IS_MULTICAST_ETHER_A(9) Network device support IS_MULTICAST_ETHER_A(9)NAME
is_multicast_ether_addr - Determine if the Ethernet address is a multicast.
SYNOPSIS
int is_multicast_ether_addr(const u8 * addr);
ARGUMENTS
addr
Pointer to a six-byte array containing the Ethernet address
DESCRIPTION
Return true if the address is a multicast address. By definition the broadcast address is also a multicast address.

mtest -- test multicast socket operations
SYNOPSIS
mtest
DESCRIPTION
The mtest utility is a small program for testing multicast socket operations.
It accepts the following commands, interactively, or as part of a scripted input file (useful for automated testing):
a ifname mac-addr Join the link-layer group address mac-addr on interface ifname. The group address should be in IEEE 802 MAC
format, delimited by colon (':') characters.
d ifname mac-addr Leave the link-layer group address mac-addr on interface ifname.
m ifname 1/0 Set or reset ALLMULTI mode on interface ifname. This option is deprecated and is now a no-op.
p ifname 1/0 Set or reset promiscuous mode on interface ifname.
j mcast-addr ifname [source-addr]
Join the multicast address mcast-addr on the interface with name ifname.
If an optional source source-addr is specified, a source-specific join will be performed; if mtest is already
joined to the multicast address, the source will be added to its filter list.
l mcast-addr ifname [source-addr]
Leave the multicast address mcast-addr on the interface with address ifname. If a source source-addr is
specified, only that source will be left.
i mcast-addr ifname n source-addr ...
Set the socket with membership of mcast-addr on interface ifname to include filter mode, and add n sources
beginning with source-addr to the inclusion filter list.
e mcast-addr ifname n source-addr ...
Set the socket with membership of mcast-addr on interface ifname to exclude filter mode, and add n sources
beginning with source-addr to the exclusion filter list.
t mcast-addr ifname source-addr
Set the socket with membership of mcast-addr on interface ifname to block traffic from source source-addr.
b mcast-addr ifname source-addr
Set the socket with membership of mcast-addr on interface ifname to allow traffic from source source-addr.
g mcast-addr ifname n Print n source filter entries for mcast-addr on interface ifname.
f filename Read commands from the file filename.
s n Sleep for n seconds.
? List legal commands.
q Quit the program.
IMPLEMENTATION NOTES
For each command implemented by mtest, the address family of each argument must be identical; it is not possible to mix IPv4 multicast mem-
berships with IPv6, for example.
To support IPv6, all commands have now changed to accept an interface name rather than an interface address. For IPv4, the program will per-
form a lookup of the primary IP address based on the interface name. This may fail if no primary IP address is assigned.

Hi all,
I want to create a new user and grant him ONLY transfer files access to a specific directory where he can only upload and read the files. He should be restricted to this activity only.
