• Fake demostration software for command line

  - by Joe

  I'm looking for some software that would be useful for giving demonstrations. I regularly have to show the effects of scrips ect to classes while talking about their effects, and equaly regularly I have finger trouble and have to rewrite various commands - wasting class time and general energy. I'd like to be able to record a sequence of commands in advance, and then play them back at the speed of my choosing. So I might have a file that containes the commands: echo "hello world!" ls ls -l ls -l | sort I'd like to be able to play these commands back by typing similar ones in. So I'd have a blinking command prompt and if I typed 'echo "hxxx' the command prompt would read home$echo "hell and if I typed any other letters the terminal would fill up with the remainder of the command until I press enter, when it executes the command. The point is that even if I screw up the command when typing it, the command that I'd prepared in advance would be executed. My question is - does similar software exist for giving demonstrations? or even, is this an easy thing to script up...? EDIT - two quick things first of all I'm on osx - but it would be nice to get a general solution for other people who arrive here from google. and second a lot of the comments/answers are concentrating on, in effect, making it fast and easy to enter long commands by means of hotkeys and the like. Actually I'd like it to at least look like I'm typing live - that's why I put in the bit about the one-to-one keymapping, but I don't think I explained that quite as well as I could have...

• Plug-in device to front USB computer *sometimes* restarts

  - by Mark A. Nicolosi

  I've got a strange problem that very occasionally (maybe once a month) when I plug-in something to the front USB on my computer, the computer suddently restarts. This also happens when I touch the front USB ports sometimes. This has been going on for a few years and a lot of the components in my PC have changed. I thought it was my home wiring, but I moved last year and it still happened. I thought maybe it was the motherboard, but that was upgraded 9 months ago and it still happens. I thought it was my case, but I changed that recently and it still happens. I thought maybe it was my PSU, but I upgraded that yesterday and it still happens. I'm pretty sure this is an electro-static thing, but I thought that modern computers have protection against this sort of thing. Maybe I should move my case off the floor (carpet) and stop wearing songs all the time. Edit: Just to clarify this is a computer that I built. The components have been upgraded throughout the years and it's not much the same computer anymore. This doesn't happen very often, but it is annoying, because I don't know what the cause is. Anyone have any ideas?

• How do you permanently disable the 'This Connection is Untrusted' page on Firefox

  - by TheIronChef9

  I'm going insane. Can someone please help me to COMPLETELY DISABLE the 'This Connection is Untrusted' page on Firefox. Facts: I am running Firefox 23.0 on an Ubuntu machine (downloaded and installed ubuntu today) It is a work computer and I have to use my employer's proxy While visiting Webpages/webapps like Gmail or Google brings up the 'This Connection is Untrusted' page and I have to go through the whole tedious task of selecting 'I understand the Risks' and add Exceptions, etc. etc. The fact is, I don't care about the risks. I would rather this computer melt into the ground than have to see that page ever again. I want to dance naked in untrusted pages and not give a damn about the consequences. I just never want to see that page again. Ever. For some sites (eg. wikipedia), the css doesn't load and I end up seeing them in plain text. As a result these sites are completely useless. Wasted hours trying to solve this for stackoverflow.com. These issues happen on the Firefox on my Windows XP machine as well (also using the same proxy). I don't want to export/import certificates or create exceptions for every site that shows this bloody page. I just want this page gone. I don't want Firefox to tell me what's safe and what's not. Also, my system time and date are correct. I've also tried the lies on this page too with no good results. Edit: I've also tried the whole going into the Advance-Certificates-validation setup page and unchecked 'Use the Online Certificate Status Protocol (OCSP) to confirm the current validity of certificates' checkbox. Nothing happened even after restarting firefox or rebooting. I need help. Thanks.

