MD3000 - Change Access From Host to Host-Group
I've got a Hyper-V partition on an MD3000 called "HyperV-CSV".
At present, in the "Host-to-Virtual Disk Mappings" it is only accessible by "Host HyperV1".
I'm trying to allow host HyperV2 access as well, and without causing problems. What I have done is created a Host Group called "HyperV-Group" where both HyperV1 and HyperV2 are members.
So what I think I need to do is change the access of the Virtual Disk from "Host HyperV1" to "Host Group HyperV-Group".
My questions though - will this disconnect the disk from HyperV1 briefly while making the change? Will this properly allow both HyperV1 and HyperV2 to access this virtual disk?

Hi AlexMtl,
It seems the host accesses internet via wifi ,right ?
The host still can access internet after removing bridge connection then reboot , right ?
If it is the case , please refer to following setps :
1. remove bridge from wifi then reboot it to ensure host can access internet
2. create a new internal virtual switch
3. share wifi connection to the new Vswitch (right click wifi connection --> properties --> sharing --> check "allow another network ..." and select the new internal Vswitch in the drop list)
4. configure an IP for the new Vswitch same subnet as VM's IP
5. configure VM's gateway same as the IP of new Vswitch (also configure the DNS server IP for VMs)
Hope this helps

Hello All,
we have created shared folder on multiple client machine in domain environment on different 2 OS like-XP,Vista, etc.
from some day's When we facing problem when we are access from host name that shared folder is accessible but same time same computer when we are trying to access the share folder with IP it asking for credentials i have type again and again
correct credential but unable to access that. If i re-share the folder then we are access it but when we are restarted the system then same problem is occurring.
I have checked IP,DNS,Gateway and more each & everything is well.
Pls suggest us.
Pankaj KumarHi,
According to your description, my understanding is that the same shared folder can be accessed by name, but can’t be accessed be IP address and asks for credentials.
Please try to enable the option below on the device which has shared folder:
Besides, check the Advanced Shring settings of shared folder and confrim that if there is any limitation settings.
Best Regards,
Eve Wang

Qemu-kvm: network access from host to guest
I need ssh and http access from my host (Arch) to the guest (other Linux). I've failed at setting up Tap networking as described in the wiki. I don't need to have the whole LAN access the guest, so is there another way the host can access the guest? Using the guest's IP of 10.0.2.15 doesn't work, but I'm hoping there is a way to do it.
Thanks.Mr.Elendig wrote:Bridging is the best way todo it, so you should give us some more info on your atempt at it, so that we can help you fix it.
Ok, I've followed the instructions from the wiki.
One problem is that I'm on a laptop. eth0 is wireless and eth1 is wired. I chose to use eth1 since I thought it'd be easier to get working on one device before trying to make it work on both.
1. bridge and tun modules are loaded from rc.conf
2. In /etc/conf.d/bridges I have this:
bridge_br0="eth1"
BRIDGE_INTERFACES=(br0)
3. In /etc/rc.conf I changed my networking portion to this:
eth1="eth1 up"
br0="dhcp"
INTERFACES=(eth1 br0)
4. In /etc/udev/rules.d/65-kvm.rules I have this:
KERNEL=="tun", NAME="net/%k", GROUP="kvm", MODE="0660"
5. My user is part of the kvm group, although I have also tried running qemu-kvm as root.
6. In /etc/qemu-ifup I put:
#!/bin/sh
echo "Executing /etc/qemu-ifup"
echo "Bringing up $1 for bridged mode..."
sudo /sbin/ifconfig $1 0.0.0.0 promisc up
echo "Adding $1 to br0..."
sudo /usr/sbin/brctl addif br0 $1
sleep 2
7. Using visudo I added this to the bottom:
Cmnd_Alias QEMU=/sbin/ifconfig,/sbin/modprobe,/usr/sbin/brctl,/usr/bin/tunctl
%kvm ALL=NOPASSWD: QEMU
8. I launch qemu-kvm with the following script:
USERID=`whoami`
IFACE=`sudo tunctl -b -u $USERID`
qemu-kvm -net nic -net tap,ifname="$IFACE" -vga std -m 1024 -k en-us -usbdevice tablet -localtime /dev/sda
sudo tunctl -d $IFACE &> /dev/null
My system starts with br0 getting the dhcp IP on boot, so that part is working.
When I run the qemu-kvm start script I get this error (running as user or root):
/etc/qemu-ifup: could not launch network script
Could not initialize device 'tap'
/etc/qemu-ifup is executable

