  • Sharing one static ip for both ftp and www service

    - by user11496
    Trying to figure out how to update the Zone record and configure webserver so that one application on the webserver is accessible by public. I'm completely not good at NS/DNS/NAT/firewall/routing/port forwarding/networking etc. "faraday" is the intranet name. Everyone within local network can access all applications hosted on "faraday". Hostname for webserver is "www", FTP server is "ftpserver". Both servers running RHEL4 OS. The goal is to allow anyone outside the company network (public) to access only one of the many applications on "faraday". Hope somebody can help me with some of the questions below, if not all. From zoneedit record, the static IP is used by FTP now. Can I use the same existing static IP - 219.95.10.100, for web service? Currently anyone who enter "http://www.abc.com.my" will be directed to "http://www.abc.com". I don't want this to change. Currently, no one else, except employee on local network, can access "faraday" web pages. How to configure so that when anyone type "http://thisapp.abc.com.my" on their web browser, the url will lead them to "http://faraday/thisapp" (application folder is /var/www/html/thisapp on RHEL4 web server). If possible, how to set the URL will continue to show "http://thisapp.abc.com.my" instead of "http://faraday/thisapp" How to limit/restrict user (those who are not from local network) so they only have access to "http://thisapp.abc.com.my", but not "http://faraday" or "http://faraday/anotherapp", etc. What's the configuration changes needed in /etc/httpd.conf on web server? Company domain name is "abc.com.my". Following is the zone records on www.zoneedit.com. Subdomain Type IP sdsl A 219.95.10.100 ftp CNAME sdsl.abc.com.my @ NS ns3.zoneedit.com @ NS ns7.zoneedit.com WebForward record: New Domain Destination Cloaked www.abc.com.my http://www.abc.com N On my local DNS server, there are 2 zone files: abc.com.my and pnmy.abc.com. > cat abc.com.my.zone ftp CNAME ftp.pnmy.abc.com. sdsl A 219.95.10.100 > cat pnmy.abc.com.zone ftp CNAME ftpserver ftpserver A 172.16.5.1 faraday CNAME www www A 172.16.5.2

  • Dynamic Bind9 + DHCP

    - by AcidRod75
    i have been working on setup a server for my internal network, so far i have a working isc-dhcp-server that can upgrade a chrooted BIND9 (on the same machine), i need to add some static entries on the DNS, so users can resolve the websites that resides in our DMZ. What i had tryed all ready was to modify the /etc/bind/named.conf.local with this info: // // Do any local configuration here // // Consider adding the 1918 zones here, if they are not used in your // organization //include "/etc/bind/zones.rfc1918"; key DHCP_UPDATER { algorithm HMAC-MD5.SIG-ALG.REG.INT; secret "MySuperSecretHash"; (this is not the real value BTW) }; zone "quality.internal" IN { type master; file "/var/lib/bind/quality.internal.db"; allow-update { key DHCP_UPDATER; }; }; zone "0.10.10.in-addr.arpa" { type master; file "/var/lib/bind/rev.10.10.0.in-addr.arpa"; allow-update { key DHCP_UPDATER; }; }; logging { channel query.log { file "/var/log/named/query.log"; severity debug 3; }; category queries { query.log; }; }; --- EOF ---- then i added this 2 entries: zone "ourserver.internal" IN { type master; file "/var/lib/bind/ourserver.internal.db"; }; zone "0.16.172.in-addr.arpa" { type master; file "/var/lib/bind/rev.172.16.0.in-addr.arpa"; }; ---- EOF ---- So.. i created the files ourserver.internal.db and rev.172.16.0.in-addr.arpa placed them BOTH in /var/lib/bind/ and changed the permisions so the bind user can access them, restated the service... when i do a NSLOOKUP www.ourserver.internal i get: Server: 127.0.0.1 Address: 127.0.0.1#53 ** server can't find www.ourserver.internal: NXDOMAIN BUT when i do a reverse lookup.... Server: 127.0.0.1 Address: 127.0.0.1#53 5.0.16.172.in-addr.arpa name = www.ourserver.internal I do not understand what's wrong. Some help with this will save me from installing a new DNS server at the DMZ JUST to host internal site names- TY in advance BTW: the server i'm using has Ubuntu Server 11.10 fully patched.

  • Redirect/Rewrite Subdomain to Subfolder

    - by Laurent Ho
    I'm trying to redirect a subdomain to a subfolder e.g. forums.domain.com to www.domain.com/forums Note that I started the forums in the subfolder format but worried that members might mistakenly try to access the forums using the subdomain format. RewriteCond %{HTTP_HOST} ^(www\.)?forums\.domain\.com RewriteRule .* /forums [L] From what I read the codes above should work through .htaccess, but do I still need to create a DNS A record to point to the IP address of the server?

  • ubuntu 12.04 server doesn't resolve local domain name

    - by jdog
    After apt-get upgrade this morning, my Ubuntu 12.04 web server does no longer resolve a domain name hosted on it. I also received the error message: "resolvconf: Error: /etc/resolv.conf isn't a symlink, not doing anything." I found this question Network Manager not populating resolv.conf but the solutions provided there did not resolve the problem. Creating the symlink in fact caused websites to load very slowly, so I assume there is some sort of (reverse?) DNS lookup not working, when I create the symlink.

