You can  do that easily in C

...  there is "getpass" routine for get your input without echoing ....

use gethostbyname , connect , send , recv  etc to connect to the remote host ......

getty prog is useful here ...

 

As far as I remember "rlogin" source was included in one book by W RICHARD STEVENS

( unix n/w programming ???? ) .......

 

If you look at the RFC 1282 , it will give info about how to format the messages  between the

 client/server .......

telnet's implementation is different from rlogin's

Subject: about remote login

Hello... I am currently researching about remote login and came across Python's Telnetlib. However, I cannot find a similar library in C. Does anyone know if there is an equivalent library in C or the equivalent functions can be implemented in C.

 

Attached here is the sample code in Python that I want to implement in C:

 

import getpass
import sys
import telnetlib

HOST = "localhost"
user = raw_input("Enter your remote account: ")
password = getpass.getpass()

tn = telnetlib.Telnet(HOST)

tn.read_until("login: ")
tn.write(user + "\n")
if password:
    tn.read_until("Password: ")
    tn.write(password + "\n")

tn.write("ls\n")
tn.write("exit\n")

 

thanks very much

print tn.read_all()
