Problem

One annoying thing about the vSphere web client is the fact it throws you out after a period of inactivity. Now I know there are straight forward security reasons for this, and on a production environment thats fine. But on my test network theres just me, sighing every few minutes and logging back in again.

As the ‘Flash’ client is getting depreciated I’ll concentrate on the HTML5 client, but I’ll mention how to alter the flash client also. (If your version of VCSA still supports it!_

vSphere Disable Timeout

vCenter Appliance (VCSA) vSphere Disable Timeout

Connect directly to the console or via SSH. to launch a BASH type ‘shell‘, then execute the following commands

[box]

cd /etc/vmware/
ls

[/box]

 

You will see a folder for vsphere-ui (the HTML5 client) 

Note: For older versions of the VCSA, you will also see vsphere-client (the legacy Flash client).

Change directory to the client you want to alter the settings for, then edit the web client-properties file.

[box]

cd vsphere-ui
vi webclient.properties

[/box]

Locate the ‘session.timeout = 120′ value and change it to zero ‘0’ to disable, (or a new figure in minutes).

Note: Navigate with the arrow keys  > press ‘I’ to insert >  change the text  > press ‘Esc’ >  type ‘:wq’ to save and exit.

Then restart the HTML5 client with the following commands’

[box]

service-control --stop vsphere-ui
service-control --start vsphere-ui

[/box]

vCenter on Windows Web Client vSphere Disable Timeout

First you need to edit the config file for the web client > Windows Key + R > “%ALLUSERSPROFILE%\VMware\vSphere Web Client”

Locate the session.timeout value and change it to 0 (zero)  > Save and exit the file.

Finally restart the service. Windows Key +R > services.msc > Locate and restart the VMware vSphere Web Client service.
