Re: [gentoo-user] [OT] Linux Live CD to perform hardware audit?
But do any of you guys/gals know of a Live CD distro that can perform hardware audit? i.e., detect installed processor model, RAM parameters layout, etc. Some days ago I was using the parted magic live cd [1]. It had a tool that listed all hardware in a nice fashion. I don't recall it's name - but looking at the list of programs that come with parted magic [2] I guess it was hardinfo.

Re: [gentoo-user] Google - can not open any link
You are right on; I disable Java in firefox and now can open links in google search. As I said, I have disabled cookies and javascript for goolge.de (using cookiemonster an noscript). But as I sometimes use google maps, I allow javascript on google.com and then use google.com for maps - with cookies disalbed. And here I have the same issue as you have, I cannot open the links, but the strange thing is: it's not all the time, sometimes it works, sometimes it does not. Who knows what google guys were doing. Maybe they left a screw driver in there or something :)

So I guess I'll just shutdown the box, boot using the Live CD, record all important info, and reboot into the hypervisor. Rgds, Pretty much any livecd that'll boot can do the job... lspci -vv, /proc/cpuinfo, /proc/meminfo, and fdisk -l (which'll catch any drives the running kernel sees at least) are pretty standard, and it wouldn't take much to include a script that calls those, dumps the output somewhere, then reboots. For more extensive info, dmidecode and lshw tend to give more detail, but are a little less 'standard'. Notably, dmidecode gives things like per-slot ram information. Software does indeed make this process so much easier. We use dmidecode for this too. All the machines in the data center run ocsng (http://www.ocsinventory-ng.org) to automate the entire process, but that's way beyond what the OP needs -- Alan McKinnnon alan.mckin...@gmail.com

(DDG doesn't handle long literals very well; queries for things like long model numbers don't usually work out.)

Best regards, mcc Do you mean to play music using a Linux soft synth, or possibly to record the midi messages and be able to replay the music using an external synth? Both are completely possible, and in fact easy with the right MIDI-to-USB converter. I use a MIDIMAN MIDISport 2x2 which works great for me although I haven't used it in a while. I'm sure there are lots of good USB interfaces that cost less that work fine also. http://www.amazon.com/M-Audio-Midiman-Midisport-MIDI-Interface/dp/B6I5HC Best _up_to_date_ info for this would be I think on the Alsa user list but feel free to write me off line if you you want a little quick info.

Hi,
I have installed wpa_supplicant and changed the country entry
in /etc/wpa_supplicant/wpa_supplicant.conf and also added a few lines at
the end of the file:
network={
ssid=my_essid
psk=my_ascii_password
priority=5
}
Then I created a symbolic link to /etc/init.d/net.lo called
/etc/init.d/net.wlan0 and that was it I think ... also set
rc_hotplug to net.wlan0 !net.* in /etc/rc.conf.
That should be all to get wireless networking going if the kernel module
for your network card is loaded and you have the firmware for it in
/lib/firmware.
Using kernel 3.1.5 at the moment and the carl9170 driver.

[gentoo-user] Recommended VPN Tunnel client?
Scenario: I have a server in the cloud that needs to connect to an internal server in the office. There are 2 incoming connections into my office, ISP A and ISP B. The primary connection is A, but if A goes down, we can use B. The app running on the cloud server has no automatic failover ability (i.e., if A goes down, someone must change the app's conf to point to B). My thought: If I can make a tunnel from the server to the FortiGate firewall currently guarding the HQ, the cloud app can simply be configured to connect to the internal IP address of the internal server. No need to manually change the app's conf. The need: a VPN client that: + can selectively send packets fulfilling a criteria (in this case, dest= IP address of internal server)* + has automatic failover and failback ability *solutions involving iptables and iproute2 are also acceptable Can anyone point me to the right direction re: what package and the relevant howto?
