Linux VM server and VM network configuration

Hi,
I have a Oracle Linux 5 server with Oracle VM Server 2.2.1 software installed. I downloaded OEL5 x86 VM template and set it up using the netmask, DNS and default gateway of the VM server machine. Now I realize I cannot access the internet from inside this Virtual Machine. So I think the DNS and gateway is not correctly setup.
Please note that I can ssh the VM from VM server.
Can you please guide me as to what DNS and gateway I should use for configuring my VMs? Do I need to set up an IP alais with different DNS.
My VM server ip is (some values changed) 99.44.95.115, DNS 213.133.98.98, Def gateway 99.44.95.97 , netmask 255.255.255.224
So for my first VM I am using ip 99.44.95.98, DNS 213.133.98.98, Def gateway 99.44.95.97 , netmask 255.255.255.224
Am I doing anything wrong. I am completely new to Linux and networking. So I am still learning.
Just a general idea would take me a long way.
Regards
CP

Netmasks are used to identify which portion of an IP address represents the network address and which portion represents the machine address. It affects your broadcast address and defines the range of addresses that you can communicate directly without the need of an IP gateway. You do not need an IP gateway to communicate with other hosts on the same subnet because they should be physically connected and hence receive each others broadcast in order to know how to translate IP to a machine address.
There are a couple of easy troubleshooting techniques. Like I mentioned in my previous post you can use the ping utility to check your IP communication. Open a terminal window and type e.g.: "ping 99.44.95.97". But make sure you do not have a firewall that block the ICMP protocol that the ping utility uses.
a) check if you can ping other machines on the same network.
You should be able to ping other hosts on the same subnet. If not, then you most likely have a problem with your IP configuration or network driver (hardware). Can you ping your own host? Is the network up?
b) check if you can ping the gateway.
If you cannot ping the gateway but a) works, then your IP gateway address is wrong or down.
c) check if you can ping the DNS.
Provided that a) and b) works, and you cannot ping the DNS server, then either the DNS address is wrong or down, or the IP gateway is not configured properly.
Please check the above in order to isolate the problem. The link to the Oracle documentation in the one of the previous replies will let you verify the vm.cfg file to check if you have configured bridged networking (default).
Posts about the same issue in different forums are usually not welcome here and the forum moderator might lock the thread. If you already have a thread I suggest you provide the link here in order for us to see what has already been done and make a note in the the old thread to continue here.

Linux install server and solaris 10

Hi,
I am trying to learn Solaris as a student. I bought a SPARC (Netra T105 UltrasparcII) server on ebay which requires a network install as there is no cd-rom, or keyboard.
I only have a linux box (like I said, I'm a stingy student) to use as an install server, there is a few tutorials out there to try and do this, but none for Solaris 10. I have been hacking away at this for days, but cannot get it to install. I have the sparc server using RARP and then getting the /etc/bootparams file and downloading the boot files, but it does not get to locating the jumpstart files or the install files (I dont know if I can install from the terminal using the keyboard (without jumpstart) - I have not got that far yet).
I always get this, like it cannot find the install directory, I was wireshark on the linux boot server and see loads of NFS traffic after the TFTP download, but cannot seem to see what part it actually at. I have a detailed log at the bottom from putty. Any help greatly appreciated.Cheers

You do have the option of running VMware on linux, and putting a Solaris 10 image on it, then using that VM as your boot server. But the problem you're displaying doesn't appear to be related to the linux server.

Software Updates Failing - Group Policy Overwritten - Server and Policy NOT CONFIGURED

I have seen a few posts about this issue and group policy overwriting the settings needed by SCCM with the wrong WSUS server. I checked the wuahandlerlog and found this error but it didnt have the server information.
"Group policy settings were overwritten by a higher authority (Domain Controller) to: Server and Policy NOT CONFIGURED"
The only coputer policy that applies to this system does not have WSUS entries in it. Windows update runs ok, and I deleted the WSUS registry keys that were set by a script and reinstall the client still getting the same error. I dont see any GPO local or domain, or reg keys that are setting anything. I have 10 other servers is the same AD container that this is working perfecly on.......
Suggestions????

