Problem with some commands

Victor_138 — Tue, 17 May 2005 11:09:50 GMT

I'm having problems executing the man and more commands (at least). After issuing the command an Execute permission denied messege appers and the command quits.

Anyone knows what's going on? I'm trying the commands as root.

Hi,
You are having trouble with "more", try pg...
type which more
Should be something like:
# which more
/usr/bin/more
ant # ll /usr/bin/more
-r-xr-xr-x 2 bin bin 73728 Jul 16 2002 /usr/bin/more

All the best

Check the permissions on the more command - should be executable.

Also what user are you as? Again, more should be executable for all users.

Two other suggestions:

# type more

(this shows where the "more" command is located and configured or aliased) If it does not report: "more is /usr/bin/more" then you're not running the 'normal' more command.

ll -d / /usr /usr/bin

This verifies that someone (root) has not changed critical system directories. / should be 755 and /usr and /usr/bin should be 555. Hopefully, someone has not been reading the Unix Security for Dummys book and trying to 'improve' the system.

I'm logged in as root.

The ll /usr/bin/more returns this:
-r-xr-xr-x 2 bin bin

Re: Problem with some commands

Bill Hassell — Tue, 17 May 2005 12:17:30 GMT

Try the ll -d command above. It will list 3 directories like this:

l -d / /usr /usr/bin
drwxr-xr-x 25 root root 8192 May 13 14:53 //
dr-xr-xr-x 24 bin bin 8192 Feb 28 08:09 /usr/
dr-xr-xr-x 5 bin bin 16384 Mar 30 09:55 /usr/bin/

Your copy of more is probably OK but until you use the "type" command to determine exactly what happens when you type the command, that file may be irrelevant.

Hi,

may be the file is defective or compromized ? Or some setup of your shell environment may be missset

Check

ls -ld /usr/bin

Open an ftp client to your station and browse /usr/bin for a list of files.

Change the shell to a "csh" and check if this changes the error.

ll -d / /usr /usr/bin results:

drwxr-xr-x 29 root root 5120 May 17 07:45 /
dr-xr-xr-x 25 bin bin 1024 Apr 29 09:47 /usr
dr-xr-xr-x 6 bin bin 9216 Apr 1 19:09 /usr/bin

Volker, how can I change shells?

Re: Problem with some commands

Victor BERRIDGE — Tue, 17 May 2005 12:44:43 GMT

Hi
Since you are root I wonder we are not dealing with an nfs mountpoint...
type bdf and show us the output

All the best

OK no nfs
But / should /dev/vg00/lvol3 and not /dev/root..
You had some trouble at your last reboot

But I have to leave, having some proxy trouble to solve sorry...

What do you mean by "You had some trouble at your last reboot"?

Re: Problem with some commands

Bharat Katkar — Tue, 17 May 2005 15:10:12 GMT

hi,
i doubt if your shell has been corrupted.
do cksum on e.g. /usr/bin/bash if using bash.
try executing the command usinf different shell.

Hope that helps.
Regards,

/dev/root indicates that during the last reboot, there were some serious problems with the boot disk and the emergency devicefile /dev/root was used to get the system up and running. You can fix the /dev/root connection by:

rm /etc/mnttab
mount -a
bdf

However, you need to look at the boot information on your disk:

lvlnboot -v
vgdisplay vg00

This will tell you if there are problems. The fixes will depend on what errors you see.

Thanks Bill for explaining to our friend...

I noticed also /var is VERY full, and many processes open files /var or /tmp so I would suggest some cleaning up!
This might help (a little) or help eliminating reasons of issues...

P.S
Anyone else get the following?

The system is currently unavailable. Please try again later.

do cksum on e.g. /usr/bin/bash if using bash.

kcspecdp # cksum /usr/bin/sh
1175894443 495616 /usr/bin/sh

try executing the command using different shell.

kcspecdp # /usr/bin/ksh
kcspecdp # echo $SHELL
/sbin/sh
kcspecdp #

The shell doesn't seems to change.

Re: Problem with some commands

Victor BERRIDGE — Wed, 18 May 2005 11:28:01 GMT

ant:/export/f $ echo $SHELL
/usr/bin/ksh
ant:/export/f $ sh
ant:/export/f $ echo $SHELL
/usr/bin/ksh
ant:/export/f $

It doesnt show because the variable SHELL was set at login time...

All the best

Re: Problem with some commands

OK
Do a vgdisplay vg00
then a vgdisplay -v vg00
then vgdisplay -v vg00|grep dsk

Is there anywhere the word stale?
