Are you allowed to use the same vswitch for 2 separate HPVMs?
Can you use the same vswitch for multiple HPVMs?
The reason I ask is because I created a vswitch and assigned it to one hpvm, and I was able to get it on the network. Then I created a second hpvm and used the same vswitch, and I am able to ssh/sftp TO the second hpvm, but I am unable to ping OUT of the second hpvm. I am unable to ping the default gateway or any other IP address (including the DNS server) and nslookup fails.
The two hpvms are on the same subnet as my host machine, all 10.25.112.x. I thought maybe I have to create a new vswitch, so I did this:
It says Lan in use so I am assuming I cannot have the same lan0 device assigned to two separate vswitches?

Hello,
Could someone explain why rlogin is allways allowed in my AIX 6.1 boxes, whatever user I use ?
According to documentation it should work only when .rhosts (or hosts.equiv) is properly set. But even these files do not exist - access is allowed.
If I use rsh(with specified command) it... (2 Replies)
Hi guys!
I'm working on a little script. I have a txtfile with several hosts, Unix team has copied my keys into several of those servers, but not all of them, I need to figure out which ones I don't have access to, (I want a list of servers I don't have access to, so I can request for it). This... (1 Reply)
I have this script. (options is an array) It works fine. It responds fine to all items that are stored in the array. But when I press spacebar when I am asked for input. It will not give an error only run the function again. While I put : || ] in the script to capture the space. What am I missing... (6 Replies)
hi guys,
Why is subclassing not allowed for many of the SWT Controls?
But Eclipse itself creates our Shell classes in this way (inheriting from Shell) and then overriding checkSubclass() with empty body. So is it good(safe) that we do this way? I have two shells (Shell_1, Shell_2). Shell_1 is... (0 Replies)

Hi,
I tried to post some perl code for discussion (wrapped in swaddling . However, a regex has an escaped backslash so the forum parser sees it as an URL?

Want to run this by you all before opening a PMR with IBM Support.
It's been a few weeks since I have done this so I can't be 100% sure of how I think it worked in the previous version.
We upgraded our HMC's yesterday to 7.7.9 SP2 in hopes of fixing some issues we were having. Today I needed... (4 Replies)

veth(4) Linux Programmer's Manual veth(4)NAME
veth - Virtual Ethernet Device
DESCRIPTION
The veth devices are virtual Ethernet devices. They can act as tunnels between network namespaces to create a bridge to a physical network
device in another namespace, but can also be used as standalone network devices.
veth devices are always created in interconnected pairs. A pair can be created using the command:
# ip link add <p1-name> type veth peer name <p2-name>
In the above, p1-name and p2-name are the names assigned to the two connected end points.
Packets transmitted on one device in the pair are immediately received on the other device. When either devices is down the link state of
the pair is down.
veth device pairs are useful for combining the network facilities of the kernel together in interesting ways. A particularly interesting
use case is to place one end of a veth pair in one network namespace and the other end in another network namespace, thus allowing communi-
cation between network namespaces. To do this, one first creates the veth device as above and then moves one side of the pair to the other
namespace:
# ip link set <p2-name> netns <p2-namespace>
ethtool(8) can be used to find the peer of a veth network interface, using commands something like:
# ip link add ve_A type veth peer name ve_B # Create veth pair
# ethtool -S ve_A # Discover interface index of peer
NIC statistics:
peer_ifindex: 16
# ip link | grep '^16:' # Look up interface
16: ve_B@ve_A: <BROADCAST,MULTICAST,M-DOWN> mtu 1500 qdisc ...
