 ftp error: 421 Service not available
I have a Redhat 6.1 box and I have recently experianced a problem connecting
to the machine via ftp.  I get the error:

421 Service not available

when trying to connect to my machine.  I have been successfully connecting
to the box via ftp for about 4 months.  This error occurs before a login
prompt or password prompt, and it happens when I am ftping remotely or
trying it from the console (ftping to localhost).

My /etc/inetd.conf line for ftp looks like this:

ftp     stream  tcp     nowait  root    /usr/sbin/tcpd  in.ftpd -a -l

in.ftpd is really wu-ftpd-2.6.0-3.

I do have a line for in.ftpd in my hosts.allow file (I disallow everything
in hosts.deny) but I commented this out, restarted inetd, and that had no
effect on my situation.  I can ssh into the machine fine (along with httpd
access) and those are restricted as well.

I do have a ftpaccess file (which is switched on by the -a switch in my
/etc/inetd.conf file).  It has not changed since I could connect via ftp.

I can do reverse lookups on both my server and the remote machine I'm trying
to connect from, so I don't think it's a DNS issue (ssh uses reverse lookups
also, so I don't think that's the problem)

I'm stumped!  Can anyone give me a suggestion on what to do or look for?

Thanks!!
