插入一个 U 盘测试一下 USB

4. 配置网络

由于 IP 绑定了 MAC，所以得克隆 MAC 地址。这里隐去真实地址。

ifconfig eth0 hw ether 11:22:33:44:55:77
ifconfig eth0 222.205.---.___
ip rou add 10.0.0.0/8 via 222.205.---.1 dev eth0

测试与校网的连通性。

root@Acadia:~# ping 10.10.0.21
PING 10.10.0.21 (10.10.0.21) 56(84) bytes of data.
64 bytes from 10.10.0.21: icmp_req=1 ttl=60 time=8.32 ms
64 bytes from 10.10.0.21: icmp_req=2 ttl=60 time=0.363 ms
^C
--- 10.10.0.21 ping statistics ---
2 packets transmitted, 2 received, 0% packet loss, time 1001ms
rtt min/avg/max/mdev = 0.363/4.343/8.323/3.980 ms

配置 DNS 服务，直接修改 Debian 发行版提供的/etc/network/interfaces就行。同时一并把静态 IP 也写进去了。

auto eth0
iface eth0 inet static
address 222.205.---.___
netmask 255.255.255.0
gateway 222.205.---.1
dns-nameservers 10.10.0.21

配玩之后重启服务后发现无法解析域名，看了下/etc/resolve.conf居然没有软连接到/tmp/resolve.conf.auto，干脆就手动修改吧。

nameserver 10.10.0.21

这时候尝试 ping 一个域名，域名解析也没问题了。

root@Acadia:/etc/network# ping who.tao-j.com
PING who.tao-j.com (10.214.---.___) 56(84) bytes of data.
64 bytes from 10.214.---.___: icmp_req=1 ttl=59 time=0.610 ms

64 bytes from 10.214.---.___: icmp_req=4 ttl=59 time=0.560 ms

rtt min/avg/max/mdev = 0.534/0.576/0.610/0.030 ms
root@Acadia:/etc/network#

ssh到 who.tao-j.com 所对应的服务器上，回ping这台设备。其实不用这步也已经证明了两者的互通。

tao-j@d-mint ~ $ ping 222.205.---.___
PING 222.205.---.___ (222.205.---.___) 56(84) bytes of data.

rtt min/avg/max/mdev = 0.574/0.585/0.612/0.013 ms

5. 看下 SSH 配置文件

准确说应该是 sshd 配置文件/etc/ssh/sshd_config

root@Acadia:/etc/ssh# vim sshd_config

以下配置打开端口 22，使用指定的 key。其实这一开始就配好了。

Port 22

Protocol 2
# HostKeys for protocol version 2
HostKey /etc/ssh/ssh_host_rsa_key
HostKey /etc/ssh/ssh_host_dsa_key

两种最基本的 SSH 登入方式

1.直接连接该板配好的静态 IP，会跳出请求输入密码。板子一开始得用 passwd 设置一个密码，空密码没发登入。

tao-j@d-mint ~ $ ssh root@222.205.---.___
root@222.205.---.___'s password:
....

2.使用 rsa-key pair。首先在客户机上生成一个 rsa keypair，并将 public key 填写到开发板相应用户 home folder 的.ssh/authorized_keys中。

root@Acadia:~# cd .ssh/
root@Acadia:~/.ssh# vim authorized_keys

现在使用 ssh 连接板子不用再输密码了。

ying@d-mint ~ $ ssh root@222.205.---.___
Welcome to Linaro 12.11 (GNU/Linux 3.0.35-2666-gbdde708 armv7l)
....

6. 查看登入用户

一个用户是串口，一个用户从 ssh 登入，还有一个 bash，应该是 mux 到了 ttymxc0。

root@Acadia:~# w
 08:05:56 up 5 min,  3 users,  load average: 4.14, 2.99, 1.40
USER     TTY      FROM              LOGIN@   IDLE   JCPU   PCPU WHAT
root     ttymxc0                   08:02    0.00s  0.13s  0.04s w
root     tty1                      08:00    5:54   0.05s  0.03s -bash
root     pts/1    10.214.---.___   08:05   50.00s  0.07s  0.07s -bash

用户间通信

先建立一个新的用户user1，用useradd会很惨，还是用adduser方便点。

root@Acadia:~# adduser user1
Adding user `user1' ...
Adding new group `user1' (1002) ...
Adding new user `user1' (1001) with group `user1' ...
Creating home directory `/home/user1' ...
Copying files from `/etc/skel' ...
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
Changing the user information for user1
Enter the new value, or press ENTER for the default
        Full Name []:
        Room Number []:
        Work Phone []:
        Home Phone []:
        Other []:

测试下write，在 ssh 端执行这个。

root@Acadia:~# write user1
write: write: you have write permission turned off.

hi
hello
bye
really bye
root@Acadia:~#

Check 一下串口端的输出。

user1@Acadia:~$
Message from root@Acadia on pts/1 at 03:01 ...
hi
hello
bye
really bye
EOF

同时还试试wall talk mesg [-n] [-y]命令，不详述了。
