How to open a port early in boot process to unlock LUKS via SSH
I have a fully encrypted server running Debian 7 and have set up dropbear and busybox to unlock the LUKS container via SSH (as described in this tutorial and in this U&L answer).
Which user group can use the ‘tap’ net device?
I use the ‘tap’ net device with KVM to get my vm connect to the Internet. But I have to be root, or use ‘sudo’, which is inconvenient. I think I can put my user account into some group so I can access the net device without root privilege. I tried the netdev group, but does not work. My account is already in the kvm group.

How do I resolve samba share to IP address or host name
I have a list of hosts in the network providing shares via SAMBA. How can I determine either IP address or the host name of one particular host, e.g. the one with the name “SASAK02”.
The difference between ip link down and physical link absence
In Linux, is there any difference between after-ip link down-condition and real link absence (e.g. the switch’s port burned down, or someone tripped over a wire).
By difference I mean some signs in the system that can be used to distinguish these two conditions.
E.g. will routing table be identical in these two cases? Will ethtool or something else show the same things? Is there some tool/utility which can distinguish these conditions?
