Debian based OS's have a similar issue as the behavior in RHEL/CentOS dhclient, which is that if you have an interface that relies on DHCP, if the first attempt fails, it will quit and stop. This is a problem especially if you are using your Linux as a router or something else mission critical, but where the internet for some reason may have been down or the DHCP server it gets a lease from broken.
The expected behavior you would hope is that when things are back online that the........
Kubernetes Easy Beginners Architecture Guide
Kubernetes is known as container orchestration and we should start at explaining the container part of it.
A Container is what runs the actual application and based on an Image, and are more comparable to something like an LXC Container, Virtuozzo/OpenVZ using the Linux Kernel Namespaces feature. Containers run these images as independent, isolated operating environments under the OS's exist........
How Do You Apply Changes You've Made?
You can make all kinds of changes to the switch, but remember they are not actually active until you run the "commit" command. This means adding or deleting config options will not have any effect until you run "commit".
Under configure mode:
Traditionally kernels were numbered starting from 0 but by default the "new style" of grub boot loading considers each subkernel item to be different so if you have 3 entries for 4.40-148 rather than counting for 1.
To get the expected behavior let's show this example and how we can boot it
We do a grep on menuentry in /boot/grub/grub.cfg to see all of the bootable kernels rather than scrolling through loads of extra entries we don't care about (thou........

It is fairly simple to use once you know how to use it. However, the tricky thing is that by default it doesn't seem to be active or listen on any interface on manually specified.

You can find many ways to specify the VLANin your network configuration but Ifind this is the simplest and quickest.
In this case we are talking about a bridged adapter "vmbr0" but it works even if you just had a normal non-bridged interface.
The key here is that in vmbr0 you'll notice there is no IP address. We just specify "manual".
Below it is a similar stanza for "vmbr0.58" in this case 58 represents the VLAN (change........
#mount the VCSA DVD
mount /dev/sr0 /mnt/cd
#alternatively you could mount the iso directly
mount -o loop vcsa.iso /your/mount/path
#for this purpose we are using the CLI installer on Linux
#no it's not going to be that easy you can't just run vcsa-deploy like that you need to use a template or configured .json file
Usage: vcsa-deploy [-h] [--version] [--supported-deploymen........
This works for almost all ISO's Ifind (at least Linux based):
sudo dd if=CentOS-6.9-x86_64-minimal.iso of=/dev/sdg bs=20M
20+1 records in
20+1 records out

Of course change the .iso filename above and the /dev/sdg to your desired USB drive!........

I was getting very frustrated one day wondering why it appeared my .htaccess file was being ignored and not processed by Apache. No matter what I did it was obvious that Apache didn't care about my .htaccess file. Then I realized that the default settings must be in effect, which is that my vhost didn't explicitly allow me to override the default settings.
This usually comes down to your vhost settings. Make sure you have an entry like this in your Apache vhost settings in........
Server not using user level security and no password supplied.
tree connect failed: NT_STATUS_WRONG_PASSWORD
That happens when trying to use smbclient to connect to a share. The weird thing is that I can authnenticate just fine from Windows XP.
It is partially my mistake, I forgot this share does have a password. I've tried authenticating with the correct user and also with "Guest" because this works in Windows. In Linux I ........
