When uninstalling software you compiled yourself you can run make -n install to see what the make install command did. For Nginx you only had to remove /sbin/nginx before installning NginX from YUM.
# make -n install
make -f objs/Makefile install
make: Entering directory `/root/install/cache/nginx-1.9.9'

Default in varnish 5.2.1 keepalive is enabled, and set with a timeout of timeout_idle=5 seconds. which means that if no traffic goes through the tcp pipe in 5 seconds the TCP connection is closed.
If you are running HLS with a chunksize of 8 seconds you want to change timeout_idle to 8 seconds. you can change timeout_idle in a default installation by adding the following to /etc/varnish/varnish.params.
To add a second ip-number to an network interface create a new ifcfg file ex /etc/sysconfig/network-scripts/ifcfg-enp1s0f0:0
The default configuration for that interface might have parameters such as UUID, NAME those are not needed. change ONBOOT to yes after testing the configuration. To test run.
systemctl restart network.service
The goal is to allow root to login with username/password from local IP-addresses. But only allow root to login with public key authentication from internet.
First change the following settings in /etc/ssh/sshd_config. this will allow normal users to login with username/password but root users must use public key authentication.
Second, add the following to the end of /etc/ssh/sshd_config. Its important that you are in the end of the file because how sshd_config is read by the daemon.

after haveged is installed /proc/sys/kernel/random/entropy_avail should return something above 1000.
yum install -y epel-release
yum install -y rng-tools haveged
systemctl enable haveged.service
systemctl start haveged.service
systemctl status haveged.service
cat /dev/random | rngtest -c 1000
Shuttle DS77u, DS67u and DS57u has problem booting without a monitor then upgrading from PfSense 2.3 to 2.4. These devices ran Legacy bios and not UEFI (UEFI is a new feature in PfSense 2.4) but never booted if the sceen was disconnected at power on, and never initialized the screen if plugged in after power on. This was because the serial ports were enabled in bios.
Bleupomme on PfSense Forum had the answer.
This just happened to me too on a shuttle XPC:
– Updated the BIOS, but this did not solve the problem
– Brute forced BIOS settings
-> by disabling the Serial ports the computer boots normally
Does pfsense 2.4 default to Serial and wait for some sort of connection when there is no monitor?
Heres some tips and trix for setting up an named server on CentOS 7.
This these guides configure your postfix so its forwards all local mails to an external server using authentication.
I Recently updated my OP5 machine later after an reboot got the error message. Important to know is that i run my VM (Virtual Machine) on a headless server so i have no more tools then to VNC to a VM and therefore its hard to get into grub at boot as the timeout was set to 5 seconds.
Kernel panic - not syncing: VFS: Unable to mount root fs on unit block(0,0)
You can use ffprobe to investigate the GOP configuration of a h264 videofile. Some formats require a certain GOP structure to work. In your GOP structure you got I-Frames,P-Frames and B-frames.
