AV on Linux is largely about protecting your organisation's email recipients from forwarded attachments. Personally I would ensure your mailserver has AV, both incoming and preferably outgoing. I would also block all the obvious file types, largely because I don't trust ClamAV. ClamAV has never been that great, hardly ever detects even obviously viral mail attachments. But you could run ClamAV on LTSP as well, possibly overnight on /home as a warning system, I doubt it will find much though. You could also set something up to auto-scan inserted USB keys. But after a while of running Linux, you do get a bit complacent about viruses. If you have Wine installed, then there is a larger potential risk, although I have never heard of anyone actually having a virus in Linux or under Wine.

Re: [Ltsp-discuss] Deploying LTSP as a replacement for XP
On Wed, Mar 19, 2014 at 05:40:47PM +, Norrie McKinley wrote: If anyone has moved small organisations over to LTSP from Windows could you please tell me how the move went? Was there much kicking and screaming from the users? I moved over our business (a couple of Honda dealerships with about 50 desktops) over to LTSP from Windows. I had no issues with users at all, being a smallish business, users could see that spending 300 pounds sterling per user for them to have MS Office over OpenOffice was absurd. I would imagine larger businesses would not have that benefit, and users would be likely to feel resentful, but certainly at our size of business, users felt close enough to the business to see the sense. It also meant that we could provide all users with an office suite, whereas previously it was only provided to those that needed it. This ability to provide all software to everyone is a great advantage. The reliability and uptime have been simply staggering. We've had whole years with zero downtime. When you come from the Windows world of regular reboots and painful Windows Updates and anti-virus, this is a revelation. But there have been problems: 1. Internet Explorer It transpired that many of our suppliers have extranets that are based around Active-X and are thus Windows only. And don't believe the posts that tell you that you can get Active-X working in Firefox - that is a Windows-only solution, where Firefox uses IE to serve up IE pages within Firefox. And amazingly in 2014 this remains a substantial problem, as corporate extranets tend to be changed far less frequently than websites, it is not uncommon for extranets to last more than a decade, over which time a website may be replaced several times. Our solution was to have a virtual machine running Windows to which users could connect via RDP. It works pretty well, but potentially leaves you with all the costs of Windows. And no, telling critical suppliers to support other browsers is not realistic. 2. Office Documents OpenOffice and LibreOffice are good, but not perfect. If you receive documents with embedded macros, then these will almost certainly not work, and the lack of the latest Microsoft fonts could result in formatting of documents being a little off. Some of the more advanced Powerpoint presentations can be an issue as well. In short - if you receive a lot of sophisticated office documents, then you may have issues. And, on the subject of macros, if you need macros in documents, then you will need a tame programmer to write them for you - they are an order of magnitude more difficult than in MS Office. Mail-merge has also been something of a headache, although certainly possible, it seems to be that little bit more difficult. Over the years I have found the best way of doing it and it works fine - but difficult to delegate to less than expert users. 3. Quick and easy database applications This was a huge loss for us, having written quite a number of dirty Access applications, these proved impossible to migrate. I ended up replacing some of them with Ruby on Rails applications, but the extra work required was not rewarded with any significant benefit. I know people despise Access, but for writing a quick and usable application for non-programmers, it is great. 4. Upgrades The one thing that I thought would be easy under Linux proved a nightmare. Free upgrades forever, yay! Then the excellent KDE 3.5 was replaced by the completely unusable KDE 4.0, 4.1, 4.2, 4.3, until finally, there was the usable KDE 4.4, by which time the distro had evolved too far for there to be a simple upgrade path. The loss of support for Kiosk-tool for KDE centralised administration, has been the other issue in KDE 4.. I would be quite keen to configure this for in fat client or mixed mode. We are all thin but I don't think users know that - as the performance feels local. Only full screen video really needs fat clients, at least in our experience. Where users require full screen video, then this is provided via local apps - which seem to me to represent the best of both worlds.

And then I would route through the config directory removing all files that don't need to be set for every user, and all lines that don't need to be set and of course purge them of all absolute paths. When the new user is created it will copy /etc/skel over and hopefully it will just work.

You could try experimenting with NX which I believe allows you to attach to existing sessions (subject to resolution availability), but I'm doubtful that this will give you a reliable solution - sometimes it takes a while for NX to realise that you have detached and screen resolution can be an issue. This is Linux though - it surely has to be possible somehow - you might just need to rewrite X and recompile the kernel a few times for good measure :). -- Chris Roberts http://chrisjrob.wordpress.com/ -- WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.

