mod_defensible

Hi Falco,

I try your howto http://howtoforge.com/block-spammers-hackers-with-mod_defensible-on-apache2-debian-etch

and all things is ok.My only problem is this line in apache.conf

Code:

DnsblNameserver 145.253.2.75

When I restart Apache restart i become an error

Code:

Restarting web server: apache2We failed to correctly shutdown apache, so we're now killing all running apache processes. This is almost certainly suboptimal, so please make sure your system is working as you'd expect now! (warning).

 

Does

Code:

apache2 -t

show any errors? Any errors in Apache's error log?

 

Code:

 apache2 -t
apache2: bad user name ${APACHE_RUN_USER}

 

Try

Code:

. /etc/apache2/envvars && apache2 -t

 

Code:

/etc/init.d/apache2 start
Starting web server: apache2Syntax error on line 285 of /etc/apache2/apache2.conf:
Invalid command 'DnsblNameserver', perhaps misspelled or defined by a module not included in the server configuration
 failed!
kate:/home/fox# /etc/apache2/envvars && apache2 -t
bash: /etc/apache2/envvars: Permission denied

Look Envvars

Code:

cat /etc/apache2/envvars
# envvars - default environment variables for apache2ctl

# Since there is no sane way to get the parsed apache2 config in scripts, some
# settings are defined via environment variables and then used in apache2ctl,
# /etc/init.d/apache2, /etc/logrotate.d/apache2, etc.
export APACHE_RUN_USER=www-data
export APACHE_RUN_GROUP=www-data
export APACHE_PID_FILE=/var/run/apache2.pid

 

Please run

Code:

a2enmod defensible

and restart Apache.

 

Code:

 a2enmod defensible
Module defensible already enabled

Code:

 /etc/init.d/apache2 restart
Restarting web server: apache2We failed to correctly shutdown apache, so we're now killing all running apache processes. This is almost certainly suboptimal, so please make sure your system is working as you'd expect now! (warning).
 ... waiting Syntax error on line 283 of /etc/apache2/apache2.conf:

Did you maybe put "DnsblNameserver" into your Apache configuration before the modules get loaded?

 

I have the exact same problem, exact same error. I'm using Ubuntu 9.04. My server is already set up with Apache2, so I installed libapache2-mod-defensible and libudns0. Then I enabled mod_defensible with 'a2enmod defensible'. After that I edited /etc/apache2/apache2.conf and put the mod_defensible configuration right before the virtual hosts (exactly like example).

After that I restarted apache2 and I received:

Removing the DnsblNameserver command from /etc/apache2/apache2.conf allows Apache2 to restart properly. Unfortunately all IPs seem to be blocked afterward.

I'm not sure what other relavent information I can provide. The content of my /etc/apt/sources.list file is:

@planet_fox: If you find out how to fix this let me know please.

 

So, I managed to get mod_defensible running after coming across the same problem...the solution will make you facepalm. Ready? okay...here it is:

Code:

<IfModule mod_defensible.so>
DnsblUse On
DnsblServers httpbl.abuse.ch sbl-xbl.spamhaus.org
DnsblNameserver 145.253.2.75
</IfModule>

That's it. You just need to wrap it in <IfModule> tags.
