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 protected] #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 192.168.1.3
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?
P.S. - Laptop runs Ubuntu 12.04 & Desktop runs Ubuntu 11.10
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.
