Switching…

Just found my Software update icon jumping again in the dock of the server when I used VNC to remotely login. It looked like another security update has arrived. Mostly minor issues as you can see here. The most important ones where the fix to OpenSSH and telnet which I frequently use myself. Another security hole bites the dust. I’ve got my server updated, when do you update yours.

I know I’m a bit late with this but for everyone who used my info to configure their mailserver needs to know this even if it is late. I don’t have a record who is using my setup and therefore I have no others means than posting this and hoping you will read this. I found out the hard way by trying to email someone who uses my setup and to find out my mails are rejected. I got emails returned with the error message:
