  • OpenDNS IP Conflict

    - by Paddy
    I have downloaded the OpenDNS client and it was working great till today. Shows me this error: dynamic IP update failed with message !yours or "Your IP address is taken by another user." I am pretty sure i'll get away with the problem by just restarting my connection as i'll be assigned a new dynamic ip. But I wonder how this is happening in the first place. Shouldn't Dynamic IP be unique for everyone?

  • How to get a static ip address on adsl

    - by user23950
    I tried it before by setting the ip address manually. And I used this IP Address: 192.168.1.33 I reboot and tried if I can connect to the internet, but no luck. It must be set to obtain your ip address automatically. Is there any way on getting a static ip address on an adsl/dsl

  • New IP address with TSOCKS

    - by Matthew Downey
    I am using tsocks on my Ubuntu machine and I have it all set up so that if I run wget -q -O - checkip.dyndns.org|sed -e 's/.*Current IP Address: //' -e 's/<.*$//' in my normal shell I get my real IP address, and if I run tsocks wget -q -O - checkip.dyndns.org|sed -e 's/.*Current IP Address: //' -e 's/<.*$//' I get another IP address like I should. My question is how do I make the tsocks command return with a different 'different address'; in other words establish a new identity.

  • Multiple IP stacks

    - by Aditya Sehgal
    I have a linux box with two ethernet interfaces (eth0 & eth1) with two corresponding IPs. As per my understanding, currently they are served by 1 IP stack. Is it possible to install another IP stack with IP Stack 1 handling ethernet interface eth0 and the other IP stack handling eth1.

  • Redirect all outgoing traffic on port 80 to a different IP on the same server

    - by Spacedust
    I have multiple IP addresses on the same server and I would like to redirect all outgoing traffic on port 80 to a different IP on the same server just no to use always main IP. Currently I'm using this: /sbin/iptables -t nat -A POSTROUTING -o eth0 -j SNAT --to-source IP; and it works well, but it redirects everything and when I make backups over SSH backup it's failing. System: CentOS 5.8 64-bit

  • Assign a secondary IP address to a Windows machine using DHCP

    - by IndigoFire
    Is it possible to configure dhcpd (on a Linux box) to assign a Windows PC 2 separate IP configurations? Right now I've configured the two IP addresses manually and it does exactly what's needed, but I can't figure out how to achieve the same thing with DHCP. For example, is it possible to set up a virtual interface that piggy-backs onto the first interface and gets its own configuration? Alternatively, is it possible to run a script upon getting IP values from DHCP that would then be able to configure the secondary IP?

  • question about IP address

    - by baddogai
    i know how IP basically works, and knows that an IP address composed of a network ID portion and a host ID portion, but when I type a IP address ,say "8.8.8.8" into the web browser, i DIDN'T supply any subnet mask information, so how does the browser know where the dividing line is between the network ID and host ID? since 8.8.8.8 may mean 8.8.8.8/8, 8.8.8.8/24 etc. In a nutshell, the IP address I supplied is ambiguous.

  • How to find the real IP to which IPVS is routing a virtual IP

    - by Wayne Conrad
    I'm trying to find a problem server hiding behind a virtual IP (using LVS/ipvs). I've got a test program that sends requests to the virtual IP until it gets the bad response, but how can I tell to which real IP a request to the virtual IP got routed? On the box doing the virtual IP magic, here's the virtual IP configuration (for the service I care about): IP Virtual Server version 1.2.1 (size=4096) Prot LocalAddress:Port Scheduler Flags -> RemoteAddress:Port Forward Weight ActiveConn InActConn ... TCP 10.1.0.254:5025 nq -> 10.1.0.5:5025 Route 1 0 1 -> 10.1.0.6:5025 Route 1 0 5 -> 10.1.0.7:5025 Route 1 0 2 -> 10.1.0.9:5025 Local 1 0 3 -> 10.1.0.11:5025 Route 1 0 3 ... My client program is sending TCP requests to 10.1.0.254:5025, usually getting a good response but sometimes a bad response. With this few servers, I could send my request to each server in turn until I discover the culprit, but I wonder if that technique will scale as we add servers. What means exist for me to find out where requests got routed? Kernel: Linux 2.6.32 OS: Debian testing (whatever that's called these days). ipvsadm is version 1.25, compiled with ipvs v1.2.1

