Devuan / Debian Versions

Admins who prefer a Unix style operation systems and don’t like the centralized “one tool doing it all” approach of systemd, switch to Devuan. This mostly improves uptime over boot time. Admins of servers don’t care about boot time and prefer uptime.

This list keeps track of the related versions of Devuan and Debian.

DELL iDRAC6 with Java8

Problem: The remote console feature of a Dell R710 server does not open with an Linux client with errors like these:

Connection failed, Unsigned Java Applett, etc

Solution: I had to change three things:
in /usr/lib/jvm/java-8-openjdk-amd64/jre/lib/security/java.security I had to change to these lines:

# from
# jdk.jar.disabledAlgorithms=MD2, MD5, RSA keySize < 1024, DSA keySize < 1024
# to
jdk.jar.disabledAlgorithms=MD2, RSA keySize < 1024, DSA keySize < 1024

# from
#jdk.tls.disabledAlgorithms=SSLv3, RC4, DES, MD5withRSA, DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL
# to
jdk.tls.disabledAlgorithms=RC4, DES, MD5withRSA, DH keySize < 1024, EC keySize < 224, 3DES_EDE_CBC, anon, NULL

And in ~/.java/deployment/deployment.properties I changed these lines:

# from
#deployment.security.level=MEDIUM
# to
deployment.security.level=ALLOW_UNSIGNED

And there is still a small bug: cursor keys won’t work, but numpad cursor keys do.

Hello world

My daily job is solving IT problems. No matter if they are hardware/software, or os/configuration/application related. There is always a bug to be fixed.

This blog will be the place to remember some solutions to problems, because as time goes by it’s sometimes hard to remember how I debugged. Some solutions will be public, if I think others could be interested.
