erratic
erratic is a plugin useful for testing client behavior. It returns a static response to all queries, but the responses can be delayed, dropped or truncated.
The erratic plugin will respond to every A or AAAA query. For any other type it will return a SERVFAIL response. The reply for A will return 192.0.2.53 (see RFC 5737), for AAAA it returns 2001:DB8::53 (see RFC 3849).
erratic can also be used in conjunction with the autopath plugin. This is mostly to aid in testing.
Syntax
erratic {
drop [AMOUNT]
truncate [AMOUNT]
delay [AMOUNT [DURATION]]
}
drop
: drop 1 per AMOUNT of queries, the default is 2.truncate
: truncate 1 per AMOUNT of queries, the default is 2.delay
: delay 1 per AMOUNT of queries for DURATION, the default for AMOUNT is 2 and the default for DURATION is 100ms.
Examples
. {
erratic {
drop 3
}
}
Or even shorter if the defaults suits you. Note this only drops queries, it does not delay them.
. {
erratic
}
Delay 1 in 3 queries for 50ms
. {
erratic {
delay 3 50ms
}
}
Delay 1 in 3 and truncate 1 in 5.
. {
erratic {
delay 3 5ms
truncate 5
}
}
Drop every second query.
. {
erratic {
drop 2
truncate 2
}
}
