1st:

Starting docker image. Pam Put firewall for TCP port and specific user DNS zone example.com. Apache server Squid Degrade a package Ctrl + w , ctrl +alt + w wasn't working

2nd:

Docker create a docker with nginx:xxx docker was not installed

udev maybe: do somthing with /srv/xxxx or maybe: create some drives

systemd fix issues with mysql without modifying configuration files

Packaging create deb package, tar was provided

samba create filesystem create user xxxxx allow that user

git clone a git repo from gitserver(didn't mention username) at /srv/xxx, ssh has been configured correctly, to /anther/location then do bunch of stuff using git

squid install squid and configure it to take configuration from squid-upstream and then maybe clone to squid-downstream

kernel/random question there's a kernel in /srv/xxxx, make it bootable or installable at bootup. I did it using systemd. I used command to install dpkg --install .... rsyslog install and enable and someother stuff

partition create volume group vgx using /dev/xxx /dev/xxx /dev/xxx with 500 MB. create ...... with slicing 5MB. total of two questions

pam configure pam ssh so that if user tries to login 5 time, it gets refused

Database

Openldap looks like ldap server was already installed. kind of exercise provided by linuxacademy.com

Firewall i)this one may not have to be done using firewall -> disallow user charlie to get or maybe send at tcp/portxxx on computer xxxxx. ii) route traffic from port xxx at internet interface to ip address xx.x.x.x at port xx

LXC it was mentioned they were using lxc for all the machines in the beginning. Create lxc Fxxxx and clone Gxxxx and with or something related to /srv/xxx maybe also boot + not boot with these lxc images

Permission many questions: give permission to directory /xxx/xxx 740 and all the files inside this directory 6xx

Email configure postfix use /xxx/xxx.key to create certificate signing request and put it at /xxx/xxxx use same key and create self signed certificate and put it /xxx/xxx use that ssl key and certificate

Apache install apache configure http to listen on port 123 and https to listen on port 567.

Random question i) failsafe to server xxxxxxx ii do it using only nginx or haproxy

Downgrade downgrade package cesxxxx to last version

NFS create nfs share give ro insecure access to network xx.xx.xx.xx give rw secure access to example.com

DNS install bind configure it so that at-least it's listening at lo create a policy at /etc/bind/zones for example.com

JAVE=xxxx setup environment variable and confirm using ssh

sed Question to do a lot of things with file manipulation, like delete all redundant lines, delete second column, and many more.
