Can't access :8088 and :7080

[bluedogranch]

I've got a strange issue on Ubuntu 20.04.1 LTS at Linode. I successfully installed OpenLiteSpeed, and

sudo /usr/local/lsws/bin/lswsctrl status

shows litespeed is running with PID xxxxxx.

PHP7.4 and MariaDB were already installed.

But I am getting timeouts at example.com:8088 and example.com:7080.

ufw status shows:

65500                ALLOW        Anywhere                 
443                    ALLOW        Anywhere                 
443/tcp                ALLOW        Anywhere                 
7080/tcp            ALLOW        Anywhere                 
8088/tcp            ALLOW        Anywhere                 
OpenSSH        ALLOW        Anywhere                 
80/tcp                ALLOW        Anywhere                 
65500 (v6)        ALLOW        Anywhere (v6)            
443 (v6)            ALLOW        Anywhere (v6)            
443/tcp (v6)        ALLOW        Anywhere (v6)            
7080/tcp (v6)    ALLOW        Anywhere (v6)            
8088/tcp (v6)    ALLOW        Anywhere (v6)            
OpenSSH (v6)    ALLOW        Anywhere (v6)            
80/tcp (v6)        ALLOW        Anywhere (v6)

I'm using 65500 as the SSH port for security.

netstat -an | grep 7080 shows:

tcp        0        0 0.0.0.0:7080        0.0.0.0:*        LISTEN    
udp        0      0 0.0.0.0:7080            0.0.0.0:*                         
udp        0      0 0.0.0.0:7080            0.0.0.0:*                         
unix  3      [ ]         DGRAM                    17080

netstat -an | grep 8088 shows:

tcp        0      0 0.0.0.0:8088            0.0.0.0:*               LISTEN

But I can't connect at example.com:8088 and example.com:7080.

I've read that I need to open the localhost port in ufw; is that true?

Is using 65500 as the SSH port for security a problem? Does it conflict with OpenSSH?

Do I need to stop Apache now? Or only when I change OpenLiteSpeed to port 80 and 443?

Thanks!

Hi,

If you can curl from localhost, then you probably have the firewall issue on the network layer.

Best,
Eric

Thanks! That's interesting. Running
curl 127.0.0.1
gives me the text of the index.html file at root, and
curl http://localhost:8088
gives me the html dump of the OpenLiteSpeed admin page.

So it must be the ufw firewall somehow? Or IPTables?

Update: disabling ufw doesn't help. I still can't connect to example.com:8088 and example.com:7080.

Does Linode have its own firewall? I know my VPS provider does. Look around in Linode.
