Description of problem:
Sometimes (I haven't figured out the causes) when I do /sbin/ifup pppX it
never returns altough the link is up and usable. I've tried with more than
one ISP and it still happens.
When the problem happens, running top shows two ppp-watch processes along
Steps to Reproduce:
1. /sbin/ifup ppp0
Actual Results: Sometimes I never get the command prompt back
Expected Results: It should have returned to the command prompt after the
link was up.
I'm running ipcheck from /etc/ppp/ip-up.local to update my dyndns.org
account but it updates and returns normally (specifically when the problem
I'm using ppp over a 56K modem line to my ISP.
ifup-ppp is syncrhonous. It should only return when the link goes down, or,
if you call it when it's already up, after initiating a redial.
I've always used /sbin/ifup to bring up my ppp link and /sbin/ifdown to bring
it down and before redhat 7.1 it returned back to the command line 100% of the
times, now it only returns 90%.
