lsof

AIX

Compilation V4.87

Configure -clean aix
make
cd tests
make opt

Configuration (AIX 3.2, lsof 4.0)

Seems to work out-of-the-box.

Configuration (AIX >=4)

To allow ordinary users to use lsof on AIX, access to /dev/mem and /dev/kmem has to be enabled. This is accomplished by means of acl options.

Check if the group kmem exists (lsgroup kmem). If not, create it, either locally or on the appropriate NIS server.

Create (or use an already existing) file lsof.acl

base permissions
    owner(root):  r--
    group(system):  r--
    others:  ---
extended permissions
    enabled
    permit   r--     g:kmem
    permit   r--     g:kmem
    permit   r--     g:kmem

(Existing acl-options can be read out by aclget /dev/mem > lsof.acl )

Set the acl-options

aclput -i lsof.acl /dev/mem
aclput -i lsof.acl /dev/kmem

Modify the binary's permissions:
```
chgrp kmem lsof
chmod g+s  lsof
```

Note:

acl-options do not survive cloning (as of AIX 4.3).
Each AIX release/version might need its appropriate lsof version.

To allow all users to lsof, change the binary:

chgrp kmem lsof
chmod g+s  lsof

HP-UX

Compilation (V4.77)

Check if the kernel is prepared for debugging.

q4pxdb -s status /stand/vmunix
                               # or:
  pxdb -s status /stand/vmunix

If not prepared, do it now (caution, kernel will be written !):

cp -p /stand/vmunix /stand/vmunix.save # save old kernel
q4pxdb  /stand/vmunix
                      # or: 
  pxdb  /stand/vmunix

configure and compile
```
Configure hpuxgcc # for the gcc compiler
Configure hpux    # for the native compiler 
make
```
Note that I suspect /usr/include/sys/socketvar.h to be buggy on HP-UX 11.00, the line
```
extern struct sotimeq sotimeqhash[];
```
should obviously appear after definition of struct sotimeq

Configuration

If not yet existing, create group kmem (assume next free id is 202), insert in /etc/group
```
kmem:!:202:kmem   
```
To allow all users to lsof, change the binary:
```
chgrp kmem lsof
chmod g+s  lsof
```
