[Libssh] Implementing a SSH server

[Aris Adamantiadis]

Hello,

after reading server.c source, it seems that what you want to do is not
possible using only the external API. So I understand why you got out
some code from ssh_bind_accept() into your own code.
Your code has the two lines:
    session->dsa_key = dsa;
    session->rsa_key = rsa;
How did you define the variables dsa and rsa ? You will have to set them
as explained in ssh_bind_accept().

It's really ugly but it might work as expected.
Something possible would be changing your app a little to use
ssh_bind_accept by giving it a file descriptor in the to-be-accepted state.

I agree it lacks a function like
ssh_accept_fd(SSH_OPTIONS options, int fd);

Maybe in 0.3

Regards,

Aris
