7. Problems running pppd 7.1 pppd says that version 0.0.0 is out of date. You are attempting to run the 2.2 pppd process and you haven't rebuilt the drivers in the kernel. 7.2 pppd says that that the kernel is not configured for PPP.
ml-ppp bundle dies if initial link fails (even in 2.4.7) Linux kernels from the 3.14 and 3.16 branches (3.14.19 and 3.16.3 at the moment) and pppd 2.4.6. However, pppd is heavily patched as we implemented Dial-on-Demand over ML bundles, which is not possible with the stock pppd. I'm afraid I haven't found the time yet to send the patches upstream :-/ But you can look into them by yourself: Currently, multilink PPP is only supported under Linux. Pppd detects that the link it is controlling is connected to the same peer as another link using the peer's endpoint discriminator and the authenticated identity of the peer (if it authenticates itself). The endpoint discriminator is a block of data which is hopefully unique for each peer. PPPD is the Point-to-Point Protocol daemon which is used to manage network connections between two nodes on Unix-like operating systems. It is configured using command-line arguments and configuration files .

ID: CVE-2020-8597Title: pppd EAP Processing Buffer Overflow Vulnerability (“Ghostcat”)Vendor: Multi-VendorDescription: pppd (Point to Point Protocol Daemon) is vulnerable to buffer overflow due to a flaw in Extensible Authentication Protocol (EAP) packet processing in eap_request and eap_response subroutines.

Linux and UNIX Man Pages. pppd(8) [redhat man page] PPPD(8) System Manager's Manual PPPD(8) NAME pppd - Point to Point Protocol daemon SYNOPSIS pppd [ tty_name ] [ speed ] [ options ] DESCRIPTION The Point-to-Point Protocol (PPP) provides a method for transmitting datagrams over serial point-to-point links.
Linux Tutorial - Using PPP and Linux This tutorial covers many of the common PPP configurations for connecting Linux to your ISP. Methods include raw pppd, vwdial, Linuxconf, the GNome control pannel for ifup and ifdown configuration and X-isp. The YoLinux portal covers topics from desktop to servers and from developers to users Setting up the PPP connection manually The second is the default route, (established by giving pppd the option defaultroute. This is the route that tells our Linux PC to send any packets NOT destined for the local Ethernet(s) - to which we have specific network routes - to the PPP server itself. Authentication with PPP - Linux Network Administrator's pppd then extracts the client hostname (c3po.vbrew.com) from the response and searches the chap-secrets file for a line matching c3po as a client and vlager as the server. The second line does this, so pppd combines the CHAP challenge and the secret arttoo! arttoo!, encrypts them, and compares the result to c3po ’s CHAP response.
