Barry, I think your message got garbled, as evidenced by the runs of commas and the semicolon. But what I did try was to add the ip4 hosts, which had not been in the /etc/hosts file created by Fedora13. I can see what you're saying by also adding servername.domainname, but I'm not sure what to put there, because the server and terminal are both a router, hence the 192.168.1.103 IP address. Anyway, here's what I tried, with the same result. LTSP boots fine, but users trying to login keep betting kicked out to the login prompt. 192.168.1.103 orpheus # Added by NetworkManager 127.0.0.1 localhost.localdomain localhost localhost4 localhost4.localdomain4 orpheus ::1 orpheus localhost6.localdomain6 localhost6 (the localhost4 line above is wrapping in my mailer.

If your servername is server1 and your domain name is domain1 your 127.0.0.1 line should look like this. 127.0.0.1 localhost.localdomain localhost server1.domain1 server1 Reboot server. Try an TC login after this. See what happens. Are you able to vnc into this server from any machine on your network? Doesn't make any difference if it is windows or a linux machine. You do have the default vnc server setup via ltsp,correct? Do you have iptables stopped also? Can root log into a thin client successfully? Do the following two commands . nmap localhost nmap -sU localhost, at the server console and copy/paste both outputs here on the list to see what you have. Let us know.

I have listed the results below. I hope something below clicks. I am certain this is the result of one tiny setting, but the question is, which one?

Try an TC login after this. >See what happens. > No change after reboot. Note that there really isn't a correct hostname.domainname for the server. This is because it's a home internet connection where the router is directly connected to the service provider. So the name in the hosts file above really refers to the router. The router forwards port 22 to the server, so it is possible to ssh to the server from the outside world. The server has a single NIC and an ltsp bridge, the latter automatically created by LTSP. There is no internal DNS, so the server itself doesn't really have a name, other than orpheus.localdomain, which is already in the file. The static IP address of the server (192.168.1.103) is in the dhcpd.conf file. I have used this dhcpd.conf file successfully with LTSP under Fedora 11. The problem arose when I did a clean install of F13 and then installed LTSP. ----------------------------------------------------------- >Are you able to vnc into this server from any machine on your network? >Doesn't make any difference if it is windows or a linux machine.

One, I've found sometimes that disabling IPv6 helps. I was always told that 127.0.0.1 should only be localhost, and never the actual machine name; that is reserved for an addressable IP. I don't think the two things above account for your trouble though. Exactly how is your network set up? It sounds like you are trying to do this with only one NIC. There are instructions on the wiki about this, but it's definitely more complex that just using a second NIC. Network Manager should not have control over the interface that is bridged. Did you create virtual NICs out of your one NIC?

You are using an unmanaged switch in your setup? In other words a cheapo plug n play 10/100/(1000) switch. I am trying to picture your setup? You have a dsl into your home with a provided router. Your server is plugged into one of the lan ports, the TC is plugged into another lan port ,correct. Nope ,I just thought, this can not work. You are *only* seeing a class C ip address? hhhmmm 1a. do 'ifconfig' and copy/paste back the response. 2. I wasn't clear enough. Can root log into the server * from a thin client*. Not ssh. 3. I see that tcp 7100 is not listening. This is usually the case although I am not familiar with ltsp5 so this may not be necessary now. 4. It appears your ISP is setting the correct setting into your resolve file for 127.0.0.1 as it is listed now. 5. Run the command 'hostname' and report back what the response is. 6. Open a terminal (as root) and do a ' tail -f /var/log/messages' . After you have the terminal open,try logging into the server from a thin client. Copy/Paste about the last 100 lines into a message here. Maybe something will pop out of what is happening here. Report back. Good luck.

