Help to set IP. 'SIOCADDRT: No such process .'

[sanvg]

Hi all..

Im trying to set the following configuration on my debian5.0 machine.

address 172.27.111.27
netmask 255.255.255.248
gateway 172.28.112.41

But, it gives the follows when i restart the network.

Reconfiguring network interfaces...SIOCDELRT: No such process
SIOCADDRT: No such process
Failed to bring up eth0.
done.

Is their any issue related to netmask configuration?
Help me to solve this.

I'm not sure if the netmask is right, looks like a /29 network, you sure this is right? usually home network is 255.255.255.0

in either case, looks like something is configured incorrectly, post entire contents of /etc/network/interfaces file

also post output of lspci -vnn and lsmod in CODE TAGS

[sanvg]

Yes, you are right. It's /29 network. I have to configure this set only.

My /etc/network/interfaces content is

auto eth0
iface eth0 inet static
address 172.27.111.27
netmask 255.255.255.248
gateway 172.28.112.41

Output of lspci -vnn is contains following ethernet controller data

01:00.0 Ethernet controller [0200]: Realtek Semiconductor Co., Ltd. RTL8101E/RTL8102E PCI Express Fast Ethernet controller [10ec:8136] (rev 01)

Then, the output of lsmod is attached as lsmod.txt

thanks

this configuration isn't right, if you are using a /29 network, that means you only get 32 IP's

that gateway is not inside the network of your IP, it has to be something reachable within the subnet, where are you getting your network configuration information from?

[sanvg]

the configuration is given by one of the authorized switch center to connect my software as client.

Can you people please explain or refer any link to understand what is wrong with this configuration?

[coopstah13]

172.27.111.27 and 172.28.112.41 are not even close to being in the same network with the subnet mask you are using, the gateway address must be within 32 IPs of the network address you have in order to be reachable based on your subnet mask

i would double check the configuration with who gave it to you
