auto direct

auto direct

[EAGOMEZC]

Hi, 

i´ll need to setup direct maps in a linux box using a nis server on Solaris 8. 
This option is not supported in autofs 4.

I don´t know why is not supported, why ? is not implemented, or are there any security tip ? 

Are there another way to mount direct maps ?

Thanks

Your not entirely correct.

Maybe you should investigate a bit before making these assumptions.

What Ian means is look at
     /usr/share/doc/autofs-4.x.y/README.direct.

You may also find some threads on this in the autofs mailing list archives.

well - to be helpful - direct mounts are supported if you have
a non-root mount point (a mount point other than '/')

/etc/auto.direct (works):

/mount/auto  -options server:/path/to/mount/point

but

/etc/auto.direct (won't work):

/mountauto  -options server:/path/to/mount/point

That's right and it is still a problem.

It is a limitation of the current implementation.

Not until the direct mount rework is done.
First I've spent a long time deciding on how best to implement it.
Second, the original method was used, largely due to the restricted number 
of anonymous mounts available in 2.4.
Third, the kernel module changes needed are a bit tricky. They'll need 
significant testing when the work is done, as will the userspace code.
Fourth, I've had a more or less constant stream of bug fix and basic 
functionality work needed with the package. It's way hard implement 
against a moving target.

Perhaps. What do you have in mind?

auto direct

[Bazan, Wojciech]

[-- Attachment #1.1: Type: text/plain, Size: 2039 bytes --]

Hello,

 

Are there any known issues with auto direct automounts on RHEL.... (see
details below)

 

# uname -r

2.6.9-78.0.8.ELsmp

# more /etc/redhat-release 

Red Hat Enterprise Linux AS release 4 (Nahant Update 7)

# rpm -qi autofs-4.1.3-234

Name        : autofs                       Relocations: (not
relocatable)

Version     : 4.1.3                             Vendor: Red Hat, Inc.

Release     : 234                           Build Date: Thu 19 Jun 2008
05:18:46 PM BST

Install Date: Tue 16 Dec 2008 06:08:11 PM GMT      Build Host:
hs20-bc1-5.build.redhat.com

Group       : System Environment/Daemons    Source RPM:
autofs-4.1.3-234.src.rpm

Size        : 960684                           License: GPL

Signature   : DSA/SHA1, Tue 01 Jul 2008 02:32:36 PM BST, Key ID
219180cddb42a60e

Packager    : Red Hat, Inc. <http://bugzilla.redhat.com/bugzilla>

Summary     : A tool for automatically mounting and unmounting
filesystems.

Description :

Autofs controls the operation of the automount daemons. The automount

daemons automatically mount filesystems when you use them and

unmount them after a period of inactivity. Filesystems can include

network filesystems, CD-ROMs, floppies, and other media.

 

Install this package if you want a program for automatically mounting

and unmounting filesystems. If your Red Hat Linux machine is on a

network, you should install autofs.

 

 

Although the configuration seems to be perfectly fine:

 

# more /etc/auto.master

...

/misc   /etc/auto.misc

/net    /etc/auto.net

/-      /etc/auto.direct

 

# more /etc/auto.direct 

...

/PKGrep <host>:/export/PKGrep

 

It does not want to start autofs saying:

 

automount[9521]: cache_ghost: entry in file:/etc/auto.direct not valid
map format, key /PKGrep

 

 

Auto direct work however if we do not use the dir directly under root.

 

Any ideas?

 

Many thanks,

Wojtek

That's right, the pseudo direct mount support in version 4 has several
limitations and this is one.
