Install udev rules to permit non-root user from running srtn

[edaniszewski]

From the Osmocom website: (link in wiki)

In order to be able to use the dongle as a non-root user, you may install the appropriate udev rules file by calling cmake with -DINSTALL_UDEV_RULES=ON argument in the above build steps.

Currently, srtn can only be run as root or with sudo, see if changing installing udev rules will fix this.

with latest commit (above), user should only need to

$ sudo ./srtnmake

when building the software, and then be able to run

$ ./srtn

without having to use sudo anymore to run the program successfully.

Fix should be verified, then issue can be closed.

will this work with macos?

No, I don't believe it will. As I know it, udev rules are unique to linux and mac os doesn't have them.

I was planning on first having it compile and run successfully on Ubuntu, and then once stable, work on porting to other systems. I have yet to successfully build and run on mac os, #13 , but once proven that it can be done, an additional build script can be written for compiling on mac os, or to have a makefile, #4 , that will detect which architecture/OS is running and run the appropriate install and compile code from there.

ok good. in the worst case running via sudo on macos is probably a fine thing for the time being until we can find a proper way to make it runnable by all users.

17 , #18

will setuid be fine for this? if so, we can close as a dup of #10

[edaniszewski]

I'm not sure. I can try it out to see if that works though. In the README, it states:

4] In order to run as user 

a) FDI/USB make user member of dialout group
b) DAS-4020 copy over udev rules
c) install the udev rules file rtl-sdr.rules 

so based on part c.) it seems like they actually have to be installed, but this code hasn't been known to do things sensibly all the time..

I am going to test out setuid tomorrow and see if this is resolved. If not, it seems like the best place to install the udev rules would be in the makefile?

As far as I know, the udev rules will only work on Linux based OS, so if/when we get to porting it to other OSes, we can open new issues regarding this if we have to?

[acencini]

sounds good

It looks like, at least with the way I set up setuid, that this is no longer an issue. The program ran fine with no 40-rtl-sdr.rules file in /lib/udev/rules.d/, so once we go over my method for setuid to make sure its sound, I'd say this can be closed!

[acencini]

close it, Dr D