• PassEnv does not find ENV variables

  - by quodlibetor

  I've got this /etc/profile.d/myfile.sh: export MYVAR=myval I also have a PassEnv MYVAR line in a <virtualhost> section of an apache conf dir. That lets me do things like: $ echo $MYVAR myval $ python >>> import os; os.getenv('MYVAR') 'myval' $ sudo echo $MYVAR myval $ sudo -i root# echo $MYVAR myval But then, despite that being the case I get: root# /sbin/service httpd restart /sbin/service httpd restart Stopping httpd: [ OK ] Starting httpd: [Mon Oct 22 14:44:02 2012] [warn] PassEnv variable MYVAR was undefined [ OK ] And all of my attempts to access MYVAR from within my wsgi scripts just don't work. Thoughts? Am I doing something obviously wrong? EDIT for more detail I've got a swarm of computers/VMs and a swarm of developers working on a swarm of projects. I need a simple central place to keep environment information, the most common is the "environment" (dev/stage/prod). The scheme that we've got (modifying *.wsgi programmatically) is turning out to be more fragile than we'd like. The main options that I see are: put things in the shell environment put things in other config files Getting things into the shell environment is the best, because we won't need to write yet more duplicated "what is my environment" code.

• Working with different PHP version at the same time, php_value extension_dir not working?

  - by Gremo

  I need both PHP 5.4.7 and 5.3.17 running on Windows 7 x64 with Apache 2.2.23. This is my virtual host configuration: <VirtualHost *:80> DocumentRoot "C:/WAMP/Apache/htdocs/php54" ServerName php54.local PHPIniDir "C:/WAMP/PHP54" LoadModule php5_module "C:/WAMP/PHP54/php5apache2_2.dll" php_value extension_dir "C:/WAMP/PHP54/ext" <Directory "C:/WAMP/Apache/htdocs/php54"> Order allow,deny Allow from all </Directory> </VirtualHost> The PHPIniDir and LoadModule directives work fine and using phpinfo() inside my script prints the right PHP version. But I need to load extensions, and this is where it fails. php_value extension_dir should be C:/WAMP/PHP54/ext but it's (default one) C:/php. What I'm missing here? EDIT: Of course I can set this value directly in C:/WAMP/PHP54/php.ini, but I prefer passing it using vhost configuration: ; Directory in which the loadable extensions (modules) reside. ; http://php.net/extension-dir ; extension_dir = "./" ; On windows: extension_dir = "C:/WAMP/PHP54/ext"

• Windows Home Server 2011, No disks "suitable for a backup destination"

  - by Scott Beeson

  I recently installed Windows Home Server 2011 and love it. However, when I try to set up server backups, it says no suitable disks are available. Initially, before I set up my RAID, it found one of my twin drives and said it would work. Once I set up the mirroring, that one is no longer available (obviously). However, I have an internal SATA 1TB drive and an external USB2.0 1TB drive hooked up. Both are recognized by Disk Management. WHS11 still says nothing suitable for backups. The two drives details are as follows: Edit to clarify: The system partition is on Disk 0, not listed below. The two below are the two that SHOULD be available for system backups. Disk 1: Dynamic "Data" (D:) 931.51 GB NTFS, Healthy Disk 3: Basic 200 MB Healthy (EFI System Partition) "Backup" 930.66 GB NTFS, Healthy (Primary Partition) What's a bit odd is that in Disk Management the "Backup" volume does not show a drive letter, even though I assigned Z: (which is reflected in "My Computer". I also cannot make this a dynamic disk as it says it's unsupported by the device.

• sub application and virtual directory file permissions

  - by Zeus

  I have a website setup in IIS7, exampledomain.com. Under the application exampledomain.com lives a sub application cms. In a rather convoluted way, we have content in our cms system in this sub-app, under cms\content\{generatedfoldername}. So to access an image in this content, the full URL would be http://www.exampledomain.com/cms/cms/content/{generatedfoldername}/image.jpg, (yes, cms twice...) and this works just fine. Now, we have a virtual directory under the parent website, called stuff which points at the content of the cms. So I should be able to get to the image using the url http://www.exampledomain.com/stuff/{generatedfoldername}/image.jpg. Unfortunately this gives a server 500 error "There is a problem with the resource you are looking for, and it cannot be displayed." Whilst you do have to log into the cms system to access any of the admin pages within, I don't think the image files are protected by login, or else the first example URL wouldn't work, right? Also it's a server 500 error, rather than a 403. I'm sure I must be missing something obvious here- will the virtual directory be using the permissions defined in the parent application, or the subapplication to which it is pointing? Or is there some other permissions I may have missed? Sorry, that was a bit long, thanks for reading all the way down here! (I also must point out that I'm pretty new to the server management stuff.) edit: also, we have <location path="." inheritInChildApplications="false"> specified in the webconfig of the parent app, so it's hopefully not the issue described in this config file hierarchy article.

