Re: [gentoo-user] Re: qemu not working on a P3M
if I try and use qemu-386 it has limited cmd line options according to -h, and barfs on any of the normal options such as -cdrom - hence my feeling its missing a wrapper. thanks, might have to do git to see if its different.

[gentoo-user] multiple bluetooth devices
I am using a single BT usb dongle to communicate over rfcomm with two BT Arduino based devices. Individually they work fine but if one is connected (to rfcomm1), but any attempt to use the other (rfcomm0) fails and knocks the first into limbo requiring recovery. The BT spec implies up to 8 clients can communicate over a single BT device. Ive also tried using different channels for each but the clients look like they are channel 1 only. Can anyone see a way around this or will I need to do some kind of polling to make sure the other device isn't using it before attempting comms? The server is using bluez 4 with the standard gentoo files with the two devices parameters set in /etc/bluetooth/rfcomm.conf. BillK

Re: [gentoo-user] Re: Recommended VPN Tunnel client?
Congestion isn't the only reason to use TCP and a VPN. 3G smartphone network (Optus in Oz) has a large number of duplicate and dropped packets - openvpn performance over TCP is much better. Similar case with a cheap French network while on holiday there. This was an extreme case though with non VPN traffic very poor as well. Otherwise use openvpn with fqdn's and not IP numbers then use ospf across them with suitable route metrics to either share or prefer a route. Works well with dynamic IP's from my ISP so should be ok in your scenario. You could also use openvpns route push if you dont need complex dynamic routing - this works better than ospf on bad links anyway.
