now whn i type route -n in ssh to sme server i get


Destination Gateway Genmask Flags Metric Ref Use Iface
(222.111.9.0) 0.0.0.0 255.255.255.0 U 0 0 0 eth0
(127.0.0.0) 0.0.0.0 255.0.0.0 U 0 0 0 lo
(0.0.0.0) 222.111.9.30 0.0.0.0 UG 0 0 0 eth0

the host file in sme server is as follows..

try netmask 255.255.255.255

ermm looks like u attempting to use korean ip_address in your LAN

dude. if LAN u LAN IP eg

(1)192.168.0.X/255
(2)192.168.1.X/255

then u can use netmask 255.255.255.0

You are trying to assign a default gateway, correct? If so, the target used in the "route" command is 0.0.0.0/0. So...

Code:

route add -net 0.0.0.0/0 gw 222.111.9.30
-or- using the non CIDR method

Code:

route add -net 0.0.0.0 netmask 0.0.0.0 gw 222.111.9.30
BTW: If I understood your post correctly, then the default gateway of this system is already set to 222.111.9.30

Destination Gateway Genmask Flags Metric Ref Use Iface
(222.111.9.0) 0.0.0.0 255.255.255.0 U 0 0 0 eth0
(127.0.0.0) 0.0.0.0 255.0.0.0 U 0 0 0 lo
(0.0.0.0) 222.111.9.30 0.0.0.0 UG 0 0 0 eth0 <----

Basically, the output from ping is stating it is unable to reach your network. duh!

Your route tables look good, although I do not know why the destination field of the "route -n" command is shown in parens.

1) Are you sure your network address is correct? i.e. 222.111.9.0/24

2) Are you sure the default gateway is correct for your network address?

3) Are you sure layers 1 and 2 of the network OSI model are working? i.e. cable plugged into NIC and a link lite.

4) type: ifconfig eth0
Check to see if the interface is transmitting/receiving data -or- if there are any errors associated with the interface. Also, is the broadcast address correct?

Thats all I got.
Good Luck!

shueib 12-29-2005 07:27 AM

yes the network address is correct ....

no i have written in parens for everyone to recognize its all congested thts y..

yes whn i ping 222.111.9.30 4m ...SME Server ie...222.111.9.1 it gets reply..

before adding the route i was getting message .for ping www.yahoo.com as unknown host ...after adding route im getting as..destination host unrechable.

by doing ifconfig i get

my ip as 222.111.9.1 netmask 255.255.255.0 and broadcast as 255.255.255.0

Check out your broadcast address. Based on your network address/netmask, it should be 222.111.9.255

shueib 12-29-2005 09:43 AM

oops broadcast is 222.111.9.255 ......any idea ...where the probs must be

shueib 12-30-2005 12:22 AM

tried the following command...

route add -net 222.111.9.1 gw 222.111.9.30 netmask 255.255.255.255 dev eth0

my route table shows.. route -n

Destination Gateway Genmask Flags Metric Ref Use Iface
222.111.9.1 222.111.9.30 255.255.255.255 UGH 0 0 0 eth0

0.0.0.0 222.111.9.30 0.0.0.0 UG 0 0 0 eth0

and whn i ping www.yahoo.com it shows..

???????????? any ideas.....................................

Your routing table should look like below:

Code:

Destination    Gateway        Genmask        Flags Metric Ref    Use Iface
222.111.9.0    0.0.0.0        255.255.255.0  U    0      0        0 eth0
127.0.0.0      0.0.0.0        255.0.0.0      U    0      0        0 lo
0.0.0.0        222.111.9.30    0.0.0.0        UG    0      0        0 eth0

Hope eradication of that first entry in the route table you had above clears your problem.