  • IP to IP forwarding with iptables [centos]

    - by FunkyChicken
    I have 2 servers. Server 1 with ip 1.1.1.1 and server 2 with ip 2.2.2.2 My domain example.com points to 1.1.1.1 at the moment, but very soon I'm going to switch to ip 2.2.2.2. I have already setup a low TTL for domain example.com, but some people will still hit the old ip a after I change the ip address of the domain. Now both machines run centos 5.8 with iptables and nginx as a webserver. I want to forward all traffic that still hits server 1.1.1.1 to 2.2.2.2 so there won't be any downtime. Now I found this tutorial: http://www.debuntu.org/how-to-redirecting-network-traffic-a-new-ip-using-iptables but I cannot seem to get it working. I have enabled ip forwarding: echo "1" > /proc/sys/net/ipv4/ip_forward After that I ran these 2 commands: /sbin/iptables -t nat -A PREROUTING -s 1.1.1.1 -p tcp --dport 80 -j DNAT --to-destination 2.2.2.2:80 /sbin/iptables -t nat -A POSTROUTING -j MASQUERADE But when I load http://1.1.1.1 in my browser, I still get the pages hosted on 1.1.1.1 and not the content from 2.2.2.2. What am I doing wrong?

  • Windows Server: specifying the default IP address when NIC has multiple addresses

    - by Cédric Boivin
    I have a Windows Server which has ~10 IP addresses statically bound. The problem is I don't know how to specify the default IP address. Sometimes when I assign a new address to the NIC, the default IP address changes with the last IP entered in the advanced IP configuration on the NIC. This has the effect (since I use NAT) that the outgoing public IP changes too. Even though this problem is currently on Windows Server 2008, I've had the same problem with a Windows Server 2003. How can you set the default IP address on a NIC when it has multiple IP addresses bound? I remark something. When i check route print i see is it there the problem ? 0.0.0.0 0.0.0.0 192.168.x.x 192.168.99.49 261 if i want the default ip be example : 192.168.99.100 There is my route.

  • How can I set up multiple dynamic users to update a single network's dynamic IP

    - by d3vid
    On my home network we are allocated a dynamic IP. I want to configure ddclient (or an equivalent) to send IP updates to DNS-O-Matic/OpenDNS only when I am on my home network. I do not want to send IP updates when I'm on my office network. Can this be done? I am prepared to use different FLOSS software or a different free DNS service. Additionally, there are multiple users who may be on the home network or away on other networks. How can we configure ddclient on each machine so that whoever is on the home network updates the IP (i.e. so we don't have to rely on a particular machine being on the network to update the IP). OpenDNS support have said we can't simply install updater software on each machine.

  • Public IP Routing over Private GRE tunnel

    - by Paul
    I have a GRE tunnel configured between two linux boxes. The tunnel works fine. I can ping from each host the other private ip. Head privateip: 10.0.0.1 publicip: 8.8.8.8 Tail privateip: 10.0.0.2 publicip: 7.7.7.7 The public IP on Tail has the network block 9.9.9.0/23 statically routed over the 7.7.7.7 interface. The idea is to make the 9.9.9.0/23 ips work on servers on the 8.8.8.8 network. I configure the tail host to route the /23 block. I mounted a 9.9 IP on the head server. I can ping the 9.9 ip from the tail to the head. I can't ping the 9.9 ip from the public internet. I think I need to add some other routes because of gateway issues, but I can't seem to wrap my mind around it (not a router guy, just beating my way through something that I have never done before and vaguely understand) --danks

  • Is it possible to rent an IP address to mask the server real IP address?

    - by net-girl
    A customer would like to lease an IP address and point it to a dedicated web server with the intention of "masking" the server's IP address so it would be difficult to tell where the site is hosted. I found a company that leases IP addresses here: http://www.webhostingtalk.com/showthread.php?t=1191688 Is this even possible? Can they rent an IP address from a 3rd party in order to hide the server's IP address? Update: My client will be hosting a government leaks site and is trying to become Raid-Proof similar to what the pirate bay did: http://torrentfreak.com/pirate-bay-moves-to-the-cloud-becomes-raid-proof-121017/ Only that I'm worried about using a reverse proxy because of the latency it could cause having the app servers hosted in one data center and the load balancer/reverse proxy in other and also having to pay twice for bandwidth.

