comment How to detect whether there is a CD-ROM in the drive?
blkid detects partitions, If i put a audio CD, it is not detected. Didn't find a easier solution than create a program using ioctl as described in stackoverflow.com/questions/15652520/…

comment What kernel modules are required for wi-fi to work?
Why do you still use those old kernel versions and those prehistoric tools like iwconfig and iwlist ?

comment What happens if my neighbour sets his wifi SSID the same as mine?
@piernov: No, there are way too many large-scale ESS network out there. If your connection manager had to display all BSSes, you would see many AP with the same SSID in a large WLAN deployment. And your device will typically transparently roam between APs in the ESS.

comment WLAN probe requests' content
I suspect Android does it, since i've seen ap_scan=2 in a android-generated wpa_supplicant.conf file. Need to be confirmed though.

That's a different question.

If you use only one IP address, this is almost trivial to do.

Using a different address when sending would break all upper-layer protocols, except maybe SCTP.

comment What is a u-Boot dtb file and how do I use it (BeagleBoard xM)?
It's the new(er) way to pass hardware information about the board to the Linux kernel. There were no previous way to pass hardware information to the kernel. Instead, the kernel would have to statically include all the information and so would have a board-specific C file to list all those mappings. This was a maintenance nightmare from the kernel point of view.

comment The network setting for /etc/network/interfaces for static IP of a supernet address
And nobody told you that classful addressing has been deprecated and dead for 20 years now ? All the Internet uses Classless interdomain routing now (CIDR for short, see RFC 4632), so there is no concept of "classes" or "supernetting" anymore. You may even specify a prefix length in netmask (like netmask 20) instead of a netmask.

network is totally ignored by ifupdown, the system can figure it by itself anyway. Your broadcast is useless here: the system will pick the same in your case. Your gateway is not part of your subnet, so ifupdown will fail at that point.

@xpt: ip addr gives you the modern CIDR prefix length just next to the IP address. It also accept old-style netmask on input (i.e. 192.168.31.254/255.255.240.0)

Stop using ifconfig, use ip addr instead. This is what ifupdown (the software that parses /etc/network/interfaces) uses under the hood anyway, so you will definitely want to get used to it.

comment Is Wifi hotspot really different form repeater?
@whiteSkar: It will not dramatically decrease. It may stay the same or decrease a bit. Now good luck finding a cheap dual-radio repeater.

comment Configuring network after initial install of gentoo?
@StevieG: iwconfig and wireless extensions are totally obsolete by today's standard, as they do not even support 802.11n properly, let alone 802.11ac. Use iw instead. The kernel option to enable wext hackward compatibility (it is such an horror that it lies most of the time) is CONFIG_CFG80211_WEXT and is disabled by default. Keep it disabled and forget about iwconfig. All other tools moved to the newer nl80211 kernel API.

comment Is there a serial terminal program that allows filtering the messages?
You will need to configure the serial parameters first, since grep won't do it.
