  • Social Media event Bandwidth requirements

    - by Bob G
    I have an one day event in July 2012, hosting 250 attendees for a social media event. We will be uploading live video to a website, allowing the press to access the web, and some vendors will be showing off their web sites for clients and visitors. The staff will need access for uploading files and information as needed. We had the event last year and tried a cable modem brought in with 2x2 megs just for the streaming video which worked well. I had 4 wireless hot spots, rented from a company 1.5 mbps x 780 kbps, which was were a complete failure. I was assured the 4 hot spots would be enough, but they did not work. What would be the proper way to get the bandwidth required to make the one day event successful? The setting is a Private Country Club where running cables everywhere is very tough.

  • Security against IP spoofing [on hold]

    - by user1369975
    I am pursuing a college project, in which I am running three fake services on three ports to protect the main service (say running at port 80). The concept is that if the user is malicious, he'll try to bring the services down and access the fake services. These ports adopt a blocking process of a connection request and record the IP and port of the client. These are logged and aren't granted access on service on port 80. But what to do if the client spoofs his IP? How can I modify my system?

  • Can't conncet to memcached

    - by DMClark
    We currently have memcached running on CentOS. None of our PHP applications can connect, have tried multiple applications trying to establish access. The most informative PHP error we get is: "Memcache::get() [function.Memcache-get]: Server 127.0.0.1 (tcp 11211) failed with: Permission denied (13) in /var/www/.." memcached 1.4.5 PECL 2.25 We can telnet and it works. IP tables is full access from lo to lo. We've tried this on two different servers with both compiled version and the rpm in CentOS 5.5 and get the same result. Is there anything fairly obvious that we are missing?

  • Interconnection between 2 computers in different networks.

    - by cripox
    Hi, What I want is to connect 2 computers (work and personal) primary for using a software KVM (Input Director or Synergy). Transferring files between them would be a plus. The main issue is that the work computer is in a secured enterprise network, and my personal computer is using a 3G+ modem for Internet access. On the work computer I do not have Internet access (only local network). I want to somehow connect them without to mess up either networks. I want my personal computer to not be seen in the work network. Is it possible? Suggestions: - use a simple UTP cable to connect the 2 computers with each other. Can they each be in both 2 networks without issues? - use some kind of usb cable, if exists

  • New Kingson SSD drive fails after 1 week

    - by user35356
    I upgraded the hard disk in my notebook to a 128GB Kingston SSD V100. Everything worked fine for about a week then out of the blue the notebook would not boot up any more. A black dos-like screen was shown with the options to try and boot normally or attempt to repair windows. Neither option would do anything. When I removed the drive and tested it in an external usb case no other computers are able to access the drive either. Is there anything I can try to fix it myself? The drive is partitioned into three drives and when it's connected through an external usb case to another computer I can see the partitions, just can't access anything on them. Does this mean the drive might be recoverable?

  • How can I retrieve "remembered"(stored) wi-fi password from a win. 7 device?

    - by user180880
    I have access to PC, and I am a standard user. Everything(incl. "show charecters" tickbox at wiriless menu) requires admin access. Now, that said machine is actually like a big tv with touch. Type-stuff is handled by virtual keyboard of windows. I can reach to c:\ProgramData\Microsoft\Wlansvc\Profiles\Interfaces and can see-open files there, which is I assume where passwords stored are. Now the problem is that these passwords is encypted. I'm ok with if there is a way with changing/resetting admin password as well. Considering this device has nothing but massive amounts of usb(yep, not even cd-dvd // rw) the only way is from inside or with usb without admin rights.

  • Windows 7 not showing other computers on network

    - by user24559
    I have several other machines that are on other operating systems (XP, etc.) and they show up just fine on other machines NOT running Windows 7. However, they do not show on the Windows 7 "Network" area. I can directly access them by typing the computer (\\mycomputer), then they show up on the list. However, they don't stick around and when I close Windows Explorer and open it again, the computer is not listed again in Network. There was never a problem using Windows XP where all the machines showed up just fine. This is not an access problem but a listing problem.

