[Samba] disabling version number

[Florian Effenberger]

Hi Jerry,

thanks for the reply, that's exactly what I meant. :-)

I know security by obscurity isn't good, but may I suggest a new option in
the smb.conf file, something like

version_string = "Samba %s"?

Thanks,
Florian

You mean here?

  $ smbclient -L shaggy -N
  Anonymous login successful
  Domain=[VALE] OS=[Unix] Server=[Samba 2.2.8]
                                  ^^^^^^^^^^^

You'll have to patch the code.  See smbd/reply.c:
reply_sesssetup_and_X() (line 1090)

  /* it's ok - setup a reply */
  if (Protocol < PROTOCOL_NT1) {
    set_message(outbuf,3,0,True);
  } else {
    char *p;
    set_message(outbuf,3,3,True);
    p = smb_buf(outbuf);
    pstrcpy(p,"Unix"); p = skip_string(p,1);
- ->  pstrcpy(p,"Samba "); pstrcat(p,VERSION); p = skip_string(p,1);
    pstrcpy(p,global_myworkgroup); unix_to_dos(p); p = skip_string(p,1);
    set_message(outbuf,3,PTR_DIFF(p,smb_buf(outbuf)),False);
    /* perhaps grab OS version here?? */
  }





cheers, jerry
