• Setup a new domain controller over a temporary VPN, but now Windows delays startup?

  - by Kris Anderson

  I'm migrating servers from colo locations to Amazon's VPC EC2 instances. If anyone hasn't worked with Amazon VPC before, VPN is a pain in the arse! Anyways, I setup a new server that acts as the domain controller for our Amazon VPC. In order to migrate all the user accounts from our existing domain controllers I manually connected to our colo VPN using my user account on the new Amazon EC2 machine. I was able to join the domain and the new Amazon server became another domain controller on our network. So far so good. The problem I'm having is that when booting the EC2 domain controller (which is no longer connected to the VPN so it can't communicate with the existing controllers), it takes a good 6-8 minuted before I can remote into the server (instead of the 1-2 minutes it should take). Also, during this time most of the services we also run (like IIS) also give 404 errors until the 6-8 minutes have passed. It's almost like the domain controller is attempting to reach the other domain controllers first and after 6-8 minutes it falls back to the one located on the local machine? I don't think that's what's happening though, because Server 2008 R2 doesn't have primary and backup domain controllers. They're all equal as far as Windows is concerned. For my network adapter I have only one DNS listed, 127.0.0.1, so it should be looking up the local domain controller and not the other domain controllers it connected to over VPN when VPN was enabled. In the server logs I'm seeing these warnings pop up during a reboot: The winlogon notification subscriber is taking long time to handle the notification event (CreateSession). The winlogon notification subscriber took 409 second(s) to handle the notification event (CreateSession). Any ideas on what's happening here? I would try removing the existing domain controllers from the new Amazon EC2 machine, but I still need to connect over VPN a few times to migrate some data between the servers, and I don't want that change being reflected back to the other domain controllers in our colo locations.

• nconf deployment.ini configuration for a basic Nagios server on CentOS 6.2

  - by jshin47

  I have set up nconf and Nagios but I cannot figure out how to configure deployment.ini to properly deploy the generated configuration to /usr/local/nagios/etc. Here are the directory listings of interest: [jshin@nag0 tmp]$ ls Default_collector global [jshin@nag0 tmp]$ cd Default_collector/ [jshin@nag0 Default_collector]$ ls advanced_services.cfg hostgroups.cfg service_dependencies.cfg services.cfg host_dependencies.cfg hosts.cfg servicegroups.cfg [jshin@nag0 Default_collector]$ cd .. [jshin@nag0 tmp]$ cd global/ [jshin@nag0 global]$ ls checkcommands.cfg contacts.cfg misccommands.cfg timeperiods.cfg contactgroups.cfg host_templates.cfg service_templates.cfg [jshin@nag0 global]$ cd .. [jshin@nag0 tmp]$ cd /usr/local/nagios/etc/ [jshin@nag0 etc]$ ls cgi.cfg htpasswd.users nagios.cfg objects resource.cfg [jshin@nag0 etc]$ cd objects/ [jshin@nag0 objects]$ ls commands.cfg localhost.cfg switch.cfg timeperiods.cfg contacts.cfg printer.cfg templates.cfg windows.cfg Here is my deployment.ini (pretty much the default setting) ;; LOCAL deployment ;; [extract config] type = local source_file = "/var/www/html/nconf/output/NagiosConfig.tgz" target_file = "/tmp/" action = extract [copy collector config] type = local source_file = "/tmp/Default_collector/" target_file = "/usr/local/nagios/etc/Default_collector/" action = copy [copy global config] type = local source_file = "/tmp/global/" target_file = "/usr/local/nagios/etc/global" action = copy reload_command = "service nagios restart" What I am wondering is why the directory structure that the default deployment.ini seems to suggest, with Default_collector and global, is different from the one that Nagios has by default, with only a folder called objects. What am I missing? Or more importantly, how does your deployment.ini look?

