Re: What Is The Password Isohunt Verifier

The Command Line Reference guide is better understood if you know the basics of operating the programmable command line interface (PCLI). Commands and actions such as clear, edit, delete, restore, and show, for example, are described here. If you have not used the PCLI before, please refer to About the PCLI for an explanation of how it works.
If you know the ID of the organization in Mist, or the registration code for the router, you can use the optional org-id or registration-code arguments. Otherwise, use the interactive dialog to walk through entering Mist credentials and assigning the router to an organization.
The clear arp command is typically used during troubleshooting to force a refresh of ARP (Address Resolution Protocol) entries from an SSR or node's ARP cache. The command has multiple filters, allowing administrators to specify which entry to refresh. The PCLI auto-completes typed entries for improved accuracy.
The commit command causes the SSR to validate the candidate configuration, and then replace the running configuration with the candidate configuration (assuming it passes the validation step). It is used once a series of configuration changes have been made, and an administrator wishes to "activate" those configuration changes.
When run from an SSR conductor, the conductor only validates the configuration itself locally before committing the configuration and then distributing it to all managed routers. If the user wishes, the conductor has the ability to distribute the configuration to all managed routers for each of them to validate it and report the results of their validation before the commit takes place (assuming a successful validation). This operation is much slower than local validation because the conductor must wait for all routers to report their results and some may be unreachable or timeout. The user may request a distributed validation by using the validate-router-all keyword.
If the validation step fails, the administrator will be notified, the commit step is not executed, and the existing running configuration will remain in place. The validator will get a list of all errors that must be addressed before the commit can be completed. There may also be warnings displayed in the event that the candidate configuration contains elements that are deprecated.
The compare config command presents a list of differences between the two configurations specified as arguments on the command line. The one listed first influences the output in a very important way: the SSR will return a list of configuration commands that will cause the configuration to be listed first to be brought to parity with the one listed second. (Note: since the only editable configuration is the "candidate" configuration, the changes outlined by the compare config command cannot be directly applied to the "running" configuration.)
The ability to specify a previously exported configuration file to compare against the running or candidate config allows you to compare configurations without having to import the exported config into the candidate config for comparison.
The configure command places administrators into the configuration tree (hierarchy), where they will be making changes to the candidate configuration. When entered as a standalone command (i.e., configure by itself), the administrator is placed at the top of the configuration tree.
By supplying optional arguments to the configure command as in the above example, the administrator has entered into the configuration tree at the "router" tier, within the router element named "Fabric128". Not only can administrators enter into the configuration tree at any point through this technique, but new configuration can also applied directly in this same way.
The create certificate request webserver generates a certificate-request, which is then sent to a Certificate Authority. The SSR will, through a series of interactive prompts, request information from the administrator to generate either the request or certificate, as appropriate.
The create certificate self-signed webserver generates a self-signed certificate which is used for the local webserver. The SSR will, through a series of interactive prompts, request information from the administrator to generate either the request or certificate, as appropriate.
Forces re-generation of all automatically generated configuration items, and stages the configuration changes into the current candidate configuration. Configuration generation is done automatically as part of a commit. This command serves only to aid in debugging, and allows you to validate, inspect, and make edits, without committing the changes.
The create user command allows administrators to create user accounts for user and/or administrative access to the SSR's management port. Issuing the create user launches an interactive session that prompts for the new user's full name, password, whether they are an administrative or basic user, and the enabled/disabled state of that user account.
The delete command, when issued within the configuration hierarchy, lets administrators delete portions of the candidate configuration. This can be used to delete specific fields within a configuration element, or entire elements.
The delete certificate webserver command allows administrators to delete certificates that are stored on the SSR. Note that the SSR will always prompt the administrator to confirm deletion (the "force" keyword is not allowed).
The delete config command allows administrators to delete configurations from the SSR's filesystem that had previously been exported with the export config command. The force flag will skip the confirmation check without prompting the user.
The edit prompt command lets administrators change the display of the PCLI prompt, and includes a flexible array of options for customizability. In addition to various variables, the prompt string can include conditional statements, to affect the display of the prompt under different operating modes. All of this is accomplished by supplying a format string, which contains the syntax of the desired PCLI prompt.
The edit user command enters a configuration subtree specific to administering user accounts. From within this subtree, administrators can change any of the attributes associated with a user account (full name, password, role, and enabled state). This is done in a "configuration-like" way, where commands are issued as attribute value.
The export command takes a configuration from a previously created backup (via create config backup), from the candidate configuration, or from the SSR's running configuration, and stores it as a file on the local filesystem. It can then be taken off, moved onto other systems, archived, etc.
The export command's complement, import is used to reverse the process, taking a configuration archive and restoring it onto a system.The delete config exported command removes unneeded exported configurations.
This command allows administrators to load certificates into their SSR by pasting them into their active PCLI session. By issuing the import certificate command, the PCLI prompts the user for the name of the certificate they plan to import, then asks whether it is a CA (certificate authority) certificate or not. Once these questions are answered, administrators can paste the certificate, and is reminded to press CTRL-D once the pasting is complete. Pressing CTRL-D causes the SSR to validate the configuration to ensure it is a valid X.509 certificate before loading it into persistent storage. If the X.509 validation fails, the user is informed as follows:
This command takes a backup configuration (one that has been stored with the export command) and overwrites the current candidate configuration with its contents. Inclusion of the optional "force" keyword will skip the prompt for confirmation.
This issues ICMP requests to the specified destination-ip merely as a connectivity test, and bypasses the typical packet processing logic that would potentially restrict access to various tenants and destined for service addresses. The count modifier will affect the number of pings that are issued. The interface modifier lets administrators specify the egress interface for issuing the pings. The timeout modifier will set the waiting period for a reply before declaring the ping as a failure. The set-df-bit and record-route options enable the respective flags in the outgoing ICMP request.
The replace command is a powerful tool for making sweeping configuration changes, similar to a "find and replace" operation in a word processor.The replace command has several optional arguments that affect how the replacement occurs; case-sensitive will only match elements within the configuration that match the case supplied with the query string. The regex argument treats the query string as a regular expression. The whole-word argument requires that the match be an entire word, rather than just a substring or partial match.
This command removes all administrator-added configuration, and restores the basic configuration to all of the SSR's factory default settings. The PCLI will prompt for confirmation before resetting the configuration, unless the optional force modifier is added.
This command removes all administrator-added configuration since the last commit, effectively bringing the running configuration and the candidate configuration back to parity. The PCLI will prompt for confirmation before resetting the configuration, unless the optional force modifier is added.
The restore users factory-default command deletes all administratively created user accounts (i.e., all but the ones that are installed with the SSR routing software natively) and leaves the system with just the admin and user accounts.
This command is used to rotate log files (i.e., close the current log file and open a new one) generated by the various processes that comprise the SSR to rotate. The SSR's log files, stored in /var/log/128technology, keep 25 prior logs for each process, space permitting. Files are rotated such that, for instance, pcli.log becomes pcli.1.log while pcli.1.log becomes pcli.2.log, and so on. The oldest log file for each process is removed.
