similar to: Multichannel working at half speed with 2x NICs

Hi Jeremy, Is it safe to assume it's just "strace -p <pid>", for the running samba daemon?

Sorry for the delay Jeremy. I ran strace on the lowest pid for smbd (I ran "pidof smbd" to get pids, and used the lowest one of the 4 or so that came up). Command was "strace -f -o strace.log `ls /proc/2019/task/ | xargs -n 1 echo -n " -p`". I then copied a 1.3GB file from the server to my client to generate traffic. The resulting file was around 93k lines (15MB).

That's not the one you need to strace: you need to find out which smbd process belongs to your session (with

Hi, In our samba3 days, we provided a homedirectory like \\filehost\username. Now, with samba4 / ADUC using "\\filehost\username" gives the error: "the home folder could not be created because: the network name cannot be found". We have a little root preexec scripts creates the directory and sets permissions, so ADUC only needs to accept the

Hello, I'm running Samba 4.4.5 with enabled SMB Multichannel. The Linux server has two 1GBit/s NICs and for testing purposes I've shared a tmpfs mountpoint with 2GiB and ~2GiB large test-file. My Windows 10 host has one dual-port 1GBit/s NIC, and if both interfaces are enabled, Get-SmbMultichannelConnection lists active multichannel connections to my Linux SMB server. If I disable one

Hi guys, I have configured gluster fs in replication mode in two ubuntu servers. Windows users use samba sharing to access the mounted volume. Basically my setup is that client machines on each site connect to its local file server so it has the fattest connection. Two files servers are connected via VPN tunnel which has really high bandwidth Right now it is very slow to write files to the

Hi! I am trying to enable multi-channel when the NIC support RSS(Receive Side Scaline) . I use tcpdump and wireshark to record packet that send by smbclient and windows 11 client. There is no multi-channel phenomenon when using smbclient, but when using the windows client, I observed that the samba server opened an extra port to transmit data. I think this is the phenomenon of multi-channel

Hi. I have two servers located in two different time zones. I want to know if there is a way to keep the shares synchronized. Right now what i thought is to run rsync from Server A to Server B . However the issue is say Server B has a new version of the file in server A and that should not be overwritten but should be copied back to server A. How to go about this? Regards Janantha

Hi, I'm going classicupgrade our samba3 to samba4 next weekend, and suddenly realised something: I intent to keep my samba3 PDC machine called 'filehost' as a member server, to only serve files. However, after classicupgrade my new (freshly installed) DC1 will of course have the netbios name from my 'old' samba3 machine. ('filehost') Meaning I end up with two

https://bugzilla.samba.org/show_bug.cgi?id=5124 --- Comment #12 from Paulo Marques <paulo.marques at bitfile.pt> --- Using multiple connections also helps when you have LACP network links, which are relatively common in data center setups to have both redundancy and increased bandwidth. If you have two 1Gbps links aggregated, you can only use 1Gbps using rsync, but you could use 2Gbps if
