#9453 — minissdpd, why?

Hi,

I've been running a Pi with Raspbian & an external USB drive as a sort
of home server for about 2 months.  In the past 2 or 3 days only, & in
short bursts, minissdpd has started putting stuff in the syslog like

24 devices removed (good-bye!)

device not found for removing : uuid:[...]:urn:[...]
(repeated many times with some repetition & variation in the [...]
bits)

16 new devices added


There doesn't seem to be much information on the WWW about this
service or what I would want to use it for.  Should I just disable the
daemon in '/etc/defaults/minissdpd', or remove the package?  What do
the messages tell me about stuff happening on my LAN?  Why have they
only just started appearing?

Thanks.

$ aptitude show minissdpd

 MiniSSDPd is a small daemon used by MiniUPnPc (a UPnP control point
 for IGD devices) to speed up device discoveries. MiniSSDPd keeps
 memory of all UPnP devices that announced themselves on the network
 through SSDP NOTIFY packets. MiniSSDPd also has the ability to handle
 all SSDP traffic received on a computer via the multicast group
 239.255.255.250:1900.

So are you using UPnP? If not, you might as well purge that and
miniupnpc, libminiupnpc8, python-miniupnpc, etc.

AFAICT, I'm not using UPnP, but I'm now wondering what all these
things are that it keeps discovering.

There are lots of things that you better remove when you want a
deterministic system, like "ifplugd", "avahi-daemon", "minissdpd" and
probably even more.  Those gadget are written by the people who want
to convert Linux into Windows, including the unreliability.

Is the Pi visible to the Internet?

Just asking because I recently read of vulnerabilities in some routers 
which were being exploited via SSDP.

Not the one I read, but it does mention DDoS and the SSDP protocol.

No.
