Description of problem:
I set up a PPP connection in redhat-network-config, and it did not work from
either redhat-network-config or ifup. I think it shouldn't be hard to fix this
problem, but I may need suggestions from someone who is more familiar with the
philosophy behind the network scripts before I can code up a patch. (Or maybe I
just need to try again with a Red Hat release and see what happens in a working

Note that I'm not at all sure whether this is a redhat-config-network problem or
an initscripts problem.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Set up a PPP connection in redhat-config-network.
2. Save your settings.
3. Try to activate it.

Actual Results:  Failed to activate ppp0 with error 28

Expected Results:  A PPP connection should have been established.

Additional info:

"ifup UCI_lifeline" (UCI_lifeline is the name of my PPP config in
redhat-config-network) eventually does this:
exec /etc/sysconfig/network-scripts/ifup-ppp

and that eventually does this:
exec /sbin/ppp-watch ppp0 ''

and ppp-watch eventually (does something that) spits out the error 28 error message.

If I manually run the following command, I get a successful connection:
/sbin/ppp-watch UCI_lifeline

If you need any of my config files, just ask and I'll attach them or whatever.

Comment 1 Bill Nottingham 2003-06-23 14:53:16 UTC
Yeah, this is an issue with how it's reading profiles. Can you attach

This is my PPP connection.

/etc/sysconfig/network-scripts/ifcfg-lo is a symlink to

I've attached all of /etc/sysconfig/network-scripts/ifcfg-* now. (I someitmes
connect this machine to Ethernet networks and sometimes use dialup, thus the
presence of ifcfg-eth0 as well as ifcfg-UCI_lifeline.) If you need any more info
or whatever, just ask.

Comment 6 Barry K. Nathan 2003-06-25 04:46:13 UTC
As of initscripts-7.25-1:
"ifup UCI_lifeline" now ends with this instead:
exec /etc/sysconfig/network-scripts/ifup-ppp ifcfg-UCI_lifeline

But that still leads to:
exec /sbin/ppp-watch ppp0 ''

And that still fails with error 28.

patch against initscripts-7.28-1 to attempt to fix this bug

I don't know whether the bug is in ifup-ppp or in ppp-watch. This patch blindly
assumes the former.

This gets me to the point that redhat-config-network will dial up, and appear
to freeze at "Activating network device UCI_lifeline, please wait...". (Is
r-c-n waiting for ppp-watch to exit? I don't know how previous RHL released
worked in this regard, but ppp-watch doesn't exit on its own nowadays.) I'm
going to see what happens when I click "Cancel", but first I want to get this
attachment into Bugzilla.

Comment 8 Barry K. Nathan 2003-07-30 07:34:54 UTC
Ok, clicking "Cancel" changes the message to "Cannot activate network device
UCI_lifeline!" but keeps the dialog box on the screen and keeps the network
connection up.

Comment 9 Barry K. Nathan 2003-07-30 07:48:09 UTC
Clicking "OK" dismisses the dialog box, but r-c-n still seems to think the PPP
connection isn't active ("Activate" is still clickable, while "Deactivate" is
grayed out). /sbin/ifconfig shows that the PPP connection is clearly up. r-c-n
is still clueless after I quit it and start it up again.

At some point during my last few comments, ppp-watch died but pppd lived on.

Comment 10 Barry K. Nathan 2003-07-30 07:52:02 UTC
[root@i5000e network-scripts]# /sbin/ifdown ppp0

It looks like nothing short of actually killing pppd is going to terminate my

Comment 12 Bill Nottingham 2003-09-15 05:36:24 UTC
This should be fixed in initscripts-7.32-1; it requires changes to ifup-ppp,
ifdown-ppp, and ppp-watch.

Comment 13 Bill Nottingham 2003-09-15 05:42:07 UTC
7.33-1, sorry.
