My Setup




  • Ubuntu server 18.04 on local hardware

  • A laptop from which I want to ssh into the server over local network

My Problem



Every once in a while right after boot, I can ssh into the machine for a few minutes. But most of the time I simply get: connect to host 192.168.0.101 port 22: Connection refused.



On the server



  • I disabled the firewall: sudo ufw disable, but didn't help.


  • Then I checked netstat -nlpt and it told me that sshd is listening on port 22.


On my laptop



  • But then I tried nmap -v -p 22 192.168.0.101 and it told me that port 22 was closed.

I am very confused why netstat and nmap tell me different things. Could it be that my wifi-router is blocking ssh somehow?