As I say, the client clearly finds the image, so I would think that means that the networking end of things is good, and the image boots properly, and we get the login screen, but after userid and password are entered, it returns to the login screen. Maybe it's something to do with ldm, although that doesn't seem well documented, so it's hard to make guesses. >1a. do 'ifconfig' and copy/paste back the response. eth0 Link encap:Ethernet HWaddr 00:1E:8C:68:38:D7 inet addr:192.168.1.103 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::21e:8cff:fe68:38d7/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:543342 errors:0 dropped:0 overruns:0 frame:0 TX packets:602301 errors:0 dropped:0 overruns:0 carrier:11 collisions:0 txqueuelen:1000 RX bytes:305945407 (291.7 MiB) TX bytes:639198479 (609.5 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:105465 errors:0 dropped:0 overruns:0 frame:0 TX packets:105465 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:105169058 (100.2 MiB) TX bytes:105169058 (100.2 MiB) ltspbr0 Link encap:Ethernet HWaddr 62:4C:94:CF:5C:15 inet addr:172.31.100.254 Bcast:172.31.100.255 Mask:255.255.255.0 inet6 addr: fe80::604c:94ff:fecf:5c15/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:2588 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:793267 (774.6 KiB) > >2.

On my system, dhcpd, dhcpd6 and dhcrelay are all disabled. ltsp-dhcpd is shown as enabled. I would expect the messages to say 'ltsp-dhcpd', but that's what I got. So in these messages, we see the requests from the thin client as it gets an IP address, and downloads the image.

Maybe it's something to do with ldm, although that doesn't seem well documented, so it's hard to make guesses. >1a. do 'ifconfig' and copy/paste back the response. eth0 Link encap:Ethernet HWaddr 00:1E:8C:68:38:D7 inet addr:192.168.1.103 Bcast:192.168.1.255 Mask:255.255.255.0 inet6 addr: fe80::21e:8cff:fe68:38d7/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:543342 errors:0 dropped:0 overruns:0 frame:0 TX packets:602301 errors:0 dropped:0 overruns:0 carrier:11 collisions:0 txqueuelen:1000 RX bytes:305945407 (291.7 MiB) TX bytes:639198479 (609.5 MiB) lo Link encap:Local Loopback inet addr:127.0.0.1 Mask:255.0.0.0 inet6 addr: ::1/128 Scope:Host UP LOOPBACK RUNNING MTU:16436 Metric:1 RX packets:105465 errors:0 dropped:0 overruns:0 frame:0 TX packets:105465 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:105169058 (100.2 MiB) TX bytes:105169058 (100.2 MiB) ltspbr0 Link encap:Ethernet HWaddr 62:4C:94:CF:5C:15 inet addr:172.31.100.254 Bcast:172.31.100.255 Mask:255.255.255.0 inet6 addr: fe80::604c:94ff:fecf:5c15/64 Scope:Link UP BROADCAST RUNNING MULTICAST MTU:1500 Metric:1 RX packets:0 errors:0 dropped:0 overruns:0 frame:0 TX packets:2588 errors:0 dropped:0 overruns:0 carrier:0 collisions:0 txqueuelen:0 RX bytes:0 (0.0 b) TX bytes:793267 (774.6 KiB) > >2.

I have an idea that you will not really want to try, but since it is somewhat amusing, I will share it. I needed to do this very thing once, so I took an old computer fan, taped a circular piece of cardboard to the blades to make it into a crude turntable. Then I laid it on its side on the table, put the mouse on the platter, and plugged it in. It worked!

A quieter alternative might be Homer Simpson's idea with the drinking bird: http://en.wikipedia.org/wiki/Drinking_bird but I'm hoping for a solution that doesn't require fans, cardboard, a drinking bird, mouse or keyboard!

