I followed RDO:neutron-with-existing-external to install an openstack env on VirtualBox Instance(CentOS7). After that, I logged into openstack and created an cirros instance to check connectivity with external network. Then, weird thing happened.
PING PASS (with floating IP address):
1. VirtualBox instance (where installed openstack) <-> Cirros Instance
2. My laptop <-> VirtualBox Instance
PING FAIL:
1. My laptop cannot ping the Cirros Instance
2. The cirros Instance cannot ping my laptop
3. The cirros Instance cannot ping external gateway
Is there anybody can give me some suggestions or guide?
Thanks in advance,
Eventually, I find the answer by myself. The root cause is my PROMISC mode is not enabled. I wrote a note for this issue. ([RDO Stack:VMs cannot access external network.1)

I use CentOS 7 with Apache server. The problem who command does not show clients connected with WinSCP. Can't understand why.
The problem who command does not show clients connected with WinSCP. Can't understand why.
Apparently, then, you are operating from a false premise. The who command does not promise to name everyone interacting with the system in any way whatever. Roughly speaking, who tells you about users who have an associated terminal, whether physical or virtual. Connecting via an scp client does not establish a login session or allocate a terminal for who to report on.
Contrast users who connect via ssh clients: these do get a terminal assigned to them, and they do show up in the output of a suitably-timed who command.

The scene is under VMWare, and the os in vm is Ubuntu 12.
What I have to say is the network was actually suddenly cut off when I was coding. My two colleagues were all have the problem. It seems very odd. It just is a vm dev environment. Why three person will occur it in a not long time periods. I couldn't ping the IP in VM from my host, and vice versa.
At the first time, I think it is the problem of network adapter of VMware. But it didn't work after I removed the network adapter and re-added it.
But this time, I think ping it. But the network is very slow. I just ping a IP, not a domain.
So, when I used wireshark to see what is the problem.
As the picture show below. I think it is a virus. The random string before <00>.
Anyone can give me the solution or some hints? Thanks!!
Perhaps it's a virus called Chrome, from a company called "Google"; Chrome appears to make various weird name queries.

I have recently added a dlink router to my existing network, and connected some computers with it. The existing network uses ip range 192.168.1.x and the new router uses 192.168.0.x. Internet services is accessible on both the networks, but a shared resource or a web server connected to one network is not accessible to the systems of other network.
I googled this issue but I am unable to resolve the issue, please help.
If you are just going to be using the router as a switch on an existing network, you need to turn off its router-y features.
Go onto the web interface of the device and turn of "NAT", that way they'll use the same address space as everything else on the network.
They'll be other features as well you may want to turn off but that's one causing your current issue.

I'm working with SVN server to develop SW.
I have nothing but single dummy hub(5 port).
What I want to do is sharing source FILE on the SVN server so that all developers can work together.
please check my plan to do this...
Allocating IP address to all client...
client1 : 172.20.20.11
client2 : 172.20.20.12
client3 : 172.20.20.13
client4 : 172.20.20.14
SVN server : 172.20.20.100
GW : 172.20.20.1
NETMASK : 255.255.255.0
I'm not sure for the GW ans NETMASK config....
Is this possible?
Netmask is fine, or you could use 255.255.0.0 (and a few others; doesn't matter so long as every machine has the same configuration).
Gateway doesn't matter since you don't have internet access anyhow, set it to 172.20.20.whatever.

I use Cisco secure mobility client to connect to my office VPN. After I connect to VPN all my requests go through the office gateway and my access to internet through my locally installed router (connected wirelessly) is blocked/not reachable. How do i rectify this?
I've searched on the web and stack overflow, and they suggest split tunneling which I think is not an option here as I cant change the Cisco settings. Is there any work around for this? I've tried adding router address to the IP table , but that isn't helping.
My OS is windows 7.
Please let me know if you need any other information.
Mike is right, this is off-topic but I can tell you that unless the Cisco VPN administrator allows split-tunneling then there's no work-around for this. The best solution I can tell you, is to make a VirtualBox VM with your OS of choice and use that VM to connect to the VPN, thereby leaving your host machine free to browse the internet locally.
