or set custom options.
The /etc/rc.serial is for serial port initialization
(e.g. locking the port characteristics, and so on.).
The /etc/rc.i386 is for Intel-specifics settings, such
as iBCS2 emulation or the PC system console configuration.
Starting with 2.1.0R, you can also have "local" startup files in a
directory specified in /etc/sysconfig (or
/etc/rc.conf ):
# Location of local startup files.
local_startup=/usr/local/etc/rc.local.d
Each file ending in If you want to ensure a certain execution order without changing all
the file names, you can use a scheme similar to the following with
digits prepended to each file name to insure the ordering:
10news.sh
15httpd.sh
20ssh.sh
It can be seen as ugly (or SysV :-)) but it provides a simple and
regular scheme for locally-added packages without resorting to
magical editing of /etc/rc.local . Many of the ports/packages
assume that /usr/local/etc/rc.d is a local startup directory.
How do I add a user easily?

How can I add my new hard disk to my FreeBSD system?
See the Disk Formatting Tutorial at
.
I have a new removable drive, how do I use it?
Whether it's a removable drive like a ZIP or an EZ drive (or
even a floppy, if you want to use it that way), or a new hard
disk, once it's installed and recognized by the system, and
you have your cartridge/floppy/whatever slotted in, things are
pretty much the same for all devices.
(this section is based on )
If it's a ZIP drive or a floppy , you've already got a DOS
filesystem on it, you can use a command like this:
mount -t msdos /dev/fd0c /floppy
if it's a floppy, or this:
mount -t msdos /dev/sd2s4 /zip
for a ZIP disk with the factory configuration.
For other disks, see how they're laid out using /stand/sysinstall .
The rest of the examples will be for a ZIP drive on sd2, the third
SCSI disk.
Unless it's a floppy, or a removable you plan on sharing with
other people, it's probably a better idea to stick a BSD file
system on it. You'll get long filename support, at least a 2X
improvement in performance, and a lot more stability. First, you
need to redo the DOS-level partitions/filesystems. You can either
use or /stand/sysinstall , or for a small
drive that you don't want to bother with multiple operating system
support on, just blow away the whole FAT partition table (slices)
and just use the BSD partitioning:
dd if=/dev/zero of=/dev/rsd2 count=2
disklabel -Brw sd2 auto
You can use disklabel or /stand/sysinstall to create multiple
BSD partitions. You'll certainly want to do this if you're adding
swap space on a fixed disk, but it's probably irrelevant on a
removable drive like a ZIP.
Finally, create a new file system, this one's on our ZIP drive
using the whole disk:
newfs /dev/rsd2c
and mount it:
mount /dev/sd2c /zip
and it's probably a good idea to add a line like this to
so you can just type "mount /zip" in the
future:
/dev/sd2c /zip ffs rw,noauto 0 0
How do I mount a secondary DOS partition?
The secondary DOS partitions are found after ALL the primary
partitions. For example, if you have an "E" partition as the
second DOS partition on the second SCSI drive, you need to create
the special files for "slice 5" in /dev, then mount /dev/sd1s5:
# cd /dev
# ./MAKEDEV sd1s5
# mount -t msdos /dev/sd1s5 /dos/e
Can I mount other foreign filesystems under FreeBSD?
for more information.
Any other information on this subject would be appreciated.
How can I use the NT loader to boot FreeBSD?
The general idea is that you copy the first sector of your
native root FreeBSD partition into a file in the DOS/NT
partition. Assuming you name that file something like
c:\bootsect.bsd (inspired by c:\bootsect.dos ),
you can then edit the c:\boot.ini file to come up with
something like this:
[boot loader]
timeout=30
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows NT"
C:\BOOTSECT.BSD="FreeBSD"
C:\="DOS"
This procedure assumes that DOS, NT, FreeBSD, or whatever
have been installed into their respective fdisk partitions on the
Mount a DOS-formatted floppy (if you've converted to NTFS) or the
FAT partition, under, say, /mnt .
dd if=/dev/rsd0a of=/mnt/bootsect.bsd bs=512 count=1
Reboot into DOS or NT. NTFS users copy the
attrib -s -r c:\boot.ini
Edit to add the appropriate entries from the example
attrib -r -s c:\boot.ini
If FreeBSD is booting from the MBR, restore it with the DOS

How do I boot FreeBSD and Linux from LILO?
