How to start mplayer with radio (.pls) url over ssh and have it play?
by David C. Rankin 02 Jul '24

All, I know little about audio, but I'm trying to help my kids configure a radio stream. I normally use this media box via X desktop, but wanted to just play the stream via mplayer starting it over ssh -- that didn't work no matter what -ao I specify. However, if I open an x-term on the box from the desktop and enter the same url there - presto, the sound plays, and everything works. Since I normally use this box headless, how do I start mplayer over ssh and have the sound play on the remote box? Entering the following through the x-term from the desktop works just fine: mplayer -loop 0 -playlist http://playerservices.streamtheworld.com/pls/KDAQHD2.pls (it's classical) Is there a config somewhere where I can tell it to start mplayer the same from ssh as it does when started from the desktop? Following troubleshooting from the Sound Wiki, running 'pactl list sinks' over ssh while the desktop is playing the audio stream, I get: $ pactl list sinks Sink #1 State: RUNNING Name: alsa_output.pci-0000_00_1b.0.analog-stereo Description: Built-in Audio Analog Stereo Driver: module-alsa-card.c Sample Specification: s16le 2ch 44100Hz Channel Map: front-left,front-right Owner Module: 19 Mute: no Volume: front-left: 41944 / 64% / -11.63 dB, front-right: 41944 / 64% / -11.63 dB balance 0.00 Base Volume: 65536 / 100% / 0.00 dB Monitor Source: alsa_output.pci-0000_00_1b.0.analog-stereo.monitor Latency: 29816 usec, configured 31247 usec Flags: HARDWARE HW_MUTE_CTRL HW_VOLUME_CTRL DECIBEL_VOLUME LATENCY Properties: alsa.resolution_bits = "16" <snip> Can I use this information when starting mplayer over ssh to have it play sound through that boxes (the remotes) speakers? I've tried '-ao alsa' when starting over ssh, but still no sound. If I missed something in the wiki -- I missed it. Any help appreciated. -- David C. Rankin, J.D.,P.E.

openssh 9.8p1-1

The new openssh works just fine and this is just a little note to those of us with remote machines. After updating both client and remote machine(s) its important to restart sshd. If you don't restart sshd, and then attempt to ssh into the remote, it may fail with: kex_exchange_identification: read: Connection reset by peer -- Gene

JDK/JRE and older Java versions
by Peter Nabbefeld 01 Jul '24

Hello, as a Java developer, I sometimes need to do compatibility checking using older versions, often using JRE, while I need a JDK for development. When I tried to update arch linux now, I found I cannot start any update because the update is blocked by setting JRE and JDK as conflicting packages. I tried to only install JDK 21, but the update is still being blocked because of my older versions of the JRE. Why do You block any software installation? I don't like the idea to enforce me to use any specific software, or to remove any specific one. Is there any possibility to remove the lock-in? Kind regards, Peter