Denying access from hosts other than localhost
I would like to prohibit access to Directory Server from hosts other than the localhost:
I am doing this from Administration Console. On the server node I set the ACI:
(targetattr = "*")(version 3.0; acl "deny_ip"; deny (all) ip!=dirservhost_ip or ip!=127.0.0.1; )
But the access is still allowed. What is wrong?Purchase a device like this. They are offered by many cellular carriers

Hello.
in Solaris 10 i need auditing process create, delete, privilege escalation, set and change password and etc... from users account and group.
I set settings:
in file syslog.conf:
*.info;mail.none;cron.none;audit.notice @IP-Remote-syslog-server-SIEM
in file /etc/security/audit_control:
dir:/var/audit
flags:lo,ad,ex,cc,am,no,fc,fd
minfree:20
naflags:lo
plugin:name=audit_syslog.so;p_flags=lo,ad,ex,cc,am,no
in file /etc/security/audit_user:
root:lo,ad:no
Now I see in the logs only the fact of a connection via SSH and run processes on behalf of users. Creation. delete users, change passwords for some reason do not is logged.
Many users. For each individual write permissions in the file /etc/security/audit_user not possible, it is likely to forget any new user (or there is a possibility in this file one line to describe the audits for all accounts?)
Where is the mistake?You are most likely hitting Bug 15779000 user/role/groupadd/mod/del don't audit their use.
And the fix is only available in S11.2.

Not able to connect to Oracle EBS from host Windows 7
Hi, I have installed oracle EBS version 12.1.1 (32 bit) on OEL ver 6.3 (32 bit). I have installed Linux on Oracle VM virtualbox ver 4.1.16.
I am having host OS as Windows 7 home on my laptop.
While setting up the Network in Oracle VM virtualbox, I have set "attached to" as 'Host Only Adapter'.
I am able to connect to oracle EBS from the client server(linux) using Firefox browser. Both the services(database, Application) are starting & stopping without any problem.
I have entered following setting in C:\Windows\System32\drivers\etc\hosts file.
192.168.56.101 linux.server
IP address of Linux OS is 192.168.56.101
Please help in resolving the issue.
Thanks!I am getting error as "Internet Explorer cannot display the webpage" on IE ver 9, when accessing from host machine. On Firefox (ver 12), the error is coming as "The connection has timed out. The server at linux.server is taking too long to respond."
The firewall on the server has been disabled already.
I am not able to ping the server IP address or hostname.domainname from client. Following error comes while pinging -

Accessing Oracle on VirtualBox from Host Virtual Machine
Hello,
I have a Host system of windows 8, installed the Virtual Box Latest edition.
The guest OS is the oracle Linux that came with the Pre-Built Developer VMs from Oracle.
The VM is set to HOST ONLY network setting.
Now, the thing is that i want to access the Oracle in the guest machine from my windows host machine.
the guest OS shows the IP address as 192.168.56.101. I can ping the IP address from the HOST machine, but cannot connect the
SQL developer to the oracle in the guest OS from the host machine. It keeps on saying the Network adapter cannot connect.
PLEASE I need help, now please do not say that install the oracle in window itself. I actually want to do the same on my macbook pro as that is my primary machine.Hello Guys,
Thanks for the responses you provided, really appreciate that.
I made that connection and access from the host to the guest and accessing the oracle database on the guest.
System info :
Macbook Pro - OS X 10.8.4
RAM 4GB [will upgrade to 8 GB ]
VM Package : Oracle Virtual Box
VM Guest : Oracle Pre-Built Developer VM [ http://goo.gl/dtbzO ]
Network Connection : Host Only
Steps to connect Host to Guest
If you see the 'ifconfig' you will see a network adapter named 'vboxnet0' [created after the VB is installed]
Check the allocated address from the [MAC] Virtual Box -> Preferences -> Network : copy the start or in between address, which in my case was 192.168.56.101 [start one]
Assign the address to the vboxnet0 adepter by terminal : sudo ifconfig vboxnet0 alias 192.168.56.101 up
Change the VM's Network setting to 'Host Only',
Select the virtual adapter vboxnet0 from the adapter list, apply the configurations, click ok
Fire up the guest OS, and login
Check for the IP configuration there by ifconfig, you will find the eth0 adapter with the same IP as that you assigned to the vboxnet0 on host machine.
Fire sql Developer on the host machine
Make a new connection and 'Hostname' as same as the vboxnet0 ie. 192.168.56.101, fill in the other details of the Oracle connection details needed from guest
Test the Connection
Woollaaaa you are done -