If you have FreeBSD and Linux on the same disk, just follow
LILO's installation instructions for booting a non-Linux operating
system. Very briefly, these are:
Boot Linux, and add the following lines to
/etc/lilo.conf :
other=/dev/hda2
table=/dev/hda
label=FreeBSD
(the above assumes that your FreeBSD slice is known to Linux as
/dev/hda2 ; tailor to suit your setup). Then,
run lilo as root and you should be done.
If FreeBSD resides on another disk, you need to add
``loader=/boot/chain.b '' to the LILO entry.
For example:
other=/dev/sdb4
table=/dev/sdb
loader=/boot/chain.b
label=FreeBSD
In some cases you may need to specify the BIOS drive number
to the FreeBSD boot loader to successfully boot off the second disk.
For example, if your FreeBSD SCSI disk is probed by BIOS as BIOS
disk 1, at the FreeBSD boot loader prompt you need to specify:
Boot: 1:sd(0,a)/kernel
On FreeBSD 2.2.5 and later, you can configure
to automatically do this for you at boot time.
The is a good reference for
FreeBSD and Linux interoperability issues.
How do I boot FreeBSD and Linux using BootEasy?
Install LILO at the start of your Linux boot partition instead of
in the Master Boot Record. You can then boot LILO from BootEasy.
If you're running Windows-95 and Linux this is recommended anyway,
to make it simpler to get Linux booting again if you should need
to reinstall Windows95 (which is a Jealous Operating System, and
will bear no other Operating Systems in the Master Boot Record).
Will a ``dangerously dedicated'' disk endanger my health?
The installation procedure allows you to chose
two different methods in partitioning your harddisk(s). The default way
makes it compatible with other operating systems on the same machine,
by using fdisk table entries (called ``slices'' in FreeBSD),
with a FreeBSD slice that employs partitions of its own.
Optionally, one can chose to install a boot-selector to switch
between the possible operating systems on the disk(s).
Now, while this is certainly the common case for people
coming from a PC background, those people coming more from a
Unix background and who are going to setup a machine just to
run FreeBSD and only FreeBSD, are more used to the classic
Unix way where the operating system owns the entire disks,
from the very first sector through the end. A true fdisk
table isn't of any use in this case, the machine is running
FreeBSD 24 hours per day, 7 days per week, no other operating
system should ever be booted on it. So, if you select
``A)ll FreeBSD'' in sysinstall's fdisk editor, and answer the
next question with ``No'', you'll get this mode. Note that
this means the BSD bootstrap also forms the MBR for this drive,
so there's no space left for anything like a boot manager.
Don't ever try to install one, or you'll damage the BSD
bootstrap.
So why it is called ``dangerous''? A disk in this mode
doesn't contain what normal PC utilities would consider a
valid fdisk table. Depending on how well they have been
designed, they might complain at you once they are getting
in contact with such a disk, or even worse, they might
damage the BSD bootstrap without even asking or notifying
you. Some kind of operating system that is in rather
widespread use on PCs is known for this kind of
user-unfriendliness (of course, it does this in the name of
``user-friendliness''). At least one Award BIOS that is for
example used in HP Netservers (but not only there) is known
to ignore any harddisk that doesn't have what it believes to
be a valid fdisk table. When it comes to booting, it simply
ignores such a disk drive, advances to the floppy drive, and
barfs at you with just ``Read error''. Very impressive, eh?
They probably also call this ``user-friendly'', who knows?
The advantages of this mode are: FreeBSD owns the entire
disk, no need to waste several fictitious `tracks' for just
nothing but a 1980-aged simplistic partitioning model
enforcing some artificial and now rather nonsensical
constraints on how this partitioning needs to be done.
These constraints often lead to what might be the biggest
headaches for OS installations on PCs, geometry mismatch
hassles resulting out of two different, redundant ways how
to store the partitioning information in the fdisk table.
See the chapter about [. In ``dangerously dedicated'' mode, the
BSD bootstrap starts at sector 0, and this one is the only
sector that always translates into the same C/H/S values,
regardless of which `translation' your BIOS is using for
your disk. Thus, you can also swap disks between
systems/controllers that use a different translation scheme,
without risking that they won't boot anymore.
