Solaris

Ebbi thanks a lot for the links. I am getting too much excited about it, and it appears that I am only few clicks away from the internet :-)

I think I understand my problem: my router doesn't supply a usable hostname, so it gets set to “unknown". To get around that, there are 2 methods, as described in the link you gave me http://www.rite-group.com/rich/solaris_dhcp.html.:

· DHCP has limited control
· DHCP has full control

Number 1:

If I wanted to try method 1 (as I'm not sure if my ISP has a habit of changing DNS name server IP addresses or not, but he/she could be), then there are few things I am not sure about:

1. I just copy the script and paste on my shell?.
2. Is DEFAULT_ADDR in the script my IP address?. How can I find my own IP address on a laptop not yet connected to Internet?. I remember I was told that IP add while installing Solaris but unfortunately did not write it down.
3. How do I know if I should be using leo0 or hme0 as my INTERFACE?.

Number Two:

Now let us suppose I wanted to try method 2 as well. This seems much easier i think: I just create two files with the TOUCH command?:

a)

> /etc/hostname.le0

b)

> /etc/dhcp.le0

As for the Host unknown, the page says “"Starting with Solaris 10, the preceding paragraph can be ignored. Instead, just make sure that the hostname you want to use is in /etc/nodename”.

I am on Solaris 10, so seems that I do nothing here.

Thank you very much for your time,

1. I just copy the script and paste on my shell?.

I meant this script here:

Dear All,

I was read this thread, and I can't to connect to Internet.
I'm not using DHCP for my Solaris OS but I was configurate my DHCP server and can read my Solaris IP, but I still can't connect to internet.
I'm able ping my pc (Solaris system) from other PC in my network and my DHCP server, I'm using ADSL modem for internet connection and using NAT by router (DHCP Server).Using Mozilla browser and in proxy configurating I'm using system proxy and direct to intenet, I was using manual proxy setting that direct connect to internet.
Any configuarting that not yet setting for connect to internet?

Thank's very much,

Regards,

1. Can you browse by IP address at all?

2. What is the output when you do "nslookup www.unix.com"?

3. what does your /etc/resolv.conf say?

4. Does your machine have a default route? What happens if you say "route get 82.195.131.187"

Thank's Porter,

yes that's good idea, I never thinking about that before ..
I try it and I can browse by IP address, but just in front page, when I click one link to other page, can't open.

Code:

# nslookup www.unix.com
;; connection timed out; no servers could be reached

I don't have this file, this default file? so need create this?

yes I have,
# route get 85.195.131.187
route to: 85.195.131.187
destination: default
mask: default
gateway: 192.168.1.81
interface: rtls0
flags: <UP,GATEWAY,DONE,STATIC>
recvpipe sendpipe ssthresh rtt,ms rttvar,ms hopcount mtu expire
0 0 0 0 0 0 1500 0

Now I can connect to internet but just using IP address , how to using name address?

my /etc/resolv.conf basically says....

Code:

nameserver 10.1.1.1

which is the internal IP of my ADSL router, my router has built in DNS proxy

You could mess about with DHCP or simply take an address from the DHCP range, (from your router) and set that manually:

/etc/hosts:
127.0.0.1 localhost
<ip address> <hostname> loghost

Put the same in /etc/inet/ipnodes too

/etc/resolve.conf
nameserver <routers IP address>

/hostname.<NIC type>
<hostname>

Where NIC type is hme0 use hostname.hme0, etc.

/etc/nodename:
<hostname>

/etc/defaultrouter:
<router's IP address>

/etc/netmasks:
<your IP range's netmask>

The netmasks files has info to help you in this regard.

Then reboot. Or:

ifconfig <NIC type> plumb
e.g: ifconfig hme0 plumb


ifconfig <NIC type> <IP address> up
ifconfig <NIC type> broadcast <broadcast address>

When your netmask is 255.255.255.0 your boradcast will be the first three octets of your IP address .255 so if your IP is 192.168.0.100 and your netmask is 155.255.255.0 then your broadcast will be 192.168.0.255

Finally setup a default route:

route add default <router's IP address>

so if your router's IP is 192.168.0.1 you'd do:

route add default 192.168.0.1

you can then check all is working with:

netstat -r

This will spit out about 4 lines, one of which should say "default" under "Destination" with "Gateway" being listed as your router's IP and the "flags" being UG

You should also check that /etc/nsswitch.conf

has hosts and ipnodes setup as follows:

hosts: files dns
ipnodes: files dns

This way you can add IP's on your local network, (or even google) to the local hosts table so you don't need to do a remote lookup each time. If you don't have DNS listed it wont check your DNS, even though nslookup will work.

I often find it usefull to actually add the DNS settings being used by my router to /etc/resolv.conf as it speads up the connection, but it can catch you out if the router changes DNS, etc. in which case you just have to update the entries.
