that seems to be ok, if the noexec flag was enabled on the partition where /var is stored that'd be the reason why it fails, but it isn't in your case. Can you strace your sudo call?

I looked at the error log and saw /home instead of /var. If you didn't mention it, I wouldn't notice...

strace givesme a lotof output...I don't really know what you want to see exactly, so i'll post some from the end (before what is pasted below, there are a lot of lines with bad file descriptor).
here it goes:

It seems that neither /home nor /var is a separate partition...

blunt · 01-07-2008 05:14 AM

no they are not in separate partitions..is that a problem?

blunt Wrote:no they are not in separate partitions..is that a problem?

nono, I just wanted to clear the thing with /var and /home

blunt · 01-09-2008 05:18 AM

anyone can figure what's the problem by the strace output?

or anyone which had the same problem and found a way to get around it?

please...I've tried installing ispcp about ten times, from different nightly builds, and always get the same problem...

And I really need it working, so any hint is appreciated...

the server is a vps created with openvz, and is a debian 4.0 distribution.

raphael · 01-09-2008 09:03 AM

do you have any security tool around?
does
# usermod -s vu2000
help?
what is the output of grep ^vu2000 /etc/passwd?
by the way, I don't think you used
strace -u vu2000 /var/www/fcgi/master/php5-fcgi-starter
to get a strace, did you? it's output would be cleaner than using strace sudo -u /...
Anyway please try using strace -u vu2000, the first line of its output should be execve("/var/www/....

blunt · 01-09-2008 08:39 PM

Here is the output of strace:

ispcp:~# strace -u vu2000 /var/www/fcgi/master/php5-fcgi-starter

and the contents of /etc/passwd

ispcp:~# grep ^vu2000 /etc/passwd
vu2000:x:2000:2000:vu-master:/var/www/fcgi/master:/bin/false

usermod -s vu2000
shows me the help for usermod...don't know why...

does this clear anything up?

thank you

raphael · 01-10-2008 09:31 AM

what about:
usermod -s /bin/sh vu2000
lsattr /var/www/fcgi/master/php5-fcgi-starter

blunt · 01-10-2008 08:37 PM

ispcp:~# usermod -s /bin/sh vu2000
ispcp:~# lsattr /var/www/fcgi/master/php5-fcgi-starter
------------------ /var/www/fcgi/master/php5-fcgi-starter

and here is something else:
ispcp:~# ls -la /var/www/fcgi/master/php5-fcgi-starter
-rwxr-xr-x 1 vu2000 vu2000 195 Jan 8 13:36 /var/www/fcgi/master/php5-fcgi-starter

I really don't understand the problem, since vu2000 is the owner of the file...
thanks for your help.
