Need help installing ustreamer

luckyflyer

@gtj0 Thanks for your help and sorry to be such a pain.
I enter each command and this is what I get.

pi@duet3:~ $ sudo mv /etc/udev/rules.d/80-ustreamer.rules /root/
pi@duet3:~ $ sudo systemctl daemon-reload
pi@duet3:~ $ sudo systemctl enable ustreamer@video0
Failed to enable unit: Unit file ustreamer@video0.service does not exist.

I have followed the previous steps exactly and several times using copy and paste. I'm using nano3.2 and do ctrl X Yes then enter to save and then reboot. I do this for both of the files. I'm at a loss to for why the service does not exist.

One thing I've noticed is when I go back into the editor the text that I previously entered

ACTION=="add", KERNEL=="video0", SUBSYSTEM=="video4linux", TAG+="systemd", ENV{SYSTEMD_WANTS}+="ustreamer@%k.service"
ACTION=="remove", KERNEL=="video0", SUBSYSTEM=="video4linux", RUN+="/bin/systemctl --no-block stop ustreamer@%k.service"

and

[Unit]
Description=UStreamer for %I
[Service]
Type=simple
ExecStart=/usr/local/bin/ustreamer --exit-on-parent-death -r 640x480 --static /tmp/ -d /dev/%i --host=0.0.0.0 --port=8080
[Install]
WantedBy=multi-user.target

are still there, is this normal? I have the feeling that the files are not being saved. I'm wondering if I don't have permissions set correctly but get no error stating that I don't. Doing research to understand about permissions.

@luckyflyer Are you sure the ustreamer@.service file is located in /etc/systemd/system and that it's named exactly that?

Try ls -al /etc/systemd/system then cat /etc/systemd/system/ustreamer@.service

pi@duet3:~ $ cat /etc/systemd/system/ustreamer@.service
cat: /etc/systemd/system/ustreamer@.service: No such file or directory

Looks like the first one is there, but not the second.
I think it's something with my editor but don't know how to check to see.

@luckyflyer maybe try making it executable?

sudo chmod +x /etc/systemd/system/ustreamer@.service

(long shot)

luckyflyer

tried it,

pi@duet3:~ $ sudo chmod +x /etc/systemd/system/ustreamer@.service
chmod: cannot access '/etc/systemd/system/ustreamer@.service': No such file or directory

@gtj0 @bearer
Been reading up on the cat command, was wondering if that would be a good way to create and save the missing file?

A Former User

hmm, does the filename have a : at the end?

sudo mv /etc/systemd/system/ustreamer@.service: /etc/systemd/system/ustreamer@.service
sudo chmod +x /etc/systemd/system/ustreamer@.service

I noticed that in

ls -al /etc/systemd/system

that in line 29 it is

ustreamer@.service:

With a colon, instead of

ustreamer@.service

Is this a problem?

luckyflyer

They say great minds think alike................ maybe, I don't know lol.

well, you can use cat and heredoc to create files like so

cat << EOF > /tmp/yourfilehere
These contents will be written to the file.
        This line is indented.
EOF

but redirects and sudo gets messy so you'd need something like

cat << EOF | sudo tee /tmp/yourfilehere
These contents will be written to the file.
        This line is indented.
EOF

but you'll have to deal with escaping on the command line etc. i to use it from time to time, but its not always the best option.

sudo mv renames it

sudo mv /etc/systemd/system/ustreamer@.service: /etc/systemd/system/ustreamer@.service
sudo chmod +x /etc/systemd/system/ustreamer@.service

edit thats better.

@luckyflyer thats the same, its two commands, forum made it one line when i made it a quote. look for one that is two lines, i'm not gonna quote it again just to have the forum mess it up again
