Cisco IronPort ESA Finally Supports TLS 1.2

ASyncOS 9.5 is in Limited Deployment at the moment but you don’t have to wait long before it hits an ESA near you as Cisco seem to be pushing out ASyncOS releases pretty quickly these days.

9.5 comes with a bunch of new features including one many people have been waiting for – support for TLS 1.2.

See the release notes @ http://www.cisco.com/c/dam/en/us/td/docs/security/esa/esa9-5/ESA_9-5_Release_Notes.pdf

If you don’t want to wait for it to hit the General Deployment phase then you can raise a TAC support request with the serial number of your appliance and a request to be put on the LD list for release 9.5.

I’ll probably be doing this my self in the next few days. I also have a virtual appliance so can always snapshot the VM before the upgrade and roll back in case anything goes awry.

Downloading the Latest Malwarebytes Definitions File for Offline Use with PowerShell

Looking through my blog stats I saw that one of my old articles was still getting a lot of views – the one about downloading an offline copy of the Malwarebytes definitions file.

I decided to write a quick version 2 of the script so that it can now run natively in PowerShell without any third party tools (wget) – it’s also easier to understand and slightly more elegant only requiring four lines to do the job.

Troubleshooting a Broken Network Adapter in vSphere ESXi

You reboot a VM and 2 hours later you realise there’s no network connectivity on that VM.
You try to open the Network and Sharing Center console but the window just hangs and everything seems to be chugging along very slowly.

I’ve experienced a number of different scenarios where network adapters go AWOL in a VM – usually caused by a guest (Windows Update) or VM hardware update. For the latter it is best practice to update the VMware Tools first before upgrading the hardware version.

Backing up Media from Android to Synology NAS using BitTorrent Sync

BitTorrent Sync is an application based around the peer-to-peer protocol. You can use it to share files between friends and family or simply use it as an efficient way to transfer files within a LAN.

In this article I will briefly go over the steps I went through to Sync my camera photos and WhatsApp media folders from my Android smartphone to my Synology DS215j NAS.

The below guide should also help to get it working on an iOS device. I believe iOS also supports auto syncing just as the Android app does (i.e., you don’t need to have the app open for it to sync).
