3. Common client questions

- -

3.1 Are there any Macintosh clients for Samba?

- -

- - -Yes! Thursby now have a CIFS Client / Server called DAVE - see -http://www.thursby.com/. -They test it against Windows 95, Windows NT and samba for compatibility issues. -At the time of writing, DAVE was at version 1.0.1. The 1.0.0 to 1.0.1 update is available -as a free download from the Thursby web site (the speed of finder copies has -been greatly enhanced, and there are bug-fixes included).

Alternatives - There are two free implementations of AppleTalk for -several kinds of UNIX machnes, and several more commercial ones. -These products allow you to run file services and print services -natively to Macintosh users, with no additional support required on -the Macintosh. The two free omplementations are Netatalk, -http://www.umich.edu/~rsug/netatalk/, and CAP, -http://www.cs.mu.oz.au/appletalk/atalk.html. What Samba offers -MS Windows users, these packages offer to Macs. For more info on -these packages, Samba, and Linux (and other UNIX-based systems) -see -http://www.eats.com/linux_mac_win.html

3.2 "Session request failed (131,130)" error

- -

- - -The following answer is provided by John E. Miller:

I'll assume that you're able to ping back and forth between the -machines by IP address and name, and that you're using some security -model where you're confident that you've got user IDs and passwords -right. The logging options (-d3 or greater) can help a lot with that. -DNS and WINS configuration can also impact connectivity as well.

Now, on to 'scope id's. Somewhere in your Win95 TCP/IP network -configuration (I'm too much of an NT bigot to know where it's located -in the Win95 setup, but I'll have to learn someday since I teach for a -Microsoft Solution Provider Authorized Tech Education Center - what an -acronym...) Note: It's under Control Panel | Network | TCP/IP | WINS -Configuration there's a little text entry field called something like -'Scope ID'.

This field essentially creates 'invisible' sub-workgroups on the same -wire. Boxes can only see other boxes whose Scope IDs are set to the -exact same value - it's sometimes used by OEMs to configure their -boxes to browse only other boxes from the same vendor and, in most -environments, this field should be left blank. If you, in fact, have -something in this box that EXACT value (case-sensitive!) needs to be -provided to smbclient and nmbd as the -i (lowercase) parameter. So, if -your Scope ID is configured as the string 'SomeStr' in Win95 then -you'd have to use smbclient -iSomeStr otherparms in connecting to -it.

3.3 How do I synchronise my PC's clock with my Samba server?

- -

- - -To syncronize your PC's clock with your Samba server: -

Copy timesync.pif to your windows directory
timesync.pif can be found at: -http://samba.org/samba/binaries/miscellaneous/timesync.pif
Add timesync.pif to your 'Start Up' group/folder
Open the properties dialog box for the program/icon
Make sure the 'Run Minimized' option is set in program 'Properties'
Change the command line section that reads \\sambahost to reflect the name of your server.
Close the properties dialog box by choosing 'OK'

- -Each time you start your computer (or login for Win95) your PC will -synchronize its clock with your Samba server.

Alternativley, if you clients support Domain Logons, you can setup Domain Logons with Samba -- see: -BROWSING.txt *** for more information.

Then add -


--NET TIME \\%L /SET /YES
-
-

- -as one of the lines in the logon script.

- -

3.4 Problems with WinDD, NTrigue, WinCenterPro etc

- -

All of the above programs are applications that sit on an NT box and -allow multiple users to access the NT GUI applications from remote -workstations (often over X).

What has this got to do with Samba? The problem comes when these users -use filemanager to mount shares from a Samba server. The most common -symptom is that the first user to connect get correct file permissions -and has a nice day, but subsequent connections get logged in as the -same user as the first person to login. They find that they cannot -access files in their own home directory, but that they can access -files in the first users home directory (maybe not such a nice day -after all?)

Why does this happen? The above products all share a common heritage -(and code base I believe). They all open just a single TCP based SMB -connection to the Samba server, and requests from all users are piped -over this connection. This is unfortunate, but not fatal.

It means that if you run your Samba server in share level security -(the default) then things will definately break as described -above. The share level SMB security model has no provision for -multiple user IDs on the one SMB connection. See -security_level.txt in -the docs for more info on share/user/server level security.

If you run in user or server level security then you have a chance, -but only if you have a recent version of Samba (at least 1.9.15p6). In -older versions bugs in Samba meant you still would have had problems.

If you have a trapdoor uid system in your OS then it will never work -properly. Samba needs to be able to switch uids on the connection and -it can't if your OS has a trapdoor uid system. You'll know this -because Samba will note it in your logs.

Also note that you should not use the magic "homes" share name with -products like these, as otherwise all users will end up with the same -home directory. Use \\server\username instead.