]To return a ``dangerously dedicated'' disk for normal PC
use, there are basically two options. The first is, you
write enough NULL bytes over the MBR to make any subsequent
installation believe this to be a blank disk. You can do
this for example with
dd if=/dev/zero of=/dev/rsd0 count=15
Alternatively, the undocumented DOS ``feature''
fdisk /mbr
will to install a new master boot record as well, thus clobbering the
BSD bootstrap.
How can I add more swap space?
The best way is to increase the size of your swap partition, or
take advantage of this convenient excuse to add another disk.
Adding swap onto a separate disk makes things faster than
simply adding swap onto the same disk. As an example, if you
are compiling source located on one disk, and the swap is on
another disk, this is much faster than both swap and compile
on the same disk. This is true for SCSI disks specifically.
IDE drives are not able to allow access to both drives on
the same channel at the same time (FreeBSD doesn't support mode 4, so
all IDE disk I/O is ``programmed''). I would still suggest putting
your swap on a separate drive however. The drives are so cheap,
it is not worth worrying about.
It is a really bad idea to locate your swap file over NFS
unless you are running in a very fast networking environment, with
a good server.
Here is an example for 64Mb vn-swap (/usr/swap0 , though
of course you can use any name that you want).
Make sure your kernel was built with the line
pseudo-device vn 1 #Vnode driver (turns a file into a device)
in your config-file. The GENERIC kernel already contains this.
- create a vn-device
cd /dev
sh ./MAKEDEV vn0
- create a swapfile (
/usr/swap0 )
dd if=/dev/zero of=/usr/swap0 bs=1024k count=64
- enable the swap file in
/etc/rc.conf
swapfile="/usr/swap0" # Set to name of swapfile if aux swapfile desired.
- reboot the machine
To enable the swap file immediately, type
vnconfig -ce /dev/vn0c /usr/swap0 swap

What's inappropriate about my ccd?
The symptom of this is:
# ccdconfig -C
ccdconfig: ioctl (CCDIOCSET): /dev/ccd0c: Inappropriate file type or format
#
This usually happens when you are trying to concatenate the
`c' partitions, which default to type `unused'. The ccd
driver requires the underlying partition type to be
FS_BSDFFS. Edit the disklabel of the disks you are trying
to concatenate and change the types of partitions to
`4.2BSD'.
Why can't I edit the disklabel on my ccd?
The symptom of this is:
# disklabel ccd0
(it prints something sensible here, so let's try to edit it)
# disklabel -e ccd0
(edit, save, quit)
disklabel: ioctl DIOCWDINFO: No disk label on disk;
use "disklabel -r" to install initial label
#
This is because the disklabel returned by ccd is actually a
`fake' one that is not really on the disk. You can solve
this problem by writing it back explicitly, as in:
# disklabel ccd0 > /tmp/disklabel.tmp
# disklabel -Rr ccd0 /tmp/disklabel.tmp
# disklabel -e ccd0
(this will work now)
Does FreeBSD support System V IPC primitives?
Yes, FreeBSD supports System V-style IPC. This includes shared
memory, messages and semaphores. You need to add the following
lines to your kernel config to enable them.
options SYSVSHM
options "SHMMAXPGS=64" # 256Kb of sharable memory
options SYSVSEM # enable for semaphores
options SYSVMSG # enable for messaging
Recompile and install.
How do I use sendmail for mail delivery with UUCP?
The sendmail configuration that ships with FreeBSD is
suited for sites that connect directly to the Internet.
Sites that wish to exchange their mail via UUCP must install
another sendmail configuration file.
Tweaking /etc/sendmail.cf manually is considered
something for purists. Sendmail version 8 comes with a
new approach of generating config files via some
preprocessing, where the actual hand-crafted configuration
is on a higher abstraction level. You should use the
configuration files under
/usr/src/usr.sbin/sendmail/cf
If you didn't install your system with full sources, the sendmail
config stuff has been broken out into a separate source distribution
tarball just for you. Assuming you've got your CD-ROM mounted, do:
cd /usr/src
tar -xvzf /cdrom/dists/src/ssmailcf.aa
Don't panic, this is only a few hundred kilobytes in size.
The file README in the cf directory can
serve as a basic introduction to m4 configuration.
For UUCP delivery, you are best advised to use the
mailertable feature. This constitutes a database
that sendmail can use to base its routing decision upon.
