FTP Problem
Amit Batra
I am a newcomer to the world of AIX. The ftp daemon is running on my
machine, but it does not allow anybody (not even root) to ftp to my machine.
How can I allow people to ftp to my AIX machine?
Somebody suggested including the usernames in the /etc/ftpusers file.
But I have seen that no such file exists on another server running here
(although it does allow us to do ftp on it). Urgent help is required.

Before the ftpd daemon can transfer files for a client process, it must
authenticate the client process. The ftpd daemon authenticates client
processes according to these rules:
The user must have a password in the password database,
/etc/security/passwd. (If the user's password is not null, the client
process must provide that password.)
The user name must not appear in the /etc/ftpusers file. Leave this file
empty.
The user's login shell must appear in the shells attribute of the
/etc/security/login.cfg file.
If the user name is anonymous or ftp, an anonymous FTP account must be
defined in the password file. In this case, the client process is allowed to
log in using any password. By convention, the password is the name of the
client host. The ftpd daemon takes special measures to restrict access by
the client process to the anonymous account.

In fact, there is no need to have a /etc/ftpusers at all.
However, are you really sure that ftpd comes up if a user tries to
log in ?
What happens exactly if you try to get connected by 'ftp' ?
Do you have access if you log in directly on the server (Use the
command 'ftp localhost') ? You should see the following:

The same message appears if anybody tries to login as a normal user. Can you
tell me what the problem could be?

Now this is funny. Can you ftp to another machine ? Can another
machine ftp to your box ?
Perhaps something is broken with the client and not the server.

From my machine (ie sambhaj, whose output I had produced earlier), I am
able to ftp other machines, but nobody is able to ftp to my machine (not
even me, the root). I checked /etc/ftpusers file, it does not exist on my
machine (also not on other machines to which we can successfully ftp).
I am in a fix. Please help me.
Thanks,
Amit

The problem is solved. The problem was in the /etc/security/login.cfg
file. This file contains the path of the login shells of each user. We had
re-compiled bash on AIX and all users were using bash as there login shell.
But its entry did not exist in the /etc/security/login.cfg file.
After the entry was made (just 2 minutes ago), ftp is running like
magic. Thanks a lot to both of you for helping me, especially to Charles who
pointed out this problem in the first place.
