    I'd stick to PC's. Mac's hardware is good, but overpriced for what they are. They are pretty stylish, and OS X is a great operating system, but they charge a lot for what you get.

     

    If your after something stylish, quite a lot of the home orientated manufacturers like Asus, Acer, Packard Bell etc have some good reasonable priced machines that look pretty good, but as with everything, you pay a price for the extra style.

     

    Plus, if you start using it for your business, you'll probably end up with things like accounting packages, and windows only software that you need to be running, so its probably a safer bet. Even though you can run windows on a Mac, you still need to pay for a windows licence.

    As much as I'd love to sit in my car at night and play pop shots with Johnny Tea-leaf, I need to get a decent car alarm. I've plumped for a Toad AI606.

     

    Its costly, so I'd rather get it installed properly. Anyone know of a Toad dealer anywhere around the Sheffield area. Don't fancy paying someone from Bristol to come and do it. :|

    I've heard the security on it is as tight as a drum, also MS said that with the revised security measures any Service Packs in the future wont be necessary, with all the patches etc coming through Windows update.......................... but like you say its too early to be sure.

     

    Thats what they said about XP. I've got a couple of virtual PC's connected the a virtual DC, and a lot of the Group Policy settings from 2k3 AD don't apply properly to Vista. We have Vista Ultimate and Enterprise licenses, due to our software assurance agreement with Microsoft.

     

    But with 700 PC's in our domain, and another 900+ to go, we need to be rock solid sure before we deploy it.

     

    Office 2007 is schedules for March deployment, followed by Exchange 2007.

    Its not surprising really. Computers are sold to novices who with all respect to them, don't have the first clue about computer security. Its not their fault really, its amazing the number of PC's that are sold with little or no protection on board.

     

    For the sake of 5 mins to install AVG or the likes on a new computer in the store, it could prevent a lot of these.

     

    Although, it does make you wonder how the figures are reached, and how much of it is scare tactics. Not that there is anythings wrong with that, scare tactics are good in this case.

    Thanks for that _ had a look at the text files and it all looked very suspect indeed. So we can assume that there's an IRC server running - and the server is being used as an ssh attackbot.

     

    There's no evidence of .bash_history or any of the other log files as having been altered (i.e they contain a complete record, including my logins) - and it doesn't appear that the root account has been compromised, but as you say, nothing is intrinsically trustworthy anymore.

     

    Just because the files don't look to be altered, its quite possible that they hacker could have just cleared out any of his activity.

     

    I don't suppose you have an IP of the last login to that account do you?

     

    I've locked out the ssh login to only allow connections from my personal IP - I did that about 3 days ago, and then deleted the compromised user. I'm arranging for a clean server to transfer the sites to, and then edit the DNS A name entries and then the MX entries (after laboriously setting up new mail accounts...).

     

    /var/log/secure shows that brute force attacks and compromised account logins have stopped completely. I've changed the root password to , oh wait, i'd better keep it a secret.

     

    How am I doing? (Thanks again everyone).

     

    Sounds much like your server was probably turned into a node for a botnet. I've seen IRC channels on ERFnet filled with bots. Its quite remarkable the number of bots that people accumulate.

     

    One channel consisted of at LEAST 200 zombied machines connecting into a single channel, and the perpetrator issuing commands to them, and then them going off and performing DDOS and god know what other sorts of attacks.

     

    It sounds like you were the victim of a script kiddie rather than a full fledged hacker. So chances are, he's got no further than he did.

     

    Script kiddies generally use other peoples programs to launch attacks, hackers usually write their own. A very similar tool set was used on another box I've seen.

     

    Although that time, the password was brute forced, and there wasn't that much of the box left that was recoverable after the intruder found an exploit in BIND which someone was running as root (tut) which gave them root access, and suffice to say the run of the box.

    Don't know that much about security side of linux but isn't xine a video/media player?

     

    xinetd is a replacement for inetd, which is a "super server" that a lot of UNIX servers used to, and still do use. It basically listens on all available ports, and passes incoming connection to the relevant program, I.E passes HTTP requests to Apache.

     

    Many people don't use this method any more and set-up the server programs to directly listen on the ports. This method reduces high overheads on busy servers. Its usually distribution specific as to what method its set-up to use, although most can do both.

    wow... i didn't think people had *that* much kit in their homes... and i always thought of myself as a geek! So naive...

