Hello,

I am new to Solaris. I have installed Solaris Express Developer Edition on my PC.
My PC is intel Pentium 4 with Intel Mother Board D865GSA which has on board Realtek LAN Card.
I connect to internet via DHCP.My ISP is VSNL(India).I am using Broadband connection.
Can anybody help me to configure internet on Solaris?

regards,
Prashant Poman.

Hi ,


First we need to find out if Solaris recognize your realtek card.

Solaris has two drivers built in for realtek NICs

rge - realtek gigabit ethernet 8169 , 8168 , 8167, 8136 chips

rtls - for fast ethernet 8139 chip.


The following PCI devices are recognized in SNV Build 82


rge "pci10ec,8169"
rge "pci10ec,8168"
rge "pci10ec,8167"
rge "pci16ec,0116"
rge "pci10ec,8136"
rge "pciex10ec,8136"

rtls "pci10ec,8139"
rtls "pci1186,1301"
rtls "pci1113,1211"



You can find out which device you have by running the scanpci command
as root in a terminal window.

Login as root and start a terminal window.

run the command:

/usr/X11/bin/scanpci

Is your Realtek NIC listed and is it one of those listed above ?

If you know that the NIC you have does use one of the recognized chips sets
but that the PCI ID listed by scanpci differs from the listed above you can
try to add the PCI ID to the /etc/driver/aliases file with an editor
and then reboot the system with a reconfguration boot .

you do a reconfiguration boot this way :

Logon to the system as root , start a terminal window.

# touch /reconfigure
# shutdown -y -g0 -i6

and the system will reboot.



If your chip set is totally different eg like a RTL8129 or RTL8100
you can try Muryama San's driver

http://homepage2.nifty.com/mrym3/taiyodo/eng/


or find a driver from the Vendor

http://www.realtek.com.tw/downloads/downloadsView.aspx?Langid=1&PNid=7&PFid=10&Level=3&Conn=2

Please ask again when you have figured out which chipset you machine actually has.

Hello,
I am also new to Solaris. I installed Solaris 10 8/07; Have Dell 4600 with P4, Intel pro 100 Lan+Modem 56 Cardbus II, and Intel Pro/100 VE Network connection; Have Cable Modem(using ethernet) but can't connect to internet; could it possibly be ethernet not working; can I ping for it;If it is not detected is there a way to try and configure it manually? Read the docs but didn't see it in there
Thanks,
Casey b

For "kcb1960"

The Intel Pro 100 VE is not a standard PCI card: see:

http://support.intel.com/support/network/adapter/pro100/pro100ve/sb/cs-008340.htm

when you run

# /usr/X11/bin/scanpci

Does the card show up in the list ?

The Intel Pro 100 is a a controller that is supported by Solaris as (iprb)

these are the PCI ID's recognized in the /etc/driver_aliases file

iprb "pci8086,1029"
iprb "pci8086,1229"
iprb "pci8086,1229.8086.1009"
iprb "pci8086,1229.8086.100c"
iprb "pci8086,1229.8086.1012"
iprb "pci8086,1229.8086.1013"
iprb "pci8086,1229.8086.1015"
iprb "pci8086,1229.8086.1016"
iprb "pci8086,1229.8086.1017"
iprb "pci8086,1030"
iprb "pci8086,1031"
iprb "pci8086,1032"
iprb "pci8086,1038"
iprb "pci8086,1039"
iprb "pci8086,103d"
iprb "pci8086,1050"
iprb "pci8086,1059"
iprb "pci8086,1068"
iprb "pci8086,1069"
iprb "pci8086,1092"
iprb "pci8086,1209"
iprb "pci8086,2449"
iprb "pci8086,27dc"

If a /usr/X11/bin/scanpci run in your PC shows up a different PCI ID
You need to add it to the list and then reboot the system with a reconfguration boot .

you do a reconfiguration boot this way :

Logon to the system as root , start a terminal window.

# touch /reconfigure
# shutdown -y -g0 -i6

and the system will reboot.

After that the best you can do is a "sys-unconfig " run that will shut down you PC.
The next time you start it up you will be asked all the questions of the
identity of your machine and all the questions on how you want
you network configured.

Hi,

Thanks for help.

I carried out the command

# /usr/X11/bin/scanpci

#

Thus my NIC chip is 8139.

What should I do next?

On Windows XP after fresh installation I just give my user name and password to connect to internet.My ISP is VSNL(India).I connect through DHCP.
What exact steps should I take considering the facts to connect to internet on Solaris 10?

Thanks!

hi,

Then the card should be configured in..

Do you have the devices:

/dev/rtls
/dev/rtls0

Does :

# modinfo | grep rtls

produce a single line with the rtls kernel modul info ?

If the answer is Yes to all of the above , I reccomend that you perform the
sys-unconfig procedure and then answer all the server and networking
questions that you will receive after the reboot.

just type

# sys-unconfig

And you will be asked if you relly want to and warned about the reboot.
After reboot you will need to answer all or parts of these questions.

Hi,

Thanks for help!

I carried out sys-unconfig.

But , I was unable to answer some of the questions.

Network Connection ---yes
DHCP---yes
IPv6---yes
Kerberos --no
Naming Seivce ---none
Domain Name--System Derived
NIS and NIS+ ---I don't know
DNS ---I don't know (also,I don't know ISP's IP address).

