bash:/dev/null: Permission denied ubuntu Jaunty

[unixbhaskar]

Hi

I have tired these method below:

1) Remove/Create /dev/null

2) Set permission 0666

3) Put an entry in /etc/rc.local

4) create a file in /etc/udev/rules.d as 40-persistent.rules and put kernel=null and permission="0666"

Still it's not able to get me in through graphical login screen.If I login via terminal , then get that error: bash:/dev/null/ : Permission denied.

Although I have encountered the same problem few months back and I fixed it by putting and entry in rc.local and it come back.

But this time it not working .... please help

Any help would be greatly appreciated. I have seen the other thread ahd closed reagrding this problem. So created a new one with old problem.

Thanks

This should not have been a problem if Ubuntu got properly installed. /dev/null is a pseudo device that is automatically created when the system boots - basically it is the bit-bucket. The system also creates a similar file /dev/zero which if read returns 0 bytes, usefull for zero-filling files and/or an entire drive that needs a "low-level" format. You should never try to create/remove/modify these devices or their ID's.

So, if you cannot login or get the system started properly, then it is fubar and probably needs to be reinstalled from scratch.

Thanx for your suggestion ,but it is useless. Because, iff I have to reinstalled the OS again ,then I wouldn't have asked the question here. Please read my post carefully then reply.

I have mentioned that fix this issue previously, and this time it won;t working. Might be some extra step needed.

Reinstalling the OS is last resort man.

Anyway thanks for your thoughts.
