• Running a VM off a USB 2.0 Flash Drive - Mac/Parallels/XP

  - by geerlingguy

  I use a MacBook Air as my primary machine, and the 128GB SSD means space is precious. To save about 10 GB, I've been running Parallels with a Windows XP VM off an external USB hard drive, which performs as well in everyday use as running the VM off the internal SSD. So, I bought a tiny 32GB USB 2.0 flash drive, plugged it into the MacBook Air, formatted it first as ExFAT (which was slow), then as Mac OS Extended (Journaled) (which was also slow), and copied over my VM file, and ran Parallels off it. My full experience is documented here: http://www.midwesternmac.com/blogs/jeff-geerling/running-windows-xp-vm Straight file copies are really fast — 30 MB/sec read (solid the whole time), and 10-11 MB/sec write (solid the whole time). But I noticed that once XP started running, the disk access rates were in the low KB ranges. Are USB flash drives really that poor at random access, or could I possibly be missing something (the format of the flash drive, etc.?)? Of note, I've tried the following, to no great effect: Formatting the drive as either ExFAT or Mac OS Extended (Journaled) Unplugging all other USB devices and turning off Bluetooth (which runs on the right-side-port USB bus). Plugging in the flash drive either direct in the right side port, or the left side port, or into a USB 2.0 hub

• Windows Server 2008 R2 RAS VPN: access server on internal interface ip

  - by Mathias

  Hey, short question: I'm usually a linux admin but need to setup a Win2k8 R2 server for a student project. The server is running as VM on a root server and has a public internet IP assigned. Additionally I need a VPN server to access some services running on the server. I managed to set up a working VPN gateway via the Routing and RAS service which assigns clients an IP in the private subnet 192.168.88.0/24 with the Interface "Internal" listening on 192.168.88.1. Additionally I set up the external interface as NAT interface. So I can connect to the VPN server, get an IP assigned and the server additionally does NAT and I can access the internet over the VPN connection. The only thing I additionally need, is that I can access the server itself over that internal IP (e.g. client 192.168.88.2, server 192.168.88.1) as I want to access some services which I don't like to expose to the internet and restrict them to connected VPN clients. Does anybody have a hint, which configuration I'm missing here to be able to access the server over the VPN connection? EDIT: VPN clients get assigned the IP from the private subnet with subnetmask 255.255.255.255, I guess that might be the reason I can't access the server on the private IP address although it's in the same network range. Any ideas how to change this? I defined a static address pool in the Routing and RAS service, but I can't change the netmask there. EDIT2: I can't access the server from the client, but I can fully access the client from the server (ping, HTTP). I guess it has to do with firewall configuration. Thanks in advance, Mathias

• 2nd instance of mysql closes/doesnt start no warnings/errors?

  - by acidzombie24

  I have an external HD and i'd like to run a 2nd mysql instance on it. I used the windows installer to install/configure mysqld as a service on windows7. I took the my.ini from C:\Program Files\MySQL\MySQL Server 5.5\my.ini Then edited the port (client and mysqld), datadir and innodb_data_home_dir. After running this command "C:\Program Files\MySQL\MySQL Server 5.5\bin\mysqld" --defaults-file="f:/dev/my.ini" I found an error which was all about the innodb_data_home_dir directory not existing. After that I ran the command again. Mysqld simply starts up for a second then immediately closes. I see no message in my command prompt. I know this command line args are correct as i see the mysqld service using the same one except a different my.ini path. Also it did tell me about the directory not existing so i know it is reading the new ini file. How do i figure out why this 2nd instance of mysqld is closing? How do i get 2 instance running? I'm using v 5.5

• Will just a couple of thermal "trip" shutdowns typically damage a CPU?

