From ngaywood at une.edu.au Thu Mar 1 02:19:46 2012 From: ngaywood at une.edu.au (Norman Gaywood) Date: Thu, 1 Mar 2012 13:19:46 +1100 Subject: [K12OSN] ldm login and password that starts with '@' Message-ID: <20120301021946.GA988@turing.une.edu.au> Just found an interesting bug in ldm. If you type @ as the first character of the password, the enter key does not work. The password of @guest@ or @backend@ will allow the enter key to work again but the login screen will just go back to the user prompt. This of course will stop people having @ as the first character of their password. Here is the code from ldmgreetercomm.c that I think is going wrong: int listen_greeter(gchar **buffer, gsize *buflen, gsize *end) { while (1) { /* Reads data from I/O channel of the greeter */ GError *ge = NULL; if(g_io_channel_read_line(greeterr, buffer, buflen, end, &ge) != G_IO_STATUS_NORMAL) { log_entry("ldm",3,"%s", ge->message); return 1; } g_strstrip(*buffer); log_entry("ldm",7,"Got command: %s",*buffer); /* handle callbacks */ if (**buffer == '@') { if (!g_strncasecmp(*buffer, "@backend@", 9)) { ldm_raise_auth_except(AUTH_EXC_RELOAD_BACKEND); } else if (!g_strncasecmp(*buffer, "@guest@", 7)) { ldm_raise_auth_except(AUTH_EXC_GUEST); } continue; } break; } return 0; } I think that continue should not be there. -- Norman Gaywood, Computer Systems Officer University of New England, Armidale, NSW 2351, Australia ngaywood at une.edu.au Phone: +61 (0)2 6773 3337 http://mcs.une.edu.au/~norm Fax: +61 (0)2 6773 3312 Please avoid sending me Word or PowerPoint attachments.

Hmmmmmm....32bit 64bit combo issue? What happens if you add rdshell parameter to kernel load? Honestly have not tried installs using latest centos but should be simple. Do check paths in the scripts as these change from version to version. Try ubuntu? -------------- next part -------------- An HTML attachment was scrubbed...

A couple days ago,,on a fairly new install of CentOS 6.x / SL6.1 ltsp5, I was adding three usb printers for three TC's. Later that afternoon all TC's on this server would fail on boot,,at "dracut: starting plymouth daemon". I had also updated several packages on the server itself as well. I didn't know if possibly a server package had caused something to change in a conf file for whatever reason? After many attempts to pinpoint the problem, I reinstalled ltsp-server. Of course this ploped a new lts.conf file into place. Now the TC's once again bootup as expected. In hindsight I should have known the prob was in fact the lts.conf file. I had edited the file in Webmin editor. I was able to reproduce the problem again be editing the lts.conf file in the same manner(after saving a backup).The file itself appears to be correct in the format. If I done a side by side file compare with meld,using webmin on one,and vi on the second they compare identical,although the webmin edited file kills the TC's booting. All i can figure is a white space is placed in the file,,maybe? Ownership,and perms looks identical. >From now on I will take the extra time to edit with vi.

If you want to find out if that's it, open it with vi, and then type ":ff=dos" and then save the file. That will save the file with line endings instead of the more compact unix-ish .. Not all programs can parse alternate line endings properly (parsing text is /hard/). To change the 's back to just 's again, open it with vi and type :ff=unix then save. If you ever open a file in vi and a lot of ^M's show up, that means it has mixed line endings.

Maybe possible end of line terminator differences? Sometimes vi will detect an correctly display DOS files (CR/LF). When you edit the file in vi look at the bottom line for [dos] when you open the file.

Unfortunately, its an existing server with spare capacity...can't reinstall it...but can create a virtual machine with ubuntu.....but I assumed that since I did not know anything about ltsp/pxe/tftp toolset....it would be more difficult to setup the ltsp server in a virtual machine.

I found only the --arch and --release options....noting to specify the linux type Arch IS the linux type. I believe the options are i386(x86-32bit) or amd64(x86-64 bit) on SL. I think we used to have a ppc option back in the day. Maybe in the future it will support ARM? If you want to build an 32 bit client chroot but are running a 64 bit version of the OS on your server, you need to specify --arch -i386 when you run ltsp-build-client. The --release option lets you pick Fedora 11, 14, or SL (the default) for your client chroot. I'd use the default (SL/EL) chroot because it will be supported longer. PIII processors are i686 and should work just fine. The only reason to use F11 for a chroot is that some VIA and other processors on older thin clients are only i586 compliant, and are no longer supported SL6.x or Fedora 14 chroots. It's just there to support older clients. Fedora 14 was added as a chroot because it had better video card support that SL6.0, but I THINK SL6.2/EL6.2 has probably incorporated some of those drivers by now. > > I think I need a little clarity here...google too is not yielding much... > > Could you guys please advise?

