|
|
|
|
> Read, write, redirect, and encrypt data across a network.
|
|
> An alternative implementation of a similar utility called `netcat`/`nc`.

|
|
- Listen for input on the specified port and write it to the specified file:
|
|
|
|
`ncat {{[-l|--listen]}} {{port}} > {{path/to/file}}`
|
|
|
|
- Accept multiple connections and keep ncat open after they have been closed:
|
|
|
|
`ncat {{[-lk|--listen --keep-open]}} {{port}}`
|
|
|
|
- Write output of specified file to the specified host on the specified port:
|
|
|
|
`ncat < {{path/to/file}} {{address}} {{port}}`
|
|
|
|
- Accept multiple incoming connections on an encrypted channel evading detection of traffic content:
|
|
|
|
`ncat --ssl {{[-k|--keep-open]}} {{[-l|--listen]}} {{port}}`
|
|
|
|
- Connect to an open `ncat` connection over SSL:
|
|
|
|
`ncat --ssl {{host}} {{port}}`
|
|
|
|
- Check connectivity to a remote host on a particular port with timeout:
|
|
|
|
`ncat {{[-w|--wait]}} {{seconds}} {{[-vz|--verbose -z]}} {{host}} {{port}}`
