Hello all, I have been making fun experimenting with ham/rtl-sdr package in raspberry pi 4 on NetBSD. After some failures trying to get it work as a normal user instead of root, I came to the conclusion that I should change the permissions of these two files in /dev/ugen to be used by the "wheel" group I belong to.
original files permission: crw------- 1 root wheel 72, 0 Jun 30 19:58 ugen0.00 crw------- 1 root wheel 72, 1 Jun 30 19:58 ugen0.01 files after permissions change: crw-rw---- 1 root wheel 72, 0 Jun 30 19:58 ugen0.00 crw-rw---- 1 root wheel 72, 1 Jun 30 19:58 ugen0.01 That works fine to make the receiver work as wheel group user.. Before knowing that those two files were the right ones, I was desperately tweaking /dev/usb* files. Receiver started to work as normal user. Then I removed the permisions to usb files expecting the receiver stop working as normal user, but the receiver continued to work. I was then puzzled. The only explanation for that is that I did a mistake and issued a "chmod 660 usb *" command in /dev/ instead "chmod 660 usb*" so the receiver started to work "brute force" ;-). So I believed that I screwed up all /dev/ permissions. I did a "sh MAKEDEV all" in /dev/ directory as read in a Install.html document on the NetBSD repositories but after a while I read that it should be done in single user mode. I followed the procedure " 22.7. How to rebuild the devices in /dev" in The NetBSD Guide to restore them using sh MAKEDEV all in single user mode. I think that they were restored fine :-) Manual file permissions change on /dev/ugen files worked flawlessly. But my concern is if that should be configured somewhere else (something like udev rules in linux) or I did it right. Because I rebooted the system there was nothing at sh shell history, I would be a good thing being able to know what I did. I think that NetBSD sh does not have the posibility of configuring a history file to record the past commands, but not sure. Am I right? That would be a good thing. Thanks so much in advance. Ramiro.
