EZA1551I - Unknown host: aa.bb.com
Hello All. When I am try to FTP to aa.bb.com I receive error messages that are in the last 2 lines of this output. JCL follows the output. My Question: The company that I'm FTP'ng to gave me the address. They told me that the error message was due to their name not being in a file at my site. My site tells me that the address they gave me is not know to the Internet and that is why I am getting the error messages. Will someone help me with this? TIA Std.

Carol, Have you tried adding a SYSTCPD DD to your batch job? (Copy what's in your TCP/IP address space.) You may need to specify that information in order to direct FTP to the IP address of your company's name server. Greg Shirey Ben E.

It sounds like your people and their people are telling you the same thing in different words. Site ftp.aa.bb.com is apparently a private host name, not known to the public internet DNS system. And so to reach it, you will have to add an entry to the host table on your end that maps ftp.aa.bb.com to its IP address. That IP address must be a publicly routable IP address or else you won't be able to reach it no matter what you do.

And it could not find any local host files/DSNs either. Oh! Double aha! From Global Tcp/Ip Dataset = None Default Tcp/Ip Dataset = None Local Tcp/Ip Dataset = None I see you have no TCPDATA. No global or default TCPDATA specified in RESOLVER parms and no SYSTCPD DD statement in the jobstream. Your TCP/IP system programmers need to be shot (unless they are you, of course). There are a number of ways to provide TCPDATA for the installation. The easiest is probably to allocate SYS1.TCPPARMS(TCPDATA) - one of the datasets the TCP/IP stack will look for and dynamically allocate. (The are LOTS of alternative techniques. Too many for the topic to be called "straightforward".) I can't give suggestions for the contents of TCPDATA; it is mostly site- specific. Hopefully this is from an environment that missed getting set up correctly, and you have other environments you can model it on. Good luck.

Re: EZA1551I - Unknown host: aa.bb.com
Carol I'm making this analysis with the hindsight which Pat has provided by requiring you to perform a "resolver" trace - one of his favourite traces :-) - and this contribution is a lot about what should have happened. This looks like you were given a job to do which included this FTP job. You are not one of the Communications Server (CS) IP system programmers (or you wouldn't need to ask "your site") and this is the first time anyone at "your site" has ever tried to use the CS IP FTP client - or, perhaps, any CS IP address space which needs to use the "resolver". It may even be that this is the first time CS IP has been used at your site although that confident reply from "your site" - I assume your CS IP system programmers - that the partner is not known to the Internet indicates that they thought they had set up CS IP fully already. Actually they may have meant "to a name server in the Internet" rather than just "the Internet". When "your site" people denied that your partner existed, what you should have done is ask your partner for his/her IP address to try in place of the name. That would have got you past any problems translating the name to an IP address. This is standard IP debugging practice and really "your site" people should have suggested this rather than issuing their flat denial. You need to know that you can always[1] replace a name with an IP address - try it with your web browser some time. Since your partner suggested that a name was missing from a file at your site, he/she presumably was aware that the name ftp.aa.bb.com - or whatever it really is - could not be found in the name server system. If some information is needed in a file at "your site", all the necessary information should have been provided by him/her and that information would have been the name and the associated IP address. Now that Pat has helped determine that your "resolver" environment is somewhat underdeveloped we can proceed. An important question to ask is whether or not this FTP job really requires you to use a name. If this FTP connection is not one that *requires* a name to be established in name servers in the Internet, you may as well just use the IP address. The reason I suggest this is that with an undeveloped "resolver" environment, building a local name file is a bit of a pain[2] and may as well be avoided if not really necessary for just one address. If you had a well-developed "resolver" environment which allowed an up-to-date format for the modern equivalent of the local name file, adding one (the first?) name to IP address mapping would be a "piece of cake". If the answer to the question is that you - "your site" - would really like to have name to IP address mapping in local files as required, then we could recommend getting current with the way the "resolver" should be set up these days. Please let us know. Meantime, get the IP address for your partner and you can get on with the FTP job. On review, I started to worry that maybe your site and your partner's site used int*ra*nets with "network address translation" (NAT) IN ORDER to provide access to the Int*er*net..

Don't know if anyone has suggested this since I've not followed the thread too closely.

This looks like you were given a job to do which included this FTP job. You are not one of the Communications Server (CS) IP system programmers (or you wouldn't need to ask "your site") and this is the first time anyone at "your site" has ever tried to use the CS IP FTP client - or, perhaps, any CS IP address space which needs to use the "resolver". It may even be that this is the first time CS IP has been used at your site although that confident reply from "your site" - I assume your CS IP system programmers - that the partner is not known to the Internet indicates that they thought they had set up CS IP fully already. Actually they may have meant "to a name server in the Internet" rather than just "the Internet". When "your site" people denied that your partner existed, what you should have done is ask your partner for his/her IP address to try in place of the name. That would have got you past any problems translating the name to an IP address. This is standard IP debugging practice and really "your site" people should have suggested this rather than issuing their flat denial. You need to know that you can always[1] replace a name with an IP address - try it with your web browser some time. Since your partner suggested that a name was missing from a file at your site, he/she presumably was aware that the name ftp.aa.bb.com - or whatever it really is - could not be found in the name server system. If some information is needed in a file at "your site", all the necessary information should have been provided by him/her and that information would have been the name and the associated IP address. Now that Pat has helped determine that your "resolver" environment is somewhat underdeveloped we can proceed. An important question to ask is whether or not this FTP job really requires you to use a name. If this FTP connection is not one that *requires* a name to be established in name servers in the Internet, you may as well just use the IP address. The reason I suggest this is that with an undeveloped "resolver" environment, building a local name file is a bit of a pain[2] and may as well be avoided if not really necessary for just one address.

But definitely check that this is allowed by your site. At some shops (like mine) that prohibit use of IP addresses you will also find "hosts" files prohibited, and for the same reason.
