RE: [TMF4.1.1] lowlevel command to obtain endpoint ip address on NAT enable: msg#00550sysutils.tivoli.tme10
Hi Brain, Your strategy does sound good, but I don't think it quiet answers my dilemma. I am designing an automated endpoint installation solution. Part of this solution involves running pre-install prerequisites (i.e. run before allowing TMA code for installing an endpoint to execute on the target machine). One of these pre-install prerequisites is ensuring there isn't an endpoint instance in the TME bearing the same name as the FQDN name of the target machine. A cgi script does this instance check through the Tivoli Web Access component, and if it does find an endpoint instance for the machine a person is trying to install the TMA code on, it adds that problem to a report to feedback to the installer for further analysis. Now within this entry of the report, I would have wanted to include the IP ADDRESS of the endpoint instance found as part of the record. And that so far seems not possible using Tivoli commands, at least that's what I've gathered based on the great feedback the LIST has bounced on me. The solution pulls down the TMA code from a central store to the target machine only when all the pre-install prereqs have been performed and are successful. The above is one check the many checks we don't want to allow the TMA code to be installed on the target machine before its satisfied because that leads to a lot of other problems as I am sure you have experienced with your Tivoli environments. Hopefully the above is clear.

Joel - The way that we handle these sort of situations is with a "penalty box". When new machines login to the TME, we first leave them assigned to the intercepting or seed gateway in the Hub region (ie penalty box). Then we check various things on the endpoint (dns resolution, are apps that break Tivoli on the endpoint, etc) and migrate the machine to its proper gateway in one of the spoke regions. The advantage of this technique is that we can run tasks and check for more problems than you can with allow_install policies. The disadvantage is that there is a lag between when an endpoint initially logs into the TME and when it is actually assigned to its actual gateway to utilize Tivoli services. You could easily use something like this to verify the IP or even MAC address of workstations to find duplicate machines. Brian Duffy

There are various ways that can be determined to get the IP Address "if" the endpoint's lcfd service/deamon is running on a machine! But let's consider a scenario where, there's no TMA code at the endpoint machine or the lcfd is not running, only the instance exists in the TME. My question is based on this scenario.

Why not just create a task that ran a command (ipconfig) to tell you what the IP address is. Then execute the task on the endpoint. The IP address should be in the STDOUT.

From Gary's explanation, the IP of an endpoint instance in a NAT enable TME is not available from any object database or registry on the TME. Your explanation does make sense, unfortunately it only confirms my fears! Looks like I'll have to abandon the thought, unless someone comes up with some magical way of achieving the objective( to provide the installer with more information for further analysis when/where needed). Thanks for all your swift assistance gents. Keep well and on track.

So you are asking for the real address of the endpoint that is on the other side of a NAT firewall? This information would not be available to the Endpoint Manager. In a configuration like this, you would be using the name of the endpoint to communicate with it, and the name is converted by the appropriate naming service to an IP address, which will be converted to the real address when it passes through the firewall. An IP address may be stored in the Endpoint Manager database, but this address is very likely to be the NAT'd address, not the real one. Is this the IP address you are asking for? Gary R.
