This is fine if I am the only manager of the computer.
When there is an emergency when I am on vacation, the secondary manager
will read the RHEL/SL documentation, which will direct them to run
system-config-network or open the NetworkManager applet, and where does that take them?
Maybe they will remember to "vi ifcfg-eth0", maybe not.
It is best if one could use the tools recommended by, supplied by
and document by the vendor - I want to run "RHEL/SL Linux",
not "Konstantin's Linux".
P.S. Okey, so what do RHEL recommand and document?
- start at http://docs.redhat.com, follow links to RHEL6 "Deployment guide":
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide
- read the section about "network time setup"
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/sect-Date_and_Time_Configuration-Command_Line_Configuration-Network_Time_Protocol.html
- here they tell us to add
NETWORKWAIT=1
to /etc/sysconfig/network (somebody wrote about this already)
- read the section about "configuring network connections"
http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/6/html/Deployment_Guide/sec-Configuring_New_and_Editing_Existing_Connections.html
- here they tell us to run the X11 application "nm-connection-editor"
- on following pages they tell us about:
- checkbox "available to all users" is new-speak for "do not shutdown this connection when user logs out"
- checkbox "connect automatically" is new-speak for "start interface at boot time".
Obviously, I did not follow this documentation when I ran into my trouble
with NIS and autofs, and other trouble.
P.P.S. What about documentation for the NetworkManager?
Google NetworkManager documentation. After following many false
trails, you will eventually find the NetworkManager web pages
on the GNOME site. From there you will eventually find
their Wiki, and there you will find the page that describes
how NetworkManager stores it's configuration. You will discover
that it uses a system-dependant plugin system and you will need
to look at a file on your computer to find out what plugin
is actually used. SL seems to use the "ifcfg-rh" plugin, so we go to
that section, and behold, here are documented all the NM-special
ifcfg-eth0 settings.
Here is the URL, scroll down to the section "ifcfg-rh"
