From my server, connecting to it via eth0 (not localhost), I can connect via SFTP:
Apr 9 10:02:40 domain sshd[11526]:
Accepted password for test from 1.x.x.x port 45335 ssh2
From a remote Filezilla, I cannot connect using the same password:
Apr 9 10:04:25 domain sshd[11531]:
Failed password for test from 2.x.x.x port 26714 ssh2
Both IP addresses are in hosts.allow and the SSH config is properly and setup to allow special ssh and sftp groups to connect.
What could be the error?
I was able to fix this and the answer is so nifty, I thought instead of discarding the question, I'm sharing the solution:
When I connected to my server using putty and root to set a new password for test,
the putty session used ISO-8859-1:1998 (Latin-1, West Europe) encoding. I've put an umlaut in the password which is multibyte in UTF-8, so I had to change the putty session encoding to UTF-8 and change the password again.
I was pretty sure my config is good so I came to this by accident....
Always remember when setting passwords through putty:
ISO täst != UTF-8 täst
