifup/ifdown has the default profile before the
/etc/sysconfig/network-scripts directory, so when changes are made in
the "standard" location with a text editor the changes don't seem to
take effect.

This can be easily observed.

On a freshly installed system I launch system|redhat-config-network.

# ls -i /etc/sysconfig/network-scripts/ifcfg-eth0
20772 /etc/sysconfig/network-scripts/ifcfg-eth0

# ls -i /etc/sysconfig/networking/profiles/default/ifcfg-eth0
16879 /etc/sysconfig/networking/profiles/default/ifcfg-eth0

Note how the inode numbers are different. The files are different.

Now if I do File -> Save, and then check the inode numbers:

# ls -i /etc/sysconfig/network-scripts/ifcfg-eth0
16879 /etc/sysconfig/network-scripts/ifcfg-eth0

# ls -i /etc/sysconfig/networking/profiles/default/ifcfg-eth0
16879 /etc/sysconfig/networking/profiles/default/ifcfg-eth0

You can see it is the same file.

When I lecture my classes I currently tell my students, "if you decide
to launch the system|redhat-config-network utility to see what it
looks like make sure you *save* (even though they haven't changed
anything) otherwise your /etc/sysconfig/network-scripts will be
ignored by ifup/ifdown".

Please fix system|redhat-config-network. I can think of a couple ways.

1) Don't create the default profile files until a "save" is done. Then
make them as hard links from the begining. This seems best to me as it
seems a little odd for the tool to perform *any* changes in /etc just
by merely launching it.

2) Create the files as hard links from the very begining.

This is wrong... the initscripts should not look in
/etc/sysconfig/networking!!

reassigning

Are you sure? Doesn't that then break network profiles?

search path for:
# ifup $DEV
is:
/etc/sysconfig/networking/profiles/$CURRENT_PROFILE/ifcfg-$DEV
/etc/sysconfig/networking/profiles/default/ifcfg-$DEV
/etc/sysconfig/network-scripts/ifcfg-$DEV

Seems they *have* to look in /etc/sysconfig/networking.

They don't.

Comment 4 Dax Kelson 2004-09-04 19:10:15 UTC

The original problem 

"If a person launches the tool and then exits (without making changes
and saving), then the "default" profile interface files are
out-of-synce with the files in /etc/sysconfig/network-scripts/."

Is fixed. 

I tested rawhide from today (FC2test3??).
