WRT160n local hosts in DNS

I'm wondering if it's possible to have local hosts added to the DNS. As in, when a host connects and gets an IP assigned using DHCP, it advertises its hostname to the router. It would be nice if that same hostname resolved to an IP, since the router is a DNS server.
For example, if I connect to computers named "sleepy" and "dopey" to the router, it would be nice if I could visit http://sleepy from dopey.
For a while, I had DD-WRT installed, and it had this feature (as have a number of other routers I've used), but it looks like the factory firmware doesn't support it. Am I missing something?
(I removed DD-WRT because, while it had some nice features, it crashed fairly often on large Wireless-N transfers.)

The Router offers a Dynamic Domain Name System (DDNS) feature. DDNS lets you assign a fixed host and domain name to a dynamic Internet IP address. It is useful when you are hosting your own website, FTP server, or other server behind the Router.

Do I have to locally host my DNS Server to have iCal Services work?

I have my registrar handling my DNS hosting and have set up an A record for what I'm putting into my "Host Name" field in the iCal Service setting. Is this correct? The error dialog that pops up is:
"No virtual host found for iCal service
More information about configuring the iCal Service and connecting this server to a directory server can be found in the Help menu."
The Help menu is useless. Where do I set up the "virtual host"? The only other place I've been setting up virtual hosts is in the Mail service. Do they overlap?
Oh, and when I try to enable calendaring in WGW, the check doesn't stay enabled. Any thoughts there?

Hi
A hostname or Fully Qualified Domain Name or FQDN (which I'm guessing you have heard of before?) generally looks something like this:
myservername,mydomain.com
You could substitute myservername for something simple like server or ns1 or xserve or osxserver. It can be anything you like. Clearly mydomain is whatever domain name you chose or have. This could be your real world domain or if you are only concerned with providing an internal service then a fictitious one will do. The .com bit can be anything you like. It does not have to be a real world top level domain (TLD). It too can be fictitious. Lots of people use .internal, .lan, .private even .earth or the town or city name of your location. You can even use .local if you like although I would steer clear of this as it can cause problems for the unwary.
Why give yourself problems when there is no need to? The point is if you use something fictitious it just has to look like a real world domain. As you can see if you decided that you only want this to be a private server behind NAT/Firewall then your hostname could look something like this:
server.newyork.here
I'm using New York as an example. You can also regard the above as the fqdn of your server. In the DNS Service you can add CNAMES or Aliases for specific services you are interested in. Something like intranet or www for the Web Service and possibly ical or cal or calendar for the iCal Service. Your server would then resolve its IP Address to all of those names in addition to its server name. Something like this:
intranet.newyork.here
calendar.newyork.here
And so on. You can 'push' this information out to your client computers using the Server's DHCP Service. Client computers would then be using the Server to resolve their DNS as well. If all of their services are coming from the server then that would make logical sense. At the moment iCal works best if client computers are bound to the Open Directory Master (your server) and are using it for their DNS. Proper working of Open Directory absolutely requires internal DNS running somewhere. Either on the server itself or on another server elsewhere.
I'm not an expert by any means and this is all simply put but you should be getting an idea of what is required by now?
I posted something some time ago that 'walks' through how to set up from scratch your server, DNS and OD simply and concisely. If you are at an early stage or purely testing then perhaps you can give it a go and see if it works for you?

DNS or Local Host Name Issue

I have an iMac, 10.6.2 that continues to get a duplicate IP address error. I have determined that this iMac is seeing itself as another machine on the network, hence the duplicate IP error. I have changed the local host name under system preferences -->network (and in sharing) to imac10.6.2-username However, on the WINS tab of system preferences-->network the computer name shows as imac 9B14C4. I have manually changed this on the WINS tab and but it doesn't actually change it. I have flushed DNS and used the scutil--gethostname command to no avail. Additionally, this iMac does not show up when browsing the network from any machine on the network. All other Macs here do. Any suggestions?
Message was edited by: EricWeiner
Actually I can browse to it through the network by either the DNS name or the WINS name, even though I tried to make them the same.

I use a Mac mini as a small AV server, and have exactly the same issue. Message keeps popping up at least once a day. Changing name in Preferences doesn't make any difference. After a few weeks it's gone from 'Centerstage' to 'Centerstage-8'. I even formatted the HD and installed Leopard and after that Snow Leopard. Didn't solve anything. Very irritating. Apple only recognizes this as a Mac OS X server issue.
Help.

Cisco ASA 5505 Cannot ping local traffic and local hosts cannot get out

I have, what I believe to be, a simple issue - I must be missing something.
Site to Site VPN with Cisco ASA's. VPN is up, and remote hosts can ping the inside int of ASA (10.51.253.209).
There is a PC (10.51.253.210) plugged into e0/1.
I know the PC is configured correctly with Windows firewall tuned off.
The PC cannot get to the ouside world, and the ASA cannot ping 10.51.253.210.
I have seen this before, and I deleted VLAN 1, recreated it, and I could ping the local host without issue.
Basically, the VPN is up and running but PC 10.51.253.210 cannot get out.
Any ideas? Sanitized Config is below. Thanks !

