@slm I started editing this one unix.stackexchange.com/a/104816/33055 in the first posts queue until I hit the "Can any please help me"... and I cancelled and flagged as not an answer. (especially because I find adding <kbd></kbd> tags cumbersome. Is there a keyboard shortcut for that)?
@Anthon - I've not found one either, I do them by hand. I edited that Q but flagged it as not an answer too.
I use the auto proforma chrome plugin for the auto comments. I'd look around stackapps, there are lots of addons to the browser to make things more automated for the regulars on the SE sites.
Inspired by the question, "Markdown syntax for <kbd>foo</kbd>", this script adds both a button and a keyboard shortcut to each post's <textarea> (when editing posts).
Press the button or press AltK on the keyboard and <kbd></kbd> will be inserted at the cursor.
If text is selected, it will...
Hi, I am trying to block new TCP packets which have flags set along with SYN. Like SYN & FIN set at same time. Will the below rule for iptables suffice-
iptables -A INPUT -m state --state NEW -p tcp --tcp-flags ! ALL SYN -j DROP
@derobert +1 on that answer, the history is really interesting. but since it's userspace, isn't udev just doing mknod behind the scenes? so wouldn't you still need to allocate major/minor device numbers? (should I take that to main?)
@strugee The difference is that the kernel can (and does) dynamically assign the numbers, and tell those to udev. udev doesn't actually know the numbers (with maybe a few exceptions) ; it gets them from /sys. (Going to bed, but how that works would make a good question on the site.)
According man hdparm , -B254 do not permit spindown. -B(1--127) permits spindown.
But -B127 -S240 will makes Load_Cycle_Count increase too fast about 4/minute.
How to set up hdparm parameter? I use laptop computer.
Thanks

Values 1-127 permit spin-down, 128-254 do not and 255 disables
advanced power management altogether (if the drive supports it).
Values 1 to 240 are in 5 second steps, values 241 to 251 are steps of
30 minutes, see the table below.

My friend has installed Fedora 19 on his Samsung laptop Series 5 Ultra (np530u3c-ad2br). It runs live linux instaces fine. Upon boot it shows this screen, and upon pressing enter, the same screen is shown again.
Secure UEFI boot is disabled.
Thanks to @Affix's answer which gave me the right direction to head, I've figured out the solution to the problem.
The problem is definitely caused by UDEV as you've guessed. The issue is this line that is in most UDEV files related to the cdrom drive.
