yum setup on RHEL 6 and samba installation

Here are the quick steps:

mkdir -p  /var/OSimage/RHEL_6
 mount -o loop /ISO/rhel-server-6.4-x86_64-dvd.iso  /var/OSimage/RHEL_6

To make sure that the iso is mounted after each reboot make it permanent in the fstab file:

[root@RHEL-6 ~]# cat /etc/fstab

/ISO/rhel-server-6.4-x86_64-dvd.iso             /var/OSimage/RHEL_6 loop         defaults 0 0

Create a file:

vi /etc/yum.repos.d/rhel6.repo

[RHEL-6]
name=RedHat nterprise Linux 6
baseurl=file:///var/OSimage/RHEL_6
enabled=1
gpgcheck=0

save and exit

1 means enabled 0 means disabled. Here we are enabling the file:///var/OSimage/RHEL_6 as a yum repository.

Now run following two commands:

1. yum clean all

2. yum repolist

[root@RHEL-6 ~]# yum clean all

To test I installed samba - It will resolve the dependencies on ots own.

[root@RHEL-6 ~]# yum install samba

SSH Passwordless login

This is tested on RHEL-6

run the following command to generate the public key and copy it over to the system where you want to login without password.

[root@RHEL-6 .ssh]# ssh-keygen -t rsa
Generating public/private rsa key pair.
Enter file in which to save the key (/root/.ssh/id_rsa):
/root/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /root/.ssh/id_rsa.
Your public key has been saved in /root/.ssh/id_rsa.pub.
The key fingerprint is:
ea:86:92:04:ac:35:21:e8:bf:9d:3c:72:26:f4:46:3a root@RHEL-6
The key's randomart image is:

[root@RHEL-6 .ssh]# ll

type in the following command now :

ssh-copy-id -i ~/.ssh/id_rsa.pub  rsangvik@cluster1

You would get the following message: And the  .ssh/authorized_keys is created automatically with th command

Now try logging into the machine, with "ssh 'rsangvik@cluster1'", and check in:

  .ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

[root@RHEL-6 .ssh]# ssh rsangvik@cluster1
