====== Slackware Installation and Configuration Tips ==
===== Abstract ==

Purpose of the document is the descpiption of ever repeating install and config procedures at a central place.

Because Slackware Linux uses most packages in their pristine forms, the documentation here is targeted mainly to this distro. The order of this document is more or less followning the natural installation order of a Slackware Linux system.

Examples of sourcefiles in this doc should specify their path (eg /etc/rc.d/rc.local) as a comment at the beginning.

===== Metadata ==
==== Third-party Programs ==

For additional Software first look in the [[slackmirror>slackware/extra/|extra directory]] of a [[http://www.slackware.com/getslack/|Slackware mirror]]. Use the ''installpkg'' command to install one of those packages.

Second check out www.linuxpackages.net or www.slacky.eu (Also installed with ''installpkg''). FIXME Are http://slackware.com/~alien/ and http://slackware.com/~rworkman/ worth a look too?

Third look at www.SlackBuilds.org. The [[http://slackbuilds.org/howto/|SlackBuild Usage HOWTO]] tells you more.

If you can get 'only' the source code of a programm, than you should prefer [[commands#checkinstall]] to the normal ''./configure - make - make install'' procedure. Thus the software can be cleanly removed later or distributed ot oter Slackware-Boxes.

Self-build or third-party programs where no slackware package is available go to ''/usr/local/<programname-version>''. Then make a symlink ''<programname> -> <programname-version>''. See also: [[http://www.openaddict.com/documents/Linux-Filesystem-Hierarchy/usr.html|Linux Filesystem Hierarchy]], [[wpde>Filesystem_Hierarchy_Standard#.2Fusr.2Flocal_:_lokal_installierte_Programme|Linux Filesystem Hierarchy (german)]]

Another Tip: The compressed file ''MANIFEST.bz2'' on the distro contains a list of all files wich all packages contain and install to the system. [[slackmirror>slackware/slackware/MANIFEST.bz2|Example]]

==== Upgrading and Keeping Slack up to date ==

==== Linux Application Installation and Configuration Tips ==

See [[Slack App Tips]]

===== Slack Installation ==

[[slackmirror>slackware/Slackware-HOWTO|Original Slack installation howto]]

As of Slack 12.0 making boot disks is obsoletete. The description is kept in [[Slack tips attic]] for reference

==== Boot ==

UEFI systems might need some tweaking to boot: [[slack on uefi]]

Since Slack 12.0 the default Kernel to select is hugesmp.s (hugse.s on 14.2 64Bit)

<del>Select kernel: Since Slack 10.2 I prefer ''bareacpi.i'' over the default ''bare.i'' for standard IDE Systems. For my SCSI-PC I use ''adaptec.s''. ''lspci -v'' will help to select the suitable kernel.</del> (obsolete)

<del>With bare.i & adaptec.s I always enable APM in ''/etc/rc.d/rc.modules'' by uncommenting the line ''/sbin/modprobe apm'' (later). This switches the system off completly after shutdown (Fans are turned off too). ''lsmod'' shows if APM is working. With bareacpi.i APM in not necessary.</del> (obsolete)

Keyboard layout: quertz/de-latin1-nodeadkeys.map

For netword based setup, after login as root, type ''network''!

==== Partitioning ==

Use cfdisk. Make at least 3 Partitions for Swap, / and /home.

=== Swap ==

If you have plenty of RAM than Swap is not so important, but create a Swap partition anyway, probabliy with the //same size as the RAM//. Otherwise a fstab may not be created.

Further reading: How big should my swap space be? See [[http://www.linux.com/news/software/applications/8208-all-about-linux-swap-space|All about Linux swap space]]

=== / ==

This is where the packages of the distribution go. E.g. a full install of Slack 13.37 needs about 6.5 GB, so 8-9 GB is a good size for this partition

=== /home ==

Is for all data which has to survive a Slackware update. Use the rest of available disk space for this partition.

