Remmina - The GTK+ Remote Desktop Client  v1.4.33
Remmina is a remote desktop client written in GTK+, aiming to be useful for system administrators and travellers, who need to work with lots of remote computers in front of either large monitors or tiny netbooks. Remmina supports multiple network protocols in an integrated and consistent user interface. Currently RDP, VNC, NX, XDMCP and SSH are supported.

◆ remmina_ssh_auth()

enum remmina_ssh_auth_result remmina_ssh_auth ( RemminaSSH *  ssh,
const gchar *  password,
RemminaProtocolWidget *  gp,
RemminaFile *  remminafile 
)
Todo:
Here we should call gint method; method = ssh_userauth_list(ssh->session, NULL);

#define SSH_AUTH_METHOD_UNKNOWN 0x0000u #define SSH_AUTH_METHOD_NONE 0x0001u #define SSH_AUTH_METHOD_PASSWORD 0x0002u #define SSH_AUTH_METHOD_PUBLICKEY 0x0004u #define SSH_AUTH_METHOD_HOSTBASED 0x0008u #define SSH_AUTH_METHOD_INTERACTIVE 0x0010u #define SSH_AUTH_METHOD_GSSAPI_MIC 0x0020u

And than test both the method and the option selected by the user

gp flags title default_username default_password default_domain password_prompt

Some protocols may open new connections during the session. e.g: SPICE opens a new connection for some channels.
