Be clever with linux permissions - use features like SGUID (chmod 2xxx folder) and also your smb.conf settings for the share: force group = pupils This will mean that you can then assign permissions to selected groups with considerable ease. Check that the users are also members of additional groups as appropriate. Hey presto. RE: hiding shares from view ... Make sure the shares on the linux box (apart from netlogon) are marked browseable = no They do not then show in the output of net view or the windows explorer etc. netlogon is a special case, which must be left browseable, or all your clever policy thingies wont be found correctly. Incidentally, you do not *have* to put them in netlogon. You can make a new share, whose name *can* end in a $, leaving the share effectively hidden. You then need to update the registry on the work stations to do a *manual* download of the policy (look in the default machine settings via policy editor, after electing to view the registry). Ensure this holds the UNC path to the config.pol file (including the file name), e.g. \\server\hidden$\config.pol. Leave error checking on until you have got it working. If you need more info, I can probably go more into chapter and verse.

Group Policies
by Alex Brett 29 Jan '02

29 Jan '02

>From the info I've got it appears that group policies dont work under samba as samba doesnt tell the windows clients which is the primary group for a user. I've found a way round it using a separate netlogon folder for each group and then having a separate config.pol - however, i occasionally need to add certain computer records to the policies, and if i had to do this i would have to go through every config.pol which will take a while, and also, bearing in mind i am likely to have about 100 groups! If anybody knows of a patch or anything else to fix this, I would be very grateful! Alex Brett alex.brett(a)brettcomputers.co.uk

The reason that this is happening is *because* you have share permissions set to "Everyone". Change them to "Domain Users" instead of "Everyone" and this will resolve the problem - since your server will then require an authenticated account for access to those shares. It won't however solve the issue of poor security due to badly configured permissions in the first place. The only way to fix this is the hard way - which you will still have to do if you use samba or upgrade to Win2K. Personally I'd save some money and a lot of hassle and fix the problem that you have, which isn't really that hard. Chris L

migrating from nt4 to linux
by Alex Brett 28 Jan '02

28 Jan '02

I help my old school out with their computers and i currently have a Win NT4 server with Win95 clients. I also have one Red Hat Linux 7.1 Server running Squid, DNS and NAT for the internet. I want to turn the Win NT4 server into another Linux server hopefully running a Red Hat or a Suse version. The system has to be able to cope with logins from Win 95 clients, deal with the profiles we currently use (a config.pol file in netlogon) and provide tight file security (something we currently do not have with NT4!). From my experiments with Samba I believe it can do this but is there anything important I should know. The network admin there is looking at Win2k but I want to provide him with reasons to go for linux. Also, as a side-point - is it possible to tie network cards together to provide greater bandwidth by doing load balancing or similar? Thanks in advance, Alex Brett alex.brett(a)brettcomputers.co.uk

Group Policies in SAMBA
by Paul Munro 27 Jan '02

27 Jan '02

I too have never gotten group policies to work under SAMBA. This is *probably* due to lack of knowledge on my part, but I too noticed lots of people with the same problem. I'm going to have another look at this and then see if there are any updates etc., but if anyone knows how to fix/do this I'd appreciate it also. Paul

Migrating From NT4 to Linux...
by Paul Munro 27 Jan '02

27 Jan '02

Yes. To all. And then some :-) As someone has said, place all of your config.pol into a Netlogon share, making SAMBA the domain logon server. You will need SAMBA 2.2.x but that shouldn't be a problem. As far as channel bonding goes, I looked into this some time ago and in theory it is possible but personally I never got to a solid conclusion about it. Remember, load balancing and channel bonding are two separate things, so make sure you are implementing the correct method! SAMBA/Linux as a server will exceed your expectations and security needs without a shadow of a doubt. You will have more granular security over files and file permissions, and looking through a book such as "Using SAMBA" by OReilley will help you with the subtle SAMBA configuration options that will secure your server from installation and early configuration (something you'll need being in a school I suspect). Good luck--let us all know how the decision goes and how the implementation goes!!! Paul

You (don't) got Mail
by Matt Johnson 26 Jan '02

26 Jan '02

Usually things seem to just work, or they don't. I could do with a hand here... I may have this all wrong - I've read the mail administrators howto, and the users howto and I'm a little stuck with an intermitant fault... I've set no mail options anywhere on my system. I have a cable modem with NTL. I'm trying to automate a mail message that, for example, mails me a directory listing from the current working directory. I type: ls -l | mail johnsonmlw(a)yahoo.com I was surprised to see it work at all. I was expecting to have to set some settings. BUT it only works about 1 in 10 times. Odd. If I type it ten times in quick succession, I only get about one into my johnsonmlw(a)yahoo.com mail box, and I receive nine returns from mx1.mail.yahoo.com reporting a "501" error - data format error. I'm a complete mail novice - I've always used my yahoo account. Any suggestions as to why it only sometimes works, and whether I should be typing something else? Thanks folks -- Matt __________________________________________________ Do You Yahoo!? Great stuff seeking new owners in Yahoo! Auctions! http://auctions.yahoo.com

linux stuff and databas
by Ron Johnson 25 Jan '02

25 Jan '02

Dear Hall We are a 200 strong(or weak) pupil primary school that's run a linux server for the past 4 years- which has never gone wrong (LEA told us it wouldn't work, after we installed they came down saw it, said it was great and then still told other schools won't work) We use very little of the SIMS package because its useless and the pupil data base we use is crap - its a great system - they give out updates (about 3 to 4 a year) that inveriably(or do I mean always) go wrong then over 300 school secretaries or adminstrators phone up and try to sort it out (superb way of employing people) I used to complain that the database, budget etc stuff was old fashioned - but at least in the old days the old systems worked - people like stuff if it works and saves them a job or gain some extra benefit - which SIMS etc doesnt Can we get something else? We have about 15 computers that will eventuallly (shortly) be Linux - although I have to keep Windows on for some learning software and games (yep A of E and we have playstations and gameboys - part of the curriculum old boy - games r good for kids - anybody that doesn't think so needs to play (work with) the games - comments/arguments welcome ho! ho!) recently set up Linux with three thin clients LTSP - guess what -Linux KDE desktop has worked out EASIER than windows for staff and children - more options and more user friendly stuff. It seems to be working great so far Can anybody give me some sites with good Linux software for education - I can't seem to find any - even off a CD if anybody knows of stuff. Thanks for listening (??) Ron __________________________________________________ Do You Yahoo!?

CCM Facility
by Mike Elliott 25 Jan '02

25 Jan '02

We are looking to deploy CCM's Facility timetable / scheduler next September which uses M$ SQL 7 as standard. Does any one out there use this software with a Linux DB, DB2 and Oracle are the most obvious. My manager is not keen on MYSQL, but if some one is using it for this successfully it might change his mind! Any information would be useful. Thanks in advance. Mike Elliott IT System Eng.
