You can test this firmware and the hardware by typing; ok select /wlan:force ok d# 11 " xoap" start-ap A network xoap should then be visible on other laptops. The test network has no associate, authenticate, or DHCP service, so it is not particularly useful alone. The purpose of this test network is to make sure your hardware and firmware is working. You can add associate and authenticate support by rebooting and typing: ok select /wlan:force ok do-ap This kind of access point is useful for antenna and packet testing. See http://wiki.laptop.org/go/Antenna_testing You can also test the later firmware by setting an environment variable before the select command; ok setenv wlan-fw u:\p3.bin Once you have verified working hardware, firmware, and both antenna, you're all set to test in the operating system. ;-) (The second antenna becomes way more critical when using an XO as access point or NANDblaster transmitter.

Look at the interrupt count for the device in /proc/interrupts; if there are lots of interrupts, I'd say the module has communicated with the wireless card.

It may be that the kernel support for this isn't as tested in 4.1 as it was in previous versions. Thanks for investigating. > 3.

The design of the kernel modules supports both the USB8388 wireless card on the XO-1, and the SD8686 wireless card on the XO-1.5. Unless you plan to use the (deprecated, unavailable) external USB83833 active antenna devices, you can omit the USB support. I doubt it will have any effect. -- James Cameron http://quozl.linux.org.au/ ___ Server-devel mailing list Server-devel@lists.laptop.org http://lists.laptop.org/listinfo/server-devel
[Server-devel] XO1.5 as Access Point using thinfirm
Thanks to James Cameron's work on FC22 kernel, I have an image of XSCE running in an SD card on an XO1.5. The regular libertas driver works as a client. There is documentation for using a special driver, and special firmware at http://wiki.laptop.org/go/Libertas_Thinfirmware_HOWTO: http://wiki.laptop.org/go/Thinfirm_1.5 http://wiki.laptop.org/go/Test_Report Which I have attempted to follow. I have added config items(below) and created a new kernel. Questions; 1. The libertas_tf module loads via modprobe (after rmmod libertas cfg80211) Does this mean that it has found the firmware? 2. After blacklisting libertas, and a reboot, there is a new device sit0, which may indicate that the proper network driver is not being found/loaded.(dmesg is quiet about libertastf) 3. Are there incompatabilities between libertas_sdio and libertas_usb -- should it be one or the other?

Re: [Server-devel] Trying to access a school server from the outside world
I would need access 'lascahobas' server, because the new server is not available yet. Could you provide me the client information needed? Sorry to bother, I didn't used openvpn before.

Re: [Server-devel] Trying to access a school server from the outside world
I thought I had already set you up for using the Amazon passthrough. But here are the steps: 1. There is a user at the https://50.17.210.12:943/admin/ port with username:gonzalo and a password I will send separately. 2. Sign on there and change your password. You can use this sign on at any time to see if the "sora server" client connection is available at the passthrough. 3. Then you will need to create a new user without administrative privileges that will become the server's client connection to the vpn. The generation of the keys for the "sora server" is triggered by accessing https://50.17.210.12:943/ (without admin), and logging on with the credentials you created when you set up the "sora server" user. 4. When you make this https:// access, the amazon openvpn application will offer to let you download the openvpn client application. I have usually "yum installed" openvpn already. Hit refresh, and you will be given a choice to download an unattended access key file. 5. Download the "cient.ovpn" file and change it so something similar to the username you created. Place it in the /etc/openvpn/ directory of "sora server" Sorry I missed your request when it came 3 days ago.