Re: [Ltsp-discuss] Syncing LTSP across two locations
On Mon, Mar 28, 2011 at 05:22:15PM -0400, Joseph Bishay wrote: We are in the process of building a new school, just down the street from our existing building, and I am looking for a way to allow seamless LTSP access between the two buildings. Ideally, someone would be able to log out at one location, walk/drive to the other building, and log back in and continue with full access to all their files. Unfortunately I cannot physically connect the networks of the two buildings -- there are other public / private properties between the two structures. I am wondering if the solution might be as simple as having two LTSP servers at both locations, and rsyncing /home between the two of them through the Internet? Does anyone have an experience with respect to such a situation? We have two Honda dealerships, and whilst our staff do not switch between sites very often, we do like to have synchronised shared data. Rsync is generally one-way, which isn't ideal for two-way file synchronisation, although I suppose if you work on the basis that each user can only be at one location at a time, it could work. Alternatively Unison uses rsync for two-way synchronisation. We started out using Unison using /srv/shared on each LTSP server. This proved to be a bad idea, as Unison uses a lot of resources during the synchronisation process. It did a good job though of keeping the files in sync though. If you opted to use Unison then I would recommend separating the data and unison process from the LTSP server, so that the load does not impact on your users. Keeping data off the LTSP server is probably good practice anyway. We then moved to using a central web-based Apache Webdav/SVN repository, which works okay, except that saving files requires decent upload bandwidth, not generally available with ADSL, and we are encountering locking issues with davfs2. All-in-all our experience is probably best used as an example of what not to do! That said, whilst your case sounds more difficult - sharing home folders - in practice it is probably easier, as you should never have both copies being edited at the same time. Perhaps an rsync prompted by the user's logout?

So you're recommending having a separate server for /home? Well, that is the logical conclusion from what I said; although I was discussing more my specific case, where it was shared data at /srv/shared. That said, I would have thought it was sensible in the ideal world to have no data on the LTSP server. It has the benefit that the synchronisation process will have little or no impact on the performance of the LTSP servers and leave you free to update and upgrade the server with the knowledge that the precious data is elsewhere. I have never tried this approach it has to be said. It would have some performance hit, but it should be pretty minimal with gigabit network, it would become more serious with video editing or rendering your next blockbuster movie, but for normal documents it should work fine. Perhaps someone has experience of this sort of set up? That said, it requires yet more hardware and yet more cost. And, if your users are only operating during the day, a night-time sync should have minimal impact. Just be aware that rsync and unison are both likely to have a hit on server performance, so either try and run the process out of hours, or separate from the server. I know you can set up rsync to work both ways -- you just need to specify how it acts when it comes across a newer file on the server, and make sure that the two servers have identical clocks. That said, whilst your case sounds more difficult - sharing home folders - in practice it is probably easier, as you should never have both copies being edited at the same time. Perhaps an rsync prompted by the user's logout? That may be a great idea -- have rsync/Unison triggered by the user logging out. I was also interested in fsniper http://chrisjrob.wordpress.com/tag/fsniper/ But it mostly comes down to bandwidth - if you have decent synchronous bandwidth between the sites, then you have options. I don't have any special bandwidth between the buildings -- it would have to go from one building - through our ISP to the Internet then down via the ISP at the second location to the server.

There is no reason that that method could not also be tackled via a one-off

Lastly, I tend not to use .wine as the directory. In fact I create a .wine

I'm sure there must be better ways of preventing users from adding their own

[Ltsp-discuss] Login with wrong password gives no response from server
I realised that I have been putting up with a small irritation in LTSP, assuming that it is a general issue, rather than being specific to me. When my users get their password wrong, they get a No response from server, restarting error. This then leads the user to bother me, thinking that the server is down. They do generally get used to this over time, but it does make them feel that the system lacks polish. This problem is compounded when the users are prompted to change their password, as it always seems to give this error, leading them to think that they haven't succeeded in changing their password. They then try fruitlessly to use their old password as they know that they haven't succeeded in changing it. I then get them to try their new password and of course that works. I have some users who have yet to successfully change their password on their own, which does add to my workload. I have tried googling, but, whilst there are loads of hits for ltsp \no response from server\ of course these are not related to this more general issue of the message itself being rather misleading.

[Ltsp-discuss] Local CD/DVD drive
On Debian Lenny (ltsp-backports) we are unable to mount local cdroms, although usb sticks work fine.