• How to know who accessed a file or if a file has 'access' monitor in linux

  - by J L

  I'm a noob and have some questions about viewing who accessed a file. I found there are ways to see if a file was accessed (not modified/changed) through audit subsystem and inotify. However, from what I have read online, according to here: http://www.cyberciti.biz/tips/linux-audit-files-to-see-who-made-changes-to-a-file.html it says to 'watch/monitor' file, I have to set a watch by using command like: # auditctl -w /etc/passwd -p war -k password-file So if I create a new file or directory, do I have to use audit/inotify command to 'set' watch first to 'watch' who accessed the new file? Also is there a way to know if a directory is being 'watched' through audit subsystem or inotify? How/where can I check the log of a file? edit: from further googling, I found this page saying: http://www.kernel.org/doc/man-pages/online/pages/man7/inotify.7.html The inotify API provides no information about the user or process that triggered the inotify event. So I guess this means that I cant figure out which user accessed a file? Only audit subsystem can be used to figure out who accessed a file?

• Same script, different behavior [migrated]

  - by Antoine_935

  I just stumbled upon an interesting bug... Still trying to figure out what is exactly happening. Maybe you can help. First, the context. I'm currently building yet another man to html converter (for some reasons I won't motivate here, but I need it). So, have a look at the screenshot below (see the link), more precisely at the outlined spots. See? On the upper shell, I have &lt ; and &gt ;, that is, escaped html. While on the shell below I have < and directly. But as you can see (or do I seriously need looking glass ?), the command man 2 semget | webmanneris the same on both sides, as is the which webmanner. The two are executed roughly at the same moment, with no modification made to the script between. [Oops, cannot post pictures just yet... Here comes the link] http://aspyct.org/media/webmanner-bug.png But the shell below is older (open about 1 hour ago). Newer shells all print out &lt ;. So my first guess was that it somehow had a cached reference to the old inode of the file, or old blocks or whatever. So I modified parts of the script, at the start and then at the end, to print different messages. And, surprise, the message shown up on both terminals. But still, same difference between &lt ; and <. I'm confused... How to explain that behavior? I'm working on a OSX 10.8 (Mountain Lion) EDIT: OK, there is one big difference: the shell below uses ruby 1.9.3, while above is 1.8.7. Is there any known difference in string handling between the two versions ?

• Windows 7: Dual Monitor Issue

  - by sdoca

  I have a Dell laptop with a docking station and two external monitors hooked up. I'm running Windows 7 64 bit. Originally, the two monitors were the same - Dell 1908FP. I have replaced one of them with an HP LA2405. I have set the HP 24" (1920 x 1200 connected via DVI port) as montior 1 and extended to use the Dell 19" (12080 x 1024 connected via VGA port) as monitor 2. I have set my power plan so that when the laptop is plugged in, it will turn the monitors off after 10 minutes, but it will not put my laptop to sleep. However, now that I have the HP monitor, when I unlock my laptop and the monitors come back on, all my windows are resized and shifted to the top left corner of the HP monitor as if they had been resized for display on the smaller Dell monitor. A co-worker has the exact same laptop and monitor configuration but doesn't experience this issue, so I figure there's some configuration that's different but we can't find it. I haven't been able to find any mention of a similar problem doing an internet search, but I'm not really sure what terms to use in my search. Anybody have any suggestions as to what may be causing the issue? OS setting? Monitor setting? EDIT: My laptop is using the Intel Graphics and Media Control Panel/drivers.

• How is it possible to list all folders that a particular user/group has permissions on?

  - by Lord Torgamus

  Is it possible to list all folders/files that a given group has explicit permissions on, for a machine running Windows Server 2003? If so, how? It would be nice to see inherited permissions as well, but I could do with just explicit permissions. A little background: I'm trying to update groups/permissions on a test server. One of the groups, Devs, wasn't implemented correctly when it was created, and my goal is to remove it from the system. It has been replaced by LeadDevelopers, which has permissions on many — but naturally not all — of the same folders. I want to make sure that I don't accidentally orphan any folders or cause any other issues when I remove Devs. It did have some admin-level permissions. EDIT: The answers so far — at least *cacls and AccessEnum — provide a way to find out which groups/users have permissions on known directories/files. I actually want the reverse of this behavior: I know the group, and I'm looking for the directories/files for which the group has permissions. Also, as I noted in a comment, the Devs group is not itself a member of any other group.

