I have an older server running Ubuntu where I have a few SMB shares. I also have a Mac. I have previously been using my SMB shares from my Mac without any problems.
Recently I had to reinstall Ubuntu on the server and while almost everything is up and running again I have some problems with my SMB shares.
Whenever I try to write to the SMB shares from my Mac the network on my Mac slows to the point where it almost dies.
I can read from them perfectly fine, and copy a file from the server to one of the shared folders on the server without problems. But whenever I try to copy something from my Mac it fails horribly.
I have tried just simple copy paste and using SFTP as well.
So something tells me it had nothing to do with my server, but something to do with my Mac.
I have read quite a few posts by now, which suggested checking stuff like the SMB version via
smbutil and disabling delayed TCP acks but so far nothing has helped.
I am not even sure what to look for/where to start.
