comment 'Slow down' A DHCP server on purpose
I had the same problem once: Our main DHCP server was maintained by another team, by I needed a local boot server which served a pool of 5 IP addresses from a separate address range. Luckily, the main DHCP server was bridged over multiple network components and thus had slower response times. Today, I have a similar problem but also need to slow down the server. The answers for this question are not typical because they all say why it's not good and nobody cares about a real answer

comment what does `pipe <number>` mean in `ping` output?
Btw on some systems, the output is different: my ubuntu shows: 4 packets transmitted, 0 received, +3 errors, 100% packet loss, time 3014ms and pipe 3 in different lines which confused my Java code which tries to parse it

comment ISC DHCPD class is not assigned
This will come later (with a bunch of other settings like dns etc.). For first, I want to keep the example as simple as possible. (Some pages also say it's server-name not next-server which is used as tftp server)

comment ISC DHCPD MAC address matching classes confusion
From first view I see that in the first two class definitions you compare the values and in class pcs you use binary-to-ascii to implement the same thing. But that's not the solution, that's only an inconsistency. I have a very similar problem in my question serverfault.com/questions/715011/…: the classes are just not assigned.

comment How to continue redirecting stdout to a file after logrotate moves it?
This only works if you have explicit output commands like echo. The output of third party tools which are called from the script and also output something cannot be redirected to the logger this way

comment Unprivileged lxc container as root
When trying to do the same, I had the log line: Permission denied - could not access /var/lib/lxc. Please grant it 'x' access, or add an ACL for the container root.. chmod +x /var/lib/lxc/ solved it for me. And instead of lxchostuser:165536:65536 I had root:165536:65536 in /etc/subuid and /etc/subgid

comment How to auto-start unprivileged lxc containers?
Does the crontab approach work? On Ubuntu 14.04, I get the "call to cgmanager_move_pid_sync failed: invalid request" error which occurs because PAM, namely libpam-systemd is not involved in the user changing process. You can see in /proc/self/cgroup that it contains sequences like /user/0.user/1.session instead of /user/1000.user/1.session

comment What is the best practise to autostart unprivileged lxc containers on Ubuntu 14.04 64bit?
I found what's different if you use su/sudo instead of ssh: check the file /proc/self/cgroup. The reason must be somewhere around PAM, namely libpam-systemd. I wrote something about this here: askubuntu.com/questions/623789/…
