[Solved] net.eth0 vs. networkmanager

[enrico3791]

Since I installed Networkmanager and made it start by default at boot, I noticed that I receive and error message from net.eth0:

'dhcpcd already running on pid ...'

and eth0 stop working leaving me without a network connection.

I tried several interactive boot skipping one of these two service at once. Network works perfectly when just one is activated.

Is there a conflit among them? Can I delete net.eth0 from boot services?

Regards
Enrico

Do you have /etc/conf.d/rc or /etc/conf.d/rc.conf

I have only /etc/conf.d/rc.

# /etc/conf.d/rc: Global config file for the Gentoo RC System

# This is the number of tty's used in most of the rc-scripts (like
# consolefont, numlock, etc ...)

RC_TTY_NUMBER=12

# Set to "yes" if you want the rc system to try and start services
# in parallel for a slight speed improvement. NOTE: When RC_PARALLEL_STARTUP
# is enabled, init script output is replaced with simple "service foo
# starting/stopping" messages so that output is not mixed up.
# You can stop this from happening on the command line by passing --verbose
# to the init script or by setting RC_VERBOSE="yes" below.

RC_PARALLEL_STARTUP="no"

# Set RC_INTERACTIVE to "yes" and you'll be able to press the I key during
# boot so you can choose to start specific services. Set to "no" to disable
# this feature.

RC_INTERACTIVE="yes"

# Do we allow services to be hotplugged? If not, set to RC_HOTPLUG="no"
# NOTE: This does not affect anything hotplug/udev related, just the
# starting/stopping of the init.d service triggered by hotplug.

RC_HOTPLUG="yes"

# Dynamic /dev managers can trigger coldplug events which cause services to
# start before we are ready for them. If this happens, we can defer these
# services to start in the boot runlevel. Set RC_COLDPLUG="no" if you don't
# want this.
# NOTE: This also affects module coldplugging in udev-096 and higher
# If you want module coldplugging but not coldplugging of services then you
# can set RC_COLDPLUG="yes" and RC_PLUG_SERVICES="!*"

RC_COLDPLUG="yes"

# Some people want a finer grain over hotplug/coldplug. RC_PLUG_SERVICES is a
# list of services that are matched in order, either allowing or not. By
# default we allow services through as RC_COLDPLUG/RC_HOTPLUG has to be yes
# anyway.
# Example - RC_PLUG_SERVICES="net.wlan !net.*"
# This allows net.wlan and any service not matching net.* to be plugged.

RC_PLUG_SERVICES=""

# RC_NET_STRICT_CHECKING allows some flexibility with the 'net' service.
# The following values are allowed:
# none - The 'net' service is always considered up.
# no - This basically means that at least one net.* service besides net.lo
# must be up. This can be used by notebook users that have a wifi and
# a static nic, and only wants one up at any given time to have the
# 'net' service seen as up.
# lo - This is the same as the 'no' option, but net.lo is also counted.
# This should be useful to people that do not care about any specific
# interface being up at boot.
# yes - For this ALL network interfaces MUST be up for the 'net' service to
# be considered up.

RC_NET_STRICT_CHECKING="no"

# RC_DOWN_INTERFACE allows you to specify if RC will bring the interface
# completely down when it stops. The default is yes, but there are some
# instances where you may not want this to happen such as using Wake On LAN.

RC_DOWN_INTERFACE="yes"

# RC_VOLUME_ORDER allows you to specify, or even remove the volume setup
# for various volume managers (MD, EVMS2, LVM, DM, etc). Note that they are
# stopped in reverse order.

RC_VOLUME_ORDER="raid evms lvm dm"

# RC_VERBOSE will make init scripts more verbose. Only networking scripts
# really use this at this time, and this is useful for trouble shooting
# any issues you may have.
# This is also used to re-enable init script output for init scripts
# started or stopped from the command line.

RC_VERBOSE="no"

# RC_BOOTLOG will generate a log of the boot messages shown on the console.
# Useful for headless machines or debugging. You need to emerge the
# app-admin/showconsole package for this to work. Note that this probably
# won't work correctly with boot splash.

RC_BOOTLOG="no"

# Set to "yes" if you want to benchmark system boot with bootchart.
# You'll need to emerge the app-benchmarks/bootchart package for this to work.

RC_BOOTCHART="no"

# RC_USE_FSTAB allows you to override the default mount options for the
# standard /proc, /sys, /dev, and /dev/pts mount points. Note that this
# is the new way for selecting ramfs/tmpfs/etc... for udev mounting.

RC_USE_FSTAB="no"

# RC_USE_CONFIG_PROFILE allows you to have different /etc/conf.d files
# based on your runlevel - if a conf.d file for your profile does not exist
# then we try and use the default one.
# To enable runlevel selection at boot, append "softlevel=foobar" to your
# kernel line to change to the foobar runlevel. Here we would search for
# /etc/conf.d/<service>.foobar config files before trying to use the default
# /etc/conf.d/<service>.
# Note that it is only active if 'softlevel' was specified via the kernel line,
# and it is intended to use for different grub/lilo entries to specify config
# changes for say laptops between home and work, where you would have setup
# 'work' and 'home' runlevels, with /etc/conf.d/*.<runlevel> as needed.

RC_USE_CONFIG_PROFILE="yes"

# RC_FORCE_AUTO tries its best to prevent user interaction during the boot and
# shutdown process. For example, fsck will automatically be run or volumes
# remounted to create proper directory trees. This feature can be dangerous
# and is meant ONLY for headless machines where getting a physical console
# hooked up is a huge pita.

RC_FORCE_AUTO="no"

# Use this variable to control the /dev management behavior.
# auto - let the scripts figure out what's best at boot
# devfs - use devfs (requires sys-fs/devfsd)
# udev - use udev (requires sys-fs/udev)
# static - let the user manage /dev (YOU need to create ALL device nodes)

RC_DEVICES="auto"

# UDEV OPTION:
# Set to "yes" if you want to save /dev to a tarball on shutdown
# and restore it on startup. This is useful if you have a lot of
# custom device nodes that udev does not handle/know about.

RC_DEVICE_TARBALL="no"

# RC_DMESG_LEVEL sets the level at which logging of messages is done to the
# console. See dmesg( for more info.

RC_DMESG_LEVEL="1"





#
# Controlling start-stop-daemon behavior

# Set to "yes" if start-stop-daemon should always retry killing the
# service with sig KILL if it fails the first time.

RC_RETRY_KILL="yes"


# Set the amount of seconds start-stop-daemon should wait between
# retries.

RC_RETRY_TIMEOUT=1


# Set the amount of times start-stop-daemon should try to kill
# a service before giving up.

RC_RETRY_COUNT=5


# Set to "yes" if start-stop-daemon should fail if the service
# is marked as started, but not actually running on stop.

RC_FAIL_ON_ZOMBIE="no"


# Set to "yes" if start-stop-daemon should attempt to kill
# any children left in the system.
# Be careful with this as it really does what it was on the tin.
# fex, if you're in an ssh process and you restart a service on which ssh
# depends then your terminal will be killed also.

RC_KILL_CHILDREN="no"


# Set the amount of seconds start-stop-daemon waits after starting
# the daemon to check it is still running. If it's not then we
# try and stop any children if possible.
RC_WAIT_ON_START="0.1"

So if you want to stop eth0 and wlan0 from being started and have another program handle it.
RC_PLUG_SERVICES="!net.eth0 !net.wlan0".