• Physical-to-virtual for personal use

  - by Journeyman Geek

  One of my current projects involves reducing the number of old computers lying around. So far, the office systems have been downsized from 5 to 2. One system which had no data on it was dumped entirely, while three other identical boxes were consolidated into to one (I swap hard drives as needed and they just work(tm)). I want to make further cuts. The physical systems in question all run windows xp sp3, and were old Pentium 4s with 256 MB of RAM. Currently, I have got a VirtualBox running on another system. My intention is to migrate all services to that. We can assume that disk space and RAM on the host is not an issue. I'd rather not go with a client-server physical-to-virtual (P2V) method like what VirtualBox uses now. I have a few specific concerns as well - specifically whether I'd need to reactivate or sysprep for dissimilar hardware first. An offline tool for imaging (Windows or Linux) would not be an issue since the drives could be mounted onto another system I have anyway or I could use a LiveCD. What would be my options for P2V conversion, and what would I need to keep in mind when doing this?

• Windows Server 2003 DC hangs after network drivers update

  - by tcv

  Earlier today, we attempted to update the Broadcom BCM5716C network drivers on a Windows Server 2003. (Dell PowerEdge T310, FWIW). Since then we have not been able to boot the server in any normal mode. Safe Mode works. Safe Mode with Networking and regular bootups hang at "Applying Network Settings." I haven't tried Last Known Good Configuration nor have I tried Directory Services Restore Mode. I should also mention that the longest I've allowed "Applying Network Settings" was perhaps 30 minutes. I spoke to Dell since the server is under a basic warranty. They sent me the original Broadcom drivers. The trouble seems to be, however, that since I can only boot in Safe Mode, I can't install the application package as given. In safe mode, I receive the error: "The system administrator has set policies to prohibit this installation." I can install the drivers independently, but that doesn't allow the NICs to work. The most I've been able to get are Code 10 errors on each NIC. I plan to get back to the site tomorrow to attempt installation of a different NIC. I'm wondering what else I can try.

• User cannot access a system DSN on Windows Server 2008

  - by Ra Osolage

  We run our SQL Server services using a low privileged domain account. That account is NOT a local admin on the OS. Only access I give the user account is assigned during install of SQL: full control over its mount points and then everything else is granted by the SQL Server 2005/2008 installer. I need to create a linked server in SQL Server 2008 to an ODBC data source. So I remoted into the computer using my domain account, which is part of a group that DOES have local admin privs to the OS. I created a system DSN and configured it to connect to another SQL Server. The DSN works perfectly when I test it. However, when I try to create the linked server, I get an error. It appears to me that the DSN is invisible to the domain account that SQL Server is running as. It seems that this problem is only happening to me on Windows 2008 servers. Does anybody know whether there's anything that you need to do after creating a DSN to make it visible for other users to access?

• Backup and Archive Strategy Question

  - by OneNerd

  I am having trouble finding a backup strategy for our code assets that 'just works' without any manual intervention. Goal is to have an off-site backup (a synchronized one) so that when we check-in files, create builds, etc. to the network drive, the entire folder structure is automatically synchronized and backed-up (in real time, or 1x per day) at some off-site location so if our office blows up, we don't lose all of our data. I have looked into some online backup services, but have not yet had any success. Some are quirky/buggy, others limit file size and/or kinds of files (which doesn't work well for developer files). Everything gets checked in and saved to a single server (on a Raid Mirror), so we just need to have a folder on that server backed up/synchronized to some off-site location. So my question is this. What are you using for your off-site backup strategy. What software, system, or service? Is there a be-all/end-all system of backing up your code assets that I just haven't found yet? Thanks

• Cannot start MySQL

  - by Mohamed Nour El-Din

  I used this command from shell to repair all Databases mysqlcheck -u root -p --auto-repair --check --optimize --all-databases and after that I restarted the server when it came back alive again I tried to open my vBulletin forum but I recived Database error message. and also tried to open phpMyAdmin but I received this error : #2002 - The server is not responding (or the local MySQL server's socket is not correctly configured). I checked the services list and found that the MySQL Service is not listed, so I tried to start it from shell I receive this error : Starting MySQL.Manager of pid-file quit without updating fi[FAILED] could anyone help me in that ? thanks in advance. update I found these lines in the log file 101101 01:36:01 mysqld started 101101 1:36:01 [Warning] Asked for 196608 thread stack, but got 126976 101101 1:36:01 [ERROR] /usr/sbin/mysqld: Table './mysql/user' is marked as crashed and last (automatic?) repair failed 101101 1:36:01 [ERROR] /usr/sbin/mysqld: Table './mysql/user' is marked as crashed and last (automatic?) repair failed 101101 1:36:01 [ERROR] Fatal error: Can't open and lock privilege tables: Table './mysql/user' is marked as crashed and last (automatic?) repair failed 101101 01:36:01 mysqld ended What should I do then ?

