Description of problem:
After configuring ISDN connection with NEAT, and clicking 'Activate' button, the
'Network device activating...' just hangs there (the interface is up and running
fine). When set to activate automatically on boot, the boot sequence hangs on
'Bringing up interface ippp0' too.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Configure ISDN dialup connection with NEAT
2.Set to activate on boot, or click 'Activate' button manually.
Actual Results: Boot sequence hangs, or 'Network device activating...' window
Expected Results: Boot sequence completes successfully, or 'Network device
activating...' window disappears when the device has become active.
I solved this problem by adding an '&' character to line 329 of
/etc/sysconfig/network-scripts/ifup-ippp (i.e. backgrounding the invocation of
-ipppd $options >/dev/null 2>&1
+ipppd $options & >/dev/null 2>&1
Does "ifup ippp0" work?
ifup ippp0 starts the interface, but hangs the command line for the same reason
as above. (I took the & out of the ifup-ippp script to test it). Put the & back
in and it works fine again.
Those scripts are part of initscripts.
