I work on my laptop and ssh into my desktop. I use a lot of key based authentication for many servers for work but recently I couldn't login because ssh would pick up and try all the keys and it stops trying before ultimately falling back to password based login. So right now I am using this command:
ssh -X -o PubkeyAuthentication=no email@example.com #deskto
The issue is after sometime the desktop would just become unreachable from laptop. I won't be able to open its localhost through IP and today I tried ping'in it and found a weird thing. Instead of
192.168.1.4, it tries to ping
192.168.1.3 which I am sure is the root cause as it just can't reach
192.168.1.4 when its actually trying for
Ping command output:

Also the ping command message comes in multiple and not one by one. (izx answer's the weirdness I thought there was in ping command.)
I did check for desktop, its local IP is still the same, so something is going on in my laptop. Any ideas?
Laptop runs Ubuntu
Desktop runs Ubuntu
Laptop is connected through wifi to router and Desktop is connected through LAN to router.
Update: Even after setting up static IP leases in router settings, I again ran into this issue.
