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
