Troubleshooting
Problem
Installing the Deployment Engine fresh, or an upgrade failed because the DNS entries in the resolv.conf file were incorrect: Error connecting to server 127.0.0.1 on port 4130 with message A remote host refused an attempted connect operation.
Symptom
Manual install of the Deployment Engine will fail with the port 4130 error, and with a DE upgrade from a product install, the same errors will be in the de_install.log and de_trace.log
Cause
Incorrect entry in the /etc/resolv.conf DNS configuration file.
Environment
AIX server, both installing DE manually and as a part of a IBM product install.

Resolving The Problem
Check these three configuration files follow the correct DNS configurations:
/etc/netsvc.conf
-----------------
hosts=local
/etc/resolv.conf ( the "search" line defines the list of domains to search when resolving a name )
-------------------------------------------------------------------------------------------------------------
search hostname.com
nameserver <server_IP>
nameserver <server_IP>
Where "hostname.com" is the name of the Domain.
/etc/hosts
-------------
127.0.0.1 localhost.localdomain localhost loopback
::1 localhost6.localdomain6 localhost6
<server_IP> alias_name.hostname.com alias_name
Where "server_IP" is the IP address of the local server, and "hostname.com" is the domain name.
