I know that Pawel @ http://garage.freebsd.pl has a patch for making private SysV IPC memory spaces for the host system and each jail: http://garage.freebsd.pl/privipc.README The patch is against 4.x though, and I've never tried it. I would really like to see something like this implemented for 5.x though. Does anyone know if there are plans to implement this in the future 5.x releases? If not, I would be interested in helping anyone that wishes to try implementing this in 5.3 soon, as we have a lot of clients who ask for SysV IPC inside of jailed hosting environments. Or perhaps there is a new IPC implementation that FreeBSD is looking at and perhaps they will dump SysV IPC altogether? -- Justin Hopper <[EMAIL PROTECTED]> UNIX Systems Engineer BSDHosting.net Hosting Division of Digital Oasys Inc. http://www.bsdhosting.net _______________________________________________ [EMAIL PROTECTED] mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-hackers To unsubscribe, send any mail to "[EMAIL PROTECTED]"
