Heya,

I am currently running a box and i would like to have my sshd,ftpd or either my inetd running just on purpose remotely, when im not at the office.

I have heard about portknocking (on /.) - do you have any idea about how good it can work, its failures (denial of services possible, hacker sniffing the tcp sequence in order to replicate it, only TCP used?) .. well mainly how wide it is used and if there is any good distribution of a such software (thats kind of professional) ?

Thats gonna give me a right idea about how interesting this solution is for me.
