sorry there was a typo, fixed it in the original message
mv /etc/e-smith/templates-custom/etc/httpd/conf/httpd.conf /root/
should be
mv /etc/e-smith/templates-custom/etc/httpd.conf/httpd.conf /root/
as shown in your pic "aucun fichier ou dossier" because of the typo, so nothing has changed
a free tips, when typing this long paths, hit "tab" key it will autocomplete to what is available, it limits the amount of typos, and could have help you to find mine
but funny, you do not seem to have any templates custom looking at the empty output of
/sbin/e-smith/audittools/templates
so might not be this the issue...
could you give us the output of
tail -f /var/log/httpd/error_log
also the output of
tail -f /var/log/dhcpd/dhcpd.log -n50
