• RD Gateway reporting features/capabilities

  - by Don

  We have just implemented RD Gateway for our own department in preparation for a push to the whole agency for telecommuting. It is all setup and working great, but I was trying to figure out how best to go about monitoring/reporting of users. I see third party software out there that will do it, but is there anything built-in or via powershell/scripting that I could use that would give me a report of the daily activity of users? Something to say, "User A connected at this time, was on for this long, sent/received this much data"? Basically some of the same stuff you can see in event viewer. Ideally I'd like to be able to have this setup so that once a day it emails me with the daily usage for when a supervisor asks about if their person is actually working (or at least online sending and receiving x amount of data), I'll have some metrics to give them. I realize that actual work output is relevant and more of a managerial issue, but I would like to be able to offer as much as I can from my end when asked. Thoughts? Thanks!

• Router reporting failed admin login attempts from home server

  - by jeffora

  I recently noticed in the logs of my home router that it relatively regularly lists the following entry: [admin login failure] from source 192.168.0.160, Monday, June 20,2011 18:13:25 192.168.0.160 is the internal address of my home server, running Windows Home Server 2011. Is there anyway I can find out what specifically is trying to login to the router? Or is there some explanation for this behaviour? (not sure if this belongs here or on superuser...) [Update] I've run both Wireshark and netmon for a while on my home server. Wireshark captured the traffic, but didn't really show anything useful (or nothing I could make use of). A simple HTTP GET request is sent from the server (192.168.0.160) to the router (192.168.0.1), from a seemingly random port (I've seen examples from 50068, 52883), and it appears to do it twice in quick succession (incrementing port by 1), about every hour. Running netstat around the time of the failure didn't show anything (probably too long after anyway). I tried using netmon as it categorises by process, so I thought it might show a corresponding process for the port. Unfortunately, this comes in under the 'unknown' category, meaning it's basically just a slower, less useful Wireshark. I know there's not much to go on here, but does this help in anyway?

• Best Asp.net Hosting

  - by dotnetguts

  There are many asp.net web hosting companies which spends lot on advertisement and also gives you very cheaper rate, as low as $5, but when it comes to support they are simply hopeless. Everyone can you please pass your experience with your past hosting companies and suggest any good asp.net hosting company? Please consider following requirement factors 1) Asp.net 3.5 or 4.0 supported. 2) Url Rewriter support 3) GZip support (Dynamic through code) 4) Initial Setup support (If required) 5) SQL Server 2005 or 2008 6) Allow to access SQL Server DB using SQL Mgmt Studio 7) Environment supporting Backup and Restore of DB on my own, without involving tech support team 8) Full Text Search support 9) FTP support 10) I can able to send atleast 500 Emails daily. 11) 99.9% Up Time (No matter all web hosting say they have 99.9% Up Time, but its not true). 12) Alert Email to be sent when they do any maintenance or during downtime. 13) Hosting Price should be reasonable. Incase you feel i am missing something please add to the list. Can anyone suggest good webhosting company based on above factors?

• Apache returns HTTP 206 for GET /file.mp3

  - by javano

  I am making a get request to an SSL enabled site on apache (so wireshark isn't giving me anything to useful). In my Apache SSL access log I see the following entry: 1.2.3.4 - my.username [15/Nov/2012:16:52:01 +0000] "GET /uploads/file.mp3 HTTP/1.1" 206 534400 "https://site.com/uploads/layla.mp3" "Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/535.19 (KHTML, like Gecko) Ubuntu/12.04 Chromium/18.0.1025.168 Chrome/18.0.1025.168 Safari/535.19" Why is this happening? I'm not familiar with the HTTP 206 response code but searching the Internet I can see it is a partial content GET requests. I understand correctly, my browser is making a partial GET request not for the full file. Is that correct? If so, is this a browser issue or is the web server instructing my browser to do so? I have tested in Firefox also and in both browser, I am not sent the file. If I rename the file to file.jpg I can download it through my browser and rename it to .mp3 and it plays. How can I troubleshoot this issue?

• How to minimize the risk of employees spreading critical information?

