Thread: Remote login

I was using exec over TCP to connect to a remote server.i was using send,recv functions to get success/failure of the login on passing username and password.
i was getting a message some thing like on invalid login:
msg:

[compat]: 3004-300 You entered an invalid login name or password.


rexecd: 0826-604 The login is not correct.

But wen i tried to use ssh instead of exec i am getting a message something like:
SSH-1.99-OpenSSH_3.9p1
for both correct as well as wrong login details.is there a way in which my code runs in a similar way as exec even with ssh returning an error msg for wrong login details?

SSH isn't a text-based system, it's an encrypted data stream. What you are seeing is the welcome message.

Yeah i understand that,all i need to know is if there is a way to authenticate using send,recv methods.Also i would like to know if there is any alternative to implement this functionality

No, not the way you're thinking (at least, not the way I understand your question). SSH uses SSL, meaning that the data being written via send and read via recv is encrypted via whatever method was setup in the SSL connection. The simple act of "sending" a packet over SSH, or any SSL connection can involve reading and writing of data over sockets. You would have to use an SSL library to connect (openssl comes to mind), read and write. After that, you would have to do whatever the SSH protocol is expecting for login. Unfortunately, I know nothing about the SSH protocol.
