SAMBA:password chat problem
by SuSE 10 Nov '00

10 Nov '00

I'm trying to synch my Win and Linux passwords but I'm having problems debugging my passwd chat. I'm using SuSE 6.3. with my Linux box as a domain master. All passwords are encrypted. smbpasswd is populated Win password caching is off(relevant?) Initial logon Ok and shares accessible. This is what I see when I use passwd at the console. (The following done as root) >passwd sand New password: New password (again): Password changed smb.conf contains passwd program /usr/bin/passwd %u passwd chat *New*password* %n\n *New*password* %n\n *changed* unix password sync Yes log.smb contains Invoking '/usr/bin/passwd sand' as password change program. talktochild: chatbuf=[*New*password*] responsebuf=[New password: ] talktochild: sendbuf=[sandstorm ] talktochild: chatbuf=[*New*password*] responsebuf=[New password (again): ] talktochild: sendbuf=[sandstorm] talktochild: chatbuf=[*changed*] responsebuf=[] [2000/11/10 09:40:08, 3] smbd/chgpasswd.c:talktochild(266) response 3 incorrect [2000/11/10 09:40:08, 3] smbd/chgpasswd.c:chat_with_program(316) Child failed to change password: sand Thanks in advance for any suggestions.

SAMBA SWAT
by SuSE 10 Nov '00

10 Nov '00

James By default samba uses plaintext passwords. The newer flavours of Win (and NT) encrypt their passwords resulting in what your experiencing (I too was caught out..for many fruitless hours!) There are solutions You can hack the Win registry (on every machine that is to access samba) so that it uses plaintext passwords or you can amend samba config to use encryption. This involves creating and populating a smbpasswd file(separate to the normal passwd file) Have you allowed the SWAT service on port 901 in your services file. It was not enabled by default on my system (SuSE 6.3) Hope this is some help Mike Rees Mike Rees Systems Manager Ysgol Glanymor School Heol Elfed Burry Port Llanelli SA16 0AL Tel 01554 832507 Fax 01554 832424 mike(a)glanymor.carms.sch.uk

Hi Kevin Thanks for the continued useful comments Its probably only my impatience to get things moving that is causing me problems. When you only sitting at the Linux machine in snatched moments between lesons its difficult to build up any sort of momentum However... Things seem to be progressing. I installed Tera Term Pro on the PC and managed to TelNet to the server (including changing back up to su(root). I fiddled round with smb.conf directly and managed to get a share appearing in Networkwork neighbo(u)rhood but it doesn't seem to like my passwords...?!!! I think you are right about the Netscape problem with localhost:901. When the ISDN lead was plugged in it took me onto the web???!!!!! Maybe I'll know more when I run ifconfig tomorrow James Carter p.s yes reply was supposed to go to list so here it is below if it helps any other newbies out there. p.p.s Just received copy of Running Linux BOL was cheapest online (£19 inc p&p) > > > > I haven't run the suggested commands yet but I know the ISDN card and > > ethernet card are installed and recognised. > > Thats the first stage then.

XDM-X Term mini howto has been updated ...
by kevin.taylor＠powerconv.alstom.com 09 Nov '00

09 Nov '00

Thought some of you may be interested to know that the XDM/X Terminal mini Howto has been updated. I have revamped some of the wording to make things (hopefully) a little clearer. I have also started a section describing common configurations and updated the references. Thanks to everyone who commented on the first version. As always comments are welcome on this new one too. See : http://www.linuxdoc.org/HOWTO/mini/XDM-Xterm/index.html Ta, Kevin.

This is very good advice - thin Ethernet, just don't go there. we had it here on our admin net, yep it's cheap, but you get what you pay for - trouble! It took lots of tweaking before it settled down. We have a Gb back bone and loads of flashy kit here (had to sweet talk the bursar and hassle several firms (all out of favours with the bursar now!)), but at one of our feeder schools I have set up a 10 machine network with patch leads, a couple of palm hubs (dirt cheap) and some sticky back trunking. It works well enough at 10Mz If you can't do it, most local PC shops will make leads to any length - The usual max length of a patch lead is 10M (this is laid down in the CAT5 Spec - Does anyone know if this is different for CAT5E or CAT6 ?) If you can find a local firm who will 'fluke' your system for nothing, go for it. If you KNOW that the cabling is sound, it will cut down the time it takes to diagnose any faults. You don't need any unknowns! :-) PS if you have any crossover leads, make sure that they are clearly labeled as such, otherwise they WILL trip you up in the future.