  - by Industrial

  Hi everyone, What's common sense when it comes to minimising the risk of employees spreading critical information to rivalling companies? As of today, it's clear that not even the US government and military can be sure that their data stays safely within their doors. Thereby I understand that my question probably instead should be written as "What is common sense to make it harder for employees to spread business critical information?" If anyone would want to spread information, they will find a way. That's the way life work and always has. If we make the scenario a bit more realistic by narrowing our workforce by assuming we only have regular John Does onboard and not Linux-loving sysadmins , what should be good precautions to at least make it harder for the employees to send business-critical information to the competition? As far as I can tell, there's a few obvious solutions that clearly has both pros and cons: Block services such as Dropbox and similar, preventing anyone to send gigabytes of data through the wire. Ensure that only files below a set size can be sent as email (?) Setup VLANs between departments to make it harder for kleptomaniacs and curious people to snoop around. Plug all removable media units - CD/DVD, Floppy drives and USB Make sure that no configurations to hardware can be made (?) Monitor network traffic for non-linear events (how?) What is realistic to do in a real world? How does big companies handle this? Sure, we can take the former employer to court and sue, but by then the damage has already been caused... Thanks a lot

• Building My First Computer And Suprise It Isn't Working

  - by BobbShots

  I've had many years of experience working on and around computers, but this was my first foray into building one completely from scratch. So far that foray has been a disaster. My rig is completely assembled, and on its maiden power-up plus many power cycles I noticed three things: There were a few beeps from the BIOS POST upon powering up the first time, but I wasn't paying attention completely to the sequence. However, every time after that there are 0 POST beeps, even after taking off all hardware except the CPU and MB. There was no video being sent to the monitor. I run a HDMI cable from my video card to the monitor. The video card was LOUD. My card is a Sapphire Radeon HD 5870 which is known for not only being a powerhouse, but being pretty quiet. A few times during my power cycles it ran a lot quieter, but most of the time it was just super loud. Can anyone provide help for any of these issues? My MB, CPU, and Video Card are: MB: ASUS P6X58D Premium LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard CPU: i7 920 Video Card: Sapphire Radeon HD 5870

• How do I set up an email server that automatically maintains a list of previous recipients?

  - by hsivonen

  I want to set up an email server with the following characteristics. What software (besides bogofilter and clamav that I'm naming) should I use and what HOWTOs should I read? The server should run some flavor of Linux that's as low-maintenance as possible and self-updates for security patches in a timely fashion. (Debian stable?) When email is sent, all the recipients are stored in the list of previous recipients maintained by the server. Scan incoming messages with clamav and treat as spam if it contains viruses. When email arrives (if it passed clamav), if the sender is on the list of previous recipients, bypass spam filter. If the List-Id header names a mailing list on a manually maintained list of known-clean mailing lists, bypass spam filter and deliver into a mailbox depending on the mailing list name. Email that wasn't from previous recipients, manually white listed domains or mailing lists gets filtered by bogofilter. Spam goes into a spam mailbox. Email considered to be ham should automatically be fed to bogofilter training as ham. Email considered to be spam (incl. messages with viruses) should be automatically fed to bogofilter training as spam. There should be mailboxes for false ham and false spam that an IMAP client can move email into so that the server retrains bogofilter appropriately. Email sending requires SMTP over SSL. Email reading requires IMAPS. Should I also want to use SpamAssassin in addition to bogofilter?

• jdbc4 CommunicationsException

  - by letronje

  I have a machine running a java app talking to a mysql instance running on the same instance. the app uses jdbc4 drivers from mysql. I keep getting com.mysql.jdbc.exceptions.jdbc4.CommunicationsException at random times. Here is the whole message. Could not open JDBC Connection for transaction; nested exception is com.mysql.jdbc.exceptions.jdbc4.CommunicationsException: The last packet successfully received from the server was25899 milliseconds ago.The last packet sent successfully to the server was 25899 milliseconds ago, which is longer than the server configured value of 'wait_timeout'. You should consider either expiring and/or testing connection validity before use in your application, increasing the server configured values for client timeouts, or using the Connector/J connection property 'autoReconnect=true' to avoid this problem. For mysql, the value of global 'wait_timeout' and 'interactive_timeout' is set to 3600 seconds and 'connect_timeout' is set to 60 secs. the wait timeout value is much higher than the 26 secs(25899 msecs). mentioned in the exception trace. I use dbcp for connection pooling and here is spring bean config for the datasource. <bean id="dataSource" destroy-method="close" class="org.apache.commons.dbcp.BasicDataSource" > <property name="driverClassName" value="com.mysql.jdbc.Driver"/> <property name="url" value="jdbc:mysql://localhost:3306/db"/> <property name="username" value="xxx"/> <property name="password" value="xxx" /> <property name="poolPreparedStatements" value="false" /> <property name="maxActive" value="3" /> <property name="maxIdle" value="3" /> </bean> Any idea why this could be happening? Will using c3p0 solve the problem ?

