• program for drawing diagrams

  - by ldigas

  I need to draw a few diagrams that describe the working of some smaller programs (nothing real, but some exercise to illustrate some points). They're supposed to be 'old kind' diagrams, like you remember from the "old school of programming" - I gather some users here will know what I mean. And it's be good if they have ready blocks for program units, IF conditions, FOR/DO loops and such ... So, anyone knows of an application for such ? (I've tried Visio which I have on my work machine (for whatever reason ... I sure didn't put it there) ... but it is "too visual" for this kinda thing ... I just want to draw a few simple black on white diagrams ... nothing special or in colours).

• Routing traffic to another internal network

  - by Jason

  OK, so here is the scenario. I have 4 Locations connected with an MPLS. I have installed an ASA at the primary location which is 10.20.1.0. Traffic is fine internally and to the world, however... I can't route traffic over the MPLS to another network. It is being blocked by an implicit deny rule even though there is a rule to allow any to any less secure interface (it should be using the same interface in/out, right?). I have a static route for the network in and the ASA can ping it - Just not traffic on the internal network of the ASA. -Jason

• Redircting to a url that has a question mark in it?

  - by dkmojo

  I have a somewhat strange problem. A client has moved their site to Wordpress. They use a service for link exchanges that has a Wordpress plugin. The issue is that the new links pages use a query string to display the correct content and I cannot figure out how to redirect the old URLs correctly. Old URLs look like this: domain.com/link/category-name.html The plugin makes them look like this in WP: domain.com/links/?page=category-name.html How in the world can I get the redirect to work properly? Here's what I have tried: Redirect 301 /link/actors.html http://www.artisticimages.biz/links/?page=actors.html Redirect 301 /link/actors.html http://www.artisticimages.biz/links/%3Fpage=actors.html Redirect 301 /link/actors.html http://www.artisticimages.biz/links/\?page=actors.html But none of those have worked. Any help is greatly appreciated!

• Blocking internet poker applications

  - by Matthew Savage

  I 'look after' the wireless internet for a cafe where I live, and we've noticed that there's quite a substantial slow down of internet speeds when certain users are playing internet poker. I've put in filters to block any HTTP traffic referencing gambling and poker etc, however I want to be able to block any applications (i.e. poker clients) which don't use HTTP. I've tried searching around for a list of poker clients and perhaps their ports, but have had no real luck. Does anyone know what these might be?

• Unable to configure Ruby with readline

  - by Liam Berg

  1) ./configure --prefix=$HOME/.packages --with-readline-dir=$HOME/.packages 2) configure: WARNING: unrecognized options: --with-readline-dir I am trying to setup the most up-to-date version of Ruby on my webhost (I do not have sudo access). Line 1 is the configure command I used for Ruby and Line 2 is the first printed line after executing 'configure'. I've googled this issue and found other people with the same problem but there aren't any real solutions. There are no warnings or errors when configuring/compiling readline-6.1. I am pretty stumped, any help/insight would be greatly appreciated. Thanks ahead of time.

• One domain hiding two servers

  - by George DSeas

  For our SaaS web-app we have two identical servers in two geographically separated data centers. FOO_1 is the production server and does real-time (MySQL master-slave) replication to its backup F00_2. We want our users to always go to THEFOO.COM which somehow points to the production server. So even if FOO_1 dies, we can just switch THEFOO.COM to redirect to FOO_2 so the failure is transparent. This switch can be manual or automatic but without failback (if FOO_1 somehow becomes available again). Is there a way to do this with DNS? I am getting stuck with ANAME and CNAMEs configuration. We don't use sub-domains, just straight domains. If not, what are other options? Does it make sense to just have a web server at LOVELY_FOO.COM and just redirect all traffic? I also looked at load balancers but didn't see a solution for across data centers/network providers.

• How to set WAN side buffers for WRT54GL running Tomato Firmware

  - by Vickash

  I've recently set up a machine running m0n0wall to try and fight buffer bloat and do some traffic shaping. It was more convenient (geographically speaking) to connect the cable modem directly to my old WRT54GL, then pass everything to the m0n0wall machine and have that do the real routing work. It took a bit of work, but it's working pretty well. I have a cable connection. I have m0n0wall set up to utilize only 90% of the specified speed of my subscription, which is fine. But I've noticed that at certain times of the day (possibly when my true bandwidth drops below that 90%), there's more latency if the connection is used heavily, and traffic shaping doesn't seem to work as well. I suspect this is caused by the buffers on the WRT54GL still being unnecessarily large. If the connection is working as expected, they won't get filled, but in times of reduced bandwidth they would. Does anyone know the command I need to execute, on the WRT54GL running Tomato Firmware, to reduce the buffers on the WAN interface to the minimum size possible?