  • How to make one CPU to be used simulataneously be three different users

    - by beginning_steps
    As a bootstrapping start-up we are thinking of saving on the IT hardware cost by making more use of the hardware that we have. As a solopreneur I have a laptop config : intel core2duo processor, 3Gb RAM and 250 GB RAM. Now we are planning to increase our team to 3 members. Will like your suggestions on the nest cost-effective step that I can take so that I can use the computing power of the existing laptop to act as a kind of server and then buy to more monitors where the new recruits can do the daily work on and they need to have different login id and access and they dont need access to all the files/applications as are available in my laptop. We use internet intensively to do our day to day activity. Please share you experience, whether you think this is a good ploy or there is any other more effective way of achieving the same result.

  • How to configure permissions for win2008 task running as Network Service to stop/start a service on different system?

    - by weiji
    Well... title says it all, actually. We've got a Scheduled Task set up on a windows server 2003 box running as the Network Service, and the batch file it runs will invoke "sc" to stop and then start a service on another windows box, however sc reports: [SC] OpenService FAILED 5: Access is denied. Running the same batch file via the windows explorer has no issues, and my user account is part of the Administrators group so I believe this is why there are no issues when I try it manually. Is this a permissions thing I enable for Network Service on the first server? Or do I enable permissions for Network Service somehow on the target server? This question (http://serverfault.com/questions/19382/why-sc-query-fails-from-one-machine-but-works-from-another) touches on something similar, but I'm looking for enabling the Network Service to access the service via the scheduled task.

  • Why can I browse to localhost, not to my computer name? (IIS7) [closed]

    - by Lost Hobbit
    I'm not very clued up on IIS, but I'm trying to do something that I thought would be quite simple. In IE, if I browse to http://localhost:80, I am greeted with a pretty picture with a bunch of welcome messages and a big "IIS7", thanks to the graphic designers at Microsoft. In IE, if I browse to http://mycomputername:80, I'm greeted with 404. It may be my fault... perhaps I've done something weird. Chrome replies 404 to either of those. Should this work, and if so, what am I doing wrong, or what can I do to get it to work? What might cause this to happen and how can I fix it? EDIT To add a bit more information. I did find after posting this question that http://localhost:80 was the only URL I could access on my local PC. I could not access any of the virtual sub-directories on localhost via my browser.

  • Why is this server redirecting to another page???

    - by Mike L.
    I am building a site for a client. For a reason unknown to me www.domain.com forwards to www.domain.com/directory/home.html. If i type www.domain.com/index.php it works correctly. I have checked .htaccess there was nothing there, so I set the index to index.php which works fine in every directory other than the root directory. I have root access and have checked the httpd.conf (did a search in VI for the document that I was being redirected to) and anything else I could think of. Where should I look next? The server is a VPS running CentOS 5.5 with multiple domains, has CPanel WHM 11 for root access and CPanel X installed for each domain.

  • What are my options for a secure External File Share in Server 2008 R2?

    - by Nitax
    Hi, I have a Windows Server 2008 R2 machine installed on a home network with a number of files that need to be shared in a few different scenarios. I would like for all three scenarios to have a solution with some sort of encyption to protect the data during transfer. Scenario 1: I need to access files from my laptop (Mac OSX) or another computer outside of the network. This option seems like the easy one to answer in that I could use LogMeIn, the windows VPN, etc. to create such a connection. Scenario 2: I need to provide access to another user with minimal installation / configuration on his or her end. This makes me think of the new FTP 7.5 provided with Server 2008 R2 but i'm not sure of the details: Does it support SSH or some other form of encryption?, can an OSX user connect?, etc. My question here is what are my options? I really just don't know where to get started...

  • [CLOSED] IIS 6 is no longer installed after computer restart.

    - by jarrettcoggin
    [CLOSED] I was doing some maintenance on a build server at work and I changed some various settings (registry settings for custom applications, user permissions, etc.), then I restarted the machine. When the machine came back up, I couldn't access a website that is hosted on this machine, so I went digging around. It seems as if IIS6 was somehow uninstalled, which I know I didn't do. My question is: What would cause this? I've tried to reinstall it, uninstall it, reinstall it again, and nothing has changed. I still have a blank IIS Manager application (inetmgr), and no way to access these websites. BTW, the computer is running Windows Server 2003 R2 x64 Service Pack 2.

