I am a premium user of Minecraft.
I continuously run a private server from my home iMac i7 (8Gb RAM).
My workplace utilizes Microsoft System Center Endpoint Protection.
Our computers run IE, Firefox, and Chrome, with full internet browsing capabilities, except for pornography, gambling, dating services, etc.... Minecraft.net is NOT blocked by this service, nor are user-triggered in-browser downloads.
Control Panel is virtually inaccessible. (Message for specific access privileges)
Command Line is blocked without administrator privileges.
Java is not able to be updated by users (tells me that firewall or something is filtering or blocking java in some way.) Also, cannot play java games such as Yahoo! Pool, Euchre, etc.
I want to connect to, and play on my server from work (PCs).
I do not want to perform illegal actions to play Minecraft on my multiplayer server at work.
Server works properly for all users at all other known locations, save here.
I have attempted three different methods of playing the game, which include:
- Normal (Download minecraft.exe from minecraft.net and execute)
= Launcher opens, and takes system information, and then when downloading the .lzma file from the amazonaw5 website, it cannot access the website to download, and tries 10 times before stopping. No further progress toward playing game using this method. **NOTE: I am able to manually navigate to the website/file URL for the .lzma file, and download it successfully. however, I am not able to access the C:/ drive to place the file in the proper location myself, dude to my lack of administrator privileges. Hence, the reasoning for the following method...
- Minecraft Portable, available on this forum. This script basically allows the use of a portable (USB, in this case) Java Runtime Environment, and allows the files that would be downloaded as part of the .lzma package to be stored on the portable device, which in turn allows the game to be played without accessing this website for download. This method allows me to get the launcher working to the GUI stage/login screen. = Upon logging in, I receive a ConnectionTimeoutException: invalid token error, and cannot sign in. I am guessing that this is due to the Minecraft Launcher not being able to connect to the internet. This fits with why I can get this far using Minecraft Portable, but no further. However, this process did succeed using a particular computer here at work once (Not sure how/why, but perhaps it has to do with some sort of issue I have heard described around the forums as resulting from not logging in on a computer previously. I am not sure what this means though.) At this point, I could play online and am only given the button option to "play offline". In addition to this, no tumblr updates are loaded, and it says "Loading page.." forever. This, of course does not work for me, as I want to play online on my multiplayer server with my buddies at home. Again, a sign of lack of internet access for this particular program.
- MinecraftSP.exe. This software generally is used by those who do not want to pay for a license. As mentioned earlier, I do have a license. I have only attempted to use this cracked version, as it averts the need to check in for updates/tokens at login. Using this method, I am able to launch the game normally all the way until I have entered in my server <IP address:25565> in the Multiplayer/Join Server.... box. Here, I am given the following error:
java.net ConnectionTimeoutException: No further information
and cannot connect to the server, but single player works perfectly.
In summary, I am lead to believe that it is only Minecraft that somehow is not getting proper internet connectivity. However, minecraft.net is fully accessible. Any ideas? Help would be greatly appreciated!
Most likely the IT dept have blocked the ports that minecraft and many other games use to stop people playing games at work.
so unless you get them to allow minecraft and java to talk through the blocks in place you will have to work at work and not play on your server
Java is not able to be updated by users (tells me that firewall or something is filtering or blocking java in some way.) Also, cannot play java games such as Yahoo! Pool, Euchre, etc.
Your workplaces firewall is blocking Java, either there needs to be an exception for Java, or you will never be able to connect. Your minecraft (Java) sends out a packet saying "What's happening?" But the said packet never reaches your server because of your firewall.

I thought that the port blocking stuff was just for incoming information? As in it would only be relevant from my home computer, where all user ports are always open and my IP address is constant...
This is a job where I can play games at work, and the internet filter does not have any specific goal of blocking games, just things that are inappropriate as mentioned in OP...
Please enlighten me if I am wrong about this port ideology!

How could I go about this? If you throw out ideas, I will attempt them and let you know results
Thanks!
ports go both ways. they may not be directly blocked, but unless they firewall is set to allow the access to the port then it will be blocked, and no company with an internet connection would leave all its ports open and free, that just asking for hackers, viruses etc.
your best bet would be to chat with the IT guys, never know they may play minecraft too and you can get some new server members
Contact your System Administrator, and ask them, "May I have a program have an exception in our company firewall?" The only other way I can think of is using a VPN, which I think they would not like.
Alright sounds good, Ill get at them tomorrow and let you all know how it went. I'm pretty optimistic as of now though. Thanks!
I was reading over some additional threads that were about java version mismatches, so I've decided to post my home/server launcher info as well just in cast it helps somehow:

In a scenario like this it helps to realize that there are probably multiple different layered security policies that are blocking you, all of which probably need to be worked around before you see success.
For example,
* outbound traffic that is not recognized may be blocked at your corporate firewall. Standard HTTP, HTTPS might work, but some random minecraft server socket may be blocked.
* access to unclassifiable servers might be blocked. i.e. instead of a black list of porn, gambling, dating, etc being blocked the list of all the other categories might be the only thing allowed, so if you navigate to 1.2.3.4 and they have no idea what it is, that might be blocked (under a 'better safe than sorry' policy)
* many programs (e.g. java) might be blocked from any network access by policy [This might explain why you can get the lzma via a browser, but not via the launcher]

Thanks for the advice, as it is more likely than not that this is a complex situation I am dealing with. Good to keep in mind - it is easy to get tunnel-visioned dong this type of thing. Anyway, I was just wondering if that portable Java runtime environment would aery that last point you made with the java blocking? Remember, I was able to play single player using a USB 'Minecraft Portable' launching script...
If you have a functional minecraft installation, and have previously logged in, then you can run single player without any network connectivity. You did say that the Tumblr screen didn't load, right? That shows a lack of connectivity.

Yes, I can play single player, because it does not require a connection. No, the Tumblr screen does not load in the cases described. I just need to figure out the fix for the connectivity issue here.
Set up an SSH server at home on a separate computer on port 22, make sure port 22 is port forwarded (i use WinSSHd)
Download an SSH client (i recommend PuTTY) and go to work.
Enter your home computer's ip in the connection area and select port 22.
Then go to Connection>SSH>Tunnels and enter port 25565 as a Dynamic Auto port.
Save the session in PuTTY so you can use it again later then press the "Open" button.
When you run minecraft it should work
Don't forget to create profiles in WinSSHd, also in the WinSSHd setting go to the Authentication tab and pass authentication to required and public key authentication to disabled.
I would be willing to attempt something like this, if IT does not respond to me in a reasonable amount of time. However, what does this accomplice, in layman's terms? I just want to make sure that it is not malicious/illegal, as I am not looking to get into trouble.
Also, I am curious as to the details of how to go about this. I run my server from my iMac, as described, but it appears that PuTTY is a Windows-based platform of some kind. I do not have access to another computer at home, especially not a PC. However, the only computers that I do have access to at work are PCs, just to make that all clearer. Thanks!
