Hi,
I just upgraded my server from Debian 7 to Debian 8. Everything seemed to go fine. However, Apache doesn't seem to be able to see the web files. If I go to my server's IP, I get an empty directory listing, as if the document root was pointed to an empty directory. However, my apache.conf points to /var/www, and there are indeed files the
Code:

root@maples-server:~# ls -la /var/www/
total 624
drwxr-xr-x  5 www-data www-data   4096 Apr 28 19:35 .

Here's my apache.conf (with the comments stripped; there were no "end of line" comments):

I also checked sites-enabled/000-default, and everything seems to be fine the

	# Possible values include: debug, info, notice, warn, error, crit,
	# alert, emerg.
	LogLevel warn

	CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Additionally, the connections are no longer showing up in /var/log/apache2/access.log. The last access time in that file is from before the update. I don't know enough about systemd to know if it is responsible for redirecting the logs to somewhere else...

At this point, I have no idea why it's not working. If anyone could point me in the right direction, I would really appreciate it.
Thanks!

EDIT: After looking around some more, it seems that the output of "apachectl -S" is helpful. So here it is:
Code:

root@maples-server:~# apachectl -S
AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message

It appears that it's looking in a subdirectory html, which was not the case previously (before the upgrade). I've currently got a (ugly but useable) work-around using a symlink:
Code:

root@maples-server:~# cd /var/www/
root@maples-server:/var/www# rm -r html/
root@maples-server:/var/www# ln -s /var/www/
root@maples-server:/var/www# mv www html
root@maples-server:/var/www# ls -l html
lrwxrwxrwx 1 root root 9 Apr 28 22:36 html -> /var/www/

While this does work, I'd like to find the proper way of doing it. Any ideas?

Hi,

I'm on WMware workstation with debian Wheezy.
I have a problem when a restart the Dchp.
It said Bad subnet number/mask combination.

This is logs:

root@debian-main:/# /etc/init.d/isc-dhcp-server restart
dhcpd self-test failed. Please fix /etc/dhcp/dhcpd.conf.
The error was:
Internet Systems Consortium DHCP Server 4.3.1

exiting.

And this my file dhcpd.conf:

# A slightly different configuration for an internal subnet.
subnet 192.168.10.1 netmask 255.255.255.0{
range 192.168.10.1 192.168.10.15;
# option domain-name-servers ns1.internal.example.org;
# option domain-name "internal.example.org";
option routers 192.168.10.254;
option broadcast-address 192.168.10.255;
default-lease-time 600;
max-lease-time 7200;
}

For me it's the good subnet number/mask combination.

Can you help me please?

Thanks you,

Pierrick

When looking at .htaccess on our server, I see that the developers included the following lines:

RewriteRule (services/.*) $1 [L] # adjust the regex to what you want.
RewriteRule ^$ app/webroot/ [L]
RewriteRule (.*) app/webroot/$1 [L]

No idea what the first RewriteRule actually does
Not sure about the ^$ in the 2nd rule
I understand the 3rd rule.


I would appreciate a quick explanation. Thank you very much in advance.