I have worked through the Ubuntu troubleshooter, with no issues, except that I was unable to locate the /var/run/ltspfs_fstab file mentioned.

Re: [Ltsp-discuss] is ltsp the right solution for me?
On Friday 11 Jun 2010, Brian Milliron wrote: I was recommended to ltsp by a user on one of the linux help forums. My situation is that I need a remote desktop protocol to communicate with a VM on my CentOS box. The default VNC protocol doesn't support sound and there are some weird driver issues with Red Hat Spice on Debian flavored distros (using Ubuntu as the VM). So I'm looking for something else, and this was recommended. Only I'm not at all sure that a protocol intended for thin clients to communicate with a server is going to work in this situation where there is no thin client and no server. I've looked over the docs and it looks like ltsp is expecting a PXE boot process which is not going to be the case in my situation. It also seems there could be an issue with loading appropriate drivers on the VM OS. So before I get too much deeper into this I wanted to ask if I am wasting my time even trying this? If all you're trying to do have remote desktop access to a VM, then you want NX not LTSP. I use FreeNX on the server and NoMachine.com's client.

So there will always be some terminal trying to receive an IP from it. Anyone here with a solution to this? With all the issues with wireless security, I decided that the best solution was to keep the wireless network completely separate, with its own DHCP server. I use IPCop for our firewall and this provides a green interface for our LAN and a blue interface for our wireless LAN and provides DHCP for our wireless network, leaving the LTSP server providing DHCP for the LAN. You can choose to allow access from the wireless network to your lan, or permit individual clients, or just block everything and insist that your wireless clients use openvpn to connect. The latter is the method I have chosen, and it works well. With the addition of Advanced Proxy and URL Filter, the IPCop server also provides web filtering, with identd running on the LTSP server it even logs users' Internet use, without them having to authenticate on the proxy server.

Re: [Ltsp-discuss] rdesktop lock ups
On Wednesday 29 Apr 2009, Job Cacka wrote: So after reading through your thread I would ask if you found any documentation on how the routing should be setup. Specifically a best practice for LTSP environments. I have seen other problems with LTSP performance because we do not use an internal DNS, and ended up creating a large host file that we propagate to the Thin Client with a script and run on the server. However, in my four years experience of running thin clients I have never seen a network admin's guide to providing the proper foundation of services. I think there are unique situations with the combination of services that LTSP requires for educating admins before they get themselves into trouble. Providing you have a single gateway on your network, and providing it is set up as the default gateway in dhcpd.conf, and providing that gateway has the hosts properly defined (or dns set up), then it should just work. The issue for us, is that we have an additional gateway/router set-up inside our network, which needs to have the windows rdp traffic. The default gateway is set-up with a static route back to this gateway, so again it should just work. And it does for 15/20 minutes sometimes, and then it goes and drops a packet or two, just sufficient to break rdp. This just should not happen in a decent network, and I have got to get to the bottom of why this is happening. For the time being I have set up and RCFILE script to add the static route to the clients, and the problem has gone away. But I really do see this as a sticking plaster over serious issue. Ideally I would replace our ipcop firewall, with a multi-wan firewall, and move this router outside of our network. -- Chris Roberts +--+--+ | Distribution | Debian Etch | | LTSP Version | 5.1.10-1~40 | | Windows Manager | KDE 3.5.5| | Kernel | 2.6.26-bpo.1-686 | +--+--+ | Distribution | Debian Lenny | | LTSP Version | 5.1.10-2 | | Windows Manager | KDE 3.5.10 | | Kernel | 2.6.26-2-686 | +--+--+ -- Register Now Save for Velocity, the Web Performance Operations Conference from O'Reilly Media.

Re: [Ltsp-discuss] ltsp works like citrix?
On Wednesday 29 Apr 2009, Mohammed Riswan wrote: please answer my quesion if anybody knows, is ltsp is works like a citrix metaframe? can we create an individual sessions same like citrix for all the users? We use metaframe and ltsp, so I should be able to answer. Once the users have logged in, it works just the same as metaframe, with each user have their own user account and session. They log in/log out etc all pretty similar to metaframe. There is no in-built method of shadowing users, but various open source applications may be installed to fulfill this need. Users can be logged off easily enough. The key difference is that with metaframe you need to have a client operating system. Okay, you might buy dedicated thin clients, but they still have to have an operating system - even if it's only Windows CE. You then connect from that client o/s to the metaframe server. With LTSP, the LTSP server provides the client operating system at boot time. Thus the client can literally be bare metal (I always disconnect the hard drives). Thus with LTSP you only have to maintain the server, and the single client operating system which resides in a chroot directory on the server. The other key difference with metaframe, is that by default, LTSP won't work across subnets, and in particular across low-bandwidth connections. But we get around this by installing FreeNX on the server, and connecting from remote fat clients using NoMachine NX Client.

