RE: Turn off PING server on AS/400

Or use Ops Navigator (iSeries Navigator, whatever...) to setup Packet
rules....  I think you would want to set a filter on ICMP service....

There used to be an IBM firewall product for the iseries.  Dropped a few 
releases back.
Current strategy is:
1-External appliance (such as a cisco firewall)
2-Linux partition
3-Integrated xseries server

RE: Turn off PING server on AS/400






Thanks Scott.

I have an AS/400 that I want to put on the Internet for a specific 
purpose.
I only want to have one port open, which I will handle with a socket 
server
program. I will turn all other TCP/IP servers off, including telnet.

Are you taking about an  external firewall, such as router? I wasn't
planning on using a router but I could if I have to.

Or is there a firewall on the AS/400 I can use?

                 Ping is a little bit different from other TCP/IP 
applications, in
that
                 there's no "ping server."  Ping is implemented at a 
lower-level,
it's part
                 of the TCP/IP stack itself.

                 The best way to disable it is by blocking ICMP echo 
packets with a
                 firewall.

                 Can I ask why you want to disable it?
