  • Mac Snow Leopard Server DNS

    - by panomedia
    I have a Tomcat-driven application on my Windows server that I am planning to move to a MacMiniServer. Before I do this, I want to fully test the transition for licensing purposes. I have a Fire drive setup with Snow Leopard Server and the base app runs just fine BUT I need to be able to resolve the URL to my domain and not localhost. So, I figured I would setup panomedia.net in the DNS Server and also create an A record to my internal network IP so www.panomedia.net would dish out the same thing as localhost. The problem is: The Tomcat web app starts up going through panomedia.local and not through www.panomedia.net and My main network preference panel is still looking at my Comcast DNS search providers even though I put my local IP address as the only DNS Server and Search provider. I need to test this via an actual domain name before I commit to a 400GB data move. Can anyone help?

  • 1 Computer Pulls Wrong DNS Every Morning

    - by bradenkeith
    One of my users takes his laptop home, connects to his internal network fine. He brings it in every morning and since Monday - every morning it pulls the wrong DNS every time. It pulls 1 DNS: 192.168.1.1 which is the router. The DNS are external IPs. I have several users that take their laptops home and connect to other networks - what could cause this anomaly? He's booting up when he comes in the office and a simple ipconfig /release /renew fixes the issue.

  • Reverse proxy for mailserver (SMTP + HTTP for web client)

    - by gaqzi
    I'm looking at doing some reverse proxy work for a mail server with corresponding web client. Both servers are running on the same machine, this is not a server with a high load. :) The solution I've discussed with friends is having the mail server/web client on our internal network. Then to put a reverse proxy on the DMZ to service both SMTP and web client HTTP-traffic to the mail server on the internal network. From what I understand this is the recommended secure solution? So far I've thought for the SMTP-proxy part of using postfix which will receive mail, do some spamhause and similar anti-spam measures and if it all checks out, send the mail to the mail server on the inside. The mail server on the inside will send all outgoing mail to the proxy which will then send it out on the Internet. For the web client I'm not sure exactly which software I should be running on the proxy machine, I've been thinking about using Squid -- but that's basically based on the fact that I know squid is a http proxy. The web client data will be sent out over SSL. Reading around some here on Serverfault I've seen other people using Apache with mod_proxy+mod_security for similar situations. Am I thinking correctly for this solution? What software would you guys use and with which modules? Thanks in advance for the help! :)

  • Ubuntu 12.04 - Pound Reverse Proxy and Adobe Flex/Flash Auth

    - by James
    First time posting, I have a completely fresh install of ubuntu 12.04 Client as a reverse proxy gateway to our internal network. Our setup is we have one external ip but three domains we would like to point to various webservers on our internal network. It's not so much a load balancing issue or cacheing etc. Merely routing some Client browsers to a port 80 webpage (to adhere to some stricter corporate policies regarding placing port numbers after domain names). I have gone with pound and everything seems to be working fine. Static pages load etc. Everything is good with the exception of a Flash/Flex based WebClient for a Digital Asset Management program. The actual static page loads fine, it is just at the moment of entering credentials, be they correct or incorrect, and hitting login, there is no response whatsoever. Either a rejection or confirmation etc. So the request back to the internal server can't be getting through. I have googled extensively and there might be a solution in a crossdomain.xml file? Documentation isn't very clear. And we are not the authors of the DAM app, and have no control over the code on the Flash/Flex side. Questions: Is there a particular config file/solution for pound that allows Flash/Flex auth information to be forwarded? Is there another reverse proxy program (nginx?)that allows this type of config? Am I looking at this the entire wrong way, should Flash/Flex fundamentally not be allowed to have this access?

