Signature file (sig.pkcs7) : Specifies the acceptance level of the package.Descriptor file (descriptor.xml) : Contains metadata information about the package like dependencies, requirements, compatibility, whether or not maintenance mode or reboot is required….File Archive : Contains the actual files to be installed on the system (driver, patch or extension).Third-Party companies propose their own packages to extend the capabilities of vSphere in order to support their own solution or optimize the interactions between them.Ī VIB is made up of 3 different components: VSphere Installation Bundles don’t necessarily come from VMware. It is not to be confused with a Patch which is a collection of VIBs. Its purpose is to simplify the distribution and installation of drivers, patches and third-party extension modules. It is comparable to an RPM for Red-Hat systems or even an APK for Android. VIB is a term that comes up quite a lot in the VMware world, but what is it exactly?Ī “ vSphere Installation Bundle ” is a package, or archive, that contains the necessary files to install the payload on a vSphere host. We will also demonstrate how to install and update packages, where to find them, how to know which one to use… vSphere Installation Bundle ![]() In this blog, we will describe what these packages look like for vSphere hosts and how to interact with them. ![]() Running hosts with outdated or unsupported Firmware and Driver combinations can lead to incredibly unstable systems which in turn will cause all sorts of headaches like PSOD, IO devices disconnecting randomly, you name it… Ensuring supported and up to date packages is actually the first step VMware support engineers take when responding to a Support Request (SR). Enforcing a supported configuration and up to date infrastructure comes with the task of managing drivers, patches and software extensions on the hosts. They need to ensure that they are working according to the baselines and provide the best possible SLA. The same principle applies to local troubleshooting with ESXi Shell.A great number of responsibilities belong to vSphere administrators in a datacenter team as the hosts are one of the foundation stones for all the other systems. So, it will close your interactive SSH session but SSH service will stay up and running so you can reconnect and continue with troubleshooting. In other words, if you do a troubleshooting via SSH session (SSH service must be running) this setting will close the active SSH session in case of idle (no interaction) is higher then UserVars.ESXiShellInteractiveTimeOut value. ![]() Advanced settings parameter UserVars.ESXiShellInteractiveTimeOut configures timeout from the active (interactive) session. If you have started ESXi services ESXi Shell or SSH Service you can do local or remote troubleshooting. What does UserVars.ESXiShellInteractiveTimeOut setting? I think the reasonable time for troubleshooting is for example 4 hours which is 14400 seconds. That's the reason for best practice to set this timeout setting to some reasonable time for troubleshooting and to stop services automatically after configure time. There is a potential risk that vSphere admin will forget to stop these services after troubleshooting and it would have a negative impact on security as these services should be running only for troubleshooting. The default value of UserVars.ESXiShellTimeOut is 0, therefore these services will stay up and running until vSphere admin stop them manually. We are talking about ESXi services highlighted in the figure below.Īdvanced setting parameter UserVars.ESXiShellTimeOut is the time in seconds how long are these services (ESXi Shell and SSH) running when explicitly started by vSphere admin for troubleshooting. ![]() If you want to troubleshoot ESXi locally or remotely, you have to enable services ESXi Shell or SSH. What does UserVars.ESXiShellTimeOut setting? ESXi Shell (Local Troubleshooting Shell available in Local Console).Is it clear? No? So, here is a more human-readable explanation. Takes effect only for newly logged in sessions. Key: UserVars.ESXiShellInteractiveTimeOutĭescription: Idle time before an interactive shell is automatically logged out (in seconds, 0 disables). Takes effect after the services are restarted. Let's start with description of both parameters available in ESXi hosts.ĭescription: Time before automatically disabling local and remote shell access (in seconds, 0 disables). What is the difference between ESXiShellTimeOut and ESXiShellInteractiveTimeOut? However, it is good practice to set these timeouts as it has a positive impact on security. ESXi Advanced Settings have two timeout parameters to manage ESXi Shell timeout:īoth parameters are by default set to 0 which means the time-outs are disabled.
