Great! Thankl you! I now have a starting point for my questions.

I suspect that it may be the problem, so the problem may in fact be on the computer I want to ssh from, if the Jessie computer cannot see it? Oh! Let us use their names. the computer running Wheezy is called Tux-II. The computer running Jessie is called Eros. > 1.

I can ssh from Eros, but not into it. If I just try to ssh from Tux-II to Eros, I get the error "Could not connect to host 192.168.0.4.". I'm actually "fish"ing, but same difference. I get a more helpful message form ssh: lisi@Tux-II:~$ ssh peter@192.168.0.4 @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ @ WARNING: REMOTE HOST IDENTIFICATION HAS CHANGED! @ @@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@ IT IS POSSIBLE THAT SOMEONE IS DOING SOMETHING NASTY! Someone could be eavesdropping on you right now (man-in-the-middle attack)! It is also possible that a host key has just been changed. The fingerprint for the ECDSA key sent by the remote host is d9:2e:38:29:07:f8:8a:6d:4b:dd:28:60:ad:c9:e5:a3. Please contact your system administrator. Add correct host key in /home/lisi/.ssh/known_hosts to get rid of this message. Offending ECDSA key in /home/lisi/.ssh/known_hosts:3 ECDSA host key for 192.168.0.4 has changed and you have requested strict checking. Host key verification failed. lisi@Tux-II:~$ Previously (under Wheezy) using Fish, I have been getting the first part of the message and asked if I want to accept the new identification. Fish presumably then edited the file. So I need static IPs fast! or a hosts file? I have some learning to do. Static IPs I have no problem over, I just need to do it. It clearly needs to move up my priority list. (New router. reserved MAC numbers not yet set up in teh DHCP section.) I have to go now, but I think you have solved it!! (I hadn't researched how to use ssh itself. :-( I was scared of it. :-( ) Thank you. I'll continue later! I'm most grateful, Tomas.