  - by T.J. Crowder

  The short version If a CPU gets so hot that the system turns itself off because of a thermal trip signal just a couple of times, is it likely that the CPU will be damaged? Or does the trip do its job, turning it off before the CPU gets damaged? (This is with all default settings in the BIOS; I haven't raised any temp thresholds or overclocked anything.) The longer version I just got this Intel Atom D510-based fanless system, installed a 2.5" mobile SATA drive and two 2GB PC2-6400s, closed it up, and having checked everything was recognized in the BIOS, set about installing Ubuntu. After a couple of false starts related, I think, to the external DVD drive I was using, I got the install happily running along. About three-fourths or so of the way through the install, having been running less than an hour, the machine turned itself off. I was actually out of the room at the time, but when I came back and turned it back on, it said it had shut down due to a thermal event. I went into the BIOS and saw that (at that point, having just been turned back on after a couple of minutes off), it was running 87C. As near as I can tell from Intel's docs (PDF here), the max "junction" temperature for the CPU is 100C and it will raise a THERMTRIP signal at 125C. Yowsa. Presumably there will be some back-and-forth with the vendor on this, I'm just wondering whether letting it get that hot a couple of times is likely to end up damaging it.

• Where in the stack is Software Restriction Policies implemented?

  - by Knox

  I am a big fan of Software Restriction Policies for Microsoft Windows and was recently updating our settings for this. I became curious as to where Microsoft implemented this technology in the stack. I can imagine a very naive implementation being in Windows Explorer where when you double click on an exe or other blocked file type, that Explorer would check against the policy. I call this naive because obviously this wouldn't protect against someone typing something in a CMD window. Or worse, Adobe Reader running an external application. On the other hand, I can imagine that software restriction policies could be implemented deep in the stack almost at the metal. In this case, the low level loader would load into memory the questionable file, but mark the memory in the memory manager as non-executable data. I'm pretty sure that Microsoft did not do the most naive implementation, because if I block Java using a path block, Internet Explorer will crash if it attempts to load Java. Which is what I want. But I'm not sure how deep in the stack it's implemented and any insight would be appreciated.

• Correct way to set up office network - 8 workstations, a file server and a staging server

  - by naunu

  Our office had this old school windows 2003 domain setup, our server caught fire, and now we are looking to do it right from scratch. Here is what we need: 5 PC and 3 Mac workstations for web development, they will each have WAMP/MAMP setup on them, managed by their developers. We will have a file server for assets, and a LAMP server with an external IP for staging. Here is what we have to work with: 5 IP addresses, brand new PC file server with windows 2008 SE, D-Link DSS-16+ 16 port switch, belkin 5 port wireless router, cable modem with 4 ports. How I have it set up now (this is a temporary makeshift setup): Cable modem = LAMP server, wireless router Wireless router = Switch = All of the workstations and file server (setup as a workgroup). We have noticed our internet is very slow with us all plugged in to the switch, and the switch plugged in to the router. I am not positive, but I think it is because our router does not have NAT. We are also having problems with the MACs connection to the network drive - it keeps disconnecting. I want this done right, and we have a ~$600 budget to buy anything else we need. Does anybody have any advice for me? Should I set up a domain or workgroup?

• Apache mod_proxy with SSL not redirecting

  - by simonszu

  I have a custom server running behind an apache reverse proxy. Since the custom server can only handle HTTP traffic, i am trying to use apache for wrapping proper SSL around it, and for some kind of HTTP authentication. So i enabled mod_proxy and mod_ssl and modified sites-available/default-ssl. The config is as following: <Location /server> order deny,allow allow from all AuthType Basic AuthName "Please log in" AuthUserFile /etc/apache2/htpasswd Require valid-user ProxyPass http://192.168.1.102:8181/server ProxyPassReverse http://192.168.1.102:8181/server </Location> The custom server is accessible from the internal network via the location specified in the ProxyPass directive. However, when the proxy is accessed from the outside, it presents the login prompt, and after successfully authenticated, i get a blank page with the words The resource can be found at http://192.168.1.102:8181/server. When i type the external URL again in an already authenticated browser instance, i am properly redirected to the server frontend. The access.log is full of entrys stating that my browser does successful GET requests, and the proxy is happily serving the /server ressource. However, the ressource isn't containing the server's frontend, but this blank page with these words on it.

• Need help with MS Access 07 & Reports

  - by Moe

  Hey there, I'm finding it difficult to get MS reporting working to what I'd like to show. What I'm trying to do is: a) In my database store a URL file (HTTP external file), that is a .jpeg. I'd like to use that URL to call the image on the report sheet. I have tried to use 'Control source' on the data panel, but with no success. Any way I can get Dynamic Images to show up on each database. Also, I have a couple of Relational Databases. One Defines Values: For Example: DefinePets('petID','Name of Pet') The other one links the Main DB with the 'DefinePets' database. Eg: connect('petID','mainID','extraFeild') I'd like my report to Go into the "connect" Table, where the the currently viewed Record Value = mainID, then find petID and return Name of Pet. There is a many to many link between definePets and the main Table. (Therefore connect is joining them up) Or is that too much to ask from a simple package like Access? Thanks.

