  • Fixed and dynamic IPs in ISC DHPD lead to double lease

    - by GorillaPatch
    I would like to have a small dynamic adress part and the most clients are assigned a fixed IP adress. My dhcpd.conf looks like this: use-host-decl-names on; authoritative; allow client-updates; ddns-updates on; # Einstellungen fuer DHCP leases default-lease-time 3600; max-lease-time 86400; lease-file-name "/var/lib/dhcpd/dhcpd.leases"; subnet 192.168.11.0 netmask 255.255.255.0 { ddns-updates on; pool { # IP range which will be assigned statically range 192.168.11.1 192.168.11.240; deny all clients; } pool { # small dynamic range range 192.168.11.241 192.168.11.254; # used for temporary devices } } group { host pc1 { hardware ethernet xx:xx:xx:xx:xx:xx; fixed-address 192.168.11.11; } } The motivation for the pool declaration with deny all hosts comes from the ISC DHCPD homepage http://www.isc.org/files/auth.html This will allow hosts to be first added to the network, where they will receive a temporary IP from the 241-254 adress range and then later write an explicit host declaration. Upon next connect it will receive the right configuration. The problem is that I am getting error messages that 192.168.11.13 has a dynamic and a static lease. I am a bit confused as I expected the pool declaration with deny all clients would not count as dynamic. Dynamic and static leases present for 192.168.11.13. Remove host declaration pc1 or remove 192.168.11.13 from the dynamic address pool for 192.168.11.0/24 Is there a way to have the DHCP server send an DHCPNA to clients if they have a host statement and retain this dynamic range?

  • Connection two wireless ADSL routers to share IPs

    - by user35218
    I have two wireless ADSL routers sitting right next to each other, each with his own internet connection. I'd like to be able to connect to a computer that is connected to router A from a computer that is connected to router B, while keeping both routers internet connection individually. i.e. If computer A is connected to router A, it will use router A internet connection, and a second computer, call it B, will be connected to router B, and will use router B internet connection. Is this possible?

  • DNS pointing to different IPs from different parts of the world

    - by David
    I have a domain name that for some reason is pointing to different servers depending on where you are located in the world. What is odd is that I have another domain that has the same DNS servers, which points to the same server regardless of your location (which is the way it's mean't to work). Any ideas why the first domain is pointing to different IP addresses for different people?

  • VPN on a ubuntu server limited to certain ips

    - by Hultner
    I got an server running Ubuntu Server 9.10 and I need access to it and other parts of my network sometimes when not at home. There's two places I need to access the VPN from. One of the places to an static IP and the other got an dynamic but with DynDNS setup so I can always get the current IP if I want to. Now when it comes to servers people call me kinda paranoid but security is always my number one priority and I never like to allow access to the server outside the network therefor I have two things I have to have on this VPN. One it shouldn't be accessiable from any other IP then these 2 and two it has to use a very secure key so it will be virtually impossible to bruteforce even from the said IP´s. I have no experience what so ever in setting up VPNs, I have used SSH tunneling but never an actuall VPN. So what would be the best, most stable, safest and performance effiecent way to set this up on a Ubuntu Server? Is it possible or should I just set up some kind of SSH Tunnel instead? Thanks on beforehand for answers.

  • postfix relay access denied from some IPs

    - by Caballero
    This is driving me nuts. I have Postfix/Dovecot set up on Centos 6 VPS for my emails. I can send and receive emails without any problems on my outlook (home broadband), on my Android phone (3G connection), however when I set up exactly the same email account on Outlook at my friends house I'm getting bouncebacks when I'm trying to send email (receiving works fine): 554 5.7.1 : Relay access denied Now if it wasn't working at all I'd understand, but why is it working on several internet connections, but not everywhere? Can someone shed some light on this? Where should I look for the problem?

