Answer 1

As Tremo already wrote - give up, to the maximum, from the GUI. Console Your friend, comrade and wife. Those. learning bash. All manipulations with files through the console. Vim or nano editor. In any training, the main thing is practice. Take and deploy various servers - DNS, ftp, mailers, application servers (all sorts of apache, Tomcat, Wildfly, nginx), openVPN, XMPP. Make a local network of virtual machines, if possible, you can try on a physical one. Use smb, ssh. Expand LDAP. Databases and their administration is also a plus. You can also deploy and configure TeamCity, GitLab, RedMine. Get to know Docker.
Further, you can also study python for automation.
In the future, you can reach the clusters.
Deepen your knowledge of networks. Books, articles, magazines. On Habré, in general, heaps of everything.
