Unhappy Samba Shares on Ubuntu 8.04 - Random Disconnects and Slow copying


ello - plez can anyone help?

I'm running Ubuntu 8.04 (2.6.24-21-generic) with Samba Version 3.0.28a.

It used to work fine until one day - not sure if I changed something; but the following symptoms started appearing.

I have both Windows 32bit and another machine with Windows 64bit - when I copy to the the linux fileserver the copy is extremely slow, but I have a gigabit network.

If I copy 5 files at the same time - all of a sudden, the copy speed significantly increases for all those files and more of the gigabit connection speed is used, but if I select five files at the same time copying it is very slow, becaue they are not copied in parrallel but in serial - that is, "one at a time".

Then also; let's say i'm busy with a large download from the internet - that file remains open on the server for the duration of the download; now if I sometimes (intermittently) access one of the fileserver shares to use another file from the fileserver; all the connections to the server disconnects and the downloaf fails because samba reports to windows that the file is no longer available; but if I press F5 to refresh the view in Windows - everything is back to normal.

Is anyone familiar with the problem that I'm having? plez

Summary -
1) Intermittent disconnects when accessing multiple files through Samba on a windows machine.
2) Extremely slow copy speed on a gigabit network!

If you need more information - I will gladly provide!

What kind of switches are you using? Try running wireshark and capture the data on the network from the machine that drops the connections. This will be a good start.