• Use Alladin eToken with ThunderBird and other tool

  - by Yurij73

  I'm looking for an example on how to setup the eToken PRO Java device to work with Mozilla Thunderbird and with other Linux tool such as PAM logon. I installed distributed pkiclient-5.00.28-0.i386.RPM from the official product page eToken Pro but that tool only handles importing/exporting certificates on the device. I read a glance an old HOWTO from eToken on Linux, but I couldn't install pkcs11-lib for this device as recommended for Thunderbird use this crypto device. It seems my usb token isn't listed in system, unless lsusb show it, so that is the matter modutil -list -dbdir /etc/pki/nssdb Listing of PKCS #11 Modules NSS Internal PKCS #11 Module Blockquote slots: 2 slots attached Blockquote status: loaded Blockquote slot: NSS User Private Key and Certificate Services Blockquote token: NSS Certificate DB Blockquote CoolKey PKCS #11 Module Blockquote library name: libcoolkeypk11.so Blockquote slots: 1 slot attached Blockquote status: loaded Blockquote slot: AKS ifdh [Main Interface] 00 00 token: is my token absent? on other hand i don't know which module is convenient to Java Pro, does CoolKey does all the job well?

• How do I get "Back to My Mac" (using MobileMe) from Windows?

  - by benzado

  I have a MobileMe subscription and a Mac at home with "Back to My Mac" enabled. When I'm away from home, this service lets me use another Mac to connect to my Mac back home and access file sharing, screen sharing, etc. As far as I know, the service doesn't use any proprietary protocols, so in theory I should also be able to get "Back to My Mac" from a Windows PC. This MacWorld article explains how it works. Basically, it uses Wide-Area Bonjour to give your Mac a domain name like hostname.username.members.mac.com. Remote computers can find your Mac using that address, then connect to it using a private VPN. The "Wide Area Bonjour" part seems to make it a little more complicated than simply a regular domain name, though. Note that I'm not interested in using the methods described by LifeHacker, which doesn't use the MobileMe service at all. I don't want to use a totally different dynamic DNS service. I'd like to use the one I'm already paying for, or at least find out why that's not possible from Windows. Also, my primary problem is finding a network route back to my mac... once I've got that I know how to enable services so that Windows can talk to it. UPDATE: Based on some additional research, it appears that Apple is only assigning IPv6 addresses to the hostname.username.members.mac.com names. So any solution will require enabling IPv6 support on Windows, if possible.

• Migrating 10-15 Websites Running Linux, LAMP, RoR, WordPress

  - by Michael

  Task is to move 10-15 websites running Linux to new servers hosted by Amazon. These boxes are currently on dedicated servers. Some sites are running WordPress, some have custom CMS, and others might have RoR applications. Unfortunately, there is sparse documentation regarding each site and how services/files are dependent on each other which means there is a lot of detective work that needs to take place. My goal is to properly document each site, what makes them work, etc., so future admins have at least something to work with. Currently my strategy is to download each site so I have a backup of the files then scan through them looking for configuration files -- db connections, apache configs, etc. Then, create a nice spreadsheet with these findings and migrate these out to the new server. My question to ServerFault is this, are there things you would look out for? Easier ways to handle this task that I'm missing? Points will be awarded to answers that help with efficiency. Thanks in advance.

