I have a Fedora- Raspi setup to run Rak-Gateway
Router 192.168.0.1
Fedora 192.168,0,103
Raspi 192.168.0.100
POE (Power Over Ethernet) to power Raspi-Rak gateway.
I'm not well up to date on how to make changes in a Debian computer so please take that into consideration.
I'm mainly a RPM Guy.
On Networking: I have setup in Router, DHCP/Address Reservations, both the Raspi-3+ and Fedora-28.
But I cannot get the raspi to showup in Router/DHCP/Client List
So I cannot get the Raspi to get onto the internet.
Raspi can Ping Router-192.168.0.1 and Fedora 192.168.0.103, but can't get onto Internet.
SSH Problem: I can;t get to that until I get the Networking problem fixed.
[root@mickey mickey]# ssh pi@192.168.0.100 ( Command run from Fedora)

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
SHA256:MLqV6aSf8hJzYninnEDNesULP76++6VAlYWG9qSTkwM.
Please contact your system administrator.
Add correct host key in /root/.ssh/known_hosts to get rid of this message.
Offending ECDSA key in /root/.ssh/known_hosts:2
ECDSA host key for 192.168.0.100 has changed and you have requested strict checking.
Host key verification failed.
(Run from Raspi)
/root/.ssh/known_hosts and host2 (No such file or directory) in Raspi.)
Known _hosts- is that setting in the Raspi ?
What Host would that be.
From what I can see is, SSH is not setting up on Raspi.
I have been working in the Router so I think the first half of this message has to do with that.
If I type hostname in raspi it comes back with "rak-gateway" without quotes
What is command in Debian for Change Directory , (cd) in Fedora. In Raspi it says sudo cd command not found. (BOY!!!, This is getting Crazy).
