Introduction ; The Linux bonding driver provides a method for aggregating multiple network interfaces into a single logical “bonded” interface. The behavior of the bonded interfaces depends upon the mode; generally speaking, modes provide either hot standby or load balancing services. Additionally, link integrity monitoring may be performed. The bonding driver originally came from Donald Becker’s beowulf patches for kernel 2.0. It has changed quite a bit since, and the original tools from ...
2. Configuring the kernel ; Be sure to turn on the following options: ; if you want to try out router support (not properly debugged yet) you’ll need the following options as well… ; Don’t turn on SIOCGIFCONF support for DECnet unless you are really sure that you need it, in general you won’t and it can cause ifconfig to malfunction.

Retrieve the sources of the Linux version you intend to build; then change into the directory holding them, as all further commands in this guide are meant to be executed from there. ; First, execute the following command to retrieve a fresh mainline codebase: ; If you want to access recent mainline releases and pre-releases, deepen you clone's history to the oldest mainline version you are interested in:
Feature name, Status ; Dialects, Supported. SMB2.1 SMB3.0, SMB3.1.1 dialects (intentionally excludes security vulnerable SMB1 dialect). ; Auto Negotiation, Supported. ; Compound Request, Supported. ; Oplock Cache Mechanism, Supported. ; SMB2 leases(v1 lease), Supported. ; Directory leases(v2 lease), Supported. ; Multi-credits, Supported. ; NTLM/NTLMv2, Supported. ; HMAC-SHA256 Signing, Supported. ; Secure negotiate, Supported. ; Signing Update, Supported. ; Pre-authentication integrity, Supported. ; SMB3 encryption(CCM, GCM), Supported. (CCM/GCM128 and CCM/GCM256 supported) ; SMB direct(RDMA), Supported. ; SMB3 Multi-channel, Partially Supported. Planned to implement replay/retry mechanisms for future. ; Receive Side Scaling mode, Supported. ; SMB3.1.1 POSIX extension, Supported. ; ACLs, Partially Supported. only DACLs available, SACLs (auditing) is planned for the future. For ownership (SIDs) ksmbd generates random subauth values(then store it to disk) and use uid/gid get from inode as RID for local domain SID. The current acl implementation is limited to standalone server, not a domain member. Integration with Samba tools is being worked on to allow future support for running as a domain member. ; Kerberos, Supported. ; Durable handle v1,v2, Planned for future. ; Persistent handle, Planned for future. ; SMB2 notify, Planned for future. ; Sparse file support, Supported. ; DCE/RPC support, Partially Supported. a few calls(NetShareEnumAll, NetServerGetInfo, SAMR, LSARPC) that are needed for file server handled via netlink interface from ksmbd.mountd. Additional integration with Samba tools and libraries via upcall is being investigated to allow support for additional DCE/RPC management calls (and future support for Witness protocol e.g.) ; ksmbd/nfsd interoperability, Planned for future. The features that ksmbd support are Leases, Notify, ACLs and Share modes. ; SMB3.1.1 Compression, Planned for future. ; SMB3.1.1 over QUIC, Planned for future. ; Signing/Encryption over RDMA, Planned for future. ; SMB3.1.1 GMAC signing support, Planned for future.

If you find yourself craving more bandwidth, and have a ISP that is flexible, it is now possible to bind modems together to work as one point-to-point link to increase your bandwidth. All without having to have a special black box on either side. The eql driver has only been tested with the Livingston PortMaster-2e terminal server. I do not know if other terminal servers support load- balancing, but I do know that the PortMaster do ...
