You can use telnet, ping and traceroute to probe server ports. You don't have to rely on the Earthworm
software only. For example, if the server that export_generic is
trying to reach uses port 16002 at IP address 192.168.0.2, can you
telnet 192.168.0.2 16002? If the server is listening, telnet will
connect, even though it will not be able to communicate. If that fails,
can you ping the server IP address? I.e., ping 192.168.0.2. If that
fails, you have network configuration errors. You can use traceroute to
watch what the ping probe is doing. I.e., traceroute 192.168.0.2.
Assuming you had no need to change port numbers, the fact
that export_generic says it cannot connect is a pretty strong indication
the network is not quite configured properly on one or more of your
systems. Have you examined the firewall rules on your systems? If NFS
is involved, make sure the server export rules allow the mounts you
need. Use showmount -e <server-IP-address> to show the export
rules for the NFS server at <server-IP-address>.
So I am able to ping and ssh to the device on either network, during what I will refer to as the pub-blockout. The network was switched over to the private network. I was still able to ssh from server to all connected devices. That's how I was able to make the network changes on each device... The Network Attached storage(NAS) device is unix based and runs debian squeeze. I ran the netstat -a option on both networks so you could also have a comparison(please see attached file) the netstat_uwi-Net is the public network. Also once the pub-network was restored and the ip addresses were reverted everything started to work again i.e writing to the database remotely resumed.. Secondly I also have the same situation on a new server that I just set up. however the database is local, the buffer that I'm using to write from is empty. The getmenu command says nothing is in the server, but the buffer I'm pulling from has data.
The data in the wave_ring buffer is from an import module:
