Hi,
I'm not a Linux guru, so maybe my question is stupid, but are you sure
the command prints its output to the *standard* output?

hi Chris,
i found out that when execute ipkg, the return is before the header.
root [ /srv/www/test ]# /program/php-5.2.6/bin/php-cgi ipkg.php
ipkg version 0.99.163
X-Powered-By: PHP/5.2.6
Content-type: text/html
Array
(

which is different than the whoami program.
root [ /srv/www/test ]# /program/php-5.2.6/bin/php-cgi whoami.php
X-Powered-By: PHP/5.2.6
Content-type: text/html
the result of execwhoami is
root
can you see the different?

root [ /srv/www/test ]# su daemon
root [ /srv/www/test ]#
i didnt manage to switch user.
i will create an user... so that i can switch to it.
i created a user call lfs into group lfs.
able to execute ipkg-cl and /program/..../ipkg-ck --version.
then i change the httpd.conf to start apache with lfs and execute the
php
script to exec ipkg-cl --version.
basically it is not working.
root [ /srv/www/test ]# groupadd lfs
root [ /srv/www/test ]# useradd -s /bin/bash -g lfs -m -k /dev/null lfs
root [ /srv/www/test ]# passwd lfs

hi Chris,
my linux system is LFS that i build from scratch.
i cant su to daemon.
below is my /etc/passwd:
root [ /srv/www/test ]# cat /etc/passwd
root:x:0:0:root:/root:/bin/bash
nobody:x:99:99:Unprivileged User:/dev/null:/bin/false
sshd:x:50:50:sshd PrivSep:/var/lib/sshd:/bin/false
daemon:x:6:6:daemon:/dev/null:/bin/false
Change it, su, change it back. Looking at apache logs won't tell you
much
if you don't try something.
Are you running selinux?
<http://169.254.0.20>] /opt/ipkg-0.99.163/bin/ipkg-cl: Permission
denied, referer: http://169.254.0.101/test/
That one's pretty easy.

What about making an exec call, but piping the results of that call to a
text file. That way, it will be in a file that is easily accessed from
other parts of your site. I'm not sure which is more expensive, a call
to ifconfig, or a file read.
