Bug ID: 172942
Summary: Libreoffice does not listen and respond to Multicast
Remote discovery over Wi-Fi
Product: Impress Remote
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: General
Assignee: [email protected]
Reporter: [email protected]
Description:
Impress Remote Android application tries to discover LibreOffice instances with
the Impress running by sending Multicast UDP packets to:
UDP Multicast dst address 239.0.0.1
dst port: 1598
UDP Payload: LOREMOTE_SEARCH
However on a "server" side (LO Impress on PC), the application does not listen
to these packets and does not respond to discovery attempts.
There's no UDP socket created by "soffice" binary.
I've run:
strace -fe trace=socket,recvfrom,sendto,bind,setsockopt,getsockopt soffice
test.odp
And there's no attempts to recvfrom, while I see the packets with Wireshark.
Overall, discovery is broken, either the protocol or port is not in sync with
Android application.
Steps to Reproduce:
1. Start Libreoffice Impress
2. Configure it to listen on Wi-Fi as described in
https://wiki.documentfoundation.org/Documentation/HowTo/Impress_Remote_(Android)
3. Start Android remote application
4. Switch to Wi-Fi tab
Actual Results:
The application never discovers the PC.
Expected Results:
The application discovers the LO Impress on PC and connects to it.
Reproducible: Always
User Profile Reset: No
Additional Info:
The application works if the IP address of the PC is entered manually,
bypassing auto-discovery.
