• Pointcast Alternatives?

  - by kellyllek

  I used to love Pointcast in the early days of the internet; it was a screensaver that, like RSS feeds, brought in all your favorite sources with news articles and stock quotes along with various other info and turned it into a visually interesting screensaver. It was before broadband though and I heard so many work places had to ban it that the company eventually folded. But I wondered if there are any modern day equivalents? I certainly have feed readers and some awesome desktop gadgets that bring in various things like news and weather, and I don't want a whole screensaver like pointcast. But I wondered if anyone out there had other suggestions worth taking a look at; making some kind of feed display of interest, or some other way to turn favorite content into more animated desktop background, etc...

• Using Zentyal to control several servers

  - by user1301428

  I am currently in the process of creating a home server, made up of several virtual machines, each running a different type of server (i.e. a file server, a multimedia server, a firewall and a print server as of now). Today I discovered this new software, Zentyal, which looks interesting for system and network administration. However, I haven't understood one thing: can it be used only with its preconfigured packages or can it also be used to control other servers running other programs (in my case, the four virtual machines)?. Also, would you suggest to use such a program or do you think it's better to control each server on its own?

• Any good resources on setting up an ubuntu virtual machine for web development?

  - by Relequestual

  I'm currently on my placement year at uni with 4 months left. Before working at my current place, I have not used a nix environment for web development and have used WAMP. Over the past year I have found some very interesting new tech that requires a bit more than my shared hosting even to play with (eg node.js, RoR 3). At work we use a Virtual Machine for development, but that's all been set up and configured to match the live servers, and is managed with a Puppet server. Are there any really good resources for setting up and configuring an Ubuntu VM as a web server? Work currently uses Ubuntu so I would assume this is a good OS to use. I do of course know how to use google, but the noise ratio is just too big, so thought I'd ask here, as I know many of you will have a ton of bookmarks. Cheers.

• How can I prevent OpenVPN Client from blocking inbound connections while a tunnel is connected?

  - by joshudson

  We have this machine that we RDP into for using OpenVPN. When a tunnel is connected, it is not possible to RDP into the machine. Should we get disconnected, this is a problem (machine is headless). How can I stop OpenVPN from blocking inbound RDP? I do not have access to the server configuration. If there's anything interesting on the client to check you'll have to tell me how to get at it. I eliminated the possibility of routing issue before asking the question. Only inbound connections cannot be opened. Outbound connections to LAN can be opened just fine. EDIT: Don't bother answering. The problem disappeared without any known changes being made.

• What apps are available for smartphone platforms to allow free calling to the UK and other countries? [closed]

  - by Andrew Ferrier

  On the iPhone, I use MagicJack to get completely free calls over WiFi to US numbers. I'm looking for a similar app to enable me to call UK numbers for free on the iPhone. Does anyone know of one? To make this question of broader applicability to everyone, what apps also allow free calling to other countries? Any smartphone platform (iPhone, Android, Blackberry, Windows Phone) could be useful. Note: I'm talking only about apps that allow completely free calling - the Apple app stores at least are full of apps that allow "cheap" calling. Suspicious apps that require credit card numbers upfront, etc., aren't as interesting.

• How to nmot show any prompts when inserting a USB drive in Windows?

  - by jasondavis

  1) I just found a really interesting program that allows me to use a USB drive as a windows login key. It is called Rohos Logon Key. IF I remobve my USB drive/key from the PC then I can have the PC lock or hibernate or any other option, I have been looking for such a solution for many years but never knew one existed until this and it works much better then I imagined. I do have a couple minor issues though (im using Windows 7 pro). When I remove and then re-insert my USB key, windows prompts me with this dialog here... Generally when I get this I just click on "Continue without scanning" however I am looking for a solution to just make it not even show this at all, is it possible to disable it from showing? 2) I also get this dialog as well when I insert USB drives/key... Would it be possible to not show this as well or have it pick an option by default or anything really?

