I want to copy public keys to my server from a windows system. And the problem I have is, that I don't get the path to the key. I've tried things like:
ssh-copy-id -i C:/Users/username/.ssh/mykey.pub user@serverIP
ssh-copy-id -i ~/.ssh/mykey.pub user@serverIP
The result is always
No such file or directory
What am I doing wrong? I'm using Git Bash for this on Windows 10
Git's ssh is a version of OpenSSH. You can confirm it by running ssh -V under path\to\git\usr\bin. Here is what it evals on my machine:
OpenSSH_7.7p1, OpenSSL 1.0.2o 27 Mar 2018
ssh-copy-id script internally executes some *nix shell command (like exec, cat, etc. You can find more by opening the one under path\to\git\usr\bin in text mode), so it works only against *nix machines. That's the reason why ssh-copy-id under path\to\git\usr\bin is not a executable file.
According to this issue of PowerShell/Win32-OpenSSH, ssh-copy-id is not supported on Windows.
However, there are some alternative ways to do the same thing:
A powershell version of this answer can be
Get-Content $env:USERPROFILE\.ssh\id_rsa.pub | ssh <user>@<hostname> "cat >> .ssh/authorized_keys"
There is also a python script to do the same thing: ssh-copy-id for Windows.
