• VMWare web UI intermittent access on CentOS

  - by PeteWilliams

  Hiya, I've got a CentOS 5.2 server that I'm trying to get set up as a development environment. As part of this, I planned to install VMWare Server 2 and set up several virtual development servers. I've got as far as installing VMWare Server 2 but access to the remote control panel is only working intermittently. If I access it through Firefox at https://127.0.0.1:8333/ui/# it usually says either: "Connection intterupted: connection was reset before the page loaded" Or "Firefox can't establish a connection to the server at 127.0.0.1" But every now and then it lets me in and I'll manage a few clicks in the web UI before it kicks me out with the following error: "The server could not complete a request (HTTP 0 ). The server encountered an unexpected condition that prevented it from fulfilling the request. If this problem persists, please contact your system administrator." I've done all the updates available in CentOS except one OpenOffice one that is causing a conflict, and I re-ran wmware-config.pl after updating the kernel. Though I went with all the defaults as I don't really know what I'm doing! I've since rebooted and nothing changed. I've also tried accessing the control panel remotely from another machine in the network and the results are the same. Does anyone have any ideas what might be causing this and how I can resolve it? I'm afraid I'm a developer playing at sys-admin, so I may be missing something obvious! Many thanks Pete Update I have now reinstalled both the operating system and VMWare and I'm still getting the same issue. I wonder if it's a result of the settings I'm putting in on the config.pl script..?

• Shortcut to "printer and faxes" on another computer

  - by Doltknuckle

  I have a print server running windows server 2008 that has about 50 printers on it. In windows XP, I was able to connect to the server using the UNC name and make a shortcut to the "printers and faxes" folder. (For the record, I know that it really isn't a folder, but that's outside the scope of this question.) I have recently switched to windows 7 and I find that the jump lists are really useful. One of the things I want to do is make it easy to connect to that server's "printers and faxes" folder. I would like to use something like a shortcut that I can open and go immediately to that location. The problem is that windows 7 doesn't have a way to create a shortcut like you could in WinXP. They have a button on the toolbar that says "view remote printers" which sends you to the correct folder. I'd like to avoid having to type out the server name. I also can't use the "view network" link in windows explorer. Our organization has over 6,000 machines and viewing the network lists all of them. This is all about saving time by using the minimum number of mouse clicks and key presses in normal operation. Does anyone have any suggestions?

• then an error occurred during the login process - Connection Error 233

  - by scott brunner

  We have SQL Server 2008 installed on 64Bit Windows Server 2003. When we try connect to the local SQL Server using SQL Server Management Studio at the console, we get the error: A connection was successfully established with the server, but then an error occurred during the login process. provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe. When we try TCP from same local SSMS to local server, we get the same error but intead of the pipe message its something like "connection forcibly closed". Now, here is the strange part - we CAN connect to this SQL Server from any other machine on the network using SSMS. - AND - WE CAN'T connect to ANY SQL Server from the problem server. So it seems the SQL Server instance is fine and accepting remote connections. However, the SSMS on that machine will not connect to any SQL Server even remotely. When we try an ADO.NET connection from C# remotely we can connect, run that same code on the console of the trouble server and we get the same errors. How can this be solved?

• OS X (10.6) Apache Sudden Death, Nginx not working either...

  - by Jesse Stuart

  Hi, I turned on my computer today and apache wasn't working. This is weird as its been working for the last 6 months without issue. The only thing I did which may of caused a problem, is I uninstalled a bunch of gems. This shouldn't be the issue though as apache doesn't rely on gems. I decided to give nginx a try to see if it would work and have the exact same issue. The symtoms are: I go to http://localhost and get the browsers default 404 page (not rendered by apache/nginx) No error is found anywhere (I checked all logs) Apache is rinning (also tried with Nginx) How can I debug this to find the root of the problem? I can't think of why this would be happening. I've tried repairing permissions in case this was the issue, apparently it wasn't. Everything was working the other day, and nothing changed in the apache config. Update: Here is the output of telnet localhost 80 $ telnet localhost 80 Trying ::1... telnet: connect to address ::1: Connection refused Trying fe80::1... telnet: connect to address fe80::1: Connection refused Trying 127.0.0.1... telnet: connect to address 127.0.0.1: Connection refused telnet: Unable to connect to remote host

• How can I monitor VNC via Nagios?

