jail.c patch

Hello, I've been reading this thread. I made the augustments to the patch so that it first checks if it is an IP address, if it is not, it then tries to see if it is a hostname. If neither are true it exits with an error. Hope this is what you're looking for, Evan --- jail.c Mon Jul 30 06:

IMPORTANT!! Re: panic on mount

Hello, Just to clarify things for everyone who may be having this probme: there is a panic on bootup with current, within the witness* code. You can avoid this by commenting out WITNESS in your kernel configuration and recompiling. It worked for me.. Hope this helps someone. Thanks, Evan John

interesting -current project

Hello, Since the relaes for 5.0 was extended another year, an interesting feature I'd like to see go in to the kernel is hooks. So users can add extra security checks.. etc. There's a project in its beginnings right now, www.freesoftware.fsf.org/jailuser/ Think anyone could join the prfw mailing

hooks

Hello, I need each system call to check with a master table of restrictions before executing a function. Is there a way to do this without copying and pasting a bit of code that does this checking into every system call? Thanks, -- --- Evan Sarmiento