  • Using IIS7 as a reverse proxy

    - by Jon
    My question is pretty much identical to the question listed but they did not get an answer as they ended up using Linux as the reverse proxy. http://serverfault.com/questions/55309/using-iis7-as-a-reverse-proxy I need to have IIS the main site and linux (Apache) being the proxied site(s). so I have site1.com (IIS7) site2.com (Linux Apache) they have subdomains of sub1.site1.com sub2.site1.com sub3.site2.com I want all traffic to go to site1.com and to say anything that is site2.com should be proxied to linux box on internal network, (believe ARR can do this but not sure how). I can not have it running as Apache doing the proxying as I need IIS exposed directly. any and all advice would be great. EDIT I think this might help me: <rule name="Canonical Host Name" stopProcessing="true"> <match url="(.*)" /> <conditions> <add input="{HTTP_HOST}" negate="true" pattern="^cto\.com$" /> <add input="{HTTP_HOST}" negate="true" pattern="^antoniochagoury\.com$" /> <add input="{HTTP_HOST}" negate="true" pattern="www.antoniochagoury\.com$" /> </conditions> <action type="Redirect" url="http://www.cto20.com/{R:1}" redirectType="Permanent" /> </rule> from: http://www.cto20.com/post/Tips-Tricks-3-URL-Rewriting-Rules-Everyone-Should-Use.aspx I will have a look at this when I have access to the IIS7 box. Thanks

  • plesk: how to configure reverse proxy rules properly?

    - by rvdb
    I'm trying to configure reverse proxy rules in vhost.conf. I have Apache-2.2.8 on Ubuntu-8.04, monitored by Plesk-10.4.4. What I'm trying to achieve is defining a reverse proxy rule that defers all traffic to -say- http://mydomain/tomcat/ to the Tomcat server running on port 8080. I have mod_rewrite and mod_proxy loaded in Apache. As far as I understand mod_proxy docs, entering following rules in /var/www/vhosts/mydomain/conf/vhost.conf should work: <Proxy *> Order deny,allow Allow from all </Proxy> ProxyRequests off RewriteRule ^/tomcat/(.*)$ http://mydomain:8080/$1 [P] Yet, I am getting a HTTP 500: internal server error when requesting above URL. (Note: I decided to use a rewrite rule in order to at least get some information logged.) I have made mod_rewrite log extensively, and find following entries in the logs [note: due to a limitation of max. 2 URLs in posts of new users, I have modified all following URLs so that they only contain 1 slash after http:. In case you're suspecting typos: this was done on purpose): 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) init rewrite engine with requested uri /tomcat/testApp/ 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (3) applying pattern '^/tomcat/(.*)$' to uri '/tomcat/testApp/' 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) rewrite '/tomcat/testApp/' - 'http:/mydomain:8080/testApp/' 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (2) forcing proxy-throughput with http:/mydomain:8080/testApp/ 81.241.230.23 - - [19/Mar/2012:16:42:59 +0100] [mydomain/sid#b06ab8][rid#1024af8/initial] (1) go-ahead with proxy request proxy:http:/mydomain:8080/testApp/ [OK] This suggests that the rewrite and proxy part is processed ok; still the proxied request produces a 500 error. Yet: Addressing the testApp directly via http:/mydomain:8080/testApp does work. The same setup does work on my local computer. Is there something else (Plesk-related, perhaps?) I should configure? Many thanks for any pointers! Ron

  • I need a reverse proxy solution for SSH

    - by Bond
    Hi here is a situation I have a server in a corporate data center for a project. I have an SSH access to this machine at port 22.There are some virtual machines running on this server and then at the back of every thing many other Operating systems are working. Now Since I am behind the data centers firewall my supervisor asked me if I can do some thing by which I can give many people on Internet access to these virtual machines directly. I know if I were allowed to get traffic on port other than 22 then I can do a port forwarding. But since I am not allowed this so what can be a solution in this case. The people who would like to connect might be complete idiots.Who may be happy just by opening putty at their machines or may be even filezilla.I have configured an Apache Reverse Proxy for redirecting the Internet traffic to the virtual machines on these hosts.But I am not clear as for SSH what can I do.So is there some thing equivalent to an Apache Reverse Proxy which can do similar work for SSH in this situation. I do not have firewall in my hands or any port other than 22 open and in fact even if I request they wont allow to open.2 times SSH is not some thing that my supervisor wants.