  - by atroon

  I have a number of remote sites which have VNC running on a few computers for support purposes. They are (obviously) only available on our internal network. I am using Nagios to keep track of all the systems in the network and I want to have it check to make sure the VNC server is running on the appropriate hosts. There is a 'check_vnc' plugin available here but it relies on VNC Snapshot which I don't want to use. Certainly I could use it, but it adds more complexity and dependency, which I want to avoid. It seems simpler to just use check_tcp to make sure I get the proper response to a connection request for VNC, e.g. port 5900, send a connect string, get back framebuffer info. My real question, I suppose, is this: What is the 'proper' generic connect string for VNC (I use both UltraVNC and RealVNC) and what is the expected response? If it's really easier to use the VNC Snapshot and check_vnc, let me know. I just can't imagine that a string of text isn't easier, faster, and less bandwidth intensive to monitor.

• Setting up ssh config file with id_rsa through tunnel

  - by Rubens

  I've been struggling to set up a valid configuration to open a connection with a second machine, passing through another one, and using an id_rsa (which requests me a password) to connect to the third machine. I've asked this question in another forum, but I've received no answer that could be considered very helpful. The problem, better described, goes as follows: Local machine: user1@localhost Intermediary machine: user1@inter Remote target: user2@final I'm able to do the entire connection using pseudo-tty: ssh -t inter ssh user2@final (this will ask me the password for the id_rsa file I have in machine "inter") However, for speeding things up, I'd like to set my .ssh/config file, so that I can simply connect to machine "final" using: ssh final What I've got so far -- which does not work -- is, in my .ssh/config file: Host inter User user1 HostName inter.com IdentityFile ~/.ssh/id_rsa Host final User user2 HostName final.com IdentityFile ~/.ssh/id_rsa_2 ProxyCommand ssh inter nc %h %p The id_rsa file is used to connect to the middle machine (this requires me no password typing), and id_rsa_2 file is used to connect to machine "final" (this one requests a password). I've tried mixing up some LocalForward and/or RemoteForward fields, and putting the id_rsa files in both first and second machines, but I could not seem to succeed with no configuration whatsoever. Hope somebody can help me here! Regards! P.S.: the thread I've tried to get some help from: http://www.linuxquestions.org/questions/linux-general-1/proxycommand-on-ssh-config-file-4175433750/

• Windows VPN always disconnects after < 3 minutes, only from my network

  - by hemp

  First, this problem has existed for almost two years. Until serverfault was born, I pretty much gave up on solving it - but now, hope is reborn! I've set up a Windows 2003 server as a domain controller and VPN server at a remote office. I am able to connect to and work over the VPN from every windows client I've tried, including XP, Vista, and Windows 7 without issue, from at least five different networks (corporate and home, domain and non.) It works fine from all of them. However, whenever I connect from clients on my home network, the connection drops (silently) after 3 minutes or less. After a short while, it will eventually tell me the connection has dropped and attempt to redial/reconnect (if I've configured the client that way.) If I reconnect, the connection will re-establish and appear to work correctly, but again will silently drop, this time after a seemingly shorter time period. These are not intermittent drops. It happens every single time, in exactly the same way. The only variable is how long the connection survives. It doesn't matter what type of traffic I send. I can sit idle, send continuous pings, RDP, transfer files, all of that at once - it makes no difference. The result is always the same. Connected for a few minutes, then silent death. Since I doubt anyone has experienced this exact situation, what steps can I take to troubleshoot my evanescing VPN?

• What could be wrong with my VLAN?

  - by Matt

  I've got a VLAN 10 setup as a management VLAN. The management VLAN comes off port 48 and links to another set of switches that do not support VLAN's so it was I believe set up as an untagged access port. In the past this was a different brand of switch and this worked fine. However, since changing to the HP V1910-48G series I can't seem to get this working. I must point out that as far as I'm aware it is wired up properly (I can't check this physically as I'm working remote and have asked the tech who's got access to double check for me). Now I don't have a huge amount of experience with VLAN environments but AFAIK this is right. I've set the port 48 (linked to the management switches) as an untagged port with PVID 10 and access link type. Is this all I'd need to do from a configuration perspective to ensure all devices connected to port 48 would end up being on VLAN 10 and not needing to tag their frames. i.e. the tag would be added by the switch before being forwarded.

