Ok, here you are - as a normal user (non root) inside the jail, I have run: $ dd if=/dev/random of=/dev/stdout bs=512 count=1 | hexdump -C dd: /dev/stdout: Permission denied $ ls -asl /dev/stdout 0 crw--- 1 root wheel 22, 1 Sep 3 21:46 /dev/stdout All of this was _after_ I ran the `

related jail topic - /dev/null often and regularly reverts permissions...

If you run a jail, and inside that jail is a /dev with the file /dev/null in it, the normal 0666 permissions of /dev/null will often get changed to 0600. I cannot see any reason why this would happen - I thought maybe there was something in /etc/rc that would do it, but there is not. Further,

Re: related jail topic - /dev/null often and regularly reverts permissions...

Well, what I am seeing is the /dev/null changing permissions _after_ the build/installation of the jail. That is, either it is changing at some random time while the jail is running, or it changes after the jail is stopped, then started again. And it happens over and over, that is, if I reset

Ok, I am not sure how I can do that though - I cannot successfully run `rndcontrol -s X` inside a jail. On the other hand, I already have: rand_irqs="9 10 11 13 14" In my rc.conf on the underlying host machine, and have done several boots with that in place. So presumably I should be seeded
