Kermit is a program package for transferring data between different computers. It was named after Kermit the frog from the Muppet Show . The program was developed at Columbia University in New York since 1981 and maintained there until June 30, 2011. Most of the software was released under an open source license . The original project has not been maintained since then, but there are Kermit 95 , C-Kermit and E-Kermit as active follow -up projects .


Kermit uses the Kermit protocol to transfer files . Similar to UUencode , in the basic setting all characters to be transmitted are encoded as 7-bit ASCII characters. Both the control characters (the first 32 characters of the ASCII code) and all characters outside of the character set are marked with a corresponding identifier. However, this can be configured so that 8-bit characters can also be transmitted on the corresponding lines.

In addition to pure data transfer, Kermit can also be used to log on to another computer - if Kermit is running in server mode there - and some of it can be operated.

Since Kermit is available for almost every operating system , the program is often used for cross-system data transfer.

The Kermit protocol was originally intended for peer-to-peer connections in order to achieve a high level of data security even with poor connections or lines.
