TCP/IP Services FTP Connection Limit?

» close window

The Question is:

 
We are running an FTP server and sometimes the FTP server stops responding. We
 found that the server at that moment receives more that eight requests per
 second.
 
Here are some messages we get:
 
%TCPIP-I-FTP_SESCON, FTP SERVER: session connection from 192.168.130.220 at

In the tuning and troubleshooting guide, it is suggested that the default
 connection request limit should be raised (section 2.2.3, page 2-16)
 
We looked through all documentation, but could not find a clue on how to do this.
 
We think it has also to do with the 500 connection requests per minute limit ,
 but no trace about any logical to be set.
 
Can anyone get us going again?
 
Thanks,

The Answer is :

 
  Please first ensure you have the currentTCP/IP Services version and
  ECO installed.
 
  As for the connection limit, use the4 TCPIP utility to display the
  FTP service (SHOW SERVICE FTP/FULL) and to alter the limit (SET
  SERVICE FTP/LIMIT=n).
