IPDADM(1M)IPDADM(1M)NAMEipdadm - administer the Internet packet disturber
SYNOPSISipdadm [-z zonename] subcommand [subcommand-options]
DESCRIPTION
The ipdadm utility is used to administer the illumos facility for simu‐
lating pathological networks by induce packet drops, delays, and cor‐
ruption.
This functionality is only able to the global zone and zones with
exclusive networking stacks. If this is enabled for the global zone,
any zone with a shared networking stack will be affected.
OPTIONS
The following options are supported:
-z
The string of the zonename to control. If this is not specified,
the current zone is used. For the list subcommand, this option is
not supported.
SUBCOMMANDS
The following subcommands are supported:
corrupt percent
Sets the chance for packets to be corrupted to percent which must
be an integer between 0 and 100. Setting percent to 0 disables
packet corruption and is equivalent to calling remove corrupt. When
enabled, a random byte will have a single bit flipped.
delay microseconds
Inserts microseconds of delay between both the transmit and receive
of each packet. Setting microseconds to zero is equivalent to call‐
ing remove delay.
drop percent
Sets the chance for packets to be dropped to percent. percent must
be an integer between 0 and 100. Setting percent to zero is equiva‐
lent to calling remove drop.
info
Prints the current values for packet corruption, packet dropping,
and packet delay for the zone.
list
Prints out the zonename of each zone that has active (non-zero)
packet corruption, packet delay, and packet drop.
remove corrupt,delay,drop
Disables the requested forms of packet perturbation for the zone.
This is functionally equivalent to setting the value to zero. One
or more of corrupt, delay, and drop can be specified as a comma
separated list.
EXAMPLES
Example 1 Viewing zone information
The following command illustrates how to obtain information about a
specific zone while in the global zone.
# ipdadm-z 949860c5-52e2-4f32-965d-02e60e116b72 info
ipd information for zone 949860c5-52e2-4f32-965d-02e60e116b72:
corrupt: 0% chance of packet corruption
drop: 0% chance of packet drop
delay: 0 microsecond delay per packet
Example 2 Removing multiple perturbations
The following command illustrates the use of the remove subcommand from
inside of a zone.
# ipdadm remove corrupt,drop
Example 3 Enabling packet drops
The following command illustrates the use of the drop subcommand from
the global zone.
# ipdadm-z 949860c5-52e2-4f32-965d-02e60e116b72 drop 25
EXIT STATUS
The following exit values are returned:
0
Successful completion.
1
An error occurred.
2
Invalid command line options or arguments were specified.
