Dan, you have amazing energy. Please ignore whatever I said earlier as I reimaged the box to Fedora 15. :-) I have wasted the whole day on NetworkManager. config: 2.6.38.6-26.rc1.fc15.x86_64 NetworkManager-0.9.1.90-3.git20110927.fc15.x86_64
I have the following problems currently: 1) When I boot, by default eth0 not coming up. I need to type at console "nmcli con up ..." How do I fix it? 2) This is a headless machine. If I start vncviewer (remote connection) under a non-root account, why does it not let me define a PPTP VPN? The place to put in gateway etc is greyed out. I had to do it as root. But, if I am logged on to the machine locally without root, it lets me do it via X. Can you please explain the security going on here? 3) [Ubuntu 10.10] I read the source code for NetworkManager. It looks like I cannot setup a PPTP VPN via NetworkManager if I setup my network manually via wvdial. Is that right? The reason I setup manually is that UML290 does not work properly in NetworkManager and sometimes it works in wvdial. :-) This device and the service is a crappy one even in good coverage. So is the Windows software that the telecom provider provides. Yuckiest software I deal with. Any ideas on how to reverse engineer the software? It does not use the typical modem devices.

When I do Can you paste in your /etc/sysconfig/network-scripts/ifcfg-eth0? Also check and make sure that NM_CONTROLLED=yes in that file.