• tomato firmware unstable when I am connected to Chromecast

  - by Graviton

  I have an Asus RT-N12D1, and I installed the tomato firmware by shibby ( version tomato-K26-1.28.RT-N5x-MIPSR2-112-Max.trx). However I found that the connection can be really unstable. Whenever I stream youtube videos on TV via Chromecast ( I tried both the cast from iPad and Win7, both can reproduce the problem), the router will frequently restart itself, leading to a loss of connection and subsequent reconnection. I want to get this problem fixed, but I don't know how. Is there anyway where I can troubleshoot what is the real problem, or is there anyway I can collect enough log information so that I can then present to the original developer for a fix ( maybe)?

• afp/smb transfers caps at 2 megabytes/sec, wireless N

  - by CQM

  I wanted to transfer files between two mac computers. The network is wireless-N and both computers have wireless-N modules in them. The problem is that when I transfer files between them, via file sharing (afp) the network speed caps at 2 megabytes/sec. Just downloading files from the internet I can get faster speeds, so this isn't a constriction of my wifi bandwidth, it appears to be a constriction of the protocol being used. My wifi-n is set to 130mbits, so I should see real world transfer speeds around 12-16 megabytes/sec I did this command on both computers sudo sysctl -w net.inet.tcp.delayed_ack=0 which is supposed to lower tcp overhead, but this did not affect it. How can I get the speed I am expecting?

• Samsung 830 very slow benchmark numbers

  - by alekop

  I just bought a new SSD, and installed a fresh copy of Windows on it. I didn't see any noticeable difference in boot times, app start-up times, so I decided to benchmark it. Asus P7P55D-E Intel i5-760 Samsung 830 256GB SATA III Windows 7 Ultimate 64-bit The Windows experience index gave the drive a 7.3 rating, but real-world performance is not particularly impressive. Any ideas why the numbers are so low? UPDATE: It turns out that SATA III support is turned off by default on the P7P55D motherboard. After enabling it in BIOS (Tools - Level Up), the scores went up: Read Write Seq 325 183 4K 16 49 IOPS 32K 28K It's an improvement, but still far below what they should be for this drive.

• Problem with Windows activation on a VM (Virtual machine)

  - by Daisetsu

  I backed up a number of laptops to virtual machines before they are to be re-purposed, in case I need the data at some later time. While the Physical to VM processes worked fine I am encountering issues on some of the VMs. When I boot them I get an error message saying I MUST activate windows in order to login. This is expected because the hardware changed (from physical hardware to virtualized hardware). I click the OK button and expect to be prompted with ways to activate, windows sits there for quite a while then tells me that "Windows has already been activated". I click OK at that message and get take back to the beginning where I am asked to activate Windows. I have done some fairly intensive googling but haven't been able to find a real solution. EDIT: The laptops with the issues are 2 Sony Vaios, I believe that they have the OEM version of the OS originally installed by the factory.

• Apache VirtualHost running very slow on OS X 10.7 (Lion)

  - by jwerre

  I've set up a few virtual hosts in Lion and it's running very slowly. NameVirtualHost *:80 <VirtualHost *:80> ServerName localhost DocumentRoot "/Library/WebServer/Documents" </VirtualHost> <VirtualHost *:80> ServerName dev.local DocumentRoot "/Users/me/mysite" <Directory /Users/me/mysite> Order allow,deny Allow from all </Directory> </VirtualHost> then in /etc/hosts I added 127.0.0.1 dev.local Everything works fine but it's sooooo slow — 5 or so second to reload a simple "Hello World" html page. Here's is the strange part. If I make a symbolic link of the site in my ~/Sites folder (ln -s ~/mysite ~/Sites/mysite) and navigate to http://localhost/~me/mysite It's nice and fast the way it should be.

