Also good advice. Thanks, Sven, very helpful. Can you recommend a good modern book on networking? > > So how does one do the same thing with "modern" tools? > > I don't understand the question. Do you mean "systemd-networkd"? I'm indirectly referencing a long-running thread on this list about using ifconfig versus "modern" tools for viewing the current interfaces setup. And just how does one restart the new interfaces with systemctl? If I mess something up, is there any way to ssh into the remote system? Thanks very much for all your help! Best, -Tom
