• Certificates in SQL Server 2008

  - by Brandi

  I need to implement SSL for transmissions between my application and Sql Server 2008. I am using Windows 7, Sql Server 2008, Sql Server Management Studio, and my application is written in c#. I was trying to follow the MSDN page on creating certificates and this under 'Encrpyt for a specific client', but I got hopelessly confused. I need some baby steps to get further down the road to implementing encryption successfully. First, I don't understand MMC. I see a lot of certificates in there... are these certificates that I should be using for my own encryption or are these being used for things that already exist? Another thing, I assume all these certificates are files are located on my local computer, so why is there a folder called 'Personal'? Second, to avoid the above issue, I did a little experiment with a self-signed assembly. As shown in the MSDN link above, I used SQL executed in SSMS to create a self-signed certificate. Then I used the following connection string to connect: Data Source=myServer;Initial Catalog=myDatabase;User ID=myUser;Password=myPassword;Encrypt=True;TrustServerCertificate=True It connected, worked. Then I deleted the certificate I'd just created and it still worked. Obviously it was never doing anything, but why not? How would I tell if it's actually "working"? I think I may be missing an intermediate step of (somehow?) getting the file off of SSMS and onto the client? I don't know what I'm doing in the least bit, so any help, advice, comments, references you can give me are much appreciated. Thank you in advance. :)

• Nginx: Loopback connection via PHP's getimage size crashes server (Magento's CMS)

  - by Alex

  We were able to trace down a problem that is crashing our NGINX server running Magento until the following point: Background info: Magento Backend has a CMS function with a WYSIWYG editor. This editor loads some pictures via a controller in magento (cms/directive). When we set the NGINX error_log level to info, we get the following lines (line break inserted for better readability): 2012/10/22 18:05:40 [info] 14105#0: *1 client closed prematurely connection, so upstream connection is closed too while sending request to upstream, client: XXXXXXXXX, server: test.local, request: "GET index.php/admin/cms_wysiwyg/directive/___directive/BASEENCODEDIMAGEURL,,/ HTTP/1.1", upstream: "fastcgi://127.0.0.1:9024", host: "test.local" When checking the code in the debugger, the following call does never return (in ´Varien_Image_Adapter_Abstract::getMimeType()` # $this->_fileName is http://test.local/skin/adminhtml/base/default/images/demo-image-not-existing.gif` # $_SERVER['REQUEST_URI'] = http://test.local/admin/cms_wysiwyg/directive/___directive/BASEENCODEDIMAGEURL list($this->_imageSrcWidth, $this->_imageSrcHeight, $this->_fileType, ) = getimagesize($this->_fileName); The filename requests is an URL to the same server which is requesting the script a link to a static .gif that is not existing. Sample URL: http://test.local/skin/adminhtml/base/default/images/demo-image-not-existing.gif When the above line executed, any subsequent request to the NGNIX server does not respond any more. After waiting for around 10 minutes, the NGINX server starts answering requests again. I tried to reproduce the error with a simple test script that only calls getimagesize() with the given URL - but this not crash. It simple leads to an exception saying that the URL could not be loaded (which is fine as the URL is wrong)

• Ubuntu Server, 2 Ethernet Devices, Same Gateway - Want to force internet traffic through 1 device (or at least allow it to work!)

  - by Chris Drumgoole

  I have a Ubuntu 10.04 Server with 2 ethernet devices, eth0 and eth1. eth0 has a static IP of 192.168.1.210 eth1 has a static IP if 192.168.1.211 The DHCP server (which also serves as the internet gateway) sits at 192.168.1.1. The issue I have right now is when I have both plugged in, I can connect to both IPs over SSH internally, but I can't connect to the internet from the server. If I unplug one of the devices (e.g. eth1), then it works, no problem. (Also, I get the same result when I run sudo ifconfig eth1 down). Question, how can I configure it so that I can have both devices eth0 and eth1 play nice on the same network, but allow internet access as well? (I am open to either enforcing all inet traffic going through a single device, or through both, I'm flexible). From my google searching, it seems I could have a unique (or not popular) problem, so haven't been able to find a solution. Is this something that people generally don't do? The reason I want to make use of both ethernet devices is because I want to run different local traffic services on on both to split the load, so to speak... Thanks in advance.

• How do I setup a proper VPN for my friends to play LAN games AND give them internet access?

  - by Gizmo

  I'm trying to setup a VPN on my local network, but everyone who connects to me DOES have access to my laptop but not to the internet or other devices on the network. How can I properly configure my VPN on windows to work correctly (giving internet + access to all devices on my network to the remote pc)? Or is there software on windows which makes creating a VPN server easier? or maybe a VMWare image linux vpn server? I can't find any of those! My requirement is that my friends don't have to install additional software, they have to be able to connect with default windows stuff. My OS is Windows 8 Standart edition (not pro or enterprise) OEM. Most of my friends have also windows 8, some windows 7. Extra info: My device is DMZ'ed (Demilitarized Zone, [disabled NAT on my device so it's accessible on the WAN]) I can access files, websites and services on other devices on my network, and all devices can access file shares, website and all other services on my device When enabling VPN everything works except the client is unable to get internet access or access to any device on my network, client has only access to my device.

• Google Apps Domain Level Shared Contacts?

  - by dkirk

  My firm just switched to Google Apps Premiere addition 2 weeks ago and aside from the way Google handles shared contacts, things are going quite well. Previously, on our Exchange server we had numerous shared contact lists set up in the shared folders. We had a separate list for vendors, sales agents, etc.. Is there not a way to set up lists or groups such as this on the domain level in Google Apps? I have found a ton of forums with users asking the same question but no good answers unless you purchase some third party app in the marketplace. I have toyed around with the "google-shared-contacts-client" here: http://code.google.com/p/google-shared-contacts-client/ and this almost does it but it falls short when trying to group contacts on the domain level or when trying to search for a contact by company name. Are either of these things possible? I am now looking to create a Google Doc spreadsheet to share with the domain just to have a separated defined list of contacts that is search-able by various fields... Anyone who could shed some light on domain level contact sharing relating to the points above, I would be most grateful...

• Euro character messed up during FTP transfer

  - by djechelon

  My customer is using a very outdated ecommerce management system on my hosting service. For that product, no support is being provided anymore by the vendor. Brief explanation: the shop website, that claims to run under LAMP stack, is built by an old Visual Basic Windows application running on MS Access. The user constructs the shop, defines the HTML template, adds products and categories, etc. Then the VB exe builds the PHP pages (one for each template page) and the SQL script to run on MySQL. It also uploads everything via FTP and runs the installation/upgrade script on its own. The problem Browsing the website, many products' descriptions are cut before the euro sign. For example, what was supposed to be "Product price €1000" becomes "Product price" The analysis MySQL contains a cutted description until the € sign, so it's not PHP fault The Access databases contain full description with € sign, so it's not fault of the webmaster writing bad description or eDisplay cutting them The SQL that will run once the site gets uploaded, stored on my local machine before upload, contains the € sign The same script, after being FTPed by eDisplay and opened with nano from SSH, shows the € sign messed up like this: ^À vsftpd log reports (obfuscated for privacy) Sat Dec 15 11:16:57 2012 22 xxx.xxx.128.13 1112727 /srv/www/domains/xxxxxx.it/htdocs/db.sql b _ i r xxxxxxx ftp 0 * c which seems to be a binary transfer (and also a huge security vulnerability because you can download the whole database from unauthenticated HTTP) The eDisplay internal FTP client provides no option for ascii/binary transfer modes [Add] Trying to manually upload the SQL file via SFTP shows messing up euro [Add2] Trying to manually upload using Xftp client with explicit ASCII mode doesn't fix too It looks like the file gets uploaded as binary. Perhaps on the customer's previous host it all worked fine because that was a Windows host. The server It's an Azure virtual machine running openSUSE 12.2 with both vsftpd and openSSH The question Without asking the customer to manually upload files using FileZilla or replacing € with &euro;, because he refuses, what can I do on server side to prevent vsftpd to screw up euro sign?