  • Why is the word PERSONAL still relevant in the term PC? [closed]

    - by Bill
    I have spent half an hour trying to change an icon on my Win-7-64 machine (Why Can't I Change the Icon). One reasonable suggestion (reasonable in terms of having a solution, not reasonable in terms of having to jump through these hoops for such a basic requirement) was to delete the old icon from the %userprofile% \ Local Settings..., however when I click on this folder in Windows Explorer I am told the folder is not accessible - Access Denied. Well! It's my PERSONAL computer isn't it? Isn't that what PC stands for? It's MY computer - why can't I get access to that folder? It's about time we started calling these machines MCs (Microsoft Computer), or WCs (Windows Computer) - because they sure as hell aint PERSONAL damn computers!!!!

  • Help with SVN+SSH permissions with CentOS/WHM setup

    - by Furiam
    Hi Folks, I'll try my best to explain how I'm trying to set up this system. Imagine a production server running WHM with various sites. We'll call these sites... site1, site2, site2 Now, with the WHM setup, each site has a user/group defined for them, we'll keep these users/groups called site1,site2 for simplicity reasons. Now, updating these sites is accomplished using SVN, and through the use of a post commit script to auto update these sites (With .svn blocked through the apache configuration). There are two regular maintainers of these sites, we'll call them Joe and Bob. Joe and Bob both have commandline access to the server through thier respective limited accounts. So I've done the easy bit, managed to get SVN working with these "maintainers" so that when an SVN commit occurs, the changes are checked out and go live perfectly. Here's the cavet, and ultimately my problem. User permissions. Through my testing of this setup, I've only managed to get it working by giving what is being updated permissions of 777, so that Joe and Bob can both read and write access to webfront directories for each of the sites. So, an example of how it's set up now: Joe and Bob both belong to a group called "Dev". I have the master /svn folders set up for both read and write access to this group, and it works great. Post commit triggers, updates the site, and then sets 777 on each file within the webfront. I then changed this to try and factor in group permission updates, instead of straight 777. Each folder in /home/site1/public_html intially gets given a chmod of 664, and each folder 775 Which looks a little something like this drwxrwxr-x . drwxrwxr-x .. drwxrwxr-x site1 site1 my_test_folder -rw-rw-r-- site1 site1 my_test_file So site1 is sthe owner and group owner of those files and folders. So I then added site1 to Joe and Bobs secondary groups so that the SVN update will correctly allow access to these files. Herein lies the problem now. When I wish to add a file or folder to /home/site1, say Bobs_file, it then looks like this drwxrwxr-x . drwxrwxr-x .. drwxr-xr-x Bob dev bobs_folder drwxrwxr-x site1 site1 my_test_folder -rw-rw-r-- Bob dev bobs_file -rw-rw-r-- site1 site1 my_test_file How can I get it so that with the set of user permissions Bob has available, to change the owner and group owner of that file to reflect "site1" "site1". As Bob belongs to Dev I can set the permissions correctly with CHMOd, but It appears CHGRP is throwing back operation errors. Now this was long winded enough to give an overview of exactly what I'm trying to accomplish, just incase I'm going about this arse-over-tit and there's a far easier solution. Here's my goals 2 people to update multiple user accounts specified given the structure of WHM Trying to maintain master user/group permissions of file and folders to the original user account, and not the account of the updatee. I like the security of SVN+SSH over just SVN. Don't want to run all this over root. I hope this made sense, and thanks in advance :)

