Turning off unneeded FC1 processes

Hi everyone,

I just did a server/minimal install on an old white box using FC1. I noticed a number of processes running in 'ps ax' and was wondering which I could safely turn off:

Code:

  PID TTY      STAT   TIME COMMAND
    1 ?        S      0:06 init [3]  
    2 ?        SW     0:00 [keventd]
    3 ?        SW     0:00 [kapmd]
    4 ?        SWN    0:00 [ksoftirqd/0]
    6 ?        SW     0:00 [bdflush]
    5 ?        SW     0:00 [kswapd]
    7 ?        SW     0:00 [kupdated]
    8 ?        SW     0:00 [mdrecoveryd]
   12 ?        SW     0:00 [kjournald]

 2581 pts/0    R      0:00 ps ax

The box is going to be a simple testing server for an apache/php/postgresql platform. I see a whole lot of stuff turned on in ntsysv and was wondering someone could suggest what I could turn off. I already figuring on turning off portmap and gpm but maybe you guys can suggest some more. Here's my currenet ntsysv setup:

Code:

[*] acpid[*] anacron[*] apmd[*] atd[*] autofs[*] crond[*] gpm[*] httpd    [*] iptables
[ ] irda[*] irqbalance[*] isdn[*] kudzu[*] microcode_ctl[*] netfs[*] network 
[ ] nfs[*] nfslock[*] pcmcia[*] portmap[*] postgresql[*] random[*] rawdevices[*] rhnsd  
[ ] saslauthd[*] sendmail
[ ] smartd[*] sshd[*] syslog
[ ] yum

PS: smartd fails when I try to start or stop it so I just turned it off already.

Thanks so much for the help!!!

If you aren't and/or don't want anyone to log in remotely you can disable sshd. But thats all I believe that can be safely shut off without endangering your network maybe sendmail but you may need that to test mailto functions in php. ip2tables is your firewall so thats a personal choice. But thats all I would shutdown.

Okay, cool. I'll turn off iptables since my box is behind a firewall and on a LAN I can trust. Thanks for the input, although if anyone else thought I could trim the box down further that'd be cool.

you don't need apmd and acpid... one or the other should work... probably apmd since it's an older box... irqbalance is for multiple processors AFAIK...

[*] acpid[*] anacron[*] apmd[*] atd[*] autofs[*] crond[*] gpm[*] httpd [*] iptables
[ ] irda[*] irqbalance[*] isdn[*] kudzu[*] microcode_ctl[*] netfs[*] network
[ ] nfs[*] nfslock[*] pcmcia[*] portmap[*] postgresql[*] random[*] rawdevices[*] rhnsd
[ ] saslauthd[*] sendmail
[ ] smartd[*] sshd[*] syslog
[ ] yum

OK, from this list you can turn off acpid, apmd, atd, autofs, iptables, irqbalance if the computer has a single CPU, isdn, netfs, nfslock, pcmcia, portmap, rhnsd. Try to start smartd as this will monitor SMART functions on you hard-disk(s) and you can know in advance any problems that might hit you hdd. It saved my bacon several times. Edit /etc/smard.conf to fit your needs.

Wow, thanks a lot for that info! With Linux being so modular it makes sense that I can strip the box way down and squeeze every bit of performance out of it! Thanks again.
