When I'm trying to ssh to my local ubuntu server from the gitbash on my windows machine Im getting this error:

$ ssh 192.168.1.11
ssh: connect to host 192.168.1.11 port 22: Bad file number

Other answers I've found seems to be related to linux-to-linux connetions. I'm newbie here, can you please provide information how to achieve that?

Running nmap -sS 192.168.1.11 -p 22:

C:\Users\Me>nmap -sS 192.168.1.11 -p 22
Starting Nmap 6.40 ( )

Running: ssh -v 192.168.1.11 -p 443:

$ ssh -v 192.168.1.11 -p 443

And even if I edit my .ssh/config like this:

Host ubuntu.dev
Hostname 192.168.1.11
User meubuntu

And connecting to ssh ubuntu.dev It still does not work

I know this is an old question, but it came up sorta high up in the Google search, so, for anyone having troubles for SSH'ing from a Windows to a Linux box, in my case, the problem was that I hadn't installed the SSH server on my Linux Mint machine.

Even if you do have SSH installed (like for connecting to another computers), you need this package to enable receiving connections.

sudo apt-get install openssh-server

From your nmap output

PORT STATE SERVICE
22/tcp filtered ssh

You can see the State of port 22 is set as filtered meaning its being blocked either by your ISP or by some firewall. We can use port 443 for doing ssh which wont be blocked by ISP or firewall as folllows.

ssh -v 192.168.1.11 -p 443

This will connect to ssh using port 443.

For more ways to do this see this question.
