httpd is Apache web server. Since you have one machine on a dial-up,
you obviously don't need to run a web server.
identd is something you also don't need because you are on a dialup ws.
If you were running a server it might make sense.
if you type: man identd or man httpd you can get some info on them.
(man is the "manual" command).
There are most likely a few other processes that are also started for you
that you dont' need. This is because the "workstation" installation
that you must have chosen installed several packages that you do not
need. I think RedHat assumes a "workstation" is connected to a LAN
and so they install a lot of goodies that many people will want. However,
since you are not on a LAN, things such as a web server don't make sense.
There are also a couple of processes that are essential for laptops, but
abosolutely unnecessary for desktop computers: pcmcia and apmd
(pcmcia is "card services" for pcmcia cards; apmd is for battery power
management on a laptop).
So, how do you get rid ofthem?
You can always kill a process (e.g. kill -9 5474 will kill one of the
identd processes you show listed below (the process id number is in the
PID column of the ps listing which you show below). However, the processes
would just start up again the next time you boot.
The processes which will start up when you boot are listed in:
/etc/rc.d/init.d
(The contents of the directory /etc/rc.d/rc5.d are what will start up when
you go into run level 5 which is your default when you boot - x windows
starts. Entries in this dir are actually symbolic links to the "real"
things in init.d directory. The Sxx and Kxx numbers in front of the
process names indicate the order in which they will be started up.)
Now, you could always use the quick and dirty brute force method:
rm the critters from rc5.d (and or init.d), but I don't think you're
quite that desperate to get rid of them RIGHT NOW.
You could also unistall a package using rpm if you knew the package name
(and if that package didn't have anything else you needed) -
e.g. rpm -d apache* should uninstall the web server)
However, the more general and elegant way to control what does get
started from /etc/rc.d/... is to use a tool. There are two such tools
you can use: linuxconf (gui) and chkconfig (non-gui).
I suggest you try linuxconf for most of your system management tasks.
To turn off/on services:
linuxconf ==> Control ==> Control Panel ==> Control Service Activity
The list of all the services will appear in the window on the right.
double-click on the service. A window pops open.
Clicking on the "Automatic Startup Enabled" button enables/disables start
up of that service. Note that you also get a description of each
service in this window. Then click on "Accept" (note that you can
immediately start or stop a service with the Start and Stop and Restart
buttons.)
The other (non-gui) tool is: chkconfig.
chkconfig --list will list what services you have.
man chkconfig will give you the syntax for the rest.
Enjoy!