Who knows - perhaps it could even be installed onto a Linksys router - there isn't much that hasn't been done with those things. * Create your own live cd/usbstick to boot That said, wonderful though freenx is, I'm not sure I would choose to connect that way for day-in-day-out working.

Can I have the pxelinux.0 ,ltsp kernel and file system Image on an XP machine? I struggle to understand, perhaps this makes more sense to others? Running these services from Windows, is like trying to fit a square peg in a round hole; do enough hammering and you might succeed, but why make your life so difficult? Stick to Linux for tftp, dhcp and nfs, it'll be easier in the long run. If you are simply wanting to connect from a Windows XP Client to Linux, then there are several options, which are listed on the following page: http://wiki.ltsp.org/twiki/bin/view/Ltsp/Clients#Microsoft_Windows_to_LTSP_server Personally my preferred solution is to install freenx on the server and use NX Client to connect. I read that LTSP-5 uses the kernel of the host linux machine. It uses /a/ kernel installed on the server in a chroot at /opt/ltsp/i386, not the kernel of the server. ITC, I will I be able to use LTSP-5 for the said situation? Or should I switch to LTSP-4.2, where the kernel is separate? Stick to LTSP5. Is it true that Ltsp client files are stored in /opt/ltsp/i386 ? Yes. Also, how is it possible to have .img file containing all files in /opt/ltsp/i386 ? If I make an image of the File system and put it along with kernel and pxelinux.0 in the Windows tftp server, will the ltsp client machine extract the .img to a full RFS? What are the instructions to be given? Is it there in linuxrc file? I suspect that what you're suggesting is technically possible, but I doubt it has ever been done, and why go to such a huge effort to end up with a solution that will be less reliable than a normal LTSP installation. If you really really need to run LTSP from a Windows box (which I struggle to understand) you'd probably be better off installing a Linux LTSP Server into a virtual machine.

The plan is to boot Linux over network and use RDP client in Linux to connect to Windows Terminal service. I am not exactly sure why this ex-Microsoft guy wants only WIndows XP as server, not Linux server. Worth finding out - you could have this working using a traditional LTSP set-up in an hour or so, including having clients booting rdesktop automatically. But the problem is that he isn't able to get this working on latest Intel Atom boards and Amd Sempron machines, due to the fact that the kernel doesn't have neccessy drivers for NICs on these boards. So, what he wants from me is a kernel that can be loaded by PXE boot and a file system that gives an rdesktop. Is it feasible at this point? I would say so, but it makes my head hurt - it's probably the most convuluted method of connecting to a Windows machine imaginable, and does nothing to avoid the licensing costs. -- Chris Roberts LTSP Version: 5.1.10-1~40 Windows Manager : KDE 3.5.5 Distribution: Debian Etch Kernel : 2.6.22-3-k7 -- SF.Net email is Sponsored by MIX09, March 18-20, 2009 in Las Vegas, Nevada.

I don't believe that there is any such licensing structure for Windows XP, so your best bet is probably to buy retail licences for every user (ouch!) and even then I'm not sure that it would strictly adhere to the eula. For Windows Server 2003 I was told that I did need the terminal services CALs. UK prices six months ago were 22 GBP for the server CALs and 64 GBP for the terminal services CALs. I will be sick as a parrot if I've been wrongly advised. As I understand it, it is critical to opt for user-based licensing rather than device based licensing, and (at least when I last looked into it) it's best to downgrade to Windows Server 2003 rather than the current version which uses RDP v6.