• Streaming video from a point-and-shoot camera that doesn't support it

  - by egasimus

  I have a Canon IXUS 120is (PowerShot SD940) - a nice digital camera that's a couple of years old. It does record fairly decent video, but, alas, can't function as a webcam - and I need to stream video over the Web. I've installed CHDK on it, and while it's quite flexible, doesn't seem to provide a solution to my problem. I suppose that the video footage is written to the SD card in real time - is there a hack that allows me to monitor the file as it is written, and broadcast its contents over the Internet? Perhaps connecting its the camera's slot to my laptop's card reader via SDIO? I'm running Windows, but I'm roughly familiar with Linux; another question has suggested a file-to-/dev/video driver - do such tools exist?

• Why are Linux-based operating systems considered safer than Windows?

  - by echoblaze

  I hear that Linux-based systems are better for security. Apparently they don't have viruses and do not need antivirus software. Even my university claims this - they refuse to have Windows on their servers, which is a real shame because we wanted to use the .NET framework to create some websites. The only reason I can see Linux being safer is because it's open-source, so bugs theoretically would get caught and fixed sooner. I know a bit about how operating systems work, but haven't really delved into how Linux and Windows implement their OS. Can someone explain the difference that makes Linux-based systems more secure?

• sendmail user unknown - debian lenny

  - by Rimian

  My php's mail() function just stopped working a short while ago. It's started returning FALSE. I am not much of a sysadmin so please forgive my ignorance. I set my php.ini send_path option to: "sendmail_path = /usr/sbin/sendmail -t -i" and restarted apache. Then, I learnt how to test sendmail like so: sudo /usr/sbin/sendmail -bv [email protected] [email protected]... deliverable: mailer esmtp, host example.com., user [email protected] The example email is a real mail box. I have also seen unknown user messages in the mail log. Can anyone please help me debug this? Cheers, Rim

• Mac OS X Terminal get in Macintosh HD? For using Git and Github

  - by user63119

  I wanted to get started with using Git and Github especially for installing Web software to my htdocs directory. htdocs is the folder in which you put all your websites that then run by using MAMP -- Apache server, PHP, MySQL and stuff. This not the real problem though, the problem is I am in the terminal and see this: imac-van-jeroen-*******-2:~ JeroensiMac$ And using cd ~ or cd .. just results back in the line above, which is usual. The problem is that all my applications and everything really is not on my user but in the Macintosh HD. Macintosh HD/applications, or Macintosh HD/applications/MAMP/htdocs/ I want to be in the Terminal and go to my Macintosh HD (is this referred to as being superuser?). I want to know if this is just my fault for installing everything on my Macintosh HD instead of Macintosh HD/users/JeroensiMac/~. Also I would like to know if its possible at all, and I am just missing something. And If I am not doing anything wrong is it safe to use Git(Github) with directories in my Macintosh HD?

• Win7 to Win7 Remote Desktop Not working, Xp to 7 working fine

  - by vlad b.

  Hello, I have a small home network and recently i tried to enable remote desktop for one of the pc's. I have a mix of Windows 7, Windows Vista and Xp runing alongside ubuntu, centos and others (some virtual, some real). I have a few Windows 7 pc`s that can be connected to using remote desktop from inside and outside the network (port redirects on routers, etc, etc) and some Xp ones. The trouble is when i tried to do the same thing to a Win7 laptop i discovered i can't connect to it from another win7 pc inside the home network. To sum it up Working: xp -- win7 not working: win7 -- win7 What i tried - disable and enable remote desktop (my computer - remote settings) - removing and adding users to the remote settings window - adding a new user to the machine, administrator or 'normal' user - checking the firewall settings on the machine and set 'allow' to remote desktop for both 'home/work' and 'public'networks Any tips on what should i do next? It displays ' .. secure connection' and after that the window with 'Your security credentials did not work' and it lets me try again with another user/password..

• When to move into a CRM system?

  - by Dan

  I have a client that is currently managing around 5000+ contacts via Outlook. There is also a BES Express installation in place. There are a couple problems. First, there is a corrupt contact in there somewhere that is preventing either a cabled or over the air sync of the complete list to a blackberry. The second, is that it just seems to be getting a bit unruly. They currently have a license for ACT, which I'm trying to get them to move into, but at what number does the contact list need to be at to migrate away from using Outlook/Exchange and into a real CRM solution?