• How do I connect to SSH without the password to be requested every time ? - Already follow some answers here but it doesn't work

  - by MEM

  MAC OS X Lion 10.7.3 1) On host, I've created an authorized_keys file inside .ssh folder, by doing: touch authorized_keys 2) I've copy my public ssh key into host .ssh folder by doing: scp ~/.ssh/mykey.pub [email protected]:/home/userhost/.ssh/mykey.pub 3) I've place it's contents inside authorized files by doing: cat mykey.pub >> authorized_keys 4) Then I've removed the mykey.pub file: rm mykey.pub 5) On my terminal, locally, inside my ~/.ssh folder I made: ssh-add mykey (notice that it is without the pub extension); 6) I've closed and opened again the terminal. When I first connect to this host, it has being added to the *known_hosts* file inside ~/.ssh; I've pico known_hosts and the hash is there. Still, every time I connect by doing: ssh [email protected] it requests a password ! What am I missing here ? UPDATE: I've done EVEN TWO MORE THINGS here: 7) Set your key to be the default identity - if it doesn't exist, create; touch ~/.ssh/config and place inside the following line: IdentityFile ~/.ssh/yourkeyname *id_rsa is normally your default key. You should switched to your key. This tells that the outgoing ssh connections should use this as a default identity.* 8) Add a bash process to your ssh-agent: ssh-agent bash ssh-add ~/.ssh/yourkeyname Lisinge answer helped but it's not definitive. If we restart our machine, the password gets prompted again!!! How can we debug this? What can we do here? How can we check where is this process failing ? UPDATE 2: If I use: ssh -v -i <keyfile> [email protected] I get among other things: OpenSSH_5.6p1, OpenSSL 0.9.8r 8 Feb 2011 Warning: Identity file yourkeyname not accessible: No such file or directory. This message refers to what? The identify file is not accessible on the localhost, or it's not accessible on the remote host ? Please advice

• Cisco ASA user authentication options - OpenID, public RSA sig, others?

  - by Ryan

  My organization has a Cisco ASA 5510 which I have made act as a firewall/gateway for one of our offices. Most resources a remote user would come looking for exist inside. I've implemented the usual deal - basic inside networks with outbound NAT, one primary outside interface with some secondary public IPs in the PAT pool for public-facing services, a couple site-to-site IPSec links to other branches, etc. - and I'm working now on VPN. I have the WebVPN (clientless SSL VPN) working and even traversing the site-to-site links. At the moment I'm leaving a legacy OpenVPN AS in place for thick client VPN. What I would like to do is standardize on an authentication method for all VPN then switch to the Cisco's IPSec thick VPN server. I'm trying to figure out what's really possible for authentication for these VPN users (thick client and clientless). My organization uses Google Apps and we already use dotnetopenauth to authenticate users for a couple internal services. I'd like to be able to do the same thing for thin and thick VPN. Alternatively a signature-based solution using RSA public keypairs (ssh-keygen type) would be useful to identify user@hardware. I'm trying to get away from legacy username/password auth especially if it's internal to the Cisco (just another password set to manage and for users to forget). I know I can map against an existing LDAP server but we have LDAP accounts created for only about 10% of the user base (mostly developers for Linux shell access). I guess what I'm looking for is a piece of middleware which appears to the Cisco as an LDAP server but will interface with the user's existing OpenID identity. Nothing I've seen in the Cisco suggests it can do this natively. But RSA public keys would be a runner-up, and much much better than standalone or even LDAP auth. What's really practical here?

• OpenVPN - Cannot browse ipv4 websites

  - by user1494428

  I have set up an openVPN tunnel on my VPS (OpenVZ - Ubuntu 12.04). The problem is I can only browse websites which support ipv6 like google. http://whatismyv6.com/ reports me that I've an ipv6 adress, so I guess this is the problem.

