I have one box that acts as the gateway for my house network. We only have
a dial up line. I have been using pppd with 2.3.x and 2.4.x kernels for
some time with this setup. I upgraded to 7.1 a day or so ago. Now, the
demand and persistent connections make pppd or ppp-watch spawn multiple
pppd's. For example: Connection is terminated. I should only have one
pppd running with an entry of ppp0 in ifconfig for it. Now, with RedHat
7.1 I get two pppd's and ppp0,ppp1 in ifconfig. This was an upgrade
install and not a clean install. I believe though that all 7.1 things were
installed that had previous parts. No dependency problems.
Steps to Reproduce:
1. Create a pppd connection
2. Make it demand in options and make it persistant
3. Get it to connect
4. Drop connection
5. ps xa, ifconfig
Actual Results: I get too many ppp interfaces and pppd's running.
Expected Results: One pppd running. One interface.
I have found additional things. I still do not know if ppp-watch or pppd is at
fault. The above directions do not cause the problem. It seems pppd is
unkillable, however, ppp-watch seems to see the signal to die and spawns a new
pppd. Hence the multiple pppd's.
I had reasons for having if-down.local in /etc/ppp kill the pppd (I cannot
remember this late at night what they were, it seems it had to do with some
other program working right). It is a bug for pppd to ignore the QUIT (I
believe that is the default for kill) signal. It is also a bug for pppd to see
that signal and assume pppd is dead and restart it without verifying that pppd
Two bugs: pppd doesn't respond to the signal mentioned above, and ppp-watch
restarts pppd when it shouldn't.
I suspect this is a duplicate of bug #39231.
There's a patch there, please tell if it fixes your problem.
I had a similar issue with ppp-watch. It did not redial when the connection was broken, like it did in RH 6.2. Until a new release of initscripts is released, I
simply copied the ppp-watch program from my system backup tape, and replaced the rh 7.1 version. Works like advertised, now.
Please verify this with a newer version of Red Hat Enterprise Linux or Fedora
Core and reopen it against the new version if it still occurs.
Closing as "not a bug" for now.
