在嵌入式设备上安装 ssh 服务器 [英] Install ssh server on embedded device

问题描述

我正在尝试通过 ssh 连接到嵌入式设备.但是，在尝试连接时，即使我尝试更改端口号，也总是收到 connection denied 消息.我已经尝试了一切来解决这个问题，从更改 /etc/ssh/ 中的文件以接受特定的端口号，到 sudo iptables -A INPUT -p tcp --dport ssh-j 接受.

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 .

阅读一些评论后，我发现可能的问题之一是我的嵌入式设备上没有安装 ssh.那么，我实际上如何在嵌入式设备上安装 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.

如果我已经被这个问题困扰了好几天，我将不胜感激.

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

推荐答案

您需要为您的嵌入式设备交叉编译 OpenSSH，请按照以下步骤操作

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

1. 从以下位置下载 OpenSSHhttp://ftp.openbsd.org/pub/OpenBSD/OpenSSH/portable/openssh-6.6p1.tar.gz

2. 提取并使用工具链交叉编译

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="电路板架构"

./configure --host="board architecture"

制作

从已编译的源代码中复制 sshd 并将其下载到您的嵌入式设备并运行它

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

/path/sshd

尝试连接您的嵌入式设备

Try to connect with your embedded device
