The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

  • The Grade of the Solution
  • The Zone Rank of the Expert Providing the Solution
  • The Number of Author and Expert Comments
  • The Number of Experts Contributing
  • The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Can't create socket as non-root user

Asked by Chireru in Perl Programming Language

Tags: , , ,

This problem's been bothering me for a while.  I have a script that runs as nobody, but DNS lookups are failing.

After lots of testing, I've built a script with the basic Net::DNS examples, and found that Net::DNS::Resolver uses IO::Socket::INET to create a socket, which fails (somehow) and does not create the socket, which causes Net::DNS::Resolver to give me the error, "could not get socket".  The script works fine when run as root, but fails when run as any other user.

This is FreeBSD 5.3, in a jail using perl 5.8.6, and the latest versions of IO::Socket and Net::DNS.
The jail has these options:
security.jail.allow_raw_sockets=1
security.jail.sysvipc_allowed=1

I REALLY don't want to run this as root..  does anyone have a clue what is causing this to fail, or a way to debug IO::Socket::INET?Start Free Trial
