NIS Related Issue

I'm new to Linux, I want to master all of the lovely little details about what makes Linux tick, and how it ticks. I would love to know any suggestions of where I should start. I want to know how anything, the hardware, software, and firmware works. I am wanting to get into computer science, I'm very motivated and am willing to put in the time to learn and master Linux. I figure that Linux is a good of a place to start as any, seeing how there is a lot of source code to study and open source software to play around with.

Hi All

I have been racking my brains for the past 15 hours or so trying to know why my AD users can't actually login to the share which i have assigned.

This is my smb.conf below:

Quote:
[global]
workgroup = EXAMPLE
security = ads
realm = EXAMPLE.GROUP
domain master = no
local master = no
preferred master = no
printcap name = /etc/printcap
load printers = no
idmap backend = tdb
idmap uid = 10000-99999
idmap gid = 10000-99999
idmap config EXAMPLE:backend = rid
idmap config EXAMPLE:range = 10000-9999
winbind enum users = yes
winbind enum groups = yes
winbind use default domain = yes
winbind nested groups = yes
winbind refresh tickets = yes
winbind offline logon = true
template homedir = /home/%D/%U
template shell = /bin/false
client use spnego = yes
client ntlmv2 auth = yes
encrypt passwords = yes
restrict anonymous = 2
log file = /var/log/samba/samba.log
log level = 2
valid users = any
[Research]
comment = Research
path = /sharing/research
valid users = EXAMPLE\user1
force group = "domain users"
writable = yes
read only = no
force create mode = 0660
create mask = 0777
directory mask = 0777
force directory mode = 0770
access based share enum = yes
hide unreadable = yes
[Admin]
comment = Admin Area
path = /var/www/html/cmsmadesimple
browseable = yes
writable = yes
read only = no
inherit acls = yes
inherit permissions = yes
create mask = 700
directory mask = 700
valid users = user1

When i do wbinfo -u or wbinfo -g i can see the usernames and groups in my AD.

Also when i do : id username it actually gives me the information for that user in my domain.

I have done net ads login -U and joined the domain.

I have set the pam auth modifications and the krb5 and nsswitch.conf files.

So i do not get why i can't have the user i have assigned to that share access it?

I can only imagine i have something wrong in my smb.conf?

Please any helps would be appreciated.

Thanks

For one user I generated a gpg2 key-pair. I exported these to ascii-armour text files as master.asc and pub.asc. Then took only the pub.asc onto the keyring of a second user on the same partition. I "signed" a simple text file (say trial.txt) with the master key and also transferred it to the home directory of the second user. The pub key on the second user's keyring could verify the signature on the signed text file (trial.txt.gpg) but could not decrypt it. Also, a file encrypted by the second user with the pubkey could be decrypted by the masterkey. Each key therefore has, embedded in its structure, information about child/parent keys. Can anyone thrown light on the actual method of incorporation of this mutual recognition in the key structures? Note:The same kind of recognition happens with sub-keys derived from the Master-key. Can't find any literature which details. Help pl.

In our environment i have to ssh to each an every servers
ssh <hostname> then which prompts for password for every login
i have to create a user name on 30 severs manually it takes much time so need a script to do this task i have googled and found some for loop scripts but it did not fullfill the requirement.
First i have to check whether the users exists and not and later add the user or reset the password for user using script

Hi, I downloaded an ISO linux file for my Vmware it was with a read me file that show the login details into the OS. Now have finished the installation of the ISO on my Vmware but the problem I have is it not accepting the login details that came with the ISO I download.
this was the login that came with the ISO:

standard user:
username: user
password: password

administrative user:
username: root
password: password
It not accepting any of it I want to know if I did something wrong or there is master login deatils I can use to get to the desktop.
Am a real newbie this is my first time of dealing with Linux your answers will be appreciated a lot. Thanks.

Noticed recently that my first SSH attempt (using putty) to a Red Hat server always fail. Must leave the failed session on, then the second SSH attempt will succeed. If I close the failed ssh session, the second attempt will also fail as well.

This issue only cropped up about two weeks ago and it also happens to other users for this RHEL server only. I am using putty(release 0.64) but other users are connecting to it via command line SSH in their Linux desktop. Not aware of any changes done to this RHEL server recently.

Any suggestions on where should I start looking into?

Hello, I'm sort of a novice Linux user and was running into an issue with user migration. I'm trying to migrate users and groups from a RHEL 5.11 install to a CentOS 6.6 install, both systems are 64 bit. Initially I tried to do an rsync of the passwd, shadow, group and gshadow files with no luck. When trying to login with an existing account on the new server I get access denied. I tried to change the password on the new server, but even then it doesn't seem to change the password and I still get access denied. I then tried to tar up the four above files and then extracted them on the new server, but the same issue existed. I also created a new account on the old server, copied all the necessary files over to the new server and still have the same issues. Any ideas what I may be doing wrong or what I can try next? This is getting frustrating!

Thanks!

Hi All,

Please help me. I'm following the book - ' DNS and BIND, 5th Ed By Paul Albitz, Cricket Liu '. This RNDC is driving me crazy. I spent all day trying to configure rndc. Tried every possible combination in config files, but I just cant control remote server. Tried many tutorials from google, nothing helped. LQ is my last hope.

So, my story goes like this...

MASTER BIND SERVER:
Host: toystory.movie.edu
IP: 10.249.249.3/24
OS: CentOS 7.1

SLAVE BIND SERVER:
Host: wormhole.movie.edu
IP: 10.249.249.2/24
OS: CentOS 6.6

MASTER SERVER (toystory) CONFIGURATION FILES:
Code:

[root@toystory ~]# cat /etc/rndc.conf
key "toystory-key" {
	algorithm hmac-md5;
	secret "K9qBsQwusP6430cykS2AeA==";
};
options {
	default-key "toystory-key";
	default-server 127.0.0.1;
	default-port 953;
};

[root@toystory ~]# cat /etc/named.conf
key "toystory-key" {
	algorithm hmac-md5;
	secret "K9qBsQwusP6430cykS2AeA==";
};
controls {
	inet 127.0.0.1 port 953
		allow { 127.0.0.1; } keys { "toystory-key"; };
};
key "wormhole-key" {
	algorithm hmac-md5;
	secret "7PvoY3oysQz8DyASiUTlNA==";
};
controls {
	inet 10.249.249.3 port 953
		allow { 10.249.249.2; } keys { "wormhole-key"; };
};

SLAVE SERVER (wormhole) CONFIGURATION FILES:

What I'm doing wrong? Please Help!!!

Thanks

hi guys,

busy doing a small project with a centos7 server and virtualbox.
currently i have a login to the physical server called sninja

i have three partitions created for each of my virtual machines
sninja owns the directories for each vm...and root is the primary group...now lets say i wanted to have other users perform functions on my vm's ..ssh in,rsync data into the vm etc...

whats the best way to address security and user accounts etc?

what i was thinking:

create a group called Myusers1,then assign the users to that group and then make the group the primary group of the accessed directories etc

is this the right way to go about it? any ideas or help really appreciated...
