How to specify subnet mask in netconf

I am editing netconf with following :

ROUTE_DESTINATION[2]=135.243.68.0
ROUTE_MASK[2]=255.255.255.224
ROUTE_GATEWAY[2]=172.29.4.1
ROUTE_COUNT[2]=1
ROUTE_ARGS[2]=""

---------------------

But when restart net daemon, it gives error:

egtmast,sys,root # /sbin/init.d/net stop
egtmast,sys,root #
egtmast,sys,root # /sbin/init.d/net start
ERROR: Failed to add route entry because its interface is not
yet initialized. May need to add this route entry with
a route commad after the interface is up :
netmask: bad value
egtmast,sys,root #

----------------------------

I must delete subnet mask not to get error:

ROUTE_DESTINATION[2]=135.243.68.0
ROUTE_MASK[2]=""
ROUTE_GATEWAY[2]=172.29.4.1
ROUTE_COUNT[2]=1
ROUTE_ARGS[2]=""

--------------------------

So , how will system suppose subnet mask is 255.255.255.224 ?. How can i specify subnetmask in netconf?

You need not mention the netmask as it is optional.

Without mentioning the netmask, Please start the network and paste the output of netstat -in and netstat -rn.

Re: How to specify subnet mask in netconf

That's right!

I want IPs between 135.243.68.0 and 135.243.68.31 ping my server.

But If I define as below:

ROUTE_DESTINATION[2]=135.243.68.0
ROUTE_MASK[2]=""
ROUTE_GATEWAY[2]=172.29.4.1
ROUTE_COUNT[2]=1
ROUTE_ARGS[2]=""

--------------------------

I think range 135.243.68.0-255 will ping my server wtih this configuration. So is there a way to fix this even if after reboot?
