use direct IP instead of mersenne.org?

[ixfd64]

Can we have Prime95 use the direct IP for PrimeNet (71.6.220.163) instead of v5.mersenne.org? That way, it can still contact the server should the user have DNS issues, etc.

But what if "The Powers that Be" wish to move the server from one IP to another?

Why do you think DNS exists?

If the user is having DNS issues that's the user's problem.

The OP did not say that the client should use a fixed IP only. The client could use DNS lookup ordinarily, falling back on the fixed IP if the DNS lookup was unsucessful. Slicker would be to make the 'fixed' IP variable, i.e., record the last successful DNS lookup in local.txt and use that if the DNS lookup fails.

That said, I'm not convinced there's a real problem here. DNS problems are usually temporary, and a temporary breakdown in communication rarely causes harm. The client just keeps chugging away until contact is restored.

If the question was how to do it, here goes:

Hi!
Got to this postings , because I was wondering what this message was:

[Comm thread Nov 25 05:53] Getting assignment from server
[Comm thread Nov 25 05:53] CURL library error: Couldn't resolve host 'v5.mersenne.org'
[Comm thread Nov 25 05:53] CURL library error: Couldn't resolve host 'v5.mersenne.org'
[Comm thread Nov 25 05:53] Visit http://mersenneforum.org for help.
[Comm thread Nov 25 05:53] Will try contacting server again in 70 minutes.

Seemingly a C - library related thing - right?

Got this prob throughout half the night and the morning, from

[Comm thread Nov 25 05:53] CURL library error: Couldn't resolve host 'v5.mersenne.org'

till

[Comm thread Nov 25 09:24] CURL library error: Couldn't resolve host 'v5.mersenne.org'

and then

[Comm thread Nov 25 10:34] Getting assignment from server
[Comm thread Nov 25 10:34] PrimeNet success code with additional info:
[Comm thread Nov 25 10:34] Server assigned P-1 factoring work.

for all 4 cores/workers.

But DNS issues, I don'T know. I normaly don't have DNS issues!
So what ?

My first guess would be that your network/Internet connection was not working at those times. The first thing to need the Internet during a connection is resolving the DNS name, and Prime95 just happens to use the CURL library. So yes, it could be a problem related to DNS or the CURL library, but the more fragile link, and so the more likely culprit, is your Internet connection. Unless you can confirm that during the time this was happening you were able to access the Internet.

Or it could just be that the PrimeNet server was down during that time; it wouldn't be the first time that's happened.

If the PrimeNet server was down, the DNS servers, which are hosted elsewhere, should still give you the IP; you'd see a different error.
