Configuration of the Network through Files (DHCP)

Very easy... Please have a look to my previous post...

root@vsolutions:/export/home/rudy/bin# cat cleanNetwork
rm /etc/hostname.rge0
rm /etc/defaultrouter
cp /etc/nsswitch.default /etc/nsswitch.conf
rm /etc/dhcp.rge0
rm /etc/resolv.conf

root@vsolutions:/export/home/rudy/bin# cat enableDHCP
echo "...run as root..."
/export/home/rudy/bin/cleanNetwork
touch /etc/hostname.rge0
touch /etc/dhcp.rge0

root@vsolutions:/export/home/rudy/bin# ./enableDHCP
...run as root...
rm: cannot remove `/etc/dhcp.rge0': No such file or directory

There was no /etc/dhcp.rge0 and it ns normal that the script cleanNetwork did complain...

...Reboot the machine...

Configuration of the Network through Files (ip is static)

I know I know you are all experts in the matter of networking...

But if you are new to OpenSolaris or would like some refreshment related to the way to access a network in OpenSolaris, this is the post you need !

1.The Network Interface Card

It is sometimes frustrating but you have to check if your network card is seen by OpenSolaris... You have also to retrieve the nic.

rudy@vsolutions:~$ ifconfig -a
lo0: flags=2001000849 mtu 8232 index 1
inet 127.0.0.1 netmask ff000000
rge0: flags=1000843 mtu 1500 index 2
inet 164.15.227.15 netmask ffffff00 broadcast 164.15.227.255
lo0: flags=2002000849 mtu 8252 index 1
inet6 ::1/128

In the previous example, the network interface (or nic) is seen by OpenSolaris and an IP address was assigned.

You can retrieve a reference to the nic in /var/adm/messages.

rudy@vsolutions:~$ grep rge0 /var/adm/messages | more
Dec 23 05:42:04 opensolaris rge: [ID 801725 kern.info] NOTICE: rge0: Using MSI i
nterrupt type
Dec 23 05:42:04 opensolaris mac: [ID 469746 kern.info] NOTICE: rge0 registered
Dec 23 05:43:05 opensolaris in.routed[546]: [ID 749644 daemon.notice] rge0 has a
bad address 0.0.0.0
Dec 23 05:43:06 opensolaris mac: [ID 435574 kern.info] NOTICE: rge0 link up, 100
Mbps, full duplex

If you know the nic you can use prtconf...

rudy@vsolutions:~$ prtconf -v | grep rge0
dev_path=/pci@0,0/pci8086,2942@1c,1/pci1028,2c0@0:rge0
dev_link=/dev/rge0

2.The Configuration

You have to be root to execute the commands ! Please backup your files ! Or play with beadm !!!

root@vsolutions:~# cat /export/home/rudy/bin/enableNetwork
# change the following before rebooting your machine !
IP=XXX.XXX.XXX.XXX
GATEWAY=YYY.YYY.YYY.YYY
DNS=ZZZ.ZZZ.ZZZ.ZZZ

echo "...configuring the network network..."
echo "ip address : " $IP
echo "gateway : " $GATEWAY
echo "dns : " $DNS
echo "...using dns..."

echo "$IP" > /etc/hostname.rge0
echo "$GATEWAY" > /etc/defaultrouter
cp /etc/nsswitch.dns /etc/nsswitch.conf
echo "nameserver $DNS" > /etc/resolv.conf

Reboot and that should do the trick...

Network Auto-Magic and nsswitch.conf

Rudy is back ! It is a long time that I didn't write a new blog entry... Here we go ! I left Sun Microsystems and started my own and little company named VSolutions... Little because there is only 1 person inside : me ! I am still a Sun fan and will continue to make your life easier...

I bought my own laptop, a Dell Vostro 1720 and installed OpenSolaris 2009.06.
I will create a specific entry on the Dell Vostro... But I reviewed on the Internet that some people used Network Auto-Magic to configure the network and they had problems with dns. Especially using a browser like Firefox.

If you configured dns, used nslookup and it does not work using Firefox it is because the file /etc/nsswitch.conf was not updated to use dns !

Do the following as root :

cp /etc/nsswitch.conf /etc/nsswitch.conf.orig
cp /etc/nsswitch.dns /etc/nsswitch.conf

Restart your browser (by example)

That should do the trick !

