Re: [Dorset] Remote Desktop to a Raspberry Pi
So whats wrong with ssh on its own, or if need a gui x11 tunnelled over ssh to an x-server on the remote?

However, before I could start anything serious, I wanted to sort out remote access, so that I could program on the Pi while still having full access to my normal machine - without resorting to a KVM Switch. I thought about using VNC, but my experience on Windows lead me towards Remote Desktop because it is more responsive. I installed it, it worked, I shut down the Pi, it no longer works.

We are looking for a solution that can be hosted within our Corporate network, preferably on Linux servers. I've had some brief exposure to Atlassians Confluence software, which you can buy to self-host or pay for monthly per user as a service and it seems pretty good, though like all things it has a bit of a learning curve. I've only barely used it though, so can't say much about it other than people I work with have given it very high praise. It's probably better if you buy into the rest of Atlassian's suite of tools like Jira and Hipchat, etc but by itself I don't imagine it's too bad. I don't think having to pay is the issue; it's about having it hosted on our network. Speaking of Hipchat, that might actually fit the bill. It's basically an IRC style private chatroom client, but depending on the plans you get (and you can even use it for free with unlimited users if I recall) when you attach images or files to messages, they stay in the system so they can be referred back to, at least for a time. If what they need is something more real-time rather than a long-term document storage/sharing system, then that might work out well for them. I use hipchat extensively at work for communicating with my team, sharing files, talking to clients, holding meetings, etc and find I rarely use anything else for sharing things, getting feedback or collaborating on projects. I can highly recommend it, and since you can trial it for free, if it sounds like it might fit the bill, I'd encourage you to investigate it. We also use their dev API to feed in info from our various monitoring tools for servers, software builds, support tickets, etc so it acts a company-wide notification system as well as shared communications platform.

Vendor updates have been released for all Redhat Enterprise Linux, CentOS and CloudLinux distributions. ** All UKDedicated managed servers will be automatically updated ** If your servers are unmanaged, then is absolutely essential that you ensure your servers are fully updated. Use the yum package manager to update and protect against exploitation of this vulnerability. To ensure all packages on your systems are fully updated, run the following command from a root SSH session: yum -y update This will update all packages on your system without further prompts. You must maintain your SSH session for the duration of the update. If you only wish to update the bash packages: yum -y update bash Again, this will update without further prompts. You must maintain your SSH session for the duration of the update.

I would agree that the main reason for running a virus scanner on a 'pure' Linux machine is to avoid inadvertently passing on Windows viruses to Windows users that I communicate with. As I say, please prove me wrong :) AFAIK, there are viruses that attack Android (ref Natalie's earlier post). It may be that the virus databases also include Windows viruses for the same reason as above, but I'm not aware of this. You must acknowledge that even a pure Linux machine is not invulnerable, although social engineering seems to be the only successful attack vector. Android is slightly more vulnerable than a pure Linux machine since the users generally have full root privileges, plus it is a more attractive target, so I would be very surprised to hear that there are no Android viruses. I also use Avast (on my windows boxes) and am indeed happy with it - but AV s/w for Linux and android - show me some proof that they actually do something (and don't tell me they are root-checkers please!).

It needs therefore to be reasonably easy to get working for a lay person and also to get data back when needed. Any ideas? Cygwin + rdiff-backup? Can be run on demand from a shortcut or on a schedule. IIRC, the syntax to create a backup is pretty much 'rdiff-backup $source $destination'. In case you haven't used rdiff-backup before, you'll end up with a copy of the files which can be recovered easily using regular file-system tools (the sync method you said you didn't want ;) ) but as well as that you can recover to any point at which you created a backup, as it stores diffs or similar. Of course as it never deletes anything automatically the disk might run out of space if there are lots of changes, but it is possible to remove older backups somehow.

Re: [Dorset] Backing up Disc Images
Or just use clonezilla to create the image Martin On Saturday, 11 February 2012, Terry Coles d-...@hadrian-way.co.uk wrote: Hi, The intro to this is off-topic, but the question isn't. It's a bit long winded, but it does illustrate why we prefer Linux. Feel free to jump down to the problem below if you don't want to read about the saga :-) My wife's MSI Laptop popped its clogs a week or two back and after a bit of investigative work, I realised that the hard disc had failed. In fact this diagnosis was much harder than it needed to be because I couldn't find a hardisk diagnosis tool that would run properly on Win7 and the disc manufacturer's test disc claimed that it couldn't find a compatible disc. In the end I booted the machine from the PartedMagic disc and used their disc testing tool and Bob's your Uncle. Novatech were their usual helpful selves and told us to return it to them for repair because it was inside the MSI 2 year warranty (not theirs) and a few days alter we had a nice new disc with Win7 SP2 installed. So far so good. Now for the problem. That miserable company, Microsoft, no longer allow OEMs to include a Windows Installation disc with their computers and they don't allow them to create one either (they are currently suing Comet over this). What they do allow is that the OEMs can put a recovery partition on the disc and provide a program for the user to create a recovery DVD from it. When the laptop was new, we used this program to create a Win 7 Recovery DVD, (which we still have). Win7 is now at SP2 of course and Novatech re-imaged the machine with their SP2 image. Being a conscientious type, I thought I would redo the recovery DVD, but Windows burner exited with a Windows system error (0x80004005), which basically translates to 'I haven't got a clue'). After wasting lots of dual- layer DVDs, I came to the conclusion that there is nothing wrong with the DVD writer, the problem is somewhere in Windows. Being an obstinate type, I wasn't going to be defeated by crappy Windows software, so I looked around for another way. I thought I had the answer! Using PartedMagic, I would create an image of the recovery partition, burn that to a dual-layer DVD from within PartedMagic and then, if the hardisk failed again, we could restore it. Only one problem; the partition is 12.5 Gigs (and is nearly full) and the DVD can only take 8.5 GB. Even that seemed surmountable; both Clonezilla and PartImage can do compressed images, so I gave them a try. I started with PartImage, but it warned me that NTFS support is experimental, so I went over to Clonezilla. Neither tool can burn to the DVD directly, so I created a 15 GB partition at the end of the hardisk and formatted it to ext2. Clonezilla went all the way through and then exited with a bunch of error messages I couldn't make head or tail of. There was nothing usable in the target partition. I then tried PartImage again and ignored the Warning about NTFS support. This went almost all the way through, but stopped with the message that the disc was full and where should it put the second volume. So (at long last) here is the question. Why does PartImage need a bigger partition to store its image into than the one it came from, even though I am using compression? Secondary question; is it creating temporary files in the target directory? If so, how much bigger does the target partition need to be? I've Read The Fine Manual.
