Re: NetworkManager from command line

[Mohan Sfo <mohansfo yahoo com>]

All,

Two issues in this mail.

1) Trouble starting VPN via "nmcli con up uuid"

2) "nmcli con" not showing a connection setup via nm-applet under vncserver.  I typed nmcli both as root and regular user. Why?  Presumably some permission is failing. How do I fix it?

Reg 1:

Dan, Thanks.  I did what you said.  It is not working, with NetworkManager thinking there is no network connectivity.  I definitely have network connectivity as I am able to ping Google.  But, NetworkManager is not understanding it.  This network connectivity is coming up at startup on eth0 due to legacy Redhat scripts (/etc/sysconfig/network-scripts/ifcfg-eth0). When I do

nmcli con up uuid <uuid>

I get this error: Error: No suitable device found: no active connection or device.

How do I get NetworkManager to realize there is a connection or override it's connection availability checking?  NetworkManager-0.8.4-1.fc14.i686

Can you help?  Thanks.

NetworkManager.conf reads:

[main]
plugins=ifcfg-rh,keyfile

At the moment, VPN connections can be configured manually by editing
'keyfile' connection files in /etc/NetworkManager/system-connections.  A
sample PPTP keyfile is as follows:

[connection]
id=Sample PPTP
uuid=2b88c363-f97e-4e76-9ee6-8b9bb136e75b
type=vpn
autoconnect=false

[vpn]
service-type=org.freedesktop.NetworkManager.pptp
gateway=1.1.1.1
user=dcbw
password=myspace

[ipv4]
method=auto

You can change various other options.  One way to do that is to run
nm-connection-editor on a machine with a GUI and set up the connection,
then copy the connection file when you've got it set up right.
