通过SSH发出声音通知

12

我只是从Konversation IRC客户端切换到基于终端的IRSSI。我正在使用GNU屏幕+ SSH在远程计算机上启动IRSSI。我没有收到关于新邮件的声音通知，这意味着我必须不时签出IRSSI以获取新邮件。

这并不是真正有效的工作，所以我正在寻找一个应用程序/脚本，/usr/share/sounds/KDE-Im-Irc-Event.ogg如果有任何活动的话，它会在我的机器上播放声音（最好不要发出恼人的哔哔声）。如果我可以禁用某些频道的通知，那就太好了。

或者，如果不可能的话，通过进行某种通知libnotify，从而使其可用于GNOME和KDE。

我不喜欢libnotify，所以我用Python创建了UDP服务器，并为irssi创建了客户端应用程序。请注意，此答案适用于修订版1中的原始要求，没有文本通知。

客户

此版本会对针对您的各种消息做出反应。如果您希望收到任何频道消息的通知，请删除#该#'message public'行的开头。实施了一些速率限制，两次通知之间至少会有1.3秒的延迟。

服务器

启动时，它将侦听所有地址的端口3533。如果接收到UDP数据包“ M”，它将/usr/share/sounds/KDE-Im-Irc-Event.ogg使用paplay（“ PulseAudio play”）进行播放。收到时S，它退出服务器。由于它是开源的，因此您可以自由删除它。

#!/usr/bin/env python
# udpsoundserver.py

"""Listen on a UDP port and play a sound when 'M' is received

Starts the server listening on UDP port PORT (3533 by default) on address HOST
(by default all addresses). Valid commands are:
M - play Music
S - Stop the server

启动远程服务器的顺序变为：

screen -dm path/to/udpsoundserver.py
ssh -R 5355:localhost:5355

登录后，我运行：

screen -t irssi irssi

如果您以后需要重新连接：

screen -r irssi

启动之后irssi，您需要设置主机和端口：

/set notifyudp_ip_addr 127.0.0.1
/set notifyudp_port 5355

要使其在启动时自动连接：

/set notifyudp_auto_start 1

第一次，您需要手动启动“通知UDP”，因为它尚未自动启动：

/notifyudp start

为了测试通知：

/notifyudp ping

去做：

  • 使声音服务器在断开连接时停止
  • 允许跳过频道

我用libnotify做到这一点。我发现这个时代了。

它像冠军。我曾经在Linux上将它与libnotify一起使用（当我在linux机器上时仍会使用它），但是大多数时候我现在在Macbook上，所以我在Linux上使用growl代替libnotify。

要将其加载到中irssi，请运行以下命令：

/load perl

/script load fnotify

然后，我们需要将其路由到libnotify。为此，将以下内容另存为shell脚本并在登录时运行它：

# yes, we need a way to flush the file on disconnect; i don't know one
# yes, that's flush is not atomic (but good enough for me)
ssh remote.system.somewhere "tail -n 10 .irssi/fnotify ; : > .irssi/fnotify ; tail -f .irssi/fnotify " | sed -u 's/[<@&]//g' | while read heading message  do  notify-send -i gtk-dialog-info -t 300000 -- "${heading}" "${message}"; done # the sed -u 's/[<@&]//g' is needed as those characters might confuse  notify-send (FIXME: is that a bug or a feature?)
