Re: webservers not responding properly after hardware change (Apache Users)

What you're saying is that you can't connect to any of the servers behind the router.
So NS1 is not able to communicate at all (ping or anything) to NS2.

This seems to be a routing issue that you need to resolve at the router level.

Your network config isn't anywhere close to normal. It makes no logical sense.

Aside from that if you replaced a network card then maybe your MAC address changed and you need to reconfigure the router.

Hello,

I have setup two webservers on my network, one connected directly to the ISP with an ethernet card installed to bring it to the router where, it was give an internal ip address and ports opened for ftp, smtp and pop. It is ns1. ns2 is behind the router and handles http, dns and ssh. Mail is currently being properly delivered although my smtp server going out is no longer working for obvious reasons.

I can't ping ns1 from ns2. apachectl say my configuration is correct. The only change I made that I can see is the ethernet card in ns1 died. How would this impact my DNS?

None of the domains on ns2 are available on the web although the websites on ns1 are.

The attached diagram shows before and after. Any help would be greatly appreciated.

It appears that the apache webserver is already loaded and that might be the problem, although it is not serving any pages. The following is my terminal output.

ns2:~ norman$ apachectl -t
Syntax OK
ns2:~ norman$ apachectl restart
launchctl: CFURLWriteDataAndPropertiesToResource(/System/Library/LaunchDaemons/org.apache.httpd.plist) failed: -10

ns2:~ norman$ apachectl start
launchctl: CFURLWriteDataAndPropertiesToResource(/System/Library/LaunchDaemons/org.apache.httpd.plist) failed: -10
org.apache.httpd: Already loaded
ns2:~ norman$

Hello,

I didn't replace a card, I lost a card. The old router was replaced with a new router and reconfigured and ports opened as per the diagram in the link. Aside from that, how should the network be logically setup? It looked logical enough to me in the old configuration.
