A lot of people appear to use the same MAC address.   The hash is� 469947894f9e298a7726b4a58ff7bf9f.    This has led to some bizarre effects, such as grid owners banning themselves via notecards passed around of 'known' griefers.�

Please don't ban it, as it is the hashed MAC address of the Windows Loopback adapter.� If you use ban lists for specific avatars, use the Disk ID0 instead.

Hundreds to thousands of Windows systems running Opensim servers have to use the Microsoft KM-TEST loopback driver when their router does not support loopback.  This adapter quite rudely has a constant Mac address of "02-00-4C-4F-4F-50" which is 469947894f9e298a7726b4a58ff7bf9f. � *� *

The other 'solution' for loopback, the etc/DNS hosts loopback hack, does not work as well as it causes issues where grid owners cannot teleport home.   Linux users of Opensim may have similar issues with etc/hosts.  Linux grid owners may also add a loopback adapter 'lo', or 'lo0' which is claimed to not have a MAC address, but you may not be safe from this bizarre ban bug. Linux MAC's appear as all zeros which would have a different hash from the above.

# ifconfig -a
1: lo: <LOOPBACK,UP,LOWER_UP> mtu 65536 qdisc noqueue state UNKNOWN group default qlen 1

    link/loopback 00:00:00:00:00:00 brd 00:00:00:00:00:00

If someone more knowledgeable could please check their logs for the hashed MAC for Linux Loopback, I would certainly appreciate it.   It should not be banned as a general rule, too.  I can add add a ban-ban for both to all DreamGrids.   Macs, while rarer, will have a similar issue.�
