Mailing List Archive: [mod_backhand-users] mod

Hello,
I have my cluster and all the machines have mod_backhand configure whith =
apache.
Do i need to define all the machines in the DNS like
www 300 IN A ip1
300 IN A ip2
300 IN A ip3
300 IN A ip4
Why can't i defined just the first (or anyone else), which can redirect a=
ll the request ?

When i compile apache and mod_backhand, everything goes well, but the mod=
ule byHostname.so isn't created.
is it normal ?
I then created it myself by the command line /full/path/to/apache/bin/apx=
s -c -o byHostname.so byHostname.c
but i can't use it: i put this in the apache configuration file:

<Directory /usr/local/apache/cgi-bin>
BackhandFromSO libexec/byHostname.so byHostname my_machine
</Directory>

and the logs tells me:
Syntax error on line 480 of /usr/local/apache/conf/httpd.conf:
Invalid command 'BackhandFromSO', perhaps mis-spelled or defined by a mod=
ule not included in the server configuration

What's wrong ?

Thanks

Either way will work fine. You can have an any, some, or all defined in your
DNS record. There are advantages and disadvantages to each configuration.

Hmm... if complied via apxs, yes. If you actually compile mod_backhand in the
Apache source tree (with the ./precomile script) then it will build it for
you.

After you do that (that command should work fine), you need to manually copy
it the the /path/to/apache/libexec directory.

I am not sure. BackhandFromSO should work fine. Can you confirm that
mod_backhand is working before that? i.e. you can see the status page and you
can use the normal "Backhand" directives?
