20 | <para>Dropbear is a relatively small SSH 2 server and client. Dropbear has a small |
---|
21 | memory footprint suitable for memory-constrained environments, while still having |
---|
22 | the same features as OpenSSH. It does not depend on OpenSSL and it has a MIT |
---|
23 | style license. Optionally it can even be made smaller. |
