Why are my BigFix Clients not choosing their specified BigFix Relay?

Technote (troubleshooting)


Problem(Abstract)

Reasons why the BES Clients are not choosing a specified Relay.

Resolving the problem

During manual or automatic BigFix Relay selection the BigFix Clients will attempt to connect to the BigFix Relay at http://relayname:port/cgi-bin/bfenterprise/clientregister.exe?requesttype=version (8.2 and below) or http://relayname:port/cgi-bin/bfenterprise/clientregister.exe?RequestTypeRegisterMe60 (version 9 and above) . If they cannot make this connection, they cannot use the BigFix Relay.

There are a few common reasons why clients might not correctly find a relay:

  • The clients cannot resolve the DNS name of the relays - Many times with this type of issue, the BigFix Clients cannot resolve the DNS name of the BigFix Relay and therefore cannot use the BigFix Relay. The BigFix Relay reports its DNS name to the BigFix Server and that list is distributed to the BigFix Clients. You can see the DNS name of the BigFix Relay by looking at the "DNS Name" in the BigFix Console (right click on the column headings if you cannot see this property).
    If the DNS name of the BigFix Relay is unresolvable by the BigFix Clients because the DNS name is not fully qualified or because of another DNS issue, you can override the BigFix Relay's DNS name by changing the "_BESClient_Relay_NameOverride" setting on the BigFix Relay computer to return a different DNS name or an IP address. More information on how to do this is available at:
    BigFix Configuration Settings..
  • The BES Clients are not set to use a BigFix Relay - By default, the BigFix Clients will connect to the main BES Server. You will need to either manually point the BigFix Clients at a BigFix Relay or set the BES Clients to automatically find their closest BES Relay. More information on how to do this is available in the BES Administrators Guide at:
    BES Administrators Guide.
  • A BES Client is blocked from contacting the BES Relay because of a firewall or NAT - The BES Client connects to the BES Relay using HTTP on the specified port number (default is 52311). Verify that the BES Client computer can make a connection to the BES Relay by going to the BES Client computer and pasting http://relayname:port/cgi-bin/bfenterprise/clientregister.exe?requesttype=version into a browser. If you see a version number, then the BES Client can properly connect to the BES Relay. If you receive an HTTP error, then you will need to determine why the BES Client cannot contact the BES Relay.
  • The BES Relay is not correctly installed - If the BES Relay is not correctly installed, the BES Clients won't be able to connect to it. You can attempt to connect to the BES Relay by pasting http://relayname:port/cgi-bin/bfenterprise/clientregister.exe?requesttype=version into a browser. If you do not see a version number returned in the browser, you should try to reinstall the BES Relay to see if that fixes the problem.
  • ICMP is blocked between BES Clients and BES Relays and the BES Clients are using automatic relay selection - The BES Clients use ICMP to determine how many network hops are between the BES Client and the BES Relay. If ICMP is blocked, the BES Clients will not be able to figure out their best BES Relay and they will randomly choose a BES Relay to use. Ping the BES Relay from the BES Client computer to see if ICMP is blocked.
