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" http://live.gnome.org/NetworkManager/SystemSettings -- Konstantin Olchanski Data Acquisition Systems: The Bytes Must Flow!
