I have done this in the past but was quite some time ago. After getting everything redirected in regards to wires,and power cycling the modem(left coax/power disconnected for 5 mins),the server would not pull an public ip via dhcp. Tried crossover cable even,,no joy. I even tried my trusty Asus Netbook with FC10/k12linux,and it would not get an ip address either. As soon as I plug the linksys back into modem,it gets the (new) public ip,and of course then the k12ltsp server gets the internal ip ,no probs. Also rebooting the netbook into windows and plugging into modem it would get an ip no probs. I did call the cable company to ask if there was a known problem with possibly MTU size or something,quirky,but of course no one had any insight. I do not have an extra modem to try to see if possibly it is a firmware issue as I have read that cable companies do push out firmwares for modems on their networks(This is my own modem). Is this legal?...:) I did do the arp clear thing on each machine,and in fact a couple times when doing a service network restart got a seg fault on the ifup-eth script.Ive never seen this happen before. Also the network gui after the nic times out throws a strange error saying "i.p.a.d sent 4 packets lost 4 packets 100% loss".It is a class C network ip address it is trying to ping? never seen that before,either. Any ideas? Sorry for long post.

I will call the cable co again to make sure the device beyond the CPE/modem does have to have an 'registered' state. I just assumed the modem/mac that was registered to the account was all that was needed. This does kinda make sense what you are saying,in that the ip address that the k12ltsp server bombs out on,is always a class C/internal network? I have even tried disabling nating/iptables at boot,but no difference. Very strange this even happens on a single nic fc10 Netbook as well. Only common denominator is these all gigE nics,but then again the netbook grabs an ip on winders? Just thought of something, I doubt this is the case as I have two different Linksys wr54g routers and they both grab an ip ,no probs. I do have ipv6 disabled as well. At least it is unchecked in the network gui. I did search the docsis forums as well and never really see anyone having this same snafoo. It seems so simple,that there oughta be a simple resolve:) This is a small mom & pop (small town) cable co so i am sure their resources are not real abundant.

It seems so simple,that there oughta be a > simple resolve:) You could try setting the router MAC address to match the one on the 'outside' computer NIC (most routers let you do this) and see if it gets an address. Then if it does, swap back to the direct computer connection. If that still fails, it must not be because of the MAC address difference. -- Les Mikesell lesmikesell at gmail.com From bmullan.mail at gmail.com Mon Apr 5 19:46:13 2010 From: bmullan.mail at gmail.com (brian mullan) Date: Mon, 5 Apr 2010 15:46:13 -0400 Subject: [K12OSN] K12OSN Digest, Vol 74, Issue 3 In-Reply-To: References: Message-ID: Since you took your w54g out ... you previously probably had a 192.168.x.x network behind the w54g you probably also had set you default gateway to point to the w54g's address (usually 192.168.1.1) the w54g probably already had your ISP (roadrunner, verizon whoever), DNS and DHCP server addresses If you hook all of that directly to your modem... you have to remember that as far as Cable Modem's go your Cable MSO usually only gives you 1 or 2 IP addresses and the cable modem gets 1. Usually that IP address gets assigned to the WAN side of your w54g and you NAT behind the 54g to get your 192.168.x.x addresses and your DHCP gets IP addresses allocated by the w54g. Have you checked whether you can even get an IP address from DHCP? Also a cable modem is not a router a w54g is. so if your ISP (Cable MSO) has say a 65.x.x.x net and your server is using a 192.168.x.x then they won't talk w/out a router to route between the two networks.

What I have tried: 1) Cloned MAC address of HFC/(cable mac) modem to server eth1, no luck. 2) Cloned MAC address of eth1 k12ltsp server to Linksys router router obtains ip address as expected from sb5120. 3) Made sure arp cache is cleared( This happens when eth1 is deactivated). One thing I noticed that is odd is,when the eth1 cat5 wire is plugged into modem the activity light is unlit. After activating the eth1 and goes through the trying to obtain IP address gyrations,and fails,the modem activity light stays lit. It appears at this point the SB5120 modem is hanged. Of course I do not have a spare/different modem to try with. The connection is rock solid with the Linksys modem attached,though. As I stated before the server always throws different errors each time after trying to obtain an ip. This a 3 year old modem and design wise I'm guessing 6-7 years old.

If you are interested in debugging, you might try doing a wireshark capture of the DHCP request/response from the router and server to see what is different. The easy way to do this would be to insert an old hub (that bridges all the ports) in the connection and use a different machine (so the interface is already active) to do the capture. If you have thrown out all your hubs, you can do the same with a managed switch that lets one port monitor another. -- Les Mikesell lesmikesell at gmail.com From joseph.bishay at gmail.com Thu Apr 8 02:33:52 2010 From: joseph.bishay at gmail.com (Joseph Bishay) Date: Wed, 7 Apr 2010 22:33:52 -0400 Subject: [K12OSN] Acer / nVidia ION video?