Hi Martin,
Which way you are trying. Sending traffic via site to site is not working or traffic which you generate to outside world is not working?
But you say ASA connected interface to PC itself is not pinging that is strange. But try setting up the specific rules for the outgoing connection and check. Instead of not having any ACL.
If it is outside world the you may need to check on the NAT rules which is not correct.
If it is site to site then you may need to check few other things.
Please do rate for the helpful posts.

Event ID 1012 - There was an error while attempting to read the local hosts file

When I start my Computer after it has been turned off overnight (switched off at the Power supply) I get a Blue screen and have to reboot the PC. in the Event log it has this error: Event ID 1012 - DNS client events - There was an error while attempting
to read the local hosts file.
Once the PC has booted evrything is O.K. I can restart the PC with no problems, it only seems to happen if the PC has been switched off for a while.
I am connected to the net via an Netgear dg834v4 Modem/Router

Thank you

After further Investigation it seems that this error is Not responsible for my Blue screening......I started my PC after leaving it off all night, and it started normally, but i still have this error in the Event Log - System.....I have searched the Technet
forums (and there is a lot of ID 1012 errors) but non relating to my problem....If anyone knows what is causing this error and how to fix it, i'd be Grateful....although it does not seem to affect the PC in any way that i can see.
thanks

Since Windows system uses separated user mode and kernel mode memory space, stop errors are always caused by kernel portion components, such as a third-party device drivers, backup software or anti-virus services (buggy services).
The system goes to a BSOD because there is some exceptions happened in the kernel (either the device driver errors or the service errors), and Windows implements this mechanism: When it detects some errors occur in the kernel, it will kill the box in case
some more severe damage happens. Then we get a blue screen or the system reboots (it depends on what the system settings are).
To troubleshoot this kind of kernel crash issue, we need to debug the crashed system dump. Unfortunately, debugging is beyond what we can do in the forum. A suggestion would be to contact Microsoft Customer Service and Support (CSS) via telephone so that
a dedicated Support Professional can assist with your request. Please be advised that contacting phone support will be a charged call.
To obtain the phone numbers for specific technology request please take a look at the web site listed below:
Microsoft - Help and Support
If you are outside the US please see
Microsoft Worldwide Home for regional support phone numbers.
Meantime we can try some available steps as a general troubleshoot.
1. Please remove the antivirus and run the system with a period. If the issue does not occur, mainly focus on antivirus settings and compatibility.
2. Disable Automatic Restart and see detail information on the blue screen.
1).Click Start, in the Start Search box enter sysdm.cpl.
2).Click the tab Advanced. Under Startup and Recovery, click the Settings button.
3). Uncheck “Automatically restart”.
4). On the drop-down menu “Write debugging information”, choose “Small memory dump”.
5). Click OK.
When Blue Screen displays, you may find some useful information.

Simulate GSS in local host file

Hi,
I would like to test out the GSS without publishing it on the internet DNS.
So the only way I think is to update the local host file (Win XP). What would be an equivalent entry in local host file for the below in Internet DNS
abc.com IN NS gss.abc.com
gss.abc.com IN A 22.11.22.11
Mapping a domain/hostname to IP is straight foward, but how can an NS record be added.
Thanks.

Thanks. But I would like to avoid DNS effort and just manage with the local host file. So I would like to know whether it is possible to enter NS record in the local host file.
If I were to ask for hostname abc.com, the process should be
1. Check local host file for abc.com
2. abc.com is pointed to NS record in local host file.
3. The Name Server has a IP mapping in the local host file.
All of the above without any DNS setup. A local host file at the moment is like
abc.com 22.11.22.11
which I want to change to
abc.com IN NS gss1.abc.com
gss1.abc.com 22.11.22.10 (GSS IP)
How can I acheive 'abc.com IN NS gss1.abc.com' in local host file.

Handling Dyn DNS Active/Failover service while also hosting internal DNS

I want to try and take advantage of using Dyn DNS failover service for our websites, to where it will detect when our primary public IP address to webserver goes down and will automatically update the dns record to use our 2ndary public IP address in our
failover site. The only trouble i'm running into is we also host the domain name internally as well which we normally point to the private of the web server in our primary site. is there a way to just have the request for that one specific A record
to go to an external dns server to get resolved while the remaining records can be resolved internally by that server? tried round robin with the 2 ip's addresses but does not work as i need it to. Thanks any help is appreciated.
Michael Duhon

Hi,
According to your description, my understanding is that you want the customer to access the website by another public IP when the current public IP down: request for specific A record to go to an external DNS server to get resolved while the remaining records
can be resolved internally by that server.
Usually we can use DNS conditional forwarder to redirect the query for a specific domain name to another DNS server, but we can’t specific a DNS server for an A record query.
Or, you may try to manually add the record in local hosts file.

