我正在使用 pulseaudio-dlna+pavucontrol 将我的笔记本电脑 (192.168.2.159) 的声音输出定向到我的 yamaha 立体声音响 (192.168.2.160) 这仅在我禁用 ufw 时有效sudo ufw disable

我很难找到正确的规则来允许特定的流量。

sudo tail -f /var/log/ufw.log

显示块消息，例如：

Apr 21 20:40:50 foo kernel: [ 5349.911161] [UFW BLOCK] IN=wlo1 OUT= MAC=01:00:5e:7f:ff:ff:ff:ff:ff:65:c3:04:08:00 SRC=192.168.2.160 DST=239.255.255.250 LEN=204 TOS=0x00 PREC=0x00 TTL=1 ID=0 DF PROTO=UDP SPT=40760 DPT=51200 LEN=184

如您所见，我已经添加了各种规则，但没有达到预期的效果，当我找到正确的配置时，我想再次删除：

sudo ufw status verbose

我用 iftop 注意到了这一点：

   # Host name (port/service if enabled)            last 2s   last 10s   last 40s cumulative
--------------------------------------------------------------------------------------------
   1 192.168.0.1:41144                        =>        61B        61B        61B     2.86KB
     239.255.255.250:1900                     <=         0B         0B         0B         0B

其中 192.168.0.1 是我的服务器。在我看来，我的服务器正在广播 UPnP 消息。这是什么进程？我怎样才能找到它？

语境

我的网络设置是这样的：
Internet ... [eth0] 我的服务器（充当路由器） [eth1] ... [eth0Asus] 华硕无线路由器 [eth1Asus] ... 无线局域网。
我正在测试使用iftop -i eth1.