  • Reverse Proxy issues IIS on Windows Server 2012

    - by ahwm
    I've tried searching, but nothing seems to be working. I have a feeling it might be due to our custom Rewrite module. Here is the excerpt from the web.config that sets it up: <modules runAllManagedModulesForAllRequests="true"> <add name="UrlRewriteModule" type="EShop.UrlRewriteModule"/> </modules> EShop.UrlRewriteModule is a custom class in App_Code which handles incoming requests. I have set up the rewrite rules but it doesn't seem to want to work. I'm inclined to think that our rewrite class is interfering earlier than the proxy rules and saying that the page doesn't exist. Here's what we're trying to accomplish: We are working on a new site for a client, but they have a forum that they're not likely to want to move. I set up a new subdomain to point to the new server while the site is being completed (before we go live) and want the reverse proxy to forward test.domain.com/forum to www.domain.com/forum. After the site goes live, we'll need to forward using an IP address instead. I've set up a reverse proxy successfully with nginx, but we didn't want to set up another server if we didn't need to. Ideas?

  • Why can I resolve this hostname but not a cname to this hostname?

    - by Joe Hopfgartner
    if a run dig against a hostname, i get the according cname, however i get an NXDOMAIN error (non existent domain). if i run dig against the cname i got, I can resolve it to an IP address successfully. It is reproduceable. On the system I am currently on it is always the case, on other systems it sometimes works and sometimes not, and on other systems it seems to work all the time. If i run using a nameserver i specify (for example googles public nameserver) i can successfully resolve the hostname. i would just blame the local system, but it seems i am not having the only one problems the 2nd domain (unrestrict.me) is hosted on amazon route 53 nameservers. the 1st one on another dns server which has proofen to be fully functional and reliable over the years. i once switchted with the other domain to amazon dns as well, everything seemed to work, also various dns health check tests reported fine, however i recieved a lot of support tickets that dns resolution would not work. is amazon just "bad" or am i doing something wrong? i did not tamper with the domain in any way on the local system (in case of caching or making a custom dns view or whatever...) joe@joe:~$ dig scorpion.premiumize.me ; <<>> DiG 9.8.1-P1 <<>> scorpion.premiumize.me ;; global options: +cmd ;; Got answer: ;; ->>HEADER<<- opcode: QUERY, status: NXDOMAIN, id: 10222 ;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 0 ;; QUESTION SECTION: ;scorpion.premiumize.me.

  • Setting up a DNS name server for a mass virtual host with Bind9

  • DNS: how to get local server to superimpose results over authoritative server?

    - by growse
    I've got a domain for which the DNS I control, and is hosted on the internet. I also have a NAT'd internal network (192.168.0.0/24) which has internet access, and which I also control. On this internal network, I also have a DNS resolver. DNS software on both is PowerDNS. What I want to be able to do is for the DNS resolver on the internal network to be able to add/change records of queries and results that come down from the authoritative server. For example, the authoritative server might have a single record for animal.example.com: animal.example.com. IN AAAA 2001:140:283::1 However, I'd like it so that when internal clients do a dns lookup for animal.example.com, they might get back the following: animal.example.com. IN AAAA 2001:140:283::1 animal.example.com. IN A 192.168.0.2 Obviously, I could set up the internal DNS server to pretend to be authoritative for example.com, but that would require a fair bit of effort to keep the main DNS server and the internal DNS server in sync for the records which are the same between both. If the internal DNS server could somehow be made a slave of the main DNS server, but also have the provision to add its own results in, that would be ideal. Is this possible?

  • Server 2003 PDC DNS not working..Failover server is...

    - by Seth
    In the midst of trying to utilize proc power, i create a fault tolerant DNS server a while ago. Since, Ive been trying to add another controller for exchange. So I thought I would revert back to a single primary DNS for the meantime and now Im balancing on a thread. The server i thought I uninstalled DNS, is still acting as DNS. And now the PDC does not resolve. Can anybody walk me through, Im overwhelmed and cant think straight... Im afraid if anyone restarts their machine they wont have internet. Update Ok so from the beginning. I was configuring Exchange on a new server 2008. How it happened I dont know, but it started to not resolve DNS. (exclamation mark on NIC) even though everything was static. So ultimately I decided to remove the server from the problem, because I noticed DNS was in disarray if I used the DNS IP of the first server. This is when I tested with nslookup on each DNS server. I had uninstalled DNS from the second server, but nslookup was still resolving with that IPaddress, which has me all wound up cause I dont understand. So, since the first DNS server isn't resolving, Im assuming if the second one isnt configured right I'll loose internet. Im just confused and dont know where to start troubleshooting...

