HDHomeRun DVR executable

TrueNAS General

I’m trying to migrate from Core to Scale

On Core I had HDHomeRun DVR from Silicon Dust site - it’s a single file executable

There is a Linux version

But when I try to run it I get a permission denied error (even as root via sudo su)

tmux → ./hdhomerun_record_linux: 9: /tmp/hdhomerun_record_x64: Permission denied

tried /home/admin still no luck

I really don’t want (or have the energy) to learn docker/kubernetes etc for a single file executable - I might just use a VM

Novice linux-user here, but after downloading you flagged it as executable, right? :thinking:

sudo chmod +x already done

ls -l
-rwxr-xr-x 1 admin admin 1645822 Sep 2 17:36 hdhomerun_record_linux

./hdhomerun_record_linux: 9: /tmp/hdhomerun_record_x64: Permission denied

Oh, eww, it’s some kind of hacky self-extractor.

It smacks it into the /tmp directory, cp it out back to your expected directory, chmod the real binary again, and it should work:

ZFS datasets can have their execute permissions removed for security reasons;

> zfs get exec rpool/home
NAME        PROPERTY  VALUE  SOURCE
rpool/home  exec      on     default

This is from my home desktop, not TrueNAS.

Does the dataset where the file is located, have “exec” permissions “on”?


Their are other dataset attributes, more are being added. But the “exec” on probably existed for at least 10 or 15 years.

Yeah in this case it’s because the “app” is trying to re-launch after extracting to /tmp, but agreed this should be kept in mind. I think they’ll be fine since the wrapper script was provably executable from the desired location, just that by relaunching from a different place it no longer had execution perms for is the problem.

thanks

I’m not that familiar with *Nix and I’ve not come across this before!

I’m going to contact the maker and let them know for future releases (especially for scale - core just worked)
