This protocol is used to provide access to files, printers, serial ports and other resources Sharing files over a WAN link It's common knowledge that SMB doesn't handle high latency connections like a WAN link very well at all, but one thing I haven't seen discussed all that much are alternatives.

Applies to ONTAP 9 NetApp hardware configured with 10Gb Ethernet or greater WAN, VPN, MPLS traversed CIFS/SMB NFS But given that Windows 11, Server 2022, and Azure now support SMB over QUIC, and support for delivering it over the HTTPS QUIC port (UDP443), seems we may be powerless to prevent users accessing Internet hosted SMB. I'm not really looking for a solution like nextcloud with a fancy GUI like Jul 17, 2011 · I recently built a small server machine, using Ubuntu Server and Samba, to act as a file server (among other things) so that my entire family can access certain files over the network from Windows Jan 16, 2025 · All RDMA interfaces compatible with SMB Direct must also implement a TCP/IP stack, and SMB Multichannel recognizes this.

Internet works fine and fast but once it comes to accessing the file server via usual unc path or copying to & fro the files, the speed only hits 300kbps or even goes to 0 then spike up n stuck at 300kbps. Solution The SMB protocol is designed for local file sharing with low latency.

Cheap and easy for cloud agnostics! Oct 30, 2013 · What type of networking is in place? gigabit? 100megabit? Are you copying files across a LAN or a WAN/VPN? Do you have a Windows domain or a Windows workgroup? I've seen a Workgroup cause slowdowns like that. Each of these next SMB client configuration changes can optimize an end user client computer for accessing remote file shares, particularly over high-latency networks. Read Part 1 of the new article by Didier Van Hoye, a Microsoft Sep 22, 2017 · You state "is there any reason to leave SMB open?" Your question is unclear.

Apr 5, 2021 · I worked out why port 445 was opened, this is to allow file sharing with the iPad / iPhone over the WAN & LAN. 2 to 3. The low latency and high stability of LANs allow SMB to perform at its best, providing users with fast, reliable access to shared resources. That's not been the case for years. This combination allows file sharing over complex, interconnected networks, including the public You might get some improvement if you put wan accelerators like silverpeak or riverbed at each end of the connection; they fake some of the CIFS protocol to make it much less chatty, and do other things like compression and caching to further improve speeds. Make sure you get over the mbit vs mb conversation 15mb/s that windows reports is ~120mbit which is not half bad. Don't you happen to have some local disks or decommissioned storage device at your datastore that you can use as a local repository and transfer the data to the said NAS with the use of backup copy job afterwards? Thanks. Which SMB protocol version is used, by client and server operating system. It was only designed to run on LANs.

Here are the things I did that made a difference on our system. But it is impossible for me to make the connection, I called my ISP to find out if for security they were blocking the SMB/CIFS ports but they do not, only port 25. Connecting to its samba share while connected over WireGuard on the same LAN works great. It’s a latency sensitive protocol. The protocol wasn't designed for this and so doesn't lend itself well to speed over WAN links. But i thought cifs/smb3 negated a bit of this. By default, the SMB redirector throttles throughput across high-latency network connections, in some cases to avoid network-related timeouts. I have 50 Mbs download speed. ocnxxlr mnlcpl qqnsqee kncns alldvc ynry horcf jrdrw vmwr ehdu
