ssh login with normal user, receive: /dev/null: Permission denied
Hello All,
I have a dedicated server which was formerly running FreeBSD, but was recently replaced with RedHat 9 (Shrike) after a catastrophic hard drive failure. My ISP that hosts the box is pretty crappy, and would love to charge me about $100/hr to fix this problem, but it should be an easy fix with some guidance. Anyway, this is a fresh install and I have been the only one on the box so far. The problem is when I SSH in with a normal user account, this is what I am presented with: mark@'s password: -bash: /dev/null: Permission denied -bash: /dev/null: Permission denied -bash: /dev/null: Permission denied -bash: /dev/null: Permission denied -bash: /dev/null: Permission denied -bash: /dev/null: Permission denied [mark@]$ Also, after I view a file with 'less' I see: [mark@]$ less test /usr/bin/lesspipe.sh: line 50: /dev/null: Permission denied [mark@]$ When I log in with root, I don't get any of the /dev/null errors. Here is /dev/null: crw-r--r-- 1 root root 1, 3 Nov 11 18:46 /dev/null I just can't figure this one out. If anyone could offer a suggestion, it would be greatly appreciated. Thank you in advance, Mark |
Set permissions 666 on /dev/null. Non-root users lack writing permissions.

The basic answer is you don't have permissions to write to /dev/null :D
Not trying to be facetious - just that the message is telling you the problem. As root simply type "chmod 666 /dev/null". A subsequent "ls -l /dev/null" should show it now has "crw-rw-rw-" in the left most column. (For more details on the chmod command type "man chmod".) DETAILED RESPONSE FOLLOWS: Quote:
Of course what's got me wondering is why the hell its trying to access /dev/null in the first place. Maybe it always has and I just didn't realize it. Typically /dev/null is where you redirect unwanted output so it doesn't appear on your screen or in a log file. For example typing: 'ls -l >/dev/null" would send output to /dev/null so you'd never see it on the screen. Its common in background scripts such as init scripts or cron to redirect unwanted output as follows: myscript.sh >/dev/null 2>&1 The above says to send standard output (stdout a/k/a file descriptor 1) to /dev/null instead of the default (normally the terminal) then says to redirect standard error (stderr a/k/a file descriptor 2) to file descriptor 1 which has been redefined as /dev/null earlier on the line. P.S. RedHat 9 is rather old. Unless you have a specific need for it you might want to install the latest RedHat non-commercial Linux which is Fedora Core 4 (or at least Fedora Core 3 - the 2.6 kernel in 4 is still giving folks some issues but Fedora Core 3 is a lot later.) RedHat has split their commercial and non-commercial so that RedHat branded stuff (RedHat EL/AS) is commercial and Fedora is non-commercial |
Problem Solved -- Thanks!
