This auto-detection is based on a unique class called **SSHDetect**. Notes ----- The **SSHDetect** class is instantiated using the same parameters than a standard Netmiko connection (see the *netmiko.ssh_dispatacher.ConnectHandler* function). The only acceptable value for the 'device_type' argument is 'autodetect'. The auto-detection is solely based on *SSH_MAPPER_BASE*. The keys are the name of the 'device_type' supported for auto-detection and the value is another dictionary describing how to handle the auto-detection. * "cmd" : The command to send to the remote device. **The command output must not require paging.** * "search_patterns" : A list of regex to compare with the output of the command * "priority" : An integer (0-99) which specifies the confidence of the match above * "dispatch" : The function to call to try the autodetection (per default SSHDetect._autodetect_std) Examples -------- # Auto-detection section >>> from netmiko.ssh_autodetect import SSHDetect >>> from netmiko.ssh_dispatcher import ConnectHandler >>> remote_device = {'device_type': 'autodetect', 'host': 'remote.host', 'username': 'test', 'password': 'foo'} >>> guesser = SSHDetect(**remote_device) >>> best_match = guesser.autodetect() >>> print(best_match) # Name of the best device_type to use further >>> print(guesser.potential_matches) # Dictionary of the whole matching result # Netmiko connection creation section >>> remote_device['device_type'] = best_match >>> connection = ConnectHandler(**remote_device) � N)�ConnectHandler)�BaseConnectionz show systemzAlcatel-Lucent�c �_autodetect_std)�cmd�search_patterns�priority�dispatchz show versionZNokiaZAlcatelZApresiaZAristaz!Cisco Adaptive Security Appliancez Cisco ASAzCisco IOS Softwarez,Cisco Internetwork Operating System Softwarez Cisco Nexus Operating SystemzNX-OSz Cisco IOS XRz#Real Time Operating System Softwarez%Dell Application Software Version: 9z Dell Networking OS Version : 9z#Dell EMC Networking OS10.EnterpriseZ PowerConnectzshow sys versionzBIG-IPzcat /etc/issuezdisplay versionz HPE ComwarezHuawei Technologiesz*Huawei Versatile Routing Platform Software)zJUNOS Software ReleasezJUNOS .+ SoftwarezJUNOS OS KernelzJUNOS Base Versionzuname -a�Linuxz (NetIron|MLX)z SLX-OS Operating System SoftwareZ EdgeSwitch� �_autodetect_remote_versionZ CISCO_WLC)r r r r ZOnyxZ SX_PPC_M460EXzshow copyrightzYamaha Corporationzget system statusZFortiOSzshow system infoz model:\s+PAzSuper Micro Computer)Z alcatel_aosZ alcatel_srosZ apresia_aeosZ arista_eosZ cisco_asaZ cisco_iosZ cisco_nxosZcisco_xrZ dell_force10Zdell_os9Z dell_os10Zdell_powerconnectZf5_tmshZf5_linuxZ hp_comwareZhuaweiZ juniper_junos�linuxZextreme_netironZ extreme_slxZubiquiti_edgeswitchZ cisco_wlcZmellanox_mlnxosZyamahaZfortinetZpaloalto_panosZsupermicro_smisr � c C s i | ]\}}||�qS � r )�.0�k�vr r ��/root/rpmbuild/BUILDROOT/imh-python39-modules-3.9.7-92.el8.x86_64/opt/imh-python/lib/python3.9/site-packages/netmiko/ssh_autodetect.py� <dictcomp>� � r c C s | d S �Nr r ��itemr r r �<lambda>� r r )�keyc C s t t| d d �S )Nr r )�int� cmd_countr r r r r � r c @ sX e Zd ZdZdd� Zdd� Zddd�Zd d � Zd ej d fd d�Z dd ej d fdd�Z d S )� SSHDetecta> The SSHDetect class tries to automatically guess the device type running on the SSH remote end. Be careful that the kwargs 'device_type' must be set to 'autodetect', otherwise it won't work at all. Parameters ---------- *args : list The same *args that you might provide to the netmiko.ssh_dispatcher.ConnectHandler. *kwargs : dict The same *kwargs that you might provide to the netmiko.ssh_dispatcher.ConnectHandler. Attributes ---------- connection : netmiko.terminal_server.TerminalServerSSH A basic connection to the remote SSH end. potential_matches: dict Dict of (device_type, accuracy) that is populated through an interaction with the remote end.

This method will be called for each device_type present in SSH_MAPPER_BASE dict ('dispatch' key).

Parameters ---------- cmd : str The command to send to the remote device after checking cache. search_patterns : list A list of regular expression to look for in the command's output (default: None). re_flags: re.flags, optional Any flags from the python re module to modify the regular expression (default: re.I). priority: int, optional The confidence the match is right between 0 and 99 (default: 99). )z% Invalid input detectedzsyntax error, expectingzError: Unrecognized commandz%Errorzcommand not foundz!Syntax Error: unexpected argumentr r: )r9 r> r? r@ rA ) r$ r r rB r rC r8 rD rE r r r r � s zSSHDetect._autodetect_std)r ) �__name__� __module__� __qualname__�__doc__r( r r6 r9 r> � IGNORECASEr r r r r r r � s ! � % �r )rI r> r4 Znetmiko.ssh_dispatcherr Znetmiko.base_connectionr r, r r1 r r � setdefault�countr0 r+ �objectr r r r r �<module> s< ( ������� ����� ������� � ����������� � 5 �
