hai everybody,

the seaquece of steps i have done is :

i installed FC4,then i updated it using 'yum update'.
then i disabeld sendmail as : '/etc/init.d/sendmail stop'
then i disabled firewall as : '/sbin/services iptables stop'
i also got a ip address from 'no-ip.com' as
203.193.129.103 zimpro.no-ip.info
and my network configuration is as follows
ip 203.193.129.103
subnetmask 255.255.255.224
default gateway 203.193.129.103
primary DNS 165.21.83.88
and my /etc/host files looks like this :
# Do not remove the following line, or various programs
# that require network functionality will fail.
127.0.0.1 localhost.localdomain localhost
203.193.129.103 zimpro.no-ip.info zimproject

and

[root@zimpro ~]# hostname
zimpro.no-ip.info
[root@zimpro ~]# domainname
(none)

then i started installing zimbra n/w edition as follows :

[root@zimpro ~]# cd ..
[root@zimpro /]# cd home/manjunath
[root@zimpro manjunath]# cd zcs-NETWORK-3.0.1_GA_160.RHEL4.tgz_FILES/zcs