• Proper Network Infastructure Setup DMZ, VPN, Routing Hardware Question

  - by NickToyota

  Greetings Server Fault Universe, So here's a quick background. Two weeks ago I started a new position as the systems administrator for an expanding health services company of just over 100 persons. The individual I was replacing left the company with little to no notice. Basically, I have inherited a network of one main HQ (where I am situated) which has existed for over 10 years, with five smaller offices (less than 20 persons). I am trying to make sense of the current setup. The network at the HQ includes: Linksys RV082 Router providing internet access for employees and site to site VPN connecting the smaller offices (using an RV042 each). We have both cable and dsl lines connected to balance traffic (however this does not work at all and is not my main concern right now). Cisco Ironport appliance. This is the main gateway for our incoming and outgoing emails. This also has an external IP and internal IP. Lotus domino in and out email servers connected to the mentioned Cisco gateway. These also have an external IP and internal IP. Two windows 2003 and 2008 boxes running as domain controllers with DNS of course. These also have both an external IP and internal IP. Website and web mail servers also on both external and internal IPs. I am still confused as why there are so many servers connected directly to the internet. I am seriously looking to redesign this setup with proper security practices in mind (my highest concern) and am in need of a proper firewall setup for the external/internal servers along with a VPN solution about 50 employees. Budget is not a concern as I have been given some flexibility to purchase necessary solutions. I have been told Cisco ASA appliance may help. Does anyone out in the Server Fault Universe have some recommendations? Thank you all in advance.

• MySQL Master-Master w/ multiple read slave cost effective setup in AWS

  - by Ross

  I've been evaluating Amazon Web Services RDS for MySQL and costing out potential scenarios involving a simple multi-AZ deployment read/write setup vs. a multi-AZ deployment mysql master (hot-standby) with additional read-only slaves. the issue I'm trying to cost-optimize includes their reserved instance vs on-demand instances. Situation 1: purchase reserved multi-az setup for Extra-large-hi-mem(17GB RAM) instance for $5200/yr and have my application query the master all the time. the problem is, if I don't need all the resources of the (17GB RAM) all the time and therefore, especially not a hot-standby, what alternatives for savings can a better topology create, like potentially situation 2 below: Situation 2: purchase reserved multi-az setup using smaller master instances than above for the master-master hot-standby to receive the writes only. Then create and load balance several read-only slaves off the master and add/remove and/or scale up/down the read slaves based on demand. This might only cost $1000 + the on-demand usage of the read slaves. My thinking is, if I have a variable read-intensive application load, with low write load, the single level topology in situation 1 means I'm paying for a lot of resources at the write level of topology when I don't need them there. My hope is that situation 2 can yield cost savings from smaller reserved instances on the master-master resource level allowing me to scale up and down and/or out on the read-level according to demand as needed. Does anyone see a downside to doing this or know of some reason this isn't possible with RDS? Any other thoughts or advice always welcome of course. Thanks in advance, R

• Android failure to boot on LG [migrated]

  - by Ukavi

  I need to recover data from my AT&T LG Thrill Android Phone Background: My AT&T LG Thrill phone's battery died a couple of days ago because I forgot to charge it. When I charged the phone and tried to turn it on, it showed the LG logo followed by the dropping balls and the AT&T "Rethink Possible" screen. I then get a mesage that the Application Google Services Framework has crashed and the phone goes into a loop with the dropping balls showing again followed by "Rethink Possible" screen. This sequence repeats itself over and over and the phone does not get out of this loop. I have been able to go into the recovery screen (both Safe Mode and the Android Recovery Service) and have cleared cache, etc. However, I DO NOT want to wipe user data and restore to factory settings as this will wipe all of my data (pictures, application data, etc). Solution Needed: I need a suggestion to a way of accessing my data so that I can back it up onto an SD card/computer. I DO NOT want to root the phone as this may void the warranty. What I'm looking for is a way of perhaps putting the original flash image on the micro SD card and then have the phone read that image. Or some other similar solution that will get the phone out of this loop and allow me to get to the data.

