技术领域technical field
本发明涉及通信技术领域，特别是涉及一种基于开源安全外壳协议的登录方法及登录系统。The invention relates to the field of communication technology, in particular to a login method and a login system based on an open source secure shell protocol.
背景技术Background technique
安全外壳协议(Secure Shell，SSH)是目前较可靠，专为远程登录会话和其他网络服务提供安全性的协议。利用SSH协议不仅可以有效防止远程管理过程中的信息泄露问题，还可以压缩传输的数据，加快传输的速度。SSH有很多功能，它既可以代替Telnet，又可以为FTP、PoP、甚至为PPP提供一个安全的“通道”。Secure Shell (SSH) is currently a more reliable protocol that provides security for remote login sessions and other network services. Using the SSH protocol can not only effectively prevent information leakage in the remote management process, but also compress the transmitted data to speed up the transmission. SSH has many functions, it can not only replace Telnet, but also provide a secure "channel" for FTP, PoP, and even PPP.
诸如交换机等网络设备系统都有自己定制的命令行界面(command-lineinterface，CLI)配置界面。用户通过SSH登录时进入的是嵌入式设备系统定制的CLI配置界面，而不是linux系统的shell界面。A network device system such as a switch has its own customized command-line interface (command-line interface, CLI) configuration interface. When users log in through SSH, they enter the CLI configuration interface customized by the embedded device system instead of the shell interface of the linux system.
目前国内，除少数几家研发实力较强的公司会自己实现SSH协议外，大部分的网络设备研发厂商都是基于开源SSH软件(如OpenSSH)，针对自身系统做适配修改开源软件的源码来实现SSH用户认证登陆功能。At present, in China, except for a few companies with strong R&D capabilities that will implement the SSH protocol themselves, most network equipment R&D manufacturers are based on open source SSH software (such as OpenSSH), and adapt and modify the source code of the open source software for their own systems. Realize the SSH user authentication login function.
然而，若公司自己实现SSH协议的开发，不使用开源软件，这个研发成功高，仅适合少数有一定研发实力的公司。而众多公司利用开源SSH软件(如OpenSSH)，针对自身系统做适配修改开源软件的源码来实现SSH用户认证登陆功能。但是，目前因为要修改开源软件源码，需要对开源软件的源码进行学习，后续升级开源软件版本或者更换开源软件、系统维护人员的成本高。However, if the company realizes the development of the SSH protocol by itself and does not use open source software, the success of this research and development is high, and it is only suitable for a small number of companies with certain research and development capabilities. And many companies use open source SSH software (such as OpenSSH) to adapt and modify the source code of the open source software for their own systems to realize the SSH user authentication login function. However, at present, because the source code of the open source software needs to be modified, it is necessary to learn the source code of the open source software, and the cost of subsequently upgrading the open source software version or replacing the open source software and system maintenance personnel is high.
因此，如何在不增加成本的基础上实现SSH用户的登录功能就成为本领域技术人员亟待解决的问题之一。Therefore, how to implement the login function of the SSH user without increasing the cost has become one of the problems to be solved urgently by those skilled in the art.

正如背景技术中所述的，目前通过SSH进行登录时，要么自己开发SSH协议，要么利用开源SSH软件来实现，但是无论哪种方式，开发的成本都很高，应用的范围非常受限。As mentioned in the background technology, when logging in through SSH, one must either develop the SSH protocol by oneself or use open source SSH software to realize it, but either way, the development cost is very high, and the scope of application is very limited.
请参阅图1，本发明提供一种基于开源安全外壳协议的登录方法，所述基于开源安全外壳协议的登录方法包括以下步骤：Please refer to Fig. 1, the present invention provides a kind of login method based on open source secure shell protocol, described login method based on open source secure shell protocol comprises the following steps:
S11，向开源安全外壳协议应用模块发送系统用户信息；S11, sending system user information to the open source secure shell protocol application module;
S12，Linux内核模块对所述系统用户信息进行验证；S12, the Linux kernel module verifies the system user information;
S13，当Linux内核对所述系统用户信息验证通过后，执行重定向应用模块以实现登录。S13. After the Linux kernel passes the verification of the system user information, execute the redirection application module to implement login.
具体地，用户通过SSH客户端软件(如SecureCRT)请求与OpenSSH建立SSH连接，在此过程中向OpenSSH发送SSH用户名和密码。Specifically, the user requests to establish an SSH connection with OpenSSH through SSH client software (such as SecureCRT), and sends the SSH user name and password to OpenSSH during the process.
