If nothing else it's an education in how to (not?) to design a UI for a tablet device. The Word Processor/Spreadsheet app (Kingston Office) which came with the tablet (Lenovo Yoga) actually copes quite well with the stuff I've thrown at it so far. However I was also hoping to map out tools which would be usable via a remote session for BYOD at work - i.e. allowing users similar access to what they have from their work desktop, but without any data being downloaded (or downloadable) to the device itself. And while I could just run virtual Windows machines with VNC, Linux/Unix seems a much nicer fit. Running a browser based application is looking like a better solution, but although there seem to be at least 2 projects underway porting OpenOffice to the web, there doesn't seem to be a sable release yet.

[Scottish] Window manager for tablet?
Hi, I'm looking for suggestions for WM which will be usable on a tablet (i.e. small screen) VNCing onto a Linux box. Really I want to run all my apps full screen without the expense of a menu bar. Although most tiling WMs allow this, it's rather difficult to do alt+tab with no keyboard! Hence I'd want something with a conventional task bar and a launcher would be nice too (not least so I can write an app to switch the 'mouse' buttons). Thus far the only taskbars/launchers I've seen for tiling WMs are very minimal (and very small to poke with my fat digits). I usually use KDE: my ideal solution would be to get rid of the window decorations / force stuff to run full screen. Anyone got any suggestions?

Hi all, Currently the software evaluation list looks like pligg / anahita / openoutreach. ...but I'm also looking for any recommendation on cheap UK-based hosting. While I can find lots of very cheap hosting companies claiming to operate in the UK - nearly all of them have their datacentres in the US/Canada. It's not that I've got anything against the former colonies - but I already have a site hosted in Florida, and although packets go back and forth at around half the speed of light (I measured it - how sad) the latency is a killer. Uk2.net do have at least one datacentre here - but for the basic package they don't tell you where it's hosted / don't give you any choice in the matter. Easyspace seem happy to wave the flag. I've used 123-reg for DNS before, but not for web hosting - but they don't explicitly say their datacentres are in the UK. Anybody used any of them?

[Scottish] BBS / mini social network network software
Hi, As the computer guy, I've become responsible for the Scottish Rat Club's website (my daughter breeds and shows fancy rats). The current online provision is not great - some static HTML pages and a freebie invision BBS. Increasingly online activity is moving onto facebook :( I think we could do a lot better with the SRC website - and hence looking for suggestions as to software to run it. I'd want a basic CMS, a BBS, support for blogs, user pages - public and member only splits. User admin is essential, other nice things would be: - mobile client (HTML5 app / responsive design / native app) - configurable archiving - payment processing (but this is down the list a bit) Since I spend my working day untangling Java mess and this will be running on a cheap virtual host, it'll need to be LAMP. And since, when I'm not untangling Java, I'm fixing performance problems and fighting phishing, I'm not particularly keen on Wordpress nor Joomla. Googling for open source CMS turns up *lots* of different packages - but wading through their websites to find out how well they meet my needs is rather tedious.

Format your harddisk, reinstall from source media then deploy your bespoke code / data from backups. Meanwhile try to identify how the system was compromised and plug the holes. However if you're using a shared host (i.e. don't have root access) that's far from trivial. In an ideal world you'd get an image of the system to analyse offline to investigate what happenned - one of the reasons for needing root access. Are you using off-the-shelf third party code on your site (e.g. a CMS). If so, which one? Have you checked for known vulnerabilities? Are we talking about the website matching your email address? what harm could my websites do if something nasty has been left behind? It could just be sending out some spam - or you might be hosting a phishing site which costs e victims thousands of pounds every time someone visits it. Or it could be getting used as a proxy for controlling a bot army. So anything between very little and quite a lot - you might consider pointing your DNS elsewhere till you've got some confidence in identifying what's happenned here (you did ensure that you bought your DNS registraton seperate from your hosting?). Your ISPs assertion that the shell was compromised suggests that the attackers probably did not gain access via vulnerabilities in your website (which is how most attacks start). Can your ISP show that the access was via ssh? If not can they say with confidence that it was not via ssh? Were other accounts on the system compromised? An important question you'll have to visit very soon is how much is your website worth to you? And how much are you willing to spend to get it back on line? Do you want to continue using the same hosting company? Thre's going to be a lot of work involved in getting your site back - this reply barely scratches the surface. There are lots of very capable IT people here on the list - depending on what you use you website for / whether you think it worth paying someone to get the service restored, they may be able to provide more specific support.

