Impolite crawling using NUTCH
Hi team,
Can we use NUTCH to do impolite crawling?
Or is there any way by which we can disobey robots.text?
With Regards
Jyoti Aditya

Hi Jyoti,
in this case, the answer is simple: the robots.txt whitelisting
was never ported from 1.x to 2.x ;(
Best,
Sebastian

Hi Chris/Team,
Whitelisting domain name din't work.
And when i was trying to configure selenium. It need one headless browser to be integrated with.
Documentation for selenium-protocol plugin looks old. firefox-11 is now not supported as headless browser with selenium.
So please help me out in configuring selenium plugin configuration.
I am yet not sure, after configuring above what result it will fetch me.

Hi Chris,
Thanks for the response.
I added the changes as you mentioned above.
But I am still not able to get all content from a webpage.
Can you please tell me that do I need to add some selenium plugin to crawl
dynamic content available on web page?
I have a concern that this kind of wiki pages are not directly accessible.
There is no way we can reach to these kind of useful pages.
So please do needful regarding this.

Hi Chris/Team,
I am using Nutch2.3.1 with mongoDB configured.

Even though I have added whitelist property in my nutch-stie.xml,
I am not able to crawl.

Re: Impolite crawling using NUTCH
Posted by "Mattmann, Chris A (3010)" <ch...@jpl.nasa.gov>.
Hi Jyoti,
I need a lot more detail than “it didn’t work”. What didn’t work about it? Do you have a log
file? What site were you trying to crawl? What command did you use? Where is your nutch
config? Were you running in distributed or local mode?
Onto Selenium – have you tried it or simply reading the docs, you think it’s old? What have
you done? What have you tried?
I need a LOT more detail before I (and I’m guessing anyone else on these lists) can help.
Cheers,
Chris

Hi Chris/Team,
Whitelisting domain name din't work.
And when i was trying to configure selenium. It need one headless browser to be integrated with.
Documentation for selenium-protocol plugin looks old. firefox-11 is now not supported as headless browser with selenium.
So please help me out in configuring selenium plugin configuration.
I am yet not sure, after configuring above what result it will fetch me.

Can you please tell me that do I need to add some selenium plugin to crawl
