Thanks to Phil for the excellent software and resources -- I'll be sending a donation soon. I've been using it since last year and it has also been a valuable learning experience. And thanks to Ross for making things easier and faster to set up with the live cd. I recently installed 1.19.1 livecd on one machine on my lan, no problems. Then I installed a "slave" machine with same software and moved a camera from the "master" machine to distribute the load a bit. I am still not getting a remote feed from the slave machine, but when I try to access the remote feed from any computer in my (home) lan several instances of httpd2 start up on the slave. I can make them go away by changing the "Function" setting for the remote feed on the master computer from "monitor" to "none". Also, the httpd access and error logs on the slave grow to about 600 MB EACH in about a day's time.

Any insight on why so many (sometimes 12 or more) occurrences of httpd2 exist would be very welcome.

Hi Dave,

I'm not sure what the 'client denied by server configuration' error means though I suspect you could google for it and find out easily enough. I imagine it's related to some apache config somewhere.

However the large numbers of servers is not unusual and is by design. For instance on one of my servers the httpd.conf lists this

# prefork MPM
# StartServers: number of server processes to start
# MinSpareServers: minimum number of server processes which are kept spare
# MaxSpareServers: maximum number of server processes which are kept spare
# MaxClients: maximum number of server processes allowed to start
# MaxRequestsPerChild: maximum number of requests a server process serves
<IfModule prefork.c>
StartServers 8
MinSpareServers 5
MaxSpareServers 20
MaxClients 150
MaxRequestsPerChild 1000
</IfModule>

which basically means it will always start at least 8 servers, and will try to keep 5 spare up to a maximum of 20. So if there were 6 connections there would be 11 servers running, the original 8 plus 3 new ones to make sure that 5 were still available.

It may be your config does the same, as this isn't something I've changed myself. However I would suggest trying to remove the error first as this may also be having some impact.

Phil,