  • Recommended resource to understand Internet conventions IPs, CNAMES, *, MX etc

    - by Petras
    I am a programmer who has been creating websites for many years in shared hosting environments. To make the website live, I logged into where the domain was hosted and updated the name servers. Sometimes I didn’t want POP email so I changed an A record. I never really understood what this meant but it worked. Now we have a dedicated server and I have to fill out all this to make it live: Plus I was told I had to complete zones at my domain host: I would really like to know what all this means. What is a * record What is an @ How does the internet work regarding all these conventions? Is there a good approachable book on this topic?

  • Ways to do simple failover with one server and two IPs

    - by CrassHoppr
    The setup is one server (Windows 2008) at one location with two incoming connections. As the server has to interface with various on-site devices, and will have a small number of incoming connections, a data center is not an option, and instead cable/dsl connections must be used. The goal is that users visit https://service.site.com and are sent to either the primary IP address or a secondary IP if the primary is down. I've seen advice to use round robin DNS for this, but caching an IP for a downed interface is something I'd like to avoid. Is something like this possible with these constraints?

  • Can't ping IPs for devices not part of Windows Domain

    - by GiddyUpHorsey
    I have a home network with a Trendnet wireless router and a Windows Domain. The DNS server is on a Windows 2000 Server and is configured to forward queries to DNS servers provided by the ISP. The router provides DHCP and is configured with the Windows 2000 Server as the DNS server. When I connect iPhones to the network over WiFi, the router can ping the iPhones through its browser based admin interface, but Windows machines that are part of the Windows Domain cannot. A laptop was connected to the network over WiFi that wasn't joined to the domain and it could see the iPhones. All machines either have a fixed or DHCP allocated IP on the 192.168.0.* subnet. How do I configure the DNS server or the Windows Domain so that Windows machines can see the iPhones?

  • Cisco RV042 VPN with Dynamic IPs - Remote Gateway Not Resolving

    - by Rister
    I have an existing network setup that I inherited from my predecessor. Currently there are two sites, each with a Linksys RV042 VPN router running the 1.3.12.19-tm firmware. They are currently set up with a Gateway to Gateway VPN. One site has a static IP, the other has a Dynamic IP with a hostname set up on no-ip.com. My company is looking to set up another site so I purchased another RV042 only this one was Cisco branded and it is running the latest firmware. I had assumed that I would be able to configure a vpn from our main office (the dynamic ip) to the new site with this router quite easily. However when I set up a new VPN tunnel on either device, it stays on Waiting for Connection and the Remote Gateway shows an ip address of 0.0.0.0 rather than the remote ip address. The other VPN tunnel is still working and I don't see any obvious misconfiguration on the new router. It seems that the router is not resolving the Dynamic DNS address and therefore not giving me the option to connect the VPN. Does a Gateway to Gateway VPN work with Dynamic IP addresses on each end? Are the firmware versions not compatible? Is there something I've missed?

  • Setting up Mac VPN on simple network with separate IPs

    - by Dave
    Hi there, We have a pretty simple network configuration. A typical ASDL line with two extra IP addresses. We have a basic home network router Dlink DIR-655. We have two Mac OS X Snow Leopard Servers that we want to setup VPN on. The problem is that we can't change the ports which VPN works under ie. we can only setup port forwarding for UDP 500,1701,4500 to a single server. I'm wondering how we can cost effectively re-work our network so that we can take advantage of the separate IP addresses and have both VPNs working with the same router. Is that possible with our current hardware setup or do we need something more powerful? We're also toying with Mobile Access and wondering if that might be easier to setup. Expert help is greatly appreciated.