Are you using NBD? If you are, you need to rebuild the image any time you change the chroot that the clients are booting from. It looks like a Fedora 11 kernel is being used to boot the client?

The problem that caused the lts.conf file editing to make the TC's unbootbale was in fact as Joseph had mentioned. All that was needed was to add an additional line break, AKA: ENTER after the last entry in the lts.conf file.

This is pretty straightforward, look at the existing URL in ltsp-i386.ks and replace as much of it as needed with the new url (which would be an HTTP mirror, and you can find a list of those at http://www.scientificlinux.org/download/mirrors).

Now I have a few questions. 1. On Ubuntu's LTSP setup, it was necessary to update the chroot. Is that needed in the Centos/Scientific Linux setup? There was a nice setup guide for Ubuntu (https://help.ubuntu.com/community/UbuntuLTSP/UpdatingChroot) which contained the basic idea. I thought about just doing this manually already, but then was worried about copying /etc/yum.repos.d -> /opt/ltsp/i386/etc/yum.repos.d because the LTSP image is running scientific linux and my repos would be CentOS? 2. When users log in (on the thin client) they are presented with the following prompt: "Authentication is required to set the network proxy used for downloading packages" Any ideas on removing this?

You will have to install VirtualBox (or something very similar). This works out very well for troubleshooting problems like you are having. Follow the instructions here. Once you have done this once or twice setting up an pxeclient VM,,is very easy. see if you get the same results on your VM pxeclient as you do your,'hardware clients'.

Did you do any entries on the server system-wide for entering a proxy number:port for using apt-get or yum by chance? I am not quite clear if you are at current running Ubuntu as the server side of your current ltsp install?

She cares about some web app she found that uses it. I've already taken the "no" path with Shockwave, and it did indeed make shock waves. I very nearly lost my LTSP install over it. If I keep saying "no" to everything she asks for, it will strengthen the position that "LTSP can't do everything I need." In other words, I could win all the battles and lose the war. I'm sure she will continue to find applications out there that require Shockwave, Silverlight, Windows, and who knows what else. I try to find replacements when I say no, but those are never as satisfying (to her) as saying yes. I want to reserve "no" for things that really can't be done.

I took Tom Hoffman's advice and installed it on my linux desktop, and tried the app she wanted to run. All it does is warn that this is SilverLight 4, and not all features will work. Even if it did work on my desktop, that is no guarantee that it would work with LTSP. So I am investigating alternatives.

I dont anticipate any issues getting them to work side by side. My goal right now is getting xdmcp working with ltsp5 and a sl6 root. ldm, telnet and ssh are fine. xdmcp dies. i mentioned my 4.2 root primarily to demonstrate a working kdm config. the host currently uses kdm and kde desktop. Do i need to use gdm ? xdm ? Does lts.conf require an xdm_server statement ?? does it need xfs on the host ? X :1 -query from TC shell gives the same error as a normal attempt to load x using xdmcp in lts.conf: FATAL: module fbcon not found XDMCP fatal error: Session Failed Session 340368001 failed for display lt01:5: cannot open display.

It really had nothing to do with video drivers, chipsets, ltsp-xorg.conf, etc. It seems that on cent6, if the host isnt running bind, or able to talk to another dns server, kdm has an issue performing a name lookup or reverse lookup and crashes, even if i have valid configs in hosts for host and TC. Oddly, kdm shows, in netstat, it has an established connection to an external dns server when host and tc are the only devices connected to a switch. I removed the default gateway, power cycled the TC and x came right up.

In this case, scope out the price of putting up a Windows terminal server (LTSP can do RDP), multiply that times however many servers you'll need (last I checked, WTS could only handle about 10 simultaneous sessions), plus the cost of the CAL licenses. It will quickly add up. Then you can say to the powers-that-be, "Yes, we could do that, but we'll have to cut a teacher or a few aides to pay for it, because proprietary software is always going to be expensive, sooner or later. Remember, MS is a *business* which means they are first & foremost interested in making money and that money comes from you. Linux & FOSS are about enabling people to do things; money usually isn't the concern." Then, if you've found an alternative that works on Linux, you can say so, and hopefully they'll be more receptive.

