-bash: /dev/null: Permission denied woes

grassushi · n00b Joined: 11 Feb 2005 Posts: 54

I updated my system today via "emerge -u world" and since I rebooted, everytime I try to login I get:

"-bash: /dev/null: Permission denied."

Changing the permissions to "o+rw /dev/null" fixes the problem, until I reboot. Then it is back to the above error.

Does anyone know what package is broken that is causing this strange error, and how I might permanently resolve this issue rather than having to change the permissions of /dev/null everytime I reboot?

Thanks in advance.

You could be lazy and add the chmod command to /etc/conf.d/local.start

Or you could undergo the (admitedly immense) strain of searching the forum for people who have already solved your problem: https://forums.gentoo.org/viewtopic-t-316544-highlight-udev+dev+null.html

Thank you Gherald for the link. I did search teh forum, but didn't find anything that worked on a permanent basis. Apparently I have yet to master the art of forum searching.

That link *mostly* fixes the problem. I don't get the /dev/null error anymore, but now my aterm/xterm terminals won't open from the fluxbox menu.

Any ideas?

did xterm, aterm work using the manual chmod command?

No, unfortunately they didn't.

Seperate problem then (although might still be udev related).

Is it just the fluxbox menu that can't start terms? i.e. can you open terms some other way?

I tried using "fbrun" to execute the terminals, still to no avail.

Does the console from which you started X show anything? How about /var/log/Xorg.0.log ?

The console from which I started x shows nothing revealing, but the Xorg.0.log does.

Pardon the gigantic size of this next snip, but its the best way to explain:

i too am getting this error. I believe it is a udev problem but i have no idea on how to fix this. I am really confused right bow because nothing except what i put in fluxbox-auto start is working. I cannot seem to get even xmms up and running. So play anybody with any idea on how to fix this please respond asap... thanks.....

do you think downgading to the old udev will fix this prob?

Downgrading also fixed this problem for me.

I had it, but got it solved with the commands below:

emerge --unmerge udev
rm -r /etc/udev
emerge udev

this is definitely a udev problem -- i've just finished applying udev "upgrades" to my box, and now i'm getting hit with this error too.

udev in the x86 stable branch is now broken.

now this is wierd. i just "upgraded" my stable branch box to udev-056 and as soon as i ran dispatch-conf, i started having the permission errors at logon, such as the infamous "-bash: /dev/null: Permission denied."

interestingly, the problem appears to have disappeared after a reboot. (!)

I had the same problem as stated above with the permission denied with /dev/null

Rebooted, and unfortunatly still had the same problem...

When trying to run fluxbox... It boots fine, however none of the terminals show up when I try to run them...

Mozilla on the other hand works...

Currently I am downgrading from udev-056 to udev-045 to see if it will fix my problems...

LogicalGambit · n00b Joined: 02 Oct 2004 Posts: 12

Yup... that fixed my problem...

Anyone know what udev is used for?

We might want to say that udev is unstable in x86

I had the same issue when logging in. I had updated my system and forgot to run etc-update and update the config files that changed. Once I updated them, the problems was gone.

I don't get the error anymore. Seems to have fixed it.
