how to change default secureCRT appearance into Traditional color schemes

Default color scheme of SecureCRT is not eye friendly and if you work for long time with default color scheme your eye may be get tired . It is better to change color scheme into someting eye friendly. My suggestion is Traditional color schemes (Foreground is green and Background is black)

[1] Open the SecureCRT , click on " options " --> " Global options.. " . then you will get a window similar to the following

[2 ] select " General " --> " Default Session " --> " Edit Default Settings.. ", then you will have a window similar to the following

[3] Select " Appearance " --> and choose " Traditional "  form Current color schme drop down list . then click " OK " to apply the setting .

[4] Then SecureCRT prompt with a waring message like below, click " YES " and restart the SecureCRT

[5] SecureCRT color scheme is changed  , hooray !!!

how to add dvd based repository in rhel 6

Problem :- yum install [package..]    gives an error message similar to the following

[root@localhost ~]# yum install gcc
Loaded plugins: product-id, refresh-packagekit, subscription-manager
Updating Red Hat repositories.
...(output ommited)
No package gcc available   <-- here i'm try to install pacakage called 'gcc'
Error: Nothing to do

reason is we do not have access to RHN

Solution :- use DVD as base repository

[1]switch to the root

[shehan@localhost ~]$ su -
[root@localhost ~]#

[2]Create DVD based repo

[root@localhost ~]# vim /etc/yum.repos.d/iso.repo

Following text should be added to above file (iso.repo)


DVD based repository rhel 6

[3]mount installation DVD
make a directory called /mnt/cd and it should be similar to baseurl

[root@localhost ~]# mkdir /mnt/cd
[root@localhost ~]# mount /dev/cdrom /mnt/cd

[4]now try previous command again. it should work !
[root@localhost ~]# yum install gcc

baseurl of  " iso.repo " file  should be changed as
file://mnt/iso/Server     ( I created /mnt/iso directory)

mount command is
