[Unable to log into server hosted on same computer]

Direct connecting to 127.0.0.1 won't use the modem, internet or even network.

 

Minecraft doesn't use any form of Peer to Peer networking, it's pure client-server architecture (even in singleplayer it's connecting to an internal server on 127.0.0.1).

 

Because it's client-server you need some form of port forwarding for port 25565 across the internet - the DMZ is one way of doing that (it just passes all the port requests to a single IP), Hamachi is another way to do that (it's basically a series of DMZs pointed to the hamachi ip addresses if you want to look at it like that).

 

You won't be able to connect or ping your own internet (WAN) IP address or hamachi IP from your own computer, use the local loopback (127.0.0.1) for that.  You may be able to ping your own local IP (192.168.?.? probably) depending on how your network is configured.

 

If the firewall is blocking connections on 25565 and changing that isn't an option, then playing multiplayer isn't an option.  Turning the firewall off temporarily is a way to check to see if it's causing any problems - if it works fine with the firewall off then you need to make some changes to settings in it, if it doesn't make a difference then you can try turning it back on at the end when it's working and seeing if it makes a change then.  You're right in that it's a nice thing to have and keeping it on is more secure than not, but it's not much of a risk to have it off for a short period of time (and in all honesty if someone has the skill to take advantage of the firewall being off then it likely won't make a difference if you're using the standard windows firewall and they want to attack you for some reason).  The windows firewall is capable of blocking local loopback requests, so you can't rule it out just because it's running on the same machine.

This is extremely helpful. Thanks!  

I'll see what I can do. I always was able to log onto a Hamachi server that I hosted on my own computer (vanilla), when I used my old Windows XP dinosaur. Today I learned

[Unable to log into server hosted on same computer]

I have 64-bit Java installed, I have Hamachi running (I used to use it all the time for vanilla servers), and I opened the launch.bat batch file. The server runs perfectly fine from what I can tell; I even scrubbed through all of the forge modloader text files in search for errors and such. When I add a server with my computer IPv4, with or without the server port extension, it is not detected. I even tried to host a vanilla (snapshot) server using Hamachi, and I have encountered the same problem, which leads me to believe it's a computer issue and not the server itself.

I've tried experimenting with every variable I could think of in the server.properties file, but to no avail.

 

Any suggestions, anyone?

 

I'm attempting to run the Attack of the B-Team 1.0.12a version server.

Also, disabling my computer's firewall and not using Hamachi is not an option.

 

Environment: Windows 8 (64 bit), Java 64 bit, decent internet, LogMeIn Hamachi, sugar, spice, and a dose or two of ignorance...

 

(I don't quite expect anybody to be able to tell me exactly what that issue at hand is, but suggestions of things to try is greatly appreciated. I am trying to get this server running for a buddy and I)

[Modpack ID conflicts that I don't know how to fix.]

When I had ID conflicts in my modpack, I just opened the config file for one of the 2 mods that shared that ID, and changed the number to something in the range of suggested numbers. After that, it worked perfectly fine and it didn't cause any problems. That may or may not be the problem, though.

[Custom Server tutorial]

When I download the zip from the 1.6.4 link, chrome (my browser) blocks the file as malicious (malware). Is there somewhere else I can get a template? I think all I really need is the text to go in a .txt document to turn into a batch. I dont actually want to run a server on my PC, but rather make a separate zip file for anyone else to run a server for my modpack.

Thank you so much! works like a charm and is lag free. <3

[Custom Modpack loads as vanilla, and I think I am missing a modpack.jar file]

Your modpack archive needs a folder named "bin" and inside that folder a single file named "modpack.jar". The modpack.jar file is simply the Forge universal binary jar file renamed to modpack.jar.

Would that .jar file be the installer/a different file from the forge website, or the new jar file that forge makes when you install it?

Thank you

[Custom Modpack loads as vanilla, and I think I am missing a modpack.jar file]

I compiled a custom assortment of mods today, and I finally was able to get the pack up and I was able to get the launcher to download the pack from my dropbox. The platform URL is: http://www.technicpack.net/api/modpack/its-a-mages-life . When I click play and the launcher verifies the files and whatnot, the game loads as vanilla. I compared the files I have with the files in my Attack of the B-Team folder. I do not have a modpack.jar in my bin folder. At first I thought that I did not upload a folder that contained Forge, and that may be the case, but I think I am just extremely confused.

In addition, I uploaded my modpack zip folder with a minecraft.jar, which from my own research,I understand is apparently piracy, and that was NOT my intention. lol.

Please excuse my facepalm-worthy ignorance

*Edit* I forgot to mention that I tried the entire assortment of mods in the Vanilla Minecraft launcher, with forge and everything, and it runs fine. When I load the game through Technic, it loads modless.
