  • SSH ForceCommand example - require a user to enter a token before getting shell access?

    - by consolibyte
    I'd like to prompt a user for some piece of information before they get to their BASH shell when they're logging in via SSH. Ideally, I'd like to execute a script which prompts them for information, check that the information is correct, and then if it is drop them to a shell. So, think: ssh [email protected] password: xxxx do you agree to the terms and conditions of use? enter yes or no: yes OK, here's your shell: # Can anyone provide an example of how to do something like this?

  • Utility to Monitor Kill / Restart Rogue Process?

    - by Sean O
    Hi, I need a Windows (XP/7) utility to continuously monitor always-running processes and kill them (and optionally restart them) if they hang. There are a lot of interactive tools out there (Sysinternals, most notably). But I have a program on a little-used workstation that needs to run continuously and reliably, both of which are not two of its strong suits :) It requires continual babysitting, and I'd rather just have a monitoring utility (even a paid one) that can kill/restart it on definable conditions -- e.g. CPU 80%, Status of "Not Responding", etc.

  • What is wrong with my .Htaccess file? I'm trying to redirect permanently my whole site to the index.

    - by SocialAddict
    This is giving me a 500 internal server error. Any suggestions? I have tried various examples but I think I'm missing something... RewriteEngine On RewriteCond %{request_uri}!^ /index\.htm RewriteRule ^(.*) /index\.htm [R=permanent,L] It displays the homepage if I navigate there but anything that meets the conditions (all appart from index.htm gives the server 500) EDIT: with the above code it now doesnt give any 500 errors but it doesnt redirect for any pages

  • Set HTTP condition for redirect rule

    - by Török Gábor
    A have a redirect rule in my .htaccess that forwards agent from A.html to B.html using the following pattern: Redirect 301 /A.html http://mysite.com/B.html Since the Redirect directive requires to set the target host, is it possible to let this rule prevail only on a specific host? I have both a test and deploy domain, and only want it on the deploy domain. I can set HTTP conditions for Rewrite rules, but how can I for HTTP Redirects?

  • Ubuntu shutdown hook?

    - by ???
    I want to check 10+ local Git repositories if they have any unpushed commit, before shutdown. (I always forgot to push them, so later, the next morning I came office and back home again) I think maybe the shutdown process can check some conditions to meet, if any condition is not met, then give the user the choice to continue to shutdown or just cancel. Then, I can write something to hook the shutdown to check my Git repository to push.

  • trigger a DNS change in Active directory

    - by Paddy Carroll
    Can I get solar winds to change a DNS alias in Active directory based upon a specific set of events or conditions? I have a collection of applications that use hostnames in combination with database names in order to resolve database connections, problem is that they haven't considered how a failover would work in practice so I want the product to provoke a change in DNS to point the apps at the right place if we get into a failure situation. Can it be done?

  • How to fix Visual Studio 2008 freeze?

    - by Mnementh
    My Visual Studio 2008 freezes under some conditions. First, after a restart it is fine, but once it starts updating IntelliSense and counting down items it stops on the same number (the number slightly changed with further changes in the project). After that I get a sure freeze for: right-click in the code to get a context-menu changing from Debug to Release and vice versa quitting visual studio After a freeze I have to kill the process. Any idea what is wrong here?

    - by doug
    I have an audio file with a very bad recording (recording was made in very noisy conditions, at a conference). My recorder was too far from the speakers. Do you have any idea about how to improve the sound quality? Do you know any good resource for that?

  • Seek bounced emails tracker

    - by justSteve
    I'm preparing to implement a .net webapp on my IIS7 box where code generates emails and sends them using the native SMTP server. What facilities/utilities exist to alert me to non-successful conditions. Specifically i'm looking to automate some way to highlight the exceptions that need attention as opposed to disciplining myself (staff) to 'check the logs'. thx

  • Custom Rule Action in Outlook

    - by Zee99
    How to create my own custom action in Microsoft Outlook Rules? In Outlook, when creating a rule in the Rules wizard, we set first the conditions and then set the actions that we choose from a list of predefined actions. Is there a way to add my own action to the existing actions programmatically? I also see an action called custom action, when i click it it opens up a small window with an empty combobox, can i add my custom action there, and how?

  • Is it a good idea to put "screen -r" in my .bashrc?

    - by marcusw
    I'd like to use screen to keep ssh sessions alive on my server. It would be nice if I could automatically resume any running session for my user when I log in. The straightforward way to do this would be adding "screen -r" to my .bashrc, and this seems to work fine. I'm just wondering if this will break anything under conditions which I haven't tested yet. Anyone with experience here who can tell me whether this is what I should do?

