Why ' RTNETLINK answers: File exists '
Environment: centos 5.4
State one.
After installing the centos network related configuration changes, use the / etc / init.d / network restart
There will be "RTNETLINK answers: File exists" message.
Situation Two.
/ etc / resolv.conf changes well after each reboot the modified data will be lost.
The first question is probably because both have launched two network management services, that network and NetworkManager.
If the / etc / resolv.conf the first line is also found in NetworkManager edit related words can be sure this is the program go wrong has.
Solution:
NetworkManager starts the network to remain one with like.
NetworkManager is on Red Hat in 2004, initiated by the development of the network connection management software, designed to allow users to easily manage network connections and switch between multiple networks (especially wireless network).
Fedora Core 3 starting from the collection of NetworkManager, Ubuntu from 6.06 LTS (Dapper) began included.
If you are using the graphical interface:
# chkconfig - level 35 NetworkManager on
# chkconfig - level 0123456 network off
/ / Set the network boot does not start, 35 in the startup mode for the start NetworkManager
# / sbin / service NetworkManager stop
# / sbin / service network stop
/ / First two services currently in operation are stopped
# / sbin / service NetworkManager start
/ / Start the network management interface
If you are using text mode:
# chkconfig - level 35 network on
# chkconfig - level 0123456 NetworkManager off
/ / Set the boot mode, NetworkManager does not in any start, just start the network
# / sbin / service NetworkManager stop
# / sbin / service network stop
/ / Two stop service
# / sbin / service network start
/ / Start the network
Note: The above two methods use the same choice.
Is set up if you do not worry, you can try to reboot and use the / etc / init.d / network restart to see if an error message will appear.