• Nginx fails upon proxying PUT requests

  - by PartlyCloudy

  Hi. I have an arbitrary web server that supports the full range of HTTP methods, including PUT for uploads. The server runs fine in all tests with different clients. I now wanted to set this server behind an nginx reverse proxy. However, each PUT request fails. The entity body is not forwarded to the backend web server. The header fields are sent, but not body. I searched the nginx proxy documentation and find several hints that PUT might not be supported. But I also found people running svn/ web dav stuff behind nginx, so it should work. Any ideas? Here is my config: server { listen 80; server_name my.domain.name; location / { proxy_set_header X-Forwarded-Host $host; proxy_set_header X-Forwarded-Server $host; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_pass http://127.0.0.1:8000; } } Client == HTTP PUT ==> Nginx == HTTP Proxy ==> Backend Server The error.log shows no entries concerning this behaviour. Thanks in advance!

• Not able to access Silverlight.net and ONLY Silverlight.net - All other domains work!

  - by Sootah

  Alrighty folks, I have an extremely odd problem. I am able to surf the web fine with one odd (and really annoying at the moment) exception: Microsoft's Silverlight.net. Every other site that I go to works just fine. This is quite frustrating because I'm in the middle of programming a web app in Silverlight 4.0, and whenever I do a search for any code examples, tutorials, or whatnot at least 50% of the results are hosted in the silverlight.net forums. The error message that I get is: Oops! Google Chrome could not find www.silverlight.net It doesn't work in my other browsers either (both IE and FireFox). What's odd, is that while the error message would lead me to assume it's a DNS error, I can ping the URL just fine. C:\Users\The Doot>ping silverlight.net Reply from 206.72.125.201: bytes=32 time=106ms TTL=106 Reply from 206.72.125.201: bytes=32 time=106ms TTL=106 Reply from 206.72.125.201: bytes=32 time=106ms TTL=106 Reply from 206.72.125.201: bytes=32 time=106ms TTL=106 Ping statistics for 206.72.125.201: Packets: Sent = 4, Received = 4, Lost = 0 (0% loss), Approximate round trip times in milli-seconds: Minimum = 103ms, Maximum = 110ms, Average = 106ms I've checked my HOSTS file, and there's nothing that refers to ANY Microsoft URL in there. What could be causing this!?? More importantly, how do I fix it? Just for kicks, I've even included the results of a traceroute here for your enjoyment.

• Routing and authenticating all access through squid

  - by Knight Samar

  Hi, I want to route all Internet access in my network through a Squid proxy server and authenticate and log all users. I want this to be a client-independent setting so that no one needs to do anything on their browsers or machines. I have set my network gateway as the proxy server so that all traffic will be sent to it. I have done this using options in DHCP server. Now I tried using squid as a transparent proxy, but then it won't authenticate in that mode. I tried using iptables to route all traffic to port 3128 but it won't popup the authentication dialog box from SQUID. I tried telling DHCP to give WPAD to all clients by placing a WPAD file on a webserver containing the following for automatic proxy configuration on clients: Changes in dhcpd.conf option wpad code 252 =test; option wpad "\n\000"; option wpad "http://192.168.1.5/wpad.dat\n"; The WPAD file: function FindProxyForURL(url,host) { return "PROXY squid-server-ip-address:3128 ; DIRECT "; } But the browsers (different versions of Firefox and IE) seem to ignore it. :( What should I do ?

• Replacement for public folder workflow, I'm confused as to how sharepoint does it.

