I made a gift for Starcraft community - port tester for Starcraft. Here is it.
Why open port?
- If you want to create games.
- If there are more than 2 persons in game. There can be a maximum of 1 player with the closed port in a game, otherwise terrible lags will begin, besides that it will be heavy to define, because of whom it is lagging. The probability of this should be better reduced to a minimum.
Instructions:
1. Start Starcraft. Connect to any server. Login is not necessary.
2. Visit this page.
3. Enter port.
4. Press "send"
5. ???
6. Profit!
How to open port:

This tool is in a beta, besides that, I am a noob in php and html  I'm waiting for responses.
Official page (english): here.
Official page (russian): link.
Edit 19.08.2013: updated the link.

Hows that possible that my 6112 port is closed, I'm playing on B.net fine without any laggs, 3v3 4v4 all fine
|
Can you create games?
Did you forwarded another port for Starcraft?
|
dying starcraft community?

No, I never forward my port (and I dont have to) because my network is extranet.
|
So you just had luck. Or you had lags but then forgot it.
What is extranet?

maybe I used wrong word, AFAIK if my IP is not 10.0.0.0~10.255.255.255, so I dont need to do anything with the port.

You mean you have external ip?
So can you create games?
|
it is not a dying community at all.

I edited out the dying to avoid derailment, hope you don't mind.

I had simmilar thing here, every time i check any port through some port-testing site (including this) it tell's me i have ports blocked or closed (even when i turn off FW's, AV's and even my routers FW's and other security features and turn on DMZ) but everything is usually working fine (including BW) go figure :/
anyways thanks for sharing such feature, hope someone will find it usefull ;]

@Nao: again, if you can't create games, you just have luck, that you play games with more that 2 players and it don't lag because someone else has his port closed.
@IntoTheWow: If it's not dying, what's the better synonyme? I noticed after SC2 came out that there are ~1k instead of 2,5k online on iccup, and significantly less on other servers.

xpeh that's a debate for another thread or blog, i just removed it cause people will focus on it and this thread will turn into "Is BW dying?" rather than a thread about the port tester pool.

Ok, whatever. But it's a pity nobody made it before, as starcraft was more popular.

The ability to ping is quite useful.
Thanks!

Hmm with my previous post i meant that BW and all else is working fine even with closed ports indication from your and other test sites.
It even worked in 2v2 with two players on one modem (separate ports had to be forwarded for each comp thou).
I'm just wondering why it is like that, because if something is not working propery i can't tell if it's the port's fault or what (thou in most cases it isn't).
And about BW lags, i suspect that besides ports there is another factor for it, like some obsolete protocol or network function that BW want's to use and some ISP / networks have abandoned or blocked it.
I remember for BW (and hamachi too) i had random people with connection problems but only with certain pairing (ie: i had a friend wich i coudn't play with but me and him could play other (same) people and we both could make games and play with more than 2 players in mach).

This has definitely nothing to do with ISPs.

1. Starcraft connection: http://translate.google.com/translate?hl=en&sl=ru&u=http://harpywar.com/?a=articles&b=1&d=27&langpair=ru|en&hl=en&ie=UTF8
1. The game goes P2P between players. Connection type is a star - any player is connected with all other players. Failed connection between any 2 players leads to very hard lags where you have like 2 FPS. The server acts only as chat server / game statistics keeper / game list keeper, that's why /p command on pvpgn (which also iccup is) outputs shit and shouldn't be used for searching for lagger.
Game delay is equal for every player in a game, regardless of their internet latency time, and is equal to biggest ping between players in a game. That's why Starcraft awfully sux!
2. Closed port means you can't accept incoming connections. If 2 hosts cannot accept connection - they cannot establish a connection between them, since one must initiate a connection - and other must accept.
1+2 => There can't be more that 1 player with closed port in a game without lag.
What you are meaning as "certain pairing" and other as "player incompability" means that there is no connection between these 2 players, mainly because they both have their game ports closed.
|
That was quite informative, thank you!
I have a question thou, as my test brings up 6112 as closed port.
When I'm in game i can see (trough a program called Netlimiter) that BW sends and recives data on 6112 port, does it mean this port is actually open ?
(I have no problem playing 1v1 on ICCUP, only try to understand networking better)
|
Under open port here is actually meant that port can accept incoming connections.
If the connection is initiated from inside, after that you can receive packets. This is like telephone call, where you have no own number - but after you have called someone, you both can talk with each other in both directions.
|
Hmm i understand...
Since i already tried the standard methods of opening ports (i even tried setting up DMZ on my router), i will look into it more and if i find something usefull maybe i will post it here.
Anyways thanks for help ;]

It says my port is closed as well even tho I host full games all the time with no lag. I am on DMZ.
However, I do find, when I'm on my router, that I can't join as many games and I have not been able to figure out why. More games appear as "latency to high to creator" as soon as I get off my Router I do not get that problem anymore. I have tried changing various settings with no success.
|
If you have the game connected to a server and the page shows that your port is closed - maybe you use another port? Go to iccup, type /netinfo and look on "Game UDP" entry.
What do you mean with "on/off my Router"? DMZ on/off?
|
Game UDP is "none"
However, this time when I ran the test it showed "open" so looks like there is no problem there
-----------
To side track the topic then;
Why is it that when i'm on my router I cannot join more than half the games due to latency but I can host 4v4 no problem and still join some games with no problem?
Then when I'm off the router, I can do everything perfectly fine and can join all games?

