Forum OpenACS Q&A: Re: OpenACS / IPCop / Error: nssock: failed to listen on 200.200.200.200:8000: Cannot assign requested address
I set the hostname and address to 127.0.0.1 within my sample-config.tcl file and found that I was able to browse to the homepage. (My sample-config.tcl file follows).
Hopefully I'll explain this clearly but let me know if anything sounds odd.
I have two machines. One is a firewall running ipCop and the other a redhat 9 linux workstation. My firewall machine has two network cards. One card links to my ASDL modem and the other links to my linux workstation.
I have ipCop configured for GREEN+RED interfaces. The RED interface is for the external network (internet access via my ASDL modem) and the GREEN interface is for my internal network (ie my linux workstation).
I set the GREEN interface address to 200.200.200.200.
inet addr:200.200.200.200
Bcast:200.200.200.255
Mask:255.255.255.0
The ip address for my RED interface is set via DHCP and I set my DHCP hostname as ipcop.
The ip address of my firewall machine is supplied by my internet service provider. It's not a static ip address.
inet addr:203.217.68.128
Bcast:203.217.68.255
Mask:255.255.255.0
The ip address of my workstation is provided by ipCop. I enabled ipCop's DHCP server function - providing a range of addresses between
200.200.200.200
and
200.200.200.250
I defined the "primary DNS" setting on the "DHCP server configuration screen" as 200.200.200.200
ifconfig on my local workstation tells me that the ip address of my workstation is
inet addr:200.200.200.201
Bcast:200.200.200.255
Mask:255.255.255.0
