在嵌入式设备上安装SSH服务器

我正在尝试通过ssh连接到嵌入式设备.但是，当尝试连接时，即使尝试更改端口号，我也总是收到connection refused消息.从将/etc/ssh/中的文件更改为接受特定的端口号，到"sudo iptables -A INPUT -p tcp --dport ssh -j ACCEPT "，我已经尝试了所有方法来解决此问题.

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 .

在阅读一些评论后，我发现也许的问题之一是我的嵌入式设备上没有安装ssh.那么，如何在嵌入式设备上实际安装ssh?我正在使用带有ATMEL AT91SAM9G20的FOX G20 V板.

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.

自从我在这个问题上待了好几天以来，我将不胜感激.

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