Is it possible to make a linux virtual machine appear as the host machine to a network tool like nmap or Blue's Port Scanner without recompiling the kernel?
If a Red Hat or other Linux host has a conflict with an IP address, is there a way to have it display a warning message on the console or in a log, like Windows and MacOS do?
i.e. my computer has an IP address configured (or received from a DHCP server) but finds another device on the network using the assigned address. Will it log the conflict?
I would like to find a way to open a url without using a web browser making my computer system runs very slow. Is there an easy way to achieve this on a command prompt using ssh to access another network? Thanks in advance!
I have a Linux server on my local network that is set up to use wakeup on lan. I copied this script verbatim, just replacing the MAC address in the example use. When I run this script on a Mac, the server wakes up. When I run it from Windows 7 (32-bit Ultimate) it doesn't do anything (note that the script DOES run, I added a debug raw_input() to confirm).
I'm using Win 7's built-in VPN client but every time I put my computer to sleep / hibernate mode and then wake it up again, the connection is lost and I need to reconnect manually. Is there any way to automate it? Wireless connections have a nice little checkbox ("automatically connect when this network is in range") but I couldn't find anything similar for VPN connections. Task scheduler maybe?
I have a linux (CentOS 5.2) server with the name myserver.mycompnay.com, which is correctly returned when I run 'hostname'. When I run 'hostname -s' however it returns "localhost" which is causing some backup scripts to put stuff in a "localhost" directory instead of a "myserver" directory.
All of our other CentOS boxes correctly return the first part of their hostname when 'hostname -s', where do I go on this server to make it behave the same? Other than having "HOSTNAME=myserver.mycompnay.com" in /etc/sysconfig/network what should I be looking at?
Is it possible to use a single port for SSTP and an IIS website, or will I be required to set up separate ports? I've got Server 2008 R2, and I tried doing it but now I can't get IIS to serve anything out of 443 even with RRAS uninstalled.
This is for a small home network, and I ideally want to open up just port 443 on the router and nothing else..
Any suggestions?

I am looking for a program or program suite that will allow the auditing of network shared resources (specifically storage space), and render reports (who created, deleted, moved, modified files, etc).
Yes, I know I can turn on auditing on Windows, but the Event Log isn't quite the "charmer" for the job.
I have an exchange sever 2003 installed and working. I have a new exchange 2007 server on another network. The two networks are completely separate with no connection. How can I take the 2003 mailboxes and put them on the new 2007 system? The move mailbox normal option on 2007 will not be able to see the old 2003 exchange server.
I was hoping I could just copy the database and mount it, but this doesnot seem to work.
Thanks
Is there a way to integrate an LDAP authentication system on a windows network with intranet webapps so that the user on logging into their desktop does not need to log in a second time with the web app?
Open to other forms of authenticating other than LDAP if not possible.
I'm on Fedora 14, and OpenOffice 3.3.0 takes a long time to open (about 30 seconds, sometimes less). It isn't a CPU or disk performance issue, it's just simply a very long delay before the program opens. It appears to be a frivolous network connection timing out.
According to Wireshark, it tries to look up:
dulcimer.(none)
which fails, after which it tries to look up:
dulcimer.(none).mylitestream.com
(dulcimer is my hostname, and LiteStream is my ISP)
Is there a way to work around this bug in OpenOffice?
I am the guy that was closest to the server :( and am actually a developer. I am getting this error, There are currently no logon servers available to service the logon request, when a machine on the domain is trying to be accessed from other machines from the network. Accessing other machines from this machine works as expected.
How should I go about to fix this?
We are running a Windows Server 2003 and XP Pro clients.
I'm thinking of using ZFS for my home-made NAS array. I would have 4 HDDs in raidz on a Ubuntu Server 10.04 machine.
I'd like to use the snapshot capability and dedup when storing data. I'm not so much concerned about the speed, since the machine is accessed via N wireless network and that is probably going to be the bottleneck.
So does anyone have any practical experience with zfs-fuse 0.6.9 on such (or simillar) configuration?
I have never used a Linux system in an AD environment before and am trying to join my laptop running Ubuntu to join our Active Directory (DC is a Windows Server 2008 machine) using Likewise-open.
Using the GUI wizard, I have joined the domain.
I can mount network shares using CIFS
Problem: I only have read access to our fileserver. What more is needed to get the AD to recognize me as a user who has the appropriate rights?
Any help is appreciated.
NAT uses IP address port number combination to hash the outgoing requests. Since ping requests consist of ICMP echo request packets they do not have any associated port number. How does a NAT server forward the replies to the hosts inside the network?
I got that message and i dont know what it is means:

