I want to move a directory from one host to another. This is my command:

scp -r host1:filepath host2:filepath

I get this error:

ssh: Could not resolve hostname host2: Name or service not known
lost connection

host1 and host2 are present in my ~/.ssh/config, and I can connect to them with ssh host1 and ssh host2 without problem.

Why does scp fail to connect to host2?


I just found that host1 needs to be able to connect to host2 for this to work. The details are in another answer.