It has to be something wonky in ssh or pam rules. Note: Usually if the ssh part on ltsp/k12ltsp is hosed the TC should get a message "You are not authorized to connect to the server" which you are not seeing,which is strange? Check these out. 1.Drill down to . /opt/ltsp/i386/root/.ssh Make sure you are seeing two files id_rsa and id_rsa.pub . Make sure the dates on each are matching each other. Next as root do the following in a terminal: chmod og-rwx /opt/ltsp/i386/root/.ssh/ chmod og-rwx /opt/ltsp/i386/root/.ssh/id_rsa chmod og-rwx /opt/ltsp/i386/root/.ssh/id_rsa.pub 2. Look in /home/johndoe/.ssh/ See if johndoe has the same two files,(id_rsa and id_rsa.pub) as you seen in the ltsp/.ssh tree (dates) If this looks hunky dory. 3.

Clean install of LTSP on Fedora 13 using the RPMs from Gavin's site and the instructions on the wiki. 2. Added users and created new home folders for them. 3. When they try logging in graphically on the server, it works just fine, but they are unable to log in from the thin clients when the login screen comes up? One network question, isn't the IP of the LTSP bridge a 172. address? not a 192.168.1? Per the wiki, your eth0 card shouldn't have it's own IP, and it shouldn't be managed by NetworkManger. It's being tied to bridge br0, which LTSP sets up as having a private 172. address system.

You should be receiving"This workstation is not authorized to connect to this server" error if in fact it is ssh related. You did say you updated FC13 after initial install,so more than likely the running kernel got updated in the process. Try booting from the original kernel of FC13 one time and try logging into the server from an TC. At the Fedora splash screen tap space bar,> Arrow up,> press ENTER. If you still receive the same errors / can not connect to server from TC,you will know that it is related to your client install of ltsp and not the actual server libs. Beings you are running 64 bit there could be some behind the scenes snafoo's in the update process,that haven't got uncovered yet. Also read through the install wiki again and make sure your nic bridge setup is correct as Burke mentioned. I don't think Network manager should be involved,although the client is downloading the kernel,the ltsp side may get confused behind this. See if you get any different results.

Getting LTSP 5 to work on Centos 5 was difficult if not impossible because Centos 5 just doesn't have all of the necessary pieces built in. Gavin, who also works for RH I believe, is trying to pick up where Warren left off.

I managed to get LTSP working in F13 and published the .rpm's as well. https://bugzilla.redhat.com/show_bug.cgi?id=598134 The big issue now is the Major changes in F14 are causing some issues trying to get LTSP working @ all. I am still working on this and have a friend who is also trying to help, But we are both also swamped with workloads that seem never ending. I aim is to have my .rpm's in the Official F13 Repos very early next year. and then work on seeing *if* LTSP will ever work on F14/RHEL6/CentOS6. We do have some Bugzilla's open for the work. So as soon as things calm down here @ work, I will get strait back on the LTSP Train. > (It would be nice if RH could offer official, paid support for LTSP > on RHEL 6, although I realize the business case may just not be > there.)

K12LTSP is one of the better things I've spent time with in my life. It bettered the life of hundreds of school kids that I was involved with and saved my wife's practice a lot of time and money. I still think LTSP or the similar concept is an extremely viable concept and has more uses than most people imagine.

