The Capabality to do certain things (like configure ethernet devices, make device nods), many of which are disabled within a vserver because they relate to hardware or kernel access and therefore would be unsafe to pass onto the root user in a vserver. > Can you limit the memory usage or cpu usage ? Nope. Not at the moment. You can set the `nice' value for the vserver compared to other vservers by setting: S_NICE="" and setting: S_FLAGS="... sched" Open files and core-size can be limited with the `ULIMIT' line. The User beancounter patch may be a possibility for some other stuff too: ftp://ftp.sw.com.sg/pub/Linux/people/saw/kernel/user_beancounter/ > I can't find the include/linux/capability.h file in the > kernel-2.4.19ctx-14.tar.gz tarball. find /usr/src/linux/ -name capability.h -Paul -- Nottingham, GB