3.5 Problem with printers under NT

- -

- - -This info from Stefan Hergeth -hergeth@f7axp1.informatik.fh-muenchen.de may be useful:

A network-printer (with ethernetcard) is connected to the NT-Clients -via our UNIX-Fileserver (SAMBA-Server), like the configuration told by -Matthew Harrell harrell@leech.nrl.navy.mil (see WinNT.txt) -

If a user has choosen this printer as the default printer in his -NT-Session and this printer is not connected to the network -(e.g. switched off) than this user has a problem with the SAMBA- -connection of his filesystems. It's very slow. -
If the printer is connected to the network everything works fine. -
When the smbd ist started with debug level 3, you can see that the -NT spooling system try to connect to the printer many times. If the -printer ist not connected to the network this request fails and the -NT spooler is wasting a lot of time to connect to the printer service. -This seems to be the reason for the slow network connection. -
Maybe it's possible to change this behaviour by setting different -printer properties in the Print-Manager-Menu of NT, but i didn't try it yet.

3.6 Why are my file's timestamps off by an hour, or by a few hours?

- -

- - -This is from Paul Eggert eggert@twinsun.com.

Most likely it's a problem with your time zone settings.

Internally, Samba maintains time in traditional Unix format, -namely, the number of seconds since 1970-01-01 00:00:00 Universal Time -(or ``GMT''), not counting leap seconds.

On the server side, Samba uses the Unix TZ variable to convert -internal timestamps to and from local time. So on the server side, there are -two things to get right. -

The Unix system clock must have the correct Universal time. -Use the shell command "sh -c 'TZ=UTC0 date'" to check this. -
The TZ environment variable must be set on the server -before Samba is invoked. The details of this depend on the -server OS, but typically you must edit a file whose name is -/etc/TIMEZONE or /etc/default/init, or run the command `zic -l'. -
TZ must have the correct value. -
1. If possible, use geographical time zone settings -(e.g. TZ='America/Los_Angeles' or perhaps -TZ=':US/Pacific'). These are supported by most -popular Unix OSes, are easier to get right, and are -more accurate for historical timestamps. If your -operating system has out-of-date tables, you should be -able to update them from the public domain time zone -tables at -ftp://elsie.nci.nih.gov/pub/. -
2. If your system does not support geographical timezone -settings, you must use a Posix-style TZ strings, e.g. -TZ='PST8PDT,M4.1.0/2,M10.5.0/2' for US Pacific time. -Posix TZ strings can take the following form (with optional -items in brackets): -
```
-        StdOffset[Dst[Offset],Date/Time,Date/Time]
-
```
  - -where: -
  - `Std' is the standard time designation (e.g. `PST'). -
  - `Offset' is the number of hours behind UTC (e.g. `8'). -Prepend a `-' if you are ahead of UTC, and -append `:30' if you are at a half-hour offset. -Omit all the remaining items if you do not use -daylight-saving time. -
  - `Dst' is the daylight-saving time designation -(e.g. `PDT'). - -The optional second `Offset' is the number of -hours that daylight-saving time is behind UTC. -The default is 1 hour ahead of standard time. -
  - `Date/Time,Date/Time' specify when daylight-saving -time starts and ends. The format for a date is -`Mm.n.d', which specifies the dth day (0 is Sunday) -of the nth week of the mth month, where week 5 means -the last such day in the month. The format for a -time is hh:mm[:ss], using a 24-hour clock.
  - -Other Posix string formats are allowed but you don't want -to know about them.
-

- -On the client side, you must make sure that your client's clock and -time zone is also set appropriately. [I don't know how to do this.] -Samba traditionally has had many problems dealing with time zones, due -to the bizarre ways that Microsoft network protocols handle time -zones. A common symptom is for file timestamps to be off by an hour. -To work around the problem, try disconnecting from your Samba server -and then reconnecting to it; or upgrade your Samba server to -1.9.16alpha10 or later.

3.7 How do I set the printer driver name correctly?

- -

- - -Question: -On NT, I opened "Printer Manager" and "Connect to Printer". -Enter "\\ptdi270\ps1" in the box of printer. I got the -following error message: -


--     You do not have sufficient access to your machine
-     to connect to the selected printer, since a driver
-     needs to be installed locally.
-
-

- -Answer:

In the more recent versions of Samba you can now set the "printer -driver" in smb.conf. This tells the client what driver to use. For -example: -


--     printer driver = HP LaserJet 4L
-
-

- -with this, NT knows to use the right driver. You have to get this string -exactly right.

To find the exact string to use, you need to get to the dialog box in -your client where you select which printer driver to install. The -correct strings for all the different printers are shown in a listbox -in that dialog box.

You could also try setting the driver to NULL like this: -


--     printer driver = NULL
-
-

- -this is effectively what older versions of Samba did, so if that -worked for you then give it a go. If this does work then let us know via -samba@samba.org, -and we'll make it the default. Currently the default is a 0 length -string.

- - -

3.8 I've applied NT 4.0 SP3, and now I can't access Samba shares, Why?

- -

- - -As of SP3, Microsoft has decided that they will no longer default to -passing clear text passwords over the network. To enable access to -Samba shares from NT 4.0 SP3, you must do ONE of two things: -

Set the Samba configuration option 'security = user' and implement all of the stuff detailed in -ENCRYPTION.txt.
Follow Microsoft's directions for setting your NT box to allow plain text passwords. see -Knowledge Base Article Q166730