See [[slack_upgrade]] how to use this partion also for e.g. /usr/local

==== Setup ==
=== Tips ==

Note: [Alt][Fx] gives another console while setup is running. Good for testing puposes

If you want to reuse old partitions which contain already data, eg for /home /home/share you can specify them here, but  **don't** select to format them!

<del>A note on network boot: It worked with the single line ''/mnt/cdrom/slackware *(ro,sync)'' in ''/etc/exports'' on the server and at the promt "What is the Slackware source directory" ''/mnt/cdrom/slackware''. Of course, the install DVD/CD has to be mountet in the cd-drive of the server before</del>

Package Series Selection Recommendations: If disc space is sparse deselect E (Emacs), F (FAQ's), K (Kernel Source), T  (TeX typesetting language), TCL (Tcl/Tk/TclX scripting languages and tools) & Y (Classic text-based BSD games). But //select// KDEI (KDE i18n -- why??) (and remove unnecessary languages later)

:!: In order to track //all// local configuration changes, when the setup program asks to configure the network, switch to another console and make a cp of /mnt/etc

=== Setup Example ==

  * Keymap: qwertz/de-latin1-nodeadkeys.map (I think this has to be specified again here)
  * Root Partition: /dev/hda2
  * Format /dev/hda2 with check and reiserfs
  * Optional: Add existing FAT or NTFS Partitions to fstab: yes, as /ntfs-c
  * Install from Slack-CD, Scan auto
  * Package series: all, including KDEI
  * Prompting mode: full; now the packages will be installed, this takes some time
  * Bootstick: Optional
/*
  * Install Linux Kernel: From CDROM! (Dont't skip)
  * /dev/modem -> /dev/ttyS0
  * hotplug: yes; in case of problems: /etc/hotplug/blacklist /etc/modprobe.d/blacklist
*/
  * Lilo
    * Expert mode
    * Begin
      * <del>Optional Kernel Parameters: hdc=ide-scsi, (hdc: secondary master, see [[http://www.slackbook.org/html/installation-partitioning.html|slackbook]], [[tldp>sag/html/hard-disk.html|sag]] or ''ide_info /dev/hdX'' shows where the burner is)</del>
      * Use UTF-8 Text Console: Yes (for non-english users)
      * Frame Buffer: 1024x768x64k
      * Use UTF-8 Text Console: YES 
      * Lilo target: MBR (/dev/hda)
      * Timeout: 5s
    * Linux: Select Linux Partition: /dev/hda2
    * Install
    * Conifg can be changed later with ''liloconfig'' or directly by editing ''/etc/lilo.conf'' & re-installing th boot loader with the command ''lilo''
  * Mouse: /dev/mouse: ps2 (recommended & works also for touchpads. Creates the symlink /dev/mouse -> /dev/input/mice )
  * gpm: yes
  * Configure Network: yes (or later with ''netconfig'')
    * Hostname: ilse
    * Domainname: local
    * IP Address: static IP
    * Ip-Adresse: 192.168.0.1
    * Netmask: 255.255.255.0
    * Gateway: No
    * Nameserver: No
  * Startup services: Keep default or activate what you need
  * custom screen fonts: no
  * Hardware clock set to UTC: yes
  * Timezone: Europe/Berlin
  * Default Window Manager: xinitrc.xfce
  * Root Password: yes
  * Exit

=== Note on netconfig ==

If you use ''netconfig'' to setup a static IP connection it changes the following files:
  /etc/resolv.conf
  /etc/rc.d/rc.inet1.conf
  /etc/HOSTNAME
  /etc/hosts
  /etc/networks

===== After Install Config ==

Bevore changing confiuration files, it is recommendable to keep a copy of the original file with the extension ''.org''. Eg: ''cp /etc/ntp.conf /etc/ntp.conf.org''. This allows to go back to the original configuration in case of failure and makes it easier to introduce your local changes to the new config files after an operation system upgrade (by using [[diffupgrade]]).