Still have not figured out this delema. Thanks Les,on the Wireshark thing. I was about burned out on jockeying wires around,:-)But by doing the Wireshark routine,I see that the nic was in fact using ipv6,even though it was disabled in the network gui. I also had disabled in the /etc/sysconfig file as well & still using ipv6?? Come to find out there are two lines you have to add in modprobe to disable inet6 on centos 5 at kernel level. OK, got inet6 disabled and still find that the server never tries to pull a dhcp from the cable modem/ISP router. Called Motorola and no help there as soon as you mention linux its shuffle off time. The cable co,,of course sees that the cable modem is online so that's all the further that convo goes,which is understandable. What I have surmised is that when plugging the cat5 cable into the modem from the eth1(/Broadcom bcm5751) there is never a link light,at the activity light on the modem until the nic is activated. This is not right I am sure(I think,,,:-) ) I tried an cross over just to verify it would not work as well,it didn't make a light either. It almost appears as the nic sees the modem as a "legacy device"? Another one of my wonderful theories is that most SOHO routers are still 2.4 kernel firmware to the best of my knowledge and maybe this is why the old trusty sb5120 negotiates fine with these routers which 99% of time is the standard home setup. Also wondering if possibly something quirky in the broadcom driver as i have read some weirdness with most any broadcom stuff in different scenarios. Bottom line this server grabs ip no probs on an ethernet to ethernet connection (at work, as well as the linksys router). I think Im going to spring for a docsis 3.0 modem and see what happens there. I have learned a lot about docsis specs etc,if nothing else. Sorry for long post!

Bottom line,She was the first to offer to do a 'complete reset on their end". The other times I had called the cable company each one simply said,we can 'see the modem is online', case closed. As soon as She reset the cache or whatever on the ISP end the k12ltsp server got an ip address in two seconds! I had tried cloning the wan mac of the router that was working to a laptop that triple boots FC10, XP, and Vista. It never would get an ip regardless of what OS I was trying to deal with? I am wondering if besides the mac address of the attached CPE to the modem possibly the host name of machine is cached as well,so people can not clone the mac? I had always thought as long as you was using the same modem what was behind it was irrelevant. Actually two of the techs at cable co told me exactly this, in previous calls,even after I had explained I was wanting to eliminate the Linksys router! This makes sense as to why when I Wiresharked the k12ltsp server doing the dhcp get routine there was absolutely no interaction going on. Wrong mac,, you're toast!! I was also concerned about my Vonage phone registering behind the k12ltsp/nat server but it linked up in 60 secs.

I want this because we have some kiosk type machines that are used maybe one day a week and I don't need them running the other 6 days. Something simple like: shutdown -P +720 should work, but no matter who I try to run that it never works. An ltsp-localapps script in selected user's ~/.config/autostart folder seemed to be the easiest and would not require client image changes, but since shutdown has to be run as root I didn't think this would work. If anyone knows a way to do this I would still like to hear it. Next I tried creating a script /opt/ltsp/i386/etc/init.d/auto-shutdown.sh to run the shutdown command, rebuilt the image and then added this: RCFILE_01=/etc/init.d/auto-shutdown.sh to selected client sections in the lts.conf file. Still no go. I know the lts.conf file and section are being read correctly because the autologin parameters I specify there are working. The only other option I considered is creating a separate image for the clients to run auto shutdown but that seems like far too much work for such a simple problem. Any other ideas how I can selectively auto-shutdown some clients?

You shouldn't really have to do any rebuilding of the /ltsp root image for what you are wanting to accomplish. I think if you run 1) A scheduled cron job for many,,or 2) make up a cron job for each tc,with the information provided in the following link you should accomplish what you are wanting to do. Simply run each cron job as root,and it should nix each tc into a shutdown... Sidenote: In order to make this happen the sure fire way to do it is to assign each tc an ip address, which I am sure you have thought of as is also explained in the link provided. There are some other good tidbits of info for configing TC's here as well. http://skolelinux.org/~klaus/newnotater_Sarge/x2685.html Let us know your progress!

It seems to go through all the possible default ones and just flashes like when there is a resolution issue -- never gets off the console screen into a graphical mode.

Sorry I didn't answer that part before. The machine doesn't have a CD drive (it's a tiny machine that snaps onto the back of LCDs) so I have not tried any other distribution. It comes preinstalled with only FreeDos so no Windows either.

My issue with cron is that it doesn't do things _after_ a certain amount of time, it does them _at_ a certain time. Since I don't know when a user will start using the system I can't pick a specific time to shut it down. The other problem of course is that cron jobs would happen to _all_ TCs and I only want to shut down a few. I have not tried the ALLOW_SHUTDOWN = Y thing, but I still can't see an easy way that I could know how long a client has been up from the server (which is where it appears you run ltspinfo). I also don't know what you mean by assigning each TC an IP address. I know _how_ to assign a static IP, but I don't understand how that would get me closer to a solution. Can you provide some more details?

