Hi

well just install ubuntu 7.10 on my Toshiba satellite M35

output of /etc/network/interfaces file is

auto lo
iface lo inet loopback


iface eth0 inet static
address 172.25.9.148
netmask 255.255.255.192
gateway 172.25.1.1

auto eth0

i did couple of things, i bought friends router, and configured my eth0 to dhcp mode and it accepted ip address from router and i was able to ping router.

the problem is that i am not able to ping default gateway and dns provided by my ISP, if i am able to do it, i will be able to connect

help plz.

thanks.

It looks like there isn't any problem detecting your hardware which seems to be working fine. If it wasn't detected then you wouldn't even have the option to apply static settings. Your default gateway and name server addresses should be set to the address of the router. The router should then forward on any requests to your ISP. I suggest you just use the DHCP information from the router to avoid any problems.

kool124 12-15-2008 04:24 AM

my ISP cable comes directly to my lan card, router was just to test if my interface is working or not, my ISP cable comes directly to my eth0

well so when i am trying to ping default gateway and dns i am not able to do it, any suggestion what might be wrong

asymptote 12-15-2008 04:29 AM

Can't you just use the DHCP settings from your ISP? In America ISP's usually have a DHCP server that sends us the gateway and dns server addresses. Usually you will not see them reply to PING for security reasons. Can you just connect via DHCP and see if you can navigate to websites?

kool124 12-15-2008 04:31 AM

i have been provided static ip by my isp

well i can ping my default gateway and dns server in windows xp machine which i m using right now

asymptote 12-15-2008 04:33 AM

When you enter the static information from your ISP in /etc/network/interfaces you cannot connect to the ISP...is that correct?

kool124 12-15-2008 04:39 AM

yes, its not getting connected

asymptote 12-15-2008 04:45 AM

I apologize if this is a dumb question but when you entered the static information did you restart networking with
Code:

/etc/init.d/networking restart
Other than that I'm not sure what the problem could be. As long as the network devices (such as the routers & switches) are configured properly then anything else would be server based issues like if your ISP required that you use a Windows machine and join their domain. Can you just try receiving DHCP settings from the ISP? Sorry if these are dumb suggestions but this issue boggles my mind.

asymptote 12-15-2008 04:48 AM

What static settings did the ISP give you? Any chance the netmask is incorrect?

binary_pearl 12-15-2008 05:02 AM

A couple things to try:

1. ifconfig and route commands:

route del default # Delete the default gateway, just to be sure
ifconfig eth0 172.25.9.148 netmask 255.255.255.192
route add default gw 172.25.1.1


2. Make sure eth0 is the correct interface:
ethtool eth0

Make sure you see the following at the end of the ouput:
Link detected: yes

If you see 'no' for the Link detected, try eth1 and eth2. Although judging by the packets sent and received eth0 is probably the correct interface.

doctorcisco 12-17-2008 12:19 AM

OK ... your default gateway/ip address/subnet mask are unusual, because 172.25.1.1 is not in the same subnet as your host address 172.25.9.146 255.255.255.192. Please double check your Windows XP machine and make sure these settings are correct, and please post the output of ipconfig /all from Windows here.

If they are correct, can you ping any other machines between addresses 172.25.9.129 and 172.25.9.191? Also, please post the output of the following commands:

route
arp -a

kool124 12-18-2008 07:06 AM

hi,


yes you are right, i already changed my subnet mask to 255.255.0.0
and i am able to ping my gateway

but setting that i used earlier r correct one and i am using that setting only in my windows xp

thanks.

kool124 12-18-2008 07:08 AM

also one thing i was able to view same workgroup computer with earlier setting, and yes was able to ping other machine with same settings
