Q

iSeries and LAN are not playing nice

This user acquired a used iSeries and he was having trouble getting it to talk to his LAN. Systems management expert Glen Bunnell has some suggestions.

I have acquired a used iSeries and I'm having a bit of trouble getting it to talk to my LAN and was wondering if you could help me.

I have done the following:

The card is up and the TCP/IP interface is active. I have defined two interfaces, Loopback (127.0.0.1) and the box itself (192.168.1.109) both of which are active. I have defined a default route of 192.168.1.1 that is the router address -- there are no port restrictions or remote systems defined. However, when I try to ping either the router or any other PC on the LAN, the iSeries does not find them and it times out. I can ping the router from my own PC so it is not the router blocking the ping. Likewise, I can not ping the iSeries from my PC. I have a green light on the router for the port the iSeries is plugged into. I believe that implies the cable is OK. The box was previously on a LAN and worked, so it seems a bit bizarre that it is not doing so now. Do you have any ideas of what I might have missed or what I can try? Obviously, an iSeries that can't talk to a network is a very expensive door stop.

I'll assume you have the interface assigned to an Ethernet line and you are pinging by IP address. Did you check the TCP domain information along with the subnet mask? I would start with CFGTCP and check every option -- especially options 1, 2, 10, and 12.
