I'll have to admit that I am rather old school when it comes to administering
my machines. I usually like to take a more active approach than
letting a daemon make decisions for me. I used to hack on
/etc/network/interfaces and /etc/resolv.conf to get what I wanted
done, and in some ways I am missing that level of control...
I have an HP laptop with a wired and a wireless interface. My
network usage falls into three models:
- wireless, no VPN, roaming
- wired, no wireless (in the office) DHCP on wired
- wireless, VPN, dhcp, no wired (tun0 interface created)
I run into several issues with NetworkManager:
- if I have been working at home, (wireless, WEP, VPN) and transition to
the office, I have to manually enable the wired interface.
- if I have been working in the office (wired, no VPN) and come home,
I generally have to fiddle with enabling/disabling wireless and wired
interfaces until I get a DHCP address from the wireless router. I
sometimes have to kill dhclient and clear out /var/lib/dhcp3 in order
for NetworkManager to realize it has to go get a new ip. The
interface will be 'up' but no. No errors from dhcp on router.
- if am working with the VPN (tun0) wireless and the little checkbox
is ON next to the wired interface, I am *assured* that my connection
will drop periodically. Usually 5-10 minutes. If I manage to get
NetworkManager to leave off the little checkbox, then it will stay up
I've tried setting up profiles for this and this sometimes works. I
still have to 'bounce' between profiles at time to get it to trigger
dhclient properly. I typically NEVER suspend and resume - these are
What is strange is if I revert to manual management of
/etc/network/interfaces, I get a high level of stability - switching
between wired and wireless is swift and certain. I can control
whether dhcp runs or not on the wired interface.
All this leads me to think that I am not using this in the right way.
I think my needs are:
- if I am wired, I don't care about the wireless interface
- if I am wireless, I don't want the wired interface to even be probed
Am I missing something critical in my use model? Any pointers are