• LAN Webserver not accessible through PPTP VPN

  - by Joe

  I have this LAN Network with 10 clients and one server. The server has 4 virtual machines and a BIND DNS Server. When the router assigns an IP through the DHCP , it also gives the ip of the DNS Server, to resolve internal domains. Everything apparently works fine, the clients being able to access the server's vm's resources, but I also have to create the possibility of remote access. I installed the PPTP VPN on the server, and the vpn clients would get the same ip address range as the router's dhcp is assigning. Apparently everything is fine here also, except the fact that when we connect through the vpn , we cannot access the webserver on port 80 ( the webserver being one of the server's VM ). The iptables on the webserver has been turned off for testing purposes and the router's firewall is directing all the external traffic to the server. Can somebody suggest a solution to this? Extra details : VPN Server : PPTP Server Centos 6.3 x64 VPN Client : Windows 7 default PPTP VPN Connection The client is successfully connected to the server, everything works ( FTP/MYSQL/SSH/DNS ) , except the fact that when I try to access the webserver IP on the browser, it won't work.Pinging it works perfectly.

• How to use iptables to forward all data from an IP to a Virtual Machine

  - by jro

  OK, in an attempt to get some response, a TL;DR version. I know that the following command: iptables -A PREROUTING -t nat -i eth0 --dport 80 --source 1.1.1.1 -j REDIRECT --to-port 8080 ... will redirect all traffic from port 80 to port 8080. The problem is that I have to do this for every port that is to be redirected. To be future-proof, I want all ports for an IP to be redirected to a different (internal) IP, so that if one might decide to enable SSH, they can directly connect without worrying about iptables. What is needed to reliable forward all traffic from an external IP, to an internal IP, and vice versa? Extended version I've scoured the internet for this, but I never got a solid answer. What I have is one physical server (HOST), with several virtual machines (VM) that need traffic redirected to them. Just getting it to work with a single machine is enough for now. The VM's run under VirtualBox, and are set to use a host-only adapter (vboxnet0). Everything seems to work, but it is greatly lagging. Both the host (CentOS 5.6) and the guest (Ubuntu 10.04) machine are running Linux. What I did was the following: Configure the VM to have a static IP in the network of the vboxnet0 adapter. Add an IP alias to the host, registering to the dedicated (outside) IP. Setup iptables to allow traffic to come through (via sysctl). Configure iptables to DNAT and SNAT data from a given IP address to the internal address. iptables commands: sudo iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT sudo iptables -A POSTROUTING -t nat -j MASQUERADE iptables -t nat -I PREROUTING -d $OUT_IP -I eth0 -j DNAT --to-destination $IN_IP iptables -t nat -I POSTROUTING -s $IN_IP -o eth0 -j SNAT --to-source $OUT_IP Now the site works, but is really, really slow. I'm hoping I missed something simple, but I'm out of ideas for now. Some background info: before this, the site was working with basic port forwarding. E.g. port 80 was mapped to port 8080 using iptables. In VirtualBox (having the network adapter configured as NAT), a port forwarding the other way around made things work beautifully. The problem was twofold: first, multiple ports needed to be forwarded (for admin interfaces, https, ssh, etc). Second, it only allowed one IP address to use port 80. To resolve things, multiple external IP addresses are used for different (sub)domains. Likewise, the "VirtualBox" network will contain the virtual machines: DNS Ext. IP Adapter VM "VirtalBox" IP ------------------------------------------------------------------ a.example.com 1.1.1.1 eth0:1 vm_guest_1 192.168.56.1 b.example.com 2.2.2.2 eth0:2 vm_guest_2 192.168.56.2 c.example.com 3.3.3.3 eth0:3 vm_guest_3 192.168.56.3 And so on. Put simply, the goal is to channel all traffic from a.example.com to vm_guest_1 (of put differently, from 1.1.1.1 to 192.168.56.1). And achieve this with an acceptable speed :).

• What is the typical maximum number of database connections for Oracle running on Windows server ?

