My guess... Xvnc is the VNC server process. It has to be running for you to be able to connect on http://host:5801 (unless you use some inetd magic to get it to auto-start). Basically, you have Xvnc running ready to accept connections on http://host:5801. Why is it using so much CPU? I'd guess that you've got a screensaver configured. The screensaver program isn't intelligent enough to realise that it's a VNC session and therefore doesn't need a screensaver, so it detects that there has been no keyboard or mouse activity for a while (unsurprising, since there are no connected clients), and starts running the screensaver. The Xvnc process has to respond to the screensaver program's commands to draw things on its X desktop, and this is what is taking all the CPU. It could be other things, but this is my best guess. -- David SmithWork Email: [EMAIL PROTECTED] STMicroelectronics Home Email: [EMAIL PROTECTED] Bristol, England GPG Key: 0xF13192F2 -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

I assumed that Linux DVD players were still bound by the region encoding on the drive, but ICBW; I don't bother playing DVDs on my PC as I've got a "proper" DVD player downstairs. Of course, the next question for the OP is - Can you play PAL (region 2) DVDs on your PC? Is it just the "NTSC" ones that you can't play, or is it all commercial DVDs? -- David SmithWork Email: [EMAIL PROTECTED] STMicroelectronics Home Email: [EMAIL PROTECTED] Bristol, England GPG Key: 0xF13192F2 -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

AFAIK, there should be no reason why a PC shouldn't be able to play NTSC DVDs. PC DVD drives are, however, region locked. You can usually change the region a fixed number of times (e.g. 8), before you then can't change them at all. It is possible to download replacement firmware for some PC DVD drives which overrides this. However, if anything goes wrong, you may make your DVD drive completely unusable. i.e. do it at your own risk! If you already have a domestic DVD player, have you tried to see if it can be region-unlocked? Some players can be unlocked by entering a "secret" code on the handset. Do a bit of internet searching before going out and spending more money. As other people have mentioned, region coding is a scheme mandated by the large US media corporations to allow them to control the markets, and is, quite frankly, a royal PITA.

Can SuSE 10.2 do that? OK, stupid question first - have you actually tried to play them on a DVD player in Spain? Most TVs nowadays take both NTSC and PAL. Your main problem is likely to be region coding rather than NTSC vs PAL. Get yourself a multiregion DVD player in Spain, and you'll probably be fine.

I haven't seen much use of SuSE, but lots of RHEL replacing Solaris because the performance:price ratio is much better.

Surely then, it would be a better policy to restrict downloads to those who are actually playing the game? E.g. use some kind of "port knocking" style scheme where only IPs that are connected to the game server can get to the webserver? Restricting it to UK-only does seem overly punishing. For example, if I wanted to play your game at work (I wouldn't, as it's against company policy, but let's say I did), then my accesses would appear to be coming from France (since that's where the company's internet gateway is), so I would be blocked, even though I'm most definitely on the northern side of the English Channel... -- David SmithWork Email: [EMAIL PROTECTED] STMicroelectronics Home Email: [EMAIL PROTECTED] Bristol, England GPG Key: 0xF13192F2 -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

"tar" files are a bit like ".zip" files under Windows - they are a collection of files brought together into one "ARchive" [1] - except that there is no file compression performed (so they take up approximately the same amount of disk space as the sum of all of the original files). The .bz2 extension means that the tar file has been compressed with the 'bzip2' utility. You might also find .tar.gz files (where the file has been compressed with 'gzip') and .tgz (which is a shortened form of .tar.gz) To extract all the files, you use one of the following: tar xvf .tar tar xzvf .tar.gz tar xzvf .tgz tar xjvf .tar.bz2 [2] However tarfiles are not like .rpm files that SuSE uses for packages. RPMs are specifically designed for a Linux distribution, and often contain commands to run after the files have been extracted to install the tool into the correct place. tarfiles are /just/ collections of files (like .zip files in Windows). Often you will find that a tool distributed as a tarfile is just the C source, which you then have to compile. This means that they are easy for the tool provider to distribute (since they don't have to provide different RPMs for different distributions), but it's more work for the user (i.e. you). I'm afraid you have to use a bit of intelligence and detective work to determine how to get the tool to work after you've extracted the contents of the tarfile. Often you will find that the tarfile contains a file called "INSTALL" or "README"; these might give you some clues. HTH... [1] In case you're wondering, the "T" comes from "Tape". In the olden days of UNIX, the 'tar' command was mostly used for reading and writing backup tapes. To some extent, it still is, but most computer users nowadays will never have seen a tape drive, let alone used one... :-) [2] 'man tar' will give you much more information on how to use tar; possibly more than you're able to digest. -- David Smith| Tel: +44 (0)1454 462380Home: +44 (0)1454 616963 STMicroelectronics | Fax: +44 (0)1454 462305 Mobile: +44 (0)7932 642724 1000 Aztec West| TINA: 065 2380 GPG Key: 0xF13192F2 Almondsbury| Work Email: [EMAIL PROTECTED] BRISTOL, BS32 4SQ | Home Email: [EMAIL PROTECTED] -- To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
