Error in main loop KeyError: 'DisplayName'

[justinvreeland]

To be honest i'm not even sure that I'm using this correctly I wanted to discover the share on my network from my linux machine I started with wsdd -D -i wlp2s0 hoping it would just spit out a list of shares on my network but instead I the following error and it hangs forever. I'm using the aur package which is version 0.6.1

Thanks,

wsdd does not scan (if in discovery mode) for shares but for computers fulfilling the WSD protocol. Thus you will only see machines providing shares. Everything else is subject to Samba or whatever other client/protocol.

I the following error and it hangs forever.

Thanks for reporting that. Could you please try the issue-59 branch. There is (accidentally) a work-in-progress commit that should fix the problem. Currently it displays the device's UUID when using the socket-based API and the list command but that's cosmetic...

[justinvreeland]

Thanks for the response! Using that branch does eliminate that issue. However when using the verbose flag while I can see the hosts on my network, I have a new error.

Should I open a new ticket for that one.

Should I open a new ticket for that one.

No, thanks. As I said, the commit was WIP ;-)

Give the issue branch (see above) a try.
