Versions

[8.2.2] - 2024-03-18

• The HwType is now added to the json file per router as a new key.

[8.2.1] - 2024-03-16

• Update of libraries:
  • pandas >= 1.5.2,<=2.0.3
  • netmiko == 4.3.0
• The Timos version is now added to the json file per router as a new key.
• The default hostname is now NA_#, where # is the threadnumber. This changes if the hostname is detected later on.

[8.1.1] - 2023-09-17

• Update to have taskAutom support access to SRLinux devices. A new device type nokia_srl has been included under the DICT_VENDOR general dictionary.
• Netmiko, by default, disables pagination either by using environment no more or environment more false. The FIRST_LINE="" from now on for device type nokia_sros.
  • The device_type md_nokia_sros has been removed from the -dt option.
• 00_report.json now includes timing information.

[8.0.6] - 2023-06-24

• The function fncPrintResults() now created a new data file, 00_faildeDataFile, which is a subset of the original data file. Thisincludes only the devices which have presented errors during exectuion.ssh-tunnels.
• The function checkCredentials() has been refactored to better guide users when dealing with jobTypes.

[8.0.5] - 2023-06-22

• The method fncSshServer() has been refactored. Better detection of problematic connections over ssh-tunnels.

[8.0.4] - 2023-06-22

• The method fncUploadFile() decides between SCP or SFTP depending on the Timos version. If taskAutom cannot detect the Timos version, SCP will be selected.
• The method fncUploadFile() will assume cf3:/ for the remote file, if no CF is specified in the ftpRemoteFilename.

[8.0.3] - 2023-06-02

• The method routerRunRoutine() will search for the string #FINSCRIPT after checking for correctness of execution (ie, majorFailed). If further the execution is incomplete, then the total result will be, following the example, labeled as majorFailed:Incomplete.

[8.0.2] - 2023-06-02

• The profile for the device type nokia_sros and nokia_sros_telnet include now as a last line, a FIN_SCRIPT string #FINSCRIPT. The idea is that the method routerRunRoutine() will check for that string. If not detected, taskAutom will assume that the execution of the script is incomplete, either because the command was not correctly sent over to the router; or because the output received from the router was cut somehow.

[8.0.1] - 2023-05-30

• Using latest version of netmiko, 4.2.0
• Update of the method routerLogin(), to use the new method from netmiko, ConnLogOnly(). If sshDebug is True, then a debug file will be created under logsDirectory with per-thread information.

[7.19.4] - 2023-05-06

• Update function renderCliLine()

[7.19.3] - 2023-05-05

• The global dictionary dictParam has been updated with new default keywords.
• New function buildScripts(dictParam), which can be used when importing taskAutom:
  • from src.taskAutom import taskAutom as ta.
  • dictParam['pluginFilename'] = 'myPlugin.py'
  • dictParam['dataFile'] = 'myData.xlsx'
  • dictParam['xlsSheetName'] = 'tabName'
  • d = ta.buildScripts(dictParam)
  • This will allow to use the same plugins and data files when using taskAutom at the console, but within a python code.

[7.19.2] - 2023-05-03

• Parameter -j/--jobType is now 0 by default.
• Parameter -pt/--pluginType is now show by default.
• The json report file now includes the version of taskAutom.

[7.19.1] - 2023-02-09

• Better inventory file checkinng.
• The class myConnection now receives fewer arguments, namely dictonaries routerInfo and dictParam.
  • routerInfo holds all the necesary arguments to establish the connection towards the router, ie, username and password. But also, now, the pluginScript which is the script to be executed on the router.
  • dictParam holds all the global parameters such as log folder name, logTime, dataFileName, pluginName, sshServers, etc.
  • This change follows this idea: even if an inventory is defined, the pluginScript is created before being sent over to the class by the combination of the dataFilename and the pluginFilename. The idea here is that in the near future, the inventory could establish per-router plugins and/or data files. So in one run of taskAutom, different routers will be executing different scripts.
• The method fncUploadFile() has been modified so that jobTypes 2 and 3 have better control over the sent files via SCP/SFTP.
• The method logData() is better now. Log data is a pandas DataFrame being built from a dictionary, which varies depending on the jobType. The function fncPrintResults() now performs a pd.concat(LOG_GLOBAL).
• The function getListOfRouters() no longer provides, only, a list of routers, but also a list of dictionaries which conform the real inventory. The key in that dictionary is the IP of each and every router with a predefined set of subkeys: username, password, deviceType, useSSHTunnel, readtimeout, jumphost and systemIP.
  • If the the jobType is 2, an extra subkey pluginScript will be added. If jobType 3, a list of tuples with [(locaFile,remoteFile)] will be added. These are the files to be uploaded via SCP/SFTP.
  • If there is an external inventroy file, ie -inv inv.csv, the dictParam['inventory'] will be updated with the information contained inside inv.csv.
• The function verifyInventory() has been modified to return a dictionary which is compatible with the one required by the function getListOfRouters().
• New global dictionary DICT_PARAM which can be used when using taskAutom as an import inside a python code.
• Basic MD-CLI support under Nokia, when using deviceType = md_nokia_sros.

[7.18.3] - 2023-02-02

• Better inventory file checking.

[7.18.2] - 2023-02-01

• New paramter to control log file names -fn/--logFileName.
• Retrieving aux values now tries auxRetry times.

[7.18.1] - 2023-01-30

• Variables obtained through argparse are set to True/False depending on the input being yes/no. So now the treatment is hanlde as a boolen when needed.
• New functionality to bulk updload files through SCP/SFTP.
  • For this a new dataFile structure is needed with the following minimum columns: ip|ftpLocalFilename|ftpRemoteFilename.
• Code reordering.

[7.17.13] - 2023-01-27

• CRON config update.

[7.17.11] - 2023-01-27

• Rename parameter sshMaxLoops in favor of maxLoops.
• Remove paramter telnetTimeout.
  • all timinig is now controlled by delayFactor and/or maxLoops.
• Function connectToRouter() is simpler now:
  • New function routerLogin() which direclty calls ConnectHandler() with the appropiate deviceType.
  • Functions routerLoginSSH() and routerLoginTelnet() no longer needed.
• Function fncWriteToConnection() is simpler now as the connection handler is always Netmiko's ConnectHandler().
• Function fncAuxGetVal() is simpler now.
• Function routerLogout() no longer needed.
• PluginType is now a mandatory parameter and no longer optional.
• If cron is enabled, then strictOrder=no and pluginType=config.
• Function fncSshServer(self, strConn, connInfo, sftp=False) now has an sftp parameter which becomes True when invoked from within fncUploadFile().

• 00_log.cvs report includes now the Timos of the device.
• fncWriteToConnection() implements now a set of try|expect for every possible writing option and returns runStatus,logReason,output. This will allow for every method in the class to write appropriately and hence detect if something happened.
• Both functions routerRunRoutine() and fncAuxGetVal() use now the new version of fncWriteToConnection() which detectes better connection problems when writing. This will also help in detecting nodes with connection problems and log them into 00_log.csv

  • This will help in the future to obatin show output data as JSON format.
• New parameter pluginType, either show or config according Netmiko's documentation
  • Default set to config.