  • Data center Rack space providers with Dedicated/Unmetered 10Gbps+ packages?

    - by Bob Marley
    The only provider I know is FDC and I was hoping you guys could help me compile a list for comparison? The only requirements are that they 1) have 42U rack space and 2) have dedicated/unmetered 10Gbps+ packages. I don't care where they're located or anything else as long as those two conditions are met. If you feel like sharing your opinions and/or experience with anyone too that'd be great, although it's not required. Thanks guys.

  • bridge traffic limiting via tc

    - by jackhab
    I have a Linux machine running as a bridge simulating various network conditions. I use tc for this. Introducing delays or packet loss is quite simple but I got into trouble trying to configure bandwidth limiting. Can you, please, show me how to limit all the traffic going through my bridge without any special rules and condition, simply limit it to 1Mb/s? Thanks. PS Your favorite link to tc tutorial will be appreciated.

  • Which to install: Apache Worker or Prefork? What are the (dis-)advantages of each?

    - by Aron Rotteveel
    Based on the descriptions for both the Prefork and Worker MPM, it seems the prefork type is somewhat outdated, but I can't really find a proper comparison of the two types. What i'd like to know: What are the differences between the two versions? What are the (dis-)advantages of each server type? Are there any basic guidelines on which type to choose based on the conditions? Are there any big performance differences between the two?

  • SQL: Using a CASE Statement to update 1000 rows at once

    - by SoLoGHoST
    Ok, I would like to use a CASE STATEMENT for this, but I am lost with this. Basically, I need to update a ton of rows, but just on the "position" column. I need to update all "position" values from 0 - count(position) for each id_layout_position column per id_layout column. OK, here is a pic of what the table looks like: Now let's say I delete the circled row, this will remove position = 2 and give me: 0, 1, 3, 5, 6, 7, and 4. But I want to add something at the end now and make sure that it has the last possible position, but the positions are already messed up, so I need to reorder them like so before I insert the new row: 0, 1, 2, 3, 4, 5, 6. But it must be ordered by lowest first. So 0 stays at 0, 1 stays at 1, 3 gets changed to 2, the 4 at the end gets changed to a 3, 5 gets changed to 4, 6 gets changed to 5, and 7 gets changed to 6. Hopefully you guys get the picture now. I'm completely lost here. Also, note, this table is tiny compared to how fast it can grow in size, so it needs to be able to do this FAST, thus I was thinking on the CASE STATEMENT for an UPDATE QUERY. Here's what I got for a regular update, but I don't wanna throw this into a foreach loop, as it would take forever to do it. I'm using SMF (Simple Machines Forums), so it might look a little different, but the idea is the same, and CASE statements are supported... $smcFunc['db_query']('', ' UPDATE {db_prefix}dp_positions SET position = {int:position} WHERE id_layout_position = {int:id_layout_position} AND id_layout = {int:id_layout}', array( 'position' => $position++, 'id_layout_position' => (int) $id_layout_position, 'id_layout' => (int) $id_layout, ) ); Anyways, I need to apply some sort of CASE on this so that I can auto-increment by 1 all values that it finds and update to the next possible value. I know I'm doing this wrong, even in this QUERY. But I'm totally lost when it comes to CASES. Here's an example of a CASE being used within SMF, so you can see this and hopefully relate: $conditions = ''; foreach ($postgroups as $id => $min_posts) { $conditions .= ' WHEN posts >= ' . $min_posts . (!empty($lastMin) ? ' AND posts <= ' . $lastMin : '') . ' THEN ' . $id; $lastMin = $min_posts; } // A big fat CASE WHEN... END is faster than a zillion UPDATE's ;). $smcFunc['db_query']('', ' UPDATE {db_prefix}members SET id_post_group = CASE ' . $conditions . ' ELSE 0 END' . ($parameter1 != null ? ' WHERE ' . (is_array($parameter1) ? 'id_member IN ({array_int:members})' : 'id_member = {int:members}') : ''), array( 'members' => $parameter1, ) ); Before I do the update, I actually have a SELECT which throws everything I need into arrays like so: $disabled_sections = array(); $positions = array(); while ($row = $smcFunc['db_fetch_assoc']($request)) { if (!isset($disabled_sections[$row['id_group']][$row['id_layout']])) $disabled_sections[$row['id_group']][$row['id_layout']] = array( 'info' => $module_info[$name], 'id_layout_position' => $row['id_layout_position'] ); // Increment the positions... if (!is_null($row['position'])) { if (!isset($positions[$row['id_layout']][$row['id_layout_position']])) $positions[$row['id_layout']][$row['id_layout_position']] = 1; else $positions[$row['id_layout']][$row['id_layout_position']]++; } else $positions[$row['id_layout']][$row['id_layout_position']] = 0; } Thanks, I know if anyone can help me here it's definitely you guys and gals... Anyways, here is my question: How do I use a CASE statement in the first code example, so that I can update all of the rows in the position column from 0 - total # of rows found, that have that id_layout value and that id_layout_position value, and continue this for all different id_layout values in that table? Can I use the arrays above somehow? I'm sure I'll have to use the id_layout and id_layout_position values for this right? But how can I do this? Ok, guy, I get an error, saying "Hacking Attempt" with the following code: // Updating all positions in here. $smcFunc['db_query']('', ' SET @pos = 0; UPDATE {db_prefix}dp_positions SET position=@pos:=@pos+1 ORDER BY id_layout_position, position', array( ) ); Am I doing something wrong? Perhaps SMF has safeguards against this approach?? Perhaps I need to use a CASE STATEMENT instead?