• Use Mac OS X Server As Development Environment

  - by macinjosh

  I've installed Mac OS X Server 10.6.3 on my laptop to use as my normal OS. I do a lot of web development and thought it would be handy to run OS X Server so I could more easily manage my local development environment (Apache Virtual Hosts, Hostnames for each local site, etc). I'm really enjoying the new setup except for one problem. DNS. My ideal situation would be to add a site (some-site.local) in the Web Service and then go to the DNS Service and add a primary record for the new site. I actually got this working at one point but after a reboot it stopped working! The records look the same as they did before the reboot but the site doesn't come up in Safari. Here is a list of my needs: Need to be able to add new domains at a whim Domains always map to a site on the same box's Web Service Local & External IPs often change It would nice if it worked on any network (i.e. WiFi at the airport or coffee shop) Sites only need to be accessible locally Configuration should stay put even after rebooting I've done some googling and used this as a bit of guide. In the past I've used MAMP and then just a local Apache/PHP/MySQL install with a manually managed hosts file. I'd rather not go back.

• What permission(s) does an application pool identity required to manage other application pools?

  - by Mr Shoubs

  I have a web site (used to manage various parts of our software) that needs the permissions required to start/stop other application pools. I've created a user and set the app pool identity to custom, however the web app still can't start/stop the app pools. I get the following Error: System.UnauthorizedAccessException: Filename: redirection.config Error: Cannot read configuration file due to insufficient permissions at Microsoft.Web.Administration.Interop.AppHostWritableAdminManager.GetAdminSection(String bstrSectionName, String bstrSectionPath) at Microsoft.Web.Administration.Configuration.GetSectionInternal(ConfigurationSection section, String sectionPath, String locationPath) at Microsoft.Web.Administration.ServerManager.get_ApplicationPoolsSection() at Microsoft.Web.Administration.ServerManager.get_ApplicationPools() Discussion here suggests setting the application pool to local system or administrator, this does work, but I don't want to do this for security reasons (external support will need access this site). I did give the user higher permissions (as suggested here), starting by making it part of the local administrators group, but initially this didn't work, and giving the user read/write/mod permission on C:\Windows\System32\inetsrv\config also didn't work. I must have done something wrong as local administrator now works, however this still isn't what I want. So can anyone suggest the permissions I need to add to this user, and how can I apply them? An answer my problem (but different question) is here, but to clarify, I think I need to give an individual user "IIS Runtime Operation Permissions", does anyone know how to do this, if indeed this is the permissions I require?

• Webservice randomly dropping connections - possibly due to firewall nonevent data?

  - by adam

  I have a hosted webapp which requests data from a REST webservice in our office. Each page calls one (or several) webservices, which go from our host, via our firewall (a Watchguard Firebox) to a server in our office. All of a sudden, the app has dramatically slowed. We have determined that the webservice is timing out at random when called externally (it's fine when called within the office network). I'm pretty certain it's our connection which is dropping the webservice call, so I've written a quick php/curl script which calls the webservice over many iterations and shows the various timings. Below is an example output, showing both a failed and a successful call (with a 5 second timeout): http_code namelookup_time connect_time pretransfer_time starttransfer_time total_time 1 0 0.000096 0.0342 0.0000 0.0000 0.0342 2 200 0.000052 0.0332 0.1327 0.1751 0.1752 As per iteration #1 above, failed requests seem to be failing between connect and pretransfer. I'm not sure if this shows that the connection is successfully past the firewall, or could the firewall still cause an issue? Our firewall is showing a series of nondata event log messages for the relevant access rule. Our IT team tells me these are routine, although I can find no mention of these in Google. I'm not sure if this fits in between connect and pretransfer. Having elinated the webservice server (by testing internally) and the live webapp (by testing different code on different external servers, I am left suspecting the connection to the office. Could the firebox nondata events be causing a problem between connect and pretransfer?