  • Forwarding naked domain to www [duplicate]

    - by mravec
    This question already has an answer here: Why is www. working but no-www is not? 1 answer I successfully mapped my www.mydomain.com to my Google site (as described here). However I would like to forward also my naked domain (mydomain.com) to end up in www.mydomain.com. I assume I should modify 'A' DNS record in my provider but what IP should I point it to?

  • Fail to access Network options

    - by Konstantinos Marinis
    I am trying to use OpenDNS for my newly installed Ubuntu 12.10... However I cannot insert custom DNS addresses... I am accessing Network, then at my wireless connection, no matter how many times I press the "options" tab at the low right corner (I am not using english Ubuntu, so the button might have a different name), nothing happens. Any ideas why or how should I configure my OpenDNS connection?

  • C# - Determine if class initializaion causes infinite recursion?

    - by John M
    I am working on porting a VB6 application to C# (Winforms 3.5) and while doing so I'm trying to break up the functionality into various classes (ie database class, data validation class, string manipulation class). Right now when I attempt to run the program in Debug mode the program pauses and then crashes with a StackOverFlowException. VS 2008 suggests a infinite recursion cause. I have been trying to trace what might be causing this recursion and right now my only hypothesis is that class initializations (which I do in the header(?) of each class). My thought is this: mainForm initializes classA classA initializes classB classB initializes classA .... Does this make sense or should I be looking elsewhere? UPDATE1 (a code sample): mainForm namespace john { public partial class frmLogin : Form { stringCustom sc = new sc(); stringCustom namespace john { class stringCustom { retrieveValues rv = new retrieveValues(); retrieveValues namespace john { class retrieveValues { stringCustom sc = new stringCustom();

  • recursion tree and binary tree cost calculation

    - by Tony
    Hi all, I've got the following recursion: T(n) = T(n/3) + T(2n/3) + O(n) The height of the tree would be log3/2 of 2. Now the recursion tree for this recurrence is not a complete binary tree. It has missing nodes lower down. This makes sense to me, however I don't understand how the following small omega notation relates to the cost of all leaves in the tree. "... the total cost of all leaves would then be Theta (n^log3/2 of 2) which, since log3/2 of 2 is a constant strictly greater then 1, is small omega(n lg n)." Can someone please help me understand how the Theta(n^log3/2 of 2) becomes small omega(n lg n)?

  • How shared hostings, domain names and DNS work together?

    - by vtortola
    Hi, I 've this little doubt but I couldn't find information about it, probably because I'm not searching the correct thing. When a browser ask for "www.mydomain.com", the DNS server returns an IP Address, then the browser go there... but what does happen then? I mean, that IP address could be a shared hosting that contains hundreds of web pages and domains, so how does it knows where it have to go? Is something that the web server does? is it something that I could implement in a web application? I mean, for example I have a web application that contains accounts, and each account has a default web page. You could access that page passing the account namne, for example "www.mydomain.com/myaccount", but now I want to register "www.myaccount.com" and then it will get the "www.mydomain.com/myaccount" content. Is it possible? Kind regards.

  • DNSSEC - What doesn't it cover?

    - by KP65
    I'm currently revising for an exam to do with DNS/DNSSEC. While I know DNSSEC provides various security enhancements for DNS, I would like to dive a bit deeper(for my own thirst for knowledge!) and would like to know what is still problematic security wise even after DNSSEC is employed? After all it can't have solved all programs DNS was having with regards to security, right? Thanks

  • How to prevent delays associated with IPv6 AAAA records?