Digital Rights Management or DRM commonly refers to software that is designed to control or limit how a file can be played, copied, downloaded, shared, or accessed. DRM-free means that the MP3 files you purchase from Amazon.com do not contain any software that will restrict your use of the file. They don't seem to publish any details of the file format - and the only way to buy albums is by using their binary only program. Since they have at least gone to the trouble of porting the program to Linux (and producing a Fedora9 package - I'm currently running Fedora 9) I was **even** prepared to use it, but trying to install it turned up lots of missing dependencies - it seems I'd at least need to install a large part of Gnome to get it working.

[Scottish] Bluetooth woes
Hi All, I recently bought myself a whole PC (having owned the previous one for about 10 years, replacing the mobo and the memory a few times, the hard disks a couple of times) and had all sorts of grief getting openSuse to get on with the hardware. Eventually we came to a compromise - openSuSE would talk to my USB devices if I let it fsck /dev/sda5 every time it booted, and take forever to start up the software respositories when accessing software updates through yast. This was using openSuse 10.2 with an unoffical kernel. But after a while I got fed up. Looking on Distrowatch, I saw that PCLinuxOS had not released for a while - I've previously enthused here about the 2007 distro which is still running happily on my laptop. Unfortunately a quick boot suggested I was going to have more USB problems with this distro. Despite the peer pressure, Iive never really liked Ubuntu nor the other Debian based systems (though my mother's PC is still going strong with an oldish Debian install). I eventually decided to revisit RedHat - Fedora 9 is fairly recently released and has a very recent kernel. Indeed all the hardware seems to working very well, and yum is actually relatively painless to use. I can't say I'm as impressed with what's happenned to KDE - but this is a very early release of KDE4 so maybe things will change. To get back to the point - yes I've got Fedora 9, but I'm not too adverse to changing it, but need a newsish kernel. Meanwhile $ork have decided to enroll me in the Order the Blackberry and unto me bestow a 8800 device. And while walking around Tesco's at the weekend, a Bluetooth dongle fell into my shopping basket. What happy coincidence. At least it would be if I could get the damn things to talk to each other. The phone recognises the computer, pairs with it and subsequently lists it as a paired device - and vice versa for the PC - but it seems like nothing else on my PC can find the phone. Konqueror reports 'Protocol not supported Bluetooth', Dolhpin doesn't like Bluetooth either, kbtobexclient can't find any devices, kbluemon sees no devices, kbluelock sees no devices. The errors with the filemanager are obviusly due to a missing I/O slave - but I'd like to at least have a *reason* to fix them before trying to do so. Anybody out there got any ideas?

Shouldn't the filesystem (GFS) take care of this? The data doesn't have to be fenced, it just has to be available. Any cluster system needs to be able to determine where control resides if only a portion of the nodes are available - this is fencing. Have a read off the stuff at the Linux-HA project, and google for Stonith. Definitely read the GFS docs - http://www.redhat.com/docs/manuals/csgfs/admin-guide/s1-ov-perform.html Because you are in the unusual situation of having a machine with guaranteed availability within the cluster network (although not behaving as an equivalent cluster node) you could easily script the 'manual' fencing solution for GFS - but RTFM first. Note that cluster filesystems are designed for low-level concurrency and may acheive this by trading off performance. A quick google suggests there are comparisons of NFS, ext3 and GFS available. And when you say OLTP, I presume you mean Online Transaction Processing? I'm just figuring out your terms and reading up first, so I might not be on your wavelength here... It's just straight data files. No databases or anything... Yes, OK - so RAID 5 makes sense for a small network then (assuming that latency is not an issue). I also understand what you are saying in your last paragraph. I'm not very articulate, as you can see! I was meaning that you can't access a SCSI drive/device independent of the machine that's hosting it. Yes you can - you just need to set the id of the other adaptor to something other than 0 - people have been doing shared disks this way for years. iSCSI will happily work with mutliple host accessing the same disk. In both cases, though, you still need a cluster-capable filesystem if the disks are trully shared (as opposed to merely occupying the same bus with a failover option - but we're back to fencing again here). I have thought about this and I see what you mean about pushing the RAID over the network (I think). I was wondering if it would actually work! After reading about DRDB though, this is exactly what I'm trying to achieve. Would there be any significant gain in using something like DRBD over a software RAID1 on the host? Apart from the fact, it is DESIGNED to do what I want, of course. :) I'd always seen DRBD as something more of a realtime backup solution - and I can't envisage how you would use it from multiple hosts without a clusterFS again.