Sometimes there is already an identical copy of the config file supplied. Eg. in /etc/apache/ the files httpd.conf & httpd.conf.default are initially the same. In this case just make a symlink: httpd.conf.org -> httpd.conf.default. Thus a  ''find -name '*.org''' will always give you an overview of modified config files.

==== (auto)mount & /etc/fstab ==
=== Users and Groups ==

On Slack userer can be added to the system with the ''adduser'' command. Make sure that local users are added to the groups audio, video, cdrom, plugdev. (adduser provides an option to preselect the most common groups.)
This avoids access right problems with various multimedia apps like Xine, Vlc or Skype.

=== CDROM & Floppy ==

FIXME Check: For command line (un)mounting the things below (pre Slack 12.0) still apply, i.e. you still need entries for cdrom and dvd devices:

  * If required copy line /dev/cdrom and replace cdrom with dvd and check if Symlink /dev/dvd -> /dev/hdc or similar exists
  * Replace ''owner'' with ''users'' at line /dev/cdrom /dev/dvd and /dev/fd0 to allow a normal user to (un)mount such a device
  * Add a line for usb drives at the end

:!: Since Slack 11.0 the cdrom-burner (kernel scsi-emulation in lilo) is not found in eg /dev/hdd anymore, but in eg /dev/sr0 => This means that a Symlink /dev/cdrom -> /dev/sr0 and not /dev/cdrom -> /dev/hdd. You get that hint when you try to mount eg ''# mount -t iso9660 /dev/cdrom  /mnt/cdrom/'' as root.

=== USB Drives ==

Since Slack 12 which uses HAL USB drives can mounted automatically if you stick to KDE, GNOME, or Xfce. They provide an automount feature via DBUS/HAL. Just add the usernames of the users to the plugdev group in /etc/group, reload configuration with ''/etc/rc.d/rc.messagebus reload'' and restart KDE. No changes to fstab are necessary.

If you also want to mount in the traditional way with the command line, than add a line for USB drives to /etc/fstab, eg: ''/dev/sda1  /media/memory0 auto  users,noatime,async 0 0''. The entries in fstab are respected by HAL. 'users' means that every user can mount and also a different user can unmount. 'noatime,async' are for conserving flasch memory lifetime. See [[slackmirror>slackware-12.0/CHANGES_AND_HINTS.TXT]] and [[http://www.linuxquestions.org/questions/showthread.php?t=566948&page=2|linuxquestions.org]]

=== fstab Example ==

<code>
/dev/hda1        swap             swap        defaults         0   0
/dev/hda2        /                ext3        defaults         1   1
/dev/hda3        /home            ext3        defaults         1   2
/dev/cdrom       /mnt/cdrom       auto        noauto,users,ro  0   0
/dev/dvd         /mnt/dvd         auto        noauto,users,ro  0   0
/dev/fd0         /mnt/floppy      auto        noauto,users     0   0
devpts           /dev/pts         devpts      gid=5,mode=620   0   0
proc             /proc            proc        defaults         0   0
/dev/sda1        /media/memory    auto        users,noatime,async 0   0
</code>

==== /etc/profile.d/lang.sh ==

<code bash>
export LANG=de_DE.utf8
#export LANG=de_DE@euro #obsolete
</code>

This localizes many apps, eg Fluxbox Java, editors and pagers.

Note that for viewing and editing text files in a termial emulator window, both the emulator and the viewer/editor need to be UTF-8 aware.

Examples for applications which respect UTF-8 are the terminal emulator ''terminal'' (from the Xfce project), the pager ''less'' and the edior ''vim''.