  • Ubuntu 9.10 and Squid 2.7 Transparent Proxy TCP_DENIED

    - by user298814
    Hi, We've spent the last two days trying to get squid 2.7 to work with ubuntu 9.10. The computer running ubuntu has two network interfaces: eth0 and eth1 with dhcp running on eth1. Both interfaces have static ip's, eth0 is connected to the Internet and eth1 is connected to our LAN. We have followed literally dozens of different tutorials with no success. The tutorial here was the last one we did that actually got us some sort of results: http://www.basicconfig.com/linuxnetwork/setup_ubuntu_squid_proxy_server_beginner_guide. When we try to access a site like seriouswheels.com from the LAN we get the following message on the client machine: ERROR The requested URL could not be retrieved Invalid Request error was encountered while trying to process the request: GET / HTTP/1.1 Host: www.seriouswheels.com Connection: keep-alive User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; en-US) AppleWebKit/532.9 (KHTML, like Gecko) Chrome/5.0.307.11 Safari/532.9 Cache-Control: max-age=0 Accept: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,/;q=0.5 Accept-Encoding: gzip,deflate,sdch Cookie: __utmz=88947353.1269218405.1.1.utmccn=(direct)|utmcsr=(direct)|utmcmd=(none); __qca=P0-1052556952-1269218405250; __utma=88947353.1027590811.1269218405.1269218405.1269218405.1; __qseg=Q_D Accept-Language: en-US,en;q=0.8 Accept-Charset: ISO-8859-1,utf-8;q=0.7,*;q=0.3 Some possible problems are: Missing or unknown request method.

Your cache administrator is webmaster. Below are all the configuration files: /etc/squid/squid.conf, /etc/network/if-up.d/00-firewall, /etc/network/interfaces, /var/log/squid/access.log. Something somewhere is wrong but we cannot figure out where. Our end goal for all of this is the superimpose content onto every page that a client requests on the LAN. We've been told that squid is the way to do this but at this point in the game we are just trying to get squid setup correctly as our proxy.

  • Apache mod_rewrite driving me mad

    - by WishCow
    The scenario I have a webhost that is shared among multiple sites, the directory layout looks like this: siteA/ - css/ - js/ - index.php siteB/ - css/ - js/ - index.php siteC/ . . . The DocumentRoot is at the top level, so, to access siteA, you type http://webhost/siteA in your browser, to access siteB, you type http://webhost/siteB, and so on. Now I have to deploy my own site, which was designed with having 3 VirtualHosts in mind, so my structure looks like this: siteD/ - sites/sitename.com/ - log/ - htdocs/ - index.php - sites/static.sitename.com - log/ - htdocs/ - css - js - sites/admin.sitename.com - log/ - htdocs/ - index.php As you see, the problem is that my index.php files are not at the top level directory, unlike the already existing sites on the webhost. Each VirtualHost should point to the corresponding htdocs/ folder: http://siteD.com -> siteD/sites/sitename.com/htdocs http://static.siteD.com -> siteD/sites/static.sitename.com/htdocs http://admin.siteD.com -> siteD/sites/admin.sitename.com/htdocs The problem I cannot have VirtualHosts on this host, so I have to emulate it somehow, possibly with mod_rewrite. The idea Have some predefined parts in all of the links on the site, that I can identify, and route accordingly to the correct file, with mod_rewrite. Examples: http://webhost/siteD/static/js/something.js -> siteD/sites/static.sitename.com/htdocs/js/something.js http://webhost/siteD/static/css/something.css -> siteD/sites/static.sitename.com/htdocs/css/something.css http://webhost/siteD/admin/something -> siteD/sites/admin.sitename.com/htdocs/index.php http://webhost/siteD/admin/sub/something -> siteD/sites/admin.sitename.com/htdocs/index.php http://webhost/siteD/something -> siteD/sites/sitename.com/htdocs/index.php http://webhost/siteD/sub/something -> siteD/sites/sitename.com/htdocs/index.php Anything that starts with http://url/sitename/admin/(.*) will get rewritten, to point to siteD/sites/admin.sitename.com/htdocs/index.php Anything that starts with http://url/sitename/static/(.*) will get rewritten, to point to siteD/sites/static.sitename.com/htdocs/$1 Anything that starts with http://url/sitename/(.*) AND did not have a match already from above, will get rewritten to point to siteD/sites/sitename.com/htdocs/index.php The solution Here is the .htaccess file that I've come up with: RewriteEngine On RewriteBase / RewriteCond %{REQUEST_URI} ^/siteD/static/(.*)$ [NC] RewriteRule ^siteD/static/(.*)$ siteD/sites/static/htdocs/$1 [L] RewriteCond %{REQUEST_URI} ^/siteD/admin/(.*)$ [NC] RewriteRule ^siteD/(.*)$ siteD/sites/admin/htdocs/index.php [L,QSA] So far, so good. It's all working. Now to add the last rule: RewriteCond %{REQUEST_URI} ^/siteD/(.*)$ [NC] RewriteRule ^siteD/(.*)$ siteD/sites/public/htdocs/index.php [L,QSA] And it's broken. The last rule catches everything, even the ones that have static/ or admin/ in them. Why? Shouldn't the [L] flag stop the rewriting process in the first two cases? Why is the third case evaluated? Is there a better way of solving this? I'm not sticking to rewritemod, anything is fine as long as it does not need access to server-level config. I don't have access to RewriteLog, or anything like that. Please help :(