• Menu command stuck on screen

  - by 280Z28

  For some reason, periodically when I select a menu command, the command label gets "stuck" on the screen and won't go away. I can close all open applications, including whichever one I was using when it got stuck, but it still won't go away. In the screenshot below, I opened an new instance of IE just to show how the label stays on top. The label was not created by this instance of IE. Edit with the source: The label that gets stuck is the first menu command I select in IE. If a label is already stuck, a new one does not get stuck (regardless of which instance(s) of IE are involved). Based on this knowledge, I now just open IE on my secondary monitor, carefully open the context menu so the Properties command is in the bottom corner, and click it. This is not a solution... The label never moves and is transparent to mouse input (if I click it, it's as if I clicked the item behind it). The label does not go away if I close all running applications. I haven't tried stopping services or closing system tray items like Live Mesh. The label does go away if I change the screen resolution and then change it back. Any ideas how I can stop this from happening? It's happened a half dozen times since yesterday and it's becoming quite disrupting to my work. Obviously I added the circle in MS Paint. That part isn't stuck. ;)

• Deploying workstations - best practices?

  - by V. Romanov

  Hi guys I've been researching on the subject of workstation deployment for a while, and found a ton of info and dozens different methods and tools, but no "best practice" method that doesn't lack at least one feature that i consider required for the solution to be perfect. I'm currently interested in windows workstation deployment, but if the tools can be extended to Linux, then it's an added value. I want the deployment tools I use to be able to do the following: hardware independent - I want my image or installation to have a minimum of hardware and driver dependency, so that i can use a single image/package for all workstations easily updatable - I want to be able to update my image as easily as possible without redeploying/rebuilding/reimaging all configurations PXE bootable deployment - I want the tools to be bootable off the network so that I don't need a boot cd/DOK. scriptable for minimum human input - Ideally, the tool should run automatically after being booted and perform a "default" deployment (including partitioning) unless prompted otherwise. i.e - take a pc, hook it up, power on, PXE boot and forget about it until the OS is deployed. I found no single product or environment that does all this. Closest i came to is the windows deployment services/WIM image format. I also checked out numerous imaging and deployment tools including clonezilla, ghost, g4u, wpkg and others, but most of them lack the hardware Independence and updatability features. We currently have a Symantec Ghost server setup that does imaging over the network, but I'm not satisfied with it as it has all the drawbacks i listed above. Do you have suggestions how to optimize the process of workstation deployment? How do you deploy them in your organization? Thanks! Vadim.

• Dynamic ARP Entries turning into Static ARP entries

  - by Zach

  I recently acquired a client that has a strange ARP caching issue on one of thier servers. I have a server that will eventually start turning it's dynamic ARP entries into static ARP entries. This causes problems because when the machine that has a static ARP entries on this server receives a new IP via DHCP, then the server is not able to communicate with the clients. Clearing the ARP cache resolves the issue and the server is fine for about a week and then it starts slowly turning ARP entries into static ARP entries. I haven't narrowed it down to when or how many it starts to do, but slowly you start seeing 1 static ARP and then 5 and then 10. The server in question is a Windows Server 2003 SP2. It is a DC, DHCP, and DNS server. I've checked the DHCP scope options and there's nothing in there that would indicate anything to do with static ARP entries. The only thing different between this DNS server and our other DNS server is that the 'Dynamically Update DNA A and PTR records for DHCP clients that do not request updates' is checked on the problematic server. I've done a bit of research about this and it seems that this may happen if any PXE type services are running, from what I can tell, there is nothing running a PXE server. I'm a bit lost as I have never seen dynamic ARP entries start to turn into static ARP entries. Right now my solution is a schedule task that runs every 24 hours to clear the ARP cache (arp -d *). I would like to not rely on this schedule task. Has anybody seen this before or have any suggestions on how to troubleshoot this?

• How do I find funny pictures?