  - by RodH257

  For years Microsoft has been slowly phasing out public folders, perhaps exchange 2010 really is the LAST TIME they'll be shipped... I've heard sharepoint is the replacement, but I don't understand full, can someone give me an idea of how to replace this workflow? In our office, we have projects, they have a project number, ie 10353. Each job folder has a public folder, organized in a hierachy like Projects Year Folder Subfolders The main subfolder we use is for genera correspondence. When an email is received that relates to a project, it is dragged and dropped (or right click move to) a public folder. Adding public folder favourites for each user helps this. When an email is sent, we have a custom email form, which is the default email form, but with a project number field next to the subject line. When you enter the job number in there, it carbon copies our filing system in, which reads the job number and puts the email in the public folder for you. if you need to refer to emails, you go to public folder and find them there. This isn't the best with large jobs, but it works ok. Now, I have limited experience with sharepoint (well, WSS), we've used it to do some neat discussion boards/polls etc as an intranet site, but I haven't seen much of its integration with outlook. The great thing about our solution is how tightly it integrates with outlook which is exactly where the emails are. If you want to forward an old email, you go to public folder and forward it, simple. Any solution that replaces it should be at least as easy as this. Improvements we would like would be to have better searching of emails, better support in exchange (ie future version) and also, custom forms in outlook are being phased out (the VBA kind), so avoiding these would be good. Does sharepoint do this? or what solutions do this kind of thing?

• How can visiting a webpage infect your computer?

  - by Cybis

  My mother's computer recently became infected with some sort of rootkit. It began when she received an email from a close friend asking her to check out some sort of webpage. I never saw it, but my mother said it was just a blog of some sort, nothing interesting. A few days later, my mother signed in on the PayPal homepage. PayPal gave some sort of security notice which stated that to prevent fraud, they needed some additional personal information. Among some of the more normal information (name, address, etc.), they asked for her SSN and bank PIN! She refused to submit that information and complained to PayPal that they shouldn't ask for it. PayPal said they would never ask for such information and that it wasn't their webpage. There was no such "security notice" when she logged in from a different computer, only from hers. It wasn't a phishing attempt or redirection of some sort, IE clearly showed an SSL connection to https://www.paypal.com/ She remembered that strange email and asked her friend about it - the friend never sent it! Obviously, something on her computer was intercepting the PayPal homepage and that email was the only other strange thing to happen recently. She entrusted me to fix everything. I nuked the computer from orbit since it was the only way to be sure (i.e., reformatted her hard drive and did a clean install). That seemed to work fine. But that got me wondering... my mother didn't download and run anything. There were no weird ActiveX controls running (she's not computer illiterate and knows not to install them), and she only uses webmail (i.e., no Outlook vulnerability). When I think webpages, I think content presentation - JavaScript, HTML, and maybe some Flash. How could that possibly install and execute arbitrary software on your computer? It seems kinda weird/stupid that such vulnerabilities exist.

• How can I automatically synchronize a directory tree on multiple machines?

  - by Blacklight Shining

  I have two Mac laptops and a Debian server, each with a directory that I would like to keep in sync between the three. The solution should meet the following criteria (in rough order of importance): It must not use any third-party service (e.g. Dropbox, SugarSync, Google whatever). This does not include installing additional software (as long as it's free). It must not require me to use specific directories or change my way of storing things. (Dropbox does this IIRC) It must work in all directions (changes made on /any/ machine should be pushed to the others) All data sent must be encrypted (I have ssh keypairs set up already) It must work even when not all machines are available (changes should be pushed to a machine when it comes back online) It must work even when the /directories/ on some machines are not available (they may be stored on disk images which will not always be mounted) This can be solved for Macs by using launchd to automatically launch and kill (or in some way change the behavior of) whatever daemon is used for syncing when the images are mounted and unmounted. It must be immediate (using an event-based system, not a periodic one like cron) It must be flexible (if more machines are added, I should be able to incorporate them easily) I also have some preferences that I would like to be fulfilled, but do not have to be: It should notify me somehow if there are conflicts or other errors. It should recognize symbolic and hard links and create corresponding ones. It should allow me to create a list of exceptions (subdirectories which will not be synced at all). It should not require me to set up port forwarding or otherwise reconfigure a network. This can be solved by using an ssh tunnel with reverse port forwarding. If you have a solution that meets some, but not all of the criteria, please contribute it in the comments as it might be useful in some way, and it might be possible to meet some of the criteria separately. What I tried, and why it didn't work: rsync and lsyncd do not support bidirectional synchronization csync2 is designed for server clusters and does not appear to work with machines with dynamic IPs DRBD (suggested by amotzg) involves installing a kernel module and does not appear to work on systems running OS X

