[root@localhost Desktop]# cd /etc/yum.repos.d/

[root@localhost yum.repos.d]# ls

redhat.repo  rhel-source.repo  sabitha.repo

[root@localhost yum.repos.d]# 

specify static ip

[root@localhost yum.repos.d]# cat sabitha.repo 

[sabitha]

name=sabitha

baseurl=ftp://xxxx/pub/RHEL6

enable=1

gpgcheck=0

[root@localhost yum.repos.d]# 

test yum repolist

[root@localhost yum.repos.d]# yum repolist
