Hi all

1. I have noticed that when I boot, I have loads of services starting that I dont want/need, and no doubt they are slowing my boot.

How can I remove them?

2. How does the syntax for chmod work? I know 777 is allowing all access (i think?) but what does 777 actually signify?

3. Can I get banned for asking too many questions?

Thanks

Hong

Also, what kind of maintenance should I be doing on this system? IE is there a Linux version of defrag, cleaning temp files, etc?

The easiest way to disable services from starting when you boot is to make the individual service located in either /etc/rc.d or /etc/init.d (depending on your distro) not executable. Some distros have GUI's which can visually allow you to see what is turned on (such as SuSE). Others you will have to use the command line to change the permissions (such as Slackware). As going into how file permissions work under Linux would require a bit of explanation, here is a link to get you started...

If you are going to change file permissions in the CLI, use the "chmod" command.

1) There are a couple of ways to do this, but best to use a gui services app... I don't know what knoppix has tho. In any case you have enough power to cover it and most are needed.

2) It's a bitwise opperator... You break it down into binary ie 7 = 4+2+1 0r 111 (all three bits set) (for the read/write/executable) while the 5 in 755 would be 5 = 4+0+1 0r 101 and so forth

3) No.

4) Linux filesystems have inherant systems to minimize fragmentation, so there are no defrag tools. It also does a lot of it's own housekeeping by default...
