The error is stating No route to host (113). So can you ping this ip address?
Check to see if the firewall is up and running on this device. If it is disable it and try to connect again.

yes ofcourse i can ping the ip address pc two...
so which way so i can disable the firewall setting related with port that used in the vncviewer?

First we need to check if the VNC Server is running with;

Code:

service vncserver status

If it isn't running then start it and try to connect again. If you still cannot connect the next step would be to check if the firewall is running with;

Code:

service iptbales status

If it is running you can shut it off for testing and then try to connect again.

To stop it use;

Code:

service iptables stop

And you can restart it by replacing stop with start.

The port you need to open is 5900. How this is configured on your system depends on how your firewall is setup. RH likes to do some funky firewall setup with is useless and serve only to confuse the beginners.

Post your firewall setting from /etc/sysconfig/iptbales and I could tell you what needs to be setup.

when i check the vncserver run or not :

[root@masdeddy ~]# service vncserver status
vncserver: unrecognized service

and then i try to ping :

[root@masdeddy ~]# ping 192.168.1.3
PING 192.168.1.3 (192.168.1.3) 56(84) bytes of data.
64 bytes from 192.168.1.3: icmp_req=1 ttl=64 time=1.38 ms
64 bytes from 192.168.1.3: icmp_req=2 ttl=64 time=0.262 ms
64 bytes from 192.168.1.3: icmp_req=3 ttl=64 time=0.247 ms

4 packets transmitted, 4 received, 0% packet loss, time 3002ms
rtt min/avg/max/mdev = 0.247/0.537/1.382/0.488 ms

so while I conclude no problem on the connection between computer
then i checked the iptables...

[root@masdeddy ~]# service iptables status
Table: filter
Chain INPUT (policy ACCEPT)
num target prot opt source destination
1 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0 state RELATED,ESTABLISHED
2 ACCEPT icmp -- 0.0.0.0/0 0.0.0.0/0
3 ACCEPT all -- 0.0.0.0/0 0.0.0.0/0
4 ACCEPT udp -- 0.0.0.0/0 224.0.0.251 state NEW udp dpt:5353
5 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited

Chain FORWARD (policy ACCEPT)
num target prot opt source destination
1 REJECT all -- 0.0.0.0/0 0.0.0.0/0 reject-with icmp-host-prohibited

Chain OUTPUT (policy ACCEPT)
num target prot opt source destination

then i start and stop the iptables
and this is my firewall setting :

[root@masdeddy ~]# cat /etc/sysconfig/iptbales
cat: /etc/sysconfig/iptbales: No such file or directory
[root@masdeddy ~]# cat /etc/sysconfig/iptables
# Firewall configuration written by system-config-firewall

*filter

COMMIT

From what I can tell from above you don't have the VNC Server installed.
Use yum to install it.

oh... i wasn't careful, so i concluded when i installed vncviewer at ubuntu it will be through install vncserver too but different with fedora family
