Possibly overkill but you could ssh in, install x11vnc (which is a vnc server that provides vnc access to a running X session), run it and then vnc into your machine - tunnelling through ssh for security of course :) Cheers, Steve

Malicious Javascript
by Dan 07 Sep '10

07 Sep '10

Dear All, Browsing with Namoroka 3.6.8 on Gentoo, I just stumbled across a webpage containing Javascript that was probably trying to install malicious code on my system. The script - claimed (implausibly) to be a malware scanner, and (even more implausibly, because the places it claimed to have looked were Windows-specific directory names that don't exist on my system) that it had found half a dozen items of malware on my system; - generally made a nuisance of itself by grabbing focus with dialogue boxes (this seemed odd - my browser settings forbid Javascript to raise or lower windows, yet my main browser window was, to all intents and purposes, irreversibly lowered by the presence of the dialogue boxes, and the only browser actions possible were to click on dialogue box buttons or do a window-manager close on the dialogue box) - did a passable impersonation of Windows Update (or at least, it would have been passable if the system I was looking at it with had been running Windows ;-)); and - finished up by offering me a download of an executable Windows binary, which I rejected. I took a look at the Javascript source code, but it was _very_ obfuscated. My question is - could the script have got any sort of access to my local filesystems or otherwise done any damage? -- Thanks, Dan

Copy files and change case - any ready made utliities around?
by Chris G 06 Sep '10

06 Sep '10

I want to keep two directories in sync but with a slight difference, I want the 'destination' directory to have lower case names only. I.e. any file in the source directory that has an upper case name (or any upper case characters in its name) I want copied to the destination directory with a lower case name. I guess I can come up with solutions that need me to write a wrapper script of some sort for rsync but I was wondering if anyone has any ideas for a ready made solution. This needs to be run as a cron job by the way. -- Chris Green

NAS Drive mounting help
by steve-ALUG＠hst.me.uk 06 Sep '10

06 Sep '10

Hi Gurus! I've been given a Netgear SC101 which I'm intending to use for backups. I found a post somewhere about how to mount it, and I have mounted it, or at least I thought I had until I rebooted and it was no-longer mounted. The steps I have to take are: sudo modprobe nbd sudo ut listall sudo ut attach {DRIVE_ID_FROM_LISTALL} /dev/nbd0 sudo mount -t ext4 /mnt/sc101 /dev/nbd0 Line 1 adds a device driver to the kernel line 2 finds the drive's "id". You only need to run this once - the ID doesn't change line 3 "attaches" the drive to the system. line 4 mounts the block device at my chosen mount point. I've added a line to FSTab to take care of line 4, but the problem is, I seem to need to do line 1 and line 3 after a reboot before I can mount it. Q1: How can I make a modprobe "stick" to survive a reboot? Q2: Where should I execute line 3? Q3: Should I should manually mount there too, rather than using FSTab? I'm attempting to use BackupPC to backup my files. This runs as a service, and requires that drive to be running to start. Q4: Is there a way to conditionally start a service, dependant on whether the drive is present or not, or should I just let it attempt to auto-start and live with it failing if the drive's not there? Any help much appreciated! BTW, the reason I'm attempting to use BackupPC is because it "folds" identical files from multiple PCs into 1, i.e. it doesn't store multiple copies - i.e. it de-duplicates the backup, hopefully allowing me to backup multiple machines without buying loads of disks! Cheers Steve

Something keeps creating a file called %1 on my system, has anyone else had this happening and, if so, do they know what's doing it? -- Chris Green