  • General website publishing questions involving domain forwarding issue

    - by Gorgeousyousuf
    Even though I have been having a certain level of knowledge and experience about web development I have never interested in obtaining a domain and publishing a website from my own server. Since today I have been struggling with getting my own domain and configuring it utilizing web sources. I started with learning the outline of web publishing process including web server installation, deploying a website for testing purpose,router port forwarding, getting a domain and forwarding domain to my router which will also forward http requests to my web server I am confused about some parts and so far could not get the web site accessed from outside of the network. All I try to do is just for learning purpose so I do not pay much attention to security issues for now. I have Server 2008 and IIS 7.5 installed. I use a laptop and have access to the modem over wireless and my modem is Zoom x6 5590. Well I will continue explaining what I have done so far and what I think will be after each action I did, I have successfully had access to my website on any local computer entering the internal ip address and port pair of the host machine in a browser. Next, I forwarded port 80 of my host machine creating a virtual server like 10.0.0.x(internal ip(static) of the host) - tcp - start port : 80 - end port : 80 in router options. Now I suppose every request that will come to the public Ip on port 80 will be forwarded to my host machine(10.0.0.x) over port 80. So If everyhing went as desired, the website listening on port 80 will accept the request and process the issue and finally respond bla bla bla... I suppose to access my website from outside of the network by entering http://MyPublicIp:80 in a browser but I couldn't accomplish this task by now despite using godady's domain forwarding tool,I see a small view of my website when I click the "preview" button that checks whether the address(http://publicip/Index.aspx) I entered where my domain will be forwarded is available or not. I am sure that configuring domain does not play a role in solving such a problem since using public ip and port matching does not help. So here is the first question, What is the fact that I face this problem? After that, I have couple of question regarding domain forwarding using godaddy tool. Can I forward my domain to a any port for example port 8080 other than default http port 80? Additionally, can I use a sub-domain to forward to a different port of the host? What I want to design is if the client enters www.mydomain.com, website1 will respond over a specified port and after when a client enters info.mydomain.com, another website which listens on different port will respond. I tried to add a sub-domain and forward it to a address like http://www.mydomain.com:8080/Index.aspx with no success. Can I really do that? Finally, what if I have a ftp site listening on the default port 21 and I create a domain like ftp.mydomain.com that will forward to that ftp site address. Is it possible to use sub-domains for ftp site access? I know I am more than confused but no matter whatever and however you reply to me, you will help me have a more clear view on this subject. Thank you very much from now.

  • How do you setup an gsp snippet in grails and with spring-security-core?

