How to open a port in Linux Mint?

Question

Computer networks

Good afternoon,
tell me, the torrent (transmission) does not work in Linux Mint, I
check here https://2ip.ru/check-port/?port writes - PORT IS CLOSED
$ netstat -ntpua | grep 51413
(Not all processes could be identified, non-owned process info
will not be shown, you would have to be root to see it all.)
tcp 0 0 0.0.0.0:51413 0.0.0.0:* LISTEN 2660/transmission- g
tcp6 0 0 :::51413 :::* LISTEN 2660/transmission-g
udp 0 0 0.0.0.0:51413 0.0.0.0:* 2660/transmission-g

Answer 1

How is the Internet connected? By default, ports on Linux are not blocked in any way.
iptables -I INPUT -p tcp --dport 51413 -m state --state NEW -j ACCEPT
iptables -I INPUT -p udp --dport 51413 -m state --state NEW -j ACCEPT
iptables -I INPUT -p tcp6 - -dport 51413 -m state --state NEW -j ACCEPT

Answer 2

as you pointed out, your styles file is in style/css/style.css,
and images in style/img/header_icon.png
in your case you are trying to find the image in the css folder, since the style/img/header_icon.png path is calculated relatively style.css file. those. you get this address for the icon style/css/style/img/header_icon.png
Therefore, change the address to ../img/header_icon.png and you will be happy

Answer 3

background-image: url(ваш_путь/изображение.png);
The path to the image is relative to the folder where the style is located. css
The path to the image is relative to the site root.

Answer 4

try
../style/img/header_icon.png
../../style/img/header_icon.png

Answer 5

Try replacing the code with:
Check if there is such an image.
Or are you uploading an image directly from Codepen?!