BMJ and Firefox
by Ted.Harding＠manchester.ac.uk 03 Sep '10

03 Sep '10

Hi Folks, I've just had an interesting experience with the BMJ website: http://www.bmj.com With Firefox (Iceweasel) 2.0.0.19 all I see is the banner logo at the top of the page. The rest is pure blank, though this blank page is long. With an old IE, all is fine. I next tried Firefox (Iceweasel) 3.0.6 on another machine again all is fine. I've never had trouble with the BMJ before. On their front page they do state that "bmj.com has moved to a new technical platform" and that there are some problems; but that seems a bit unlikely as explanation for complete failure to display content on one browser version, yet display properly on another. Any comments? With thanks, Ted. -------------------------------------------------------------------- E-Mail: (Ted Harding) <Ted.Harding(a)manchester.ac.uk> Fax-to-email: +44 (0)870 094 0861 Date: 03-Sep-10 Time: 14:13:02 ------------------------------ XFMail ------------------------------

program focus
by nev young 02 Sep '10

02 Sep '10

Hi all, One of the major annoyances I had with MS Windoze was the habit of programs to force themselves into the foreground. I would have some long running task running in the background, or will have started a "slow to fire up" program, meanwhile I continue working on "the task in hand" with the program in the foreground. When I looked at the screen I see the background task has popped up and forced itself into the foreground and the last half dozen sentences I had typed had been lost to it. I have noticed that this is also becoming more common with linux (unbutu 10.04) and was wondering if this behaviour is a part of the programs themselves or if there is a system wide setting that will stop it. That is, I want to be able to specify that the foreground task I am using does not lose focus unless I tell it to. Anybody out there have more in depth knowledge of this sort of thing? Nev

Wanted - workaround for broken date entry on a web site - any ideas?
by Chris G 02 Sep '10

02 Sep '10

I'm trying to register my Mobistar internet dongle. Their web programmers are obviously a bunch of total idiots, especially on the usability front. Not to mention that they make the site ridiculously secure for no good reason, the only way you could lose information or money there is if you, by mistake, charged someone else's SIM. However that's all by the by, it would be really good if I could actually get our dongle registered to allow us to view our usage and to recharge it. When we tried a few weeks ago it was impossible because the Mobistar website wanted to send an SMS message to our browser and couldn't because we're not running IE on Windows. So we gave up. I just retried and now it allows me to say "I can't receive SMS" at which point it allows entry of the PUK instead. Whoopee I thought, now I can register. No such luck, I get past the first few entries of phone number and PUK but then in the personal information bit it wants to know my date of birth and the pull down boxes for the day, month and year don't work. No problem I thought, I'll do it in IE in Windows, just the same (well slightly different symptoms), can't enter date of birth. I've also tried Konqueror, still no good. Can anyone suggest any workarounds that might allow me to get a date into the right place? The symptom in Firefox is that the drop-down box is the size for just one number and is blank, the symptom in IE (and Konqueror if I remember right) is that the drop-down is quite tall but is still completely blank. I have tried entering numbers even though they don't appear and tabbing through the entries but it still refuses to think I've entered a valid date. -- Chris Green

Windows domain interoperability
by Mark Rogers 31 Aug '10

31 Aug '10

My work desktop (Ubuntu 10.04) is in an office managed by an SBS 2008 install (as much as I hate it, I kinda like it being something that I can wash my hands of when there's a problem!) I'm looking at the extent to which I can "benefit" from the domain, as much as a learning exercise as anything else. At present I have a couple of CIFS shares mounted, and I get my IP via DHCP and my email from the server via POP3. I discovered www.likewise.com at the weekend. Does anyone have any experience of (the free open source version of) LikeWise? Are there better/different options? To be honest I'm not really sure what I would like to achieve that I don't already have, but like I said this is a learning exercise more than anything. -- Mark Rogers // More Solutions Ltd (Peterborough Office) // 0844 251 1450 Registered in England (0456 0902) @ 13 Clarke Rd, Milton Keynes, MK1 1LG

cheap laptop broken screen
by Richard 30 Aug '10

30 Aug '10

Please somebody put this to good use, a replacement LCD panel is about 50 quid. I think around 50 quid is enough to ask for it (or nearest offer). I wont be posting it though, I can bring it to meeting or you can come and get it. http://i.imgur.com/wDNej.jpg It's an Acer Aspire One A150 netbook. Atom 1.6GHz (N270), 1GB RAM, 150GB HDD. Charger and battery work perfectly. Cheers Richard -- Richard Bensley - 07540878285
