Solaris10：用户音频

  • 772

我登录CDE（或Gnome）桌面之前的情况

mplayer Taste\ of\ freedom-A\ man\ sing\ his\ song.mp3 
MPlayer 1.1-4.8.2 (C) 2000-2012 MPlayer Team

我登录 CDE，然后远程登录 Solaris 机器（或本地），然后

我的问题是：谁可以更改权限？要修改哪个文件才能使这些权限永久生效，即使没有登录 cde 或 gnome？

我看到改变权限的设备是：

143130628      1 crw-------   1 myuser other    273,   0 Jan 15 00:14 /devices/pseudo/oss_sadasupport@0:sound,audio
143130630      1 crw-------   1 myuser other    273,   1 Jan 15 00:14 /devices/pseudo/oss_sadasupport@0:sound,audioctl

    实际上，作为一种解决方法，我使用一个旧的好脚本 SysV 样式 vim /etc/rc3.d/S80rclocal

    #!/opt/csw/bin/bash

case "$1" in
'start')
PATH=$PATH:/opt/csw/bin
export PATH

for file in /devices/pseudo/oss_sada*;do sudo gfind $file -not -type d -exec gchown -c mysuser {} \;; done
    ;;
'stop')
true
    ;;
*)
    echo "Usage: $0 { start | stop }"
    exit 1
    ;;
esac
exit 0