  - by Sake

  We are maintaining a database server that serve a large number of clients. Each client typically running serveral client-applications. The total number of connections to the database server (Oracle 9i) is reaching 800 connections on peak load. The windows 2003 server is starting to run out of memory. We are now planning to move to 64bit Windows in order to gain higher memory capability. As a developer I suggest moving to multi-tier architecture with conneciton pooling, which I believe is a natural solution to this problem. However, in order to support my idea, I want the information on: what exactly is the typical number of connections allowed for Oracle database ? What is the problem when the number connections is too high ? Too much memory comsumption ? or too many sockets opened ? or too many context switching between threads ? To be a little bit specific, how could Oracle Forms application scale to thousand of users without facing this problem ? Shall Oracle RAC applied to this case ? I'm sure the answer to this question should depend on quite a number of factors, like the exact spec of the hardware being used. I'm expecting a rough estimation or some experience from the real world.

• RDP suggesting a user name when connecting to a server

  - by Neolisk

  Prior to Event X, RDPing to Server 2003 always caused the user name appear blank and Login to be enabled, so you could pick to which domain you would log in. For us it's either local or our domain. Since a recent Event X a domain + user name is being suggested for every server and it's not the most recently used user name. If you remove it manually from RDP dialog, it's still being pre-populated for you, and then at the next available opportunity it returns into General/User name option of RDP dialog. So user name field comes pre-populated and you cannot change to log in locally (only if you manually erase domain specifier - everything before \) - Log in to option is disabled by default. We did not do any changes to our domain or client machines, so I am suspecting some Windows update caused it (and this being Event X). Interesting fact - it does not consistently happen on all machines, and some can login to some servers fine, while other servers keep suggesting a default user name. What could be that Event X and is there a way to fix it? EDIT: I tried this - How to clear remote desktop connections history and specifically this part of it: reg delete "HKEY_CURRENT_USER\Software\Microsoft\Terminal Server Client\UsernameHint" /f The problem still persists.

• How to track things that SHOULD happen, but might not have

  - by Kamiel Wanrooij

  I am running into a couple of issues with some applications we've deployed and maintain. I have the feeling we have approached this with some anti-patterns up to now, but I would like to see how to make this more flexible and stable. In one situation, we have a server at a client which pushes data to us to parse every night (yes, Windows Task Scheduler). This is highly unstable however, so once every month this doesn't happen because of reasons out of our control. This heavily impacts our business since we run with stale data in that situation. In another scenario we have a lot of background job processes that should be running. We already keep them up using bluepill ( http://www.github.com/arya/bluepill ) but obviously restarts happen, both automatically and manually, and people forget things or systems mess up. What I would like to track is events that should occur or should be available. Like the existence of a process, the execution of a program, or the creation/age of a file, and track it when they don't happen or exist. We develop most things in Ruby on Rails, use NewRelic, Bluepill and Munin, and run on Ubuntu. I've been toying around with counting ps aux | grep processname | wc -l in Munin scripts, or capturing the age of a file and raising alerts over 24-26 hours, stuff like that. Is there better tooling to track things that should happen, and raise alerts if they don't? P.S. I know some things are suboptimal, like manually having to define bluepill for applications and then forgetting to do so. The same goes for the push based approach of the first application, a dedicated daemon that manages that on the client side that we control and can track its connection to us might be a much better solution.

• Internet compression proxy for low speed broadband?

  - by user23150

  I live in a rural location, using high-latency wireless off a local ISP's tower. My speed tests vary day to day, but I can get around 1Mb up/down. The problem is, I work with large files, uploading and downloading (HD videos, development software, etc.). It can be painful to wait sometimes. Plus I do some side contract game development, and it can be very difficult to playtest with other developers (200ms ping is a good day for me). Now, obviously it's not going to be easy to solve the latency problem without different wireless hardware. But speedwise, I am wondering if I can use some kind of compression technology on a proxy. For instance, my work computer has full access to a 26Mb down, 10Mb up connection, that is totally unused at night and the weekends. If I could run some kind of compression technology on our server, and use it as a proxy to route to my home computer, I could stand to gain some major speed. I realize that by bogging down a system with compression, I could potentially lose whatever speed gain I had. But the proxy server is a quad core xeon, and the receiving computer is a pretty decent i7 computer, so that shouldn't be a concern. I found http://toonel.net/ but it seems more geared toward very slow narrowband users, like dial-up. Plus, I would prefer to just be able to point my browser to a proxy server, rather then install software on my client machine. EDIT I thought about my question a little more, and realize I am going to need to install software on my client in order to decompress, and possible compress (for uploading). That's not a huge deal.