• What can I do to determine the root cause of a Windows server hanging/freezing?

  - by Aaronaught

  We set up a new server here a few weeks ago that I am informally responsible for managing. Almost everything works perfectly except for one thing: Every so often it hangs without warning. To clarify: When I say hangs, I mean completely. None of the services respond and I'm unable to even get onto a local console - the display acts as though there's no VGA signal. One time, the server actually responded to pings, another time I got the "destination host unreachable" response, but most of the time the pings just time out, as one would expect for a hung server. Event logs don't show anything after a reboot. I don't mean that they don't show anything interesting, I mean that they don't show anything at all from before the failure occurs to after the reboot. And there are never any performance problems, strange errors, or other obvious signs of impending doom before it happens. I don't expect any easy answers here. What I'd like to know his I can methodically determine the root cause of this problem, be it a misbehaving service, defective hardware, or something else. Is there any kind of logging I can set up that will help me get to the bottom of this? Any hardware diagnostics or remote monitoring? Anything else I can do to help me discover what's actually happening, or at least be able to eliminate what isn't wrong? Just to reiterate, I really don't want to start speculating about possible causes and take a trial-and-error approach, because it's going to be at least several days at a time before I would have conclusive results. I'm looking for solutions to reliably trace the problem to its source.

• Power Outage Interrupted Upgrade from Windows Vista Ultimate to 7 Ultimate, Reverted to Vista, Now Vista is failing... What Next?

  - by tednewk

  I was in the midst of what seemed to be a successful upgrade from Vista Ultimate to 7 Ultimate when there was a brief blackout. The upgrade failed and Windows reverted back to Vista. Now Vista is very slow to boot, has problems waking back-up from inactivity and quickly loses it's wireless connection. The wake-up problem manifests itself as the mouse is clearly shown on a black screen but I have no access to the Desktop or Taskbar or Explorer. Even Alt-Ctrl-Delete doesn't seem to work. No task menu, no reboot. Hitting the reset button reboots the machine with the usual Black Screen warnings offering Safe Mode. I tried to do a system restore to a point before the upgrade. That didn't seem to work. My guess is that my system is a mutant with parts of Vista and parts of 7 crashing each other. I would like avoid a clean install if at all possible to avoid reinstalling other software. What should I try now? My thoughts are: My a system back-up to lock the computer in place Trying a second 7 upgrade If that appears to be working make another back-up If not reload back-up and try a repairing Vista from DVD. If that appears to work make another back-up, let system stablize about a week then try 7 install again If that doesn't work are there any other options to try before settling for a clean install? Another complication, I am doing this by "remote control". I'm traveling with my job and I'll be talking my son through it over the phone. (Kind of like the landing the 747 cliche from all the 70's adventure shows!) So is there a way of simplifying the steps? Thanks Ted

• Device CAL, User Cal or Processor license needed for SQL 2008 (architecture explained inside)?

  - by nycgags

  So we have a number of servers in the Amazon cloud running SQL Server Standard edition to aggregate data. For that purpose we are fine, the licensing is handled by our contract with Amazon, no problem there. For the beefier work, we want to install Enterprise Edition (EE) on our servers processing raw data so that we can take advantage of table partitioning. We currently have 3 servers aggregating data from about 40 node servers, all 43 of these servers are running standard edition which is fine. We also have 4 servers running standard processing the raw data, but I think we can get away with 2 (for redundancy) running Enterprise Edition. We have 2-3 dba's that access these DW servers for maintenance (using the same windows login via remote desktop). So visually: 40 -- 3 -- [2] -- 2 -- 1 nodes -- aggregators -- raw (which we want to run EE) -- calculators -- datawarehouse Nodes PUSH to aggregators, Raws PULL from aggregators, Calculators PULL from Raw, Calculators PUSH to datwarehouse I am specifying the push vs. pull in case that changes how the # of licenses is calculated. Q1) how many device (or user) CAL's do we need? Q2) do I need to speak with someone from MSFT to find out if it is ok to install in the Amazon Cloud (Amazon said we need to verify it is ok in our license terms)? Q3) what happens if another device tries to access a server with the limited number of device CAL's? Q4) Are the device CAL's simultaneous number of devices or total? Q5) Do Device and User CAL's cost the same or is there a difference? Q6) Would we need to buy a processor license (we are hoping not to)?