Quite sometime back I was told by a gentleman that has run his own business his whole adult life,and a very smart person in every way,and is a World traveler. He told me the United States would be the last country to ever 'flip' to Linux as the US is so commercial driven. He is a Linux guy,merely as a hobby as well.That sounds so simple but I find this statement true in every way on lots of things. K12LTSP included. Everyone always asks me first question." How to do they do it for free"??..They are skeptical at this point,huh? Very much the same as the old saying if you are trying to get rid of a liter of puppies. In the ad you run in the paper you always want to put $15 each on them. If you put them in the paper for free,no one will take them. ,,,:) Take Care, BC From lars.schade at berlin.de Sun Dec 12 14:56:49 2010 From: lars.schade at berlin.de (Lars Schade) Date: Sun, 12 Dec 2010 15:56:49 +0100 Subject: [K12OSN] Thoughts on K12LTSP fading into the sunset In-Reply-To: <4D02046E.7080703@redhat.com> References: <1291930701.17923.31.camel@localhost.localdomain> <4D017B91.3000106@scheie.homedns.org> <4D02046E.7080703@redhat.com> Message-ID: <1292165809.3635.21.camel@localhost> Gavin, thanks for being so clear about the near term prospects of k12linux. Though just like many others I am left disturbed and worried about the future of LTSP on RH/fedora. I was expecting to be on the save side with RHEL6 since it is based on f12/f13. And now you put into question whether LTSP will ever work on RHEL6/f14. That leaves us with just a 6-month perspective of f13 as I understand. Could you possibly point out just very briefly what the technical hurdles in RHEL6/f14 are? Just so we get a feeling for whether it is a general incompatibility (also applying to f15/f16...) or more of a change requiring a though major but one-time modification to LTSP. Back in September things sounded very promising but since reading your recent mail I am really concerned about the future of LTSP in RHEL6/f14. But thanks again for the info, nothing is worse than planning on false expectations. -Lars Am Freitag, den 10.12.2010, 10:43 +0000 schrieb Gavin Spurgeon: > -----BEGIN PGP SIGNED MESSAGE----- > Hash: SHA1 > > On 10/12/10 01:00, Peter Scheie wrote: > > I think Warren is still working for Red Hat, but is busy with other > > things.

Why? Because it works, no fuss, no muss. For me, there's currently no compelling reason to upgrade. There's a company in Texas that, to my knowledge, is still running K12LTSP 5EL for their business. It does a great job. Not everybody needs the shiny new features of LTSP 5. For these folks, LTSP 4 really continues to do a fine job. That said, LTSP 5 would be pretty cool to run, no doubt. --TP Julius Szelagiewicz wrote: > I have been running LTSP 4 for ever now, as I can live without the new > stuff (business setting makes it easier) and I can say that LTSP 4 works > just fine with RHEL6.

It has something like 6G of ram compared to 2G on its replacement, and a massive SATA drive vs a tiny IDE. The clients will remain unchanged - 10 year-old Gateways with 256M RAM. We have six of these. A parent at our school donated the server. He was inspired to do this because late last year the students had prepared some ooimpress presentations, and had ten of them running on the six terminals (four of them were minimized). It was dismal. I don't think that a new server was the solution, but he could not be dissuaded. My guess is that running OOo on the clients would be a better approach to solving the bottleneck. The network is 100Mbit, via an unmanaged switch. I plan to bring the new server online over the Christmas break. Is it possible to set this up for running an app locally with EL5? I am terrified of upgrading to something newer, especially in light of the age of the thin clients. What should I do with the old server?

Does that also include the connection to your server? About 6 years ago, I had a dual-Athlon MP, 1.4GHz box with 3.5GB DRAM serving 24 clients daily, with simultaneous OpenOffice.org and Firefox sessions open (school computer lab), and that server had no problems with it. Response (for that era) was snappy, and the K12LTSP server was not overloaded. The difference was that I had a Gig-E connection to the server. Never, ever say no to a more powerful box! I envy you. :-) If that server has built-in Gig-E, which I suspect it does, then make sure you have a Gig-E port on whatever switch you're connecting it to. This is, as Joe Biden would say, a big...umm...deal. :-D Seriously, though, this is. The clients can be 100Mbit, no problem, but the server should hook up to Gig. I'm assuming that the CPU's are also more powerful than your current server. Is this is 64-bit server, perchance? If so, then you can run 64-bit K12LTSP 5EL on it, but there are a few things to be aware of, especially with regard to Firefox and plugins. Let us know, and again, congrats! --TP j.w. thomas wrote: > I've been running a K12LTSP 5EL for a couple of years, and have just > been donated a newer server.

