I want to know is there a way to get information about the pool ip addresses that i have in my openstack ?
i use Havana as version and neutron as network service in a seperate machine
Thank you
Don't know what information you're looking for, but I suggest looking in this post here: How to check number of floating IPs available in a pool?
If that's not the information you're looking for I would still look for other arguments for openstack floating ip command

I'm new here and to all of this stuff but there is a question on my mind for a long time that I didn't find an answer to it. My question is, is there any possible way for someone to get my or someone's else IP address if they are both connected to the same server? For example, let's say that person A and person B are playing a video game that uses dedicated servers, is there any possible way of person A to get the IP address of person B? I know that they can get the IP address of the server that they are connected to it but is there a way for some of them to get even more information and get the IP address of the other client that is connected to the same server?
As I said I'm still a newbie to all this networking stuff so any info would be appreciated!
Thanks!
It all depends on how the application is built, if its only communicating to the server and its not passing the IP to the other clients then its not possible. If the Application have a peer-2-peer functionality you should be able to do "netstat -a" in CMD and see the IP of the other client. Alternative you need to access the server itself.
Not without having the administrative access to the server itself (or if application that they both use, offers this information - but this is rare currently).
Comcast installed a Juniper Universal Access Router ACX1100, I plugged our switch to the port that the technician told us that is in/out port. But nothing happened, after reading and asking I was told that I need a managed switch to be configured with the gateway IP and that IP is a /29. That's where I got lost. According to him there are 6 usable IP's.
example:
Gateway: 192.168.120.161/29
Usable Range: 192.168.120.162 - 192.168.120.167
One of my multiple questions is what hardware do I need to be able to connect my PC's?, I configured a managed switch, but when I connect my laptop to it I get Unidentified Network and No Internet Connection.
I have been reading and I think I need a VPN with DHCP server integrated.
If some one can help me I'll appreciate it.
/29 is the subnet mask, it can also be expressed as 255.255.255.248. Basically it defines which part of the IP is the network ID and which part of IP is the host ID.
I think in order to accurate assess your situation, we need to know exactly what kind of configuration you set on the managed switch you purchased, also which managed switch did you purchase?
Also currently on your laptop's NIC, what IP is assigned on there?
Either on your old unmanaged switch or on the managed switch, you can try assigning one of the addresses from the /29 block that the technician told you about statically. And the default-gateway with the addresses you posted in your question.
I have a unix machine on a network and I'm looking to get the device hostname for devices on that network. How do I go about doing this? I've tried nmap, arpscan, host, and nslookup but they all seem to want to do a DNS reverse lookup. I don't have a DNS server on the network.
When I say hostname I'm referring to the device name set by the user. So for example host on my machine returns joshcloud.
I'll give you the same answer I gave here: How to get hostname from IP(Linux)?. Basically you're going to need to either add DNS entries or connect to each host individually and ask for names.
nbtscan for Windows devices. avahi for things that suppor zeroconf.
Otherwise check out the other answer.
I am running a series of tasks using Celery and RabbitMQ which quickly reaches the rate limits of websites the tasks request from. I was wondering if it's possible to bind an instance of celeryd to an public IP address and have multiple instances running on the same machine?
I do have multiple public IP addresses I can use but I have very little experience with networking.
Thanks in advance for any help!
Yes, you should be able to do what you want to do by running several celeryd instances and binding each to an IP using a shim. See here.
Another option would be to just assign the additional IPs to your network card using ifconfig and let the OS send the traffic over whatever IP it chooses to. According to this you should get a distribution of traffic across the different IPs. Downside: no control which IP is used by which process.
Hope that helps
I'm currently revising for an exam and I'm stuck on a question which is:
"Explain the static and dynamic host configuration approaches."
I'm unsure if the answer is correct but what I've write is this:
static host configuration are hard-coded addresses that will only work on one specific network segment, which is intended for stationary computers
dynamic host configurations work best with portable computers like laptops that move between network segments.
that's my answer, could anyone help me to understand if this is correct or not?
You are correct about the difference. But there s a lot more than what you have stated.
DHC : Used to configure IP addresses automatically to the systems without any intervention of network administrator.
For Eg. When you register for a new internet connection, your ISP(network administrator, in this case) will provide you access to the DHCP server which ll allot you the IP address on the runtime.
To prevent the same IP address being assigned to two different computers
Also the main use is, ISP s will have a range of IP addresses with them. You ll be assigned any of their IPs dynamically by DHCP Server when your lease time expires for a particular IP that have been assigned earlier
SHC : Used to manually configure the IP addresses to systems.
When you knew how many systems are going to be present exactly inside the network
And when you want to uniquely identify a system in the ntwk using its IP address
For Eg. When you configure LAN in your house, between, say, around 4 computers. You will know exactly the number of systems in the group. So you don't have to allot a DHCP Server to allot the IP addresses for these 4 systems. YOu manually configure them
Hope that helps :)