  - by Hanno Fietz

  No, not lolcats. And I'm not really looking for a specific site, either. I have often wished that I had some funny picture to illustrate a presentation, a website, a post, an email, or something else. Google image search and stock photo services have hardly ever helped me, although that may be because I'm doing something wrong. Jeff Atwood seems to have no problem to find funny pictures for his codinghorror and stackoverflow blogs, as well as for the error messages on the trilogy sites. One of my favourites was this elephant. Other bloggers also seem to be quite good at it. I'm wondering if I simply lack the creativity or if there's sources or methods I don't know about. I could think of the following ways to get pictures, but I'm not sure whether this is really "how they do it". keep a collection of pictures that you stumbled upon and liked (takes quite some time to build up to a proper library), when you need a picture, there's one in there maybe have pictures on paper, too, like from magazines or ads. when you are looking for a picture, search online (Flickr, Google, stock photos). This has never really worked for me, I don't know why. produce the pictures yourself, i. e. have a good library of source material or find some online and apply some creativity and suitable software. I could imagine that this could work well once you have the practice.

• Cannot resolve Hostname to IP, but IP to hostname works

  - by dotnetdev

  I have deployed a bunch of windows server VMs on a cloud hosting service. These machines are all joined to a domain controller on the same service, which also hosts DNS. All of the domain-joined machines have dynamic IP (along with the DC). If I try to resolve any of the hostnames remotely, it fails. For example, I am in SQL Server Reporting Services and I need to connect to a remote server. I provide the hostname of the desired target server and this fails, but then if I provide the IP, this works. How can I pass the hostname and have this resolve to IP? Is there anything I need to look for in the DNS server? It has records of the hostnames (in forward lookup I think), but reverse is empty. Isn't it the case that forward lookup resolves ip to hostname and reverse resolves hostname to ip? Also, I don't know what he subnet mask because this is not in my control, so the machines may not be in the same subnet - can this be a cause of the problem? Where is the problem? Thanks

• MySQL Workbench is not finding MySQL service? [closed]

  - by PhADDinTraining

  I set up a local MySQL server, currently with no databases. I'm trying to create a new server instance profile in MySQL Workbench to manage the server, and during the Create New Server Instance Profile wizard, it gets to the Windows Management section and tells me that No MySQL service found. I went into Task Manager and found the process mysqld.exe to be running, under the user name of NETWORK SERVICE. Then I went into the Services tab and found that MySQLServerName (I custom named the Windows service) is also there, and status is running. I ran cports and looked at what ports mysqld.exe is using, and ran a telnet command on that port. It's reporting that the port is being listened in on. I then ran the MySQL Command Line Client to be sure, and after \r it gives me a proper connection ID and a list of databases (NONE at this point). But with all this, I can't make the wizard find a running service. I've Googled this and found no answers, so please, if someone would help shed some light on this issue that'd be great!

• How to set up a serial connection to a Windows 7 computer

  - by oli_arborum

  I need to set up a "dial in" connection to a Windows 7 (Ultimate) computer via a serial null-modem cable to be able to connect from a Windows XP client to that computer and exchange data over IP. Question 1: How do I do that? I did neither find the information via Google nor in the MSDN. Seems like no one tried ever before... ;-) I already managed to install a legacy modem device called "Communications cable between two computers" and found the menu entry "New Incoming Connection..." in Network and Internet Network Connections. When I finish this wizard I get the message that the "Routing and Remote Access service" cannot be started. In the event viewer I see the following error messages: "The currently configured authentication provider failed to load and initialize successfully. The requested name is valid, but no data of the requested type was found." (Source: RemoteAccess, EventID: 20152) "The Routing and Remote Access service terminated with service-specific error The requested name is valid, but no data of the requested type was found." (Source: Service Control Manager, EventID: 7024) The Windows 7 installation is "naked", i.e. no additional software or services are installed. Question 2: Am I on the right path to set up the connection? Question 3: How can I get the Routing and Remote Access service running?

