add tcp6 and tcp ports

Hello, your panel has enabled monitoring ipv6
What does it mean when you can't access? It is recommended that you check whether the system firewall and the security group of the server provider are open to the port used by the panel
Check if the full link is used to access the panel, execute the command to view the full link: bt 14

Hello.
Please see the link i has been inserted in last post.
I want define for TCP/IPV4 therefor panel be accessible by my server IP.
Thanks
only TCP6 has been defined.

aaPanel_Kern

arsse
Hi, define the port? If yes, you can modify it directly on the panel, and the server provider needs to open the relevant ports

arsse

aaPanel_Kern

netsatat -nlput
Show only a line for tcp6:
tcp6 0 0 0:::2222 :::* LISTEN 4528/python

but i think ,it need this record for tcp therefor i can load my control panel:
tcp 0 0 0.0.0.0:2222 0.0.0.0:* LISTEN 4528/python

Hi, 1. It is normal to ignore it. 2. The panel closes the monitoring of ipv6
The panel only monitors ipv4 by default, and both ipv4 and ipv6 will monitor after ipv6 monitoring is enabled
Can't access what information? Do you want to use the full link to access the panel?

arsse

aaPanel_Kern

Thanks for response me.
I have only tcp6 i need tcp line but i do not know how i can with command line?

aaPanel_Kern

arsse
Hello, the above is more clear, this is normal, turn off ipv6 monitoring

arsse

aaPanel_Kern

Hello
My question was very simple. why you do not answer?
I said i have directive of tcp6 but i need directive of tcp!
how i can use linux centos 7 or 8 commond line for create it. please help soon.
I do not access to panel

Hi, can you give us your aapanel information? The server makes a snapshot backup first, if possible, please send it to kern@aapanel.com.
It is recommended to fill in the following
Post link:
SSH IP address, account password and port:
aapanel login link address and account password:

No post link will not be able to know which user's information is, and the problem will not be processed

arsse

i add this:
nono /etc/services
python 2222/tcp

but when netstat -nlput
it do not show tcp line with 0.0.0.0 service ip address

arsse

there is no access to panel

arsse

aaPanel_Kern

previous post edited and i add new info.

Also if possible i not send user/pass, rather, you write guideline until solving problem.

aaPanel_Kern

The server executes the command to check whether it can be connected?
curl http://127.0.0.1 2222
Is it possible to connect using a third-party scanning website? If not, please check whether the firewall of the server system and the security group of the server provider have opened relevant ports
The information you gave shows that the ipv6+ipv4 port is monitored, but the ipv4 port is not displayed
https://dnschecker.org/port-scanner.php

arsse

aaPanel_Kern

port checked and saw is open.
firewall is off.

((The information you gave shows that the ipv6+ipv4 port is monitored, but the ipv4 port is not displayed))
it must show 2 line for 2222 python but only tcp6 and has not tcp

Execute the command check and take a screenshot of the complete result
curl -O -m 3 https://download.bt.cn/tools/bt_check.sh && bash bt_check.sh

its a universal problem is made by some type of software or kernel modules that is installed by this panel
my services were on system but after installing this panel on centos 8 stream
services instead tcp will listen on tcp6 socket

you can reproduce this problem
get hourly vps in aeza.net install centos 8 stream on it
run some services with open port
now install aapanel
restart your services see what happens to them

SOLVED: problem is related to kernel that tcp6 socket should handle both ipv4 and ipv6 connection
that centos 8 stream with kernel 4 will fail on it by some update or installation of some app by aapanel. so i installed debian 11 with kernel 5.10 and thats ok so that tcp6 will handle both ipv6 and ipv4 connections
