1: 2 IPs, Apache, OpenACS/AolServer, 1 machine...?

Posted by Dave Linsalata on 08/08/01 10:58 PM

Heya

I have a machine with two IPs assigned to it. Is it possible (and
how do I) assign the second, newer IP to openacs and aolserver? Is
there some force host entry I make somewhere?

Thanks
Dave

Yes, you can specify in your AOLserver ini file to what IP address and port the server responds. In the section,

Take a look at http://aolserver.com/docs/config.adp

and pay attention to the section that specifies:

#
# Socket driver module (HTTP)  -- nssock
#
ns_section "ns/server/${servername}/module/nssock"
ns_param   port            $httpport ;# Port for HTTP (typically 80)
ns_param   hostname        $host     ;# This is not the same as your hostname
ns_param   address         $address  ;# This is not the same as your host addr
ns_param   location        "url"     ;# URL for auto-redirects (trailing slash)

You also need to make sure that you have both IP addresses setup on the box. ifconfig -a should tell you if they are.

You have to check the config for apache first, look for the line: Listen and put the ipaddr:port

[shagster@foobar mail]$ grep 'Listen [0-9].*:[0-9].*'
/etc/httpd/conf/httpd.conf 
#Listen 12.34.56.78:80
Listen 10.210.0.104:8000

Note: You'll most likely use port 80. In your aolserver config, look for:

[shagster@foobar aolserver]# egrep '(http.*port|address)' 
/etc/aolserver/nsd.tcl 
# If httpport is set to 80, you'll have to start AOLserver as root and pass the user 
set httpport              8000
set httpsport             8443 
set address               "10.210.0.105"

That is what I do, and it works for me.
