lrzsz

Tools for zmodem/xmodem/ymodem file transfer

Lrzsz is a cosmetically modified zmodem/ymodem/xmodem package built from the public-domain version of Chuck Forsberg's rzsz package. These programs use error correcting protocols ({z,x,y}modem) to send (sz, sx, sb) and receive (rz, rx, rb) files over a dial-in serial port from a variety of programs running under various operating systems.

sx

Scalable public and private cloud storage

Skylable Sx is a reliable, fully distributed cluster solution for your data storage needs. With Sx you can aggregate the disk space available on multiple servers and merge it into a single storage system. The cluster makes sure that your data is always replicated over multiple nodes (the exact number of copies is defined by the sysadmin) and synchronized. Additionally Sx has built-in support for deduplication, client-side encryption, on-the-fly compression and much more.
