Description: Redirect TCP connections
It can run under inetd or stand alone (in which case it handles
multiple connections). It is 8 bit clean, not limited to line
mode, is small and light. Supports transparency, FTP redirects, http
proxying, and bandwidth limiting.
.
redir is all you need to redirect traffic across firewalls authenticate
based on an IP address etc etc. No need for the firewall toolkit. The
functionality of inetd/tcpd and ""redir"" will allow you to do everything
you need without screwy telnet/ftp etc gateways. (I assume you are running
IP Masquerading of course.)

44th Known Mersenne Prime Found!!
Lightning strikes twice. On September 4, 2006, in the same room just a few
feet away from their last find, Dr. Curtis Cooper and Dr. Steven Boone's CMSU
team broke their own world record, discovering the 44th known Mersenne prime,
2^32,582,657 - 1. The new prime at 9,808,358 digits is 650,000 digits larger
than their previous record prime found last December. However, the new prime
falls short of the 10 million digits required for GIMPS to claim the
Electronic Frontier Foundation $100,000 award.
With five record primes found in less than 3 years, GIMPS has been on an
incredible lucky streak. Never before have Mersenne primes been bunched so
closely together. When looking at the exponents, we expect only 1.78 Mersenne
primes between powers of two, and prior to 2003, a maximum of 3 Mersenne
primes were found between powers of two. The last 5 Mersenne prime exponents
all fell between 224 and 225 -- and we haven't finished testing all the
exponents in that range!
The new prime was independently verified in 6 days by Tony Reix of Bull S.A.
in Grenoble, France using 16 Itanium2 1.5 GHz CPUs of a Bull NovaScale 6160
HPC at Bull Grenoble Research Center, running the Glucas program by Guillermo
Ballester Valor of Granada, Spain.
Dr. Cooper and Dr. Boone could not have made this discovery alone. In
recognition of contributions made by the project coordinators and the tens of
thousands GIMPS volunteers, credit for this new discovery goes to ""Cooper,
Boone, Woltman, Kurowski, et al"". The discovery is the tenth record prime for
the GIMPS project. Join now and you could find the next record-breaking
prime! You could even win some cash.
Perfectly Scientific, Dr. Crandall's company which developed the FFT
algorithm used by GIMPS, will make a poster you can order containing the
entire 9.8 million digit number. It is kind of pricey because accurately
printing an over-sized poster in 1-point font is not easy! This makes a cool
present for the serious math nut in your family.
