I like to connect to a SFTP server through a squid3 proxy
A test with filezilla seams to work.
With my test binary I have troubles. At the handshake I get a -2 as error
known as LIBSSH2_ERROR_BANNER_RECV.
My code looks like
error = libssh2_init (0);
...
error = mTCP->Bind(ownip, mPort);
...
error = mTCP->Connect(mProxyIp, mProxyPort);
...
error = ProxyConnectCommand(mTCP, ip, port, mProxyUser, mProxyPassword);
/* HTTP CONNECT method */
...
mSession = libssh2_session_init();
...
/* Since we have set non-blocking, tell libssh2 we are blocking */
libssh2_session_set_blocking((LIBSSH2_SESSION *)mSession, 1);
error = libssh2_session_banner_set((LIBSSH2_SESSION *)mSession, "SFTP
Client\r\n");
...
#if LIBSSH2_VERSION_NUM >= 0x010208
/* correct method since libssl 1.2.8 */
error = libssh2_session_handshake((LIBSSH2_SESSION *)mSession,
mTCP->GetSocket());
#else
#endif
At this last libssh2_session_handshake call I get the -2 error code:
My Log looks like:

Any hint ?
