NetMRI 7.5.3 Released 31 Aug 2022
IntroductionAll existing customers have the option to upgrade their deployments to the auto-failover configuration for standalone, operations center, and collector appliances.
The following sections describe new features, supported devices, guidelines for upgrading devices, resolved issues, and known issues for the current release.
NOTE: Active penetration and vulnerability scans are conducted as part of the security testing. We have fixed all reported and discovered vulnerabilities related to SQL injections, and we have found and fixed a number of high-severity vulnerabilities. We will fix lower-severity vulnerabilities in the upcoming releases. To be exploited, all vulnerabilities require an authenticated user to initiate the action. Based on our knowledge and testing capabilities, we are unaware of exploits conducted by unauthenticated users.
New Features and ImprovementsThe following new features and improvements are included in this release of NetMRI:
Deprecated and Obsolete FeaturesThis section describes the features no longer supported in this release or planned for removal in future releases. These are the features that have not been adopted by customers or have been used only for specific cases in the past. NetMRI contains a rich set of features; to ensure that the focus remains on improving the features that are in use, we have trimmed many existing features and added new ones in areas where the number of use cases is growing.
Deprecated FeaturesDeprecated features are features skipped during release qualification. The code for them has not changed but might be removed in future releases.
In NetMRI 7.5.3, the CDS tool has been deprecated. As a replacement, please use NetMRI Advisor by Empowered.
Obsolete FeaturesBecause the SSH client has been upgraded, NetMRI 7.4.4 has dropped support for the following:
These versions were released in or before 2001 and predate the final SSH RFCs. The support for them is not necessary for RFC-compliant implementations of SSH.
If you get the “no matching cipher” error when attempting to connect to devices from NetMRI over SSH, use the configure ssh command to adjust the list of ciphers.
Planning for Deprecated and Obsolete FeaturesThis release does not contain features that are candidates for becoming deprecated or obsolete in future releases.
Guidelines for Performing UpgradesThe file with the upgrade image is ib_network_automation-7.5.3.XXXXX.gpg.
The following table provides guidelines and use cases for upgrading previous versions of NetMRI to 7.5.3.
A Note on External Authentication and Authorization ServicesIf you are using external authentication over SSL, ensure it supports TLS 1.2 before upgrading NetMRI.
Upgrading Sandbox InstancesBefore starting an upgrade, ensure that all local and remote sandboxes are fully and properly upgraded or reinstalled on the starting release version. If a sandbox is in an incorrect state prior to a follow-on upgrade, issues that are difficult to diagnose might arise.
Local sandbox instances for NetMRI are upgraded automatically.
Remote sandbox instances (for example, those on a VM server) must be manually reinstalled in the following cases:
To reinstall a remote sandbox instance:
To extend the size of an image and of an internal swap partition for the local sandbox, manually execute the sandbox reset command after the upgrade. Any changes made to the sandbox (for example, additional libraries installed) will be lost during this process.
Tested Versions of Web BrowsersNetMRI 7.5.3 has been tested with the following web browsers:
We have removed the “The browser you are using is not supported” warning. Occasional issues with display might occur because these browsers go through rapid release cycles. We expect that the coding of browsers is compatible with NetMRI and that highlighting the version difference in red during every login is no longer necessary.