Re: [Ltsp-discuss] Speedup Adobe Reader 8
On Monday 15 Dec 2008, M Rathburn wrote: We're having a slight problem with Adobe Reader 8.whatever being somewhat slow on our thin clients. The screen updates are what's slow - the file is already downloaded completely and displayed. We're running on a big-phat-juicy server, so the problem isn't going to be in lack of processing power there. So I'm wondering what some workarounds or other options there are. Under Edit Preferences | Internet you could try switching off the Fast Web View, and also make sure that you enter a proxy server in the Internet settings. These were workarounds to stop 100% CPU usage, which may or may not be fixed now. Anyway its a two-second thing to try, so worth doing. We find all the pdf readers to be slow when scrolling if they're maximised for page width. I've always just accepted that that is a factor of LTSP. 1. If we ran Adobe Reader as a local app, would that help or hinder? Does anyone have experience with that? and if so, what are the configuration steps necessary to make that happen? I've never used local apps, so I am probably revealing my ignorance here; I've always assumed that it was necessary for PDF reader to be on the same machine as the file manager, email client and browser - i.e. the three applications that actually use the pdf reader. 2. What are some other alternative PDF reader programs available that have similar capabilities as Adobe Reader, but would be faster to render? Ex: We need to be able to view thumbnails, and also to be able to read annotations. I like kpdf, but at the end of the day, acroreads printing abilities are absolutely superb - in particular the ability for end users (i.e. non geeks) to be able to create booklets is just fantastic. Also, kpdf does not enable field input - which you simply need to be able to do on occasion.

[Ltsp-discuss] x11vnc: connection refused (111)
I tried installing x11vnc using the instructions on the following page, but but when trying to connect I just get connection refused (111). * https://wiki.edubuntu.org/InstallX11VncOnLtspClients I have killed the process on the client and run manually, but it completes without ever stating PORT=5900 as you would expect, even if I specify the port number on the command-line. Sure enough, if I run netstat -ant before and after x11vnc, no additional ports appear. I have installed nmap on the client and run nmap localhost but this states that the host is down. nmap -sT -P0 -p 5900 localhost returns: PORT STATE SERVICE 5900/tcp filtered vnc If from the server I run nmap -sT -P0 -p 5900 clientip then it returns: PORT STATE SERVICE 5900/tcp closed vnc And just as a final test nmap clientip: PORT STATE SERVICE 6007/tcp open X11:7 So no great surprise that it's not working, but I am at a loss to know why x11vnc cannot activate the port. I don't believe there is any firewall running on either client or server, and both are on the same subnet (LTSP server was installed with a single NIC); so I don't believe any other firewall should be influencing things. I've spent the best part of two days going around in circles with this, so any pointers gratefully received.

Re: [Ltsp-discuss] Thin Client Hardware
On Wednesday 18 Jun 2008, Sean Carte wrote: Does anybody have recommendations regarding thin client hardware for the clients? I see HP offer a few, including the NeoWare range. Has anybody used these with LTSP? We have a couple of HP t5700 series machines, which PXE boot straight into LTSP without fuss. These are the XPe type machines, presumably buying the Linux embedded versions makes more sense (at least MS isn't benefitting!). We have used Wyse 9235LEs which work fine, but are very slow. But I'm not sure that you need thin client hardware - these tend to have flash memory and an O/S, neither of which you need with LTSP. So consider buying a low-power barebones PC (perhaps a Via or Epia, preferably fanless). The key thing is that they must PXE boot, which almost all modern hardware does. For example I've bought a number of MSI Axis 700 Lite PCs, these are small form factor and have everything you need except RAM (and possibly an optical drive), both of which can be fitted in seconds. They work in both 4.2 and 5 without a problem, and can be bought for around £100 sterling ($200) - considerably cheaper than comparable thin client hardware. And if, in the future, you move away from LTSP, you can add a hard drive and install the O/S of your choice...! I've also built a couple of PCs and I was particularly pleased with the tiny Cubid 3688 case with an Epia m/b and dvd-rom, which cost about £170 ($340) but is absolutely gorgeous and took less than an hour to put together (you could probably halve that if you were doing a number of them). -- Chris Roberts LTSP Version: 5.1.3-1 Distribution: Debian Etch Windows Manager : KDE 3.5 - Check out the new SourceForge.net Marketplace.

[Ltsp-discuss] Changing /opt partition
Finally decided to upgrade to LTSP5, but before I do, I need to sort out an old problem which I have been putting off. For reasons far too complicated to go into (AKA I screwed up) I have ended up without a separate /opt partition. In itself not a huge problem, but unfortunately this has resulted in the / partition being closer to capacity than I would like. Fortunately I have a massive and unused /archive partition (on /dev/cciss/c0d0p12 filesystem) which I am not using. I therefore want to unmount /dev/cciss/c0d0p12, change the mount position to /opt and remount. Given that /opt is only used when clients first boot, and /archive is currently unused, this would seem quite straightforward and safe. My plan is simply to do: # mv /opt /home/opt # umount /dev/cciss/c0d0p12 Edit /dev/cciss/c0d0p12 mount point in fstab to /opt # mount /dev/cciss/c0d0p12 # mv /home/opt to /opt Test!