One thing which hasn't been mentioned yet in the thread and which you really want to decide on BEFORE you go shopping for parts and working out how to connect them is what this box will be doing - typically RAID1 is a far better soltuion for OLTP than RAID5. It might also be advisable to offer tiers of availability and performance (and you could something really lever with overlays to make them appear as a single filesystem). But pushing the RAID control across the network is a recipe for disaster and certainly would not give a performance benefit compared with a server based filesystem exported across the network. I don't want to use SCSI because it's direct connect and can't be used on more than one machine at a time. erk - alarm bells ringing.

[Scottish] Holy 3D batman!
Hi all, About a year ago, Lawrence showed me Beryl (the Window manager with cool eye-candy accelerated graphics stuff). It was very, very impressive. I recently had cause to reinstall my [c|t]rusty old laptop (1GHz / 384Mb / 10 Gb). I was toying with the idea of a solid-state system using PuppyLinux, but thought I'd experiment with PCLinuxOS first. I downloaded the latest PCLinuxOS which boots up as a Live CD distro with an option for HD install. It comes with Beryl as an option. I started up Beryl not expecting anything much but was amazed at what it could do with the very basic graphics card (i830). Certainly not all the effects are supported - but a surprising number of them are - in fact my only grumble was that they mostly went so fast that, if you blinked, you missed them. So if you want to impress people (or just want something a bit more funky on your desktop) you don't have to have the very latest in 3D hardware to get some very impressive results.

Yup - just packets - and the port numbers are different too - sure you're
router's not just leaking extra echoes of other traffic through? (I've got
cable using a modem rather than ADSL, but can see other local peoples traffic
on my interface).
It seems improbable that a hacker could compromise your machine and come up
with a combinaion of private subnets which would actually allow then to route
a connection back to another host.
If you're confident that your kernel, lsof and netstat are secure then its
looking increasingly unlikely that your machine is involved - how likely is
it that a hacker would build their own TCP stack?
I've done some basic things to check for a rootkit:
Downloaded debs to get md5sum and netstat binaries and
checked them against the installed versions.
Downloaded chkrootkit and compiled it.
As far as I can tell it didn't report anything dodgy apart
from some dot files in /usr/lib etc, which seem to be
benign.

I tired looking in /proc/net/{udp,tcp} as discussed here:
http://lists4.opensuse.org/opensuse/1999-06/msg01069.html
if my convoluted hex conversion scripts are to be believed
there was no mention of any 172* ip addresses there.
If you can't trust /proc what can you trust?
This also seems to favour the leaky net theory over the rootkit theory.
If you can't demonstrate to your own satisfaction that these are not coming
from your machine, try demonstrating they are coming from elsewhere by
changing the address/subnet you are using betwen your PC and router.

The problem is that i want to address both of these servers via the net

eg:
o Firewall accepts the connect and passes it on to web1
o web1 checks the servername and then forwards the connection onwards if
it is for web2.
So far this is fairly straightforward.

web2 has complex urls ie http://web2/index.php?3d%2FC4sbo2w%
web1 also has complex urls with /index.php
VirtualHost *