  • Amazon EC2: Instances, IPs and a wordpress blog (LAMP)

    - by JustinXXVII
    I had a link to my blog posted on Reddit yesterday and MySQL crashed on my EC2 Micro instance. I know I didn't have that many visitors because I used a marketing link that tracks hits. The link got 167 hits over the course of the last 18 hours, and MySQL crashed twice. So anyway, 167 visits is not a lot, so I've done some short term optimizations like restricting the number of Apache threads to limit the MySQL calls. I also set up WP Super Cache to serve static content. Soon I'm going to offload all of my images to S3 or CloudFront. So this leads me to my question. If this doesn't seem to help, and if i have another traffic "spike", how do AMIs work when you have a MySQL database? I think I understand that if you have more than one instance and assign the same Elastic IP to both of them, the incoming traffic gets distributed among both. But what happens when the MySQL database gets updated on one of the instances? I just need to wrap my mind around what happens when I create an AMI and then launch a new instance to help with traffic. Thanks for your suggestions.

  • Proxmox: VMs and different public IPs

    - by Raj
    I have a server which has two NICs and both are directly connected to internet. I have five different public IP addresses available for the VMs. The host machine (Proxmox) doesn't need to use any (it'll use a private IP and that's all) but will have internet connection. I've gone through the Proxmox documentation and I'm not able to understand the big picture to set up the right network configuration for my needs. In short, what I have is: One server (Proxmox, host machine) On that server, 5 VMs are created 5 public IP addresses available (one for each VM), let's say: 80.123.21.1, 80.123.21.2, 80.123.21.3, 80.123.21.4, 80.123.21.5 What I have now for the host is the following: auto lo iface lo inet loopback auto eth0 iface eth0 inet manual auto eth1 iface eth1 inet manual auto vmbr0 iface vmbr0 inet static address 192.168.1.101 netmask 255.255.255.0 bridge_ports eth0 bridge_stp off bridge_fd 0 auto vmbr1 iface vmbr1 inet manual It can be reached from the internal network, so that's OK. It has internet connection, which is also OK. vmbr1 is going to be used by the VMs. Each VM will have its own IP on his network interfaces configuration file. For some reason, VMs will not have internet and they won't be able to have public IP address. If I use NAT, it will work correctly, but they will not use the public allocated IP addresses for them. Am I missing something?

  • Separate Certificate by Subdomain (With multiple IPs)

    - by Brian
    Note: Yes, I realize this problem is easier to solve by just using 1 multi-domain or wildcard certificate. I wish to have an ASP.NET site running on IIS with 2 SSL domains sharing 1 web application but using separate certificates. Assuming I have 2 certificates, this can be solved on IIS7 as follows: Web Application1: Binding 1: http, 80, IP Address *, Host Name * Binding 2: https, 443, IPADDRESS1, using CERTDOMAIN1 (DOMAIN1 resolves to IPADDRESS1) Binding 3: https, 443, IPADDRESS2, using CERTDOMAIN2 (DOMAIN2 resolves to IPADDRESS2) That is to say, 2 certificates and 2 ip addresses, but both mapped to the same web application. In IIS6, the closest I have been able to come to this configuration is: Web Application1: Binding 1: http, 80, IPADDRESS1 Binding 2: https, 443, IPADDRESS1, using CERTDOMAIN1 (DOMAIN1 resolves to IPADDRESS1) Web Application2: Binding 1: http, 80, IPADDRESS2 Binding 2: https, 443, IPADDRESS2, using CERTDOMAIN2 (DOMAIN2 resolves to IPADDRESS2) That is to say, 2 certificates and 2 IP addresses, 2 web applications, both mapped to the same file location. The IIS6 solution is not optimal. Even if sharing an application pool, there are still costs associated with running the same site as two applications. Is upgrading from IIS6 to IIS7 a legitimate way to resolve this problem? Is there an IIS6 way to map 2 IP addresses within the same web application to different certificates?

  • Multiple IPs from one router

    - by ergoen
    I would like to know if it is possible (and if so, how) to configure a router running dd-wrt (or openwrt) to supply connected devices with two ip addresses. The network looks like this: [Internet] | [Router] | | [Comp1] [Comp2] ... My ISP provides me with enough public IP adresses to give all devices on my network one each. The easiest way to set that up is to just use the router as a switch. This will however lead to problems with some LAN based applications. I would still like to use Samba-shares between the computers as well as a vpn server. What I am looking for basically is if it is possible to use the router as a DHCP server for a local network (let's say giving IP adresses 192.168.1.xx to connected computers) while at the same time passing through public IP addresses to each as well?