<del>Dies beeinflußt auch das default character encoding von kate und kwrite unter Kde. Wählt man zB LANG=de_DE@euro, so ist das default encoding ISO-8859-15</del>

''locale -a'' shows all possible LANG values

==== /etc/profile.d/local.sh ==

<code bash>
#!/bin/sh
# default settings for every day command line usage
# may be overwritten in /home/<username>/.profile

# for CVS:
export EDITOR='/usr/bin/vim'

# for crontab -e
export VISUAL="$EDITOR"

# for mysql and man
#export PAGER='/usr/bin/most'
export PAGER='/usr/bin/less -iR'
# -i: case insesitive search; -R: colorize output (for colordiff)

# conveninence shortcuts:
alias   o="$PAGER"   # default pager
alias  oo=/usr/bin/view
alias   e="$EDITOR"  # default command line editor
alias  ge='kate -u'  # default gui editor
alias  vt='ls -hltrF'# directory listing time sorted newest last
alias  ll='ls -alF'  # detailed directory listing
alias  ..='cd ..'    # go to parent directory
alias ...='cd ../..' # go to parent of parent directory
alias cal='cal -3m'  # calendar: Start on Monday & display 3 Months
alias  bc='bc -l'    # calculator: preload mathlib, scale=20
</code>

==== ~/.profile ==

Optional conveniences, dependent of the individual users taste go to ''$HOME/.profile''. Here an example:

<code bash>
#!/bin/bash
# shebang only necessary for text coloring in editor

# use jedit instead of kate as gui editor:
# overwrites /etc/profile.d/local.sh
# only if jedit is installed & favored
alias ge='jedit'

# For per user scripts and commands:
# export is not really necessary here, because PATH is already exported in
# /etc/profile
export PATH=$PATH:~/bin

# Subversion log:
alias hglog='hg glog | o -S'
</code>

==== xorg.conf ==

No config necessary any more. (Otherwise see [[xorg_tips#etc_x11_xorg.conf|xorg_tips->etc_x11_xorg.conf]])

==== Alsa/Pulse Sound ==

see [[sound#Basic setup]] and as of 14.2 set mplayer to use [[sound#select_output_driver|pulse]] as output device

==== Harddisk Standby ==

Disable ''-- MARK --'' timestamp appearing in a 20 minute interval in /var/log/messages. From [[http://ldp.bootet.net/HOWTO/Battery-Powered/methods.html#SYSKLOGD|Battery powered Howto]] & [[http://l0k1.free.fr/aolsfaq.html#XX85|alt.os.linux.slackware Faq]]
<code bash>
#/etc/rc.d/rc.syslog :
...
#/usr/sbin/syslogd
/usr/sbin/syslogd -m 0
...
</code>

FIXME Check with kernel 2.6: Harddisk standby after a timeout of eg 20 min in /etc/rc.d/rc.local:
  hdparm -S 240 /dev/hda
Values from 1 - 240 specify multiples of 5s. From [[man>hdparm|man hdparm]] & [[http://ldp.bootet.net/HOWTO/Battery-Powered/methods.html#HDPARM|Battery powered Howto]] and. Operation may not supported on SCSI disks. Doesn't seem to work with SCSI drives (eg. /dev/sda)

==== ACPI ==

FIXME As of Slack 12.2 this section seems to have become obsolete and needless.

To get battery control on laptops (eg in KDE) on Slack12 add this to /etc/rc.d/rc.modules :

<code bash>
/sbin/modprobe ac
/sbin/modprobe button
/sbin/modprobe battery
/sbin/modprobe processor
/sbin/modprobe thermal
/sbin/modprobe fan
/sbin/modprobe video
/sbin/modprobe container
</code>

[[http://www.slackforum.de/forum/index.php?t=msg&goto=17922|Source]], [[http://www.columbia.edu/~ariel/acpi/acpi_howto.html#config_reference|description]], [[tldp>HOWTO/ACPI-HOWTO/loadmodules.html|more]]

==== Create and install an Initrd ==

See [[slack_initrd]]

==== Remote Login ==

For remote Login via window manager see [[xorg_tips#kdm|xorg_tips->kdm]]

To start remote xapps via ssh enable X11Forwarding on the (application-)server side by uncommenting it somewhere in /etc/ssh/sshd_config:
<code bash>
#X11Forwarding no
X11Forwarding yes
</code>
Additionaly log into the server with ''ssh -Y''.

==== Terminal Emulator Config Example ==

As of 2009-05-05 terminal emulator of the Xfce window manger (called "Terminal", alternatively started with ''terminal'') is recommended. It supports multiple tabs, transparency and respects UTF-8.

For a start here is a resonable configuration file for ''terminal''. Copy it to : ''$HOME/.config/Terminal/terminalrc'':

<code ini>
[Configuration]
BackgroundMode=TERMINAL_BACKGROUND_TRANSPARENT
CommandLoginShell=TRUE
FontAntiAlias=FALSE
FontName=Fixed 12
MiscDefaultGeometry=80x62
MiscMenubarDefault=FALSE
MiscConfirmClose=FALSE
</code>

Obsolete settings for mrxvt, aterm and xterm are at [[Slack Tips Attic]].

==== Remove unnecessary Language Packages ==

Rename the language packages you need in /var/log/packages and run ''removepkg ...''. Then re-rename the necessary packages to their original name again. Example for keeping only German (and default Enlish) :

<code bash>
cd /var/log/packages
mv kde-i18n-de-3.5.4-noarch-1 _kde-i18n-de-3.5.4-noarch-1
mv koffice-l10n-de-1.5.2-noarch-1 _koffice-l10n-de-1.5.2-noarch-1
removepkg kde-i18n-* koffice-l10n-*
mv _kde-i18n-de-3.5.4-noarch-1 kde-i18n-de-3.5.4-noarch-1
mv _koffice-l10n-de-1.5.2-noarch-1 koffice-l10n-de-1.5.2-noarch-1
</code>

Alternatively deselect the KDEI package series during setup and install the necessary language packages later manually with installpkg from the CD.

===== Internet Connection and Networking ==

For Internet Connection wired or WLAN, with DSL router, with DSL modem or with analog modem and for Firewall setup see [[network tips]]

===== Printing ==
==== Local Printer Setup ==
=== Use Cups as Printing System ==

Check if cupsd is running with ''ps aux | grep cups'' or point browser to http://localhost:631 . If cupsd is not running, make rc.cups executable and start cupsd with ''/etc/rc.d/rc.cups start''

On http://localhost:631 and your root password you can add local connected printers. Note that as of Slack12 an USB printer has to be connected (and switched on) in order to be selectable.

=== Optionally install Turboprint ==

To setup Turboprint download the latest 1.x version from http://turboprint.de (keyfile-readmy claims to work only with 1.x versions of tp) & unpack. Dont change ''system.cfg'' (using /usr/local instead of /usr won't work with cups!). Install as root with ./setup . This may last a long time. Output should be similar to

  Program Files /usr/share/turboprint
  Commands      /usr/bin
  Spool Dir     /var/spool/lpd
  Man Pages     /usr/share/man
  Log Files     /var/log
  Temp          /tmp
  Cups Drivers  /usr/share/cups/model
  Cups Filters  /usr/lib/cups/filter

To setup printers start (x)tpsetup as root. xtpsetup  needs X, so start it with ''su -c $(which xtpsetup)'' or something like
  xhost +
  su root
  export DISPLAY=:0.0

Click on 'add' to add a new printer. To setup an USB printer use /dev/usb/lp0 as output in xtpsetup

To register keyfile, save the keyfile somewhere, start xtpsetup as root, press register -> install keyfile and select keyfile in dialog box.

Turboprint manual: [[http://turboprint.de/german/manual/turboprint.html|online]] [[file:///usr/share/turboprint/doc/html/turboprint.html|offline]] / Cups manuals: [[http://cups.org/sam.html|for admins]] [[http://cups.org/sum.html|for users]]

=== Useful commands ==

  lpinfo -v
  lpstat -p -d # ?
  lpadmin -d printername # set default printer see cups admin manual

=== Open Questions ==

FIXME On ingolf at 2006-11-28 hat been problems with parallel port, cups said "Parallel port busy; will retry in 30 seconds..." and the printer (S500) stopped working. Searching google brought: http://www.luga.at/mailing-lists/luga/2006/07/msg00039.html. So I uncommented the "### PC parallel port support ###" section in /etc/rc.d/rc.modules and set ''/sbin/modprobe parport_pc io=0x378 irq=7''. Lets see, if it works from now on...