Sorry, "Client UDP".
Read my answer before repeating the question.

Port forwarding has nothing to do with joining games, as outgoing connection is made. So it can be a fault of something else, e.g. your router, firewall, etc. Or you have just luck - laggers disappear as far as you "go off router" (whatever it means).

For all you guys wanting to portforward. first check if you have a modem/router and a router or a modem and router. The first set up is relatively hard to portforward

On/Off Router = Using router or not using router.
DMZ = When on router, you set yourself to bypass all router settings. Therefore port forwarding is not necessary; however I do it anyway.
I do not use firewall
I is not luck
I have friends I cannot join when using router, those same friends I can join when not using router.
|
Ah, you mean you have external IP on your PC when not using router? So this can be a fault of your router, i can't tell you more. What router do you have?
|
I think this thread is awesome because some times opening ports are such a hard puzzle to solve.
And the OP is willing to help out or at least figure out some situations, which is awesome!
Thanks OP!

It is definitely the fault of my router but I cannot figure out the setting causing it. I can turn off all settings, place myself on DMZ and it will not change a thing. Maybe it is possible that my router simply increases my latency?

Well, it didn't work correctly sometimes anyway, or something is messing up stuff (antivirus/firewall/etc.)
I checked it there a bunch of times with ports open and it didn't show them open sometimes. Maybe it's just my comp/connection/router.
There are plenty of pages that do the same thing, just google it.
Here's one:
http://www.yougetsignal.com/tools/open-ports/ (not sure if it checks TCP or UDP or both...)
(Note: it shows my ports as closed, but they're open; don't know why is that)
EDIT: Ah, found an explanation on this, I thought it was something like this, but I'm not savvy in the matter to know for sure:

Thank you for reply. For me that link always worked correctly.
Your link seems to check only TCP ports or the site is buggy. (it also always says that my port is closed) + Show Spoiler +About the explanation. It just describes some difference between TCP and UDP protocols, and says that their port scanner is able to check UDP ports state. However the first post contains a good link http://nmap-online.com/ that works as a web interface to a great nmap scanning tool.
The only website I found that really checks UDP ports is http://nmap.online-domain-tools.com
In order to use it you need to select "Custom Scan" and replace all options with "-p6112 -sU -T5 -Pn". The patterns looks like this:-p6112 -sU -T5 -Pn <YOUR IP>
Then press "Scan Now!" button and wait for several seconds. If the port is opened the output must contain:6112/udp open|filtered unknown Of course, you need to login to battle.net before performing the scan.
However it is much slower than StarCraft port tester website that was linked in original post. Moreover "One IP address is allowed to execute Nmap Online no more than 10 times per day."
It requires to download some software, imho not a good way for testing ports. (in addition, it's a windows software and I don't have windows os)

You use Ubuntu? never needed to use port opening for it, but then again never played Broodwar with it (never bodered to learn wine  )
The port detective is the only program which i found 100 % accurate. All the others failed my expectations, sometimes they would say my ports where open when they where not and vice-versa.

Not Ubuntu, but another Linux distro. And yes you are right that you don't need to open ports in Ubuntu as they are already opened. + Show Spoiler +As for wine, nowadays wine does not need to modify any configs for playing BroodWar. However there are some tweaks you may want to do depending on video card you use.
It matters when you play from different locations using different internet providers. Some of them block UDP ports by default.
Anyways, doesn't matter here, because I tried "port detective" software and it always shows my port as "open" regardless the fact that I'm not logged into battle.net. And the program does not allow to select UDP protocol scanning. So I'm curious how you could use this software for checking 6112 UDP port (which is usually, but not always, the reason of problems).

Yes, I did the same thing. But you don't tell is it UDP or TCP port. I believe it shows TCP.
And currently in my configuration TCP is always opened. And there are lots of cases when you have TCP opened and UDP closed at the same port number.

Does the port work? It doesn't work for me can somebody check?

If you have external IP anybody can check your port using nmap utility.

Updated the link + added a link to russian version of this manual.
P.S. Now noone wants to say Starcraft is not dying? xD
