FTP login failed.

Hi guys, Can you please help me.

I have SUN V100 server running solaris 8.

I also have a Redhat Linux 6.2 machine and a windows XP machine on the network.

I'm trying to copy files from the Linux and XP machines to the V100 server.
When I try to ftp to the solaris machine, I'm challenged for a username and password.
I supply the correct credentials but I get the Error 530: Login Failed Message.

It is the same from the XP machine and the Linux machine.

Can someone please describe all the bits that need to be in place before I can make an FTP transfer?

I tried a Google search and a search on these forums and neither yielded any useful information.

Many thanks in anticipation.

EDIT:
I can now ftp as root (comment out root in /etc/ftpusers and comment out the CONSOLE line of /etc/default/login
However Id really like to be able to FTP as a regular user.

Can anyone please help?

check that your regular/root user has a valid shell in the /etc/passwd file and its stated in the /etc/shells file as well

I think you restart ftp service on server.

Correctly configure the configuration file on the server(For Linux).