Any idea what can be the cause of it ?
In many Windows programs when I open a file, the GUI dialogue that starts with "Look in:" and provides a list of directories and files to open has a thin panel on the left-hand side with the following 5 icons:
Recent Places
Desktop
Libraries
Computer
Network
Is there a Registry Hack available for adding my own icons to this? I wish to add three for various folders related to the work that I do, and I haven't been able to find a way to customize this.
Thanks in advance.
I need to cross-reference data involving a large number of IP addresses against known public proxies, spam-listed IPs etc. For obvious performance and network load reasons, obtaining a regularly updated dump for off-line processing would be preferrable. I currently use http://www.dnsbl.manitu.net/download/nixspam-ip.dump.gz - a digest of ix.dnsbl.manitu.net with 40,000 entries updated every 15 minutes. I'd like something more substantial though, so my question is: does such a thing exist?
I've been chasing a packet-loss and network stability issue for a handful of end-users on an internal network for the past few days... These issues surfaced last week, however the location was struck by lightning six weeks ago.
I was seeing 5-10% packet loss between a stack of four Cisco 2960's and several PC's and phones on the other side of a 77-meter run. The PC's were run inline with the phones over a trunked link (switchport configuration pastebin). We were seeing dropped calls and interruptions in client-server applications and Microsoft Exchange connectivity.
I tried the usual troubleshooting steps remotely, having a local technician do the following during breaks in user and production activity:
change cables between the wall jack and device.
change patch cables between the patch panel and switch port(s).
try different switch ports within the 2960 stack.
change end-user devices with known-good equipment (new phones, different PC's).
clear switch port interface counters and monitor incrementing errors closely. (Pastebin output of sh int)
Pored over the device logs and Observium RRD graphs. No link up/down issues from the switch side.
change power strips on the end-user side.
test cable runs from the Cisco 2960 using test cable-diagnostics tdr int Gi4/0/9 (clean)*
test cable runs with a Tripp-Lite cable tester. (clean)
run diagnostics on the switch stack members. (clean)
In the end, it took three changes of switch ports to find a stable solution. The only logical conclusion is that a few Cisco 2960 switch ports are bad or flaky... Not dead, but not consistent in behavior either. I'm not used to seeing individual ports die in this manner.
What else can I test or check to determine if these devices are bad?
Is it common for single ports to have problems, rather than a contiguous bank of ports?
BTW - show cable-diagnostics tdr int Gi4/0/14 is very cool...

How can I tell a Windows 2003 R2 server, which has multiple NICs, "listen for DHCP requests on NIC #1, ignore DHCP requests on NIC#2" ? The server is in a gateway role, connecting two networks, and I don't understand how to get it to be a DHCP server only for the "downstream" network.
In Win7 when you connect to a new network you're prompted to set it as a Home, Work, or Public connection. Presumably this influences default security settings.
That's all well and good, except for the part that everytime I USB tether my smartphone Win7 comes up with a new dialogue. I think I'm up to generic connection 25 or something? It's getting ridiculous.
Is there anyway to get Win7 to remember the phone tether as ONE connection only?
I have setup a Fedora 13 minimum install inside of a VirtualBox VM, and am following this tutorial to setup Cobbler:
PXE virtual network with Virtualbox and Cobbler
When I go to run the initial cobbler sync the command seems hang. How long should it take to run this command? Since I did a minimum install of Fedora 13 am I missing a application that would prevent cobbler from executing the sync properly?
From time to time, OS X (10.6) will ask me if I want to perform a backup of my Macintosh HD, but the backup destination is obviously the HD itself. I have not plugged in any external device, nor is there a Time Capsule network share.
A message like this will appear:
Moreover, the Macintosh HD will suddenly have a Time Machine icon in Finder. Has somebody experienced the same and could help me identify how to stop OS X from using its own disk as the backup destination?
I'm having trouble connecting to a MySQL database on the other machine on the same network.
