I cannot finger the Annex from the FreeBSD v2.2.1. Finger works fine in a FreeBSD 2.1.7 and BSDI. Is this something that you experienced? Also can you give details of how you fix the problem? We have the FreeBSD 2.2.1 and the Annex on the same Ethernet cable. Does your configuration be the same? Or are you connecting to the Annex through a serial/modem connections? Your help is much appreciated.