How to Access DATA, Physical Flash Drive from Host machine
Hello Everyone,
First i am sorry for My English also if i post wrong place.
In HyperV, I created 3 VM machines, and i want each machines can access to Data or Flash Drive from Host machine.
THanks you so much!
Regards
VeasnaYimHi,
The Hyper-V forum is here:
http://social.technet.microsoft.com/Forums/windowsserver/en-US/home?forum=winserverhyperv
But, your question is relatively simple. You will need to use standard Windows networking to access data from the host machine. Depending on your version of Hyper-V, connecting to it via RDP from the host machine can use the RDP client's ability
to access the host drives also. -
Access another host on same subnet through Nat'd IP address
I appreciate any help in advance, I have a requirement to monitor a host's external IP address, the monitoring host (host A) initiating the request is located in the same DMZ subnet as the destination host (host B) I want to monitor, both are NAT'd to external IP addresses, I was expecting to see a request going out from host A, getting NAT'd to its respective external IP address and then coming back in through the external interface to reach the Nat'd IP address of host B. is this how NAT will be handled by the ASA or am I missing something here? thanks again.
Borman,
Its more complicated than that, consider the following scenario:
20.20.20.0/24
ASA------------------------------Internet
| (DMZ)
Switch
Host A Host B
10.1.1.10 10.1.1.100
20.20.20.20 (Nat outside address)
Basically you want to monitor your host B using its public IP address, normally your NAT configuration (in case of version 8.2 and prior) would be something like this:
nat (DMZ,outside) 20.20.20.20 10.1.1.100
nat (DMZ) 1 0.0.0.0 0.0.0.0
global (outside) 1 interface
When going from Host A to host B, two translations should occur, first is the Unstranslate from 20.20.20.20 to 10.1.1.100 (By internal process of the ASA), then once it is unstranslated, the route-lookup comes in game. Firewall notices that is on the same interface as the source of the packet so we reach our first impass. The ASA does not support same security traffic by default. So we overcome this issue with the following command:
same-security-traffic permit intra-interface
Now that is done, so we move to the next packet process, the ASA tries to check if there is any NAT translation for a packet coming from the DMZ and going to the same DMZ. As you can see there is a "nat (DMZ) 1 0.0.0.0 0.0.0.0", that tells the firewall that everything coming from the DMZ should be translated, we hit that NAT and since the outgoing interface is the same as the source interface (DMZ) there is no global command, hence you will see an error that states, No translation group found. Here is how we overcome that issue
Global (DMZ) 1 interface
This will translate requests from the DMZ interface going to that same interface to the DMZ IP address, on the server 10.1.1.100, the connection will be seeing as it came from the firewall, the packets will be sent to the firewall again, hence avoiding asymmetric routing.
If running version 8.3 or higher, the concept is the same, but the commands change a bit.
8.3
same-security-traffic permit intra-interface
object network Server_Public
host 20.20.20.20
object network Server_Private
host 10.1.1.100
object network Any
subnet 0.0.0.0 0.0.0.0
Nat (DMZ,DMZ) source dynamic Any interface destination static Server_Public Server_Private
So bottom line, configuration needed on 8.2
global (outside) 1 interface
same-security-traffic permit intra-interface
Configuration for 8.3
same-security-traffic permit intra-interface
object network Server_Public
host 20.20.20.20
object network Server_Private
host 10.1.1.100
object network Any
subnet 0.0.0.0 0.0.0.0
Nat (DMZ,DMZ) source dynamic Any interface destination static Server_Public Server_Private
Hope this helps a bit.