Check out this GPO:
Computer Configuration -> Administrative Templates -> System -> Group Policy:
"Turn off Local Group Policy Objects processing"
The help text:
"This policy setting prevents Local Group Policy Objects (Local GPOs) from being applied.
By default, the policy settings in Local GPOs are applied before any domain-based GPO policy settings. These policy settings can apply to both users and the local computer. You can disable the processing and application of all Local GPOs to ensure that only
domain-based GPOs are applied.
If you enable this policy setting, the system does not process and apply any Local GPOs.
If you disable or do not configure this policy setting, Local GPOs continue to be applied.
Note: For computers joined to a domain, it is strongly recommended that you only configure this policy setting in domain-based GPOs. This policy setting will be ignored on computers that are joined to a workgroup."

Installing Mac OSX Server hangs at Network Configuration

Keyboard Layout: OK
Entering License: OK
Configuring Network:
Ethernet: Static
Airport: OFF
FireWire: OFF
Clicking on Forward to continue: The assistant keeps telling me "configuring network". Nothing happens. It is doing that for hours now.
I tried to connect with Server Admin tool: OK works.
The network is up and running, but the assistant is not continuing.
Any ideas?
Thanks for any help or suggestion

Smells vaguely of a DNS error or IP routing or a network connectivity problem.
What did you specify for your network settings, and particularly what was entered for the DNS server address? If you're not running DNS on your local network here, then enter no DNS servers as part of the prompting, and let Mac OS X Server establish its own default single-host DNS.
(You're not going to be able to use your ISP DNS here; those ISP DNS servers are not valid when you are establishing a server on a network behind a NAT gateway.)
I'd probably wipe the disk and boot from DVD and reload.

Host and VMs network configuration

Hi,
We have additional Network cards on the Host hyper-v server. Does it make sense to configure Host and VM network
in this way?
Host network configuration for Hyper-v virtual network switch:
1NIC ---
2NIC --- host_team_1
3NIC ---
4NIC --- host_team_2
VM network configuration:
host_team_1 ---
host_team_2 --- VM_team_1
Would we benefit from this configuration?
Thanks

It has to be in this way:
1NIC ---
2NIC --- host_team_1
3NIC ---
4NIC --- host_team_2
VM network configuration:
host_team_1 ---
host_team_2 --- VM_team_1
I understand your point. Just idea is if we have 4 physical NICs on host server for VMs, to configure 2 teams on host server and then one team on virtual machine.

Sunray unit connected to Linux Sunray server and Solaris Sunray Server

Hi,
Currently, I work in a development environment where there is two Sunray servers.
One server is running on Linux ubuntu and the second one is running on Solaris.
In order to connect to the wanted sunray server, the dhcp server is configured with the list of the mac address of the sunray units. So one sunray unit connects always to the same sunray server.
I would like to know if it is possible to have the two sunray server available from one sunray unit. And make the choice of sunray Server in function of the sun card inserted in the sunray unit.
- from my sunray unit A, if I insert my sun card AC I can open a session on the Linux server.
- from my sunray unit A, if I insert my sun card BC I can open a session on the Solaris server.
Thanks

You can do this by using an SRSS feature called "Automatic Multi-Group Hotdesking", or AMGH for short. For details read the "Regional Hotdesking" section in the SRSS Admin Guide and the manpages for utamghadm, ut_amgh_script_interface, ut_amgh_get_server_list and ut_amgh_free_server_list, and/or read the AMGH entries in [Bob Doolittle's blog|http://blogs.sun.com/bobd/].