  • How can I stop Windows DNS server properties settings from changing by themselves?

    - by paradroid
    When I open the DNS console in Administrative tools, I keep finding a couple of problems which keep on reappearing by themselves, and I want to stop them from happening. One of the DNS servers has two network interfaces, and it should only be listening for requests on of them, and I get errors in the Event Log otherwise. But when right clicking one DNS server and selecting Properties, I can see on the Interfaces tab that 'All IP addresses' is selected. If I Change it to 'Only the following IP addresses:' and deleselect the WAN addess, I will find it reslected when I next check it after a couple of days. In the other DNS server's Properties, on the Forwarders tab, there should only be two forwarder addresses. However, the address for the router keeps in appearing. This router has the DNS server as its forwarder. There shouldn't be anything using the router's DNS forwarders for DNS other than the router itself, but this surely is causing a loop. How do I get these properties on both DNS servers to stick?

  • Pushing DNSSEC updates with offline keys

    - by eggyal
    In a non-professional capacity, I look after the DNS of some 18 domains: mostly personal/vanity domains for immediate family. I outsource the whole shebang to an inexpensive managed hosting provider with a web interface through which I manage the zones; since the provider also offers DNSSEC, I have successfully deployed that too. These domains are so unimportant that an attack targetted against them seems much less likely than a general compromise of my provider's systems, at which point the records of all their customers might be changed to misdirect traffic (perhaps with extremely long TTLs). DNSSEC could protect against such an attack, but only if the zone's private keys are not held by the hosting provider. So, I wonder: how can one keep DNSSEC private keys offline yet still transfer signed zones to an outsourced DNS host? The most obvious answer (to me, at least) is to run one's own shadow/hidden master (from which the provider can slave) and then copy offline-signed zonefiles to the master as required. The problem is that the only machine I (want to*) control is my personal laptop, which usually connects from a typical home ADSL (behind NAT over a dynamically-assigned IP address). Having them slave from that (e.g. with a very long Expiry time on the zone for periods when my laptop is offline/unavailable) would not only require a Dynamic DNS record from which they can slave (if indeed they can slave from a named host rather than a static IP address), but would also involve me running a DNS server on my laptop and opening both it and my home network up to the incoming zone transfer requests: not ideal. I would prefer a much more push-oriented design, whereby my laptop initiates transfer of offline-signed zonefiles/updates to the provider's servers. I looked into whether nsupdate could fit the bill: documentation is a little sketchy, but my testing (with BIND 9.7) suggests it can indeed update DNSSEC zones, but only where the server holds the keys to perform the zone signing; I have not found a way to have it take an update including the relevant RRSIG/NSEC/etc. records and have the server accept them. Is this a supported use-case? If not, I suspect the only solutions which could fit the bill will involve non-DNS-based transfer of the zone updates and would welcome recommendations that are supported by (hopefully inexpensive) hosting providers: SFTP/SCP? rsync? RDBMS replication? Proprietary API? Finally, what would be the practical implications of such a setup? Key rotation is jumping out at me as being an obvious difficulty, especially if my laptop is offline for extended periods. But the zones are extremely stable, so perhaps I could get away with long-lived ZSKs**...? * Whilst I could run a shadow/hidden master on e.g. an outsourced VPS, I dislike the overhead of having to secure / manage / monitor / maintain yet another system; not to mention the additional financial costs of so doing. ** Okay, this would enable a concerted attacker to replay outdated records—but the risk and impact of such are both tolerable in the case of these domains.