• Recovering a broken NTFS filesystem?

  - by OverTheRainbow

  A much-needed Windows Update broke a Vista laptop that was running fine until then: After booting up, Windows displays "Please wait..." but it never goes anywhere. I waited for a couple of hours, there is a bit of disk activity, but it didn't work out in the end. I booted with the Vista DVD, chose "Repair your computer" which said that there was nothing wrong :-/ Next, I booted it up with a Linux USB keydrive, and ran Gparted 0.8.1 (which includes ntfsresize v2011.4.12AR.4 libntfs-3g) which displays a bunch of warnings for the NTFS partition where the Vista system is located such as: ntfs_mst_post_read_fixup: magic: 0x00000000 size: 1024 usa_ofs: 0 usa_count: 65535: Invalid argument Record 16 has no FILE magic (0x0) Next, I ran ntfsfix /dev/sda2, which said: Mounting volume... OK Processing of $MFT and $MFTMirr completed successfully. NTFS volume version is 3.1. NTFS partition /dev/sda2 was processed successfully. Next, I rebooted Vista, which did a CHKDSK, before rebooting. But I'm still getting nowhere with "Please wait..." Before I copy the user's data to another host and reinstall Vista from a DVD, does someone know what I could try? Thank you. Edit: In case someone else has the same issue... After the BIOS, hit F8 and choose "Repair your computer", followed by "Toshiba HDD Recovery". In addition to a 1,5GB partition labelled "WinRE", the hard disk contains a second partition labeled "Data" from which the application will fetch a system image and reinstall it in the "Vista" partition. Make sure you copy your data out of the system partition before doing this.

• Pull network or power? (for contianing a rooted server)

  - by Aleksandr Levchuk

  When a server gets rooted (e.g. a situation like this), one of the first things that you may decide to do is containment. Some security specialists advise not to enter remediation immediately and to keep the server online until forensics are completed. Those advises are usually for APT. It's different if you have occasional Script kiddie breaches. However, you may decide to remediate (fix things) early and one of the steps in remediation is containment of the server. Quoting from Robert Moir's Answer - "disconnect the victim from its muggers". A server can be contained by pulling the network cable or the power cable. Which method is better? Taking into consideration the need for: Protecting victims from further damage Executing successful forensics (Possibly) Protecting valuable data on the server Edit: 5 assumptions Assuming: You detected early: 24 hours. You want to recover early: 3 days of 1 systems admin on the job (forensics and recovery). The server is not a Virtual Machine or a Container able to take a snapshot capturing the contents of the servers memory. You decide not to attempt prosecuting. You suspect that the attacker may be using some form of software (possibly sophisticated) and this software is still running on the server.

• Live Messenger SimilarityTable2 file

  - by adrianbanks

  I am trying to free up some space on my laptop's hard disk and am using a tool (SpaceMonger) that will show me a treemap of the whole disk. The problem I have comes from Live Messenger's SimilarityTable2 file. I have no idea what it is for, but I know that it is a sparse file, meaning that it shows as taking up 8GB of disk space, but actually only takes up 132KB of space on disk. The problem is that because SpaceMonger thinks this file is 8GB, it swamps the other files and takes up most of the treemap, making it hard to see the other files that really are large. Is this file safe to delete? If not, how do I make its actual size on disk match its reserved size? If that's not possible, how can I make SpaceMonger (or another treemap tool) use the real size of the file and not the reserved size? EDIT: I've just realised that I have some NTFS junctions set up, meaning that the same set of directories appear twice. Is there any way to stop this happening as well?

• Windows 7 / TCP/IP network share guide - looking for to resolve failure to mount lacie network drive but works on XP,Linux,Mac.

