# kcli trace-smtp-server
|
|
|
|
|
|
Trace incoming connections made to the SMTP service.
|
|
|
|
This is a diagnostic tool for the server operator.
|
|
|
|
Connections are logged in real time.
|
|
|
|
Take care to use an appropriate `--source` when using this with a live busy server, as you will be overwhelmed by the traffic.
|
|
|
|
|
|
**Usage:** `kcli trace-smtp-server [OPTIONS]`
|
|
|
|
## Options
|
|
|
|
|
|
* `--source <SOURCE>` — Add a source (in CIDR format) to the list of source addresses that we want to filter by. If any are specified, then only connections made from a matching address will be traced. If no sources are specified, any/all incoming SMTP connections will be traced.
|
|
|
|
Can be used multiple times to add multiple candidate addresses.
|
|
|
|
Eg: --source 10.0.0.1 --source 192.168.1.0/24
|
|
|
|
* `--color <COLOR>` — Whether to colorize the output
|
|
|
|
Default value: `tty`
|
|
|
|
Possible values: `tty`, `yes`, `no`
|
|
|
|
|
|
* `--only-new` — Trace only newly opened sessions; ignore data from previously opened sessions
|
|
|
|
* `--only-one` — Trace the first session that we observe, ignoring all others
|
|
|
|
* `--terse` — Abbreviate especially the read side of the transaction trace, which is useful when examining high traffic and/or large message transmission
