• VPN Configuration

  - by Josh

  How can I allow incoming connections on a Windows 7 machine that is connected to VPN? I have some services listening on certain ports that I have forwarded from my router. When the VPN is disconnected, I can connect to these services from my internal network as well as from the Internet without issue. When I connect my VPN however, I am still able to access the ports from my internal network, but not remotely. I think I need a split tunnel setup, and there is an option in the VPN settings to Use Default Gateway on remote network. I want this option enabled so all my traffic is routed through the VPN, but I want incoming connections to be allowed on my internal network IP from the Internet. Is there some hybrid way to set this up with routing?

• Can ping/nmap server, nothing else

  - by lowgain

  I was SSHed into our ubuntu LAMP server , and was just doing a svn update, which hung. I disconnected, and since then, I have not been able to SSH in or view any of our websites (neither from my network or through a remote machine). I would have just assumed the server went down, but I can ping the machine and get really quick responses. Using nmap on the box shows all the normal ports open, so I am confused This server is hosted remotely in a datacenter, do I have any remaining options except contacting them for support? Thanks!

• Can I associate my spare Elastic IP addresses to an Amazon EC2 instance started in an Autoscale group and Monitoring?

  - by undefined

  I want to know if I can reserve a number of Amazon Elastic IP addresses and assign them to instances started by Autoscale. So basically, when a new instance is started because a trigger has been triggered can I also set the API to look for a spare IP address and allocate it to the instance. I need to do this because the started instance will need to communicate to a server outside the cloud and get through a firewall which will only allow remote access from a predefined set of IP addresses. So i think i need to reserve some IPs, add them to my firewall settings then allocate them (automatically) when a new instance is started. Any ideas?

• Color highlights have vanished in emacs

  - by Jim Kiley

  I'm using emacs on a remote Linux server that I access via ssh. I'm editing C files that have a non-standard suffix, so I have had to manually enter c-mode with M-x c-mode every time I open one of those files. I found this to be annoying so I started monkeying with my .emacs to make that problem go away. This made all the color highlights in c-mode go away instead. Correction: All my color highlights are gone. I've removed the .emacs file, logged out and logged back in, but now, the color highlights are gone. I miss them! They were very helpful How do I get them back?

• How to keep TightVNC client on Windows XP alive when connected to OS X?

  - by craibuc

  I'm using TightVNC on my Windows XP workstations to connect to a remote OS X box (10.5.x) using OS X's VNC support. I've noticed that the TightVNC will become unresponsive after a period of inactivity. Is this a common issue? Restarting TightVNC solves the problem, but can be a bit annoying. Is there a solution to this? I don't suppose copy & paste between the two systems can be made to work?

• VMWare hypervisor with only 1 network card?

  - by Rafiq Maniar

  VMWare hypervisor minimum requirements states that the minimum network requirements is: one NIC, plus one for Management interface (source: http://www.vmware.com/products/datacenter-virtualization/vsphere-hypervisor/requirements.html) It used to be possible to use 1 NIC only. Is anybody using the new versions of VMWare in this configuration? I ask because my colo provider will only provide me with 1 uplink (my server does have 2 NICs). I need to be able to run the VMs and also have remote management using only 1 NIC. Possible?

• Tool to launch a script driven by modem activity

  - by Will M

  Can anyone suggest a software tool (preferably under Windows XP or later) that would launch an application or script in response to a phone call being received on a landline phone line connected to a data modem on the same PC? or, better, in response to a sequence of touch-tones being played over such a phone line. This would allow, for example, using the telephone to manipulate firewall settings so as to create another layer of security in connection with remote internet access to that computer. I seem to recall seeing tools to do this sort of thing in the days before broadband internet access, when there was more attention to various tips and tricks for the dial-up modem, but a few attempts at Google hasn't turned anything up.

• Why has my Mac been running fsck_hfs for two days now?

  - by Nate

  I first noticed that fsck_hfs was running, taking up 50-75% of a CPU, yesterday. It continues to run today. ps shows that it is doing /sbin/fsck_hfs -f -n -x -E /dev/disk3. Only problem: I don’t think I have a /dev/disk3. Why is it running? Will it ever finish? Can I kill it? What is /dev/disk3? Could it be my Time Machine volume, which is not mounted at the moment? System Info: MacBook Pro (2008). It has two disks installed—the internal disk (/dev/disk1) and a PC Card SSD (/dev/disk0, surprisingly). It connects to a remote Time Machine volume attached to an Airport Extreme base station.