    - by Nic
    Our Windows servers are registering IPv6 AAAA records with our Windows DNS servers. However, we don't have IPv6 routing enabled on our network, so this frequently causes stall behaviours. Microsoft RDP is the worst offender. When connecting to a server that has a AAAA record in DNS, the remote desktop client will try IPv6 first, and won't fall back to IPv4 until the connection times out. Power users can work around this by connecting to the IP address directly. Resolving the IPv4 address with ping -4 hostname.foo always works instantly. What can I do to avoid this delay? Disable IPv6 on client? Nope, Microsoft says IPv6 is a mandatory part of the Windows operating system. Too many clients to ensure this is set everywhere consistently. Will cause more problems later when we finally implement IPv6. Disable IPv6 on the server? Nope, Microsoft says IPv6 is a mandatory part of the Windows operating system. Requires an inconvenient registry hack to disable the entire IPv6 stack. Ensuring this is correctly set on all servers is inconvenient. Will cause more problems later when we finally implement IPv6. Mask IPv6 records on the user-facnig DNS recursor? Nope, we're using NLNet Unbound and it doesn't support that. Prevent registration of IPv6 AAAA records on the Microsoft DNS server? I don't think that's even possible. At this point, I'm considering writing a script that purges all AAAA records from our DNS zones. Please, help me find a better way. UPDATE: DNS resolution is not the problem. As @joeqwerty points out in his answer, the DNS records are returned instantly. Both A and AAAA records are immediately available. The problem is that some clients (mstsc.exe) will preferentially attempt a connection over IPv6, and take a while to fall back to IPv4. This seems like a routing problem. The ping command produces a "General failure" error message because the destination address is unroutable. C:\Windows\system32>ping myhost.mydomain Pinging myhost.mydomain [2002:1234:1234::1234:1234] with 32 bytes of data: General failure. General failure. General failure. General failure. Ping statistics for 2002:1234:1234::1234:1234: Packets: Sent = 4, Received = 0, Lost = 4 (100% loss), I can't get a packet capture of this behaviour. Running this (failing) ping command does not produce any packets in Microsoft Network Monitor. Similarly, attempting a connection with mstsc.exe to a host with an AAAA record produces no traffic until it does a fallback to IPv4. UPDATE: Our hosts are all using publicly-routable IPv4 addresses. I think this problem might come down to a broken 6to4 configuration. 6to4 behaves differently on hosts with public IP addresses vs RFC1918 addresses. UPDATE: There is definitely something fishy with 6to4 on my network. When I disable 6to4 on the Windows client, connections resolve instantly. netsh int ipv6 6to4 set state disabled But as @joeqwerty says, this only masks the problem. I'm still trying to find out why IPv6 communication on our network is completely non-working.

  • Windows SBS 2011 DNS Role (service) failing & needing restarting

    - by HaydnWVN
    Have a Windows SBS 2011 with Exchange that is handling all DNS for the network. Since getting a 3rd party (Hardware & Support) to setup a recieving FTP service and restricting Exchanges memory useage for another 3rd party product (Stock software) the local network seems to periodically 'lose the internet connection'. Delving deeper I found that the DNS service is somehow failing/stopping without the actual service on the server reporting such (nothing in event logs). A simple restart of the 'DNS Role' on the server solves the problem. The manager onsite reports that he has to do this most days in the afternoon - yet not at the same time and other days it works fine without a restart being required. I'm unable (lacking sufficient SBS2011 knowledge) to diagnose this further, ideally I would like the DNS Role to report (and log) the failure, then automatically restart itself.

  • Name Servers changed over 48 hrs ago and site is still down

    - by Solomon Closson
    Ok, I just recently changed Name Servers for my site (Oct. 29th): http://dream-portal.net but there is an issue, the name servers were changed from godaddy, however, the DNS is being hosted elsewhere. Godaddy states that the DNS is resolving the site to www.dream-portal.net and that is making it inaccessible from the DNS on the other host and that they can't do anything because I'm not hosting DNS with godaddy. I've contacted the other host and they say that everything is fine, however, people are not able to access the site and I can't access it from my work computer. I can only access it from my home computer. From my work computer it says that the page can not be found. What should I do? What can I do? Other people reported problems with the site here: http://www.simplemachines.org/community/index.php?topic=487592.msg3629960#msg3629960

  • Add a subdomain that is hosted elsewhere

    - by Martin Wiboe
    Hi, I am quite inexperienced with DNS, so this might be simple. Our main domain foo.com is hosted at provider A. Now, we would like to host bar.foo.com at some other provider B - they have the domain set up with them, so I figure that I can do this by somehow adding the nameserver at provider B to the DNS configuration at provider A. The current DNS config is as follows: http://imgur.com/kG099.png How can I add the new subdomain to this configuration? Regards, Martin Wiboe

Any problem ? Thanks for reading this :)

  • Issue with www to non www redirect

    - by bob
    Hello, I am on slicehost and I followed the articles that they gave for DNS redirection and the www to non www url redirection does work. However, what if I want a www.domain.com to be the default domain. Would I put www.domain.com. as my DNS record name or would I keep domain.com. as my DNS record and then do something else. Basically, what happens is if someone goes to the url www.domain.com/directory/something.html they will be redirected to domain.com and not domain.com/directory/something.html I would like the second thing to happen, not just go to domain.com and call it a day. I am running nginx and am confounded on how to solve this issue. I'm not sure whether its an nginx issue or a dns issue. Any help would be greatly appreciated!

  • Removing forward lookup zone broke our site - why?

    - by user102469
    I'm fairly new to the job and trying to get to grips with the infrastructure here. We've moved a site from being locally hosted on our own network to an external host (1&1). I've transferred the DNS hosting from the previous DNS host to 1&1 to keep things simple. Once everything had gone through, visitors that were external to our network were being directed to the new site on 1&1 but requests from within our network were still going to our own server. I noticed in the DNS server that there was a forward lookup zone for the site pointing to our own server still. My (admittedly simplistic) understanding was that pausing that zone would then cause the DNS server to get the address for the site from our external DNS servers and our users would start landing on our new site. However, what happened instead was that they were being met with "page not found" type errors. I've resolved it my modifying the forward lookup zone A record to point to the external web server but would like to get an understanding as to why pausing the zone didn't work. Would deleting the zone work? I am reluctant to try that as creating it again will not be as easy as simply pressing "start". Many thanks.
