Description giulioo 1999-08-30 08:29:56 UTC

Stock rh60.


== Problem:
Pppd logs to syslog AND to the console instead of just to
syslog.


== Situation:
I connect a rh6 server and a diskless pc (boot linux from a
floppy) via serial line/ppp.


== PPP setup on the rh60 server:
1) iinittab:
S0:234:respawn:/usr/sbin/pppd ttyS0
2) /etc/ppp/options:
lock
3) /etc/ppp/options.ttyS0:
:10.0.0.101
-detach
silent
persist
netmask 255.0.0.0
asyncmap 0
proxyarp
crtscts
ipcp-accept-remote
ipcp-accept-local
115200


== /etc/sysconfig/init
I have loglevel=7 (but this shouldn't have anything to do
with the problem)


== What pppd logs to the console:
pppd logs to the /dev/tty1 the following stuff (WHEN the
serial cable is connected to ttyS0):

1) At boot it logs
--
Using interface ppp0
Connect: ppp0 <--> /dev/ttyS0
--
cluttering the login prompt

2) when the diskless pc connects to it
--
found interface eth0 for proxy arp
local  IP address x.x.x.x
remote IP address x.x.x.x
--

3) when the diskless pc does ppp-off
--
LCP terminated by peer
Connection terminated.
Connect time 4.4 minutes.
Sent 320 bytes, received 363 bytes.
Hangup (SIGHUP)
Using interface ppp0
Connect: ppp0 <--> /dev/ttyS0
--

The PPP connection works perfectly, but the console is too
much cluttered with merely informational pppd messages.


== Why I think this is a bug:
I looked at the pppd source and it logs those messages
under daemon.notice and daemon.info, so that they should go
to /var/log/messages only (if I understand the stock
syslog.conf), not to the console too.

I used pppd in the same manner (with the same serial cable)
on a caldera13 (2.0.33/ppp2.2.x) box and it didn't log
anything to the console.

Just to try, I set up a syslog.conf with
*.*         /var/log/messages  (tab not spaces)
killall -1 syslogd
but the problem persists.

Is this a normal behavior or a bug?

Thanks.

I think this is considered a feature when pppd is run with a
controlling terminal, though I may be mistaken.  Have you
tried running pppd with standard in, out, and err redirected
from/to /dev/null?
pppd [arguments] </dev/null >/dev/null 2>/dev/null

Comment 2 Anonymous 1999-11-09 10:01:59 UTC

You're right, with
S0:234:respawn:/usr/sbin/pppd ttyS0 1>/dev/null
the console is not cluttered anymore.

However, I think this behavior is not so intuitive; usually stuff run
from inittab doesn't log to console, but for critical problems. And
the old pppd did this way.

Thanks.

Comment 3 Michael K. Johnson 1999-11-22 16:55:59 UTC

If you would like, you may discuss your preferences for pppd's behaviour
to pppd's author; we can't be very effective middlemen on this.
