lsof problem --> /sbin/sh: lsof: Execute permission denied.

[Jack C. Mahaffey]

Just installed the 64-bit version of lsof after trying the 32 bit version.

Getting the following error:
/sbin/sh: lsof: Execute permission denied.

Here's my directory and file permissions:
# ll /usr/local/bin/lsof
-rwxr-sr-x 1 bin sys 252940 Jul 3 12:40 /usr/local/bin/lsof


# ll -d /usr/local/bin
drwxr-xr-x 6 bin bin 5120 Sep 17 14:32 /usr/local/bin

# ll -d /usr/local
drwxrwxrwx 16 bin bin 1024 Sep 17 13:42 /usr/local

# id root

#

# which lsof
/usr/local/bin/lsof
#

Any ideas?

Does this work:
# ./lsof /etc/services
or
# /usr/local/bin/lsof /etc/services

No, I tried this also.

First are you running lsof as root? Does it work then?
It should run as root regardless of the setting of the setuid and setgid bits.

Secondly my lsof executable is quite a bit smaller than yours (~156k) but I compiled from source so that may be fine.

[Cheryl Griffin]

Jack,
Where did you get the lsof from? I found another report of this error and it was a problem with how the 64 bit files were compiled. Downloading a clean copy fixed the problem.

You can download and compile it yourself or find one precompiled:

No, it does not run as root. I also attempted using a different login. Same problem.

Hi
Do you have any security software on your system that blocking you use of this.?
Try removing SGID bit, with plain 755 permission on lsof file.

Thanks.
Prashant.

I pulled the binary from perdue and got the following:

lsof_4.64: WARNING: compiled for HP-UX release B.11.11; this is B.11.00.
lsof_4.64: FATAL: pst_status_size should be: 1176; is 920

lsof_4.64: FATAL: pst_static doesn't contain pst_mpathnode_size
lsof_4.64: FATAL: pst_static doesn't contain pst_fileinfo2_size


Oh well. I'll go back and try changing the security to 755.

[Jack C. Mahaffey]

Changing permission to 755 didn't help.

Don't know if this is useful.
file lsof returns the following:

lsof: ELF-32 executable object file

Here's the ll listing again...

[Ted Ellis_2]

your operating system is 64 bit.. correct?

[A. Clay Stephenson]

Did you by any chance load the Itanium version rather than PA-RISC?

[Jack C. Mahaffey]

It is 64-bit

getconf KERNEL_BITS returns 64.

I pullled the lsof_4.64.gz version.

I'm an idiot when attempting to compile the source.

Here's what I got with the ./Configur hpuxgcc option:

[10064]root@chldevh:/tmp/lsof-4.64 # ./Configure hpuxgcc
Configuring /dev/kmem-based HP-UX lsof

Here's what I get with a normal compile, system doesn't have HP compiler:

Looking in /stand/vmunix for ipis_s with /usr/contrib/bin/q4 ...

!!!ERROR!!! /usr/contrib/bin/q4 failed and produced the following output.

!!!ERROR!!! !!!ERROR!!! !!!ERROR!!! !!!ERROR!!!
Configure can't use /usr/contrib/bin/q4 to examine the ipis_s
structure. You must do that yourself, report the result in
the HPUX_IPC_S_PATCH environment variable, then repeat the
Configure step. Consult the Configure script's use of
/usr/contrib/bin/q4 and the 00XCONFIG file for information
on ipis_s testing and the setting of HPUX_IPC_S_PATCH.

I guess I need to find a 64-bit gcc compiler?

Hi Jack,

I have the same error before when I compile the lsof in 11i and used it by other user.

At last, I set the set-user-ID bit and all is OK, i.e. chmod u+s lsof

-rwsr-xr-x 1 root sys 159744 Mar 6 2002 /usr/local/bin/lsof

Regards,
Patrick

For those readers who might want the single chmod command for setting the security, the following command will work:
chmod 4555 lsof

Security will be set to -r-sr-xr-x