Eve Wang

Spamassassin Ignores Local Host Aliases?

wacondatrader.com is the primary domain for my server. I also have local host aliases for beloit-kansas.com, kvsvradio.com and plainstrader.com. My ISP has pointed his DNS records to my server and my user account "joe" receives email to all of these domains, as do all of my user accounts setup to use mail services.
I am running MacOS X 10.4.4 Server (just upgraded from 10.3.9).
I have Spamassassin and ClamAV running. Junk mail is being scored and filtered, but for wacondatrader.com ONLY. For email sent to any of the other domains, I am not getting any X-SPAM headers in the email to show that Spamassassin has been there. However, I am getting X-VIRUS headers on email to all of the domains. What do I have to do to get my Server's Spamassassin to process email for all of the domains, and not just the primary one?

If above fix works, none Did you try?
If not, the output of postconf -n would be a start.
Plus the settings you chose for content-filtering
(amavisd.conf is to big to post)
Also, did you have spamassassin on your Panther
install already or only since you updated to Tiger?
I tried your suggestion, but no success. Here is what I wrote on the MacOS X Server mailing list:
I have wacondatrader.com setup as my primary mail server in the general Mail Services settings pane. I also have several other domains that resolve to my server that I have setup in the Virtual Host Aliases in the Advanced Settings/Hosting panes. I recently upgraded from Server 10.3.9 to Server 10.4.4 and I did NOT have an existing Spamassassin/ClamAV installation. What is there is what the 10.4 installer placed there.
Is it the default install behavior for only the default domain to be tagged with the X-SPAM tags? I have in the amavisd log, compared an email to the default domain and one to a virtual hosted alias domain, and the log shows that amavis is scanning both for viruses (the X-Virus tags show up in all emails), and it even shows that all emails are being scanned for spam. The ONLY difference is that the log entry that says "SPAM-TAG . . ." is missing from the virtual host alias domains. The virtual host aliases domains even show that a hit count is being generated, so it looks like everything is being processed except the part that adds the spam tag headers to the email. The default domain emails are the only one that the spam tag headers are added to.
Do I need to assume that I need to modify the amavisd.conf file some how, or should Spamassassin be expected to scan the default domain and virtual host aliases in a default Tiger server install?
I tried the following advice from the Server discussions board at Apple's support area of their website (and also from similar instructions from this mailing list from about a month ago, that I found by searching the archives):
In a text editor open /etc/amavisd.conf
Search for the section that reads:
@localdomainsacl = ( ".$mydomain" );
below it add this line:
@localdomainsmaps = ( 1 );
Save.
Stop and Start Mail Services
I logged into my server locally with the root account, followed the above instructions, opened amavisd.conf in TextEdit, but the desired change did not happen.

Is there a way to run using local host ip (127.0.0.1)?

I am trying to get a working system at home. Obviously I cannot use a dialup
dynamic IP address, but is there a way to enable iAS 6.0 SP3 to use the
local host address of 127.0.0.1?
kas.exe complains 'value of admin host in registry is invalid (localhost IP
is not acceptable)'. I am running Windows 2000 and I do have a network card
that I sporadically use to connect a laptop. It appears that with Windows
2000, I can not use my Ethernet cards PI address unless I actually have it
connected to a network.
Any assistance would be appreciated.
Thanks,
Bret Hansen

Yes. Use the loopback adapter.

How to set up a JSP local host server?

I am trying to set up a local host JSP server, do you know any good youtube or tutorials in general that would help me set up a local host JSP server? Or could you post the steps here and your source (if any).
I am looking for something similar to XAMPP as in this youtube tutorial: http://ca.youtube.com/watch?v=KWRB-maTVyM&feature=rec-fresh However, any help would be greatly appreciated.
By the way, I am very new to JSP and was wondering, XAMPP includes Apache, is Apache a JSP server?

You need a Java web container to run JSP/Servlets. A commonly used one is Apache Tomcat. It is not the same as Apache HTTP Server which can only serve static files.
You can find Tomcat here: [http://tomcat.apache.org].
How to install/use it, just check the User Guide: [http://tomcat.apache.org/tomcat-6.0-doc/index.html].

Do I need to have my site uploaded to a remote host for embeded formscentral form to work? I am getting a broken section of header with a warning sign on top corner saying "!Local host." Cheers

Hey there all.
I am wondering if there is something wrong with my embedded form or if it is simply because
I have not uploaded my site to remote host yet? I am only getting a broken part of the header with
no actual form, with a warning "!local host" in top left hand corner. If anyone could enlighten
me on this problem it would be greatly appreciated, it is my first time making forms

Cheers, I noticed some browsers were treating the form differently. I am uploading to a test server tomorrow, hopefully all goes well, thanks for your reply

Error on invoking a webservice by giving ip address instead of local host

Hi,
I created a web service through jdeveloper and tried accessing the webservice generated WSDl file by giving ip address of my machine , but it throws me an error stating IE cannot display the web page . The same web service is running fine when giving local host on the Web service URL .
Looking frwd fr sme help
Thanks in advance
Ragaven

Hi,
your WebLogic server is not setup to listen for the IP address. You can change this in the WLS console for the server configuration. Note that when you install WLS and don't define any hostname then it will listen to all addresses (which also is the default for the integrated WLS)

How do I add a new IP to the local host file?

One of the sites I manage has been migrated to a dedicated server. Before changing the nameservers, I need to proof all the pages. To do so, I need to add the new IP number to my local computer local host file.
How is that done?
