Any idea what could be mis-configured.

I did a basic installation of Debian, which will be used for a mail server. I Installed the bind9 and did the configuration of the zones and created the files in the directory / etc / bind.
After the process I typed the following command to test my DNS:
nslookup mail.hotelpart.com and presented the following error:
Easier to stay I put my files in message: The files named.conf, db.hotelpart.com and db.111.20.11.200.

School with linux running on students' laptops, connecting via wlan to a Debian NFS and LDAP server. Every student logs on his/her profile residing on the NFS server.The clients are set up with autofs. Earlier, I had set up the wireless network in /etc/network/interfaces, but this time I decided to configure network manager so as to bring up both wireless and wired network before logon. This setup has been working on for the last fire or five years with only minor changes. Also worked with Karmic Koala, but still with the interfaces file instead of networkmanager. The Vostro is also new here, we've previously used mostly Dell Latitude D505s.
So here is what works:
1: Clients can log on to LDAP and NFS servers both wired and wirelessly. Everything is smooth.
2: While on LAN, shutdown and restart works flawlessly (and quick as a breeze, I'm really impressed by startup/restart/shutdown times, under 25 secs!).
3: Shutdown and restart also works wirelessly when doing it either from a local account or from the GDM chooser.
What doesn't work, however, is shutting down or restarting directly from a networked account connected while only being connected over the wireless network. This is what's being displayed on the terminal after it has tried tho shut down for a while:
Code:
The system is going down for halt NOW!
acpid: exiting
init: cron main process (1011) killed by TERM signal.
init: tty1 main process (1365) killed by TERM signal.
[code]...
If I try ctrl-alt-del at this stage, it says:
"init: rc main process (3030) killed by TERM signal"
"Checking for running unattended-upgrades: "
And then it will hang again, until I hold the powerbutton for some seconds. The unattended-upgrades part is what seems to be the culprit. I suspect it is about the wireless network not being connected any longer or something like that, but I'm not sure about how to go about debugging shutdown scripts here. I'd be grateful for pointers. I will try and see how it goes with the old interfaces file setup, but I'd rather make nm work.

I currently run Windows Server 2008 at my office, but I'm looking to test Samba as a PDC for future reference/consulting work. Before I go and try to configure Samba, I wanted to ask if anyone can think of pitfalls I would run into and perhaps recommend a better setup:
<10 PCs running either Windows XP, Vista, or 7.
VirtualBox running Debian (planning on swapping for Fedora) on a Windows XP Home computer.
Computers are connected to a large switch, which is connected to a wireless router. The Windows server doesn't employ ICS (essentially is just a $1500 PDC ). where I could find a .ovm format image of a windows server installation? I'm guessing vmware would work in this regard, but I'm not fond of using purposely crippled software.
I'm trying to design an inexpensive large scale DNS server but fail to find any metrics or methods to base scalabilty.Can anyone offer information on building a stable dedicated DNS server? That might be able to scale well.

There is server with 3 hdd mounted to /h1 /h3 /h4 and its a file server contain 3 TB of data (must of them are in zip or rar format), We need to move whole files to the new server.I need a command or bash file to show me the name of files in these partition and the patch of them in the txt log file. (So i can create the link and download all of them in new server with download manager).I tried rsync but its too slow...After we created the links of whole files we will deny all ip address exclude new server IP address in nginx then we can transfer them all fast. (The servers are in 1 datacenter.)

I have found that our development server which is RHEL 3 (also ClearCase client) hangs when user gives find command.After some time of execution of the find command the server hangs. We have to hard-boot the server.Is this the normal behaviour of the Servers? This server which I am talking about is highly used.Sometimes 120 or more terminals will be opened and few compilation will be happening in the server. And same single user some times opens multiple terminals and works simulataneously.We have been monitoring the server and found out that during the workdays CPU usage % goes very high.

View 14 Replies View RelatedI will be relocating to a permanent residence sometime in the next year or two. I've recently begun thinking about the best way to implement a home-based network. It occurred to me that the most elegant solution might be the use of VM technology to eliminate as much hardware and wiring as possible.My thinking is this: Install a multi-core system and configure it to run several VMs, one each for a firewall, a caching proxy server, a mail server, a web server. Additionally, I would like to run 2-4 VMs as remote (RDP)workstations, using diskless workstations to boot the VMs over powerline ethernet.The latest powerline technology (available later this year) will allow multiple devices on a residential circuit operating at near gigabit speed, just like legacy wired networks.
In theory, the above would allow me to consolidate everything but the disklessworkstations on a single server and eliminate all wired (and wireless) connections except the broadband connection to the Internet and the cabling to the nearest power outlets. It appears technically possible, but I'm not sure about the various virtual connections among VMs. In theory, each VM should be able to communicate with the other as if it was on the same network via the server data bus, but what about setting up firewall zones? Any internal I/O bandwidth bottlenecks? Any other potential "gotchas", caveats, issues? (Other than the obvious requirement of having enough CPU and RAM).Any thoughts or observations welcome, especially if they are from real world experience in a VM environment. BTW--in case you're wondering why I'm posting here, it's because I run Debian on all my workstations/servers (running VirtualBox as a VM for Windows XP on one workstation).
I've been setting up NIS for the first time. When I have the firewall on, the NIS client can't find the NIS server. When the firewall is off, it can. These are both on the same computer (the server).I have both the NIS client and server opened in the firewall -- all the setup has been done through yast so far.
Is there something else that needs to be done that I missing? Or if not, perhaps it just a minor setup bug in the scripts in which case could someone tell me what ports I would additionally need to open manually in the firewall to make it work that wouldn't already be opened?
On a different note, in a recent discussion on another thread someone told me that openSUSE was going to be unsupported from around May this year -- has anyone heard of this or should I just ignore it? I thought with 40k users registered on the website Novell would find something better to do with all of us rather that just drop us so I am a little skeptical.
