to find out what version(s) you have installed on your vms server, you can add a dummy sensor.
do the following in ids mc:
devices>sensor>add, click next
(this info doesn't matter, as you will cancel, after you have the version info)
ip address: 1.1.1.1
sensor name: sensor
userid: cisco
password: cisco123
Next....
on the identification page, look at the latest signature available in the drop down. this is what has been applied.
you can just cancel this after you have the version.
you can find the above information in the link below:
