Slackware Linux configuration

this is obsolete doc -- see http://doc.nethence.com/ instead

Installation

For a very minimal slackware installation, use slackinst (http://pbraun.nethence.com/doc/sysutils_linux/slackware_slackinst.html), otherwise get those sets installed (ADD + REC tags are enought),

D (gcc, make and kernel-headers)

# (K on second cdrom)

L (loads of libraries)

# (T on second cdrom)

# (X for a workstation)

# (XAP for a workstation)

Post-installation

You can login remotely by ssh as root by default.

Make it boot faster,

cd /etc/

cp lilo.conf lilo.conf.dist

vi lilo.conf

lba32

timeout = 50

lilo

Disable the time server, biff, auth,

cd /etc/

vi inetd.conf

#time stream tcp nowait root internal

#time dgram udp wait root internal

#comsat dgram udp wait root /usr/sbin/tcpd in.comsat

#auth stream tcp wait root /usr/sbin/in.identd in.identd

/etc/rc.d/rc.inetd restart

netstat -antpe --inet --inet6 | grep LISTEN

Create a wheeled (admin) user,

admin=adminuser

useradd -g users -G root $adminuser

passwd $adminuser

Now that the admin user has been created, you can clean-up the skeletons,

cd /etc/

mv skel/ skel.dist/

mkdir skel/

Either use 'timezone' or proceed manually,

cd /etc/

cat hardwareclock

#echo UTC > hardwareclock

ls -l localtime*

#ln -s /usr/share/zoneinfo/Europe/Paris localtime

Temporarily connect with DHCP (or copy/paste if you are on a serial terminal emulator) to fetch the network config scripts,

mkdir -p ~/bin/

cd ~/bin/

wget http://pbraun.nethence.com/scripts/sysutils/slack/config

wget http://pbraun.nethence.com/scripts/sysutils/slack/network.ksh

chmod +x config network.ksh

cp /etc/rc.d/rc.inet1 /etc/rc.d/rc.inet1.dist

chmod -x /etc/rc.d/rc.inet1.dist

./config

or just use,

netconfig

Secure SSH the SSH service,

cd ~/

mkdir -p .ssh/

cd .ssh/

vi authorized_keys

(paste your one-liner rsa or dsa public key here)

cd /etc/ssh/

cp sshd_config sshd_config.dist

vi sshd_config

PermitRootLogin without-password

AllowGroups root

apply,

/etc/rc.d/rc.sshd restart

Add a few aliases to the system-wide env,

cd /etc/

cp profile profile.dist

vi profile

source /etc/bashrc

vi bashrc

case "$-" in *i*)

alias ll='ls -alhF'

alias cp='cp -i'

alias mv='mv -i'

alias rm='rm -i'

;;

esac

apply,

source /etc/profile

Deploy your custom gnu screen configs e.g.,

cd /etc/

mv screenrc screenrc.dist

wget http://pbraun.nethence.com/configs/misc/screenrc

cd ~/

wget http://pbraun.nethence.com/configs/misc/.screenrc

Configure syslog,

cd /etc/

mv syslog.conf syslog.conf.dist

cat > syslog.conf <<EOF9

*.* -/var/log/messages

EOF9

make sure the root group can watch the logs and other users can't,

cd /var/log/

ls -l messages

#disable syslogd MARKs,

# cd /etc/rc.d/

# vi rc.syslog

#add -m0 to lines 9 and10,

#echo -n "/usr/sbin/syslogd -m0 "

#/usr/sbin/syslogd -m0

apply,

/etc/rc.d/rc.syslog restart

Enable the NTP daemon as client,

cd /etc/

cp ntp.conf ntp.conf.dist

vi ntp.conf

server ntp.obspm.fr

apply,

chmod +x /etc/rc.d/rc.ntpd

/etc/rc.d/rc.ntpd restart

ntpq -p

Eventually add that handy local startup symlink,

cd /etc/

ls -l rc.local

ln -s rc.d/rc.local

Generate a first file index,

updatedb

ls -l /etc/cron.daily/slocate

Additional configurations

Enable your daemons more selectively,

cd /etc/rc.d/

chmod -x *

chmod +x rc.4 rc.6 rc.K rc.M rc.S rc.keymap rc.local rc.sshd rc.syslog rc.sysvinit rc.inet1 rc.inet2 rc.udev

#chmod +x rc.acpid

#chmod +x rc.gpm

#chmod +x rc.netdevice -- no need with a custom kernel

#chmod +x rc.nfsd

#chmod +x rc.rpc

#chmod +x rc.samba

#chmod +x rc.hald

#chmod +x rc.messagebus

#chmod +x rc.wireless

note. rc.udev is needed for xend to launch properly

note. no need for rc.pcmcia on a server

note. no need for rc.alsa on a server

note. no need for rc.yp with local or ldap auth

note. no need for rc.inetd for now

note. and for custom shutdown scripts eventually,

#chmod +x rc.local_shutdown

check,

ls -alkF | grep *$

Disable the pango shit,

chmod -x /usr/bin/update-gtk-immodules

chmod -x /usr/bin/update-gdk-pixbuf-loaders

chmod -x /usr/bin/update-pango-querymodules

#removepkg gtk+2 pango

Building the ISO

To build an isolinux image (starting with Slackware 8.0 upwards, 7.1 doesn't have the isolinux/ folder), you'll need at least those folders,

isolinux/

kernels/

slackware/ (with the sets you want)

note. the kernels/ folder is needed by the installer.

then use mkisofs,

mkisofs -o ../slackware.iso \

-R -J -A "Slackware Install" \

-hide-rr-moved \

-v -d -N \

-no-emul-boot -boot-load-size 4 -boot-info-table \

-sort isolinux/iso.sort \

-b isolinux/isolinux.bin \

-c isolinux/isolinux.boot \

-V "SlackCD" .

Framebuffer modes

As boot time kernel argument e.g.,

vga=791

Here's the avalable modes,

640x480 800x600 1024x768 1280x1024

256 (8bit) 769 771 773 775

32000 (15bit) 784 787 790 793

65000 (16bit) 785 788 791 794

16.7 Mill.(24bit) 786 789 792 795

NFS server

Choose RW or RO,

cd /etc/

vi exports

/tftpboot *(rw,async,no_subtree_check,no_root_squash)

chmod 755 /etc/rc.d/rc.nfsd

chmod 755 /etc/rc.d/rc.rpc

/etc/rc.d/rc.nfsd start

/etc/rc.d/rc.rpc start

and to reload the conf after changes,

exportfs -a
