[Solved] No entropy gathering module detected?

Postby RobinVossen » Wed Dec 19, 2007 1:14 pm

Well I try to call my OpenOffice over a Application server.
And I get no entropy gathering module detected..
What is this error?
I call the system using ssh -X and both the Boxes are Gentoo 2007.0 boxes.

Can anyone help me with that?

Cheers,
Robin

It's probably a message from ssh. The Linux kernel can provide random numbers which use environmental inputs to augment the randomness. This is often used by crypto software.

It doesn't sound normal to me: the "entropy-enhanced" random number generation is a normal part of the kernel, but I could not begin to tell you if the message is anything to worry about, or how to troubleshoot the problem.

Well I had the same problem when I did work with a Chrooted system and imported OpenOffice into that.
You say its a change that I need to make sure that the Random pool (/dev/random and /dev/urandom) are working correctly?

Well, that would make sense, since the /dev/... entries would not be accessible. You should be able to simply copy them into the chroot jail, so that they appear as /dev/{random,urandom} to the programs running in the jail. There's nothing special about /dev.

The trick will be how to copy the device nodes, since you can't just say "cp /dev/random /some/where/else". You may actually have to use tar or something that knows how to handle copying the device node.
