go-telnet

Build Status

Status: Done

Read bytes from stdin and pass them to the remote host. The application works similarly to the well known telnet application, but it lets you read bytes from standard input and wait for response.

Problem Definition

Old telnet does not work in that manner and it requires a script based on expect command. Trying an intuitive solution would end up with that:

$ cat resources/input-data/wp.pl_1.bin | telnet wp.pl 80
Trying 212.77.100.101...
Connected to www.wp.pl.
Escape character is '^]'.
Connection closed by foreign host.

The same execution of go-telnet ends with a received server response:

$ cat resources/input-data/wp.pl_1.bin | go-telnet wp.pl 80
HTTP/1.1 200 OK
Server: aris
