any formal training for SUSE Linux online to learn about networking

I am novice to Linux wanted to know if there is any place where I can learn details about the os// especially about networking and other aspects of the os

I don’t know about formal openSUSE-specific training, but how about some excellent tutorials by swerdna (one of our members and an administrator here):