• Random server lag, no CPU/mem/pagefile usage

  - by Kev

  We have a fairly new server running Windows 2003 SP2, and the past few days we've noticed random slowdowns. When I'm logged into the server over remote desktop while this is happening, or if I'm physically sitting at the server logged in, suddenly everything becomes extremely laggy. Any UI element I try to interact with takes upwards of ten seconds to react, and then responds very slowly. Then a minute later everything is quite snappy again. During this, I have Task Manager minimized to the tray, and there's no CPU usage. I open it up right after this happens, and there's very little CPU usage on the graph, and no memory or pagefile usage above normal. (Normal being 1.5 GB free in the case of memory.) This is what I see logged into the server, and then users start calling saying things are slow, timing out, and failing--anything to do with our server. No events in the Event Viewer around the times this happens. The context I'm working in (last thing I clicked, etc.) seems different every time--different programs active, different combinations of programs open. Never anything particularly stressful (like adding an event entry to a Cobian Backup configuration, or editing text in TextPad, which has been exceptionally stable in my extensive usage of it.) I would've thought it was just the server, but a family member's home PC (entirely separate) running WinXPSP3 had the same thing happen to it last night a few times. Is this some new behaviour introduced by the latest Windows Updates? Either way, where do I even start to look when nothing seems to be chewing up resources?

• ApplicationPoolIdentity IIS 7.5 to SQL Server 2008 R2 not working.

  - by Jack

  I have a small ASP.NET test script that opens a connection to a SQL Server database on another machine in the domain. It isn't working in all cases. Setup: IIS 7.5 under W2K8R2 trying to connect to a remote SQL Server 2008 R2 instance. All machines are in the same domain. Using the ApplicationPoolIdentity for the web site it fails to connect to the SQL Server with the following: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.Data.SqlClient.SqlException: Login failed for user 'NT AUTHORITY\ANONYMOUS LOGON'. However if I switch the Process Model Identity to NETWORK SERVICE or my domain account the database connection is successful. I've granted the \$ access in SQL Server. I am not doing any sort of authentication on the web site, it is just a simple script to open a connection to a database to make sure it works. I have Anonymous Authentication enabled and set to use the Application pool identity. How do I make this work? Why is the ApplicationPoolIdentity trying to use ANONYMOUS LOGON? Better yet, how do I make it stop using the Anonymous logon?

• Installing sphinx on a web hosting server

  - by fiftyeight

  I want to install sphinx search on a web-hosting server. I'm on a Linux VPS with hostgator, but I never actually installed anything on a remote server so this will be a first time for me. If there's anyone here who installed sphinx it's really help me I had some problems when using sphinx on my PC with the permissions and the MySQL files, eventually I got it working on my PC. Anyway, I'd me really grateful if anyone can help me with some questions Do i need root access to install sphinx? I have root access to the server but I'd connect to it as a normal user since doing stuff as root is always less secure. can anyone tell me by what user I need to execute the indexer and the search daemon? Should I use root access in order to this? when I did it as a normal user on my PC it gave me some trouble with the PID file and the log files. last time I executed the search deamon I executed it as a normal user and it gave me some trouble, I created the folder /var/log/ for log files and did chmod 777 on it, but still when I executed the search daemon it created the PID file "searchd.pid" file but with no permissions for some reason, any idea why? Thanx in advance. fiftyeight

