  • Multiple INET sockets (mulple IP's too) connected to UNIX sockets

    - by Andrew
    HOST = same host all the time, accepts multiple connection. I have a dedicated server and I will buy extra IP's. Socket 1 connects to HOST:PORT, from IP-1 Socket 2 connects to HOST:PORT, from IP-1 Socket 3 connects to HOST:PORT, from IP-1 Socket 4 connects to HOST:PORT, from IP-2 Socket 5 connects to HOST:PORT, from IP-2 Socket 6 connects to HOST:PORT, from IP-2 After creating all sockets I want to access them easy as UNIX sockets from PHP. /sys/socket1 /sys/socket2 /sys/socket3 /sys/socket4 /sys/socket5 /sys/socket6 I want the sockets to work in background (like daemon) and I want to be able to connect from PHP to any of this sockets and RECV/SEND whatever I want. I saw "socat" and I think that's the solution for me, please tell me how to use socat, or how to do it other way. Thankyou!

  • How do you get the IP addresses of KVM guests that are using a Bridge Network Device from the KVM host

    - by slm
    Does anyone know of a way using KVM to find out the IP addresses of KVM guests that are using a bridge interface (br0) through the KVM host? Currently I have br0 setup with a single NIC (eth0) included. The KVM host is a system running CentOS 5.6 in case that matters. The guests are also running CentOS 5.6. BTW, the guests do not just show up in the KVM host's arp table, I'm looking for better solutions and/or leads.

  • Replace an IP address with it's whois using bash

    - by user2099762
    I have a traffic log similar to this "page visited" for xxx.xxx.xxx.xxx at 2013-10-30 and I would like to replace the ip address with the result of it's whois lookup. I can export the ip addresses to a separate file and then do a whois on each line, but im struggling to combine them all together. Ideally i'd like to replace the ip address in the same string and print the new string to a new file. So it would look like "page visited" for example.com at 2013-10-30 Can anyone help Here's what I have so far grep -o '[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}\.[0-9]\{1,3\}' clean_cites.txt > iplist.txt for i in `cat iplist.txt` do OUTPUT=$(geoiplookup -f /usr/share/GeoIP/GeoIPOrg.dat $i) echo $i,$OUTPUT >> visited.txt done Like I said,this produces a separate file with a list of ip addresses and their relevant hostnames, so I either need to search for the ip address in file and and replace it with the text in file b (which will give the ip address and hostname) or replace the ip address in place. Thanks

  • Adding many IP addresses to Windows Firewall using CLI fails partially

    - by Thomas
    I have a PowerShell script which adds IP addresses to Windows Firewall using the "netsh advfirewall" command. (As described in this question: How to append netsh firewall rules, not just replace). The problem is that when adding a lot of IP addresses (currently over 700) the string of IP addresses seems to be 'cut off' at some point. Only an X amount of the total amount of IP addresses are actually added to the firewall, the rest... not. The script is very simple, and looks something like this: $ip = "123.123.123.123,124.124.124.124,125.125.125.125 and so on" netsh advfirewall firewall set rule name="*" new remoteip="$ip" I tried to echo the string to see if it's cut off; echo $ip But the complete string is correctly echo'ed. Is there some kind of string length limit for the netsh command? Or anything else that could be causing this issue?

  • Why is my amazon EC2 in asian pacific region having a US ip address?

    - by Turner
    I recently give a free trial to amazon EC2 service, I created a free tier micro instance(AMI is windows server 2008) in the Asian Pacific(Tokyo) region, but when it's done the public DNS it provided is ec2-54-238-181-35.ap-northeast-1.compute.amazonaws.com. The corresponding IP is 54.238.181.35, which I think is in the U.S. I tried to allocate some more elastic IPs but all of them seem to have a U.S. origin. Anyone please help explain to me ?

  • Puppet nodes cant' find master, ec2 public versus internal ip addresses and hosts files

    - by Blankman
    If I setup my hosts files such that they reference all other ec2 nodes using the internal ip addresses, will this work or do I have to use the external ip addresses? Do I need to specify anything in my security group to get internal ip addresses to work? e.g. /etc/hosts ip-10-11-12-13.internal some_node_name If I do this, can I reference some_node_name anywhere in my scripts where I would have used the ip address previously? On my puppet agent servers, I have a reference to my puppet master like: public-ip-here puppet When I reboot my puppet agent's, syslog shows they couldn't find the master with the message: getaddinfo : name or service not known I did get it to work by updating /etc/default/puppet and I added to the options: --server=public-ip-here From what I read, puppet will by default try using 'puppet', and I set this in my hosts file so why wouldn't it be picking this up?

  • What can I use to monitor which IP address w/name resolution is connected to each PID?

    - by supercheetah
    This would be for under Linux particularly. Is there a tool out there, or a script that I could use to monitor IP connections--with name resolution--and, see which process they're connected to? Right now I'm using this: watch -d netstat -peeW --numeric-hosts --inet But that doesn't give me host resolution. I was thinking of writing up a script with sed or something, but that seemed like more work than it needed to be.