OpenSSH向linux查询用户名是否存在及用户名的密码是否正确，如果不正确，拒绝用户的连接请求，否则进行下一步处理。具体地，linux系统内核(linux kernel)对用户名及密码进行验证。OpenSSH queries linux whether the user name exists and whether the password of the user name is correct. If it is incorrect, the user's connection request is rejected, otherwise, the next step is processed. Specifically, the linux system kernel (linux kernel) verifies the user name and password.
OpenSSH在得知用户认证通过后，执行RdirectIO应用程序(该应用程序为预开发的重定向应用模块)。OpenSSH在执行RdirectIO时进行重定向，从而实现SSH用户的登录。RdirectIO是本实施例中需要实现的一个应用程序，其功能参考后面的描述。OpenSSH executes the RdirectIO application program (this application program is a pre-developed redirection application module) after learning that the user authentication is passed. OpenSSH performs redirection when executing RdirectIO, so as to realize the login of SSH users. RdirectIO is an application program that needs to be implemented in this embodiment, and its functions refer to the following description.
在本实施例中，所述执行重定向应用模块以实现登录的步骤包括：在所述重定向应用模块与Linux内核之间建立重定向SSH连接；在所述重定向应用模块与预制命令行界面之间建立TCP连接以实现登录。具体地，在所述重定向应用模块与预制命令行界面之间建立长TCP连接。In this embodiment, the step of executing the redirection application module to realize login includes: establishing a redirection SSH connection between the redirection application module and the Linux kernel; Establish a TCP connection between them to achieve login. Specifically, a long TCP connection is established between the redirection application module and the prefabricated command line interface.
在实际应用中，OpenSSH在执行RdirectIO时，创建一个管道(pipe)。通过这个管道，RdirectIO的标准IO会重定向到ssh连接。同时，RdirectIO与系统定制CLI建立一条tcp连接，把RdirectIO的标准IO重定向到这条tcp连接。In practical applications, OpenSSH creates a pipeline (pipe) when executing RdirectIO. Through this pipeline, RdirectIO's standard IO will be redirected to the ssh connection. At the same time, RdirectIO establishes a tcp connection with the system custom CLI, and redirects the standard IO of RdirectIO to this tcp connection.
也就是说，RdirectIO的功能是将系统定制CLI的输入重定向到RdirectIO标准输出；同样，将RdirectIO的标准输入重定向到系统定制CLI的输出，这样就可以通过在系统定制CLI与RdirectIO之间建立TCP长连接来实现这里的IO重定向功能。In other words, the function of RdirectIO is to redirect the input of the system custom CLI to the RdirectIO standard output; similarly, redirect the standard input of RdirectIO to the output of the system custom CLI, so that it can be established between the system custom CLI and RdirectIO TCP long connection to realize the IO redirection function here.
具体地，所述RdirectIO的实现代码为：Specifically, the implementation code of the RdirectIO is:
经过上述两步IO重定向(Input&Output)处理，SSH用户通过SSH认证登录系统后，在SSH客户端(如SecureCRT)上输入的数据经过两次重定向到达系统CLI界面；反之，系统定制CLI输入的数据也经过两次重定向到达SSH客户端。After the above two-step IO redirection (Input&Output) processing, after the SSH user logs in to the system through SSH authentication, the data input on the SSH client (such as SecureCRT) is redirected twice to the system CLI interface; otherwise, the system custom CLI input Data is also redirected twice to the SSH client.
虽然实际上用户在SSH连接上输入的数据是先经过OpenSSH解密，解密后的数据经过两次重定向才到达系统定制CLI。但是，在系统使用用户的感知上，用户是直接进入了系统定制CLI界面。在系统使用者的感知上，用户是直接登录到了系统定制CLI界面。Although in fact the data entered by the user on the SSH connection is first decrypted by OpenSSH, the decrypted data is redirected twice before reaching the system customization CLI. However, in terms of the user's perception of the system, the user directly enters the system customization CLI interface. From the perspective of system users, the user is directly logged in to the system custom CLI interface.
为了实现系统用户信息的验证，在本实施例中，所述基于开源安全外壳协议的登录方法还包括：在登录Linux系统后，向Linux内核中添加系统用户信息，所述系统用户信息包括：用户名和密码。In order to realize the verification of system user information, in this embodiment, the login method based on the open source security shell protocol also includes: after logging into the Linux system, adding system user information to the Linux kernel, the system user information includes: user name and password.
