It should be noted that for Linux, there's no _option_ of spending hours, reading man pages--the included documentation in Linux is (a)nonstandard, (b)unstandardized (something different entirely!), and (c)incomplete. (Sadly, Sun is going this way as well--Solaris 10 man pages are decidedly substandard.) Be that as it may, I think your original post was generally misunderstood --it sounded to me (and others apparently) that you were essentially asking, "I have a new computer. What services should I turn off?" Without any idea of what your server is for, the answer is "I dunno." I don't know of any lists out there, but something that will help with most services is "svcs -l <servicename>". In fact, you could extract the FMRI and NAME fields from that output, and create a list in a matter of a dozen lines of perl, most likely. Also, _do_ read the man pages for smf(5), svcs(1), and svcadm(1). The first one will explain most of the services that aren't immediately evident from the service name. (things like the restarter, f'rinstance) Colin

Worse, some of those Linux man pages are outright wrong. E.g., su(1), which states: "The current environment is passed to the new shell." However, duhring(a)maxwell:~$ su Password: root(a)maxwell:/home/duhring# pwd /home/duhring root(a)maxwell:/home/duhring# cd root(a)maxwell:~# pwd /root root(a)maxwell:~#

That > shouldn't be a tall order. > man restarter man identity man coreadm If there's a list somewhere, I don't know where it is. You don't need to read each man page in its entirety! The top two inches or so should give you sufficient clues for most of them. |