• SQLite DB borked when opened on a different machine

  - by pruefsumme

  Hello, I'm using SQLite to store some data. The primary database is on a NAS (Debian Lenny, 2.6.15, armv4l) since the NAS runs a script which updates the data every day. A typical "select * from tableX" looks like this: 2010-12-28|20|62.09|25170.0 2010-12-28|21|49.28|23305.7 2010-12-28|22|48.51|22051.1 2010-12-28|23|47.17|21809.9 When I copy the DB to my main computer (Mac OS X) and run the same SQL query, the output is: 2010-12-28|20|1.08115035175016e-160|25170.0 2010-12-28|21|2.39343503830763e-259|-9.25596535779558e+61 2010-12-28|22|-1.02951149572792e-86|1.90359837597183e+185 2010-12-28|23|-1.10707273937033e-234|-2.35343828462275e-185 The 3rd and 4th column have the type REAL. Interesting fact: When the numbers are integer (i.e. they end with ".0"), there is no difference between the two databases. In all other cases, the differences are ... hm ... surprising? I can't seem to find a pattern. If someone's got a clue - please share!

• GitHub Not Accessible from Google Chrome

  - by KPthunder

  Whenever I try to go to GitHub through Google Chrome 11 I get the following error message: GitHub works perfectly fine in Firefox 4: This has been going on for a few weeks. This is a fairly new install of Windows (I don't even remember if I've successfully got on to GitHub on this installation with Chrome in the past). I don't even use GitHub for hosting my own code personally, but this has proven annoying in that I can't even access other people's projects through Chrome! Does anybody know what is going on here? An interesting side note: The Sight extension for Chrome doesn't work either! It worked on my old installation of Windows but not on this one. Is my Chrome installation just screwy? I've tried disabling certain other extensions but nothing seems to change.

• How can I select a default interactive console in pyDev?

  - by dorian

  Using PyDev 2.7.1 in Eclipse 3.7.2, when I hit Ctrl-Alt-Enter to open a new interactive console, I get a dialog asking me what type of console I'd like to start ("Console for currently active editor", consoles for Python, Jython, Iron Python etc.). Now this selection dialog has no default entry and keyboard selection doesn't work, meaning that I have to use my mouse every time I need a new console, which is kind of tedious. I've checked Preferences - PyPev - Interactive Console, but found no interesting options there. Is there any possibility to define a default interactive console type so that I just have to hit Return when the dialog pops up or, even better, skip this question altogether?

• Mail Secure & Stable Open Source Mail Server

  - by Fanar ALHAYALI

  I have asked question on http://stackoverflow.com/questions/9868426/i-need-to-know-which-email-server-i-have-to-use and someone tell me my question would be better on serverfault. I know that this is a common question and asked many times. but there are so many available mail servers that i am not able to decide the one. Kindly tell that which is the Secure, Stable and fast open source mail server for Centos or Redhat Server. Is there any guide which can be used to deploy the mail server with all its components e.g. smtp, pop3, imap, spam, calender server, antivirus, DNS Setting. Currently I'm using sun messaging V6 which installed on Solaris 10 and my boss ask me to make a report for the best mail server today in the marketing? I tried to have a look on Google but I couldn't find interesting information for my report. Any advice would be appreciated.

• Can I run my OS from a DVD?

  - by Dave D

  I'm thinking of ways to get around the high cost of hard drives lately. I was thinking an optical jukebox would be interesting (though more expensive than just buying a hard drive), then thought I've heard of OS's run from DVD so why not boot from a Blue-ray drive. I think a smaller OS like a linux flavor would work. I'd like to know if there's a way I could burn Windows 7 to DVD for this use. Just curious. Anyone know if this is possible? Thanks, Mac

• Wireless slow, but very odd

  - by Logman

  I have a HP Pavilion dv6 laptop, internet through the wireless timeouts. Even though it connects fine to the AP/router. The computer had a virus (searchnu?) and I backed up the usual and restored the laptop to factory image. Problem is after the restore the internet through the wireless the same still... and connected via wired and everything worked fine. I was able to update the whole system. Internet worked perfect, speed great. But the wireless still was pitiful. Ping tests with wireless are interesting: Google= 18ms Gmail= 18ms Yahoo= 1023ms 8.8.8.8=30ms Microsoft= Request Timed Out Bing= Request Timed Out msn= Request Timed Out even though I get 18ms with google, the pages take a long time to load. Is this a root kit? is it the wireless card in the laptop?

• Use a media player in Linux just to play files from an iPod device (no sync, no manage, just play)?

  - by Somebody still uses you MS-DOS

  I have an ipod classic 160gb, that I sync with my machine at home. I use Linux at work, and want to just plug my ipod and just listen to the tracks, with all the playlists and such. I don't want to sync nothing, I just want to listen to the tracks as if I was using the ipod itself. Why? Because this way I can use the usb port. So, I don't want to manage my ipod in Linux, I just want to listen to the tracks on it in Linux, like it was a local library but it's instead in my ipod. (I've tried gtkpod, it works to show my files, but I can't play, shuffle, etc. It would be interesting to have a complete audio software to handle everything like it was a local library)

• Hiding a directory through the FAT table

  - by hennobal

  I've looked into the FAT file system, trying to find a way to make a directory hidden from view of the user. This has been done with malware previously, so it should be possible. The SpyEye trojan hid inside a directory C:\cleansweep.exe\ which was only reachable through the command line. I know deletion is possible by substituting the first character of the directory in the FAT table with 0xE5, but then it will not be accessible. Any ideas on how the scenario from SpyEye can be recreated? Any filesystem is interesting, but ideally FAT or NTFS.

• Advice for outdoor wifi hardware and topology

  - by Robot

  I haven't setup any wifi networks other than an access point or two at any single location, so I'd like advice on how to setup an outdoor/weatherproof network in an area approximately 150 feet by 200 feet. The interesting thing is there are a pair of pools in the middle of the coverage area. Here is a picture: blue is pool, green is coverage area, yellow is building with wired access. Can anyone advise me on weatherproof APs, antennas and placement for best coverage of the pool deck? I've looked at the Meraki stuff, but I'm thinking it's overkill.

• How to tune Windows 2008r2 and IIS to maximize single file download speeds?

  - by uSlackr

  We recently put up an IIS site (on WinSvr 2008r2) that is used almost exclusively for downloading files over the internet. The data exists as a large collection of .zip files ranging from 1MB - 35GB in size. We want to allow a lot of downloads during a day (more than 500GB) but have implemented an outbound ASA throttle at 60mbps in order to preserve bandwidth for other uses. The total link speed is 100mbps. Here's the interesting part: While we can serve up multiple downloads to hit the 60mbps cap, we cannot get any single download to exceed 2.5M bytes/sec (20 Mbits/s). Is there any TCP or IIS tuning we can do to push up individual download speeds? Or something else to look at?

• Web Content Filtering for Windows Clients

  - by djoyce

  I'm working with a small business to solve a bunch of problems. One is their Windows 7 POS registers need to have web access restricted to only three remote support sites, but the back office machine needs an unfiltered connection. I'd like something I can install and configure on the few registers to block all but those few sites. In a perfect world this would restrict the normal register user, but the admin user would not be filtered. Free is best, if it works, but a small fee would be alright too. Microsoft's Family Safety filter is close, but requires a Windows Live account, which isn't ideal, but may be alright. Anyone use this in a small business environment? I'd prefer something easily managed at the local machines. K9 Web Protection is interesting and I'm going to look into it more. Are there other options? Seems like someone would have made something simple like this as an open source project, but maybe not.

• Server goes offline. What to look for?

