What steps will reproduce the problem?
1. connect to network via ethernet , wifi or gsrm
2. make sure you can ping the vpn router
3. make a pptp vpn connection

or run from console
mtpd pptp xx.xx.xx.xx 1723 "linkname vpn name xxxxx password xxxx" &

What is the expected output? What do you see instead?
should see a connection made
running logcat we see

Please provide any additional information below.

Added code to pptp.c in external/mtpd
to display sizeof(address)
size of address returned from connect(pppox,
is = 14.

code below

static int create_pppox()
{
    int pppox;
    log_print(INFO, "Creating PPPoX socket");
    pppox = socket(AF_PPPOX, SOCK_DGRAM, PX_PROTO_OPNS);

    if (pppox == -1) {
        log_print(FATAL, "Socket() %s", strerror(errno));
        exit(SYSTEM_ERROR);
    } else {
        struct sockaddr_pppopns address = {
            .sa_family = AF_PPPOX,
            .sa_protocol = PX_PROTO_OPNS,
            .tcp_socket = the_socket,
            .local = local,
            .remote = remote,
        };
        if (connect(pppox, (struct sockaddr *)&address, sizeof(address)) != 0) {
            log_print(FATAL, "Connect() %s", strerror(errno));
            log_print(FATAL, "CONNECT address size %d", sizeof(address);
            exit(SYSTEM_ERROR);
        }
    }
    return pppox;
}

Looks like a problem in connect(pppox,

I have found the answer to this problem. This goes all the way back to the master branch and was introduced by changes made in 2009 (FROYO) PX_PROTO_OLAC and PX_PROTO_OPNS in the Bionic / libc /kernel / linux chain do not match those in the kernel / include chain!!! Sloppy Coding and/or checking TI and/or rowboat if you want help from a very senior special projects engineer on patching this code. please email me with instructions to post or submit to your GIT: Please for give my Sloppy comment, but I have coded to the DOD-2167 standard all of my carrier.