  • Only one domain is not resolving via Windows DNS server at multiple locations, but is at others

    - by Brett G
    I'm having quite a weird issue. Had mail delivery issues to a specific domain. After looking closer, I realized that the DNS for that domain isn't resolving via the in-house Windows 2003 SP2 DNS server. C:\>nslookup foodmix.net Server: DC.DOMAIN.com Address: 10.1.1.1 DNS request timed out. timeout was 2 seconds. DNS request timed out. timeout was 2 seconds. *** Request to DC.DOMAIN.com timed-out (DC.DOMAIN.com and 10.1.1.1 are generic values to replace the actual ones) Even if I run this nslookup from the DC.DOMAIN.com server, I get the same result. However, all other requests are working as they should. I had a sysadmin friend try this DNS lookup on servers at several companies that he consults for (which are also Windows 2003 AD servers). The weird thing is some of these were having the same exact issue. However using public DNS servers work. I have tried clearing the DNS cache, restarting the server, restarting the services, etc. Nothing has worked. One weird event I noticed in the DNS Server Event Logs that might be related is an event ID of 5504 with the following description: The DNS server encountered an invalid domain name in a packet from 192.33.4.12. The packet will be rejected. The event data contains the DNS packet. For more information, see Help and Support Center at http://go.microsoft.com/fwlink/events.asp. In the data section below, I can see the following mentioned: ns2.webhostingstar.com Which happens to be the nameserver for the domain in question. Several discussion threads and a MS KB have pointed to disabling EDNS. I have done this via "dnscmd /config /enableednsprobes 0" and it has not fixed the issue.

  • Can squid forward DNS queries to a DNS server?

    - by pravin
    This might something be completely impossible to achieve, but before I give it a shot thought I might get some advice from a fellow geek. Would squid proxy DNS queries as well? I would like to forward DNS queries to go through squid and use squid's DNS error page, of course by customizing it. I see the DNS queries are hitting my squid box on UDP port 53. I can setup a port forwarding so that all these queries get sent to squid's port 3128. But would squid understand its a DNS query and forward those queries to the dns server set in squid.conf? I hope my question is clear but please shout up and I would be glad to give you some more info if needed. Thanks guys!

  • Add DNS suffixes to a Sonicwall PRO2040 firewall?

    I want to have our network pass out DNS suffixes with the DHCP assignments, so that we don't need to add them to the TCP/IP settings on each computer. Our DHCP is not being handled by an actual server box, but by our Sonicwall firewall, which is a PRO 2040. Can this firewall be set up to append DNS suffixes? Thanks!

  • Rackspace Cloud Server DNS Add SPF Records

    - by user625435
    I've setup my new LAMP server on Rackspace Cloud and the Basic A, C and MX DNS setup is no problem. I need to add an SPF record for a project I am migrating over to this new server that allows emails from a 3rd party server and I can't seem to figure out how to do this. There doesn't seem to be an option to add a TXT record in my Rackspace Cloud Server interface and I installed the BIND DNS on my Apache server, but I am not sure how to get that to been seen, etc.

  • DNS down in Anonymous attack

    - by Tal Weiss
    As I'm writing this our company website and the web-service we developed are down in the big GoDaddy outage resulting from an Anonymous attack (or so says Twitter). We used GoDaddy as our registrar and we use it for DNS for some domains. Tomorrow is a new day - what can we do to mitigate such outages? Simply moving to, say, Route 53 for DNS might not be enough. Is there any way to remove this single point of failure?

  • Reverse proxy setup for distributed storage

    - by vise
    I have 4 file servers that I want to access under a single mount point from another server. This server has a web application that should serve content from the mounted point. I think I can achieve this with glusterfs. Considering that the file servers have fairly powerful hardware, I want to install a webserver on each of them and serve those files via a reverse proxy. Any thoughts on how I may be able to do so?

    - by Lukes123
    We have just changed our DNS record to point to a new server running IIS. How long will it take until the address is changed to the new server? Some people can still see the old server and some can see the new. I have flushed the dns on my pc and it seems to be fine although it doesn't with another of my pcs. Thanks