• nginx redirect what is not coming from load balancing

  - by dawez

  I have nginx on SERVER1 that is acting as load balancing between SERVER1 and SERVER2 in SERVER1 I have the upstreams for the load balancing defined as : upstream de.server.com { # similar upstreams defined also for other languages # SELF SERVER1 server 127.0.0.1:8082 weight=3 max_fails=3 fail_timeout=2; # other SERVER2 server otherserverip:8082 max_fails=3 fail_timeout=2; } The load balancing config on SERVER1 is this one: server { listen 80; server_name ~^(?<LANG>de|es|fr)\.server\.com; location / { proxy_pass http://$LANG.server.com; proxy_set_header Host $host; proxy_set_header X-Real-IP $remote_addr; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; # trying to pass a variable in the header to SERVER2 proxy_set_header Is-From-Load-Balancer 1; } } Then in server 2 I have: server { listen 8082; server_name localhost; root /var/www/server.com/public; # test output values add_header testloadbalancer $http_is_from_load_balancer; add_header testloadbalancer2 not_load_bal; ## other stuff here to process the request } I can see the "testloadbalancer" in the response header is set to 1 when the request is coming from the load balancing, it is not present when from a direct access: SERVER2:8082 . I would like to bounce back to the SERVER1 all the direct requests that are sent to SERVER2, but keep the ones from the load balancing. So this should forbid direct access to SERVER2:8082 and redirect to SERVER1:80 .

• Inbox not updating in Exchange 2010, all users affected

  - by TuxMeister

  I'm battling against this darn issue this morning. We have the following setup: Big Hyper-V machine hosting the servers as VM's VM for CAS: WEB.XXX.local VM for Mailbox: EXC.XXX.local Servers are running Server 2008 R2 with Exchange 2010 SP1 Clients are all running Windows 7 Pro x64 with Outlook 2010 x64 The problem we're having is that nobody is able to see any emails received today (16th of October), but they are able to send externally. When I reply back to the email received externally, I don't get an NDR, yet the user cannot see my email. This is what I found and tried thus far: If we create a subfolder in Outlook 2010 and move any email from the inbox into that folder, changes will be immediately reflected in OWA We've been sending test emails to other users internaly and external email addresses and the sent items folder contains all those tests, synced properly to OWA as well Have tried crating a new profile, new emails are still missing Tried disabling Cache Mode, still no luck Also disabled "Download shared folders", still no luck Tried to setup a brand new Exchange mailbox and configured it on a VM that never had Outlook on it, still the same issue Tried restarting Exchange services on both CAS and Mailbox servers, no luck Tried rebooting both CAS and Mailbox servers, still no luck Performed a Mailbox Discovery on my admin account, emails from today are being found in the Discovery results, so the stuff is there, just not updating the user inboxes Any idea about what this hellish thing can be? I've done everything I can think of and also everything I could find out there. Let me know if you need any more details and thanks for reading this!

I hope I will find some one to help me.

• Fetch new Mails (Also from Subfolders) from another IMAP server as new Mail in Postfix

  - by Tobi

  everyone. I have installed Postfix on a server with Aliases and Domains from a MySQL Database. It is configured to forward some adresses to other Mail Accounts and also delivers some mails in local mailboxes that will be queried over a dovecot imap server. For this example let there be two users: [email protected] what is a user that gets its mail just forwarded to let's say [email protected] [email protected] what is a user that accesses its mail from local IMAP. Now, I want to fetch some Mails from another mailserver and handle them as if they were sent to a user of my Mailserver. Lets say those corelations exist: [email protected] has two external accounts: [email protected] and [email protected] [email protected] has also one external account [email protected] The Problem is the new mails on that other Mailserver is not always in the inbox, it might be in subdirectories: mailinglists/all or mailinglists/it but also in mailinglists/some-other-department which is not interesting and should not be delivered. I already found a programm called fetchmail but I cannot find how to fetch subdirectories or decide which subdirectories are fetched.