  - by Jonathan Sampson

  I'm using a new virtual server through GoDaddy, and this morning I received a call from the powers that be informing me our website was offline. After confirming this, I requested a power cycle through our GoDaddy control panel, and within a minute or two the server was back online. I made the call, and reported the news that we're back up. Of course, a couple minutes later we're down again. I tried connecting through PuTTy, and it takes forever to prompt me for a username, and each successive prompt takes a long time to come up. I'm using CentOS. So my questions are: How can I determine the cause? What types of things can I do to prevent this in the future? One interesting, and perhaps relevant, observation is that yesterday our bandwidth consumption was about 20% greater than our top figures from the past month.

• Lightest way to run Google Hangouts Chrome app on Mac

  - by jadengore

  I recently transitioned to Safari because I'm really tired of how Chrome hogs memory and drains my battery like crazy. The only thing that has been keeping the Chrome icon open is the Hangouts plugin. Basically, I am looking for the lightest way to run Hangouts on my Mac. By light, I mean the least amount of RAM usage, and preferably a way to do it without Chrome open/light version of Chrome that only opens extensions. Any suggestions? EDIT: Another thing I noticed was that Hangouts ignores your default browser if links are sent to you by chat, and when clicked they open in Chrome. My question doesn't relate to this at all, but I found it interesting...

• how to get a decent emacs setup on linux

  - by Hersheezy

  I am currently interested in switching from vim to emacs. One of the more compelling reasons for this is the smooth integration with a unix environment. The most experienced emacs users I have seen have a bash prompt at the bottom of their window, with stdout going to a buffer right above it. They then interact with the output of programs such as grep in interesting ways. I am on Ubuntu 10.04 and the default emacs environment does not seem to do much for me in the way of integration. For example, in the M-x shell mode, output from basic commands like ls produce lots of strange characters and hitting the up arrow does not go to previous commands. Any recommendations on a good direction to go in?

• Can't Remote into Windows Server

  - by Brian

  Hello, I have a Dell server wired into the router. I was able to connect to it with my laptop (laptop is wireless) before my router died. My verizon router went kaput, and I got everything else back up and running on the wireless network other than the remoting in feature, even though I can access the server through windows explorer just fine. Any ideas why? What do I need to check? UPDATE: Interesting scenario, Network Discovery is off; I turn it on and save, but for some reason, even after that, network discovery is turning itself off... no idea why that is happening? Thanks.

• What is your approach to draw a representation of your network ?

  - by Kartoch

  Hello, I'm looking to the community to see how people are drawing their networks, i.e. using symbols to represent complex topology. You can have hardware approach, where every hardware unit are represented. You can also have "entity" approach, where each "service" is shown. Both are interesting but it is difficult to have both on the same schema (but this is needed, especially using virtualization environment). Furthermore, it is difficult to have complex informations on such representation. For instance security parameters (encrypted link, need for authentication) or specific details (protocol type, ports, encapsulation). So my question is: where your are drawing a representation of your network, what is your approach ? Are you using methodology and/or specific softwares ? What is your recommendations for information to put (or not) ? How to deal with the complexity when the network becomes large and/or you want to put a lot of information on it ? Examples and links to good references will be appreciated.

• is there any valid reason for users to request phpinfo()

  - by The Journeyman geek

  I'm working on writing a set of rules for fail2ban to make life a little more interesting for whoever is trying to bruteforce his way into my system. A good majority of the attempts tend to revolve around trying to get into phpinfo() via my webserver -as below GET //pma/config/config.inc.php?p=phpinfo(); HTTP/1.1 GET //admin/config/config.inc.php?p=phpinfo(); HTTP/1.1 GET //dbadmin/config/config.inc.php?p=phpinfo(); HTTP/1.1 GET //mysql/config/config.inc.php?p=phpinfo(); HTTP/1.1 I'm wondering if there's any valid reason for a user to attempt to access phpinfo() via apache, since if not, i can simply use that, or more specifically the regex GET //[^>]+=phpinfo\(\) as a filter to eliminate these attacks
