【摘要】 Linux系统性能优越,可靠性强,尤其是其源代码开放用户可以根据需要任意修改系统性能的特性,可为使用者提供免费的服务,为用户节省大量的经费支出,增强了系统使用的灵活性,尤其是IP遂道技术的日益成熟,使该系统的可靠性更强.在这里主要介绍IP隧道的建立,基于Linux系统的2个文件:new tunnel.c和ipip.c,对利用隧道技术实现Linux下的虚拟专网传输不同协议下的数据包提出建议.更多还原

【Abstract】 Linux System has been gotten much attention since it is brought to the world.People prefer it much for the reason that Linux System has excellent quality,especially for its original code openning users can willfully revise the system performance.In addition,it provides free service so as to save much expenditure,and strengthen its flexibility.Furthermore,IP tunnel technology is becoming more mature,Linux System tends to be more dependable and has good application prospect.This paper demonstrates the establishment of IP Tunnel.Based on two files : new-tunnel.c and ipip.c,some suggestions are put forward on how to transfer database package under different agreements by utilizing tunnel technology to realize virtual special internet in Linux system.更多还原