ProxyRequests On
ProxyPass /media/ http://web2/
/VirtualHost
I don't understand what you are asking for that wouldn't be satisifed by the
above.
I suspect that its possible just with apache configs, but I'm hesitant to
provide an example when I don't really understand what your asking. Can you
give examples of URLs and the files they reference on each webserver along
with the network architecture (e.g. is there NAT on FW?).
Since you asked for alternative approaches:
Try using a smarter switch in front of the webservers e.g.
--[FW][SQUID][Web1]
\
\
[Web2]
Of course Squid need not be on a seperate box.
Alternately write a wee wrapper on Web1 to redirect requests to Web2 (about 10
lines of PHP if you're pedantic) listening on a different port (or
implementing port mirroring with iptables) but sharing the same external
address then hang it either on a specific URL or the 404 handler:
?php
$otherURL=http://public.address.com:82/some/path/;
. $_SERVER['QUERY_STRING'];
if (strstr($_SERVER['SERVER_PROTCOL'],'1.0')) {

We have now found that we are finding that some of the components are not working as the discs which were supplied are for windows only. OK, first thing is that the Microsoft/Intel thing has created quite a different way of supplying/building a system. In the Linux world (mostly) all the software (usually) comes through the same channel. Sometimes it's a good thing - ever tried to coordinate 4+ suppliers to resolve a technical issue? Ever done it when you're responsible for less then than 0.001% of their turnover? Enough of the advocacy stuff. So can you give us a bit more background - was this bought as a complete system? Was the OS included in the same purchase? Did the vendor pre-assemble the system? Burn it in? Install any software? The reason I ask is that if you were a sold a new, pre-installed SUSE box which doesn't work, then it's up to the vendor to sort it out (Sale of Goods Act 1979 (as amended)). Assuming you bought the bits yourself and/or you really want to work through this yourself then First SuSE 9.2 is reasonably good at detecting hardware (often seems to come on duff media though). If this is a boxed version of SuSE then bear in mind that there are people getting PAID to help sort your problems out. Read the stuff which came in the box for how to register your product and obtain technical support. What I am in need of is a person who can sort this out and get the system working properly. There's lots of very skilled (and some less so) people on the list. Are you looking to pay someone to come in and setup your system or some hand-holding and nudges (usually freely available on the list) ? Regardless, it'd probably help to build a bit more background...have the components worked with other OS? When you say the graphics card isn't working properly do you mean the system will only start up in text mode? or you never see anything on the screen? To get you started... Video card - your uses a an ATI radeon processor. ATI do supply Linux drivers from their website, in rpm format but it doesn't say which distro these are targeted at. SuSE also provide rpms at ftp://ftp.suse.com/pub/suse/i386/supplementary/X/ATI/suse92/i386/fglrx/8.10.19/ I guess you have access to a working machine connected to the internet.

How can I get the local PC's to 'see' each other by hostname rather than only by IP address ? Simple way would be to populate the hosts files on all machines (if you can't find a file called 'hosts' on the MSWindows boxes, it should go in the same directory as the file 'hosts.sam'). Of course if you want the names to be static, you'll need to tell your DHCP server which MAC address belongs to which machine (or turn off DHCP and use static addresses instead). You could do DHCP+DNS, or even dynamic DNS, but IMHO DNS is a bit of a pig to manage (even on a private network) and the problem is exacerbated by having to deal with BIND. For less than 20 PCs, I'd definitely go with static addresses and hosts files. I have also noticed that the router only displays the Windows PC's hostname in the client list. It does not show the Linux PC's hostname. Is there anything I need to run that will allow the router to determine the hostname of the Linux PC's ? Maybe it's getting the list from NMB broadcasts?

It lets you define how long and how much news to keep. Its brilliant in a low-bandwidth situation as it only downloads groups which you have tried to read (recently). The only thing I found it didn't do was local newsgroups - but there's a fork which now does exactly that. Can anyone give me a pointer as to what I need to install on it to do the job. Hopefully there'll be RPMs available, as I don't think the Toshiba doctored version of Red Hat has much in the way of development software installed. For leafnode, edit the config file and go! You might have to kick your newsreader a couple of times before it realises that its talking to a different news server with different message IDs, but once that's sorted then that's about all you need to do. If it's still an intel PC then you should just have to compile remotely and upload (scp).

