I'm having really weird and frustrating DNS issues with my clients unable to properly resolve the server's ip address. They can resolve each other's, and outside systems, but not the server - at least, not correctly, and not all the time.
I have one Ubuntu server set up that does both DHCP and DNS serving to the Windows systems. The server has DNS forwarding turned on to forward to OpenDNS's servers (I've tried using my ISP's dns servers but the problem remains).
The server is *not* set up as a firewall; I am actually using a DLink router for that, and the Dlink is *not* set up to serve up DHCP nor DNS.
What I am getting is that my clients - and there are nothing but Windows clients - will not resolve the name of the server. For example, if I do: ping linuxserver
I get back a false IP address of 192.168.0.64 (and I've seen once a 192.168.2.49).
If, however, I put a dot in there: ping linuxserver.
I get back the *correct* IP address of 192.168.0.2, and thereafter, ping'ng linuxserver without the dot will work. Until the dns cache expires, either naturally or with ipconfig /flushdns on the windows clients.
The client *are* getting valid dhcp leases and can resolve everything happy-happy, they just will not get the proper address of the server 100% of the time.
I just installed DarwinStreamingServer. All seems normal in admin panel But everytime I try to play the file using QTime player...the play button quickly turn into "Play" again as I push it. Then I try to open it via my nokia phone, I got message "Disconnected" as soon as it connected to the server.
View 1 Replies View RelatedI have an internal domain (dev.lan) for which my Ubuntu server is authoritative. We have a number of subdomains under that domain (test.dev.lan, svn.dev.lan, etc.). The server also acts as the primary DNS server for my office. It was originally set up under Ubuntu 8 and worked great.
However, ever since we upgraded to Ubuntu 10, our Windows clients periodically lose the ability to resolve domains on the dev.lan domain. Internal IP addresses can still be pinged from the Windows machines so it does not appear to be a network-connectivity issue. External domain names continue to resolve without any problems. The only workaround is to restart networking on the Windows clients. It's frustrating because it happens several times a day.

I have a server (called NAS) that shares out /public, and I also have this same server running KVM with some VM's. I am setting up the first VM now, and one of the things it does is download torrents onto the share. I am connecting it via "mount -t smbfs //nas/public /mnt/nas" from the VM on the host and it seems to work fine. However whenever I add a torrent to the queue on the VM to download, all downloads stop and seem to be disconnected. I can restart them after a few seconds, but they will stop after a few minutes with another disconnect error. I have the network interface bridged, so I thought it was talking directly to the host.
The appropriate lines in my smb.conf:
security = share
[public]
comment = Public Stuff
path = /public

I've a fully working openvpn network but it works only using ip address.Clients should comunicate each other thought the server. To semplify the managment of clients I'd like to use their hostname instead their ip. there are a way to achieve it?Now openvpn assign ip address to the clients, but if is needed I can install other software on the server, it's a Debian machine.
View 4 Replies View RelatedI have a windows and a linux box running DHCP respectively. The problem is whenever my client system boots up, it fetches the dynamic IP from the windows box. What should I do in order for my Linux box to provide dynamic IP's to clients? Both servers are in a single network. connected via switch.
View 1 Replies View RelatedI'm having problems with my Internet. I just recently downloaded 10.04 (went from 8.04) and now I can't get online! I could yesterday! I don't have access to the router, but the internet works great on all my Windows computers. On my panel it show's my wireless connection bars with an exclamation mark and says disconnected. I don't know what to do! It's a Toshiba Satellite computer.
Also, I can't update anything, or install anything because I don't have direct access to the router. I know there is a lot of information about this problem already, but everything I've seen needs me to download new drivers. If you know how to do it from one computer to another I can do that. I'm just not very techy.
This morning I connected to internet, using the 'hidden network' feature of Ubuntu, like I always do. In the beginning it worked well, but after a while, while playing a game, I got disconnected. As I closed this game, I discovered that Ubuntu was asking for the WPA key (it was already filled out correctly) There were no changes made in the network while I was playing. My brother and his girlfriend can both connect using their Windows 7 laptops, so the network itself should be allright.

