- Update to 21.3.1: - Changes for 21.3.1: * http://erlang.org/download/OTP-21.3.1.README * erl_interface: Fixed two bugs in the erl_call program. A missing initialization (introduced in erl_interface-3.11) which either caused a crash or failure to connect to or start a node, and an incorrectly calculated timeout which could cause failure to start an erlang node. These bugs only caused failures on some platforms. * ssl: The timeout for a passive receive was sometimes not cancelled and later caused a server crash. This bug has now been corrected. * ssl: Add tag for passive message (active N) in cb_info to retain transport transparency.

# Erlang in openSUSE ## Erlang Port-mapper Daemon and systemd Erlang Port-mapper Daemon in openSUSE uses systemd socket-activation. In order to fulfill security considerations, EPMd listens on loop-back interface by default. This is enough to run rabbitmq-server, ejabberd and user-started beam processes. For clustering, please, use ```/etc/systemd/system/epmd.socket.d/``` to configure interfaces to listen on. See man systemd.unit(5) for details. ### Upgrading from sysvinit ```/etc/sysconfig/erlang``` has no effect now, to configure EPMd use systemd capabilities instead. ### Example 1: change port Create ```/etc/systemd/system/epmd.socket.d/port.conf``` with following content: ``` [Socket] ListenStream= ListenStream=127.0.0.1:4444 ``` The first line is to discard vendor configuration. The second line will change the port number to listen on to 4444. ### Example 2: enable external interface To enable accepting external connections to EPMd, create ```/etc/systemd/system/epmd.socket.d/port.conf``` with following content: ``` [Socket] ListenStream= ListenStream=0.0.0.0:4369 ```
