When DNS server is configured on Windows server, it will automatically detect and catch computer names and IP address. With Linux (BIND), I have to enter each clients manual under zone file. example (computer1 IN A 10.10.1.4). is there anyway to make Linux detect client automatically as windows does?

However I just built a 10.10 server, installed webmin, vmware, and the server is working perfectly. I configured my bind 9 server using the latest webmin and on the server everything resolves perfectly to both the internet and lan. I have it set to 127.0.0.1, the server ip address is 10.1.50.25. However, it will not accept dns client queries in which they cannot resolve to the lan or internet. I have the dhcp giving out the dns server 10.1.50.25. NSLOOKUPS from the client show query refused. I know there has to be some setting or config that will allow clients to query but I am not able to locate it, and I am not totally knowledgeable of named.conf and been all through the webmin module and configuration settings.

View 1 Replies View RelatedI am writing a TCP server in C, and the server listens to incoming client connections and accepts them. It then creates a thread to handle the client. The clients are expected to only receive data from my server and not send any data. So if I use a select() call with a recv(), I believe that the recv() will just block forever since there will not be any data coming from the client. If I use a non-blocking recv(), then this will just return a 0 which tells me nothing because the client is not expected to send any data. I am not sure if I have misunderstood some socket concepts, but I need a solution to detect when the client has disconnected so that I can close the socket and stop sending data to the client. As I understand it, simple ACKs etc are not captured by the recv(), and only data sent by the client will cause recv() to return a non-zero value, so I am not sure how to know when the client has disconnected.

I've installed Ubuntu 10.04 server onto my former gaming system, Intel(R) Core(TM)2 Duo CPU E8400 @ 3.00GHz, 2 cores with 2 GB ram. Overkill I'm sure, especially for a simple personal voip, htpc, storage server.
The problem is only noticeable when I have the vent server running, on the 10.04 server, and I attempt to connect to it through the LAN via the client on my windows computerEverything works fine and connects, LAN and from the outside, as long as the server is set to DHCP. However when attempting to switch to a static IP address, the vent client will not detect the vent server at all.Aside from an annoyance at having to stick with DHCP, I am still curious as to why the static settings will not function. Something so simple has turned into something quite difficult.
I can still connect to the Webmin interface and Putty into server with either DHCP or static IP enabled.I've performed the following troubleshooting steps so far:1) Followed the directions at https://help.ubuntu.com/8.04/serverg...iguration.html2) Edited the /etc/network/interfaces file through the CLI with nano and through notepad on the windows computer3) Through Webmin I've assigned the static IP, although for some reason it does not include a gateway field.4) I've rebooted the server5) I've issued the CLI
Code:
sudo /etc/init.d/networking restart

I'm trying to get BIND running on one of our Fedora 10 servers, since we've had some issues with the DNS from our service provider. This BIND server is not authoritative for any domain, it's merely for caching purposes. I used the sample DNS file at [URL].., and modified it slightly with our internal IP addresses.
I'm getting the following errors when I do service named start:
Error in named configuration:
zone localhost/IN: loading from master file master.localhost failed: file not found
_default/localhost/in: file not found
zone 0.0.127.in-addr.arpa/IN: loading from master file localhost.rev failed: file not found

I am working on fedora 10 and configured dns on my college lan which already has it's dns at 192.168.5.20 .So i configured my private dns server at 192.168.101.91 which is my ip too.And the domain name is the host name of my system for example server.onkie.com.MY dns port 53 is shown when i do nmap localhost but but doesnt show when i do nmap 192.168.101.91 .Also when tested my server on other computers on my lan with there primary dns as 192.168.5.20 and secondary as 192.168.101.91 they cant access my site at my system with the name [URL].. . nmap localhost

