Fstab

Gutrus gutrus: /* Useful Examples */

The /etc/fstab file tells the system how and where to mount filesystems by default.

==Syntax==
The syntax of the file is this:

<table cellspacing="10">
<tr>
<td align="right">MAN PAGE-ese:</td>
<td align="center">FS_SPEC</td>
<td align="center">FS_FILE</td>
<td align="center">FS_VFSTYPE</td>
<td align="center">FS_MNTOPS</td>

<td align="center">FS_PASSNO</td>

<td align="center">/mnt/windows</td>
<td align="center">vfat</td>
<td align="center">defaults</td>
<td align="center">0</td>
<td align="center">1</td>
</tr>
</table>

==Field Descriptions==
FS_SPEC (DEVICE) - the device or remote filesystem to be mounted.

FS_FILE (MOUNT_POINT) - the mount point for the filesystem. NOTE: For swap partitions, this field should be specified as `none'. If the name of the mount point contains spaces these can be escaped as `\040'.

FS_VFSTYPE (FILESYSTEM)- the type of the filesystem. As of Slackware 10.2, the FILE_SYSTEM choices are:
:auto, adfs, affs, autofs, coda, cramfs, devpts, efs, ext2, ext3, hfs, hpfs, iso9660, jfs, minix, msdos, ncpfs, nfs, nfs4, ntfs, proc, qnx4, reiserfs, romfs, smbfs, sysv, tmpfs, udf, ufs, umsdos, vfat, xfs, xiafs and possibly others.
NOTE: for swap-able and portable devices (e.g. memory sticks and CDROMs), <code>auto</code> is the best choice because it allows the computer to determine the correct filesystem.

FS_MNTOPS (OPTION) - the (comma seperated) mount options. See the MOUNT command's MAN PAGE for the options because there are MANY!
The most commonly used options are: 
:noauto - do not mount this device/partition automatically on boot-up.
:ro - mount this device/partition READ-ONLY (e.g. CDROM).
:owner - Only allow the owner to mount and un-mount this device/partition.
:users - Allow any user to mount or unmount this device/partition.

FS_FREQ (DUMP) - used for these filesystems by the dump command to determine which filesystems need to be dumped. If the fifth field is not present, a value of zero is returned and dump will assume that the filesystem does not need to be dumped. For the most part, this should be "0" (zero).

FS_PASSNO (FSCK_ORDER) - used by the fsck program to determine the order in which filesystem checks are done at reboot time. The root filesystem should be specified with a fs_passno of 1, and other filesystems should have a fs_passno of 2. Filesystems within a drive will be checked sequentially, but filesystems on different drives will be checked at the same time to utilize parallelism available in the hardware. If the sixth field is not present or zero, a value of zero is returned and fsck will assume that the filesystem does not need to be checked.

==Benefits Of fstab Entries==
Once you have a device in the fstab, mounting become VERY easy. Instead of having to:
:<code>mount -t iso9660 /dev/hdb1 /mnt/cdrom</code>
every time you want to use the CDROM, you can just type:
:<code>mount /mnt/cdrom</code>
IF you have the entry in your fstab.

==Useful Examples==
CDROM/DVD: 
:/dev/sr0 /media/dvd auto noauto,ro,owner,users 0 0

[[USB Memory Stick]]: 
:/dev/sda1 /mnt/memstick auto noauto,owner,users 0 0 
(make sure to <code>mkdir /mnt/memstick</code> after changing your /etc/fstab).

[[External USB Drive / NTFS partition]]
:/dev/sdd1 /media/1T ntfs-3g auto 0 0
(/dev/sdd1 is your external USB hard drive and /media/1T is destination folder)

Note: For changing who can access the filesystem on NON-Native linux formats see [[Permissions and Umasks]] and [[Windows Partitions]]

Gutrus gutrus:

== Hostname ==

You can change a Slackware box's <code>hostname</code> by two methods:

1) Edit <code>/etc/HOSTNAME</code>

2) Use the hostname command-

:On any running Linux system you can change its hostname with the command ‘hostname‘.

::'''<code>hostname</code>''' without any parameter it will output the current hostname of the system.

::'''<code>hostname –f</code>''' will output the fully qualified domain name (or FQDN) of the system.

::'''<code>hostname NEW_NAME</code>''' will set the hostname of the system to NEW_NAME. This is active right away and will remain so until the system is rebooted (because at system boot it sets this from some particular file configuration - see bellow how to set this permanently). You will most probably need to exit the current shell in order to see the change in your shell prompt.

PPPoE

Gutrus gutrus — Wed, 30 Jan 2013 10:05:31 GMT

Gutrus gutrus: /* Connecting With PPPoE */

[[Category:Tutorials]]

== Setting Up PPPoE ==

As root, run '''pppoe-setup'''. Answer the questions.

'''GOTCHA:''' on the last question, answer ''1 STAND ALONE''.

== Connecting With PPPoE ==

As root, run '''pppoe-start'''.

You should now be connected.

PROBLEM: It reports connected but, I can't get to the internet.

FIX: It's probably screwed up your routing table.
::route del default
::route add default dev ppp0
Your connection should be working now.

To make this process automatic at bootup, add the following lines at the end of file /etc/rc.d/rc.local:

::pppoe-start
::route del default
::route add default dev ppp0

and then reboot...