     

    .

     

    I used to have a lot more: http://www.linuxmod.co.uk/misc/images/picKLE-cache/Room/dscn1066_640.jpg

     

    Had that little lot running as a cluster for a while, but sold most of them off after I finished what I was doing. Computers are generally expensive as a hobby, from all angles. I know people who have a lot more kit in their houses. I moved a lot of my stuff into Telehouse and Redbus on more powerful kit, so I needed less at home. Plus I don't take on as much extra work as I used to, I just don't have the time with my new job.

    Not that's some serious setup... serverS (plural) and a UPS... your home seems like it might be geek heaven... :D

     

     

    .

     

    One big file server, dual opteron processor with 8 disks, real power hungry. Two Sun Ultra 80's and an an Alpha 433au.

     

    The firewall is pretty low power, A Soekris embedded routerboard, if that makes up for anything :D. My house mate has two servers also. I cant really turn mine off overnight as they run some critical jobs, plus one does all the fileserving for home directories for my desktop machines.

     

    I'm eventually looking to get rid of the Sun's, once I've ported the apps to FreeBSD from solaris. Also one of my desktop PC's is going this month, now I have my d420 laptop , I no longer need it so its being retired, the only justification I had for it was it was the only machine I run for Windows, but thats on my work laptop.

     

    I'm trying to get the setup down to 2 servers, one desktop and a laptop. My housemate is doing the same.

    Cabled mics are far superior to radios unless you are going to spend a lot of money.

     

    The most expensive I worked with was a rack mount eight reciever box from Sennheiser.

     

    £50,000..........

     

    I'd vote for the Sennheiser gear too. The radio mics they make are incredibly good, both in sound quality, and in build quality.

     

    I used to engineer for a large swing band, and we use complete Sennheiser wireless pickups, the quality is really good, not to mention built to last, which, in the world of clumsy musicians, is a bonus. Shame they don't make them anymore. We used SM58's for vocals

     

    I'd spend money on a decent mic, the SM58 is one of the best, if not THE best cable mic around, that and a good set of quality cables.

     

    I'd go somewhere like ElectroMusic in Doncaster and ask if they will let you have a demo, they usually will. If your nice enough to them they might even let you loan one for a weekend so you can test them out. They are really good like that.

    Its not the first incident of this kind. A UK station ran a similar competition, which required competitors to sit on blocks of dry ice. Many of the contestants were submitted to hospital with severe burns, some even had to have skin grafts.

     

    How long is it before people realise the stupidity of running competitions first without doing proper risk assessment. I have to do a risk assessment form for what I consider menial things in my job.

     

    It also begs the question how desperate are some people for the latest fads, why not just wait a few months and pick one up via the normal way. Or even better, tell the kids to stop whining and go out and play football like I did as a kid. Ok I may be being a fuddy duddy here, but if I shouted and screamed for something as a kid, I got a clip round the ear.

     

    Ok, she may have been doing it as a surprise, or some other motive, but still, its partially her own fault, and partially the stations fault for not ensuring contestants were properly cared for during and after the event. Doing anything out of the ordinary to your body poses health risks.

    I'd be very wary of Toms Hardware, whilst once upon a time it was unbiased information, over the past couple of years there has been an increase in the bias natures of some of their articles.

     

    My advice, never use just one site when looking for reviews, same as when your buying hardware. Shop / look around and make sure you see a couple of reviews of what your buying, and make sure they tally.

     

    A couple of others that are useful for checking out:

     

    http://www.anandtech.com

    http://www.bit-tech.net

    http://www.hexus.net

     

    That latter two are both useful if your interested in the performance aspect of PC's

     

    My advice, get the Core 2 Duo, its worth the extra money.

    Captain Knee Jerk.

     

    The fire was caused by an electrical fault. Fireworks bring pleasure to many people, and apart from genuine accidents, most people are killed or injured by their own stupidity.

     

    Like hairdryers with "do not use in the shower" tags, if your stupid enough to stick a rocket up your arse you deserve injury.

     

    My respect to the firefighters, at the end of the day, it was a tragic accident, and they are only the 11th firefighters to be killed since 1990 or there abouts, which shows the tremendous skill and training these guys have.

     

    It was a tragic accident, if it had been another oil depot, or a gas storage facility, it would have been the same, unless there was criminal negligence, which will be proved true/false in due course.
