Unix clients refused, Windows clients allowed...

Hi all,

 

  I have a server running Solaris 8 and wu-ftpd 2.6.2 (through tcp
wrappers) that I'm having some trouble with.  I can connect with a
Windows client, from a Windows command prompt, or from a telnet session
from a Windows box.  I cannot connect from a *nix ftp client or through
telnet from a *nix command prompt.  The error message I get from the
*nix ftp client is: 

 

421: Service not available, remote server has closed connection

 

TCPWrappers does not log a connection attempt for the *nix clients,
although it does log connections from the Windows clients.  

 

I am running the wu-ftpd server from inetd with the following line:

 

ftp     stream  tcp     nowait  root    /usr/local/bin/tcpd    in.ftpd
-a

 

A port scan from another *nix machine shows port 21 open for ftp.

 

Has anyone seen this type of behaviour before? Can anyone suggest
something?  I'm running out of ideas. 

 

Thanks in advance,

 

-Tom
