[Samba] File transfer corruption (NULL characters)

Thu Jan 16 18:50:03 GMT 2003

I had a problem that falls within the same scope as this.  It was between
2.2.7a, Tru64 5.1a and NT 4.0, where files above 4GB are corrupted from what
appears to be an addressing issue with the 64 bit file system on the Alpha
and the 32 bit file systems on the NT servers.  2.2.6 had a different issue
so I ended up going all the back to 2.2.1 and that solve the problem for me.
Not a direct fix for your problem, but just a heads up that you may have
issues if you go too new.

Subject: [Samba] File transfer corruption (NULL characters)

I've got a couple of Solaris 7 boxes that are running samba 2.2.0. When 
I try to copy text files from a windows 2000 client to the server, the 
resulting file is filled with all NULL characters. I tried copying the 
same file to a NT server's share and there was no corruption.

When copying to the solaris share, the windows 2000 client eventually 
gives the following error:

      The specified network name is no longer available

The servers actually work great when I'm on the local network or running 
over a PPP dial up. The problem only occurs when I'm on the network via 
a VPN connection (Permit/Timestep client running over a PPPOE DSL 
connection).I know that this is probably a problem with the VPN client 
or possible the network but I'm pretty stumped. I have no idea where to 
go next. Any help or insight would be greatly appreciated :)

Here's the relevant log with the debug level set to 3:
