[SOLVED] internet is not wokring

deep27ak · 01-22-2012, 11:49 PM

Hello all

I am really new to solaris. This is the first time I installed solaris 10 and I am having internet connectivity issue.

I am able to ping all the IP in network including the gateway and DNS but I am no connected to internet.

Code:

# ifconfig -a
lo0: flags=2001000849<UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL> mtu 8232 index 1
        inet 127.0.0.1 netmask ff000000
e1000g0: flags=1000843<UP,BROADCAST,RUNNING,MULTICAST,IPv4> mtu 1500 index 2
        inet 192.168.0.92 netmask ffffff00 broadcast 192.168.0.255
        ether 0:50:56:8b:0:e

Code:

# cat /etc/resolv.conf
nameserver 4.2.2.2
nameserver 8.8.8.8

Code:

# cat /etc/defaultrouter
192.168.0.1
bash-3.00#

Code:

# cat /etc/nodename
solaris-hotwire
bash-3.00#

Code:

# cat /etc/inet/netmasks
#
# The netmasks file associates Internet Protocol (IP) address
# masks with IP network numbers.
#
#       network-number  netmask
#
# The term network-number refers to a number obtained from the Internet Network
# Information Center.
#
# Both the network-number and the netmasks are specified in
# "decimal dot" notation, e.g:
#
#               128.32.0.0 255.255.255.0
#
192.168.0.0     255.255.255.0

Code:

bash-3.00# ping 192.168.0.1
192.168.0.1 is alive
bash-3.00# ping 4.2.2.2
4.2.2.2 is alive
bash-3.00# nslookup google.com
Server:         4.2.2.2
Address:        4.2.2.2#53

Non-authoritative answer:
Name:   google.com
Address: 74.125.235.17
Name:   google.com
Address: 74.125.235.18
Name:   google.com
Address: 74.125.235.19
Name:   google.com
Address: 74.125.235.20
Name:   google.com
Address: 74.125.235.16

Code:

bash-3.00# ping google.com
ping: unknown host google.com

what am I missing??

Try:

Code:

$ping www.google.com

make sure your gateway and DNS is correct. If that DNS isnt working try different ones.

Thanks for your reply

But the DNS I am using is GOOGLE dns and it is working for all the other linux distributions on all workstations

You are missing a proper /etc/nsswitch.conf hosts configuration.

It should be:

Code:

hosts: files dns

deep27ak · 01-23-2012, 04:05 AM

I made the following changes but still no good news

Code:

#vi /etc/nsswitch.conf
passwd:     files
group:      files
hosts:      files dns
ipnodes:    files
networks:   files
protocols:  files
rpc:        files
ethers:     files
netmasks:   files
bootparams: files
publickey:  files

Double check. It should work.

I restarted the machine and now its working

but last time I restarted my network but still the internet was not working

Code:

#svcadm restart network

please correct me if I am wrong, this is the command to restart the network?

And there is one more confusion
I have two resolv.conf inside my etc

Code:

#/etc/resolv.conf
and
#/etc/resolv.conf~

I have no idea about the other one as it is a blank file
should I delete that file?
and it is created?

Likely not enough given the fact it wasn't sufficient. I actually never ran that command and believe network is just a milestone, not a real restartable service.
The only service that was needing to be restarted was probably "name-service-cache".

You can delete it, especially if it is empty.

It is probably a backup file created by the editor you used.

deep27ak · 01-23-2012, 07:35 AM

then what is the command in solaris to restart the network after I make changes?

like in linux we have

Code:

#service network restart

there must be some similar command for the same purpose?

jlliagre · 01-23-2012, 07:53 AM

The closest equivalent would probably be

Code:

svcadm restart network/physical