• Group Policy - Published software not upgrading

  - by VokinLoksar

  I'm testing this with mercurial MSIs, but it's the same for other packages. I've created a new group policy and added an old version of mercurial to User software installation as a Published package. On a Windows 7 client I install the package through Programs and Features. The installation works fine. Now, I would like to publish an updated version of mercurial. I create a new Published package. Under 'Upgrades' I configure it to replace (upgrade also doesn't work) the old version and mark this upgrade as 'Required'. The old package is not removed. The Windows 7 client is then restarted. When I log back in, I see a status message saying something like 'Removing managed software Mercurial ...'. There is no message about installation of the upgrade. If I look in Programs and Features, I can see the new version of mercurial listed. However, the actual mercurial directory under Program Files is missing. It's as though the installation recorded information about the MSI, but didn't actually install anything after removing the old version. As I mentioned, this isn't specific to mercurial. I've tried using other apps and have yet to find one that can be upgraded via a Published package. Using Assigned packages in Computer Configuration works without problems, but I would like this software to be optional rather than required. Ideas?

• How to get a list of Dovecot IMAP users

  - by Colt McCormack

  How do you get a list of users for a dovecot email server that connect via IMAP (as opposed to POP)? Our server is setup to authenticate via LDAP/PAM. Is there an easy way to get a list of the users who are accessing their mail via IMAP, rather than POP? I am about to migrate our server to Google Apps and want to migrate all of the mail for my IMAP users only (couple hundred out of several hundred total users). POP mail will be migrated separately from the client end obviously. I would much rather migrate only the IMAP users rather than the whole domain which would include migrating a bunch of POP mail left in the server that has already been read/sorted/deleted in the client's email program. Migrating all of that extra useless leftover POP mail could waste weeks of migration time. I suppose parsing some logs to see who has connected on an IMAP port (995 or 993) would give me a list would work if someone could help me do that. I know I have the raw dovecot logs, but am hoping for a cleaner solution.

• Strange Domain name under the same IP Address

  - by Mike Chip

  There's something really weird happening in my server. But first things first: I wanted to have my website and chose the domain name "myowndomain.com", Now on my domain registrar I point "myowndomain.com" to the address of my recently setup VPS, let's say 50.50.50.50 So I installed everything I needed to run my website, and I started to notice strange queries coming from different IP Addresses. Like these [client 123.123.123.123] File does not exist: /var/www/html/api, referer: http://www.strangedomain.com/api/manyou/my.php [client 456.456.456.456] File does not exist: /var/www/html/api, referer: http://www.strangedomain.com/api/manyou/my.php or like this (Really a long line, I cut some things) GET /?s=vod-show-id-22-area-%E5%85%B6%E4%BB%96-language-%E9%9F%A9%E8%AF%AD.html HTTP/1.1" 301 295 "http://v.strangedomain.com/?s=vod-s ...[cut]... spider" That above is happening the most. The 'strangedomain.com' returns the same IP address of my VPS which my website is hosted on. The whois of such domain shows it's registered to a chinese. But the street name didn't look so right (like a huge single word), so I think all of that info might be fake, but still might be a chinese. I also noticed that all 'clients' trying to access the 'strangedomain.com' is coming from china. If I type in the browser 'strangedomain.com', I see my website. I'm worried, because my website is actually an e-commerce. I don't know if 'strangedomain.com' WAS a website on 50.50.50.50 in the not so far past, or if it's something else.

• How many bootable partitions are possible to have on one hard drive?

