I am trying to copy my Corosync key from my desktop to my laptop.
sudo scp /etc/corosync/authkey mm-HP-Elit@192.168.0.10:~
What I got is this
ssh: connect to host 192.168.0.10 port 22: No route to host
lost connection
Both of them use the same router in my house.
From my desktop, I am pinging laptop
ping 192.168.0.10

My laptop IP

My idea was to open port 22.

I tried again to open 22
sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT
sudo iptables -A INPUT -p tcp --dport 22 -j ACCEPT
but still I do not see 22 with netstat
netstat -tpln | grep 22
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)

How to resolve this problem?
SOLVED
It was an sshd issue. I purged and installed OpenSSH server.
Best Answer
I don't see SSH port on your netstat result.
Desktop IP: 192.168.0.12
Laptop IP: 192.168.0.10
Need to make sure desktop can ping laptop
If ping succeeds, then telnet to ensure SSH port is available and allowable. (Default SSH port is 22; I don't know whether you changed it on your system.)
Telnet OK --> you can run scp command.
Telnet Not OK --> recheck the SSH service running.
How to check SSH service running?
netstat -tapln | grep 22