Many teachers are trying too hard to show improvement and they will lock onto to ANYTHING that shows promise. Sadly, the school process that teachers go through to qualify them for the job makes them totally unsuitable to do the type of evaluation required to determine if a particular tool, technology, or process has the effect they think it does. In other words, they are trying to do psychology experiments but have no scientific background or training in how to set upo and devise controls, etc. for any type of experiment. So the challenge for us tech geeks is we have to get them to explain what they are trying to do from a teaching standpoint, and we have to understand it. Then we have to go searching for tools that 1. run on our platforms 2. do what they think they need After nearly 10 years teaching college level physics and astronomy, the best technology is that which is invisible. Much of what I see being pushed at schools and teachers by vendors is the robotic teacher replacement drone garbage - practice drills with little to no knowledge enhancement. Invisible technology is like when looking for a specific TV program, they change the channel. The technology behind the process is "magic" yet accepted. Sadly, a teacher sees some web-based multimedia and because it "works" like changing the channel, the common assumption is the education process will also work the same. So by getting the teacher to do the evaluation of what that "tool the must have" really does, often they will find that a pencil and paper is more effective. I cringe daily looking at the text books my kids use in K12. Color and pictures take up money and space (which is money in publishing). Designing a book to have a full color picture on EVERY page doesn't encourage learning if the picture is not relevant to the text on the page. So the books got huge and very expensive and now they are causing back pain in kids who have text book based homework every night in every subject. A 65 pound kids can't carry a 30 pound book-bag. A web video can be informative but must be used in the context of other solid instructional methods. Migrating from paper to e-book will certainly make carrying the contents easier but the educational content is being diluted by the publishers. It makes the school district book review committee happy to see books, electronic or dead tree, with the important word highlighted and a per chapter glossary and a short chapter summary. Too bad that crap eliminates ALL of the student's learning process as they no longer have to figure this out on their own. The open text books group is doing it (mostly) right. The tech part still missing is an easy to use tool for student annotation of the PDF files that is transportable (i.e. their notes can "stick" with the PDF version and can be easily transferred to someone else). Tablets are nice but a tablet with a pen is even better. The ability to highlight a word or sentence or add a personal definition or reference in the margin will make the open text books better than the dead tree texts. The will make them belong to each student. If there is a way for the teachers to review the student's notes in their books and add extra comments, etc, wow! personalized teaching at the K12 level. -- -- James P.

That could be verified by using a live cd. When trying to delete files with funny characters, it is often easier to do using a GUI file manager.

I did try using a couple live cd's ,both Centos 6 and a deft CD( which I have found usually mounts LVM disks R/W easily). Unfortunately I got the same 'permission denied" when trying to delete the files using this method? I also tried the method of deleting the file by the inode number. Strangely enough,,I get no errors,and also I never get asked to confirm to actually delete the file. The command completes,,but the file(s) are not deleted. Nothing shows up in system log either FYI.This method did not work either. One thing I did find by accident when I try and create a blank file regardless of method,I always get error" bad file descriptor" when actually saving the blank file into either one of the two rootkit dirs. I am not sure what this represents. Almost as though these dirs are mounted in some fashion although,I see nothing in mtab or fstab? This is very strange to say the least. It is almost as though the immutable bit is set on these files,and dirs,,when in fact this is not the case.

It can identify many Linux root kits. That helps a lot in setting the next steps. I expect the rm command is compromised on the machine itself. Very strange the live CD's failed to be useful. They are self contained and should let you mount and attrib and rm all you like. Note: if you turn off ssh, you can't remote back in. The trick is to keep ssh updated (and any parts it depends on), deny root ssh connection, requires ssh keys (very, very secure) and block password access.

Or just do what you really should do when a system gets rooted: re-install it. Personally, I'd be most concerned with finding the initial attack vector. Every time we've dealt with a system intrusion before, we always discovered how they got in in the first place. Usually it's compromised account credentials (read "passwords") that came from either other systems or a successful phishing campaign. Turning off SSH should not be your ultimate solution for network security. Did the attackers brute-force your root password? Or did they find some remote vulnerability? If you don't know, to me that's even more reason to re-install the system, possibly with a newer release. I've been very happy with my LTSP install on RHEL6 and that's rather easy to keep up to date. -Josh -- --------------------------------------------------------- Joshua Malone Systems Administrator (jmalone at nrao.edu) NRAO Charlottesville 434-296-0263 www.nrao.edu 434-249-5699 (mobile) BOFH excuse #266: All of the packets are empty --------------------------------------------------------- From cisna-barry at wc235.k12.il.us Wed Mar 21 12:20:49 2012 From: cisna-barry at wc235.k12.il.us (Barry Cisna) Date: Wed, 21 Mar 2012 07:20:49 -0500 Subject: [K12OSN] file attributes Message-ID: <1332332449.6944.26.camel@wc19.wc235> Hello All, I did try the dd if,,, of as suggested in a post to change file size,,etc. After doing this routine i still get 'permission denied,,when trying to delete each file after the convert.