  - by draiden

  This may not be the correct place to post this; if that's the case, just let me know and point me in the right direction please! I'm thinking of building a box that needs to be lightweight and portable, and would need to be able to boot multiple installations of windows. I am needing to have multiple installations so that I can, for example, plug the box in to the network at one location, boot in to that location's partition, and have full access to everything I would normally need to do on a computer that has already been set up on that network. Then, when I go to the next client, I would be able to do the same thing, with the new location's partition, and have all of those network settings, drive mappings, etc., available there. Obviously I'd need to go through and set them all up on the different locations/networks, I'm not expecting it to magically know where I am and what I'm doing. It would be like I'm carrying around a computer that is configured for each place I need to go in one little box, instead of having to have multiple computers or having to reconfigure all the settings and such every time I go to another client. Or is there an easier way to do this that I haven't learned of?

• Cannot connect to my VPN Server from another network

  - by SantaC

  ok here is the deal. I have a Windows 2008 R2 server with RRAS installed configured for VPN. I also have DHCP running. On my DC I have AD running and they're connected with my domain. I am only using one NIC though. As a client I have Windows 7. So I tried connecting to my VPN server through my own network, which worked fine, so the setup is correct. However, when I tried connecting to my VPN server on another network, it does not work. I went to my brothers home and tried connecting to my server but it did not pass. So on my VPN server I have ip: 192.168.2.99 At my brothers house, i did the configuration on his windows 7 and it cannot connect to that ip. I am operating on the 192.168.2.1 network and he is operating on the 192.168.0.1 network. So how do I configure his client in order to get it to work? I tried changing his ip to the 192.168.2.x network, but i am not sure you can do that. I need some help here what to do.

• Static DHCP binding

  - by Alex

  Good time of day, SF people. I have created a manual DHCP binding entry on a Cisco router so that a client would always get leased to it. The clients wants to get the same address on both of his dual-boot linux systems. He tries to get an IP address leased and he succeeds on one of the dual-boot operating systems. When he reboots to another one he gets a lease for a completely different one. I don't get it. The MAC addresses are the same (we checked in ifconfig, so what could be happening here? Why is the router confused? Or is it something else? Also, how can I check DHCP server IP address who I have got an IP address from (on Linux)? Configuration on Cisco: ip dhcp pool MANUAL_BINDING0001 host 192.168.0.64 255.255.255.0 hardware-address dead.beef.1337 dns-server 192.168.8.11 default-router 192.168.0.254 domain-name verynicedomainigothere.cn PS. Is it mandatory to use client-name configuration line?

• Enabling `mod_rewrite` apache, permissions issues

  - by rudolph9

  In attempting to enable mod_rewrite on the Apache2 web server installed with Mac OSX 10.7.4. Following these instruction, ultimately using the configuration to host CakePHP applications, I run into permissions issues accessing the site via a web browser when I set the directory block associated with cakephp site /etc/apache2/users/username.conf from: <Directory "/Users/username/Sites/"> Options Indexes FollowSymLinks MultiViews AllowOverride none Order allow,deny Allow from all </Directory> /etc/apache2/users/username.conf to: <Directory "/Users/username/Sites/"> Options Indexes MultiViews AllowOverride none Order allow,deny Allow from all </Directory> <Directory "/Users/username/Sites/cakephp_app/"> Options Indexes FollowSymLinks MultiViews AllowOverride all Order allow,deny Allow from all </Directory> The .htaccess files are the CakePHP 2.2.2 default as follows: /Users/username/Sites/cakephp_app/.htaccess <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ app/webroot/ [L] RewriteRule (.*) app/webroot/$1 [L] </IfModule> /Users/username/Sites/cakephp_app/app/.htaccess <IfModule mod_rewrite.c> RewriteEngine on RewriteRule ^$ webroot/ [L] RewriteRule (.*) webroot/$1 [L] </IfModule> /Users/username/Sites/cakephp_app/app/webroot/.htaccess <IfModule mod_rewrite.c> RewriteEngine on RewriteCond %{REQUEST_FILENAME} !-d RewriteCond %{REQUEST_FILENAME} !-f RewriteRule ^(.*)$ index.php [QSA,L] </IfModule> When performing the request via a web browser at to http://0.0.0.0/~username/cakephp_app/index.php the content of the response is Not Found The requested URL /Users/username/Sites/cakephp_app/app/webroot/ was not found on this server.