Include the ongoing cost of upgrading the software and hardware to accomodate it (OS upgrade every 3 years, application upgrade every 4 years). Try to put a figure on the hidden costs of admin time; I reckon that in the last 6 months (Blaster, Welchia, MyDoom) have directly or indirectly cost me about half a day for each Microsoft PC in my work. I would expect to pay at least £25/hour for someone to do this adequately for me. Although these machines are driven by technically literate people, I will still spend a significant amount of time fixing broken configs/installs just because the machines have lost the plot or the users have done something stupid. Putting machines into a public facing scenario also requires a great deal of specialised hardening. (The most effective way I've seen of doing this was to use Ghost to create disk images which are restored at regular intervals - obviously, the images need to be maintained properly). Committees are talking shops, but don't be misled - if you play them at their own game, you stand a good chance of losing, don't be argumentative - talk the proponents and ask them how they would advise you to solve the problems of locking down the machines, remote management, egress filtering, but cost out the tangibles and as much as you can of the intangibles then ask the board if: 1) they want to spend this much money replacing a proven system 2) if they can quantify exactly what they would gain by spending the money 3) justify why the money should be spent on dismantling something which delivers. (it DOES deliver, doesn't it?) Another good way to make them stop and think (but make sure you've wayed up your opposition first) is good old-fashioned spoiling - ask the cheif Microsoft proponent to produce a Microsoft machine so that the board can see for themselves in a straight comparison.

I will add PCI IDE controllers to accomodate the extra drives. The 4Gb drive will have probably linux (possibly jumping ship to freebsd), and i want to set the other two up in some form of LVM/software RAID setup. Jings, how much porn does one person need on their home server? But seriously LVM was originally designed to allow very big filesystems to be built using small drives. There was no load balancing / redundancy. HP then built their software RAID solutions on top of LVM. You don't need LVM to do RAID on Linux. Indeed, having looked after HPUX boxes for some years I'd stay away from it altogether: 1) it makes life more complicated than it has to be 2) If you do build disk spanning partitions using LVM then suddenly your backed into running a system which is not easily migrated to smaller partitions. 3) It makes your system more complicated than it has to be 4) backups / restores / replacing components is a lot simpler the more granular a system is - LVM doesn't just hide the granularity, it actually takes it away. The only good things about LVM are it gives you the ability to take 'snapshot' backups (this is unlikely to be a priority for you, and anyway you can do this with software mirroring on Linux) and sometimes you do need very large filesystems (if you can find a DBMS which has large file support but no disk / datafile spanning capability). Read the excellent software RAID Howto. I'd also suggest you have a look at www.linux-ha.org since your main interest is in maintianing your data. You've said you want some redundancy - keeping the main drives mirrored but on seperate controllers will give you redundancy on the controllers as well as better throughput. If you already have a CDROM on this machine, I'd suggest you invest in an extra IDE controller and move the 4Gb and CDROM onto it (or the 60Gb drives if it is a higher spec than you MoBo adapter). Take some time to think about how (if?) it will boot if hda goes down - do you need a boot floppy? If you need to edit the fstab how will you get access to it? How do you boot the root filesystem off a RAID device? Starting with 2 disks mirroring is the obvious way to go, but where to next? If expect to extend the array, then your choice of level will have a lot of impact on what bits you need to add and how you go about integrating them. Note that you can mirror mirroed devices - so if you can comfortably backup 120Gb, and know you'll be getting more disks soon, you might take a lyer and setup the current pair as a stripe set then, when money allows add another pair and mirror your existing stripe set on them. If, say you can divide the disks up into 10Gb chunks then you've got a lot more freedom to mix and match configurations without having to backup then restore *ALL* your data each time you make a change (e.g. mirroring for root filesystems, mirror+stripe on home directories, RAID 5 for data directories, swap and /var not on RAID and three way mirroring for GPG keys and x509 certificates). Have you got a backup solution / plan in place? If not, I'd make this more of a priority than building your array if your objective is data integrity - mirroring will write bad data to all disks! Even if you don't have the hardware in place to do backups - its worthwhile reading your entire filesystem regularly to highlight any bad blocks which may accumulate. (tar --exclude=/etc/nobackup -cvf /dev/null / - or something like that). Hope thats not all too obvious...