View 3 Replies View RelatedIm using Ubuntu netbook remix on my wife's hp mini. Ever since I switched my router out this netbook will connect to my wireless network, then show a disconnected icon, yet the internet still seems to work. I've searched around and seen that other people have had this issue but I haven't seen anything on how to resolve it.
View 3 Replies View RelatedI'm having network problems and I have no idea how to fix it. At first, my internet connection was suffering on all computers on my network (Mac, Windows and Ubuntu 11,04). So, I disconnected my cable-modem and then reconnected. Nothing.... So, I rebooted my Windows machine and the internet came back on that computer.
I then went to my Ubuntu computer and clicked on "auto eth0" (per the way I interpreted instructions from the internet). The symbol turned from the "two arrows" to what looks like a wireless, looking for a signal. I thought that maybe I should just reboot, as I did with Windows. However, when I did reboot, that same wireless symbol was there, then a message came up saying:
Code:
Wired Network: You are now disconnected
I can't seem to get my internet connection back on my Ubuntu computer, though it is working on every other computer on my network.
I recently installed Ubuntu. I just installed ndiswrapper so I could install my wireless PCI [COLOR=blue ! important][COLOR=blue ! important]card [COLOR=blue ! important]drivers[/COLOR][/COLOR][/COLOR]
I did that and it is recognized and so is the network I want to connect to. But for some reason, it just wont connect. It will spend a long time trying to connect, but then just says "disconnected". It's not like I have a bad connection or anything. My internet on Windows is fast.
Since I have started to use Ubuntu 9.10, I have had multiple wireless connection troubles. First of all, it says the signal is 2 bars, when in fact my router is right next to me as of right now. Second of all, when I try to connect to it, it asks for my password 3 times, then says disconnected. I'm on a hardwire right now, it's across my keyboard, and I'm in a tangled mess.
View 2 Replies View RelatedI'm running Ubuntu Karmic Server with Xfce desktop, the problem is the network manager, it says it is disconnected, even though I am connected to my network and getting an internet connection. It wouldn't normally bother me, but I'm trying to setup a VPN using the network-manager-openvpn plugin. I put in the required details for the VPN connection, but as soon as I tick the "apply to all users" box, the information is lost. The information will remain if I don't tick that box, but it will not connect. when I try to select the VPN connection I just setup, nothing happens.
I've tried the exact same configuration on another desktop, running Ubuntu Karmic with Gnome desktop, the network manager works fine, my ethernet connection is showing as connected, and I can connect to the VPN no problem, the problem lies with the network manager in Xfce. Is there anyway I can get it to show as connected? it wont allow me to connect to the VPN otherwise, it's silly, because that adapter has a full working network connection.
Ive installed 10.04 on my laptop and notebook. It works perfectly on laptop. On notebook the problem is it finds no Wireless network and just says disconnected.

View 7 Replies View RelatedI installed xubunto 10.4 on my pc the other day and every thing was working fine and then the next day my wired network card went down. So I restarted it and it say Wired Network Disconnected. I tried doing sudo ifconfig eht0 up to try and bring the card back online but nothing happens. I also tried reinstalling xubuntu on my computer. Again my internet works then starts freezing up so I restart it and my ethernet card goes down again. I have tried also plugging it into the second ether net port on my computer but that does not seem to work. Also I went into my dhclient-script and went to the bottom to look at my network card stuff.
It reads

I tuned on my netbook and my wireless signal had a red exclamation.

Wireless Networks shows disconnected
I don't get it. Can't seem to get it to connect? How? If I open the connection information I can see the wifi networks around me. And edit/add/delete. But when I go back to the signal and click. it just shows wireless network disconnected and no option to connect. What to do? I have restarted the computer, router, cable modem, etc. Done the updates.
i used to download files using transmission bit torrent client. I download the torrent and once the download starts i will leave the system and check only after 4 or 5 hours later.But when i check the system again, the network connections were automatically disconnected.The download is getting stopped naturally. why my wired network connection is getting disconnected automatically if the system is idle?(ubuntu 10.10)

Don't know what other information I should provide. I tried a few things from different posts like editing the dhcpclient.config but don't really know what I'm doing and none of these worked anyways. I'm not even sure if they were solutions to a similar problem! I'm using the same connection on my Mac OS 10.4.11 (different machine) and I have no problems. Could I use these same settiings in Ubuntu? I don't know what the different fields represent or what I should input in manual settings.

I'm trying to set up my cell so I can use cellular internet in ubuntu like I do in windows.
