Port 7878

[Madox Valdivia]

ifyou really wanted to change it inside the container without external tools then set your docker config back to 7878:7878 open the sonarr web gui (on 7878) and change it in there to 8989, then also change the docker config back to 8989:8989 and recreate the container.

you need to remember that just because you exposed/mapped an internal port that doesnt mean theres anything actually listening on that internal port. you have to make sure the application is configured to use that port as well.

Notes:

Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services.

Well Known Ports: 0 through 1023.

Registered Ports: 1024 through 49151.

Dynamic/Private : 49152 through 65535.

TCP ports use the Transmission Control Protocol, the most commonly used protocol on the Internet and any TCP/IP network. TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent. Guaranteed communication/delivery is the key difference between TCP and UDP.

UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol) and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery. UDP is often used with time-sensitive applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.

When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. This can be accomplished in both Windows command prompt and Linux variants using the "netstat -aon" command. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software. For more detailed and personalized help please use our forums.

Is it possible to find specific port using command prompt? I want to use the exec command in php to check if a port is open. The fsockopen function in php is very slow so i wanna try to use the cmd to check the port and see if that works better. I want to find if port 7878 is open.

Successfully running radarr as reverse proxy traefik with docker. Just created an additional radarr instance (radarr-uhd), which is accessible via localhost:port but the reverse proxy is giving a 502 for the new instance.

Here's what I did:Enabled SOAP & RaDownloaded PuTTy.exe as a Telnet source.Port forwarded 7878Port Forwarded 3443Tried Telnetting to 7878, DOES NOT CONNECT - attempts but closes immediately when it tries to.Tried Telnetting to 3443 CONNECTS no issues.Setting up Azer-Cms OR MangosWeb, using Ra does NOT connect to the server and fails delivery on web shop items.Setting up Both on SOAP and it still does not connect.Soap is ALSO enabled on Webhost.SOAP is binding on 0.0.0.0RA is binding on 0.0.0.0

I have tried 0.0.0.0 and 127.0.0.1 and nothing has worked. I have NOT tried 192.168.1.XXX to connect and I'll try that next.

I have also enabled the ports so I don't know possibly what else I can do to enable both internally or externally to connect to SOAP

I can SSH to both of the servers. How can I allow the tomcat server behind the firewall to be able to send data to the MySQL with port forwarding/ssh tunnel? I've read about the conecepts but I just can't seem to grasp my head around it, hence me asking for practical help and explanation.

Once you have the basic ssh config set up it should be relatively trivial to create a script to start the connection (including a forwarded port) which could for example be executed when your network interface comes up, similar to the way a lot of people have their iptables rules loaded.Take a look in /etc/network/if-up.d/ (off the top of my head) for examples.

everything fine but I cannot access the webpage when running the docker.

curl on localhost 7878 gives me

curl: (52) Empty reply from server

the same when querying from another client on the same lan

I changed the default port on, in this case, the docker template for binhex-radarr: since this is a second iteration of this docker (notice it's listed as binhex-radarr2160), I changed the default port from 7878 to 7979. However, on the Docker Container screen, under the "Port Mappings (App to Host)" column, it still displays :7878/TCP :7878 instead of appropriately to 7979. I suspect this is my problem. How to I change these settings appropriate? It's worth mentioning that the first iteration I have of this docker works fine. These both being routed through another docker, that's why the network column appears as such. Also, the container (new one labeled 2160) appears to be running just fine, and pulling correct VPN IP throu gh the other container displayed via "curl ifconfig.io"

I am also having this issue, and if I add a new port mapping it doesn't show up. It's like Docker is no longer applying my port changes. FYI, I am on the custom bridge: Proxynet, as I followed SpaceInvaderOne's tutorial.

I'm considering moving my dockers to their own IPs across the board rather than all bridged to the UnRaid IP and ports. It should be as simple as moving each to br0 then manually specifying an IP that is not taken anywhere else in my lan. This works for Plex which I have moved. For those dockers that like inter-docker chatter like Sonarr, I cannot get it to see any of its targets like qBittorrent, Jackett, etc., even if they are on the same br0 and their own IPs (and Sonarr correctly set to point to the new dedicated IPs).

Do I need to make another custom bridge (br1) in my subnet and have all the dockers ride that? Docker settings show the subnet as 192.168.0.0/16 and my correct gateway for my lan (192.168.1.1 on my 192.168.1.x). Ensure the routing table reflects br1 on the 192.168.1.x?

If you want to restrict access with nginx you should remove the external port mapping ([[services.ports]]) in your fly.toml since your service is currently exposed.to the internet on ports 80 and 443. I have also had issues in the past using .internal addresses while having external ports mapped.

Since platform requirements may change with new releases of a product, please consult the Platform Support for Universal Controller 7.2.x and Universal Agent 7.2.x page to make sure that your platform is supported before performing an installation.

The Agent log rolls over at midnight (12:00 a.m.) or whenever the Agent is restarted. The Log File Retention Period in Days Universal Controller system property lets you specify the number of days that an Agent log file (in addition to a Controller log file) is retained before it is purged. The default is 5 days.

Universal Agent components run on z/OS, Windows, UNIX, and IBM i operating systems. These systems must be connected with a network that supports TCP/IP. For example, the Universal Command Manager running on a z/OS system must be able to establish a TCP/IP socket connection with the Universal Command Server running on a UNIX or Windows system.

TCP/IP provides a set of commands to verify network connectivity between systems. For example, the ping command can determine if an IP connection is possible between two systems. However, the ping command may not work in all network environments. In addition, the ping command may work, but a firewall may deny all other connection attempts between the two systems. Check with your local network administrator to determine the capabilities and topology of your network.

Universal Agent offers configuration parameters that can facilitate connections through network firewalls. Due to the large variety of firewall configurations, all possibilities cannot be discussed in this document. Check with your local network administrator to determine if a firewall is between the computer systems involved.

Universal Agent is composed of several components that utilize the TCP/IP network for component communications. TCP/IP routes must be available between the distributed components and firewall rules open, if necessary. The primary components using TCP/IP are Universal Broker, Universal Managers, and Universal Automation Center Agent (UAG).

Hey guys. I want my NAS to be reachable from outside my network. Actually, I just want to be able to use the nzb360 app with radar/sonarr/bazarr outside my local network. I've installed duckdns via docker, also Nginx proxy manager. I have an Duckdns account, and I have created a new domain there. When I start the Nginx proxy manager I go to add new proxy hosts. When I click the Save button I get an error "Internal error". This is if I select to create a new SSL certificate. I have ports 443 and 8888 forwarded. If I go to that duckdns domain and add for example 7878 port for radarr, the page opens, so that's good. I just need to add SSL to it. I founds some logs and they are something like this:

Go to /home/YourMasterUser/.config/Radarr/config.xml find the make sure it looks like this radarr if it doesnt make the changes and then you need to restart the service with this command systemctl start radarr.service that should fix you up.

This is the best method as Radarr should be able to have access over https with our proxy config, no need to manually enter ports. As @AJP69 has stated, you need to only make sure your URL base is correct.

The above command will create a local server on foo listening on port 7878 and any TCP traffic to this port will be transparently tunnelled to bar:7878 over ssh. The tunnelled traffic will be encrypted as well which should be enough to bypass most firewalls.