Moving ASM disks from Host to Host
Hello all,
should anyone have tried this or should anyone be able to point ou some sort of documentation for this issue would greatly be appreciated;
I have two hosts that have an Oracle Database resident on filesystem that is storage replicated from between to disk groups and that on the destination the control file is used to "import" the new database.
My issue would be if anyone has tired the same with ASM and if would it be possible to have a certain scenario;
Shutdown database on source,
Replicate the disks via Storage,
Scan for the disks on the destination
<Tweak the disks so that they can be imported ?>
Import the disks to the ASM Instance
Fire up the database on destination
If anyone has some usefull insight would be most apreciated.
Regards,
FranciscoHi,
at the bottom of my last post, I did point you to some whitepapers on the ASM side, identifying what needs to be done in case of an ASM diskgroup.
So yes this will work with ASM, you simply have to mirror the whole luns and this should work.
However regarding the other points:
=> Replicating via. Oracle is definitely faster than storage. Just think of it: Oracle only needs to forward the changed of a block (never the whole block) with the help of the redologs, whereas Storage mirroring always has to take the whole block (+Redologs). So this is roughly double the data needed to be transferred than Oracle. Additionally blocks which Oracle does not need to forward (like ASM header/tablespace header information). Hence if you say it is slower, this cannot physically be the case. Only exception is if your infrastructure for network is not configured the same as the storage network is (or you have an error in setup).
=> DR with Oracle Dataguard is way below 5 Minutes if you configure it correctly. If you setup ASM mirroring between both nodes and setup a cluster than you have no downtime at all.
=> For the last point look at Snapshot Standby. This is exactly what they need + it provides DR all the time.

ASA 5505 VPN can't access inside host

I can connect with the Cisco VPN client and the VPN light is on on the ASA and it shows that I'm connected. I have the correct Ip address but I cannot ping or connect to any of the internal addresses. I cannot find what I'm missing. I have the VPN bypassing the interface ACLs.

Cannot access SAPMNT hosted on NT Cluster
We need to access SAPMNT hosted on CI node name R3-FFHK-CLS01 of the
PRD NT cluster
(CI and DB node) from another SAP QAS server name SAENUS.
The SAPLOC and SAPMNT was created during SAP installation and have been
granted everyone full control permission on both CI and DB node of PRD
NT cluster and SAP QAS server.
Despite the above, when we logon to Windows 2003 on SAP QAS server name
SAENUS to access the SAPMNT hosted on CI node name R3-FFHK-CLS01 of PRD
NT cluster, we received the following error :
R3-FFHK-CLS01\sapmnt\ is not accessible. You might not have
permission to use this network resource. Contact the administrator to
find out if you have access permissions. Access is denied.
We can connect and see the shares inside
R3-FFHK-CLS01 but cannot
access
R3-FFHK-CLS01\sapmnt. Strange.
On the other hand, if we logon to Windows 2003 on either node of PRD NT
cluster we can access the SAPMNT share hosted on SAP QAS server name
SAENUS without permission problem.
Regards, Johne.We logon to the cluster with domaina\prdadm.
We logon to the QAS with domaina\qasadm.
We can access SAPMNT hosted on QAS from cluster when logged onto cluster using domaina\prdadm.
We can't access SAPMNT hosted on cluster from QAS when logged onto QAS using domaina\qasadm.
Both SAPMNT has been granted everyone full control permission. -
Access application hosted on a different machine.
Hi,
I've written a simple web application to select an excel file through a jsp and write it's contents to text file. I select the execl file by browsing through the folders in my system. when i submit the form giving the location of the text file to which this excel file contents have to be written i'm getting the expected result. This application is hosted in Tomcat in my system. But when i tried accessing the application from another system my application is unable to find the excel file path selected in that machine. So i'm getting FileNotFoundException. Please suggest a solution.
Thanks,
SudhaHi,
I know that an application is hosted on a particular system. That application's job is to take the excel file selected by me and create a text file out of that. But as that application is hosted in a different machine it is unable to find the path i select. My doubt is like is it possible to have an application like this with actual source code and server on one system and user accessing from a different system and still able to find the path of the excel file the user is selecting?
Thanks,

Issue in accessing service hosted on a different network
We have a wsdl hosted on ebiz apps server which is accessed from one of our bpel processes which run on a soa server. Now both these servers (ebiz apps and soa) are on a different network, so I need to give IP address of my ebiz apps server while deploying bpel on soa server. This works fine and bpel on soa server is able to access my wsdl on ebiz apps server. (e.g. instead of ap6039fems:7785, I give 144.20.199.84:7785)
Now, my ebiz wsdl in turn imports some xsds using the ebiz server host name; these I cannot replace with IP address since I cannot modify the ebiz wsdl contents. This leads to issues during deployment on soa server since the compiler on soa server cannot access the xsds hosted on ebiz server. Do you know of any way to overcome this network issue, any dns entry would help ! Could you please share your experiences if any or point to someone.I
