reboot, then reaccess the Rapidshare link, if using firefox you may be able to restore your file (this may be obsolete depending upon how large the file is), if it continues to go slow i would recommend portfowarding (Port forwarding allows remote computers (e.g. public machines on the Internet) to connect to a specific computer within a private LAN.[3]
For example:
* forwarding port 80 to run an HTTP webserver within private LAN from internet
* forwarding port 22 to allow Secure Shell access within private LAN from internet
* forwarding port 21 to allow FTP access within private LAN from internet
Modern Linux machines achieve this by adding iptables rules to the nat table: with target DNAT to the PREROUTING chain, and/or with target SNAT in the POSTROUTING chain.
BSD and Mac OS X machines use a similar tool named ipfw. The ipfw tool is likely already running as a built-in part of the operating system's kernel.
Some common caveats with port forwarding include:
* The need to forward the packets that come to the router's forwarded port as well as the need to rewrite them so that the machine to which the port is forwarded can reply to the original source address, which in turn leads to the inability of the destination (private) machine to see the actual originator of the forwarded packets, and instead see them as if originating from the router
* Only one networked machine can use a specific forwarded port at one time
* Traditional port forwarding allows the entire world access to the forwarded port, slightly reducing network security
Port forwarding can also be used within a single machine. Port forwarding is necessary for a standalone computer if any of the following conditions are true:
* The computer is using a shared IP address.
* Internet Connection Sharing is enabled.
* A router is being used with NAT enabled.
In a typical home networking setup, internet access is through a DSL or Cable modem. That modem may be connected to a router, which is then connected to the networked computers by Ethernet or WiFi. The router is the device that the Internet sees; it holds the public IP address. The computers behind the router, on the other hand, are invisible to the Internet as they hold a local IP address each. Port forwarding is necessary in the router because computers will send information directed to the public IP address and the router needs to know where to send that information.[4]
Port forwarding is commonly done on Unix computers where port numbers numbered below 1024 can only be accessed by software running as the root user. Running as root can be a security risk, so some people use port forwarding to redirect incoming traffic from a low numbered port to software listening on a higher port. For example, a web server may be listening on a port such as 8080 for traffic redirected from the restricted port 80. A port may be forwarded for use by either the TCP protocol, the UDP protocol, or both.)