Optimum E3200 and WRT160N Network Configuration

I recently purchased an E3200 router. I also have a WRT160N router. We have a rather large two story house, and it is not practical to run ethernet cable everywhere. I am attempting to configure the hardware I have for optimum performance given the current requirements of our family. Here is an attempt to summarize the current setup.
1st Floor
Cable Modem === Cable Box
=== E3200 === Blu Ray / Netflix
=== Laptop being used as media PC
Office PC === Wireless B/G/N Adapter
Second Floor
Kids PC === WirelessB/G/N Adapter
XBOX 360 === Wireless B/G/N Adapter
PS3 === B/G/N Wireless Adapter
XBOX 360 Headset === Bluetooth
Roaming
College Kid #1 Laptop === Wireless B/G/N Adapter
College Kid #2 Laptop === Wireless B/G/N Adapter
I can run ethernet cable from the E3200 to the Office PC without too much difficulty, since there is a basement underneath. I plan to do this. I can not run cable to any of the upstairs locations. I could set up the WRT160N as a wired AP, repeater or bridge at several different locations in the house. If I set it up on the first floor, it could be wired to the E3200, if this provided a significant performance advantage. If I put it upstairs, it will have to function as a repeater, possible a bridge. As a bridge, it could be wired to either the Kids PC or the XBOX 360. Connection to the PS3 is not a priority.
I would like to take advantage of the capabilities of the two routers to maximize the performance of our son's gaming, while not killing simultaneous multiple PC access. I have studied the process of setting up the ports for the XBOX/PS3 and am comfortable with the process, but am waiting until I optimize the router setup. I do not understand the technical aspects of how to force the XBOX/PS3 to connect with a particular router/band depending on how I utililize the WRT160N.
So, my questions are;
1. How can I best use the WRT160N to improve signal quality and network performance?
2. Depending on the answer to #1, how do I force the gaming systems to communicate directly with the E3200 (my assumption due to the performance) rather than the WRT160N?
I'm sure there will be more questions, but let's start with this. I appreciate any feedback anyone can provide.
Thanks,
Phil

1. You are going to have to use a cable between the two routers.
Go here... to connect two routers.
2. Assuming wireless connections just make two different SSID's between the two routers and connect to that specific SSID.

ATV2 and Manual Network Configuration Issue

Hi all,
Have 3 ATV2's in the house connected to latest gen TC via 5Ghz WiFi. Works great with one exception. From time to time, one of the ATV's loses the host iTunes library (connected via Home Sharing). If I go the the host and restart itunes - all is well again.
My solution was to try manual IP's for all of the ATV's and the Mac Mini host. Set the Mini to DHCP with manula IP- no problem.
However, when setting the ATV's, all three lose the "Movie" and "TV Shows" menu items as well as Youtube etc.. Meaning, they are obviously not connected to the WAN/Internet. They CAN see the host shared library.
Yes, it would seem my static config is wrong, BUT, I used the numbers already populated when I swtiched from DHCP. Would these numbers not be the ones assigned using DHCP? Would it not be safe to assume that simply assigning these manually would retain the same connectivity?
I switched all but the host mini back to DHCP and all is well again. However, I would like to go with a static set up. Am I missing somehting?
Thanks in advance!
Stuart

Thanks for the reply!
When you say "you also need to assugn adresses from the router" what exactly do you mean?
with exception of Mac Adress Control, I don't see a setting anywhere in Airport Utility that would allow me to assign specific IP's to specific devices...
In the past, simply setting an IP manually on a device would make it static on the network. No intervention on the TC was necessary.
Thanks again,
Stuart

My Apple TV suddenly stopped connecting to the server and the network. All devices in my house work just fine. Habe tried unpluggin, reset all settings, and disconnecting wireless and reconnecting, nothing works. Please help very frustrating

Tried all troubleshooting; unplugged, reset all settings, disconnected and reconnected wireless
The device woked fine for over a month until today
All other devices in my home are working just fine
very frustrating
please help

But my current sim card works just fine in my friends iphone 5...wouldnt the logic follow that the problem is with the device itself (the phone) and not the card?

Oracle 11g - Network Configuration check

Hi All,
This is my first time here and I am a newbie to Linux and Oracle installation.
I just finished installing Linux Enterprise version 5 ( provided by Oracle corp).
At the time of installation I did not do any type of network configuration and let the default network connection take effect.
After installing all the pre requirements for the Oracle 11g installation on my laptop I was stopped with a warning on the Oracle univesal Installer - product specific Prerequisite check.
This is what it gave me---
Checking Network Configuration requirements..
Check complete. The overall results of this check is : Not executed <<<
Recomendation : Oracle supports installation on systems with DHCP-assigned public IP addresses. However the primary network interface on the system should be configured with a Static IP Address in order for the oracle to function properly.See the installation guide for more details on installing the software on systems configured with DHCP.
I checked with the manuals and do not find any information about how to fix it.
The info given in the manual is
Installing on DHCP Computers
Dynamic Host Configuration Protocol (DHCP) assigns dynamic IP addresses on a network. Dynamic addressing enables a computer to have a different IP address each time it connects to the network. In some cases, the IP address can change while the computer is still connected. You can have a mixture of static and dynamic IP addressing in a DHCP system.
In a DHCP setup, the software tracks IP addresses, which simplifies network administration. This lets you add a new computer to the network without having to manually assign that computer a unique IP address.
Now i made some changes to the Network Config as root user and my Network configuration file looks like ( ie. /etc/hosts)
127.0.0.1 localhost StaticIP
It was previously something like
127.0.0.1 localhost.localdomain localhost.
As per the installation documents where ever i had references to localhost, i had left the localhost with the same name ' localhost' and have not changed it. Now it has StaticIP and I am not sure how to proceed.
What must I do?
I want to fix this error and also want oracle to work.
Thanks for your help!!