• Postfix Whitelist before recipient restrictions

  - by GruffTech

  Alright. Some background. We have an anti-spam cluster trucking about 2-3 million emails per day, blocking somewhere in the range of 99% of spam email from our end users. The underlying SMTP server is Postfix 2.2.10. The "Frontline defense" before mail gets carted off to SpamAssassin/ClamAV/ ect ect, is attached below. ...basic config.... smtpd_recipient_restrictions = reject_unauth_destination, reject_rbl_client b.barracudacentral.org, reject_rbl_client cbl.abuseat.org, reject_rbl_client bl.mailspike.net, check_policy_service unix:postgrey/socket ...more basic config.... As you can see, standard RBL services from various companies, as well as a Postgrey service. The problem is, I have one client (out of thousands) who is very upset that we blocked an important email of theirs. It was sent through a russian freemailer who was currently blocked in two of our three RBL servers. I explained the situation to them, however they are insisting we do not block any of their emails. So i need a method of whitelisting ANY email that comes to domain.com, however i need it to take place before any of the recipient restrictions, they want no RBL or postgrey blocking at all. I've done a bit of research myself, http://www.howtoforge.com/how-to-whitelist-hosts-ip-addresses-in-postfix seemed to be a good guide at first, almost fixing my problem, But i want it to accept based on TO address, not originating server.

• Virtual Wifi Issue Windows 7

  - by Matt

  Lately I've been trying to use my laptop as a wireless router in my room. I have it connected to my school's network through ethernet, and I want to set up wireless so that I can use Wifi on my Android phone and iPod Touch. In the past, I used Connectify, but I started having an issue where my phone would find the network, connect, attempt to get the IP, and then suddenly the network would disappear. Then it'd pop up again, and the same process would happen over and over. I decided that I'd totally uninstall Connectify, but after that, neither Virtual Router Manager nor the command prompt could create a viable network either. My phone and even my iPod now encounter the same problem. Neither can successfully connect. So evidently there is something wrong with the laptop's virtual wifi feature, and I have no idea what that could be. I've tried enabling certain services that virtual wifi supposedly relies on, but some of them don't start, namely Remote Access Connection Manager. But I also have read that these enable on their own and that if they are normally not enabled it's fine. Furthermore, I even uninstalled and reinstalled the drivers for my wireless card. Any ideas as to why my virtual wifi won't function? Anything? I really would love to get this working...

• Xvnc4 started from xinetd only displays empty gray X screen

  - by scott8035

  I'm attempting to setup an Ubuntu 10.10 box so that anyone can connect to port 5900 and be greeted by the gdm login manager. To do so, I added a vnc entry in /etc/services and I am starting Xvnc4 using this xinetd config file: service vnc { protocol = tcp socket_type = stream wait = no user = nobody server = /usr/bin/Xvnc server_args = -geometry 1000x700 -depth 24 -broadcast -inetd -once -securitytypes None } This kind of works...I can start multiple sessions all to port 5900, and I get an X screen. The problem is that I only get an empty, gray X screen with no applications started. I know when you run vncserver from the command line it will look to your ~/.vnc/ directory for your passwd and xstartup files, and I think what I want to do is put "gnome-session" into the xstart file. However, which xstartup file? The running user is "nobody" who obviously doesn't have a ~/.vnc/ directory. I tried a /root/.vnc/xstartup file and a ~scott/.vnc/xstartup file and it doesn't look like they were even read. I changed the xinetd vnc service so that it would "strace" Xvnc4. I looked thru all the "open" lines and didn't get a clue as to what file it was trying to read for xstart. Can anyone help? I just want a terminal server where the user is presented with a gdm login screen.

• debian VM refusing all traffic apart from http

  - by james lewis

  I've got a VM with a fresh install of Debian (wheezy) and I've installed node and mongo on it. The VM is using a bridged network connection so I was expecting to be able to point my host machines browser at the ip address of the Debian VM (port 1337 for my node example or port 28017 for my mongo status page) and see one of the two services (node or mongo). My requests are refused though. As far as I can tell Debian allows all traffic by default and you have to manually configure iptables to drop traffic. I've checked iptables and it says it's setup to allow anything through. It looks like this: root@devbox:/home/jlewis# iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination As a test I setup nginx and I was able to get to the nginx landing page from my host no problems so obviously http traffic is allowed. I then set nginx up to forward all traffic upstream to mongo - no problems there, I was able to see the status page. I then did the same for my example node server and again, no problems. So http traffic is fine, but all other traffic is blocked. Anyone know why debian might be refusing all other traffic other than iptables being setup to drop it?
