Good afternoon, all -

I'm new to the list, I'd like to first thank the developers of GNUTLS for their fine work. We appreciate it.

We're developing a threaded application in our development department, and it's going alright so far. However, we keep getting an error which we believe comes from generate_dh_params(). The error is as follows:

Fatal: no entropy gathering module detected

The most we've been able to gather using google.com and assorted resources is that entropy cannot be established. The only solution that we had found that was even remotely related to ours just suggested making sure that /dev/{u}random had world-readable permissions. Aside from that, we don't know what to go by.

Any pointers?


That is a libgcrypt error.  Check how you built libgcrypt.  If the
Win32/Linux/Unix RNG can't be used, you might need to run EGD.

You could also try building GnuTLS with --with-nettle.

Hope this helps,
Simon


Simon -

Thanks for the response.

The only argument we're compiling libgcrypt with is '--disable-asm'. I took the origional RPM for libgcrypt-1.2.0-1, and modified it slightly for -1.2.1, just in case. We get this error regardless of which version we're using.

Why wouldn't we able to use the RNG on this Linux platform? What would prevent us?

Thanks!