• Transfer disk contents *without* cloning tools

  - by Chris Cummins

  Is it possible to "clone" a disk which contains programs by performing a copy of all the disk contents (preserving file attributes) from source to destination disk, and unplugging the source disk and changing the drive letter of the destination disk to match that of the source? Context I have a two disk Windows 8 system with a system drive and a data drive. Recently, the data drive developed a number of bad sectors leading to IO errors. I have been sent a replacement drive so I simply need to clone the contents of this data drive onto the replacement. The drive contents include documents & media, user folders (My Documents and related), and some programs (games etc). Problem The problem is that the bad sectors on the source disk causes most disk cloning tools to fail with read errors. Attempted approaches include: Disk clone from live boot environment with Acronis True Image. Fails due to read errors. Disk clone from live boot environment with Clonezilla. Fails due to read errors. Disk clone using Roadkil's Unstoppable Copier. Fails due to hardware timeouts in the HDD (application hangs indefinitely). A straightforward copy from source to destination disk using FreeFileSync (preserving file attributes and metadata). This succeeds. So at the moment I have a replacement disk which contains all of the data from the original disk. Now all I need to is somehow get Windows to replace all references to the old disk to the new one. Is this possible by simply swapping the assigned drive letters? Any help would be greatly appreciated, thanks!

Drop packets if they reach the end of the chain. iptables -P FORWARD DROP # Drop all packets with a bad state iptables -A INPUT -m state --state INVALID -j DROP # Accept any packets that have something to do with ones we've sent on outbound iptables -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT # Accept any packets coming or going on localhost (this can be very important) iptables -A INPUT -i lo -j ACCEPT # Accept ICMP iptables -A INPUT -p icmp -j ACCEPT # Allow ssh iptables -A INPUT -p tcp --dport 22 -j ACCEPT # Allow httpd iptables -A INPUT -p tcp --dport 80 -j ACCEPT # Allow SSL iptables -A INPUT -p tcp --dport 443 -j ACCEPT # Block all other traffic iptables -A INPUT -j DROP For context, this machine is a Virtual Private Server Web app host. In a previous question, Lee B said that I should "lock down ICMP a bit more." Why not just block it altogether? What would happen if I did that (what bad thing would happen)? If I need to not block ICMP, how could I go about locking it down more?

• 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

• SPF for two different outgoing servers?

  - by Marcus

  I have ran into a problem that I think someone should have a really clever answer for. Today we have our own mailserver that looks like "mail.domain.com" – which we use to send out mail to our customers (with a modified PHPMailer script). Usually around 5000 mails every day. Everything from customer support to invoices goes through there. The from-header is set to "[email protected]". We are now thinking of migrating to Google Apps for internal use (with 70+ users). However, we cannot use Gmails SMTP for sending "bulk" mails (they have a limit of 500 outgoing mails per day) so we really want to keep using our current system for sending automated mail to our customers – and using gmails SMTP for our internal use. So, how do we set up our SPF-records (Sender Policy Framework) for this? We do not want to get stuck in any filters for "spoofing" the sender from either type of account (the ones sent from our own server, and through Gmails). In short: we want to be able to use the same e-mail adress (for sending) on two different SMTP servers (and therefore two different IP-adresses). Anyone with a good knowledge off SPF who knows how to go about? Or if it is even possible? Anything else I should think of when switching to Google Apps?

• Can't access server sound card when vnc'd into ubuntu server

  - by Corey Kennedy

  I've set up my ubunutu 10 server with xfce, nxserver, and now tightvncserver so that I can control it remotely from my Windows 7 laptop. NX is working fine for remote access, but when I run (for example) exaile, no sound will be sent through the server's sound card. I installed tightvncserver and connected, but ran into the same problem. Exaile opens, sound isn't muted, I can see that sound cards are installed (via cat /proc/asound/cards), but I can't seem to get the remote sessions to access the server's sound card. Also, just to confirm that the sound card was working I hooked up a montior/keyboard to the server and opened a local xfce session. That worked fine. While I had the local session running, I was also able to open a remote session with NXClient and start exaile - which then successfully piped sound to the local card. After disconnecting the monitor/keyboard and moving the box back to its normal spot, though, I was not able to play sound via either an NX or VNC session. Does anyone have any suggestions? Surely it's possible to configure my remote sessions to pipe sound to the server's sound card, right? Or at least get xfce up and running without a monitor or keyboard but with access to the sound card so I can VNC into it? Thanks!
