I'm trying to connect to an embedded device through ssh. However, when trying to connect, I always get a connection refused message even when I try changing the port number. I've tried everything to resolve this issue, from changing the file in /etc/ssh/ to accept the specific port number, to sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT .

After reading some comments, it came to me that maybe one of the problems is that I don't have ssh installed on my embedded device. So, how do I infact install ssh on an embedded device? I'm working with a FOX G20 V board with an ATMEL AT91SAM9G20.

I would appreciate any help since I've been stuck on this problem for several days now.

You need to cross compile OpenSSH for your embedded device,Follow below steps

  1. Download OpenSSH from http://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-6.6p1.tar.gz

  2. extract it and cross-compile it using toolchain

    ./configure --host="board architecture"

    make

  3. Copy sshd from compiled source and download it in your embedded device and run it

    /path/sshd
