vsftpd uses login 'nobody' to run unprivileged bits of itself. By default, user 'nobody' has a GID of -2, which is probably making setgid() fail.

Either change GID of user 'nobody' or modify vsftpd.conf setting 'nopriv_user' from 'nobody' to another unprivileged account.

Shalom Matheiu,

ftpd servers know nothing but numeric user id's. They get response based on the permissions of the user that is connecting.

If you are user sprotter at log in, the ftpd server sees you only by your numeric id on the host system.

So, if you have vsftpd configured to say disallow root ftp access, which is a really great security idea then these kind of results should be expected.
