UUCP

UUCP - Unix to Unix Copy Program is a protocol used to transfer files between computers primarily over ASCII dial-up connections. It was widely used to implement e-mail and Usenet News prior to the widespread deployment of the Internet.

UUCP is primarily used with ASCII dial-up lines. Taylor UUCP can also transfer files over a TCP/IP connection across the Internet. In most cases, if you are transferring over the Internet, you would want to use modern protocols, SMTP for e-mail (in conjunction with ETRN for servers that are intermittently connected), FTP for file transfer, ssh for remote program execution, but there are legacy applications wired into UUCP.

There are many UUCP implementations. Taylor UUCP, which introduced a sliding window transfer protocol, offers the best throughput. Taylor UUCP also addressed security issues present in previous UUCP implementations. Eskimo North uses Taylor UUCP but at present we have it enabled for dial-up usage only. If someone has a pressing need for UUCP over IP we will consider enabling IP support.