First, you have to create your .mc file. The
directory /usr/src/usr.sbin/sendmail/cf/cf is the
home of these files. Look around, there are already a few
examples. Assuming you have named your file foo.mc ,
all you need to do in order to convert it into a valid
sendmail.cf is:
cd /usr/src/usr.sbin/sendmail/cf/cf
make foo.cf
cp foo.cf /etc/sendmail.cf
A typical .mc file might look like:
include(`../m4/cf.m4')
VERSIONID(`Your version number')
OSTYPE(bsd4.4)
FEATURE(nodns)
FEATURE(nocanonify)
FEATURE(mailertable)
define(`UUCP_RELAY', your.uucp.relay)
define(`UUCP_MAX_SIZE', 200000)
MAILER(local)
MAILER(smtp)
MAILER(uucp)
Cw your.alias.host.name
Cw youruucpnodename.UUCP
The nodns and nocanonify features will
prevent any usage of the DNS during mail delivery. The
UUCP_RELAY clause is needed for bizarre reasons,
don't ask. Simply put an Internet hostname there that
is able to handle .UUCP pseudo-domain addresses; most likely,
you will enter the mail relay of your ISP there.
Once you've got this, you need this file called
/etc/mailertable . A typical example of this
gender again:
#
# makemap hash /etc/mailertable.db < /etc/mailertable
#
horus.interface-business.de uucp-dom:horus
.interface-business.de uucp-dom:if-bus
interface-business.de uucp-dom:if-bus
.heep.sax.de smtp8:%1
horus.UUCP uucp-dom:horus
if-bus.UUCP uucp-dom:if-bus
. uucp-dom:sax
As you can see, this is part of a real-life file. The first
three lines handle special cases where domain-addressed mail
should not be sent out to the default route, but instead to
some UUCP neighbor in order to ``shortcut'' the delivery
path. The next line handles mail to the local Ethernet
domain that can be delivered using SMTP. Finally, the UUCP
neighbors are mentioned in the .UUCP pseudo-domain notation,
to allow for a ``uucp-neighbor!recipient'' override of the
default rules. The last line is always a single dot, matching
everything else, with UUCP delivery to a UUCP neighbor that
serves as your universal mail gateway to the world. All of
the node names behind the uucp-dom: keyword must
be valid UUCP neighbors, as you can verify using the
command uuname .
As a reminder that this file needs to be converted into a
DBM database file before being usable, the command line to
accomplish this is best placed as a comment at the top of
the mailertable. You always have to execute this command
each time you change your mailertable.
Final hint: if you are uncertain whether some particular
mail routing would work, remember the -bt option to
sendmail. It starts sendmail in address test mode ;
simply enter ``0 '', followed by the address you wish to
test for the mail routing. The last line tells you the used
internal mail agent, the destination host this agent will be
called with, and the (possibly translated) address. Leave
this mode by typing Control-D.
j@uriah 191% sendmail -bt
ADDRESS TEST MODE (ruleset 3 NOT automatically invoked)
Enter
> 0 foo@interface-business.de
rewrite: ruleset 0 input: foo @ interface-business . de

How do I set up mail with a dialup connection to the 'net?

How do I reformat DOS text files to UNIX ones?
Simply use this perl command:
perl -i.bak -pe 's/\r\n/\n/g' file ...
file is the file(s) to process. The modification is done in-place,
with the original file stored with a .bak extension.
Alternatively you can use the command:
tr -d '\r' < dos-text-file > unix-file
dos-text-file is the file containing DOS text while
unix-file will contain the converted output. This can
be quite a bit faster than using perl.

How do I uninstall Kerberos?
To remove Kerberos from the system, reinstall the bin distribution
for the release you are running. If you have the CDROM, you can
mount the cd (we'll assume on /cdrom) and run
cd /cdrom/bin
./install.sh
How do I add pseudoterminals to the system?
If you have lots of telnet, ssh, X, or screen users, you'll probably run
out of pseudoterminals. Here's how to add more:
- Build and install a new kernel with the line
pseudo-device pty 256
in the configuration file.
- Run the command
# cd /dev
# ./MAKEDEV pty{1,2,3,4,5,6,7}
to make 256 device nodes for the new terminals.
- Edit
/etc/ttys and add lines for each of the 256
terminals. They should match the form of the existing entries, i.e. they look like
ttyqc none network
The order of the letter designations is tty[pqrsPQRS][0-9a-v] ,
using a regular expression.
- Reboot the system with the new kernel and you're ready to go.
