Thanks. We'll let you know when a new response is added.

The AS400 command is a little bit different that DOS.

AS400 command:<b> PING RMTSYS(usrias01) </b> if you type PING and press F4 you’ll see additional parameters as well.

If you find you still can’t ping your server try using the trace route command.
<b>TRCTCPRTE usrias01</b>

That should help you find the failure. Perhaps there’s an issue with your network and you don’t know what hop it’s on. The trace route will help you locate the failure.

<b>If your issue is orginating on a PC.. Then the above commands won’t help you.</b>

PC instructions:
Try flushing your DNS cache: CMD:<b> IPCONFIG /FLUSHDNS</b>
Then try to ping the server again by name.
If that fails try to ping the server by IP address.

From a Windows CMD prompt use the command <b>TRACERT usrias01</b>
The output will display the network hops and list the IP addresses and response times.

With the<b> Trace Route results</b> either from PC or AS400… Take those results to your network admin. By knowing the last good hop of the route and the hop that’s failing you should be able to identify what segment of the network is failing. If you make it all the way to the final hop to the switch housing the AS400 then you may have a faulty port, bad cable, or server issue.

Hi,

Do you know the real IP address of the<b> <i>usrias01</i></b> server?

Please try to ping that server by it’s IP address.

If the result is ok, i.e. you have a real response form the server, the problem might be in DNS. The DNS server can have no host configured with that name, or it might be mispelled. It can also be the machine you’re using to test this is not using the right DNS server…

If you ping that server by it’s IP address and even so you can’t get any reply from it, the problem might be a firewall, router ACL, etc preventing it form receiving ping’s or answering ICMP echo requests (answer the ping command)

Please post back any update.

    Error--"No response from host within 1 seconds for connection verification 2." What happened with verification #1 or #3? How many verifications were attempted? How many failed? Did any succeed? If you run PING against that system a few times with a few minutes between, do the numbers of successes and failures change? Are the two systems in the same network? Or is there routing between them? If they are on different networks, is the route between them an internet route or is it entirely within your organization's control? Without knowing a lot more about how the problem was encountered and how the entire route is configured between the two systems, there isn't much anybody can say about fixing it. So far, it looks perfectly normal. PING isn't guaranteed to be successful. I'd suggest that you not use PING. Replace it with programming that actually tries connections to the server ports that you need. Tom

    don’t use host table entries! DNS DNS DNS =) DNS entries should be preferred when they are available. When they're not available, a host table entry is fine. Many of us have no control over the entries that populate DNS servers. I've often had systems that were accessible through internet routes but only by IP address. Since those systems never had DNS entries, it would do no good to rely on a DNS server. Either you used the appropriate IP address or you added an entry to your system's host table. A host table entry can be the best choice in numerous circumstances. Tom

    I find the Host table entries on i most usefull because they are often needed to resolve names to IP adresses for processes that are carried out on i before going to the network. The Host Names help a lot when the Network changes and devices change IP adresses. On i only the Host table needs changing and one doesn't have to go through all configurations where IP adresses iso Host names are used.

    I second that @Carlosdl. ! We're all trying to figure not so well described scenarios and problems and after giving a bunch of suggestions, all we get is: "Thanks a lot , Now its working ..". @Sms121 Don't take this personally and don't get me wrong, but this kind of thanks suggests me that the problem was something similar to a disconnected ethernet cable... I am always learning here and there reading questions and answers on foruns, blogs, etc all over the world. If every solution was answered that way, no one else can learn with that experience. Approving an answer or sharing the correct solution is a way of all people that read, reply and will search this forum for a problem like your's, to learn.
