I am trying to install my debian again. In this time I want to encrypt it using LVM and later LUks. How I do that? I am in installation process. And I want to create a Group LVM and later partition the container.
View 12 RepliesSo i am at the stage of about to install the basic system and am using a derivation of the package management provided by Matthias S. Benkmann. To this end I am using his useradd and groupadd scripts to update the files:
/etc/passwd
/etc/group
My issue is that when I run the commands(created as part of temporary system when installing coreutils):
Code:
/tools/bin/su linux
#then as user
/tools/bin/groups
(here linux is the name of the user) This only returns the user being in the group named after user but not the additional group of 'install' Also, prior to logging in as user, if I use this command as root:
Code:
/tools/bin/groups linux
linux install This then returns that the user is in the correct groups. Lines from relevant files look like:
Code:
#/etc/passwd
linux:x:10000:10000::/usr/src/build:/bin/bash
#/etc/group
[code].....
We are using OES 10.00 and would like ot print list of all users in the container.

I already know of a work around to fix this problem, but I guess my question is why is this not working as expected? I am using a Windows Server 2008 R2 Active Directory for authentication.
I have run auth-client-config for the ldap profile and pam-auth-update. When running getent passwd, I get a list of both the local users and the users in the active directory (with populated information in the Unix schema extension). When running getent group I get a list of both the local groups and the groups in the active directory (with populated information in the Unix schema extension).
Interestingly enough, though, when I run su DOMAINUSER, after the prompt for the password I get an authentication error. In /var/log/auth.log I can see an entry with pam_ldap: missing "host" in file "/etc/ldap.conf". The SRV records in the DNS servers resolve correctly. I've checked this with nslookup and I have seen the records within my zone file. Obviously if the ldap.conf file is working with getent and the ldap server is resolving from the SRV records, it is working fine.
The interesting part is that the Windows Server 2008 R2 AD machine shows in the event viewer that there was a successful authentication, yet the Ubuntu box says no. When I add the host within the ldap.conf file, everything works...getent and the actual authentication, either initial login or su.

I am currently trying to set up a Samba domain server. In the Samba-HOWTO-Collection I found an
example file.(Point 3.3.3.1) In the explanations of the example below, the author says I need to map UNIX Groups to NT Groups. He writes a shell-script of how one could do it, but when I copy it and then execute it, I get the error:
Bad option: rid=512
Bad option: rid=513
Bad option: rid=514
The other groups do get mapped, just the Domain Admins, Domain Users and Domain Guests dont. This is the shell from the HOWTO:
#!/bin/bash
#### Shell-Skript f ̈r sp ̈tere Verwendung aufbewahren
net groupmap modify ntgroup="Domain Admins" unixgroup=ntadmins rid=512
net groupmap modify ntgroup="Domain Users" unixgroup=users rid=513

How much of CPU should Firefox plugin continer be using? and what about Firefox bin? What are reasonable figures?
I've been monitoring them and seems to me at times they are running high, 40,50% even higher at times though then it drops back.
When I use firefox, I accumulate multiple plugin-container processes, typically one of them sits around hanging onto well over 200 MB of RAM. I think this happens when I watch flash videos. Does simply having a flash app on a web page cause a plugin-container process to be created? Will they ever go away without my explicitly killing them or closing firefox? If they stay around, do they ever free any RAM?

When i use the STL container alone it works fine, but when i include it into a C struct i have segmentation faults errors. I know that it is not a good idea to mix C and C++. Considering this code:
Code:

I'm using my Linux (SLES 10) server as a File Server at this point. I need to set File Permissions to nested folders differently to different groups. For example:
homesharedengineering* should be read only for groupA
homesharedengineeringadmin should be read & write for groupB Plus read only for groupA
homesharedengineeringautocad should be read & write for groupC Plus read only for groupA
I've been using Webmin and Putty to set permissions but Putty only allows me the Default Group, it won't allow me to set several groups on the same directory. Webmin seems to allow me to add multiple groups (Webmin --> Others --> File Manager --> Info & ACL tab will provide extended abilities) but when I add multiple groups, they don't seem to take effect? I'm wondering if my setup at the 'Share' level or at the hierarchy of my folder structure (unix based) needs to be set specifically?
So I know that Mac OSX post-production and Linux post-production are very different things. I'm hoping to give editing on Linux with Cinelerra a try and I'm wondering, what in FFMpeg's array of codec and container support is widely understood to be the best combination for editing video. I'm looking for the most lossless option so H.264 won't do. Is there a good Apple Intermediate Codec or Apple Pro Res equivalent? Is AVCHD the answer?