    - by egervari
    Hi, I have a block of gsp I'd like to reuse and make into a little gsp snippet: <sec:ifLoggedIn> <g:link controller="user" action="showProfile">My Profile</g:link> | <g:link controller="privateMessage" action="list">Inbox</g:link> | <g:link controller="user" action="showPreferences">Preferences</g:link> | <g:link controller="logout" action="index">Logout</g:link> </sec:ifLoggedIn> <sec:ifNotLoggedIn> <form id="loginForm" action="/myproject/j_spring_security_check" method="POST"> <fieldset> <input type='text' name='j_username' id='username' size="15" /> <input type='password' name='j_password' id='password' size="15" /> <input type="submit" value="Login" class="button" /> <a href="#">Register</a> </fieldset> </form> </sec:ifNotLoggedIn> I have learned that I can use g:render template="_loginStuff" to merge the template in with the rest of the markup. However, doing so with Spring Security results in an error: java.lang.NullPointerException at

Help?

  • How to sanely configure security policy in Tomcat 6

    - by Chas Emerick
    I'm using Tomcat 6.0.24, as packaged for Ubuntu Karmic. The default security policy of Ubuntu's Tomcat package is pretty stringent, but appears straightforward. In /var/lib/tomcat6/conf/policy.d, there are a variety of files that establish default policy. Worth noting at the start: I've not changed the stock tomcat install at all -- no new jars into its common lib directory(ies), no server.xml changes, etc. Putting the .war file in the webapps directory is the only deployment action. the web application I'm deploying fails with thousands of access denials under this default policy (as reported to the log thanks to the -Djava.security.debug="access,stack,failure" system property). turning off the security manager entirely results in no errors whatsoever, and proper app functionality What I'd like to do is add an application-specific security policy file to the policy.d directory, which seems to be the recommended practice. I added this to policy.d/100myapp.policy (as a starting point -- I would like to eventually trim back the granted permissions to only what the app actually needs): grant codeBase "file:${catalina.base}/webapps/ROOT.war" { permission java.security.AllPermission; }; grant codeBase "file:${catalina.base}/webapps/ROOT/-" { permission java.security.AllPermission; }; grant codeBase "file:${catalina.base}/webapps/ROOT/WEB-INF/-" { permission java.security.AllPermission; }; grant codeBase "file:${catalina.base}/webapps/ROOT/WEB-INF/lib/-" { permission java.security.AllPermission; }; grant codeBase "file:${catalina.base}/webapps/ROOT/WEB-INF/classes/-" { permission java.security.AllPermission; }; Note the thrashing around attempting to find the right codeBase declaration. I think that's likely my fundamental problem. Anyway, the above (really only the first two grants appear to have any effect) almost works: the thousands of access denials are gone, and I'm left with just one. Relevant stack trace: java.security.AccessControlException: access denied (java.io.FilePermission /var/lib/tomcat6/webapps/ROOT/WEB-INF/classes/com/foo/some-file-here.txt read) java.security.AccessControlContext.checkPermission(AccessControlContext.java:323) java.security.AccessController.checkPermission(AccessController.java:546) java.lang.SecurityManager.checkPermission(SecurityManager.java:532) java.lang.SecurityManager.checkRead(SecurityManager.java:871) java.io.File.exists(File.java:731) org.apache.naming.resources.FileDirContext.file(FileDirContext.java:785) org.apache.naming.resources.FileDirContext.lookup(FileDirContext.java:206) org.apache.naming.resources.ProxyDirContext.lookup(ProxyDirContext.java:299) org.apache.catalina.loader.WebappClassLoader.findResourceInternal(WebappClassLoader.java:1937) org.apache.catalina.loader.WebappClassLoader.findResource(WebappClassLoader.java:973) org.apache.catalina.loader.WebappClassLoader.getResource(WebappClassLoader.java:1108) java.lang.ClassLoader.getResource(ClassLoader.java:973) I'm pretty convinced that the actual file that's triggering the denial is irrelevant -- it's just some properties file that we check for optional configuration parameters. What's interesting is that: it doesn't exist in this context the fact that the file doesn't exist ends up throwing a security exception, rather than java.io.File.exists() simply returning false (although I suppose that's just a matter of the semantics of the read permission). Another workaround (besides just disabling the security manager in tomcat) is to add an open-ended permission to my policy file: grant { permission java.security.AllPermission; }; I presume this is functionally equivalent to turning off the security manager. I suppose I must be getting the codeBase declaration in my grants subtly wrong, but I'm not seeing it at the moment.