  • Using QoS to prioritize IP addresses

    - by Tristan
    I have a Western Digital N900 router. I was hoping I'd be able to throttle users based on their MAC address with it, which isn't possible sadly. Seems simple in principle though, duh. The battle against bandwidth hogging roomates rages on. Could I just set the local IP range to their IP, and then set the Local port range to every single port in existence. Then prioritize their IP to lower than mine? Will this work? What are all the ports? And what's the difference between Local and Remote IPs or Ports? Name: Roomate, Priority: Low, Protocol: TCP or UDP ??, Local IP Range: .101 to .101, Local Port Range: 0 to infinity, Remote IP Range: ? to ?, Remote Port Range: ? to ?

  • an unknown ip on network

    - by Ahmed safan
    In our office we have many PCs, all of them have static IP addresses. We had a problem with one server with ip 192.168.1.10 dropping off the network occasionally. I unplugged the network cable from the server and from pinged 192.168.1.10 from another host and there was a response. I searched all PCs to see if any has such ip but i didn't found a one. I changed the server ip to fix the problem, but I still find this rogue device using 192.168.1.10 on the network -- how can I figure out what it is? Could it be the ip of virtual machine on someone's PC?

  • Plesk 10 Postfix with multiple IP adresses and SSL certificates

    - by JulianB
    We are currently running a root server with Debian 6 and Plesk 10.4.4. We have some virtual hosts using one IP adress (shared) - e.g. example1.com - and another virtual host using a dedicated IP address (example2.com). Is there a way to configure postfix to do the following Always use the IP address of the virtual host to which the e-mail account belongs (so that an e-mail from [email protected] will originate from the shared IP-Address and an e-mail from [email protected] will originate from the dedicated IP? Use different certificates for TLS for example1.com and example2.com? If the latter is not possible: Could any problems arrive when using example1.com as certificate for example2.com users? Of course, example2.com users would have to configure their clients to use example1.com as the SMTP server name to avoid annoying security warnings. But if we still would be able to get the effect of the first point that would still be acceptable.

  • Why my public ip address is different when I visit different website? [closed]

    - by Mett Li
    After I connect to web via pppoe, I visit different website's phpinfo() page, but the result of _SERVER["REMOTE_PORT"] is different. Including some ip address lookup site like www.whatismyip.com, www.apnic.net etc. and gmail's ip location lookup list are all different. Why? Is these different ip address allocated by ISP on different web resources ? Maybe the reason is CDN by my ISP or the website? If the reason is the ip address allocated by ISP on different web resources, the website visitor's ip address may unreal.

    I recently opened a dynamic dns user (at no-ip for that matter..) for my own personal needs and especially for ssh-ing my computer whenever I need to, without knowing it's static IP. My questions are: Am I misusing the concept of dynamic dns? Are there more appropriate methods to do what I want to do? If not, how do I resolve my router's real ip address? Firefox somehow manages to do so, nslookup and other similar commands only resolve the ip of the ddns server (e.g. no-ip.org). Trying to figure this mystery with wireshark failed miserably ;)

  • how to setup sonicwall tz210 to port forward packets received from external ip to another external ip

    - by lplp
    i have a sonicwall tz210 on a fixed ip, say ip1. And then i have, let's say a legacy server, with external ip ip2, which sends data to ip1 (and I have another server on ip1 behind the sonicwall which receives and processes that data). I would like to set up a new server on a different external ip ip3 that will receive and process data from the legacy server. How can I setup the sonicwall so that the packets received from the legacy server (from an external ip) are port forwarded to the external ip address ip3?

  • How to set IP address of Amazon EC2 instance to its Elastic IP?

    - by TWord
    Hi, I have an Amazon EC2 instance running and I am installing a program on it that needs to know what the machine's IP address is. Can I set the Elastic IP address to the IP address within the EC2 instance? Its okay if it reroutes data packets somewhere 'outside' and then back to itself, but the software NEEDs me to specify an IP address of the machine its on. I proceeded with the software installation using the "local IP" (10.xx.xx.xx) within the software installation. I don't know if this is the reason why the application is not visible publicly (as I'm trying to determine in the question http://serverfault.com/questions/166946/allowing-web-access-to-an-amazon-ec2-windows-server-2008-instance-running-tomcat)