I have not tried that driver out. I took a look at it briefly and it looks a bit daunting but I will see if I can follow the instructions.

I do not think that the script will work because it probes your hardware for a local chipset (in your server) in order to build/rebuild the kernel modules.

You may be far better off by downloading the Centos5/k12ltsp .iso's and doing your initial k12ltsp install this way. It is almost an 'out of the box/turnkey setup',were what you are doing is fine,if you have *plenty* of time to fiddle with things. Especially if you have older hardware to be using as TC's. Sounds like your internet connection is not real great but even at that it would be worth your time to download the(6) .iso images and be up and running with your tc's reliably. Here is the link to download the .iso's: ftp://k12linux.mesd.k12.or.us/pub/K12LTSP/5.0.0-32bit/iso/ Why don't you post up what you are going to be using as TC's and I am sure someone will give you tips on client setup,etc. Let us know how things are going!

Turns out the SUID thing does work -- I just typo'd my script when I tested it that way. That being said the man page says not to user SUID so what I ended up doing is this: 1. Install sudo in the chroot 2. Remove this line from /etc/sudoers since ltsp-localapps launched things do not have a TTY: Defaults requiretty 3. Add this line to /etc/sudoers: %users ALL=(ALL) NOPASSWD: ALL 4. Create a script somewhere accessible on the client (ex: ~/auto-shutdown.sh) which contains something like this: #!/bin/bash ltsp-localapps sudo /sbin/shutdown -P +720 5. Create a desktop file in the autostart directory for the desired user(s) (ex: ~/.config/autostart/auto-shutdown.desktop) which contains something like this: [Desktop Entry] Encoding=UTF-8 Version=0.9.4 Type=Application Name=auto-shutdown Comment=automatically power off thin client Exec=~/auto-shutdown.sh StartupNotify=false Terminal=true Hidden=false Note:This step works for XFCE. Not sure if all other desktop environments also work like this. 6. Reboot, login (or autologin in my case) and wait for shutdown!

One thing you could do as well is add in your script is like 'echo "shutting down in 60 seconds"' in case someone is logged on. There should be a pretty simple -s xxx before shutdown. This would at least be a feeble attempt 'legal/disclaimer' sort of thing from the user point of view.If there is any chance for someone to get mad using a computer,you'll be the one to hear about it,for the tc shutting down in the middle of typing a thesis,,,:) Are you doing like an auto 'turn-on' in the bios at hour x on these tc's by chance?

I have even changed the default LDM theme and it looks brilliant! But now, I have a small problem that my users upon logging in are not in the LTSP environment (the one in /opt/ltsp/i386). They are actually logged into the server environment. My server is running F13 and my thin client environment image is F12 (since the F13 ltsp enviro wasn't building and due to stability on the client). Anyway, everything seems to be working great on the client in spite of this. I do, however want my users to be using the proper environment, since my changes and customisations for that image needs to be replicated to the client, and obviously the users do not need all the services on the server's image. My question is how do I remedy this so that users login to the correct environment. The login screen is taken from /opt/ltsp/i386/usr/share/ldm/themes, but once the user logs in they have the F13 background and everything. It seems to me that the solution should be pretty easy, but I have not found much information on how to properly create user accounts. I have the users home directory mounted in /opt/ltsp/i386/home/username, so this part is working. ~Thanks for your help! ------------------------------------------------------------------------ Mathieu Pelletier Director of IT Development Theological College of Zimbabwe Tel: +263 9 287032/3 Ext: 214 mpelletier at tcz.co.zw www.tczonline.com Chat Google Talk: mkpelletier Skype: mathieu.pelletier -------------- next part -------------- An HTML attachment was scrubbed...

The applications that users run actually run on the server. The client environment is only used to *display* the applications that are running on the server. An LTSP client is sort of like a remote console. You can designate individual applications to be run locally on the clients, but this is not the default. If you truly want the clients to be running stand-alone environments, you might look at DRBL (Diskless Remote Boot Linux). But make sure your clients are up to the task.

One of the beauties of the LTSP environment is that if every student has an individual log in, they can change their background, their home pages, add icons to the desktop, choose their windows manager (KDE, Gnome, xfce if you've chosen to install them). Not having to restrict this and monitor technology actually frees an instructor up to focus on teaching technology rather than spend time monitoring it. If a kid messes up their Gnome configuration, delete the Gnome configuration file in their home folder and they're fixed. It took me a little while to adjust to the different way of thinking, but it was very freeing to me and my students. That's my opinion anyway.