> However, if thin ethernet avoids needing a hub, this > may be viewed more favourably by my budget-holding bosses! Thin ethernet is a pain - which is why people are chucking it out (bend the cable a few times and you could bring down the whole network). UTP would be the way to go. You could start with 2 nodes talking point to point, using a UTP cross-over cable (ie no hub would be required). Eventually, you need to either : - Plug into your existing hub(s) - Buy a new hub to plug into your existing hub I would recommend staying with the type of kit you already use (assuming that it is ok) - it just simplifies things in the long run. Let us know when you get things hooked together, and we can chat again ... Kevin.

I'd personally attempt to avoid thin ethernet (10Base2 - which is 50 ohm co-axial cable with locking BNC connectors on the end - similar but not the same as TV co-axial and the cable is very different electrically so *never* attempt to use TV cable for this). 10Base2 works fine when it works... when theres a problem its very difficult to isolate just where the problem is - a single poorly wired connector can make a machine at the other end of the cable misbehave for example. Basically 10Base2 is unsupportable in a hostile environment - such as a school :-) You can get 10/100BaseT PCI cards (twisted pair cabling with RJ45 plugs on each end - RJ45 are 8 way plugs made of clear plastic with a central locking clip on the opposite side of the plug to the connectors. They are similar to BTs phone plug but not the same or interchangable) for a cost of less than 10 pounds per card. Choose your cards relatively carefully as some types are more supportable and reliable under linux than others (I would give a specific card recommendation but I don't have web access right now). These cards have 100BaseT capability which might be useful later You need a hub for more than 2 10/100BaseT devices. Cost of this is roughly the same per-port as cheap cards. Unfortunately for your 25 machines thats looking like around 500 pounds plus the cable itself. BTW for those just setting up a small network, with ISDN network access, look carefully at the small office networking kit - ie DLink 206 ISDN router, which does DHCP and provides external access etc and has an embedded 10BaseT hub for just over a hundred quids.

> Now what do I do? :o) I am not quite sure how far you have got ? Do you have a physical network installed ? Do you have a working IP network between the machines ? Have you looked at Samba yet ;-) These are the 3 stages - let us know where you are, and we can take them one at a time. >From your comments, I think you are at the first - if so, what type of physical network connection do you have on your cards ? Twisted Pair ? (Phone type sockets on the cards) Thin ethernet ? (BNC connectors on the cards). For twisted pair, you need a TP hub (approx 30 to 50 quid for a cheap one with 4 to 8 ports). For thinnet, you need lengths of thin ethernet cable and 2 terminators. Many places are throwing out thin ethernet and replacing it with twisted pair - so depending on your level of playing, and how much money you want to spend right now - you may be able to pick up some thin ethernet - or alternatively, invest in a hub - but we need to know what sort of network cards you have installed. Books to consider : Network Administrators Guide (LDP and ORA book) Samba (ORA book - also available online). Ethernet Howto (LDP) See http://www.linuxdoc.org/ http://www.ora.com/ Kevin.

Anyone using ROX filer
by Colin McQueen 09 Nov '00

09 Nov '00

Hello I am an ICT Co-ordinator (ex network manager) at The Romsey School. We use Linux for web serving and proxying but its RedHat. I'm testing the SUSE 6.4 at home before swapping over to using that instead of RH6.1. I have installed ROX filer on it so we get a RISC OS look alike filer. Its pretty good and I feel more comfotable with its drag and drop interface. Has anyone else tried this or need help doing so ? Its available via :- http://rox.sourceforge.net/ Cheers -- Colin McQueen : Using an Acorn StrongARM Risc PC Web Domain : http://www.mcqueen.uk.net/ BSc Zoology + Oceanography : PGCE : MSc in CBL/T
