I installed ubuntu 13.04 64bit on AMD CPU 64bit machine. then installed vsftpd too.
but always returns 530 error code when I connect to server.
so I googled about this problem.
There is another vsftpd package that works on AMD 64bit CPU sombody patched.
before I use patched vsftpd, I couldn’t find a log at /var/log/vsftp.log
but patched package prints a log but I can’t connect to server.
There are so many ISP runs AMD 64bit CPU for their Virtual Machines.
