Ubuntu server and ubuntu with netbeans переизречение connection: upload permission denied

I have в project on в переизречение server (ubuntu server 15.04). I хан download my поля from /var/www/html with не problem. But I can't change and reupload them. I get permission denied when renaming в dir or file, upload в new file or deleting an existing file.

I make my connection with SFTP and I start конечный Netbeans from the with sudo. I also checked Предохранил переизречение Филе Пермиссионс in the Run configuration.

Схвати в last resort I have installed vsftpd on the Веб server and followed steps to add в user. Again, connecting with the user credentials and downloading works умер but uploading doesn't at all.

My goal is to connect схвати в user with enough permissions to change or upload new поля and directories but предохраните the orginal permissions on the server.

Хан anybody shed some light on my problem?

thanks Томас
