Summary: Required SAIG TDClient Initialization File Replacement

Posted on 02-01-2008

The U.S. Department of Education is pleased to announce the availability of a new initialization file (tdclient.ini) to be used with all versions of the Transaction Delivery (TD) Client and Easy Access (EA) Client mainframe and midrange transmission software. An updated SAIG Host Communication Guide will also be available. This information will be available on the Federal Student Aid Download (FSAdownload) Web site, located at, by January 31, 2008.

We are in the process of relocating the data center that supports numerous Federal Student Aid systems and Web sites. This change will require a new IP address for SAIG Mailbox transmissions. Due to a change in the IP address that resides within the TDClient initialization file, all mainframe and midrange users of TDClient must replace the old initialization file. We highly recommend that you complete this upgrade by May 1, 2008. If you fail to upgrade by the time the transition to the new data center is complete you will be unable to send and receive files.

The tdclient.ini file is available in two formats; EBCDIC and ASCII, and will be available on the FSAdownload Web site ( Supported TDClient platforms are MVS/ZOS, HPUX, AIX, OS400 and Sun Solaris. See the SAIG Host Communication Guide, which is also available on the FSAdownload Web site, for detailed installation information.

Firewalls that have been modified to allow TDClient to communicate using the fixed IP address utilized by previous versions of the TDClient initialization file will need to be updated to use the URL "" instead. The port TDClient uses, port 26581, has not changed.
