lsof gives "Execute permision denied" on AIX4330-11

Hi all,

lsof gives "Execute permision denied" on AIX4330-11.

# ls -alF /usr/bin/lsof
-rwx------ 1 root system 612041 Apr 13 07:25 /usr/bin/lsof*

Any idea please?

Thanks!

Hi there,

I assume you're trying to execute the command as root user ?! ;-)

Try to check whether there's another lsof file somewhere on the machine using

find / -name lsof

Maybe there is a second file with that name having different permissions ...

Or try this:

whence lsof && ls -l $(whence lsof)

You should be able to find out which file named "lsof" the shell is trying to start...

Yep...as root...

# whoami
root
# whence lsof && ls -l $(whence lsof)
/usr/bin/lsof
-rwx------ 1 root system 612041 Apr 13 07:25 /usr/bin/lsof
#

That's a pretty big executable for lsof. How did you install it?

Also, what does "file /usr/bin/lsof" show?

Hi,

maybe there is my problem:

# file /usr/bin/lsof
/usr/bin/lsof: data or International Language text

It gives this message, although it is a binary. The same lsof (same size, etc) works fine on a 5.3 system.
I do not know how lsof was installed on this system. Maybe just ftp'ed.

So this one will not work. Will have to install from scratch.

Thanks a lot for your help.!
Michael

An executable from a 5.3 machine won't always run on a 4.3.3 machine. Especially lsof needs to be a specific version for a specific AIX kernel version because of the changes in kernel table layouts between the different AIX versions.

Other than that it might have been ftpd over in ascii mode which would mess up the structure of an executable file anyhow.

I advise you to download/isntall an lsof version specific for AIX 4.3.3 (and 4330-11 at that)


HTH,
