Thanks a lot both of you !
About GNu and stuff, you may be found this quite strange but the exploitation system of my school is ... OpenVMS !
At some point we're going to use unix , but at for almost two year we only work on VMS (wich is quite a good system by the way)...
I erased the error_log and it's still going wrong !
[Belaran:/etc/httpd/users] belaran% ls
belaran.conf error_log
[Belaran:/etc/httpd/users] belaran% sudo rm error_log
[Belaran:/etc/httpd/users] belaran% ls
belaran.conf
[Belaran:/etc/httpd/users] belaran% apachectl graceful
/usr/sbin/apachectl graceful: httpd not running, trying to start
Processing config directory: /private/etc/httpd/users
Processing config file: /private/etc/httpd/users/belaran.conf
fopen: Permission denied
httpd: could not open error log file /private/var/log/httpd/error_log.
/usr/sbin/apachectl graceful: httpd could not be started
[Belaran:/etc/httpd/users] belaran%
Obviously there somekind of authorisation problem. I checked the rights with the bacthmod 1.31 freeware and i got this
owner (belaran): R W
Groupe (staff) : R
World : R
why is it unable to open it ? Everybody can !!!
