systemctl

This is likely old hat for most and likely done "in the dumbest way possible", but in case anyone else wants to run fishnet under systemctl, here's what I did on CentOS Stream:

Moved fishnet-x86_64-unknown-linux-gnu executable to /usr/local/bin
Moved fishnet.ini to /etc

Created /usr/local/bin/fishnet.sh:

#!/bin/bash
/usr/local/bin/fishnet-x86_64-unknown-linux-gnu --conf /etc/fishnet.ini

Created /etc/systemd/system/fishnet.service:

# Executable binary goes in /usr/local/bin
# fishnet.ini goes in /etc/fishnet.ini
[Unit]
Description=Lichess.org fishnet client
[Service]
User=<user you want to use>
WorkingDirectory=/usr/local/bin
ExecStart=/usr/local/bin/fishnet.sh
Restart=always
[Install]
WantedBy=multi-user.target

After that, I enabled the service:

systemctl enable --now fishnet.service
systemctl start fishnet
systemctl status fishnet

If you want to look at the log:
sudo tail -f /var/log/messages

Thanks for sharing. Run

/usr/local/bin/fishnet-x86_64-unknown-linux-gnu --conf /etc/fishnet.ini systemd

to generate an even better service file. No helper script like fishnet.sh should be required.

Possibly slightly due to the Nice=5, if your server is doing other work. Other than that, no difference is expected.

Ok. Aside from normal user interaction (cockpit, ssh, etc), nothing else is running on this system.

Hi there,
I know this is somewhat necromancing the thread - two quick questions: "User you want to use", is that the local machine user? And secondly, where would one put the private key to use?
Thanks in advance, xDSx

(I am looking to adapt this solution to launchctl on macOS, as I would like to run it in the background on a work machine where I am not in all the time)

As defense in depth, it could also be a new user that doesn't have any privileges.

The private key can be in a fishnet.ini referenced using --conf /path/to/fishnet.ini:

[Fishnet]
key = ***

There's also --key ***, but note that the key might then appear in the process list.

thanks for the quick response, I will try to implement this soon! (I'm new to launchctl and their plist sytsem)
