Linux Server: Cannot upload files to any directory

Apache2configurationlinuxupload

I am working with an ubuntu server running apache2 but I can't upload files, but I can log in to ssh and
touch test.txt
When I log in to the server with filezilla and try to add a file to /var/www I get a 550: Permission denied error.

The server admin is away so asking is not a possibility but he did give me sudo privs before he left. He set up the server in a hurry so is there something I can do that he may have forgotten that is basic or advanced?

It's the issue with others, which is 0, nothing permitted. I assume you logged in server with permitted user but ftp user is probably stuck with others permission.