• Sonicwall TZ210 - Set up public wifi on separate subnet & interface

  - by thomasjbarrett

  I want to set up a public wifi by connecting another router to the X6 interface, and put it on a separate subnet (192.168.10.0/24) & in the DMZ Zone to keep it away from the regular LAN. I believe I have the network settings correct: the router has acquired the IP and DNS information from the TZ210, and the TZ210 shows it as an active DHCP lease. X6 is in the DMZ. I now have a routing/NAT/firewall problem, since I can't get any traffic to travel from the subnet to the internet. I can't get to any external websites and can't ping the TZ210 from the subnet. X0 is the regular LAN, and X1 is the WAN. Looking for any tips or tutorials on this. Here's my current relevant rules: Routing Source: X6 Subnet Destination: Any Service: Any Gateway: Default Gateway Interface: X6 Source: Any Destination: X6 Subnet Service: Any Gateway: 0.0.0.0 Interface: X6 NAT Policies Source Original: Any Translated: WAN IP Destination Original: Any Translated: Original Inbound: X6 Outbound: X1 Source Original: Any Translated: U0 IP Destination Original: Any Translated: Original Inbound: X6 Outbound: U0 Firewall DMZ LAN : Deny All DMZ WAN : Allow All LAN DMZ : Allow All WAN DMZ : Allow All

• Referencing groups/classes from Puppet dashboard in my site manifest

  - by Banjer

  I'm using Puppet Dashboard as my ENC and I'm not sure how to reference or use class and group classifications from /etc/puppet/manifests/site.pp. I have two groups defined in the dashboard: CentOS6 and SLES11. What should my site.pp look like if I want to include a certain list of modules in the CentOS6 group and a certain list of modules in the SLES11 group? I'm trying to do something like this: # /etc/puppet/manifests/site.pp node basenode { include hosts include ssh::server include ssh::client include authentication include sudo include syslog include mail } node 'CentOS6' inherits basenode { include profile } node 'SLES11' inherits basenode { include usrmounts } I have OS-specific case statements within my modules, but there are some modules that will only be applied to a certain distro. So I suppose I have two questions: Is this the best way to apply modules/resources in an OS-specific manner? Or does the above make you want to vomit? Regardless of #1, I'm still curious as how to reference classes, groups, and nodes from Dashboard within my manifests. I've read the External Nodes doc, but I'm not seeing how they correspond to manifests. Thanks all.

• Trouble with IIS SMTP relaying to Gmail

  - by saille

  I appreciate that similar questions have been asked about how to setup SMTP relaying with IIS's virtual SMTP server. However I'm still completely stumped on this problem. Here's the setup: IIS 6.0 SMTP server running on Win2k3 box with a NAT'ed IP. Company uses Gmail for all email services. An app on the box needs to send email, so normally we'd just set the app up to talk to smtp.gmail.com directly, but this app doesn't support TLS. Easy, we just setup a local SMTP relay right? So I thought. What we have done so far: Setup IIS SMTP server to relay to smtp.gmail.com, as per these excellent instructions: http://fmuntean.wordpress.com/2008/10/26/how-to-configure-iis-smtp-server-to-forward-emails-using-a-gmail-account/ The local SMTP relay allows anonymous access. Both the local IP and the loopback IP have been explicitly allowed in the Connection and Relay dialogs. Tried sending email from 2 different apps via the local SMTP server, but failed (the emails end up in the Queue folder, but never get sent). The IIS logs show the conversation with the local app, but zero conversation happening with smtp.gmail.com. The port used by gmail is open outbound, and indeed the apps we have that support TLS can send email directly via smtp.gmail.com, so there is no problem with the network. At this point I changed the smtp settings in IIS SMTP server to use a different external SMTP server and hey-presto, the local apps can send email via local IIS SMTP relay. So smtp.gmail.com fails to work with our IIS SMTP relay, but another 3rd party SMTP service works fine. We need to use smtp.gmail.com, so how to troubleshoot this one?

• Why do most songs in my media collection play twice? - Corrupt media?

