How do you open ports in Ubuntu so that you can host a server on linux?

I nmapped my ip and 3306 is closed, 80 is open, thats it though.

How do you open ports in Ubuntu so that you can host a server on linux?

I nmapped my ip and 3306 is closed, 80 is open, thats it though.

The command was:
sudo iptables -A INPUT -p tcp --dport (port number) -j ACCEPT

I tried that and it did not work

I tried that and it did not work

Well, first check the ports that are open with the following command: netstat –lp --inet
Disable firewall, see if that's the problem with the command: ufw disable, hope i helped even a little

steven@steven-desktop:~$ sudo ufw status

And I still get connection refused to my server even though all ports are port forwarded as well....

well even with ufw disabled i still get connection refused 10061 on my other computer so that doesnt make sense what could it be????

 

[mokle94]

Well, do you get an error when you host your server, what version are you hosting, maybe some more info?

It seems like port 3306 is only opened on IPv6, you will also have to open it on IPv4. I don't really know how since i never had this problem before.
But maybe it helps a little. good luck

I'm hosting .4 TFS 8.60 I don't get any errors when I host it but when I try to log on to it from the ip redirect I get "cannot resolve host" and when I try to log on from 127.0.0.1 it goes to the account manager (on my own computer, not my other computer) and then it just sits there connecting forever....

so what's the problem??

oh and I don't even see him log in but I get this error in my console

[19:21:23.776] Account Manager has logged in.

[19:21:23.777] [Error - CreatureScript Interface]

I don't want to be a smarta** because i didn't have that error myself but it seems the problems is in login.lua
Why don't you try this script : login.lua
Atleast try in localhost.

 

[ziggy46802]

well I took care of that problem and it just stayed connecting forever, so I tried with your login.lua and it still goes to account manager but then connects forever with nothing coming up in the server window

- - - Updated - - -

PORT     STATE SERVICE
22/tcp   open  ssh
80/tcp   open  http
631/tcp  open  ipp
3306/tcp open  mysql

this is my nmap of my localhost, my ip redirect is only 80 open (why???)
how do I get 7171 open, I've tried everything and nothing seems to open it.

when I do sudo ufw allow 7171 it just does this

steven@steven-desktop:~$ sudo ufw allow 7171
Skipping adding existing rule
Skipping adding existing rule (v6)
steven@steven-desktop:~$

how do I make it so it does it for all?

 

[mokle94]

I'm really out of ideas, try to restart apache, you're using it right? Maybe someone with more experience will help you later.
I really hope that you'll fix that problem, cheers

 

[ziggy46802]

Apache? Actually I don't think I am using it, but I did try restarting my computer to no avail.

Router? if so, make sure it is open there and that is pointed to your router IP(192.168.1.XXX) .

I dont get what you mean, how do I open my router on my host and point my host to 192.168.1.103 which is my address on the router?

On your browser type: 192.168.1.1
this will send you to your router's admin panel login screen.
Typically the username is "admin" and the password is "password"(assuming you did not put your own password) it all depends on brand, google your brand for more info, look under your router or refer to you user manual.

After login in, find anything in relation to Ports or "Tools".

Follow instruction on how to Port Forward.(most routers describe how.)
