[Samba] Error was Transport endpoint is not connected

[Daniel Müller]

This message only says: I established to one of the ports 139 or 445
and dropped the other.
It is nothing to trouble about.

Betreff: Re: [Samba] Error was Transport endpoint is not connected

By default samba listens on two TCP ports-  445 and 139.  You can 
specify this in smb.conf

         smb ports = 445 139


445 is the newer smb  over tcp.    139 is the older smb over netbios 
over tcp/ip.       445 was for Windows 2000 and newer clients..  I am 
not sure why samba enables 445 by default since as far as I know it does 
not support smb-over-tcp (without the NBT/netbios over tcp stuff.)    If 
you  set "smb ports = 139" in your smb.conf you should see endpoint 
messages disappear.

I think what happens is Win 2000 (and newer)  clients will initially try 
to connect on port 445, find it isn't really compatible, and then "dump 
down" to NBT on port 139.

So your NAS may be occasionally connecting on port 139 without problems 
and occasionally connecting on port 445, and which point it fails.

OR-  the "endpoint" errors may be completely unrelated, but you just 
don't look for when when the NAS is working.


Is the NAS part of the domain?  Is it a windows or linux/samba based device?

My samba server is a PDC.  XP clients in the domain connect with no 
problems regardless of  if smb ports is 139 only or 139 + 445.   XP/Win7 
clients NOT in the domain can't connect to shares if 445 is disabled, 
which indicates they are connecting to 445 1st.