  • Multiple SSL certificates on Apache using multiple public IPs - not working

    - by St. Even
    I need configure multiple SSL certificates on a single Apache server. I already know that I need multiple external IP addresses as I cannot use SNI (only running Apache 2.2.3 on this server). I assumed that I had everything configured correctly, unfortunately things are not working as they should (or maybe I should say, as I expected them to work)... In my httpd.conf I have: NameVirtualHost *:80 NameVirtualHost *:443 Lets say my public IP is 12.0.0.1 and my private IP is 192.168.0.1. When I use the public IP in my vhost my default website is being shown instead the one defined in my vhost, e.g.: <VirtualHost 12.0.0.1:443> ServerAdmin [email protected] ServerName blablabla.site.com DocumentRoot /data/sites/blablabla.site.com ErrorLog /data/sites/blablabla.site.com-error.log #CustomLog /data/sites/blablabla.site.com-access.log common SSLEngine On SSLCertificateFile /etc/httpd/conf/ssl/blablabla.site.com.crt SSLCertificateKeyFile /etc/httpd/conf/ssl/blablabla.site.com.key SSLCertificateChainFile /etc/httpd/conf/ssl/blablabla.site.com.ca-bundle <Location /> SSLRequireSSL On SSLVerifyDepth 1 SSLOptions +StdEnvVars +StrictRequire </Location> </VirtualHost> When I use the private IP in my vhost everything works as it should (the website defined in my vhost is being shown), e.g.: <VirtualHost 192.168.0.1:443> ...same as above... </VirtualHost> My server is listening on all interfaces: [root@grbictwebp02 httpd]# netstat -tulpn | grep :443 tcp 0 0 0.0.0.0:443 0.0.0.0:* LISTEN 5585/httpd What am I doing wrong? If I cannot get this to work I cannot continue to add the second SSL certificate on the other public IP... If more information is required just let me know!

  • OpeVPN log connecting client IPs

    - by TossUser
    I looking for the best solution to log all connecting client's ip to either a text file or a database who logs into my VPN server. Under the IP I mean the public WAN IP on the internet where they are connecting from. A hack could definitely be to make the openvpn server log to a separate logfile and run logtail periodically to extract the necessary information. So the database I want to build would look like: Client_Name | Client_IP | Connection_date roadwarr1 | 72.84.99.11 | 03/04/14 - 22:44:00 Sat Please don't recommend me to use the commercial Openvpn Access Server. That's not a real solution here. If the disconnection date could be determined that would be even better so I could see how long a client was connected and from where! Thank you

  • Connecting two IPs like an URL

    - by czesuaf
    I haven't found answer anywhere, so here comes the question. My ISP connected me to a router with thousands of other clients, so my public IP is the same as many others. And I want to make a small private server which can be accessible across whole web. So my home router shows me IP 10.x.x.x and actually my public IP is 89.x.x.x. Is there any way to reach the IP 10.x.x.x from the Internet? Yeah I thought the same about IPv6 but it's still not accessible for me ;[

  • Try all available WSDL IPs with JAX-WS

    - by Asaf
    I'm using JAX-WS to open a service port. When the DNS exposes two IPs for the DNS entry (of the WSDL), the Service tries to use only the first - resulting in a "Failed to access the WSDL at: http://some.url.com/someDocument?wsdl. It failed with: Connection refused: connect" exception. I've found an issue filed against JAX-WS, but with no resolution. this is the comment that describes my problem best. The code is just a one-liner: Service service = Service.create("http://some.url.com/someDocument?wsdl", engineQName); the smarts is exposing those two A records on http://some.url.com/ at the DNS. Can anyone help? 10x,

