Sending email in Linux is pretty straight forward, once an email server is set up. Just use mutt or mail and all is good. But sometimes you actually want to test if SMTP is working correctly. And not only on your box, but on a remote box. That is of course easy using a MUA […]
After moving a server to a new machine with Ubuntu 16.10 I received some strange Postfix SMTP errors. Which turned out to be a connection issue to the MySQL server: postfix/cleanup: warning: connect to mysql server 127.0.0.1: Too many connections Oops, did I forgot to up max_connections during the migration: # grep max_connections /etc/mysql/mysql.conf.d/mysqld.cnf max_connections […]
I think I am a little bit late, but I finally took the plunge and am now the (hopefully) proud owner of a smartwatch. Not sure how smart this little gizmo is, but at least it looks neat. But first to the decision itself. It is not, that I don’t have a watch. Actually, I […]
Let me try something new. Just some nice pictures from our Labor Day weekend in Calabash, NC. Nothing special… just pictures.
It was that time of the year, when I had to renew some SSL certificates. Renewing and updating them in the server is a nice and easy process. But checking, whether the server is delivering the correct certificate and, that I updated and popluated the intermediate certificates correctly, is a different story. For websites it […]
While debugging my check disk problem after the 15.10 upgrade, I saw that I forgot to enable external commands.

Another day another foo, this time done to the check_disk plugin for Nagios on Ubuntu. After updating to 15.10 my disk space check all of a sudden failed with this one here: DISK CRITICAL – /sys/kernel/debug/tracing is not accessible: Permission denied It seemed a little odd, especially when I could access that file normally before. […]
Finally the Owncloud people got their updater to work for me, and I went ahead and updated. As a result I had to make some tweaks to CloudPress to keep my users active. Check it out and let me know if it works for you. Find my this new version here.
As a longtime OpenVPN user on Linux I thought it would be an easy task to set up OpenVPN as a service on Windows. Well, I was right… and couldn’t be wronger. Setting up the service is part of the installation notes for OpenVPN. Just search for “Running OpenVPN as a Windows Service” in the […]
It seems that Microsoft’s products creating more and more foos. This time it is Lync, also known as Skype for Business. It is okay, that Lync uses the Enter key to send a message or the CTRL-Enter combination start a call. But it is not okay that there is no way to change these key […]