OpenSolaris 2008.11 - CUPS - Brother HL-2030 USB

I was a little bit disappointed... I plugged my laser printer Brother HL-2030 ( USB ) and enabled cups and played a little bit with the cups website but was not able to print anything as the printer goes offline ! S...

After reading several sources what have to be done :

• enable cups

The package SUNWcups was not installed. Start the Package Manager and type cups in the "search field". I installed the 3 packages to be sure : SUNWcups, SUNWcups-libs and SUNWpycups(if I remember well this one was already installed).

Query the print service and cups is enabled.

root@catalogne:~# print-service -q
active print service: cups

If cups is not enabled :

print-services -s cups

• enable your user to use the cups website(when authentication is required)

Getting Admin rights to modify CUPS settings

You have to be in the group "sys".

root@catalogne:~# cat /etc/group | grep sys:
sys::3:root,bin,adm,rudy

In this example, the user "rudy" is in the "sys" group.

"THIS IS TEMPORARY ! ROOT CANNOT AUTHENTICATE INTO CUPS"
please remove later your user from "sys" !

• Access the cups website and create a new usb printer
  

example : http://localhost:631

This will create the necessary configuration for a test1 printer.

• Modify the cups configuration

Add "FileDevice Yes" in cupsd.conf(backup the file before).

root@catalogne:/etc# more /etc/cups/cupsd.conf
#
# "$Id: cupsd.conf.in 7199 2008-01-08 00:16:30Z mike $"
#
# Sample configuration file for the Common UNIX Printing System (CUPS)
# scheduler. See "man cupsd.conf" for a complete description of this
# file.
#

# RUV
FileDevice Yes
...
...
...

Modify printers.conf

root@catalogne:~# more /etc/cups/printers.conf
# Printer configuration file for CUPS v1.3.7
# Written by cupsd on 2009-04-02 20:04

Printed a test page !!!

That's all for today !

swap space on Solaris 10(in Virtual Box)

Can we define space using a zfs pool... Seems not...

I did the exercise but swap -a did not accept to add the files I created with the command mkfile !
It was a little bit trickier that I thought because I was using a Solaris 10 created in Virtual Box.

• Create a new disk in Virtual Box and assign the disk to you Virtual Machine
  

• Boot the Virtual Machine(Solaris) and execute a reboot -- -r

reboot -- -r is necessary to make Solaris see the new disk.

• use format and fdisk to partition the new disk

-bash-3.00# format
Searching for disks...done

• use newfs to create the filesystem

-bash-3.00# newfs /dev/dsk/c1d1s0
newfs: construct a new file system /dev/rdsk/c1d1s0: (y/n)? y
Warning: 2370 sector(s) in last cylinder unallocated

8260128, 8358560

• mount the filesystem

first create a directory where to mount then mount

-bash-3.00# mkdir extraswap
-bash-3.00# mount -F ufs /dev/dsk/c1d1s0 /extraswap/

• create the swap space and add it to the system

-bash-3.00# mkfile 1g swap1
-bash-3.00# mkfile 1g swap2
-bash-3.00# mkfile 1g swap3
-bash-3.00# mkfile 900m swap4
-bash-3.00# swap -a /extraswap/swap2
-bash-3.00# swap -a /extraswap/swap2
-bash-3.00# swap -a /extraswap/swap3

Moving Virtual Box Machines

This document does not show the way to make a Virtual Box configuration see a Virtual Box machine that was copied from somewhere. What I propose(temporarily) is to rename the current Virtual Box directory(.VirtualBox) and then copy the files from the Virtual Box machines where you did the copy. At this time, why would you run 2 machines at the same time ?

• make a copy of the current Virtual Box
  
• start Virtual Box
  

accept the license agreement
enter your name and email address

• exit VirtualBox
  

• copy the files
  

rudy@catalogne:/tank/VirtualBox$ ls
compreg.dat HardDisks Machines VirtualBox.xml xpti.dat

tank is a ZFS filesystem on an external disk(from where the VM was copied).

rudy@catalogne:/tank/VirtualBox$ cp -pr HardDisks /export/home/rudy/.VirtualBox
rudy@catalogne:/tank/VirtualBox$ cp -pr Machines /export/home/rudy/.VirtualBox
rudy@catalogne:/tank/VirtualBox$ cp -pr VirtualBox.xml /export/home/rudy/.VirtualBox/

• start Virtual Box(new VM copied)

rudy@catalogne:~$ VirtualBox

That should make the trick ! You have now access to the VM that was moved !
