What is xsp4.exe running on a new PiHubG3?

[kenm]

sudo ps -eaf |grep xsp4

/usr/bin/mono /usr/lib/mono/4.5/xsp4.exe --port 8084 --address 0.0.0.0 --appconfigdir /etc/xsp4 --nonstop

You can safely turn this off . This is just a server not related to HomeSeer.

https://manpages.ubuntu.com/manpages...an1/xsp.1.html

sudo systemctl stop mono-xsp4.service && sudo systemctl disable mono-xsp4.service

OK. Not related to HomeSeer. So the next question is "Why is it running on a PiHubG3?".

This is installed with mono-complete package. Apparently supports serving of mono documentation. Not used by HS applications.

mono-complete includes the mono-devel package needed to run HS applications, plus more:

pi@HS4Pro:~ $apt-cache depends mono-complete
mono-complete
Depends: mono-runtime
Depends: mono-runtime-sgen
Depends: libmono-2.0-1
Depends: libmono-profiler
Depends: mono-utils
Depends: mono-devel
Depends: mono-mcs
Depends: mono-roslyn
Depends: mono-csharp-shell
Depends: mono-4.0-gac
Depends: mono-4.0-service
Depends: monodoc-base
Depends: monodoc-manual
Depends: libmono-cil-dev
Depends: referenceassemblies-pcl
Depends: msbuild
Depends: ca-certificates-mono
Suggests: mono-llvm-support

You can determine what package installed the xsp4.exe file via

dpkg -S /usr/bin/mono /usr/lib/mono/4.5/xsp4.exe

IIRC, it's mono-xsp4

You can run up the dependency tree to determine what cause a particular package to be installed

pi@HS4Pro:~ $apt-cache rdepends mono-xsp4
mono-xsp4
Reverse Depends:
mono-xsp
|monodoc-http
mono-xsp
|asp.net-examples
|monodoc-http
|asp.net-examples
pi@HS4Pro:~ $ apt-cache rdepends monodoc-http
monodoc-http
Reverse Depends:
|monodoc-manual
|monodoc-manual
pi@HS4Pro:~ $ apt-cache rdepends monodoc-manual
monodoc-manual
Reverse Depends:
mono-complete
....

Note that mono-devel doesn't install mono-xsp4.

You can uninstall mono-xsp4 via

sudo apt remove mono-xsp4

reinstall via

sudo apt install mono-xsp4

Thanks guys. TBH, I don't think that's what's causing the problem but I wanted to know for sure what that was. I'm trying to help another user who can't connect to his PiHubG3 after a power outage. ps -eaf |grep mono confirms that HSConsole,exe is not running. further confirmed by netstat -tulpn |grep :80. The hub is connected directly to his router and the router takes several minutes to boot after the power outage. The hub is now set to a static IP in /etc/dhcpcd.conf (not just a DHCP reservation) but that still hasn't resolved the problem.

xsp4.exe is one of the things running on his PiHubG3 that isn't running on my Pi400 running HS4PiV5.

I saw that thread. I'll bet the culprit is the application startup method. Past HS Pi offerings started the HSConsole app from /etc/rc.local, a throwback to the 1990's. Better to use systemd.

I just confirmed that when my HS4Pro rpi system is rebooted with no network attached, the homeseer service doesn't start. Once reattached, the service starts as normal and all is good.
