I recently 'hardened' two Ubuntu servers using Bastille, and now I get permission denied: scp whenever I try to scp files in.
- SSH login works fine.
- I've tried adding an /scp-dump folder with 777 permissions and still get the same error, so I don't believe it is a permission issue.
Tailing /var/log/auth.log doesn't really give any information, apart from
Oct 1 23:08:39 localhost sshd: Accepted publickey for some-user from [redacted ip] port 49250 ssh2 Oct 1 23:08:40 localhost sshd: Received disconnect from [redacted ip]: 11: disconnected by user
Using the -v flag with scp outputs the following:

Any idea where the permission denied might be coming from, config files I can look into, or other logs I should be looking at?
