RE: [PLUG] Unneeded programs running on startup
|
Looks like you have a RedHat system.
Kudzu is Redhat's program that looks for new hardware on start-up. It
generally works well and only runs on start up (can be helpful if you add
new hardware, otherwise, it doesn't do much and I don't think that it is a
security risk).
atd is the at-daemon. You can use it to schedual commands/programs to run
at certain times. It is like crond (but cron will run things every
minute/hour/day and not at 11:39:45 pm on a certain day).
sshd is the program that waits for ssh client to connect to. Not useful
unless you will be ssh-ing into your machine.
sgi_fam I think is part of fam which plugs into the kernel to let programs
know when directories have been updated. Can be useful, some programs
require it (galeon or nautilus I think, but, not sure).
apmd might be useful as I think it is the program that shuts off the monitor
and hard drives after a certain amount of time. Unless you are using this
as a server (which it doesn't sound like you are) this is actually helpful.
pcmcia is probably useless for you, unless you have a laptop.
nfslock you probably don't need either (unless you are using nfs for any
reason).
Webmin can be useful, since, it is a web based way to reconfigure your local
machine. I usually use it for remote machines.
tripwire is a firewalling type software. I don't know too much more about
it than that. It might only be intrusion detection.
that should give you a start on some of the items below. as is the case
most of the time, many of those you will use but not know it. I think that
xinetd may be needed, but, sendmail is probably not (unless you are using
your machine as a mail server).
good luck

Subject: [PLUG] Unneeded programs running on startup
Hello fellow PLUGgers !
Discovered a logging file under /var/spool/mail called "root".
Seems it's been running since long before I ordered my Linux
PC. And it's still watching my efforts ... Several Linux
programs seem to be running (anacron, crond, tripwire, sshd,
sgi_fam, sendmail, and logwatch appear in the file).
So I probed further. I looked at "Service Configuration" and
found that the following files run on startup:
anacron, apmd, atd, autofs, crond, gpm, iptables, isdn,
keytable, kudzu, linuxconf, lpd, netfs, network, nfslock,
ntpd, pcmcia, portmap, random, rawdevices, reconfig, sendmail,
sgi_fam, sshd, syslog, webmin, wine, and xinetd.
Some of these are clearly not needed for my computer:
apmd, pcmcia, xinetd, webmin, ntpd, portmap ...
I haven't been able to find out much about:
atd, sgi_fam, sshd ...
Which ones of these are left over from a previous incarnation
of my Linux PC (either the machine or the hard drive) and can
be safely jettisoned ? How do I do that ? If I stop them
under the Service Configuration menu and then save the changes,
will they stay stopped ? Or will they come back to life a la
Windows ?
After searching on each of these and briefly reading what I
found, I get the uneasy feeling that my machine is blabbing
all over town ... especially with all the mail messages
that the log says it's been sending.
Until I hear more, I think I'll just unhook the Linux PC's
modular telephone plug ...
Best regards,
George Langford
