[Samba] getpeername failed. Error was Transport endpoint is notconnected (3.0.37)

[Gaiseric Vandal]

I find I have to have both ports open-  then again my main samba servers are
configured as DC's.   I don't know about member servers, but DC file server
are using SMB-over-NetBIOS-over-IP  (NT4 style) -   I don't think they can
support pure SMB-over-TCP/IP.  I had tried setting to 139 only-  I think
some XP and Win 7 clients make an initial connection to port 445 then get
redirected.

If I disabled Netbios on the XP clients, they can't connect to a samba DC.

This error is very old, and seems to be related to samba binding to multiple
ports (139 and 445).  You only need 445 in most modern worlds, unless you're
a PDC from what I can tell.  I stuck this in my smb.conf file:

# restrict ports to avoid
# "getpeername failed. Error was Transport endpoint is not connected" and
# "Error writing 4 bytes to client. -1. (Transport endpoint is not
connected)"
# errors from port 139 legacy mode - PDC may need 139 open
        smb ports = 445