  - by Dean

  Problem: Whether I'm playing the media with Rhythmbox on Ubuntu, Winamp on Windows, or my Nokia N95's media player, most of my audio files (OK, maybe only 40%) play twice. Info: I have a 500GB external 2.5" WD HDD, with a 150GB primary FAT32 partition labeled MUSIC. Inside this, I have about 500 folders containing about 10,000 MP3/WMA/M4A/WAV files. I manage the drive using Ubuntu 9.10, and frequently copy data to/from it using RSYNC, or on windows, TotalCopy. The visual output is different in each media player, but it behaves as if the 1 MP3 has the same song on it twice, and as soon as it ends it begins again. Winamp shows that the song goes for 2x as long as it should, The N95's media player shows the progress bar off the right-hand-side of the screen when it begins playing (then jumps back to the left, then continues along...). Rhythmbox doesn't show me how long the song is, nor does the progress bar move along the screen. Plea: It seams to me somewhere along the lines my collection has become corrupt... but where? And how? and please someone tell me I can fix it!! TIA, Dean.

• How to move a sata drive to a machine without AHCI mode

  - by Andrew Cooper

  I've got a Dell Inspiron 1545 on which the screen has died. I'm able to plug an external monitor into the Inspiron 1545 and it works fine, so the screen is the only issue. The OS is Win7. I'm trying to move the disk to a spare Dell Precision M90 laptop that I've got lying around. The problem is that almost as soon as the Windows logo appears in the boot sequence I get a BSOD with a STOP 0x0000007B message. Researching this message pointed to issues with SATA AHCI mode. I looked in the BIOS of the Inspiron 1545 and the controller was set to AHCI mode. I set it to ATA mode and tried to boot with the same drive and got the same result as on the Precision M90. Switching back to AHCI allowed the machine to boot correctly again. I checked the BIOS on the Precision M90 and it doesn't seem to support AHCI mode, although it is a SATA controller onboard. The BIOS is the latest A08 version available from Dell. Is there any way I can get this drive to boot in the M90 without reformatting it?

• How do I configure custom URL handlers on OS X?

  - by cwd

  I've been reading a lot online about custom URL handlers / custom protocol handlers such as: Launching External Applications using Custom Protocols under OSX OS X URL handler to open links to local files I get that you can tell the system that a particular program is able to handle a certain scheme / protocol with the Info.plist file: <key>CFBundleURLTypes</key> <array> <dict> <key>CFBundleURLName</key> <string>Local File</string> <key>CFBundleURLSchemes</key> <array> <string>local</string> </array> </dict> </array> <key>NSUIElement</key> <true/> But if there are multiple applications that are capable of opening the same URL handler, such as mailto: how do you specify which one you want the system to use? There were some references to utilities like the More Internet preference pane which no longer seems to be available from the author's site. I did find it online by Googling but it seems a bit shaky - like it was written for an older OSX - perhaps Tiger. I haven't been able to find information on how to set the URL handler for protocols and custom protocols. I'm assuming there is a plist file somewhere that I can edit - or maybe there is a newer, better utility that works well with Mountain Lion?

• Exchange 2007 relay from sendmail, message "Undelivered". Possible reasons?

  - by garlicman

  Note: This is my re-post from Stackoverflow. I've been messing with a test environment for security purposes where a DMZ RHEL5 sendmail server is used as a relay for an Exchange 2007 server. Exchange is working in the environment, I have Vista and XP VMs using Outlook on the Domain to send e-mail to each other. I've been trying to simulate an external internet VM sending an e-mail to the DMZ sendmail relay, which forwards to the Exchange server. Before everyone thinks this is too big a problem/question, I've followed the sendmail/Exchange guides and all I want to know is how I can determine why a relayed message/e-mail in Exchange is "Undelivered". Basically I send a SMTP message to the sendmail server, which relayed to my Exchange. The /var/log/maillog shows the e-mail being relayed to Exchange. Nov 17 13:41:22 externalmailserver sendmail[9017]: pAHIfMuW009017: from=<[email protected]>, size=1233, class=0, nrcpts=1, msgid=<[email protected]>, proto=ESMTP, daemon=MTA, relay=[10.50.50.1] Nov 17 13:42:17 externalmailserver sendmail[9050]: pAHIfMuW009017: to=<[email protected]>, delay=00:00:55, xdelay=00:00:36, mailer=relay, pri=121233, relay=mailserver.xyz.local. [192.168.1.20], dsn=2.0.0, stat=Sent (<[email protected]> Queued mail for delivery) This is good, but the To never receives the e-mail from Exchange. So I started poking around Exchange. In the "Message Tracking" Troubleshooting Assistant I queried the processed messages and found this: (I had to copy and paste the cells... sorry for the format) 2011/11/17 RECEIVE SMTP <[email protected]> "Undelivered Mail Returned to Sender" [email protected] [email protected] 192.168.100.10 MAILSERVER\DMZ Relay [email protected] I just want to know if anyone has any suggestions on why the DMZ Relay Connector I setup isn't relaying and is instead returning the forwarded e-mail to sender as Undelivered? My Exchange Relay Receive Connector is pretty simple. The Exchange server's FQDN is set as the HELO response, all available IP addresses can receive relayed e-mail, and the IP address of my sendmail server is specifically set as a remote server.

