Dale & Mary, thanks
The TP is claiming that the dynamic IP is the problem. I 'ping' client AS2 servers regularly, to make sure that they are online. If they are not, then an email is sent to the admin... I suspect some kind of 'caching' problem. I am not familiar with the DNS TTL (Time To Live) settings, but it may be possible that the TP is storing the current IP in their DNS server, and when the client's IP changes, the TP is still pointing to the old (and incorrect) IP. They have limited control over their DNS server, so I have to be sure about the problem and possible solutions. I would like to resolve the problem without involving the TP too much, if possible. The last resort would be to tell my client to obtain a fixed IP... -------------- Original message --------------- Date sent: Thu, 05 Apr 2007 11:06:58 -0500 From: "Mary DeGroot" <[EMAIL PROTECTED]> To: "Earl Wertheimer" <[EMAIL PROTECTED]> Send reply to: [EMAIL PROTECTED] Subject: Re: [EDI-L] AS2 and Dynamic IPs If BizLink is not using an HTTP proxy, it is using the DNS services on the local machine to resolve the URL to an IP address. In this case, the TP should go to the BizLink machine and try to access your URL. Take BizLink out of the picture by trying these things: 1. Try to access the URL through a browser window. The AS2 servers that I have used will usually come back with a splash screen or some sort of indication that you've hit an AS2 server when using a browser. If it goes through with the browser on the BizLink machine, then it's a BizLink problem. The problem might be with how they entered the URL into BizLink since the only difference in resolving the URL would be with the URL entered. If you can't get through via the browser, it's probably a DNS service/network issue. 2. Try to ping or tracert the URL from the BizLink machine. Ping should at least resolve to your current IP address even if ping is turned off on your server. Tracert should go through to your current IP address. Again, if it doesn't go through they probably have a DNS services / network issue. If the BizLink machine is pointing to a forward HTTP proxy, then they need to do the above tests from the HTTP proxy machine. They should also try to access the URL from a browser on the BizLink machine. The browser needs to be configured to use the forward HTTP proxy that the BizLink machine is using. Make sure that they can get through their proxy and to your URL. They need to make sure that the HTTP proxy is set up properly (proxy URL, proxy User ID, proxy password) in BizLink and that the outbound transport for you is configured to use the proxy.
