- Update to 21.3.7: - Changes for 21.3.7: * http://erlang.org/download/OTP-21.3.7.README * ssh: When an SSH server receives the very first message on a new TCP connection, and that message is not the expected one, the 64 first bytes of the received message are now dumped in the INFO REPORT that reports the Protocol Error. This facilitates the debugging of who sends the bad message or of detecting a possible port scanning OBS-URL: https://build.opensuse.org/request/show/699377 OBS-URL: https://build.opensuse.org/package/show/devel:languages:erlang:Factory/erlang?expand=0&rev=82
# 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 ```
