Dear Lewis:

According to the application developer, we the reason Nutch does not crawl is because of our local environment (our server) not able to search itself or a host file issue.

So currently, my hostname is different than my domain name and that is what is causing the issue. When I do a nslookup from the server it resolves to the correct IP address. My question was more towards what it is that I have to put on the host file for Nutch to crawl correctly.

Thank YOU for all your help!

Alex

Hi Alex,

By referring to 'hosts' file, I assume you mean some seed list that you are providing to Nutch for a crawl?

If this is the case then I understand (and have experienced) what you are referring to. In the past, and in my case, I managed to define the difference between host name and domain name to the fact that the actual page you are trying to fetch E.g. domain name, is a redirect from the original host name. There is a property in nutch- default which you can try adding to nutch-site which deals with http- redirects. I think I set the redirect to a value of >2 or >3 and it was at this stage that Nutch began to fetch more urls from the initial seed list.

Can you please try the above and post if this is the solution. If it is not then I am unsure, I could maybe try crawling the domain you are referring to if you would post it.

Lewis

Hi,

I am new to Nutch.  I have an application that uses Nutch to
search.  I have configured the application so that Nutch can run.
However, after a lot of troubleshooting I have been pointed to the
fact that there is something wrong with my hosts file.  My hostname
is different than my domain name and that "seems" to make Nutch stop
in depth 1.  Does anyone have any idea of what is the correct
configuration of the hosts file so that nutch runs properly?

My domain name resolves fine.  Please help me!

Here are the logs of the indexing:

Stopping at depth=1 - no more URLs to fetch.