I already disabled my selinux and iptables ..but then also it's not accessible in Lan .
I have a Fedora 11 Server which act like a Internet gateway for our LAN. I have my own iptables andt squid. We daily starts up & shuts down the server. Since last few days I am facing a unique problem. When we starts the server we are able to brows the Internet on the Server but from the client machine we are unable to do so but we can ping any internet sites/Static IP from the Client machines. After 2-5 times of startup and shutdown of the Server. We are able to browse internet from the client machine.
View 2 Replies View RelatedI'm thinking about installing a DNS server on Fedora 13 running bind. I looked around for available bind packages and found only these:
Now the first one contains bind utils the second one is for running DNS in a chroot env and the last one is a bind with some DB backend.
Does this mean that fedora 13 doesn't support/.provide "standard" bind server (I mean the one to run without chroot/without db backend) ? Or am I missing anything in my repolist which is :
anyone come across a mysql driver for Bind that is already in RPM format? I know there is one that you can compile, but i was just curious if anyone knew of a MAINTAINED package that does that same thing?
==Edit== While i'm at it, does anyone know of a way to have bind call a STORED PROCEDURE, instead of directly querying a table? That'd be sweet. --Or, even having bind query a php file, or a webhost, would be good... I'm going to google that one now....

I can't get the client server to authenticate to the openldap server. I can authenticate on the server itself though. I can su to, login and shh into the openldap server and become a ldap user. I just can't become an ldap user on the client.I didn't setup TLS/SSL. I can do that after I have it working. I'm using hashed passwords though. I don't have replication setup. I'm am tying to setup the most basic openldap environment then build from there. I have read the openldap section in the admin guide.

I am an administrator of a student lab with 20 PCs. I was thinking of a way to protect those machines in the long run with the presence of some students with destructive behaviour. The most suitable solution to install a Linux OS and use virtual machines to load Microsoft OS. This way once the OS fails I can simply replace the VM with a clone that was previously made.
The point is that most students have no experience with Linux, that's why I need to load the Virtual machine automatically at login and in full-screen view so that The startup process ends up in Microsoft OS through the virtual machine (VMWare based) in Linux platform.
update : I'm using Fedora13 Linux distribution. I believe that part of launching the VM in full-screen is more difficult than automatically launching VMWare at startup. Is there some way I can tell VMWare to launch a particular virtual machine in full-screen when it starts on boot?

I am having trouble getting grub to automatically boot into ubuntu server. When I turn on my server the grub menu shows up and shows me the choices. They all work fine except that grub wont automatically select one. This wouldn't be too much of a problem but this is a headless server and I can't boot into ubuntu without a keyboard. I tried looking through the grub 2 documentation but nothing seemed to work when I edited the conf file.
View 1 Replies View RelatedEver since I switched from windows I miss the fact that gaming is not all that well on linux. I think that is pretty unfortunate. The games I'd like to play are team fortress 2 and a bit of civilization 4. Luckily for me, these games are known to run good through wine. But the bad thing for me is that I had an old ATI card and I was stuck with the bad driver that caused all these games to crash. So I had it with this. Each time I wanted to play I needed to restart to windows. So I saved some money and yesterday I bought a geforce 640 GTX.
When I boot up the computer for the first time with my card it all seems to work well. It just did not detect my new card automatically. And now I have to confess I'm not all that experienced with ubuntu and getting some things done. But I thought, ah well.. 10.10 is coming up, lets update to the release candidate and see how things are going from there. A new card and new version of ubuntu, woohoo! Now after the update it did detect the driver and it seems to run pretty well, but I do have a few problems.
I have a small second screen to extend my primary desktop. In the NVIDIA X Server Settings and under the tab 'X Server Display Configuration' I have the second screen in 'TwinView' and it seems to work well. Untill I restart my screen that is. After a restart I have to keep activating my second screen. I was kind of hoping it'd save the settings.
The other problem is what I get when playing team fortress 2. I'm not sure this is the right place to ask here, or I should better head to the wine forums or something, but I do hope to fix this. When I have the second screen enabled, and I'd like to start team fortress 2 it gives a warning: 'Failed to create D3D devide'. Doing some googling, it seems to be a resolution problem. After I disable the second screen, it works again.
Then with the second screen disabled it seems to finally run. But unfortunately after 5/10 min the I get kicked out of the server with the message 'Disconnected: Client timed out'. I did some googling arond and there's not much results relating to wine/ubuntu, but most windows users seem to have this problem because of a firewall. Now, I'm using ubuntu and not using a firewall as far as I know (there's probably some build in, I just take that as it is ). But maybe anyone here knows how to fix this and I do get to finally play team fortress 2 on ubuntu?
