Help with libssh2_channel_direct_tcpip_ex

In my code , libssh2_channel_direct_tcpip_ex successfully returns
channel .

while( ( channel = libssh2_channel_direct_tcpip_ex(
session,targethostname , 22 , hostname, 22 ) ) == NULL)

{

   rc = libssh2_session_last_error(session,NULL,NULL,0);

   if (rc == LIBSSH2_ERROR_EAGAIN)

      waitsocket(ConnectSocket, session);

   else

      break;

}

When I use the channel for below purpose

while( (rc = libssh2_channel_exec(channel, commandline)) ==
LIBSSH2_ERROR_EAGAIN );

I get the rc = -22 i.e. "LIBSSH2_ERROR_CHANNEL_REQUEST_DENIED" .

When I look further , the error is actually coming from packet.c file
from below method

"_libssh2_packet_requirev" as the value of ret in below call is 100 i.e.
"d"

int ret = _libssh2_transport_read(session);

Can you give me hint to explore further into where could I be going
wrong ?

Thanks & Regards,
Ashish Kumar