Even if You have to buy a cheapie 4 port switch to get the extra needed ports in the given room it is going into. I REALLY wish the school here had ALL HP printers. USB printers setup easily in K12LTSP now but networked printers just make them so much more versatile, in my findings anyway. If you have never looked much at the HPLip package for Linux you should before you purchase your printers. This makes admining any HP printer very slick ,into one interface. All your maintenance can be done remotely without having to walk the printers and all from one interface,not httping to each web gui. This package has matured very nicely to were almost any HP printer is supported,even very late release models.

In-Reply-To: References: Message-ID: <4D14CC36.3040604@bittware.com> When I bought our printer, I focussed almost entirely on the cost of the consumables. Having been stung by the cost of inkjet carts in the past, we went for a B&W laser, as it had the lowest care and feeding cost. Unfortunately, my focus on that aspect was not sufficient. It had been so long since I had run into anything that would not work under Linux that the thought that such things still exist never entered my head. I ended up getting a Canon, and yes, it is a winprinter. I didn't find that out until after the toner cart was opened, which was the point of no return. So now I'm stuck with a Canon. I had to cobble together a Win2K box to be the print server. It is very much Rube Goldberg contraption, and I cannot wait until the day that printer accidentally falls off the table and is irreparably damaged. Learn from my fail.

In-Reply-To: References: Message-ID: even though the cartridges for a laser are out rageous the cost per print is less than half the inkjet per page and I often will just go to the printer settings page in Open Office or the printer setup and set it for B&W except when actually printing color which helps keep the cost down by only using the Black cartridge.

I didn't look deep enough if this gives the hardware compatibility listing by numbers? I know there is a page for this somewhere. I have found that if you hand install the latest tarball almost any hp printer to date will be supported,though. The Centos 5 rpm's for hplip may not contain the driver for your latest,greatest color printer,though. Have a look see what you can come up with. Let us know what you end up purchasing. https://launchpad.net/hplip Take Care, Barry From microman at cmosnetworks.com Sat Dec 25 20:51:29 2010 From: microman at cmosnetworks.com (Terrell Prude' Jr.) Date: Sat, 25 Dec 2010 15:51:29 -0500 Subject: [K12OSN] Colour Inkjet Printer Recommendations?

It's very important to first un-install the stock RPM that comes with CentOS 5. It's not hard to install the new one, and I've got to give HP credit here. They're doing a bang-up job of supporting their devices with Free Software. --TP Barry Cisna wrote: > Joseph, > > Below is a link to the hplip project. It is working today?

The difference in speed between this and a thin client is beyond noticeable. Here are the parts I used: Foxconn A74ML-K 3.0 Socket AM3/ AMD 740G/ A&V&GbE/ MATX Motherboard MB-A74MLK3 $43.99 Evercase E0526-S15 150W Mini-ITX Case (Black) CA-0526S15 $45.90 $45.90 AMD Athlon II X2 Processor 250 (3.0 GHz) AM3, Retail ADX250OCBX $62.99 $62.99 Super Talent DDR3-1333 2GB Original Memory D32G1333SP $18.98 $18.98 Sub Total $171.86 I ordered from SuperBiiz, but you could probably get similar pricing from NewEgg or TigerDirect. Last I checked, those two didn't carry the case, however, and the case is a really nice, small case for a client. With a micro-ATX mobo, there's only room for a slim optical drive and a 2.5 inch hard drive, so if you're not using either of those, you're not wasting a lot of room. Also, there's a vent just over the location of the CPU, so the CPU fan blows right out of the case. Since there's no case fan, that's a pretty good thing. There are still a couple of things I'm not sure about with using a fat client with Ubuntu LTSP. I changed /etc/environment, but it doesn't seem to show up when people log in, and I did have to create a way for network traffic to get forwarded, but other than that, the set-up is very nice. It's not super low power, but the CPU is about 65 watts and the motherboard doesn't use much more. Obviously, you could get a nice thin client that uses much less power, but I don't think it would be as fast, and it might not be much smaller.
