Below is the results of what came up when I ran TOP on my dedicated server. Can somebody tell me if any of these services are not necessary? I would like to stop anything that I don't really need.

Any advice would be greatly appreciated.

Maybe stop all those httpd's :D :confused: :cartman: :rolleyes:

Do you have any idea how or why so many are running?

Does just one need to be ran the whole time?

How can get keep so many of them running in the future?

I take it that crond is a cronjob? If so, how can I tell what it is? I haven't set any of them up on my server and am concerned now.

Do you use this server for web hosting? I mean like charge people for it?

I wouldn't be too concerned about any of those services. When you start your web server it will start a number of processes. crond is the cron daemon that should always be running, unless you are never going to have any cron jobs.

Things to be concerned about are high load (it's nice for the load to be below 1 at all times) and Swap Usage.

Hi!
I do not think there is anything to worry.
These processes are regular processes.

Have a great day :)

No way :)

I'm just using it to start learning Linux and to host a few very low traffic websites I have.

As the others have said all those are normal processes the httpd are Apache processes you will normally have several open depending on how many people are connected to server viewing web pages etc.

I suggest you get a good book and learn what you machine is doing.

You load looks good so there is no reason to worry about killing any processes now.

Thanks for the help. As you suggested, I'm going to have to get a good book to learn about this stuff.

Should I be concerned about all those httpd processes running? Is there supposed to be just one running at all times or is there one running for every visitor who is on the server looking at a web page?

Sorry for the stupid questions :)


JTM

Every visitor will spawn a new one. No concern at all.. I suggest you get Linux Unleashed it covers Apache Bind FTP etc ...

Look in the httpd.conf config file. In the top third you should see section that looks like:
#
# Server-pool size regulation. Rather than making you guess how many
# server processes you need, Apache dynamically adapts to the load it
# sees --- that is, it tries to maintain enough server processes to
# handle the current load, plus a few spare servers to handle transient
# load spikes (e.g., multiple simultaneous requests from a single
# Netscape browser).
#
# It does this by periodically checking how many servers are waiting
# for a request. If there are fewer than MinSpareServers, it creates
# a new spare. If there are more than MaxSpareServers, some of the
# spares die off. The default values are probably OK for most sites.
#
MinSpareServers 2
MaxSpareServers 10

#
# Number of servers to start initially --- should be a reasonable ballpark
# figure.
#
StartServers 2

#
# Limit on total number of servers running, i.e., limit on the number
# of clients who can simultaneously connect --- if this limit is ever
# reached, clients will be LOCKED OUT, so it should NOT BE SET TOO LOW.
# It is intended mainly as a brake to keep a runaway server from taking
# the system with it as it spirals down...
#
MaxClients 150


The comments are pretty much self-explanatory.

Your httpd daemons look fine. The only daemon I would question is apmd - does your dedicated server need power management? I know that Linux is rather aggressive in running that daemon, whether it is needed or not. You should look into what it is used for and decide whether or not to keep it.

Also, I notice you're running webmin. Be sure to keep up with the security updates for it. At the very least, move webmin off of its default port, and have it listen on a port of your own choosing. While that won't improve the security of the webmin code, it will at least save you from most of the port scans that are looking to exploit it.
