1 Network Block Device (TCP version) 2 3 What is it: With this compiled in the kernel (or as a module), Linux 4 can use a remote server as one of its block devices. So every time 5 the client computer wants to read, e.g., /dev/nb0, it sends a 6 request over TCP to the server, which will reply with the data read. 7 This can be used for stations with low disk space (or even diskless) 8 to borrow disk space from another computer. 9 Unlike NFS, it is possible to put any filesystem on it, etc. 10 11 For more information, or to download the nbd-client and nbd-server 12 tools, go to http://nbd.sf.net/. 13 14 The nbd kernel module need only be installed on the client 15 system, as the nbd-server is completely in userspace. In fact, 16 the nbd-server has been successfully ported to other operating 17 systems, including Windows. 18
