Thanks Ralph, looking in /var/log/auth.log was helpful:

Apr 11 19:59:13 localhost sshd[4295]: warning: /etc/hosts.allow, line 
12: missing newline or line too long
Apr 11 19:59:13 localhost sshd[4295]: refused connect from 127.0.0.1 
(127.0.0.1)

The first line adviced me to look again at hosts.allow file. It seems 
that Kate editor had erased the end of lines, and that was the problem.

Thanks again.