  - by Rob

  Can anyone advise me of a really good, readable, Windows 7 TCP/IP network share guide, book, or reference. I want this because I cannot mount my Lacie 2big ethernet network drive in Windows 7 (32 bit home), but I can mount it in Windows XP Home 32bit, Ubuntu Linux 10.04 and Apple MacOS X. This drive is being mounted via the accompanying Lacie Ethernet Agent in XP (which I believe uses "Bonjour" protocol), on Mac and Linux it works without further need for software. Another Super User user has the same problem, but no answer: Trouble accessing network drives in Windows 7 I hope my take on the question shows a better willingness to investigate and do some digging - and therefore invite some suggestions to help with this. The drive is detected by Windows 7 (i.e. speech bubble "network drive found") but on trying to open an Explorer window, this remains blank with the Windows busy pointer. I'd prefer not to reinstall Windows 7 to see if that cures the problem, I'd rather understand what is happening/not happening, perhaps even compare differences with Windows XP. Suggestions, please for such guides or even the original problem itself.

• Many clients on a wireless AP for UDP broadcast packets

  - by distorteddisco

  I asked this question on StackOverflow and was directed over here, so I'd appreciate any advice. I'm deploying a smartphone application as part of a live music performance that depends on receiving UDP broadcast packets from a wireless access point. I'm guessing that between 20 and 50 clients will be connected at any one time. I'm aware that a maximum of 20 clients per access point is advised, but as the UDP broadcast packets are ground through the LAN, how would I be able to link multiple APs together? I'm looking for recommendations on a suitable AP for this. The actual data transmission rates are very low - only a few kB/s - as I'm just sending small messages to the smartphone apps, and there will be no WAN internet connection. I tried it with a few connected peers on an adhoc wireless connection without any problems, but ran into dropped packet issues on an old WRT54G running ddwrt, though it's in pretty rough shape. What's the best way to do this? I suppose I could limit concurrent wireless connections to 20 clients... but more would be nice. EDIT: I should also say that it's purely one-way communication; the smartphone application is only receiving broadcast packets, not sending anything.

• Concurrent users with Quickbooks?

  - by airietis

  I work in a company with 3 people who regularly use the same Quickbooks file. However, they work remotely on different networks. I need to implement a solution that allows all three of us to access Quickbooks at the same time remotely (and each make changes at the same time). We have a spare desktop PC that can be utilized as a server. So, my question is: what is the cheapest and most hassle-free solution to solving this problem? I've considered using application cloud hosting, however, it is very expensive ($40 per user a month) and we are on a tight budget. Is it possible to install Quickbooks on my own server, and have them connect to it remotely? If so, what is the best way to accomplish this? Remote desktop protocol? Or is there a built in feature for this with Quickbooks Premier 2013? EDIT: As MDMarra mentioned, I am looking for a solution that offers true simultaneous access. Will using a dedicated server and having users connect to a VPN be a viable solution?

• Windows 7 Laptop Randomly Sleeping

  - by Josh Arenberg

  I'm running Windows 7 64-bit on a Lenovo laptop, and I have a problem wherein after I've put it to 'sleep' once, it will seemingly without any reason or warning go back to sleep every 10 to 15 minutes after that. Each time it wakes back up just fine, and you can happily continue on. However, 10 or 15 minutes later, it just drops out into sleep mode. I don't see any errors in the system logs. I don't think it's related to heat ( since it's not rebooting ). When I check the system event log, I can see where the machine goes to sleep, but it simply says "reason: application API", and doesn't indicate which app ( brilliant ). I don't see any errors from hardware or anything relating to sleep in the application log that would point to what is going on either. How can I find out which app is triggering this? EDIT: I confirmed that temperature wasn't the issue. I think it's important to keep in mind that this condition only happens after the first sleep. If I reboot, the problem goes away until I put it to sleep, after which it sleeps on it's own every few minutes. Is there no way to capture which app is calling the sleep routine?

• auth user and exec a node app only with apache?

  - by Blame

  I couldn't find an answer on the web and I'm trying for days now so I hope that someone with more experience with apache can help me out. Iam writing an web editor and the user should be able to edit a file that is on the server in a directory the user has access to. The problem Iam facing is that I need to authenticate against the system users (shadow/passwd). So the user should be able to login whith a system account and then the node app which does all the logic should be started with the users rights. I hope to get this working without any additional script and only with Apache. I found out two things: I can use mod_auth_pam to authenticate the user There is a mod called suEXEC which can exec the node app with a specified user The problem is that I have to hard code which user is used by suEXEC but I want to decide when the user logs in. Is there any way to authenticate a user against the shadow/passwd and then exec a prog with the users rights? I dont want to run the node app as root and the user should only be able to access his own files. Any help would be appreciated! Thanks, Kodak

