HI all, I'm hardening one test box and at present I'm planning to do: # chflags -R schg <file> where <file> will be some binaries that seems to be common targets for rootkits and lammers: ls du ps find top locate strings ifconfig netstat login I wonder if changing these files permissions as I've shown above will be cause some troubles in future upgrade (recompilation, the classic way, not the binary upgrade one) process. żIt will? -- I must not fear. Fear is the mind-killer. Fear is the little-death that brings total obliteration. I will face my fear. I will permit it to pass over me and through me. And when it has gone past I will turn the inner eye to see its path. Where the fear has gone there will be nothing. Only I will remain. Bene Gesserit Litany Against Fear.
