Problems starting the Aurea List Manager server

Find below a major problem that might prevent Aurea List Manager from starting:

Error message about Invalid host

When starting Aurea List Manager, if you receive an error message about Invalid host, then the problem is likely with your TCP/IP machine name configuration.

This problem is usually caused by an incomplete DNS configuration. In order for Aurea List Manager to work, the TCP/IP hostname on your machine must exist on your DNS server, and the TCP/IP addresses that your machine uses must themselves have names. In technical terms, this means that you need both forward and reverse DNS lookups installed on your system.

Follow the steps below to resolve the issue:

  1. Check the hostname/domain name that you have set in your TCP/IP configuration. Make sure that you can ping this full name, both from your machine and from another machine.
  2. You must have a DNS entry for your machine on your DNS server. This hostname/domain-name setup is usually the cause of your problem.
  3. If you have multiple TCP/IP addresses, make sure that the first TCP/IP address on your system has a DNS name entry.
  4. With the program nslookup.exe on Windows and nslookup on UNIX, you can check to see if DNS entries are set up correctly.
  5. If your computer is named fia.yourcompany.com, you need to type: nslookup fia.yourcompany.com For example: C:\>nslookup fia.yourcompany.com
  6. And nslookup responds with:

Server: kuno.yourcompany.com <- this is your DNS server.

Address: 207.105.6.156 <- this is your DNS server.

Name: fia.yourcompany.com <- this is your hostname.

Address: 207.105.6.147 <- your TCP/IP address.

  1. If your DNS is not set up correctly, this forward lookup responds with:

*** kuno.yourcompany.com can't find fia.yourcompany.com: Non-existent host/domain

  1. If it did work and you did not get an error message, now do a reverse lookup by typing the TCP/IP address of your machine. For example, if the TCP/IP address of your machine is 207.105.6.147, you need to type: C:\>nslookup 207.105.6.147

Server: kuno.yourcompany.com - this is your DNS server.

Address: 207.105.6.156 <- this is your DNS server.

Name: fia.yourcompany.com <- your hostname.

Address: 207.105.6.147 <- your TCP/IP address

  1. If your DNS is not set up correctly, the reverse lookup responds with:

*** kuno.yourcompany.com can't find fia.yourcompany.com: Non-existent host/domain

  1. If you do have a DNS problem, you should contact the person responsible for your DNS. In most cases, this is your Internet Service Provider. Once this is fixed, the issue is resolved automatically.

Note

If you have multiple TCP/IP addresses and only want Aurea List Manager to use some of them, check Problems With Multiple TCP/IP Addresses for more information.