• Win 2008 r2 -- client and server are both behind a NAT

  - by Mike Dehari

  I am new to win2008. Have Win2008 R2 installed. Need to know how a client system (Win7), using remote desktop, terminal server, or whatever windows 2008 provides to connect to it (as a user or an admin). Both the client (Win7) and the server (win2008) are inside a NAT (with 192.168......... addresses). Both have real internet addresses (they are in different cities 173.64.......). How can I use the internet from the client (Win7) to connect to the server (Win2008). On both systems, I have "allowed other systems to connect". I am familiar with tcp/ip, ports......etc.

• Remotely turn on a device that is powered off?

  - by njboot

  Verbatim from the interview between Brian Williams and Edward Snowden last night: Snowden: Any intelligence service in the world that has significant funding and a real technological research team can own that phone [refering to Williams' iPhone] as soon as it connects to a network; it can be theirs. Williams: Can anyone turn it on remotely if it's off? Snowden: They can absolutely turn it on with the power turned off on the device. I concede Snowden's first point, fine. But the last? Does Snowden's last claim, that a powered off mobile device can be remotely turned, have any merit? It seems highly improbable and seemingly impossible.

• Task bar remains visible with "Auto-hide the task bar" checked in Windows 7.

  - by Corey

  It's about time that I figure this out. I can say with a pretty high confidence that I have experienced this issue in all consumer versions of Windows since XP. I keep "Auto-hide the task bar" checked to maximize screen real estate. Every once in a while, the task bar will refuse to hide while individual windows will continue to act as if that option is checked (by falling under the task bar). For years, I have fixed this by rebooting. Of course, I cannot predict the timing or frequency of the problem, so the process becomes burdensome. I want to know how this can be fixed without rebooting. It has affected my on multiple machines using multiple versions of Windows, so I cannot be the only one who is bothered by it. Can anyone help me solve this?

• Symbolic links and 7zip

  - by Fire Lancer

  I'm trying to compress a folder into a .7z archive. This folder contains symbolic links to some other stuff outside the folder (both directories and files). Apparently 7zip just archives the link it's self which is not what I intended. Is there a way to tell 7zip that I want it to archive the stuff that it links too, not the link its self (so if there is a symlink name "foo" which points to "C:\stuff\foo" I want it to include the "C:\stuff\foo" stuff in the archive in place of foo, not a "0 byte" symlink... Failing that is there any reasonable around it, apart from adding the files and folders in question? Including the stuff through the symlink there's like 10 000 files, the large proportion of which are via symlinks so adding them all individually would take hours... I'm thinking mayby a program that creates a staging folder with the real files in it then passes that to 7zip, or just an archiver that does handle them better?

• How to send Windows key over VNC to Linux from Windows?

  - by MJBoa

  Alright, so I'm running Linux with AwesomeWM on my home machine. I'm running x11vnc on that machine and I want to connect to it from a windows machine. So it suffices to say that I need the Windows key for my home machine to function. I really like TightVNC, but I have found that only RealVNC is able to send the Windows key presses that I need. My problem is that RealVNC is sorely lacking customization and I feel it's inferior to TightVNC and unusable. I know that Ctrl-Esc sends the windows key press in Tight but then I can't use it as a modifier key. Useless. Anyone have any ideas? I don't think it's a server issue since I've tried Tightvnc server on the linux machine and it still doesn't work, at least in TightVNC. It works with Real anyway. Oh and UltraVNC doesn't work either.

• SQL 2008 Mirroring, how to failover from the mirror database?

  - by Luis

  I have configured a database mirroring setup in SQL 2008 using the High-safety, Synchronous mode, without automatic failover. I don't have a Witness instance. Regarding high availability, I understand Mirroring is a better strategy than Log Shipping (faster and smoother failover), and cheaper than Clustering (because of license and hardware costs). According to the MS docs, to do the failover you need to access to the Principal database and in the "Mirror" options click the "Failover" button. But I want to do this from the Mirror database, because what would be the benefit as all this setup is being done in case the Principal server knocks down? Evidently I am missing something. If Mirroring is not a solution for server downtime (as would be Clustering, if I understand correctly), then which practical (i.e. real world examples) cases would benefit from Mirroring for high-availability purposes? Thank you very much for your response! I really need some enlightment.
