New 'localhost.localdomain:1 (admin)' desktop is localhost.localdomain:1

Creating default startup script /home/admin/.vnc/xstartup

(Login as root first)

[root@server ~]# iptables -I INPUT -m state --state NEW -m tcp -p tcp --dport 5901 -j ACCEPT

[root@server ~]# service iptables save

iptables: Saving firewall rules to /etc/sysconfig/iptables:[  OK  ]