==== Network Printer Setup ==

On the client side (this is the host which wants to use the printer, but where the printer is not connected locally) just make sure, that cupsd is running. No more changes are necessary.

On the server side, where the printer is connected via USB or printer cable, first make a local printer setup (see above) Turboprint needs only to be installed on the server side.

Than edit /etc/cups/cups.conf:
<code bash>
#BrowseAddress @LOCAL
BrowseAddress @LOCAL
<Location>
  ...
  #Allow From 127.0.0.1
  Allow From @LOCAL
</Location>
<Location admin> :
  ...
  #Allow From 127.0.0.1
  Allow From @LOCAL
</Location> :
</code>
Die ersten beiden Änderungen bewirken das remote cupsd's die lokalen Drucker erkennen können. Wird die 1. Änderung wieder Rückgängig gemacht, so vergessen die Clients auch die Drucker auf ingolf wieder.

Die 3. Änderung bewirkt, daß die Administration auch von einem entferten Rechner erfolgen kann @LOCAL heißt nur das lokale Netz, keine Dial-up Broadcasts (siehe cupsd.conf)

Restart cupsd then!

==== Printer config Frontends ==

Note: This needs to be verified  --- 2006-11-07 14:50

=== Frontends ==

  * System-wide config
    * (x)tpconfig as root
    * http://localhost:631/admin/
    * lpoptions as root
    * kde-controlcenter -> cups in admin-mode
  * user-config
    * (x)tpconfig
    * lpoptions
    * kde-controlcenter -> cups (as kprinter-default?)
    * kprinter

=== Rules ==

  * The [[http://localhost:631/admin|Cups Web-UI]] can install printers and set printer options. But this works only as root
  * (x)tpsetup can install printers and only be run as root.
  * (x)tpconfig can set printer options and do printer maintainance.
  * System wide settings can be done with (x)tpsetup/(x)tpconfig or Cups Web-UI. They respect each other.
  * Settings done with kde-controlcenter -> cups in admin-mode are probably sysem-wide but only for kprinter
  * Settings done with kde-controlcenter -> cups in user-mode overwrite kde-admin-mode but apply only for kprinter
  * lpoptions comes from cups and its settings are only used by lp and lpr commands
  * lpoptions as root sets system wide settings for lp and lpr
  * printer options set with (x)tpconfig probably apply only for lp and lpr too.

==== Open Questions ==

  * How interact xtpconfig as user with kprinter config dialog and with cups-config in kde-controlcenter and with lpoptions ?
  * How can the servicest of xtpconfig used, when turbopint is not installed locally? lpoptions? See also CUPS Software Administrators Manual
  * For buying a new printer http://www.linux.com/article.pl?sid=06/11/02/1515243 http://www.linuxprinting.org/suggested.html http://hplip.sf.net/ may help

===== Network Time Protokol NTP ==

See [[NTP]]

===== Shutdown ==
==== Allow Shutdown for normal Users ==

FIXME Change sudo config or suid /sbin/halt and symlink /usr/local/bin/shutdown -> /sbin/halt, /usr/local/bin/reboot -> /sbin/halt

==== Automate Shutdown with cron ==

Get system crontab file as root: ''crontab -l > cronbuffer''; Open cronbuffer with vim and add somesthing similar to the following lines:
<code bash>
...
# Run daily cron jobs not at 4:40 but at 18:00 every day:
0 18 * * * /usr/bin/run-parts /etc/cron.daily 1> /dev/null
...
# Daily Shutdown Mo-Fr at 18:10, Sa&So at 17:00, give user 5 Minutes to log out:
0  17 * * 5-0  /sbin/shutdown -h +5 "Weekend! Shutting down!"
10 18 * * 1-4  /sbin/shutdown -h +5 "Quitting time! Shutting down!"
</code>
(At this occasion the time of daily jobs is also changed to something more reasonable at daytime, assuming your computer is off at night. This makes the command ''locate'' work properly.)

