I don't see any harm in trying it but I wouldn't expect it to work.

Many licence managers rely on you not being able to change the MAC address on an adapter and, indeed, many network interfaces are built onto the motherboard so tying the application to the machine.

Do you know the name of the licence manager software (if there is one) or does the app simply read the MAC address of the system it's on?

Changing MAC address of a NIC

All, I have a need to software change the MAC address of a NIC in a Sparc Ultra 10 - I believe there is a command that allows to do this at boot up? Is it a missing (to me) part of ifconfig ? If so, what is the syntax? All replies gratefully received ! Thanks Andrew (3 Replies)

SHOREWALL-MACLIST(5)						  [FIXME: manual]					      SHOREWALL-MACLIST(5)

NAME
maclist - Shorewall MAC Verification file SYNOPSIS
/etc/shorewall/maclist DESCRIPTION
This file is used to define the MAC addresses and optionally their associated IP addresses to be allowed to use the specified interface. The feature is enabled by using the maclist option in the shorewall-interfaces[1](5) or shorewall-hosts[2](5) configuration file. The columns in the file are as follows (where the column name is followed by a different name in parentheses, the different name is used in the alternate specification syntax). DISPOSITION - {ACCEPT|DROP|REJECT}[:log-level] ACCEPT or DROP (if MACLIST_TABLE=filter in shorewall.conf[3](5), then REJECT is also allowed). If specified, the log-level causes packets matching the rule to be logged at that level. INTERFACE - interface Network interface to a host. MAC - address MAC address of the host -- you do not need to use the Shorewall format for MAC addresses here. If IP ADDRESSESES is supplied then MAC can be supplied as a dash (-) IP ADDRESSES (addresses) - [address[,address]...] Optional - if specified, both the MAC and IP address must match. This column can contain a comma-separated list of host and/or subnet addresses. If your kernel and iptables have iprange match support then IP address ranges are also allowed. Similarly, if your kernel and iptables include ipset support than set names (prefixed by "+") are also allowed. FILES
