modem-manager writes to log every 2 seconds

Binary package hint: modemmanager

I've got an UMTS modem. My log:

$ tail /var/log/daemon.log

This causes permanent disk access that I want to prevent it from. How?

I created a little workaround for this problem.

To apply:

sudo -s
cat <<_EOF_>/etc/rsyslog.d/49-modemmanager-workaround.conf
# Workaround for bug from modemmanager spamming the logs
# https://bugs.launchpad.net/ubuntu/+source/modemmanager/+bug/662791

:msg, contains, "Duration: " ~

& ~

:msg, contains, "Access Technology: " ~

& ~
_EOF_
service rsyslog restart

This will prevent modemmanager writing these two types of messages to any log. Works for me at least.

first download the modem-manager 0.4 source files, then in the plugins folder
 open "mm-modem-huawei-gsm.c" and goto line 519

change...

[B][COLOR="MediumTurquoise"] g_debug ("Access Technology: %d", act);
[/COLOR][/B]

to...

[B][COLOR="DarkOrchid"] if (mm_options_debug ()){
        g_debug ("Access Technology: %d", act);}[/COLOR][/B]

then on line 533 change...

[B][COLOR="MediumTurquoise"] g_debug ("Duration: %d Up: %d Kbps Down: %d Kbps Total: %d Total: %d\n",
                 n1, n2 * 8 / 1000, n3 * 8 / 1000, n4 / 1024, n5 / 1024);[/COLOR][/B]

to...

[B][COLOR="DarkOrchid"] if (mm_options_debug()) {
            g_debug ("Duration: %d Up: %d Kbps Down: %d Kbps Total: %d Total: %d\n",
                     n1, n2 * 8 / 1000, n3 * 8 / 1000, n4 / 1024, n5 / 1024);}[/COLOR][/B]

then using Terminal "[B]cd[/B]" to the modem-manager directory (source)
ie: "//home/username/Downloads/modem-manager"

and run

[B]./configure
make
make instal[/B]l

you may need to get some dev dependences using apt-get install or synaptic or whatever u use

this way the problem will be fixed not worked around ;)
and the info will still log if in debug mode

ps the" mm_options_debug()" function is in the "mm-options.c" file in the "src" folder if anyone was looking...

OH OK NO HTML

first download the modem-manager 0.4 source files, then in the plugins folder
open "mm-modem-huawei-gsm.c" and goto line 519

change...

g_debug ("Access Technology: %d", act);

to...

if (mm_options_debug ()){
g_debug ("Access Technology: %d", act);}

then on line 533 change...

g_debug ("Duration: %d Up: %d Kbps Down: %d Kbps Total: %d Total: %d\n",
n1, n2 * 8 / 1000, n3 * 8 / 1000, n4 / 1024, n5 / 1024);

to...

if (mm_options_debug()) {
g_debug ("Duration: %d Up: %d Kbps Down: %d Kbps Total: %d Total: %d\n",
n1, n2 * 8 / 1000, n3 * 8 / 1000, n4 / 1024, n5 / 1024);}

then using Terminal "cd" to the modem-manager directory (source)

[sonnettie (sonnettie)]

just thought you will need to look in whatever "*.c" file in the plugins folder that corisponds to your modem vendor mine is huawei but dont know if yours is

[sonnettie (sonnettie)]

oh also add the following to line 30...

#include "mm-options.h"

I chose ThomasNovin's solution because I didn't want to give up my repo.

Thanks!

@sonnettie:

Why not supply your patch to fix it in the Ubuntu packages?

[Mathieu Trudel-Lapierre (cyphermox)]

I believe we should instead get rid of that logging altogether (or make it optional through some switch or whatnot) and provide this information through the info dialog in nm-applet... Patches are welcome, or I'll get to it eventually :)

Since it's really an upstream issue though, please bring this up on the NetworkManager mailing list (see http://live.gnome.org/NetworkManager) which also hosts the ModemManager stuff; that way there can be some discussion and a decision made on the best way to fix the issue.

Thanks!
