When I try to install Channels on my Synology server running DSM 7.2.1 it errors stating port 8089 is in use.
I have a minimal setup: I am running Plex (32800), Roon (50000), and SABnzbd (8080), and Filebot ( 5452/5453)
I know the Synology push service uses port 8089, but I have that completely disabled.
Is there something I am missing?! I am not really a noob, but I sure feel like one now!
Thank you in advance for reading this! Hope someone has seen this before.
I don't have that issue with either of my Synology NAS's.
Here's their list of ports used What network ports are used by DSM services? - Synology Knowledge Center
Too see what ports are actually in use, you can connect via SSH (using something like putty) and issue these commands at the command line
sudo netstat -epat | grep 8089
sudo netstat -epat | grep LISTEN
The first command will list anything using port 8089
The second command will list all "LISTENING" ports
Haha... I am an idiot! (no surprise)
I went to ssh in, was denied, remembered I changed the port number, checked it in the control panel... You'll never guess to what I changed the SSH port number!
OMG...sooo dumb.
BTW, thanks for reminding me about netstat... sometimes I forget synology, with all it's bells and whistles, is still a linux os.
Appreciate the quick response. You saved me!
Wait, let me try to guess
