I am doing calculations on a cluster of workers with over ssh with machines on both wifi and wired LAN. I noticed that I am able to connect an ethernet cable to a machine that started the calculations on wifi, and the workers seamlessly transition to the wired port. However, on disconnecting, they don’t seem to pick up the wireless communication again, but also don’t display a broken pipe error. Anyone know why it might work one way and not the other, so to speak?

Julia just uses the network routes that your OS provides, so all of that seamless switching is occuring in the OS kernel, and is effectively invisible to Julia.

I should correct the OP- there is no problem disconnecting with Julia on Linux Mint, you just have to do it from the connections panel.