• LXC, Port forwarding and iptables

  - by Roberto Aloi

  I have a LXC container (10.0.3.2) running on a host. A service is running inside the container on port 7000. From the host (10.0.3.1, lxcbr0), I can reach the service: $ telnet 10.0.3.2 7000 Trying 10.0.3.2... Connected to 10.0.3.2. Escape character is '^]'. I'd love to make the service running inside the container accessible to the outer world. Therefore, I want to forward port 7002 on the host to port 7000 on the container: iptables -t nat -A PREROUTING -p tcp --dport 7002 -j DNAT --to 10.0.3.2:7000 Which results in (iptables -t nat -L): DNAT tcp -- anywhere anywhere tcp dpt:afs3-prserver to:10.0.3.2:7000 Still, I cannot access the service from the host using the forwarded port: $ telnet 10.0.3.1 7002 Trying 10.0.3.1... telnet: Unable to connect to remote host: Connection refused I feel like I'm missing something stupid here. What things should I check? What's a good strategy to debug these situations? For completeness, here is how iptables are set on the host: iptables -F iptables -F -t nat iptables -F -t mangle iptables -X iptables -P INPUT DROP iptables -P FORWARD ACCEPT iptables -P OUTPUT ACCEPT iptables -A INPUT -p tcp --dport 22 -j ACCEPT iptables -A INPUT -p icmp --icmp-type echo-request -j ACCEPT iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT iptables -t nat -A POSTROUTING -o eth0 -j MASQUERADE iptables -t nat -A POSTROUTING -o lxcbr0 -j MASQUERADE iptables -t nat -A PREROUTING -p tcp --dport 7002 -j DNAT --to 10.0.3.2:7000

• Help trying to figure out why IIS7 is crashing / locking up / denying connections

  - by Pure.Krome

  Hi folks, I've got a pretty busy website that is running on a single web front end machine, on W2K8 + IIS7. Every now and then - eg. maybe monday at 3am or something, then a few days later .. some early morning time .. then nothing for 2 weeks ... etc - the website fails to respond to any client connections. ie. no one can connect to the website. I can remote desktop to the machine, etc no probs. I restart the app pool (the website is running in intergrated mode), still nothing. I try and get a crash dump of the process (it's around 600 mb maybe even more) ... that fails after about a min of trying (and i have plenty of HD space). The only way to fix this issue, is to manually stop the www service and then start it again. The stopping takes a while (a minute?) while starting is nearly instant. I'm at a loss to figure out what part of my code is causing this. At first, I thought it might be a stack overflow because of some error that might be going to the error page, which in turn errors .. rinse repeat boom. But i've had a look at the error page and it feels ok. So, I'm hoping someone might be able to help and say how I can correctly get a proper dump of the IIS process so i can then do some more autopsy on it. I would email Tess Ferrandez (the goddess of crash debuging) but I thought I'd try here before I spam her. Can anyone have any suggestions to how I can figure out how to start to debug this issue?

• logrotate: neither rotate nor compress empty files

  i have just set up an (r)syslog server to receive the logs of various clients, which works fine. only logrotate is still not behaving as intending. i want logrotate to create a new logfile for each day, but only to keep and store i.e. compress non-empty files. my logrotate config looks currently like this # sample configuration for logrotate being a remote server for multiple clients /var/log/syslog { rotate 3 daily missingok notifempty delaycompress compress dateext nomail postrotate reload rsyslog >/dev/null 2>&1 || true endscript } # local i.e. the system's very own logs: keep logs for a whole month /var/log/kern.log /var/log/kernel-info /var/log/auth.log /var/log/auth-info /var/log/cron.log /var/log/cron-info /var/log/daemon.log /var/log/daemon-info /var/log/mail.log /var/log/rsyslog /var/log/rsyslog-info { rotate 31 daily missingok notifempty delaycompress compress dateext nomail sharedscripts postrotate reload rsyslog >/dev/null 2>&1 || true endscript } # received i.e. logs from the clients /var/log/path-to-logs/*/* { rotate 31 daily missingok notifempty delaycompress compress dateext nomail } what i end up with is having is some sort of "summarized" files such as filename-datestampDay-Day and corresponding .gz files. What I do have are empty files, which are eventually zipped. so does the notifempty directive is in fact responsible for these DayX-DayY files, days on which really nothing happened? what would be an efficient way to drop both, empty log files and their .gz files, so that I eventually only keep logs/compressed files that truly contain data?

• Whats the best cloud backup solution for a small scale server envoirnment?

