during the startup of my Debian Sarge Stable, I get following error messages:

this is a very important PROXY / DNS server for ca. 300 clients
it seems the system cannot finde some modules.
how dangerous is, to run this server without a random number generator ?
when the random number generator is exactly required ?
or I can really sleep well if I blacklist these all modules ?
kind regards
chris

Re: random number generator
It looks like Debian simply tries to load all the modules regardless of whether the corresponding hardware exist or not.
check up /etc/rc.sysinit (I am not sure) which loads most of the drivers and call other scripts to load drivers.
I faced similar kind of issue in slackware where it tries to load all drivers
Hope this helps,
Gopi

Re: random number generator
You're not doing high level entropy testing and development, or physics calculations. You're not doing anything which would require true random numbers (just like 99.9% of the rest of us).
The '/dev/random' and '/dev/urandom' are good enough.

Re: random number generator
I would not tolerate this problem on a production server for any length of time.

Re: random number generator
I've actually never used a system with a Hardware Random Number Generator, and i've used many thousands of systems.
I wasn't aware that *ANY* HP server came with one, regardless of whether it was PARISC, x86 or IA64!

Re: random number generator
but howto check if my hardware support
random number generator ?
is it any tools for linux or windows ?

Re: random number generator
- the one in AMD 768 chipset
- the one in some Intel i810 series chipsets
- the one in VIA Nehemiah CPUs (mostly seen in newer Mini-ITX motherboards).
The i810_rng was an older version of the driver, which supported only i810 chipset RNG. Later a generalized version with more hardware support was made, and it was named "hw_random".
Before these chipsets, the hardware random number generator was a feature only in some SSL accelerators or other specialized hardware. Since the hardware RNG is not very difficult to implement and cryptography is getting more important, someone had an idea to add it to a basic PC chipset.

Re: random number generator
Thus meaning that the system this is running on does not have those pices of hardware.

Re: random number generator
No, you don't need that. The CPU has a math coprocessor and all the power it needs built in. Software random number generation built into the OS will more than do the job.
Apologies if I confused anyone here.
