how the usb/dvd mounts automatically ?

[needee]

OS: SLES / SLED 10

whenever I insert usb drive, or a dvd into the dvd-drive, suse automatically mounts the usb/cd/dvd ... HOW ? I havent configure the automount/autofs, neither i found any config in /etc/auto.master.

So my question is how the usb drives, and cd/dvd, automatically mounts in suse 10 ?
which service is responsible ?
and how can I check the configs ?

PLz help
Thanks n Regards

Automatic mounts are taken care by automount daemon.

Check your /etc/fstab, /etc/auto.master, and /etc/misc files for more info.

/etc/auto.master is default, i.e all lines are commented
cat /etc/auto.master
#
# $Id: auto.master,v 1.4 2005/01/04 14:36:54 raven Exp $
#
# Sample auto.master file
# This is an automounter map and it has the following format
# key [ -mount-options-separated-by-comma ] location
# For details of the format look at autofs(5).
#/misc /etc/auto.misc --timeout=60
#/smb /etc/auto.smb
#/misc /etc/auto.misc
#/net /etc/auto.net

/etc/auto.misc is default, i.e all lines are commented, except the following

cd -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom

Is the above line is used to mount the cd/dvd automatically ? even though there is no entry in auto.master(normally we have to add a line in auto.master also) ... will the above line will work ? ok... if the above line is sufficient to mount the cd/dvd automatically, then how/why the usb drives mounts automatically ?

Thanks n Regards

Yes, u r right. This line

cd -fstype=iso9660,ro,nosuid,nodev :/dev/cdrom

mounts cd/dvd automatically. But I am not sure about USB. Usually, it would be in /etc/fstab for mounting USBs.

Is thr any hotplug - detecting daemons to do this???

This is what does it in /etc/fstab:

usbfs /proc/bus/usb usbfs noauto 0 0

Thanks Dear cyberinstru and Pumalite for reply/help

>usbfs /proc/bus/usb usbfs noauto 0 0
see the option "noauto"... i.e the filesystem/device will not mount automatically ... but sles/sled 10 mounts usb automatically ... how ?

[cyberinstru]

hey, after mounting USB, check the output of /etc/mtab.

We shall infer from the mount point used.

[needee]

hi cyberinstru
# cat /etc/mtab
.
.
.
/dev/sdb1 /media/KINGSTON vfat rw,noexec,nosuid,nodev,flush,shortname=winnt,utf8, uid=0 0 0
