I had this problem today with everything up to date. I switched hdmi output and fixed the issue. I switched back to the previous hdmi to double check and the black screen problem returned. It seems to work on the hdmi closest to the power conector.

So please correct me if I'm misunderstanding you. You are connecting remotely to your Pi via a VPN and then trying to browse the internet. Are you forwarding the VPN connection through a router to your Pi or is the VPN connected to your network via the router? Good question. I'm not sure. I have a ...

Sorry for not being specific. I will start all over and tell you the story of my lazy life. But things have changed since I started this thread, because ftp passive connection do work now with ufw enabled. I have a raspberry pi, at home, with raspbian 10 buster. It has openvpn (using the pivpn insta...

Ok, I don't understand a thing. I have had to re-install raspbian because it wouldn't boot. After setting it all up again, and making sure it functioned correctly, I enabled ufw. sudo ufw allow 22 sudo ufw allow 1194 sudo ufw default dent sudo ufw enable The ftp uploads and downloads in passive mode...

Thank you guys. The ftp I'm using I believe is passive. If I'm not mistaken, ufw default deny I think only affects the inwards direction. I think it's ufw default deny outgoing for outwards traffic. Openvpn by default uses udp, but I have set it to tcp. It works. That's not the problem. I tried your...

In debian I entered: sudo ufw allow 22 for ssh and sudo ufw allow 1194 for openvpn. I also set it to sudo ufw default deny . And ftp uploading and downloading just works. On the raspberry it doesn't work. That's why, as an ignorant user I am, I entered all types of stuff like: sudo ufw allow 21 . su...

Yes, I've just read about passive and active ftp connections. I had no idea about that. I'm now trying to figure out what port range is open on the ftp server. I might as well just ring the server administrators. But I still don't understand why ufw doesn't block the random port connections on debia...

Thank you very much for your answers. The rules I have are the ones I have posted. Just copied and pasted the output of "sudo ufw numbered verbose". I started off just entering the rules I entered on my debian pc, and while that works on debian it does not on the raspberry. I further added more rule...

Finding an alternative to ftp seems like the best way forward? No. I do not own the ftp servers I fetch files from or send files to. It's their administrator's decision, and I need to work with them as is. I already mentioned some time ago that they weren't encrypting their user or password, but th...

Hello friends. I have a raspberry with raspbian buster, which I believe to be based on debian 10. I have it with openssh-server and openvpn running. I have a script that downloads and uploads to different ftp servers that are not mine. The script is triggered using cron. I am using wget and curl. No...
