That's a very good question.
I hadn't actually noticed the file ipp.txt on my server.
It had one line:
	mary,192.168.5.4
I've no idea where it got this IP address from.
In any case, I changed it to 192.168.5.6
and restarted openvpn on both machines,
but this did not help.

I notice incidentally that in /var/log/messages on my laptop I have:
Apr 11 09:54:54 mary openvpn[1860]: SENT CONTROL [server]:
	 'PUSH_REQUEST' (status=1)
Apr 11 09:54:55 mary openvpn[1860]: 
	PUSH: Received control message: 
	'PUSH_REPLY,route 192.168.5.1,topology net30,ping 10,
	ping-restart 120,ifconfig 192.168.5.6 192.168.5.5'

This seems to suggest that an openvpn connection was established
between the two machines.
I have no idea what topology net30 means.

Actually, I'm not really sure what advantage openvpn would have,
even if it was working, over ssh, which works fine.
So I'm not that upset by failure,
but would like to know for curiosity's sake what the problem is.