  • fail2ban regex working but no action being taken

    - by fpghost
    I have the following snippet of fail2ban configuration on Ubuntu 13.10 server: #jail.conf [apache-getphp] enabled = true port = http,https filter = apache-getphp action = iptables-multiport[name=apache-getphp, port="http,https", protocol=tcp] mail-whois[name=apache-getphp, dest=root] logpath = /srv/apache/log/access.log maxretry = 1 #filter.d/apache-getphp.conf [Definition] failregex = ^<HOST> - - (?:\[[^]]*\] )+\"(GET|POST) /(?i)(PMA|phptest|phpmyadmin|myadmin|mysql|mysqladmin|sqladmin|mypma|admin|xampp|mysqldb|mydb|db|pmadb|phpmyadmin1|phpmyadmin2|cgi-bin) ignoreregex = I know the regex is good, because if I run the test command on my access.log: fail2ban-regex /srv/apache/log/access.log /etc/fail2ban/filter.d/apache-getphp.conf I get a SUCCESS result with multiple hits, and in my log I see entries like 187.192.89.147 - - [13/Apr/2014:11:36:03 +0100] "GET /phpTest/zologize/axa.php HTTP/1.1" 301 585 "-" "-" 187.192.89.147 - - [13/Apr/2014:11:36:03 +0100] "GET /phpMyAdmin/scripts/setup.php HTTP/1.1" 301 593 "-" "-" Secondly I know email is configured correctly, as each time I service fail2ban restart I get an email for each of the filters stopping/starting. However despite all this no action seems to be taken when one of these requests comes in. No email with whois, and no entries in iptables. What possibly could be preventing fail2ban from taking action? (everything looks in order in fail2ban-client -d and I can see the chains have loaded with iptables -L)

    So I have 1 computer with 5 IP's and around 15 sites being hosted. I have 4 of the ips setup to be dedicated for 4 sites and the rest share the 5th ip. When I'm setting up my name server, do I set it up at Godaddy my Registar or on my server's dns or both? Can I just setup NS1 - Add all the ips NS2 - Add all the ips And just have all the sites use those two name servers?

  • To have multiple sites with similar content on the same server but different IPs?

    - by Eugene
    I have 7 different sites on the same dedicated server. Two major sites have different IPs, and 5 small share the same IP. About first 2 they have similar content, but not the same. Basically they have different: URLs Titles Meta Data But they both have the same niche. I was thinking about two strategies. One is to move one of the sites (from 2 first one) on different server or move 5 other sites on different server. But I'm not sure which way is better. My questions are: Wouldn't be better from SEO stand point, to move those 2 sites on different servers? Does it worth it to spend for additional server? Do you know if Google penalize sites for similar content on the same server with different IPs?

  • Direct TCP/IP connections in P2P apps

    - by Greg Roberts
    From a Joel's post on Copilot: Direct Connect! We’ve always done everything we can to make sure that Fog Creek Copilot can connect in any networking situation, no matter what firewalls or NATs are in place. To make this happen, both parties make outbound connections to our server, which relays traffic on their behalf. Well, in many cases, this isn’t necessary. So version 2.0 does something rather clever: it sets up the initial connection through our servers, so you get connected right away with 100% reliability. But then once you’re all connected, it quietly, in the background, looks for a way to make a direct connection. If it can’t, no big deal: you just keep relaying through our server. If you can make a direct peer-to-peer connection, it silently shifts your data onto the direct connection. You won’t notice anything except, probably, much faster communication. How do they change the server connection to a P2P connection?

  • Filtering your offices IPs from Google Analytics when each has a dynamic IP?

    - by leeand00
    I found the documentation for filtering IPs from Google Analytics, but the address of the several locations of our company all have dynamic IP addresses that change every 30 days from what I'm told. I know from working with Dynamic DNS that the provider usually gives you a script that you configure your router to run when it's IP address changes or when it is restarted, which passes the new IP address to the DDNS server. I'm wondering if there might be a way to write or use a preexisting script to do the same thing with the Google Analytics API.
