1、生成本地密钥对

密钥保存在交换机中单不保存在配置文件中

[Huawei]rsa ?

key-pair RSA key pair

local-key-pair Local RSA public key pair operations

peer-public-key Remote peer RSA public key configuration

[Huawei]rsa local-key-pair ?

create Create new local public key pairs

destroy Destroy the local public key pairs # 销毁本地密钥对

[Huawei]rsa local-key-pair create

The key name will be: Huawei_Host

The range of public key size is (512 ~ 2048).

NOTES: If the key modulus is greater than 512,

it will take a few minutes.

Input the bits in the modulus[default = 512]:1024 # 密钥对长度越大,密钥对安全性就越好,建议使用最大的密钥对长度

Generating keys...

.......++++++

.++++++

........................++++++++

[Huawei]dsa local-key-pair ?

create Create a new local key-pair

destroy Destroy the local key-pair

[Huawei]dsa local-key-pair create

Info: The key name will be: Huawei_Host_DSA.

Info: The key modulus can be any one of the following : 512, 1024, 2048.

Info: If the key modulus is greater than 512, it may take a few minutes.

Please input the modulus [default=512]:1024

[Huawei]

2、打开STelnet服务器功能

[Huawei]stelnet server enable

3、配置SSH服务器端口号

[Huawei]ssh server port ?

INTEGER<22,1025-55535> Set the port number, the default value is 22

4、配置密钥对更新时间

[Huawei]ssh server rekey-interval ?

INTEGER<0-24> Set the interval (in hours), the default value is 0, which means the server will not generate the new key automatically

5、配置SSH认证超时时间

[Huawei]ssh server timeout ?

INTEGER<1-120> Set the authentication timeout, the default value is 60 seconds

6、配置SSH认证重试次数

配置SSH认证重试次数用来设置SSH用户请求连接的认证重试次数,防止非法用户登录。

[Huawei]ssh server authentication-retries ?

INTEGER<1-5> Set the authentication times, the default value is 3 times

7、使能兼容低版本SSH协议

[Huawei]ssh server compatible-ssh1x ?

enable Enable or disable the compatibility with SSH1, the default value is enabled

8、配置SSH服务器的源接口

指定SSH服务器端的源接口前,必须已经成功创建LoopBack接口,否则会导致本配置无法成功执行。

[Huawei]ssh server-source -i ?

<NULL> Not exists loopback interface

9、配置访问控制列表

[Huawei]ssh server acl 2001

10、配置通过SSH登陆的帐号密码

具体配置见VTY配置

11、配置VTY用户界面支持SSH协议

[Huawei-ui-vty0-4]protocol inbound ?

all All protocols

ssh SSH protocol

telnet Telnet protocol

12、创建SSH用户

[Huawei]ssh user ?

STRING<1-64> The specified user name

[Huawei]ssh user 1

Info: Succeeded in adding a new SSH user.

[Huawei]

13、配置SSH用户的认证方式

[Huawei]ssh user 1 ?

assign Set the key

authentication-type Authentication type

authorization-cmd Authorization mode

service-type Set service type

sftp-directory Set SFTP directory

<cr>

[Huawei]ssh user 1 authentication-type ?

all Any authentication mode, any one of password, RSA, and DSA

dsa DSA authentication

password Password authentication

password-dsa Both password and DSA authentication modes

password-rsa Both password and RSA authentication modes

rsa RSA authentication

如果没有使用ssh user命令配置相应的SSH用户,则可以直接执行ssh authentication-type default password命令为用户配置SSH认证缺省采用密码认证,在用户数量比较多时,对用户使用缺省密码认证方式可以简化配置,此时只需再配置AAA用户即可。

14、配置SSH用户的服务类型

[Huawei]ssh user 1 service-type ?

all Set all service type

sftp Set SFTP service type

stelnet Set Stelnet service type

[Huawei]ssh user 1 service-type stelnet

15、配置SSH用户按命令行授权,即只能通过命令行使用

[Huawei]ssh user 1 authorization-cmd ?

aaa Set the AAA authorization mode

password认证依靠AAA实现,当用户使用password、password-rsa或password-dsa认证方式登录设备时,需要在AAA视图下创建同名的本地用户。

如果SSH用户使用password认证,则只需要在SSH服务器端生成本地RSA或DSA密钥。

如果SSH用户使用RSA或DSA认证,则在服务器端和客户端都需要生成本地RSA或DSA密钥对,并且服务器端和客户端都需要将对方的公钥配置到本地。

16、对SSH用户进行password、password-dsa或password-rsa认证时在AAA下创建同名用户名

[Huawei-aaa]local-user 1 password irreversible-cipher 023wg.com

17、对SSH用户进行dsa、rsa、password-dsa或password-rsa认证时配置方法

17.1、进入RSA或DSA公共密钥视图

[Huawei]rsa peer-public-key 023wg.com

Enter "RSA public key" view, return system view with "peer-public-key end".

[Huawei-rsa-public-key]

[Huawei]dsa peer-public-key ?

STRING<1-30> Name of the peer public key

[Huawei]dsa peer-public-key 1 ?

encoding-type Encoding type of the remote peer's public key

[Huawei]dsa peer-public-key 1 encoding-type ?

der DER encoded public key # DER编码的公钥

pem PEM encoded public key # PEM编码的公钥

[Huawei]dsa peer-public-key 1 encoding-type der ?

<cr>

[Huawei]dsa peer-public-key 1 encoding-type der

Info: Enter "DSA public key" view, return system view with "peer-public-key end"

.

[Huawei-dsa-public-key]

17.2、编辑公共密钥

[Huawei-rsa-public-key]public-key-code ?

begin Begin to input public key code

[Huawei-rsa-public-key]public-key-code begin ?

<cr>

[Huawei-rsa-public-key]public-key-code begin

Enter "RSA key code" view, return last view with "public-key-code end".

[Huawei-rsa-key-code]

17.3、编辑公共密钥

键入的公共密钥必须是按公钥格式编码的十六进制字符串,由支持SSH的客户端软件生成。请将获取的RSA或DSA公钥输入到作为SSH服务端的设备上。

[Huawei-rsa-key-code]30820108 02820101 00DD8904 1A5E30AA 976F384B 5DB366A7

[Huawei-rsa-key-code]048C0E79 06EC6B08 8BB9567D 75914B5B 4EA7B2E5 1938D118

………………………………………………………………………………………………………

[Huawei-rsa-key-code]4B863A38 BA7E0F0D BE5C5AE4 CA55B192 B531AC48 B07D21E3

[Huawei-rsa-key-code]1B020125

[Huawei-rsa-key-code]

17.4、退出公共密钥编辑视图

[Huawei-rsa-key-code]public-key-code end

% Fail to decode key string, the key string may be invalid.

[Huawei-rsa-public-key]

17.5、退出公共密钥视图

[Huawei-rsa-public-key]peer-public-key end

[Huawei]

17.6、为SSH用户分配RSA或DSA公钥

[Huawei]ssh user 023wg.com assign dsa-key 023wg.com
