View 2 Replies View RelatedI am familiar with windows 2008 cluster servers, and I just started testing with centos cluster. I am creating a simple 2-node cluster, for a simple ping test.
Node 1: 10.0.0.1
Node 2: 10.0.0.1
Virtual ip: 10.0.0.10
So far, I can ping a virtual ip, and manually relocate it between the nodes, but I didn't figure out, how to do this automatically. So this is my question: How can I setup the cluster, to it automatically failover the a service to another node case one node fails?
I have a Node mounted from my Appserver (Solaris) to DBserver (Solaris), the reason why I Mount is that My Oracle writes file using UTIL_File in Dbserver only, so now I done the Mount and I can create file using VI in the Mounted point. But My UTIL_file is not able to create a file, the reason might be that Oracle writes only as ORA user and my Appserver has no such user, for that I have given the permission 777 for that particular folder, but no use, so I wonder do I need additional permission for this.

After each bootup, I need to run the following on the master machine:
Code:
drbdadm -- --overwrite-data-of-peer primary all
Do we need to specify which machine should be the primary node every time? Is there any method to make the machine "know" it's itself the primary node?
I have created a simple menu driven script for our Operations to take care of the basic monitoring and managing of our production application from the back-end. Now, the script when tested in UAT environment was fine, but when deployed to production it kind of behaved oddly.hen the Operator chooses an option from the menu he is given the output and at the end is prompted to return to the main menu by using ctrl+c. In production, this return does not occur for some strange reason and the program just sits there.The session becomes unresponsive after that and I'm forced to terminated it by closing the PuTTY.I tried enabling the debug mode too (set -x) and still was not able to find any useful hints/trails as to why.

View 1 Replies View RelatedI run a compute cluster with only a few users. Occasionally a user will accidently run a job on the master node that runs out RAM/swaps then hanges up for a while.In /etc/security/limits.conf I have set memlock to 7.5GB (master has 8GB RAM) and maybe that is what lets the machine come back rather than hanging completely? Is this the right setting to physocally limit a single user from asking for more RAM than the system has and bringing down the system? Should I set this to 2GB or so or is there something else I can do??

I've set up password-less login for user1 on a Ubuntu machine to login automatically into a Fedora box using the publickey authentication method. Everything is working smoothly. Now, there is a user2 on Fedora but he does not have an account on Ubuntu.
I tried to login as user2 from Ubuntu to but got the following error :
Code:
Predictably neither scp or sftp work either. I have several questions as a result.
1.Is the SSH server rejecting user2 login because I am inadvertently using user1 keys (as I am logged in as user1) ?
2. Do I need to have a user2 account on Ubuntu and public/private key authentication setup with Fedora for user2 to be able to login ?
3. Is there a method I can use to password login as user2 from Ubuntu to Fedora (even though there is no user2 account on Ubuntu) AND still keep password-less login for user1 or do I have to have password-less login for both ?
At present the only way to access the user2 account from Ubuntu is to SSH using the user1 account and then su to user2.
I've set up smbd 3.4.7 on 10.04x64 LTS server. I've set up a couple shares and I'm having problems blocking access to certain directories using native file permissions. There is one directory that has folders for each sales rep to store their current list of quoted clients, I only want sales people to be able to browse the directories owned by themselves. Everything seems to be set up correctly in terms of user groups and permissions on the filesystem.
Below is marina, a sales rep, and brian, a super user of sorts.
id marina:
Code:
uid=1011(marina) gid=1006(office) groups=1006(office),1005(sales)
id nick:
Code:
uid=1000(brian) gid=1006(office) groups=1006(office),118(admin),1001(full),1002(processing),1003(management),1004(it),1005(sales)
Below is the directory with all the sales reps folders.
ls -la:
Code:
total 60
drwxrwxr-x 15 root it 4096 2011-02-10 20:06 .
drwxr-x--- 9 root office 4096 2010-11-19 12:40 ..

drwxrwx--- 4 mike full 4096 2011-02-01 12:42 Mike
With this setup marina only be able to browse her folder, but she can browse all folders and has full write access to all folders. This leads me to believe something is up with the smbd.conf file, which is below.
Code:
[global]
workgroup = COMTREAD
null passwords = no
server string = Root Server
dns proxy = no
log file = /var/log/samba/log.%m
max log size = 1000
syslog = 0 .....
In this case the valid users directive would not work cause I am not making a share for each user. I had this on other shares like the db2 share. My windows box lagged heavily when I tried to access that share with an invalid user. How to deny users the ability to modify permissions I would also like to do that.
I am using Fedora 14 64-bit and after login through a user other than root when I try to open any folder on other partitions I get the message that I don't have permission to access such and such folders.

I want to prevent all users from executing executable files created by self , from its home directory .

View 1 Replies View RelatedI got myself curious on the possibility to change user's permission to any command, or at least giving other users some command line "power".
It all started a few days ago, when another user here, had a problem so that the computer wasn't answering.
So, after waiting a while, chose to hit the Reset button and start the computer again.
Considering this situation, I thought myself that it would have been better to restart the computer, through command line, on any terminal (F1-F6). Anyway, this user is no administrator, thus wouldn't have permission to use the code...
So, is it possible to let other users to use such commands, in order to safe rebooting the system, without logging as root?
I have setup a NFS server and this the content of /etc/exports at the server with IP A.B.C.D1 is:/home/shared A.B.C.D2(rw,no_root_squash)Problem is, only the root at A.B.C.D1 and A.B.C.D2 can write to that folder.
View 9 Replies View RelatedThe desktop computer of my two children has a total of three users:
1) The superuser (me)
2) The user 1001 (my elder son)
3) The user 1002 (my younger son)
Both users 1001 and 1002 can not access their files system, and also they can not save any attachments from incoming mails.
What I tried so far:
I accessed the file manager as superuser, and went: >Root>Home. Here I right-clicked on the folder User 1001, selected properties, selected the tab 'permissions' and allowed this user to read and write into this folder. I also checked the checkbox �extend this permission to all subfolders and its contents.
The problem is, when I reboot, everything is 'forgotten' and I am at quadrant zero again.
Eventually I should state that part of the folders are from a backup drive, because the hard disk had to be replaced so, once I re-installed the OS on the new hard drive, I copied the folders from the backup drive into the home folder.
One last question:
Is there a good tutorial about permissions?

I'm a refugee from WindowsXP, running Fedora 14 with three user accountsMy problem is that I need the primary user (userd 500) to be able to have full access all other users' files in their home directories so that user can copy, move, delete, etc.I tried making that user a member of the other users' groups - but I still get the 'not got permission' error when I try to access their home directories
View 8 Replies View RelatedI'm having trouble breaking down permissions in linux. Here's the scenario. I have two users: UserA & UserB with each having to ownership and access to directories myDirA and myDirB respectively.
UserA --> /source/myDirA
UserB --> /source/myDirB
I need to set the permissions so that userA can access myDirA and myDirB. There are other users and directories but they should not be able to view outside of their own directories (which is the way it is now). I don't have groups set up for them and I'd rather not change anything else but just the permissions.
rwxr_x_r_x UserA
rwxr_x_r_x UserB
They're read/write/exec permissions are identical.
I installed proftpd on my Ubuntu 10.10 install. I also run multiple websites that I want to allow ftp access to for 2 different users. The websites are located in /home/www/. This is where the guide I was following told me to put them. I also don't have a user named www.How can I give write permission to upload, delete, and edit all the files in /home/www/ for multiple users? They can connect to the ftp server and see the file, just not change them.