具体地，所述向Linux内核中添加系统用户信息的步骤包括：Linux内核将所述系统用户信息保存在/etc/shadow和/etc/passwd文件夹中。同时，Linux内核将所述系统用户信息保存在/etc/passwd文件夹中时，在所述/etc/passwd文件夹中指定系统用户信息验证通过后的执行程序为所述重定向应用模块。Specifically, the step of adding system user information to the Linux kernel includes: the Linux kernel saves the system user information in /etc/shadow and /etc/passwd folders. At the same time, when the Linux kernel saves the system user information in the /etc/passwd folder, the execution program after the verification of the system user information is specified in the /etc/passwd folder is the redirection application module.
在实际应用中，开源OpenSSH的用户认证是向linux kernel(Linux内核)校验用户名及其密码的正确性。用户通过串口登录系统，在向系统添加SSH用户时同时向linuxkernel添加相同用户名及密码的系统用户。Linux系统将系统用户及其密码保存在“/etc/shadow”和“/etc/passwd”两个文件中。In practical applications, the user authentication of open source OpenSSH is to verify the correctness of the user name and its password to the linux kernel (Linux kernel). Users log in to the system through the serial port, and when adding an SSH user to the system, add a system user with the same user name and password to the linuxkernel at the same time. The Linux system saves system users and their passwords in two files, "/etc/shadow" and "/etc/passwd".
例如，用户为交换机增加了名为admin的用户，交换机系统在将用户添加到自身的配置文件中时，向linux kernel增加一个名为admin的系统用户。系统用户增加成功后在“/etc/shadow”和“/etc/passwd”两个文件中各增加了一条记录。在往“/etc/passwd”文件添加admin用户的记录时，最后一个“:”后面填写的内容是OpenSSH在确定用户名及密码都正确后要执行的应用程序，这里填写的是RdirectIO应用程序。For example, a user adds a user named admin to the switch, and the switch system adds a system user named admin to the linux kernel when adding the user to its own configuration file. After the system user is successfully added, a record is added in the two files of "/etc/shadow" and "/etc/passwd". When adding the admin user record to the "/etc/passwd" file, the content filled after the last ":" is the application that OpenSSH will execute after confirming that the user name and password are correct, and the RdirectIO application is filled here.
具体的，shadow文件的实现代码为：Specifically, the implementation code of the shadow file is:
#cat/etc/shadow#cat /etc/shadow
Root:5Gg.mRfhg Iz4g:10925:0:99999:7:::Root:5Gg.mRfhg Iz4g:10925:0:99999:7:::

Admin:IjU5ugwlS2HnY:15357:0:99999:7:::Admin:IjU5ugwlS2HnY:15357:0:99999:7:::
##
passwd文件的实现代码为：The implementation code of the passwd file is:
#cat/etc/passwd#cat /etc/passwd
Root:x:0:0:root:/root？/bin/shRoot:x:0:0:root:/root? /bin/sh
Sshd:x:1000:1000:sshd privsep:/var/empty:/bin/sshSshd:x:1000:1000:sshd privsep:/var/empty:/bin/ssh
Admin:x:1001:1001:Linux User,,,:/home:/mnt/app/RdirectIOAdmin:x:1001:1001:Linux User,,,:/home:/mnt/app/RdirectIO
##
OpenSSH在执行RdirectIO应用程序时会在OpenSSH与RdirectIO之间创建一条管道(pipe)。用户在SSH客户端(如SecureCRT)上输入的数据经过OpenSSH解密后通过这条管道直接到达RdirectIO。反过来，RdirectIO的标准输出也通过这条管道经OpenSSH加密后输出到SSH客户端。这里的处理由OpenSSH开源软件完成，不需要修改OpenSSH源码。When OpenSSH executes RdirectIO applications, it will create a pipeline (pipe) between OpenSSH and RdirectIO. The data entered by the user on the SSH client (such as SecureCRT) is decrypted by OpenSSH and directly reaches RdirectIO through this pipeline. Conversely, the standard output of RdirectIO is also encrypted by OpenSSH through this pipeline and output to the SSH client. The processing here is done by the OpenSSH open source software, and there is no need to modify the OpenSSH source code.
本实施例的基于开源安全外壳协议的登录方法，通过预制的重定向应用模块完成两次重定向，从而实现SSH用户的登录，并且不需要开源SSH源码，因此，大大降低了后续升级或者运营维护的成本。The login method based on the open source secure shell protocol of this embodiment completes two redirections through the prefabricated redirection application module, thereby realizing the login of the SSH user, and does not require open source SSH source code, therefore, greatly reducing subsequent upgrades or operation and maintenance the cost of.