• Files copying between servers by creation time

  - by driftux

  My bash scripting knowledge is very weak that's why I'm asking help here. What is the most effective bash script according to performance to find and copy files from one LINUX server to another using specifications described below. I need to get a bash script which finds only new files created in server A in directories with name "Z" between interval from 0 to 10 minutes ago. Then transfer them to server B. I think it can be done by formatting a query and executing it for each founded new file "scp /X/Y.../Z/file root@hostname:/X/Y.../Z/" If script finds no such remote path on server B it will continue copying second file which directory exists. File should be copied with permissions, group, owner and creation time. X/Y... are various directories path. I want setup a cron job to execute this script every 10 minutes. So the performance is very important in this case. Thank you.

• Problem running application on windows server 2008 instance using amazon ec2 service and WAMP

  - by Siddharth

  I have a basic (small type) windows server 2008 instance running on amazon ec2. I've installed WAMP server on to it, and have also loaded my application. I did this using Remote desktop Connection from my windows machine. I'm able to run my application locally on the instance, however when I try to access it using the public DNS given to it by amazon, from my browser, I'm unable to do so. My instance has a security group that is configured to allow HTTP, HTTPS, RDP, SSH and SMTP requests on different ports. In fact I have the exact same security group as the one used in this blog, http://howto.opml.org/dave/ec2/ I did almost everything same as the blog, except for using a different Amazon Machine Image. This is my first time using amazon ec2, and i can't figure out what I'm doing wrong here

• Are there any Powershell modules specifically for IIS6 administration?

  - by program247365

  I'm looking to manage/administer many IIS6 servers remotely via Powershell (query sites, iis settings, etc). Is this possible? Is there a Microsoft-supported module out there? Or do I have to use WMI-Object/WebAdministration? If so, could some one give me some quick instructions on doing some simple "get info" commands in Powershell to a remote IIS6 machine? (It's frustrating that there is a nice IIS7/Microsoft-supported module out there: http://learn.iis.net/page.aspx/428/getting-started-with-the-iis-70-powershell-snap-in/ But not an IIS6 one easily found.)

• Windows Server 2003: Nat Port Forwarding Not Working

  - by jM2.me

  The setup is following: Internet (108.99.XXX.XX) <- Windows Server 2003 (10.0.0.1) <- Switch <- Office Computers (10.0.0.100-200 some static routes some manual some automatic) Windows Server has NAT installed on it and two network interfaces are configured properly. The problem is, whenever I try to forward port 80 (or any other) from office computer (lets say 10.0.0.100), it fails. Nic #1 Settings: All settings are obtained from ISP Nic #2 Settings: Set manually IP: 10.0.0.1 Mask: 255.255.255.0 Nat Server is configured to automatically assign IP addresses to private network. Settings are: IP: 10.0.0.0 Mask: 255.255.255.0 Forwarding was done in Routing and Remote Access (local) - IP Routing - NAT/Basic Firewall - Local Area Connection (right click_properties) - services and ports - Web Server HTTP - Private Address: 10.0.0.100 SO what is causing the problem of failure to forward any port from other computer inside private network?

• Using socat to exec php cli

  - by RoyHB

  There are multiple client programs that periodically connect to a port on my server and send a single line of text. When a connection to the port is made I need to start a PHP CLI script that processes the data. There may be many of the remote scripts running/connecting at more or less the same time so I think it would be best if socat forked a process for each connection to run the script. I've gotten socat to do most of what I need, using the command socat tcp-l:myport,fork exec:mypath/socatTest.php I can read the input on php://stdIn. All is good. The problem is that the process doesn't seem to fork, so if a second external program sends data while another is doing the same it gets a connection refused error. Where have I gone wrong?

• Request Multiple Maya Floating Server Licenses for extra Satellite clients

  - by Rob

  Hello all: I am currently setting up a 'render farm' for Maya 2008 Unlimited. One Maya workstation license comes with the ability to render on eight satellite nodes. It works perfect, the remote rendering works like a charm. However, we have additional boxes to set up as satellite rendering nodes, and we have extra Maya workstation licenses. Ideally, the workstation can take two licenses and thus render on 16 nodes, but I haven't been able to figure it out, or determine if it is actually possible. It's a big project, where rendering the entire thing is in the scope of weeks, so the speed up would be worth it. Any thoughts?

• Login-time quota for VPN users

  - by Isaac

  I have configured Routing and Remote Access Service in Windows Server 2003 as the VPN server. VPN users are defined in Active Directory which is running on this server too. How i can configure the server to give each user a limited download size (for example 1GB) and does not authenticate them when they exceeds their download quota. The VPN server should also disconnect the users that reach their quota. Update: Apparently a third-party RADIUS server could provide this feature. One solution I have found is TekRADIUS but it is commercial. FreeRADIUS is a open-source free RADIUS server but I am not sure if it could these kind of features.

