I'm newly moving from a Linux working environment to Windows, and I'm mainly using local port forwarding+Pycharm to run my python code on a server that is double-hop from my laptop.
I am able to establish the ssh tunnel through Windows cmd or MobaXterm local terminal or MobaXterm tunneling tool. I works fine on my Pycharm, when I check it from tools/deployment/configuration/test connection, and I can also see the files in remote server. But every time I start my Pycharm, it shows two background process, "updating python interpreter" and "updating pycharm helper", and the precess bar simply do not show any moving on! And I cannot run python on remote server, because Pycharm says I lack python helper.
And most wired, when it is running these two precess, my terminal for local port forwarding freezes, and I cannot type in commands in the jump server. And when I try to recheck the connection, it turns out that connection fails.
My ssh tunneling+pycharm deployment used to work fine in my Ubuntu. Thanks anybody who can shed light on my confusion!
Well, thanks everyone, I have solved this problem.
The reason is simple, but I did not notice that the ~/.pycharm_helper 's size is actually changing in the process, while the GUI bar may be not moving.
So it is due to my double-hop inconvenience, and the low Internet speed. I left it in dorm for a whole night out, and it comes out just fine.
I have been trying to get Raknet up and running on my Raspberry Pi (2).
I am using a simple client server test program to connect from my windows machine to my raspberry pi. Using tshark on the Pi I can see that all message are arriving on the Pi. However, the server application does not seem to pick those up. As far as I can deduce all ports are open, the machines are on the same network, the code is correct (taken from some github repo with examples for raknet).
The frustrating thing is that a while back I though I solved this communication by starting my server app as root (sudo). However, in the meantime something has been changed in my setup which makes this no longer the case. Any help is appreciated.
I completely forgot about my question here. It actually had to do with privileges on the networks we use here. I had been testing on two different networks without realizing. Problem has been solved.
I recently bought a Raspberry Pi 3 Model B and started to set it up. I followed some tutorials and finally was able to access it remotely without having to plug it to a monitor, a keyboard, a mouse...
Everything is okay but it just bothers me a little bit that whenever I reboot it or I don't use it for some time I have to ping it on the computer before being able to control it remotely. If I don't ping it, connection fails.
It's not a big problem but is something I'd like to be solved. Thank you for your attention!
UPDATE: Just did a clean installation and now it works fine and can be accessed remotely at any time. Thanks to anybody that tried to help!
I am doing a multiplayer game using UDP protocol (DatagramSocket and DatagramPacket). The program has to do client and server at the same time. This works fine on LAN networks, but I would like to make it work on Internet too. I have tried to use hamachi, but it doesn't work, the information goes only in one direction.
EDIT: Ok, I ask in another way. Is there any java class, program or anything else to connect two computers on internet using java?
Ok, I have just resolved the problem. It works fine with hamachi. I was copying wrong IP's, so it didn't work. If you exchange your IP's to each other, It works.
I want to make my raspberry pi (reaspbian) available from the internet via ssh.
Locally it is not a problem, but after asigning a public ip (router is thomson TG789vn) it does not work anymore.
also not from the local network. theres always a timeout error.
The strange thing is that i tried it some months ago and it worked and now i really don't know what to do to fix it.
Check your internet connection and the LED on the front. As well make sure it is configured correctly. Pi's are very barebones and do not have the comprehension that windows has to fix all the little problems.
