The majority of gnu/linux source code files come as compressed tar files.
mypackage.tar.gz anotherpackage.tar.bz2, somethingelse.tar.xz or even thingy.tgz
You will have to download these files, then uncompress them, then untar them.
The files in /proc aren't always "normal" files.
Normally you don't "tail" a process. You want to tail output from a file (usually one that has streaming input).
tail -f /opt/mylogfile.log is probably what you want to do here.
Every time a process is restarted it will have a different...
In this case, if the clients are out of your control, I would set the lease time to a pretty long time.
In your dhcpd.conf file you have something that looks like this...
# Sample configuration file for ISC dhcpd
# option definitions common to all supported networks...
Which dhcp server are you using? dhcpd? dnsmasq?

Usually the lease will get give out the same address as the last lease had for that MAC.
If you aren't...
A few comments about this.
"Most" (not all) distros keep history since the last reboot.
However the scroll-back buffer in your console/terminal may truncate the output.
Some distro's rotate the history every so often, but you can change this.
Another thing to keep in mind, is not every has...
I would agree the RHCE (RedHat) is probably the most valuable. I am RHCE myself.
Over the last 25 years or so I've worked for a dozen different IT companies. The vast
majority of them are Redhat/CentOS shops. Depending on which website you believe they
own over 90% of the Linux server...
That's kind of a trick question.
As a rule, "major version" updates do. from 4.4.1 to 4.5.1 would. 5.5.2 to 5.6.2 would.
However minor versions typically do not. They only patch bugs and do security patches
for existing drivers.
4.4.10 to 4.4.11 only has patches and bug fixes for...