• Backup solution

  - by user66115

  We are currently looking for a new backup solution. Our current network is 5 remote location with a tape backup in each plant. Right now we are looking at a MPLS VPN and running backups out of our main plant. The main thing that we backup are user private folders and department files. And each plant has it's own file server that houses CAD drawings. My main plan is to have every thing but that CAD drawing at the main faculty. We would start with a main backup of the drawing files and then do change backups back to the main plant. Besides tapes what would be the best way to backup. Our contact at Pc Connection is point us toward a Tandberg Data device.

• SSH and Latent Connections (e.g., satellite connections)

  - by user71494

  Most of the week I live in the city where I have a typical broadband connection, but most weekends I'm out of town and only have access to a satellite connection. Trying to work over SSH on a satellite connection, while possible, is hardly desirable due to the high latency ( 1 second). My question is this: Is there any software that will do something like buffering keystrokes on my local machine before they're sent over SSH to help make the lag on individual keystrokes a little bit more transparent? Essentially I'm looking for something that would reduce the effects of the high latency for everything except for commands (e.g., opening files, changing to a new directory, etc.). I've already discovered that vim can open remote files locally and rewrite them remotely, but, while this is a huge help, it is not quite what I'm looking for since it only works when editing files, and requires opening a connection every time a read/write occurs. (For anyone who may not know how to do this and is curious, just use this command: 'vim scp://host/file/path/here)

• IPP Printing from Windows 7 Ultimate

  - by Casey

  I have network IPP working on Ubuntu and Windows XP. On my Windows 7 instance, it refuses to acknowledge the remote server connection. Can anyone suggest how to configure this correctly? My install steps are: Add Printer Add a Local Printer Create a New Port and "Standard TCP/IP Port" Enter hostname http://host:631/printers/Printer_Name After that it says the printer is not detected, asks me to pick a driver, and finish up. Trying to use the device does not produce any output? If anyone has got this work, I would really appreciate a fix.

• search nfs network volume from mac client

  - by user1440190

  Asked: how does a Mac OSX SL or Lion user search the cluster for a particular file (foo.txt) "From the cluster, you would need to run some form of recursive lookup for the file desired. As an example, using 'find'. RAM-1# find /ifs |grep test.txt /ifs/Elements/avid2test.txt /ifs/Elements/test.txt I would suggest contacting Apple support regarding their recommendation for searching for files on remote file systems from the Mac client itself" OK that's great, but I don't want users using CLI !!! Anyone know a good method (non-CLI)? Spotlight is not an option. BTW cluster is roughly 80TB

• Mailer Daemon greeting failed

  I wrote a tool that sends automated mails to a couple of addresses. This worked for a couple of weeks. Now since yesterday I get Mailer-Daemon responses like this Hi. This is the qmail-send program at test.test2.net. I'm afraid I wasn't able to deliver your message to the following addresses. This is a permanent error; I've given up. Sorry it didn't work out. testuser@domain.com: Connected to 123.456.789.10 but greeting failed. Remote host said: 554 foo.bar.com I'm not going to try again; this message has been in the queue too long. Does someone have an idea what I can do now?

• Disable Network settings (TCP/IP & DNS) on Windows 7 Ultimate

  - by TiD91

  i also read this discussion here How to disable Tcp/Ip settings in windows 7 via GPO? about what i want to do but i still have problems. So here i am: i have a desktop pc with two accounts, both with Administrative rights. One is used by the entire my family, in particular by my brother. The problem is that i set some DNS and IP configurations to let be possible the VNC connection from remote. Now i would like to disable the network settings (TCP/IP and DNS) to prohibit my brother to change it preventing me to connect to it. So how can i do this? I set the policies from GPO but i still can change these settings from his account. Here's a pic of Registry Keys: http://imageshack.us/a/img339/3310/famigliapc2012092017274.png what didn't i do?

• DD-WRT with both https and sshd running in port 443

  - by Bruno

  I have a buffalo router with dd-wrt v24 SP2. After setting up the basic stuff, I enabled the https access to the admin page. Several days later, while setting up remote ssh, I changed the default port from 22 to 443. And now..well :) You got the picture :) I can ssh the router but I have no web access to it's admin page. Before rushing to a cold-hearted configuration reset, is there any way to change the ssh port from a shell? Or make dd-wrt accessible thru basic http?
