  1. Then if you're gonna try to turn services off, do one at a time in between reboots.

     

    good advice

     

    Here is a brief description of some of the services that I found somewhere on the web

     

    anacron

    Related to the 'cron'-daemon. 'cron' runs tasks like system maintenance at certain times, but skips them if the system isn't running at that time. That's where 'anacron' comes in: it checks delayed 'cron'-tasks at boot-time and executes them. If your machine doesn't run all the time, you should leave it enabled. Optional. Doc: man anacron

     

    apmd

    The Advanced Power Management BIOS Daemon. Only needed if your computer runs on battery. Optional. Doc: man apmd

     

    arpwatch

    Keeps track of ethernet/ip address pairings. Usually not enabled. Optional. Doc: man arpsnmp

     

    atd

    The "At Daemon". Manages scheduled jobs. Related to crond. Essential. Doc: man atd, man at

     

    autofs

    Controls the automount daemon (note: this has nothing to do with 'supermount'). Usually not enabled. You might need it if you want to mount network-shares automatically. Optional. Doc: man autofs, man automount

     

    bootparamd

    Used to provide boot-information to diskless clients. You probably don't need this vulnerable service. Usually not enabled. Optional. Doc: man bootparamd

     

    crond

    The Cron Daemon. Manages repeated tasks. Related to atd. Essential. Doc: man crond, man cron

     

    gpm

    General Purpose Mouse Daemon. Necessary only if you want to use your mouse on the console (not xterms). If you only work within X it's better to turn it off, incompatibilities with X are a known issue. Optional. Doc: man gpm

     

    httpd

    The daemon necessary to run the Apache web-server. If you do not intend to run a web-server, turn it off: it uses a considerable amount of system resources and makes your box vulnerable to outside attacks if not configured properly. Optional. Doc: man httpd.

     

    inet(d)

    This handles dial-in services like ftp, pop3 and telnet (these three are enabled by default). If you only dial-out turn it off!. In its default setting it essentially invites anyone who knows your IP to launch an attack at your box. If you want to use it however, have a look at '/etc/inetd.conf', '/etc/hosts.allow', '/etc/hosts.deny' and install the tcp-wrappers.rpm. Optional. Doc: man inetd, man hosts_access and man tcpd.

     

    keytable

    Loads the selected keyboard map as set in '/etc/sysconfig/keyboard'. Usually enabled. Essential for users with non-US keyboards. Doc: man loadkeys

     

    kudzu

    Detects and configures new or changed hardware during boot. If you turn it off your box will boot faster. You can then run it from within the system. Usually enabled. Optional. Doc: man kudzu

     

    linuxconf

    This is not needed to run LinuxConf. This service is used to configure a linux box remotely with a browser. Most linux users will probably never use this. If not needed, it's safe to turn this off. Usually enabled. Optional. Doc: '/usr/lib/linuxconf/help.

     

    lpd

    The "Line Printer Spooler Daemon". Needed for printing. Usually enabled. Optional. Doc: man lpd

     

    netfs

    Network Filesystem Mounter. Generic service. Needed for mounting NFS, SMB and NCP shares on boot. Usually enabled. Optional. Doc: man mount

     

    network

    Activates all network interfaces at boot time by calling the scripts in '/etc/sysconfig/network-scripts'. Usually enabled. Essential. Doc: man ifconfig and the appropriate documentation for the initiated interfaces.

     

    nfslock

    Starts and stops the NFS file locking service. If you have no idea what this means, you can turn it off. Usually enabled. Optional. Doc: man nfs.

     

    numlock

    Locks NumLock key at init runlevel change. Usually enabled. Optional. No docs.

     

    pcmcia

    For laptop users only. Optional. Read the script.

     

    portmap

    Needed for Remote Procedure Calls. Portmap can be a huge security risk if not properly configured. It should only be needed for NFS or NIS services, if you don't use these then turn it off. Usually enabled. Optional. Doc: man portmap

     

    postfix

    This is the "Mail Transport Agent", something like sendmail. If you use Netscape Mail, KMail you can turn it off. Usually enabled. Optional. Doc: man postfix, '/usr/doc/postfix-[version]/html/index.html'

     

    random

    Random Number Generating Daemon. Needed for security. Essential. Doc: man 4 random

     

    routed

    Network Routing Daemon. Don't use this unless you really need it and don't use this if you have a dial-up connection. Optional. Doc: man routed

     

    rstatd

    The kernel statistics server (advanced networking stuff). Usually not enabled. Optional. Doc: man rpc.rstatd

     

    rusersd, rwalld, rwhod

    Provide several services useful when running a server. Usually not enabled. Optional. Doc: man-pages

     

    smb

    Needed for running SAMBA, the "Server Message Block Protocol Server". It allows you to provide network services to Windows clients and access shares on those machines from your GNU/Linux box. Usually not enabled. Optional. Doc: man samba, MUO pages on configuring SAMBA.

     

    syslog

    System Message Logger. Essential. Doc: man sysklogd

     

    usb

    Daemon for devices on the Universal Serial Bus. If you don't use such devices, you can turn it off. Usually enabled. Optional. For more check the files in /usr/src/linux/drivers/usb (you'll need the kernel-sources.rpm for this)

     

    xfs

    X Font Server. If you don't load this then you'll have to manually set the font paths in '/etc/X11/XF86Config' and use and external TrueType font server like xfstt. Usually enabled. Essential for X users. Doc: man xfs

  2. Guarddog was unable to read the file at /etc/rc.firewall as being a Guarddog firewall.

    This probably means that this file in not actually a Guarddog firewall.

    This is not a problem, but please note that if you exit Guarddog via the 'Ok' button this file will be overwritten.

     

    If I recall my Guarddog installation correctly, selecting OK and overwriting the original file was what I did with no ill effects. You have no firewall installed other than iptables, and Guarddog is an iptables front end.

  3. I am not aware of any performance tweaks you can make to XF86Config4, but I have only been running Mandrake a few months. Perhaps someone else here has a suggestion?

     

    There is another software application you can download called Yanc, but I'm not sure it offers anything beyond what you see in nvidia-settiings

  4. Well, the CMOS battery is a possibility, and it would (presumably) be inexpensive to replace.

     

    I got a network timeout when I tried your link, but from your response it sounds like you are dealing with a SFF box. I have been intrigued with this type of hardware lately....Is most of the hardware proprietary?

  5. I had Mandrake 10 installed on a harddisk that I later retired. I forgot about the drive and its contents until recently when I built a computer out of spare parts. My collection of spare parts included the retired drive. EVERY piece of hardware was different from the original install, and Mandrake still booted. Amazing.

     

    I then wiped it clean and installed Windows 98 so my 6 year old daughter could play Barbie. So sad. :)
