If that is the entire output, not only is nothing listening on port
135, Samba doesn't seem to be listening at all, is it running ?

That is the entire output;  samba is not listening.

It is started.

Any idea why "smb" is not an invalid service?

Can you post your smb.conf, perhaps that will explain why smbd isn't
being starting.

We no longer include the ntvfs file server (that is what 'smb' referred
to, it is a historical oddity from before the 4.0 merge) in the default
build.  If you are using bind9, set:
 server services = -dns
if you are not usind bind9 for DNS, remove 'server services'.

Likewise remove any dcerpc endpoint services line. 

Samba will refuse to start up if the smb.conf referred to invalid or
not-built components. 

Finally, in case this is how it happened, never use the output of
testparm -v as an smb.conf file, please only specify options you need
to change, so when we change the defaults you don't need to know about
it.

Thanks,

Andrew Bartlett