Thanks a lot guys to respond to this. I am using OEL5 ( supplied by Oracle Corp) and Oracle 11g. Installation of Linux takes about 40 minutes and installation of Oracle takes about an hour to 2 hours. Not sure why some RPM's do not show up on the CD's provided by Oracle.
So I tried to reinstall Linux . But the whole problem is, the Network Screens ( during installation) do not show up at all. It just skips that portion and goes to the Screen where there is the world Map and tells you to set up the time and date. I tried installing Linux many times and those Network configuration screens do not show up at all.
Here is my dilemma. After installing Oracle 11g, and immediately accessing the site https://localhost.localdomain:1158/em takes me into the OEM.
But after I shut down my machine and boot up again, I am unable to use the OEM's site https://localhost.localdomain:1158/em. Instead I get the message
===============================
Unable to Connect
Firefox can't establish a connection to the server at localhost.localdomain:1158
1. The site could be temporaily unavailable
2. If you are unable to load any pages, check your computer's network connection
3. If your computer is protected by firewall or proxy, make sure that firefox is permitted to access the Web.
===================================
I am thinking the problem is with 2. I do not have any firewall in my machine and i have also disbaled SELINUX.
I want to configure the computer so i can use the OEM in my Linux laptop.
My $ cat /etc/hosts gives
127.0.0.1 localhost.localdomain.
Please help me setup the Network so i can connect to 11g OEM.
And BTW this laptop is not even used to connect to the Internet.
Thanks

Trying to configure RedHat Enterprise 4.3 linux jumpstart server

I am trying to configure a system under RedHat Enterprise 4.3 linux to jumpstart
a Sun Ultra 60 and install Solaris 9. Web pages and SysAdmin 4/2005 article
"Portable JumpStart Environment" have not addressed my problem. I am using
Internet Systems Consortium DHCP Server V3.0.1. The bootblock is
delivered to the sun client and executes.
The entries in dhcpd.conf conform to those published in various Web
pages and the article "Portable Jumpstart".
The Solaris 9 OS distribution is exported thus:
/wks xxx.xx.xx.0/24(ro,wdelay,no_root_squash,mountpoint)
The load fails upon execution of .../Solaris_9/Tools/Boot/sbin/rcS
I think the problem may be with NFS. The mount request of the
exported filesystem appears to work:
rpc.mountd: authenticated mount request from sunxxx.xx.xx.xx:1023 for /wks/dist/sun/sparc/sunos5.9/9_404/Solaris_9/Tools/Boot (/wks)
The first errors reported are:
/sbin/rcS: /dev/null: cannot open
/sbin/rcS: /dev/null cannot create
I have captured the conversation between the linux jumpstart server and
the Sun client using tcpdump: tcpdump -vvv -s 192 host server and client.
I am not highly skilled at interpreting the tcpdump output; the cause of
the failure is not obvious to me.
I have successfully used a jumpstart server under Solaris 9 for quite some time. ISC DHCP is deployed on the Solaris jumpstart server.
Thank you,

While some have reported success doing this, I have heard of many failures. The common thread appears to be that when accessing device files, the Solaris client gets back something odd from the Linux NFS server.
Certainly this was the case for every attempt I knew about from a 2.2 kernel and earlier. I have see success reports, but do not have details about exactly which kernel or NFS patches were present.
This works fine from Network appliance and FreeBSD NFS servers, so I think there's some sticky point with the Linux NFS server that just doesn't handle the device files in the same manner.
See this newsgroup post (and the accompanying thread). It contains some discovered issues and some Linux servers that are reported to work.