What should I do now?

Thanking You!

Prashant Poman.

Hi,

I executed the sys-unconfig and answered as follwows.

select a language -- 0(English)
select a locale --0 (English)
key board layout --US-English
Networked -- yes
use DHCP for rtls0-- yes
enable IPv6 for rtls0-- no
configure kerberos Security --no
Name Service -- None
NFSv4 Domain Configuration -- use the NFSv4 domain derived by the system

and so on..
it further asked my root password, date time settings etc.
What went wrong in above mentioned steps?

Do I need to contact my ISP to get it's IP address?

Thanking You!

The last version of the setup (your post 11 ) looks correct to me.

With a working broadband connection to the ISP the Solaris machine
should now broadcast for an IP address on the local Broadcast domain.
If there is a Router between the Solaris server and the ISP's network
the Router need to either answer the DHCP request it self or
forward the DHCP request to the ISP. this is usually done with the IP-Helper
function in Cisco Routers.

Ahem, what did you try to do ? /etc/driver_alises is not a program , you can t execute it
its is a file in the /etc directory which you can view with the " more" command and edit with an editor.

I suppose its much easier if you tell us what your problem is.

Which release/build you have installed.
Which hardware/ box it is.
Which network card you have,

the output of the /usr/X11/bin/scanpci command .

Thanks Tunla for your help in all this.

My issue was related, and your notes helped a great deal. In case this helps someone else,

MoBo is a GigaByte GA-X38T DQ6
DUAL RealTek 8168 gigabit interfaces

Initial install (Solaris 10 5/08) incorrectly detects and sets these up as '8169's in the /etc/driver_aliases file!

With this corrected (manual edit), and a sys_unconfig command issued, the driver loads and we begin to get the Network Setup survey on system startup.

But, even though the plumb -a command shows both interfaces up with appropriate settings, we cannot ping to anything else on the net. Hmmm.....

In addition, I cannot get DNS set up: the Network Setup reports an error:
config_nsswitch error -4, errno 2 No such file or directory.

Many thanks. Lou

Well unfortunately the implementataion of ethernet Hardware varies too widely.
And even if Solaris 10 5/08 is supposed to support 8168 chipset GiGaByte may have done
some thing to it like using a different PHY chip that the driver cant initialise.

how did you edit the driver_ aliases file ?

did you use the correct PCI bus identifier ?
PCI10ec is for the old sstyle PCI bus ( 10ec is the RealTek identifier )

PCIex10ec is for the new style PCI-Express BUS. which type NIC is it ? PCI or PCI Express ?

Maybe you should try Murayama San's GANI driver instead item 15 on the driver list below.

Lars - Thanks for your help with this.

PCI bus identifier: Hmm... This is a good point. I edited the driver_aliases by hand (is this adequate?), and assumed I was past this step once I saw the module loading.

I'll have to check this, but I think it may be on the PCIExpress BUS...

(Would I be overall better off using OpenSolaris, given its more dynamic state of development?)

Hi,

The number of usable NIC's is higer on OpenSolaris than on Solaris 10.
Solaris 10 comes with supportcontracts and problems are solved with patches
you apply which is great in production environments.

OpenSolaris is always ( as yet ) development snapshots of the codebase at a given point in time.
There is no patches. Solving a problem is done by Upgrading or Reinstalling a later Development
snapshot , which is called a Build level .

Will this solve you present problem with the NIC ?

Maybe but probably not.

The NUmber of interesting combination's of networking chips on motherboards
out of Taiwan is a marvel to behold.

Its probably less frustrating to get hold of a few of these and move them to the PC
one uses for the time being.

Tunla,

I've tried to fix this following your suggestions:

Background: [b]Gigabyte GA-X38T-DQ6[/b] mobo, with dual Realtek PCIExpress gigabit ethernet interfaces.

# scanpci indicates this machine has two RTL8111/8168B "PCIExpress" interfaces
Given this, I have modified the driver_aliases file to indicate Identifier: [b]pciex10ec[/b] instead of pci10ec as it had been.
Again, please note: the default Solaris install identified these as pci10ec 8169s - they are 8168s.

Ran sys-uninstall and rebooted... modinfo shows the rge Realtek module loaded (with info field value 215 - what does this mean?)

# ifconfig -a shows both interfaces up, with IP and MAC addresses assigned.
# ifconfig -a plumb indicates SIOCSLIFNAME is set up for both interfaces.

However, still cannot ping anything on our net. Strangely, our router does receive frames from this machine! So, something is - sort of - working!

An aside: am still getting the error at configuration after sys-unconfig: error while trying to configure the name service switch file: config_nsswitch error -4, errno 2, No such file or directory. I can manually create the nsswitch.dns file, of course, but this error is weird...

I'd be happy to install openSolaris, if I had any reason to think it would solve my problem. (By the way, we have a lot of experience with Solaris (Commercial) on SPARC hardware; this is our first x86 install, however...)

Can you suggest the next thing I might try here?

Thanks again in advance, Lou

All I can say is a lot of personal experiences really,

I have a machine that contains an 8169 . This machine only works on the net if it is cold booted into solaris . A reboot from windows does not work .

you could also try to put FQDN names in the /etc/hosts file and in the
/etc/hostname.rge0 /etc/hostname.rge1 files.

RGE interface is a bit iffy, Intel e1000g has in my experience always been rock solid.
