[blunt]

Here is the output of strace:

ispcp:~# strace -u vu2000 /var/www/fcgi/master/php5-fcgi-starter
execve("/var/www/fcgi/master/php5-fcgi-starter", ["/var/www/fcgi/master/php5-fcgi-s"...], [/* 14 vars */]) = -1 EACCES (Permission denied)

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
