In the last article, I had already announced that I would also like to use PRTG to monitor the web server protection of the Sophos UTM. Unfortunately, PRTG only offers generic sensors for the UTM, which makes monitoring a little more difficult. I've made some progress with the Sophos RESTful API, but unfortunately RESTful ...

In this article, I already presented a small script that checks the Exchange HealthCheck URLs. Since I use PRTG for monitoring in my private environment, I used a separate sensor for the HealthCheck URLs. PRTG comes with a whole range of sensors for Exchange Server, but due to the limitation of 100 ... Read more

Sophos has today released an update with the version number 9.502-4 for the Sophos UTM. The update is intended to fix a total of 39 problems. Unfortunately, Sophos has not been so lucky with updates for the UTM in the past, so the last update fixed some problems, but also caused new ones. Unfortunately, this makes extensive testing ...

After updating the controller, the script only returns the following error message: The request was canceled: No protected SSL/TLS channel could be created.... In this case it is the ... Read more
Let's Encrypt announced today that free wildcard certificates will also be issued from January 2018. Wildcard certificates (e.g. *.frankysweb.de) can be used to secure an entire domain via SSL with one certificate. With other certification authorities, wildcard certificates cost quite a bit of money, the cheapest wildcard certificate I know so far is just under 280 EUR for ... Read more

With the script you can quickly transfer all groups of a user to another user account: The GUI is only very rudimentary, you can select a source user account and a target user account, a click on "Copy groups from source to target ...

Let's assume that the users Frank and Hans are accessing a shared mailbox with the name Info: Hans and Frank have ... Read more
I received a lot of feedback on the first beta version of the Exchange Toolbox and was able to fix several problems as a result. Now there is a new version that mainly fixes problems, but also integrates message tracking. The goal of the Exchange Tool Box is to provide a small and handy GUI for quick troubleshooting.