Install your new crontab with ''crontab cronbuffer''. (Normally you could also use ''crontab -e'' to directly edit the crontab, but this did not work on Slack 11.0, don't know why.)

===== Backup with rsyncd ==

See [[becki/sources/beckibackup]]

===== NFS ==
==== Server Side ==
=== Quick & dirty ==

''/etc/rc.d/rc.nfsd'' must be executable. (''rc.inet2'' starts ''rc.nfsd'')

<code bash>
# file: /etc/exports
/home/becki/nfs  *(rw)
</code>

This allows any(''*'') client to mount the local dir ''/home/becki/nfs'' with read/write(''rw'') permission. [[http://www.slackbook.org/html/network-configuration-nfs.html|NFS is an unauthenticated protocol]].

=== User ID Mapping ==

Assume the same user on the client has user ID 1000, group ID 1000 and on the server user ID 1005, group ID 100 . With the settings in ''/etc/exports'' above, files created by the client on the server would have user ID 1000, groop ID 1000 ((''man exports'' -> User ID Mapping)). Hence permissions on the server need to be given accordingly (''chmod 777 /home/becki/nfs'').

If you want the files created by the client on the server with the IDs of the server, the following exports file is necessary:

<code bash>
# file: /etc/exports
/home/becki/nfs  *(rw,all_squash,anonuid=1005,anongid=100)
</code>

=== Restrictions ==

  /opt/ltsp  192.168.0.0/255.255.255.0(ro)

Restricts the dir ''/opt/ltsp'' to read only (ro) access to your localnet (which is 192.168.0.0-192.168.0.255 in the example).

  /tftpboot  *.somedomain.de(rw)

Restricts ''/tftpboot'' to read/write (rw) access to all hosts belonging to somedomain.de.


=== Allow root Access ==

  /opt/ltsp  willi(no_root_squash)

Root user from host "willi" can act on the server as root too. Dangerous, dont' use it. From [[man>exports(5)]]

==== Client Side ==

  mount -t nfs serverName:/home/becki/nfs /mnt/tmp

===== Fluxbox ==
=== Background Image ==

Call ''fbsetbg -r /home/becki/wallpapers'' for a //random// pic or ''fbsetbg -a /home/becki/wallpapers/aCertainImage.jpg'' once for only one //maximized// image. Both commands create ''~/.fluxbox/lastwallpaper''

Add ''session.screen0.rootCommand: fbsetbg -l'' to ''~/.fluxbox/init'' to get the bg-image at startup of fluxbox. ([[http://fluxbox.org/docbook/en/html/chap-bg.html|more]])

Alternatively, this crontab changes the background image every 10 minutes (-R ignores ~/fluxbox/lastwallpaper):
<code bash>
# MIN HOUR DAY MONTH DAYOFWEEK   COMMAND
*/10 * * * *  PATH=$PATH:/usr/X11/bin DISPLAY=:0.0 /usr/X11R6/bin/fbsetbg -R /home/becki/wallpapers &> /dev/null

===== FTP Server ==

Slack 11.0 provides vsftpd and proftpd as FTP servers. proftpd is uses because of oviously better documentation and apache-like config file.

  * Make ''/etc/rc.d/rc.inetd'' runnable
  * Activate the line containing 'proftp' by removing the comment '#' sign at the beginning in ''/etc/inetd.conf''
  * If ''/etc/rc.d/rc.inetd'' was not runnable before, you can savely comment out everything else in ''/etc/inetd.conf''
  * Start inetd by typing ''/etc/rc.d/rc.inetd start''

If you want to restrict to restrict the ftp users to their home dir, add the line
  DefaultRoot ~
to ''/etc/proftpd.conf''. More config templates and docu can be found in /usr/doc/proftpd-1.3.0/.