  - by nbv4

  I have a server that runs a postgres database that contains about 200MB of data. Currently I have a cron job setup on my home computer which: ssh's into my server runs a remote script which makes a backup of the database scp's that dump over to my local hard drive for storage. Each dump is 20MiB. does this every six hours (one months of backups is roughly 2GiB) The problem with this setup is that if my local machine goes down for whatever reason, no backups will be made. Also, I can't have the cron run from the server, because I can't have it scp'd to my local machine from my server (firewalls and all that crap). My local machine is running Ubuntu 10.04, and my server is Ubuntu 9.10 server edition. I looked into Ubuntu One, but currently it's gui-only. I also looked into dropbox, but it's a pain in the ass to get setup in linux without gui support. Amazon S3 looks good but it's not free (yet dirt cheap). Is there any other alternative that I should look into? I'd prefer something where I can just have my script dump the database into a directory, and have the backup service 'watch' that folder and sync accordingly. I can maybe also have my local machine sync to the cloud backup so I have even more redundancy, plus easy access to my backups for use in testing.

• Configuring IE to resolve DNS at the proxy rather than locally.

  - by dankilman

  With the intention of tunneling web traffic through an SSH connection, the following has been done: I've manually configured a PAC file in IE7 in the LAN Settings dialog. I've verified that traffic is routed through my SSH tunnel that is setup for SOCKS5 dynamic port forwarding. I see that IE7 is always trying to resolve the name locally first. What I'm looking for is the ability to have the DNS name resolved at the proxy, rather than locally by the browser. There's a setting in Firefox that specifies DNS remote resolution, and Safari does it automatically. I've verified correct operation for these 2 other browsers. It would be nice if I could get IE to work also. This is for reference so you could understand where does the question originate from. Notice: The question was actually found by the help of google but with no answers available. Considering how it is exactly my question I figured I should just copy/paste over here because I don't think I could describe any better (there is a small introduction though).

• Connection timed out on Node.js app running under CentOS

  - by ss1271

  I followed this tutorial to create a simple node.js app on my CentOS: the node.js version is: $ node -v v0.10.28 Here's my app.js: // Include http module, var http = require("http"), // And url module, which is very helpful in parsing request parameters. url = require("url"); // show message at console console.log('Node.js app is running.'); // Create the server. http.createServer(function (request, response) { request.resume(); // Attach listener on end event. request.on("end", function () { // Parse the request for arguments and store them in _get variable. // This function parses the url from request and returns object representation. var _get = url.parse(request.url, true).query; // Write headers to the response. response.writeHead(200, { 'Content-Type': 'text/plain' }); // Send data and end response. response.end('Here is your data: ' + _get['data']); }); // Listen on the 8080 port. }).listen(8080); However, when I uploaded this app onto my remote server (assume the address is 123.456.78.9), I couldn't get access to it on my browser http://123.456.78.9:8080/?data=123 The browser returned Error code: ERR_CONNECTION_TIMED_OUT. I tried the same app.js code which runs fine on my local machine, is there anything I am missing? I tried to ping the server and its address was reachable. Thanks.

• Pushing Windows Store apps silently

  - by seagull

  As part of a requirement I have been issued, I seek the ability to push apps from the Windows Store (.appx) to remote users. The framework surrounding the data transmission is sorted; What I need to know is if there is a script that can be sent out along with a URI or the package proper to facilitate installation on the user-side of the Windows Store app. I am well aware that numerous guides exist from Microsoft on pushing out Line-of-Business (LOB) (AKA Enterprise) applications -- that is, apps that have been developed in-house and are not for the consumption of the Windows store. This is inappropriate for my requirement, however; the customer wants their clients to receive apps that appear currently on the Windows Store, and for them to be installed in a silent manner. I've seen this guide; http://blogs.technet.com/b/keithmayer/archive/2013/02/25/step-by-step-deploying-windows-8-apps-with-system-center-2012-service-pack-1.aspx, which details doing exactly this, but it is only applicable to machines that are administered by a system running Windows Server 2012 R2 with the 'System Center 2012' bundle installed. The systems I target are considerably more decentralised than this, making this guide inappropriate. I have a hunch that Microsoft have deliberately designed the Windows Store to be this way, but I figured I ought to ask around before I resign myself to the requirement. Much obliged