  • vBulletin 5 + lighthttpd url rewriting

    - by Boots
    I'm trying to get vBulletin 5 up and running under lighttpd but I'm having some problems with url rewriting. Here is the apache .htaccess provided by vBulletin. <IfModule mod_rewrite.c> RewriteEngine On RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule ^(.*)$ index.php?routestring=$1 [L,QSA] #needed because admincp is an actual directory. RewriteRule ^(admincp/)$ index.php?routestring=$1 [L,QSA] </IfModule> If this helps, this is the IIS config provided by vBulletin <?xml version="1.0" encoding="UTF-8"?> <!-- This file is to support redirection in IIS. It is harmless if you are running under Apache --> <configuration> <system.webServer> <rewrite> <rules> <rule name="Main Redirect" stopProcessing="true"> <match url="^(.*)$" ignoreCase="false" /> <conditions logicalGrouping="MatchAll"> <add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true" /> <add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true" /> </conditions> <action type="Rewrite" url="index.php/{R:1}" /> </rule> <rule name="Admincp" stopProcessing="true"> <match url="^(admincp/)$" ignoreCase="false" /> <action type="Rewrite" url="index.php/{R:1}" /> </rule> </rules> </rewrite> </system.webServer> </configuration> Anyone have any suggestions as to the lighttpd url.rewrite equivalent? All my experiments have failed thus far. I'm running lighttpd-1.4.31-1 I tried this but it didn't work. I think it has something to do with me not properly emulating [QS] in the .htaccess url.rewrite-once = ("^(.*)$" => "index.php?routestring=$1", "^(admincp/)$)" => "index.php?routestring=$1") This has gotten me closer but not fully functional yet. url.rewrite-if-not-file = ("^(.*)$" => "index.php?routestring=$1", "^(admincp/)$)" => "index.php?routestring=$1")

  • Using ssd intensively. Should we worry?

    - by vvavepacket
    I'm currently using conventional HDDs like the 5200 rpms, browsing a lot, my folder and files are scattered, torrenting always and I'm not fond of optimization like disabling cache, cleaning temp Files , etc. My question is, given the above conditions (no disable of cache, seeding always in torrent, downloading torrent) is it safe to use SSD? I'm pretty worried about cycles but I read an article wherein it says its safe since it will usually wear out for 10 years given that you always write heavily and continuously. Thanks

  • Small Business Server 2011 and Remote access to documents

    - by Tim Long
    Assume I'm working away from the office; its a hotel computer Windows 7, Office 2010 and fast - so the best possible conditions. Using Companyweb - Every time I open a document, I have to go through the logon process - seems odd to have to do that. Is this a 'by design' feature or is something wrong with my configuration? When I do open the documents, are they being stored somewhere locally and should I be looking to delete on this computer - or are they in a temporary file?

  • Why should I use a switched network over routed?

    - by SRobertJames
    Now that routers are affordable, why should I build a network using Layer 2 switches, which degenerate to broadcasting under poor conditions, and not just use real routing at Layer 3? Edit: Got some great replies. Let me clarify the question: Of course, at the lowest level, you want to plug your end nodes into a switch, not a router (as demonstrated by AlReece). I'm referring to switches which are used to bridge traffic between segments - that is, switches connected to other switches.