• Recovery disk Windows 8 HP Pavilion g6

  - by fpghost

  I recently purchased a HP Pavilion g6 laptop running Windows 8. I want to either obtain the Windows 8 ISO or make some kind of recovery disk that would allow me to restore the system if things go wrong. The HP Pavilion comes with the 'HP Recovery Manager' which I thought may do the job, but on running it and putting in a DVD-R as requested it seems to just hang for a number of hours without doing a thing (the disk sounds like it's spinning for a few minutes but then goes silent). I then tried 'recdisc.exe' but I get the error System Repair could not be created The device reported unexpected or invalid data for a command. (0xC0AA02FF) Next I obtained my Windows 8 product key using the software ProduKey thinking this would allow me to go to the Microsoft website and download the Windows 8 ISO, but as far as I can tell all that is available is the upgrade which can be used if one is running something like Windows 7. Can anyone advise? EDIT: after a reboot recdisc.exe did work; I think the problem was due to some Windows updates needing a reboot, but never the less I would like a full Windows 8 ISO if possible.

• How do I connect to and factory reset a Catalyst 3560 Switch?

  - by Josh

  My company just bought another company. In their server room they had some older hardware, which I would like to repurpose. One of these is a Cisco Switch: C3560G-48TS-S. I found some instructions about this switch here but this is not a guide for a beginner. I have no idea how to connect to this thing to begin running the commands. It says Configure the PC terminal emulation software for 9600 baud, 8 data bits, no parity, 1 stop bit, and no flow control. But I can't find anything on how to do this (assuming with telnet?) or even what program to use. I also don't know how to find the IP address of the device to connect to it. My research also says once I get in there, I need to run clear config all Is this the right command? Also, what if I can't get the username and password for these devices? Is there some way to factory reset (my only experience is with devices that have a hardware reset button) EDIT: I should note that when I push the button on the front the three lights blink, which according to the documentation indicated the switch is configured and "not available for express setup"

• java memory allocation under linux

  - by pstanton

  I'm running 4 java processes with the following command: java -Xmx256m -jar ... and the system has 8Gb memory under fedora 12. however it is apparently going into swap. how can that be if 4 x 256m = 1Gb ? EDIT: also, how can all 8Gb of memory be used with so little memory allocated to basically the only thing running? is it java not garbage collecting because the OS tells it it doesn't need to or what?

• Can I split one ethernet line coming out of my wall into multiple separate lines?

  - by Burteçin 'Turk' Sapta

  Hi all and thanks in advance. I'll start with some background. I live in an apartment which provides internet service included in the rent. They use company called pavlov for the internet http://pavlovmedia.net/ wireless seems to be working fine but wired connection is at least %30 faster. Ethernet, cat5 outlet is built in the wall, and there is only 1 outlet in each room. I would like to take this 1 outlet coming out the wall and multiply it into 4 wires, for desktop, playstation, tv and laptop without loosing any internet bandwidth. i have absolutely no idea weather this line is coming from a switch or a router but i have been researching Ethernet splitter, routers, switches, hubs and haven't found a solid answer. what is the best solution for me? thank you once again! EDIT: ok this picture cleared few things http://www.home-network-help.com/images/home-network-expanded.jpg so seems that an ethernet switch is to ethernet as a USB hub is to USB. what is really 10/100Mbps Network Switch and what is the cap?

• Apache in MAC OS X

  - by Michal K.

  I have problems with apache on MAC OS Lion 10.7.5. I have VirtualHosts: <VirtualHost *:80> ServerName devel.dev DocumentRoot /var/www </VirtualHost> <VirtualHost *:80> ServerName test.dev DocumentRoot /var/www <Directory "/var/www"> Options Indexes FollowSymLinks AllowOverride All Order allow,deny Allow from all </Directory> </VirtualHost> I have configured httpd.conf to ServerRoot = /usr/htdocs (empty directory). test.dev and devel.dev says always "It works!". Why ? In /var/www I have index.php which contains only one letter "k" (for tests). Edit, more info: I have restart apache milion times. File with VirtualHosts is included. error.log: [Tue Oct 02 20:03:55 2012] [notice] caught SIGTERM, shutting down [Tue Oct 02 20:03:55 2012] [warn] mod_bonjour: Cannot stat template index file '/System/Library/User Template/English.lproj/Sites/index.html'.
