These really +should be incorporated in the main docs someday. + + +---------------------- +HINT: Always test your smb.conf with testparm before using it + +If your smb.conf file is invalid then samba will fail to load. Run +testparm over it before you install it just to make sure there aren't +any basic syntax or logical errors. + + +---------------------- +HINT: Try printing with smbclient first + +If you have problems printing, test with smbclient first. Just connect using +"smbclient '\\server\printer' -P" and use the "print" command. + +Once this works, you know that Samba is setup correctly for printing, +and you should be able to get it to work from your PCs. + +This particularly helps in getting the "print command" right. + + +---------------------- +HINT: Mount cdroms with conv=binary + +Some OSes (notably Linux) default to auto detection of file type on +cdroms and do cr/lf translation. This is a very bad idea when use with +Samba. It causes all sorts of stuff ups. + +To overcome this problem use conv=binary when mounting the cdrom +before exporting it with Samba. + + +---------------------- +HINT: Convert between unix and dos text formats + +Jim barry has written an excellent drag-and-drop cr/lf converter for +windows. Just drag your file onto the icon and it converts the file. + +Get it from +ftp://nimbus.anu.edu.au/pub/tridge/samba/contributed/fixcrlf.zip + +---------------------- +HINT: Use the "username map" option + +If the usernames used on your PCs don't match those used on the unix +server then you will find the "username map" option useful. + +----------------------- +HINT: Use "security = user" in [global] + +If you have the same usernames on the unix box and the PCs or have +mapped them with the "username map" option then choose "security = +user" in the [global] section of smb.conf. + +This will mean your password is checked only when you first connect, +and subsequent connections to printers, disks etc will go more +smoothly and much faster. + +The main problem with "security = user" if you use WfWg is that you +will ONLY be able to connect as the username that you log into WfWg +with. This is because WfWg silently ignores the password field in the +connect drive dialog box if the server is in user security mode. + +------------------------ +HINT: Make your printers not "guest ok" + +If your printers are not "guest ok" and you are using "security = +user" and have matching unix and PC usernames then you will attach to +the printer without trouble as your own username. This will mean you +will be able to delete print jobs (in 1.8.06 and above) and printer +accounting will be possible. + + +----------------------- +HINT: Use a sensible "guest" account + +Even if all your services are not available to "guest" you will need a +guest account. This is because the browsing is done as guest. In many +cases setting "guest account = ftp" will do the trick. Using the +default guest account or "guest account = nobody" will give problems on +many unixes. If in doubt create another account with minimal +privilages and use it instead. Your users don't need to know the +password of the guest account. + + +----------------------- +HINT: Use the latest TCP/IP stack from microsoft if you use Windows +for workgroups. + +The early TCP/IP stacks had lots of bugs. + +Microsoft has released an incremental upgrade to their TCP/IP 32-Bit +VxD drivers. The latest release can be found on their ftp site at +ftp.microsoft.com, located in /peropsys/windows/public/tcpip/wfwt32.exe. +There is an update.txt file there that describes the problems that were +fixed. New files include WINSOCK.DLL, TELNET.EXE, WSOCK.386, VNBT.386, +WSTCP.386, TRACERT.EXE, NETSTAT.EXE, and NBTSTAT.EXE. + + +----------------------- +HINT: nmbd can act as a "WINS" server + +By default SMB clients use broadcasts to find shares. Recent clients +(such as WfWg) can use a "wins" server instead, whcih reduces your +broadcast traffic and allows you to find names across routers. + +Just point your WfWg, Win95 and NT clients at the Samba box in the WINS option. + +Note: nmbd does not support all WINS operations. Anyone out there have +a spec they could send me? + +----------------------- +HINT: you may need to delete your .pwl files when you change password. + +WfWg does a lousy job with passwords. I find that if I change my +password on either the unix box or the PC the safest thing to do is to +delete the .pwl files in the windows directory. The PC will complain about not finding the files, but will soon get over it, allowing you to enter the new password. + +If you don't do this you may find that WfWg remembers and uses the old +password, even if you told it a new one. + +Often WfWg will totally ignore a password you give it in a dialog box. + +---------------------- +HINT: Using MS Access + +Here are some notes on running MS-Access on a Samba drive from Stefan +Kjellberg <stefank@esi.com.au> + +1. Opening a database in 'exclusive' mode does NOT work. Samba ignores + r/w/share modes on file open. + +2. Make sure that you open the database as 'shared' and to 'lock modified + records' + +3. Of course locking must be enabled for the particular share (smb.conf) + + +--------------------- +HINT: password cacheing in WfWg + +Here is a hint from michael@ecel.uwa.edu.au (Michael Simmons): + +In case people where not aware. There is a program call admincfg.exe +on the last disk (disk 8) of the WFW 3.11 disk set. To install it +type EXPAND A:\ADMINCFG.EX_ C:\WINDOWS\ADMINCFG.EXE Then add an icon +for it via the "Progam Manager" "New" Menu. This program allows you +to control how WFW handles passwords. ie disable Password Caching etc +for use with "security = user" + + +-------------------- +HINT: file descriptor limits + +If you have problems with the limits on the number of open files you +can edit local.h to fix it. + +-------------------- +HINT: HPUX initgroups() problem + +here is a hint from Frank Wales [frank@arcglade.demon.co.uk]: + +HP's implementation of supplementary groups is, er, non-standard (for +hysterical reasons). There are two group files, /etc/group and +/etc/logingroup; the system maps UIDs to numbers using the former, but +initgroups() reads the latter. Most system admins who know the ropes +symlink /etc/group to /etc/logingroup (hard link doesn't work for reasons +too stupid to go into here). initgroups() will complain if one of the +groups you're in in /etc/logingroup has what it considers to be an invalid +ID, which means outside the range [0..UID_MAX], where UID_MAX is (I think) +60000 currently on HP-UX. This precludes -2 and 65534, the usual 'nobody' +GIDs. + +Perhaps you could suggest to users that, if they encounter this problem, +they make sure that the programs that are failing to initgroups() be +run as users not in any groups with GIDs outside the allowed range. + +This is documented in the HP manual pages under setgroups(2) and passwd(4). + + +--------------------- +HINT: Patch your SCO system + +If you run SCO Unix then you may need to get important TCP/IP patches +for Samba to work correctly. Try + +Paul_Davis@mindlink.bc.ca writes: + + I was having problems with Accpac using 1.9.02 on SCO Unix. One + posting function reported corrupted data. After installing uod385a, + the problem went away (a restore from backup and then another + run-thru). + + It appears that the uod385a update for SCO may be fairly important for + a lot of different DOS and Windows software under Samba. + + uod385a can be found at ftp.sco.com /SLS/uod385a.Z and uod385a.ltr.Z. + + |