[Ltsp-discuss] Via VT8237 Audio
We have a number of desks in a showroom environment and wished to have a energy efficient, compact thin client, with a flange for fixing underneath desks. To that end, I bought from linitx.com a Packbox Mini-ITX case with a Jetway J7F2 1.2Ghz Eden CN700 mainboard and a passive PSU. End result a 7-watt ultra compact thin client... Booted into LTSP 4.2 first time, although as normal with the CN700, the video falls back to vesa (as the quality is perfect, I just stipulate that in lts.conf to avoid the error message). Unfortunately, whilst the sound started, it immediately chopped off. Same behaviour every time I booted. Thought this could be an IRQ conflict, but reconfiguring in the BIOS made no difference. Tried unmuting PCM, Master Mono, although given that the sound was starting I felt this was an unlikely fix. Googling suggested switching off the IEC958 Playback device, but no better. Tried setting SMODULE_01 to snd_via82xx dxs_support=0, then 1, then 2, then 3, then 4 and 5 - no joy. Finally, more in desperation than from any real expectation, I set the device to pick up an older Kernel (2.6.17.8) and miraculously the sound sprung into life (the usual kernel is 2.6.20.9). My LTS.conf for this client is simply: XSERVER= vesa SOUND = Y SOUND_DAEMON = esd VOLUME = 90 MIC_VOLUME = 0 CD_VOLUME = 90 So the good news is that these J7F2 boards do seem to make good LTSP thin clients, the bad news is that they may not work with Kernels above 2.6.17.8! Given that we will be upgrading to LTSP5 in the next 12 months or so, this is a concern, and before I order another 5 of these, it would be great to try and fix this problem. Is there anything I could compare in the two kernels to try and determine what has changed in respect of this device?

Re: [Ltsp-discuss] memory, swap, diskless

Yes, because you are logged into the LTSP server, it is natural that that is the memory you are interrogating. In few words, there's written if I have a client with 32 mb ram I should use swap files. Do you have less than 32mb RAM, I think you'd be talking about 20-year-old kit! I really don't think that this is a worry, unless you really do have exceptionally old equipment.

Re: [Ltsp-discuss] LTSP 4.2 Local Devices
On Monday 24 Mar 2008, William Cody wrote:
Issue I am having is that when I unplug a
device or remove a CD, it doesn't always unmount the device, so next time I
go to use the device it sometimes doesn't function properly, or it will
show the device as being mounted, but the device will show no contents on
the drive or disk, even though I know there is data on it.
The two important files that govern local devices are:
/opt/ltsp/i386/etc/udev/rules.d/15-ltsp-block.rules
and
/opt/ltsp/i386/etc/udev/scripts/ltsp-device.sh
Fortunately they are both relatively straightforward to understand.
As you will see, the device name is all important in the way that the
detection and removal is handled, so I found it really useful to modify
ltsp-device.sh so that the line that writes into syslog would give more
information:
logger udev ${DEVNAME} detected ${ACTION} of ${LTSP_DEVTYPE}
Then insert and remove the USB key and watch syslog for changes. For example
I just inserted a USB key...
Mar 26 08:57:53 ws162 root: udev /dev/scsi/host0/bus0/target0/lun0/disc
detected add of disk
Mar 26 08:57:53 ws162 root: udev /dev/scsi/host0/bus0/target0/lun0/part1
detected add of disk
... and then removed it...
Mar 26 09:00:14 ws162 root: udev /dev/scsi/host0/bus0/target0/lun0/part1
detected remove of disk
Mar 26 09:00:14 ws162 root: udev /dev/scsi/host0/bus0/target0/lun0/disc
detected remove of disk
Obviously you can also watch from the client shell, but that isn't always as
convenient, particularly after the event!
Good luck.
Kind regards

[Ltsp-discuss] Load average when copying large files
I notice that the server load average escalates dramatically when copying large files on the server. cp is not most Google-friendly command, but, from the research I have managed to do, this is clearly normal behaviour; it's only the nature of LTSP (being a shared system) that makes this a problem. So my question is, is there a way to restrict the IO when running a command (cp in particular), thereby sacrificing speed in the interests of keeping the server usable for others? Thanks!

Re: [Ltsp-discuss] cannot switch consoles

Is this just on one terminal, or all? Are you confident that LTS.conf is loading fully without parsing errors? Might be worth posting the section of LTS.conf that pertains to the terminal in question. Regards, Chris Roberts - This SF.net email is sponsored by: Microsoft Defy all challenges.