• Warning for "Reallocated Event Count" S.M.A.R.T. attribute with a new/unused drive. How serious is t

  - by Developer Art

  I've just looked at the health status of my old 2,5 inch 500 Gb Fujitsu drive with a popular "HD Tune" utility. It shows a warning for the "Reallocated Event Count" property. How serious is that? The thing is that the drive is practically new. I pulled it out of a new laptop over a year ago and never used it since. Right now it only has 53 "Power On" hours which sounds about right since I only had it running a few evenings overnight before switching it for something more performant. Does this warning indicate that the drive is likely to fail some time in the future? I'm somewhat perplexed since the drive is effectively unused. What is more, I have arranged with somebody to buy off this drive since I don't really need. It is 12,5 mm thick (with 3 plates) meaning it doesn't fit into an external enclosure which makes it quite useless to me. Can I give away the drive without having it on my conscience or better cancel the deal? In other words, can the drive be used safely for years to come or better throw it away? I'm running a sector test now to see if there are any real problems. Will post the results as soon as they're available.

• CNAME rule being ignored

  - by Ben

  On a server with Plesk installed I have added a CNAME rule pointing from one of the sites subdomains to an external website. I have checked the named configuration for that domain name and it shows the CNAME however the sub domain just points to the default server page and ignores the CNAME rule. Named has been restarted and I've also run the rvmng reconfigure-vhost command. I edited another server to test this, on cPanel, and it works fine. The conf file for the domain: ; *** Ts file is automatically generated by Plesk *** $TTL 86400 @ IN SOA ns.example.com. cf.example1.com. ( 1292946742 ; Serial 10800 ; Refresh 3600 ; Retry 604800 ; Expire 10800 ) ; Minimum example.com. IN NS ns.example.com. ns.example.com. IN A xx.xxx.xxx.xx example.com.

IN CNAME example.com. login.example.com. IN CNAME socialize.gigya.com. example.com. IN MX 10 webmail.example.com. You can see the CNAME rule in the file but it just gets ignored? Thanks in advance for any help.

• exFAT to NTFS formatting troubles

  - by user1083734

  I recently ran a chkdsk on 2.5" 230GB SATA HDD but the plug was pulled before the end of the chkdsk and since then it wouldn't boot up. Deciding to scrap all data on the HDD (no longer needed it), I then fitted it into an external HDD caddy and (in diskpart) cleaned the disk, created new partition and volume and tried to format it to NTFS. It couldn't do this on long or short formats and so I went with the less-appreciated alternative - exFAT (I run Win7). It quick formats to exFAT fine but encounters errors during long format. At the moment it is exFAT. Of course I would really like it to be NTFS as I will probably need to use it on Win XP too. Could anyone suggest a method of trying to reformat to NTFS? Do you think that, when chkdsk was interrupted first time, the disk was corrupted and is irretrievable? I find this situation slightly odd, as it HAS formatted to exFAT and DOES seem to work when I copy files across! Also, I CAN use disk management console to create several partitions: e.g. a 50GB partition and then a large 180GB partition. The 50GB and WILL long-format to NTFS but the 180GB will not! I'm thinking hardware fault, but then I notice that it WILL format to exfAT! Much confusion!