I am in need of a rather complicated permissions scheme for particular directory. I have a directory /data I want the group developers to have read and execute access to this directory. Then, I want the group research to have read, execute, and WRITE permission for this directory. Now, I have a second directory /code which developers and research have full access to. And I have a third group, operations I want operations to be able to read /data but not be able to read /code Is this permissions scheme possible in linux?

View 2 Replies View RelatedI'm new to LVM. I use Red Hat and CentOS 5. I'm setting up a database server and I want to setup the local drives for performance. My plan is to have three storage locations, 1st for Linux, 2nd for the application, and 3rd for the data files. Each location will be appropriately redundant. The OS and application drives will be local. Because my goal is to dedicate one spindle for the OS and another for the application, is there a best practice that would say I should create two LVM volume groups.
Each with one logical volume associated with one of the physical partitions or one LVM volume group with two logical volumes each associated with one of the physical partitions? I've read that a physical disk can only belong to one volume group. So if I want to add 70GB to both logical volumes, I could add a single 140GB drive to a single volume group and then add half to each logical volume. If I have two volume groups, I would need to add two additional disks. I may be missing an obvious consideration or be missing a basic concept of LVM.

View 2 Replies View RelatedI am building a livecd, the live user created at boot time is a member of the audio group set in /etc/group.

In /etc/default/useradd I can set only one group.
View 4 Replies View RelatedI've created a set of users using the newusers command. Unfortunatelly ive messed up and added all users to the 1000 group as primary group instead of giving the group argument as null what would add them to a new group. To make things clear:
The entries should be
user:password:::User Name:/home/user:/bin/bash
but I did
user:password::1000:User Name:/home/user:/bin/bash
I need to create the missing groups. A simple fix could be do a for loop creating a group with the name of each user in my file and then adding the users to it. Are there any dangers of doing it? What impact could this change have? Are there any safer ways?
A combination of the following commands:
Quote:
Add users to a group with the gpasswd command:
# gpasswd -a [user] [group]
To delete existing groups:
# groupdel [group]
To remove users from a group:
# gpasswd -d [user] [group]
If the user is currently logged in, he/she must log out and in again for the change to have effect.
Quote:
for i in (names)
do groupadd $i
gpasswd -a $i $i
Assuming I've created all users in group 1000 I could remove them from it with
Quote:
# gpasswd -d [user] [group]
I am a member of five groups within our network environment, but sometime, one of our systems can only find the primary group I belong to resulting in, that I cannot use the tools I have put behind a specific group. Sometimes it gives:
Code:
$ groups
meten1
instead of
Code:
$ groups
meten1 agilib cictest verigy tcntest
I think it has to do with the portmapper, since it is dead everytime it occurs.
Code:
$ /sbin/service portmap status
portmap dead but subsys locked
I checked the NIS settings and they are equal to the systems, on which I do not see this issue.
i have 5 groups, i want to set 3 of them to have full permissions to a folder and set 2 others with read only to same folder, please help me to solve this problem. in other words i want to set this 5 groups diffrent permissions to a folder.

View 1 Replies View Relatedmy current plan is to create a truecrypt container with the whirlpool hash. This container will be located on a hdd that is not where my OS will be located (so a separate physical sata drive).My concern is when this container is accessed, that some of the password information could be stored in my swap partition (which is on the main drive where the OS "/" is located)
I would like to have a script or command I could run that after I unmount those drives (or just halt the system) that my swap (and ram too if possible) could be wiped (or like overwritten with the shred command). Also, am I going about this the right way, or should I just use truecrypts FDE on the entire drive? In addition, when Ubuntu does it's default install, does it create a swap file in addition to a swap partition? If it does, would that be another vulnerability? If it is, how do I prevent this from happening?
I welcome any input you have on this. I am aware that once the drive is mounted, it is vulnerable, but I want the data to be secure as possible once my computer is turned off. Also, I have read that there are ram exploits where it holds your passwords for up to a few minutes after you turn the machine off, does anyone know how long that it and is there a way to clear it, or will only time let it fade?
I am using DVD::rip to convert some instructional DVD's to .avi (xvid + mp3). I have never used this app before but its seems fairly straight forward and easy to use. I am able to convert 1 title from the DVD to 1 avi file. One DVD however has 19 titles which vary from 3-5 minutes in length. My question is, can I convert all or at least some titles to a single .avi file and if so how?
