RocketChat service listening on two ports (3000 and a random one)

athoik commented 1 year ago

Description:

Hi,

I am having the latest version of rocketchat 6.4, and after inspecting the system ports, I noticed that rocketchat is listening on two ports.

The service already has PORT=3000 and BIND_IP=127.0.0.1 but that doesn't seem to affect the second port.

root@rocket-chat:~# ps aux | grep Rocket.Chat | grep node
rocketc+     741  0.8 29.7 1862520 580356 ?      Ssl  15:21   0:35 /usr/local/bin/node /opt/Rocket.Chat/main.js
root@rocket-chat:~# ss -tunpl | egrep "node|Netid"
Netid State  Recv-Q Send-Q Local Address:Port  Peer Address:PortProcess
tcp   LISTEN 0      511        127.0.0.1:3000       0.0.0.0:*    users:(("node",pid=741,fd=40))
tcp   LISTEN 0      511                *:41305            *:*    users:(("node",pid=741,fd=31))

root@rocket-chat:~# systemctl restart rocketchat.service

root@rocket-chat:~# ps aux | grep Rocket.Chat | grep node
rocketc+    1059 86.7 30.6 1598728 596256 ?      Dsl  16:33   0:13 /usr/local/bin/node /opt/Rocket.Chat/main.js
root@rocket-chat:~# ss -tunpl | egrep "node|Netid"
Netid State  Recv-Q Send-Q Local Address:Port  Peer Address:PortProcess
tcp   LISTEN 0      511        127.0.0.1:3000       0.0.0.0:*    users:(("node",pid=1059,fd=41))
tcp   LISTEN 0      511                *:45311            *:*    users:(("node",pid=1059,fd=34))

As you can notice above as expected, the RocketChat honors BIND_IP and PORT, but the second random port, ignores them.

Connecting to that port (eg via telnet or using curl http://localhost:random-port) show the following error in logs:

From above log I guess is related with moleculer.

Searching on RocketChat didn't notice any instructions how to disable that port or make it listening on loopback only etc.

This blog mentions that you are already working with moleculer but no further instructions.

How can we change that port to listen only on loopback? Or how we can disable it?

Thanks a lot.

I want to work on this issue,please assign me to this ?

houjuan0623 commented 1 year ago

As you mentioned above，"Manual Installation" means do you download the production version of the package or package it yourself?

I konw meteor will start a proxy port. 3000 is the proxy port, random port is the listening port that provides the real service.

athoik commented 1 year ago

By manual installation I mean the procedure documented here: https://docs.rocket.chat/deploy/deploy-rocket.chat/additional-deployment-methods/deploy-on-debian

Process id that runs RocketChat, starts a random port (33085 as seen below), listening on all interfaces.

root@rocket-chat:~# ss -tunpl | egrep "node|Netid"
Netid State  Recv-Q Send-Q Local Address:Port  Peer Address:PortProcess

Connecting to that port shows the moleculer error bellow.

The same problem with Rocket.Chat Version: 6.4.5
