I never got what was supposed to come before the Furthermore. So don't know what you said before, but as to this: That's kind of what I was after in the first place, before dealing with the compression. I hadn't heard of netcat, but the approach is nearly identical to what I was trying to do. What I wanted was (as I said in a previous message) was to shrink the amount of physical data sent across the network. That's what the compression/archiving was for. The NFS wasn't supposed to copy each file across. The idea was to either have something like a .tar.bz2 file but with better compression that gets opened from the remote NFS directory and extracted to the local HDD. > if this is a one-time thing, the other guys are right on; just use an eSATA or USB3 drive (not USB1/2, the polling will kill > you) and sneakernet it. Then use rsync if things need to be updated periodically. Sneakernet is exactly what I was trying to AVOID. The goal was to have something that I can boot say from a thumb drive, then run a script on the drive that does all the work for me. :) And while a multicast netcat type thing would work, I still need it to be compressed, hence my first question about what would be the best compressor that either supports piping or unix permissions and special files. Thanks though. I'd like to hear more about this multicasting netcat idea. --- Dan ;A�1 o,0�A�'t just about our laws; this is about who we are as a people. This is about whether we value one another, whether we embrace our differences rather than allowing them to become a source of animus." Earlier this year tow psychologists in Canada declared that pedophilia is a sexual orientation just like homosexuality or heterosexuality. Van Gijseghem, psychologist and retired professor of the University of Montreal, told members of Parliament, "Pedophiles are not simply people who commit a small offense from time to time but are grappling with what is equivalent to a sexual orientation just like another individual may be grappling with heterosexuality or even homosexuality." He went on to say, "True pedophiles have an exclusive preference for children, which is the same as having a sexual orientation. You cannot change this person's sexual orientation. He may, however, remain abstinent." When asked if he should be comparing pedophiles to homosexuals, Van Gijseghem replied, "If, for instance, you were living in a society where heterosexuality is proscribed or prohibited and you were told that you had to get therapy to change your sexual orientation, you would probably say that is slightly crazy. In other words, you would not accept that at all. I use this analogy to say that, yes indeed, pedophiles do not change their sexual orientation." Dr. Quinsey, professor emeritus of psychology at Queen's University in Kingston, Ontario, agreed with Van Gijseghem. Quiney said pedophiles' sexual interests prefer children and, "there is no evidence that this sort of preference can be changed through treatment or through anything else." In July, 2010, Harvard health Publications said, "Pedophilia is a sexual orientation and unlikely to change. Treatment aims to enable someone to resist acting on his sexual urges." Linda Harvey, of Mission America, said the push for pedophiles to have equal rights will become more and more common as LGBT groups continue to assert themselves. It's all a part of a plan to introduce sex to children at younger and younger ages; to convince them that normal friendship is actually a sexual attraction." Milton Diamond, a University of Hawaii professor and director of the Pacific Center for Sex and Society, stated that child pornography could be beneficial to society because, "Potential sex offenders use child pornography as a substitute for sex against children." Diamond is a distinguished lecturer for the Institute for the Advanced Study of Human Sexuality in San Francisco. The IASHS openly advocated for the repeal of the Revolutionary war ban on homosexual serving in the military. The IASHS lists, on it's web site, a list of "basic sexual rights" that includes "the right to engage in sexual acts or activities of any kind whatsoever, providing they do not involve nonconsensual acts, violence, constraint, coercion or fraud." Another right it to, "be free of persecution, condemnation, discrimination, or societal intervention in private sexual behavior" and "the freedom of any sexual thought, fantasy or desire." the organization also says that no one should be "disadvantaged because of age." Sex offender laws protecting children have been challenged in several states, including California, Georgia and Iowa. Sex offenders claim the laws prohibiting them from living near schools or parks are unfair because it penalizes them for life. While I understand pedophiles wanting to be recognized as just an alternate lifestyle, I'm not sure how I feel about that. On the one hand, it seems quite wrong to me. But that could just be my paranoia speaking. I see the laws being repealed and then child sex outlets (think prostitution establishments) cropping up here and there in the USA. But on the other hand, it's true that many people are being punished, not for what they HAVE done, but for what they MIGHT HAVE DONE, now OR IN THE FUTURE. That, I cannot agree with. You don't punish people for what MIGHT happen! But that's EXACTLY what our society is doing! Well, I'd be curious to hear your thoughts on the matter.