  • Good Documentation on Avaya IP Office 500 r2 setup

    - by Cliff Racer
    I have set up a couple of Avaya IP Office systems over the course of my current job. I have a pretty good handle on the process, but now I am faced with something I have not done before. Both the IP office systems I have set up used all Digital phones. The new system we are putting in place will actually use IP phones for the first time. After tyring to track down some general documentation on my own, I was not able to find anything that left me feeling comfortable about setting up IP phones on an Avaya IP Office 500. Does anyone know of any good how-To's for setting up IP phones on IP Office? I get the impression its pretty simple but learend enough about Avaya to know that there are some tricky aspects to setting them up

  • Changing Servers - Redirect to new IP = No Downtime?

    - by Denis Pshenov
    I am changing servers of my website. The IP of old server cannot be moved to the new one. To have no downtime I am planing to do the following, please someone confirm it will work: Setup the new server and listen on the new IP Old server redirect all traffic to the new IP Change DNS records to point to the new IP My logic tells me that when I redirect to the new IP from my old box, the user will not see the domain name in the browser but will see the new IP. Is there a way to redirect to the new IP and send along the HOSTNAME with it so that the user will see the domain name in the browser? Im doing this because the site is in constant use and simply changing DNS settings won't do as database won't be synced between the new and old servers during propagation.

  • One bigger Virtual Machine distributed across many Nodes [on hold]

    - by flyer
    I just setup virtual machines on one hardware with Vagrant (this is just a test environment, not production!). I want to use a Puppet to configure them and next try to setup OpenStack. I am not sure If I am understanding how this should look at the end. Is it possible to have below architecture with OpenStack after all where I will run one Virtual Machine with Linux? ------------------------------- | VM | ------------------------------- | NOVA | NOVA | NOVA | ------------------------------- | OpenStack | ------------------------------- | Node | Node | Node | ------------------------------- (In my environment Nodes are just virtual machines, but my question concerns separate Hardware nodes) After some comments... Is it a language barrier, or? This is only my 'virtual environment'. If we imagine this virtual machines are a separate Nodes (e.g. every has 4 cores) the OpenStack is still the same, right? Can I run one Virtual Machine across many Nodes with OpenStack? Is it possible to aggregate the computation power of separate machines in one virtual distributed operating system?

  • Preventing - Large Number of Failed Login Attempts from IP

  • Replacing old server with new but different hostname & same IP

    - by MaxFr
    We have an old server 2000 and lots of users point to it by hostname and by its IP e.g \\server1, we have a new server 2008 R2 with new name serverlocation1 All folders and data have been sync'toy'd from the old server1 across to serverlocation1 each evening, the new server tree is exactly the same on the new server and all perms are correct. We need to make the new server the same IP as the old server1 as too many people access it directly via IP, and to ensure file and folder paths stay ok, anything \\server1\folder\file needs to go to \\newserverlocation1\folder\file etc I can change the old server1 name to server1-old & change IP and assign the old IP to the new server, but how do I force anything coming in for \\server1 to go to the new server and ensure anything referenced to the old server goes onto the new server ? I can CNAME but I need the new server to have the IP of the previous server so not sure if its straight forward etc..... point server1 to newserverlocation1 Then probably change DNS so that the OLD IP points to new hostname..... Any clarification appreciated.

  • How do I set up domain names for IP's on my LAN?

    - by Qemal Stafa
    I have a LAN with 50 clients and my company has made me do a local WebApp. This is new territory for me, but as I see it, the individual internal IP's are regulated by MikroTIK. I was wondering, how does one make MikroTIK recognise internal domain names for this IPs? Right now, the WebApp works fine and can be used by entering 192.168.3.150/app/ But since most people have difficulties entering IPs I was wondering if i could do smth like : myroom.lan would be just as you typed 192.168.3.150

  • Route using certain IP address

    - by spa
    I have a server with two public IPs. Both IPs are added to eth0 using ip addr add. Now I'd like to contact a server which uses IP address filtering. Only requests are allowed which use the second IP address. Is there are way to set this up using the standard route command in Linux? I guess that's not the case. So the only solution I see right now: Setup a virtual device let's say eth0:0 and bind the second IP address to it. Then I can reference the device in the route command. Edit: I can't use the second IP as primary one easily as this IP is used as failover IP.

  • Converted VmWare Image does not boot in Virtual Box

    - by vBox Question
    I have a .vddx virtual image which boots in VmWare, but I'm having trouble getting it to work with Sun Virtual Box. In Sun Virtual Box, I created a new Virtual Machine and pointed it at the vddx file from VmWare. When I try to boot the virtual machine, Sun Virtual Box says that the volume is not bootable. VmWare is able to boot from this virtual machine. Does anyone have any suggestions about what might be causing the problem? Is there a conversion utility that I need to run? Any debugging options that I could turn on?

  • Why am I getting cgi-sys/defaultwebpage.cgi coming up when I browse my webpage?

    - by CraigJ
    I've recently set up a website with a smaller hosting company. The plan has a dedicated IP. They sent me emails to say it's all set up, but now their support channels are all unresponsive even though they say it's open 24 hours. In the File Manager in the cpanel I've put an index.html file in the public_html directory. But when I point my browser to the IP address given to me, it comes up with the cgi-sys/defaultwebpage.cgi page. What is the problem? I haven't set the name-servers for my domain yet, but that shouldn't be a problem because I am using the IP address in the browser. Note: I don't think I have access to ssh.
