Typical usage of programs like sed, gzip, … can be found in linux-unix section.
smartctl -A /dev/ad0 | grep Load
If this value is increased every few minutes, you have the problem ! And your hard disk could be break only in few months ! Each time parking occures, you can hear a “click” from your disk.
Normally, you must have only few cycles per day!
There is a solution, set the hard disk to most performance (and most energy consumption) with the utility: ataidle (I installed it with the ports /usr/ports/sysutils/ataidle)
Then you can type: ataidle -P 254 /dev/ad0 and it will save your hard drive :evil:
atactl /dev/wdXc apmset 253
If you want to do it at boot, add to your rc.conf
ataidle_enable=“YES”
ataidle_device=“ad0”
ataidle_ad0=“-P 254”
fdisk -i sdX disklabel -e sdX newfs sdXZ mount /dev/sdXZ /mnt
Display current VPN Tunnels:
ipsecctl -sa
Start daemon and load configs:
isakmpd -K ipsecctl -f /etc/ipsec.conf
pfctl -t %TABLENAME% -T show
pfctl -s all
tcpdump -n -e -ttt -r /var/log/pflog
tcpdump -n -e -ttt -i pflog0
boot> boot -s
2. Now run fsck on all partitions, to make sure things are okay for changes
Enter pathname of shell or RETURN for sh: <press enter> # fsck -p
3. Mount all filesystems # mount -a
export the TERM environmental variable only if you need to edit files: # export TERM=vt220
4. Reset root's password and then reboot
# passwd Changing local password for root. New password: ILikeMonkeys Retype new password: ILikeMonkeys # shutdown -r now
kill -HUP `cat /var/run/%DAEMON%.pid`
lsof -i
fstat | grep .%PORT%
To mount SMB/CIFS shares, use sharity-light (windowsserver must be added to /etc/hosts).
pkg_add sharity-light
shlight //windowsserver/backup /mnt/backup -U windows_user -P someuglypassword
unshlight -a [node]
To poweroff after shutdwon:
halt -p
or
powerdown=YES
in /etc/rc.shutdown file

Copy /etc/X11/xinit/xinitrc to ~/.xinitrc and add or remove programs to launch in fvwm.
FVWM is the default Window Manager. The configuration file is .fvwmrc in /usr/X11R6/lib/X11/fvwm/ or in the user's home dir. This is the configuration to add some applications to the menu.
''AddToMenu RootMenu "Root Menu" Title + "XTerm%mini.xterm.xpm%" Exec exec xterm + "FireFox" Exec exec firefox + "Thunderbird" Exec exec thunderbird + "Nedit" Exec exec nedit''
To set a different background:

If you have problems on screen resolution, change to this the same section of xorg config file:
Section "Monitor"
Identifier "Configured Monitor"
HorizSync 28-73
EndSection
You can configure and generate the xorg config file using the command “X -configure” and try the configuration using “X -config ./xorg.conf.new”.
The correct file need to be copied to /etc/X11/xorg.conf.
Modify files in /usr/share/sendmail/cf/ (/usr/share/sendmail/cf/openbsd-localhost.mc)
Build cf file:

Copy result to the /etc/mail directory
Restart the sendmail daemon
$ . ~/.bashrc
