Ping/FTP to active IP address

[Steven.Gray@xxxxxxxxxxxxxx]

Thanks for your responses,

You have the address in single quotes, right?   ping '127.0.0.1'  ?
(can you ping localhost, by the way?)
                
        Yes , the ping was in quotes , Yes I can ping the local host , all
my other IP routes are fine and I can ping these.


You said you have added a host table entry, but not whether you have added
a routing entry (different screen).

        Sorry , I did mean to say that the IP address was added to the
routing table (ADDTCPRRTE) rather than the Host table , My mistake.

        The entry being 
        Route                   Subnet                  Next
Route     
Destination             Mask                    Hop
Available 
        172.30.128.10                   *HOST
172.30.195.243             *YES         

        The next hop being my default gateway
        With the binding interface set as my AS400 address.
        
        I do have an entry for a default route

        *DFTROUTE                       *NONE
172.30.195.243             *YES         

        This however makes no difference.

Could there be a firewall which is allowing some IPs to do the ping, and
some not to?

        Reply from my Comms guy,
        At no time do you go near the firewall. There are no filters or
restrictions on this link. If a device can get to Dublin from Swindon with
the same default gateway as the AS400 then any device will be able to get to
Dublin as the routers are not device specific.

Two machines with the same IP address?

        With help from my comms guy , we logged onto the destinations router
and tried ping'ing back to the AS400 which worked fine. To check if this was
the correct box (i.e was there more than 1 with the same IP address) we used
a telnet session , this showed the AS400 sign on screen. Therefore we were
ping'ing the correct box.
