Of course this is possible. A TCP connection is uniquely identified by the 5-tuple {localIP, localPort, remoteIP, remotePort, protocol}. The remoteIP and remotePort may be * in case of a passive open, i.e. a socket in LISTEN status, as is the case of a http server. AS a matter of fact, you may not even need separate Apache instances. One instance can listen for connections on multiple addresses and ports, i.e. have multiple Listen directives. -ascs -----Original Message----- From: Sean Brown [mailto:seanmichaelbrown@xxxxxxxxx] Sent: Tuesday, October 25, 2005 10:25 PM To: users@xxxxxxxxxxxxxxxx Subject: [users@httpd] Multiple instances bound to separate IPs? Is it possible to run two separate instances of Apache, both on port 80, but each bound to a different IP? So, for instance one, I'd have this in the httpd.conf: Listen 192.168.1.1:80 And in the other, I'd have have: Listen 192.168.1.2:80 If I started each with a specification of configuration file, would it work, or would I get an error about a service already bound to port 80? I'd start them like so /usr/local/apache2/bin/httpd -f /usr/local/apache2/conf/httpd.conf -k start /usr/local/apache2_php5/bin/httpd -f /usr/local/apache2_php5/conf/httpd.conf -k start Thanks in advance, Sean --------------------------------------------------------------------- The official User-To-User support forum of the Apache HTTP Server Project.
