maybe a good questions, but *shame on me* that I found this: http://linux-vserver.org/Documentation after sending my mail to the vserver ML :) This is much what I can read/learn and there is also a *paper* to watch: >>> http://rehash.whatthehack.org/wth/rawtapes/wth_linux_vserver/wth_linux_vserver_140.mp4 *g* As I saw it this afternoon and saw the name Pötzel, Pötzel... I know this guy, that was the nice guy on this mailinglist who cared about my problem with > 5 mintues wrong going hosttime.... ;) Not go on with discussion, short update: That thread stated on 19. Mai 2006 um 13:08h: Subject My ISP unable to use ntp ;( BTW, faktime is runnig fine, the offset is now 539s ;( I modificated libfaktime and compiled it myself wrote /usr/local/lib/libfaketime.so.3 into /etc/ld.so.preload and run every hour a skript who messure the offset and write it into /etc/faketime/.faketimerc Once I knockt out myself by cp to the file libfaketime which was in used - I had to ask my ISP to delete /etc/ld.so.preload But the time of filemaipulations (written...) are not influenced by this preload.... So it is a 100% perfect solution..., but it works, even with asterisk Next time I will write a short howto about this. So back to your video - thank you for your effort for vserver linux - I saw it and I was wondering before if vserver is just a jail or more .... ;) > thing is, fd and pts (/14,/20 ...) are 'just' names > used for character and block device nodes, identified > by the unique major and minor identifiers ... > > so, basically c:136:14 means the 14th pseudo terminal > (regardless of the name, could as well be named hansi) OK, I should have run a vserver on my laptop to know more when I rent a vserver at ISP.

I fear I will miss loopback/encrypted/ssh filesystems... And at this very low prices for this vserver 3 Euro/month I can't expect that the provider likes to be asked to add something. But this very low price is a dream - you can't run your own PC 24/24h for this - the power would be more expensive - own mailserver, asterisk, ssh, ssh2 via javaclient also in my bibliothek where is only a webclient, mutt ..... ;) This came possible with all the people who work on vserver :) man bash, opening mailfiles, searching... that all is on my vserver via ssh is several time faster than on my PIII 600Mhz Laptop ;) BTW I don't know if there is a tool, that combines ttyrec with an audiorecording (e.g. ogg) with that would be possible to make very small tutorials - don't get me wrong, I don't ask you to do more I'm just thinking about what would help that more people get the knowledge to use vserver ;) But there is already a lot to read/learn :) > take a look at the following urls for more details: > > http://linux-vserver.org/Linux-VServer-Paper > http://linux-vserver.org/Caps+and+Flags > http://linux-vserver.org/Resource+Limits Thank you for your patience. > > Ok, but can you confirm that I'm able as [EMAIL PROTECTED] to remove e.g. > > /dev/tty without the chance/right to restore them with an backup? > > yes, but your provider could 'protect' you from > harm here, by making them immutable, but then you > still could remove all your binaries and libraries > without a chance of restoring them (except for a > backup :) Ah, yes, I know the power of rm -rf *. (But for me it was harmless) ;) No I was asking for devices on vservers - when I rm /dev/tty I can't help me with a backup myself - right? Sounds this protection is optional - not every provider is so kind. Is there any good reason to allow a guest to remove devices? When not, the tools for provider should have "kindness" as default and not opt-in ;) But I still don't got the point why it should be a security risc, when [EMAIL PROTECTED] can create a textterminal himself - give me some time to read the documentations, to learn and understand :) Grüße aus Aachen, rob _______________________________________________ Vserver mailing list Vserver@list.linux-vserver.org http://list.linux-vserver.org/mailman/listinfo/vserver