• Suggestions for accessing SQL Server from internet

  - by Ian Boyd

  i need to be able to access a customer's SQL Server, and ideally their entire LAN, remotely. They have a firewall/router, but the guy responsible for it is unwilling to open ports for SQL Server, and is unable to support PPTP forwarding. The admin did open VNC, on a non-stanrdard port, but since they have a dynamic IP it is difficult to find them all the time. In the past i have created a VPN connection that connects back to our network. But that didn't work so well, since when i need access i have to ask the computer-phobic users to double-click the icon and press Connect i did try creating a scheduled task that attempts to keep the VPN connection back to our office up at all times by running: >rasdial "vpn to me" But after a few months the VPN connection went insane, and thought it was both, and neither, connected an disconnected; and the vpn connection wouldn't work again until the server was rebooted. Can anyone think of a way where i can access the customer's LAN that doesn't involve opening ports on the router needing to know their external IP customer interaction of any kind Blah blah blah use vpn vnc protocol has known weaknesses you are unwise to lower your defenses it's not wise to expose SQL Server directly to the internet you stole that line from Empire Customer doesn't care about any of that. Customer wants things to work.

• ASP.NET sending email through exchange problem

  - by Solmead

  I have an exchange 2010 server running on Windows 2008 R2, I also have a remote webserver running Windows 2003 with multiple sites on it (all asp.net mvc 2 sites). I setup a Transport in exchange and all the websites on my remote web server can send email no problem to anyone in the exchange server and to any external domain. Now for my problem. I am having issues with that webserver, so I moved one of the websites to run on my exchange server, it runs well (low hit website) except that email doesn't work from that site. I tried changing the Transport in exchange to add the IP address of the local machine and the 127.0.0.1 addresses and it still isn't sending any email. Any ideas on how to get this working? The remote websites can still send email no problem, the version of the site that I had to move on the remote server can still email, but on the exchange server for that website email does not send. I would guess it is a Transport issue, since it is running on the same server a firewall shouldn't be the issue. I changed the smtp setting in web.config to localhost, and now I do receive email to my account on the exchange server, but I do not receive any emails on outside addresses. To add more description, this is a custom developed asp.net mvc 2 website. And no errors were being generated in the code when sending the email in either case.

• Photoshop CS6 Corrupted File recovery

  - by Ben Franchuk

  Last night I was working on a client application mock-up in photoshop, but was goin to take a break from my work so I saved the .PSD file on my internal HDD and put my computer into stand-by mode once the file had finished saving. Unfortunately my computer crashed while it was entering stand-by and shut itself down (photoshop was still open). I did not boot it again to make sure all my files were ok because they had already been saved, but today once I opened up the file again it was extremely corrupted and also completely un-editable (screenshot bellow). so what im asking is there any way to recover my work, or at least some of it? i have put in a good few days work on this project and would hate to have to restart it. the size of the file is 3070 KB, even though it reads as 712 KB in photoshop. i dont know if these file sizes are larger or either smaller than the original non-corrupted file's size, but considering all the layers in the file i suspect it was larger before it corrupted. im using windows XP professional 32bit SP3. both my OS and said .PSD file are located on the same internal HDD (74.4 GB). i do have an external HDD (1.5 TB) but i primarily only use it for movies music and tv shows. i dont know if it was plugged in t the time of me editing the document last, though, if it means anything. i have tried many image and PSd recovery softwares but none have returned any results that may help recover my work. edit: i tried using a photo reccovery software (odboso Photorecovery) that actually seems to recover the corrupted file in question judging by the size of the file, but i cannot recover it because of the licence fee. knowing that the file is still likely on my HDD, what location might it be located?

• RRAS Public Address Pool on Windows Server 2008

  - by Art

  I have a Windows 2008 server with two NICs running RRAS and a small public website. It also does NAT for several other PCs on my network and everything works great. I have a block of 5 public static IPs from my ISP, one of which is bound to the public NIC in the Windows 2008 server. I would like to assign one of the remainging 4 public IPs to a machine on my private network. I thought I could do this by going into RRAS, selecting NAT under IPv4 and then adding the public IP address to the address pool and specifying a reservation for the machine I would like to use that address by adding its private ip address. When I do this, the machine I reserved the public IP address for seems to loose all outside network connectivity. I can still ping other PCs on my 192.168.0.* net, but anything outside is no longer reachable. When I remove the reservation, everything seems to work. After setting the reservation and right clicking on the external public interface and selecting 'Show Mappings' I can see outbound requests from my private address with the desired associated private address, however I do not see any inbound requests. What am I doing wrong/missing?
