The expiring Let’s Encrypt DST Root CA X3 can cause problems on old servers:
root@server:/etc# wget https://www.example.com/monitoring --2021-09-30 21:34:39-- https://www.example.com/monitoring Resolving www.example.com (www.example.com)... 93.184.216.34 Connecting to www.example.com (www.example.com)|93.184.216.34|:443... connected. ERROR: The certificate of `www.example.com' is not trusted.
Fortunately there is an easy workaround to ensure the expired chain is not checked.
Due to a misconfiguration I had to shrink a LVM 2 volume group and its physical volume running on a software RAID.
Initially I thought adding a pair of Samsung 860 EVO as software RAID to my small home server cannot be too hard...
... but they seem to require special kernel settings to work.
The requirements of the Unifi Controller do not allow a direct installation. But with a few manual steps a successful setup is possible!
Setting up sympa with virtual hosts in an environment using exim requires some small modifications:
I use the squeeze-backport of redmine on Debian.
With the default setup, all the Ajax-Post-Requests cause the logout of the current user due to the missing X-CSRF-Token.
Because I could not find a complete solution, I backported the CSRF-Code from a newer relase.
Da die aktuellen Anleitungen für LXC mit Debian Squeeze etwas spärlich und teilweise veraltet sind, notiere ich hier einige Schritte für ein aktuelles Setup.
