So today I found out why I couldn't SCP stuff to one of my servers for the last 6 months.

It was a fricking "echo" in the .bashrc script (well, in a script that got sourced in there).

(Read: https://stackoverflow.com/q/...)

Though there's "fun" stuff to be made of this.

When echoing nothing, scp just halts. But when echoing a text, that text acually gets printed for the SSH client ...

$ scp foo host:

Please pay for this service

... ok, maybe not a good idea 🤔
