[Chris McDonough, on Mon, 27 Dec 1999] :: Adding to what Patrick said, if you want to see a list of RPM packages :: installed on your machine, type: :: :: rpm -aq And if you don't want to sift through all that output for just the pkg you want, you can type, e.g.: rpm -aq | grep apache :: By default, a Zope setup will bind itself to TCP port 8080 (this can be :: changed in ZOPEHOME/z2.py). A typical from-source Apache setup will :: bind itself to TCP port 8080 as well (this can be changed in :: APACHEHOME/conf/httpd.conf). I would recommend changing the port that :: Apache listens on to 80 if it's hogging 8080. You can do this by :: editing your Apache setup's conf/httpd.conf line. The line that reads :: "Port 8080" should be changed to "Port 80". Then restart Apache (use :: "apachectl restart"). For good measure, restart Zope too (use the :: "stop" script, then use the "start" script). Oddly, it appears that people who use the default RedHat Apache install don't get `apachectl`, since it is normally in the source and needs to be manually moved to a binary directory. At least I noticed this on 6.1. :( Of course, you can always just do `/etc/rc.d/rc3.d/httpd restart` instead, or make your own little Bash script to call this.