• Asterisk relay between multiple subnets

  - by immoune

  I wonder what's the best way to go when you have phones on multiple networks which are not directly reachable. I have 3 networks 10.3.x.x 10.6.x.x 10.17.x.x My asterisk server resides on the 10.3.0.5 IP. The machines from the 10.6 and 10.17 networks are routed here through VPN tunnels. At this point we don't talk about NAT anywhere on the network just pure routing. Since the 10.3.0.5 PBX has routes back to all the subnet's it has no problem to communicate with softphones/hardphones from these ranges. The problem comes from that Asterisk (as far as I understand) only responsible for the SIP communication part not the Audio/Video transmission which is in P2P fashion done between the devices. So although a client using sipdroid from 10.6.x.x is able to connect to the pbx (10.3.0.5) and dial a bria client on the 10.17.x.x network once the phone rings out and the call establishes no audio will be transmitted simply because it has no way to directly connect there. For this there are multiple solutions described in this text: http://msdn.microsoft.com/en-us/library/ee480411%28v=winembedded.60%29.aspx What I would prefer is to keep these networks segregated as they are now. What would be the best solution? Is it possible to actually relay through all the audio/video information through the Asterisk server? That would be the best in my case, I using Astlinux there which has a lot of other parts. Thanks

• Win7 loses connection to network shares after resume unless server specified using FQDN

  - by Szonja Zemkó

  My Win7 client has a connection to a Linux server and its shared folders. The problem occurs when the computer wakes up after a sleep and then one of the shared folders is not accessible. I receive the following message: Error code: 80070035, The network path was not found. I have problem with one specific folder only. When I restart the computer this problematic folder is accessible again. When I log off before sleep the folder is accessible after wakeup. If I try to access the folder by using the FQDN of the server or the server IP it is also accessible. As a temporary solution I mapped the folder to a network drive using the FQDN and it's working fine but it's inconvenient since every other folder is accessible on the server. To summarize: \server\problematicshare no longer works after resume (the Samba server sees my client connect, then disconnects a few seconds later while I receive the above error message) \server\othershare works after resume \fqdn.of.server\problematicshare always works \ip.of.server\problematicshare always works once the problem manifests, I'm no longer able to restart the "Workstation" service (it is not responding) restarting the "Computer Browser" service has no apparent effect the event log doesn't contain anything that seems relevant "ping server" works

• Have some questions about setting up a VPN to my private cloud servers

  - by Pure.Krome

  I've got a number of Virtual Servers running at a pretty big Cloud provider. They are all running Windows 2008 R2. I have a CISCO ASA firewall in front of them. Currently, I've got all ports blocked except 80/443/21/3386 (for Remote Desktop). I asked to have a VPN enabled on the firewall and they said it's easy to do BUT I need to use the 3rd party Cisco software. Now, I don't want to get into a debate about it .. but we don't want to install anything extra on our -client- computers. We all use Windows 7 and we love using the built in VPN client to connect to other private LANS we have setup in other locations. So i'm wondering what options I have to create a VPN tunnel to our private cloud LAN? All our cloud servers are part of WORKGROUP, so there's no Active Directory .. nor do we want to install all that. Secondly, we know we can open up a firewall port - so any ports for starting a VPN is fine! Lastly, I was thinking of just using one of the existing servers as the VPN server (and using the Windows VPN software) .. but I'm not sure this is a good thing? Remember - we just want to use the baked in VPN software in Windows 7 .. which is PPTP or SSTP or L2TP/IPSEC. I would -LOVE- to use some free OSS software. For usernames/passwords? We'd probably just have one account .. like U:Hithere P:whatever.. so we don't need any hardcore account management, like Active Directory, etc. So does anyone have any ideas?
