  • Router reporting failed admin login attempts from home server

    - by jeffora
    I recently noticed in the logs of my home router that it relatively regularly lists the following entry: [admin login failure] from source 192.168.0.160, Monday, June 20,2011 18:13:25 192.168.0.160 is the internal address of my home server, running Windows Home Server 2011. Is there anyway I can find out what specifically is trying to login to the router? Or is there some explanation for this behaviour? (not sure if this belongs here or on superuser...) [Update] I've run both Wireshark and netmon for a while on my home server. Wireshark captured the traffic, but didn't really show anything useful (or nothing I could make use of). A simple HTTP GET request is sent from the server (192.168.0.160) to the router (192.168.0.1), from a seemingly random port (I've seen examples from 50068, 52883), and it appears to do it twice in quick succession (incrementing port by 1), about every hour. Running netstat around the time of the failure didn't show anything (probably too long after anyway). I tried using netmon as it categorises by process, so I thought it might show a corresponding process for the port. Unfortunately, this comes in under the 'unknown' category, meaning it's basically just a slower, less useful Wireshark. I know there's not much to go on here, but does this help in anyway?

  • Window 2003 Server - Logon Failure error message in Event Viewer

    - by user45192
    Hi guys, I received alot of event logged in the event viewer with this message. I notice is always the same user id which encounters this error. The user id is use by an application to access the database. However, this account does not exits on this server. How do I trace the services/program use by this user id which causes these error messages?

  • Install a program from the network

    - by Gomibushi
    In Windows there is a place under the Control Panel called Get Programs and Install a program from the network (in Win 7 at least), possibly a slightly different name in Vista, but it was there too. The question is basically: How do you publish programs to that so users can go there and install? Bonus follow up: Is it a good way to deploy optional programs? (Compared to using GPO's.) In Windows 7 you can go to Control Panel, Programs, Programs and Features, and on the left hand menu: Install a program from the network.

  • Why are email transfers between mail servers often not encrypted? Why aren't users warned about it?

    - by AmV
    Users can often choose if they want to access their email provider (such as Gmail) using a secure channel (e.g. using HTTPS). However, to the best of my knowledge, when it comes to mail-server-to-mail-server communications, most emails are still transferred in plain text and not encrypted, making it possible to anybody on the network to read their content. Are there any technologies that give the user some guarantees that his emails are sent securely from end to end ? Why not let the user know when encryption is not supported and let him choose if he wants his email to be still delivered ?

  • Setting permissions on user accounts

    - by Ron Porter
    We would like to lock a couple of accounts to prevent even domain admins from resetting the password without already knowing the current password. From what I can see in the permission sets, this looks possible. Anything I've found on the subject recommends against altering default permissions, but doesn't go into detail why. Assuming that domain admin retains the ability to reset passwords without knowing current passwords is it reasonable to prevent password resets on the domain admin account and maybe a couple of others? If not, why not?

  • Got Hacked. Want to understand how.

    - by gaoshan88
    Someone has, for the second time, appended a chunk of javascript to a site I help run. This javascript hijacks Google adsense, inserting their own account number, and sticking ads all over. The code is always appended, always in one specific directory (one used by a third party ad program), affects a number of files in a number of directories inside this one ad dir (20 or so) and is inserted at roughly the same overnight time. The adsense account belongs to a Chinese website (located in a town not an hour from where I will be in China next month. Maybe I should go bust heads... kidding, sort of), btw... here is the info on the site: http://serversiders.com/fhr.com.cn So, how could they append text to these files? Is it related to the permissions set on the files (ranging from 755 to 644)? To the webserver user (it's on MediaTemple so it should be secure, yes?)? I mean, if you have a file that has permissions set to 777 I still can't just add code to it at will... how might they be doing this? Here is a sample of the actual code for your viewing pleasure (and as you can see... not much to it. The real trick is how they got it in there): <script type="text/javascript"><!-- google_ad_client = "pub-5465156513898836"; /* 728x90_as */ google_ad_slot = "4840387765"; google_ad_width = 728; google_ad_height = 90; //--> </script> <script type="text/javascript" src="http://pagead2.googlesyndication.com/pagead/show_ads.js"> </script> Since a number of folks have mentioned it, here is what I have checked (and by checked I mean I looked around the time the files were modified for any weirdness and I grepped the files for POST statements and directory traversals: access_log (nothing around the time except normal (i.e. excessive) msn bot traffic) error_log (nothing but the usual file does not exist errors for innocuous looking files) ssl_log (nothing but the usual) messages_log (no FTP access in here except for me)

  • Srvany Starts but Application doesn't

    - by mharran
    I used Instsrv and Srvany as to create a service on W2008; the Srvany service starts okay but the application does not start. The application is TeamSpeak 3 btw. I don't think it's an issue with my W2008 setup as I have a previous version of the application set up the exact same way and running perfectly. Also, I have no problem manually starting the application even when I copy and paste into the 'Run' box the path used for the application by Srvany. I looked at Events but nothing there except notification that the service has entered the running state, didn't really expect any errors as the service has started even though the application hasn't. Any suggestions on what could be the problem?

  • Can't connect back to the wireless network after the password was changed

    - by 7777
    Family changed the network password and some other network settings after new computers were brought into the house because apparently they wouldn't work with what we had. Actually an off-site tech remotely changed it, and I have no idea what he did. My laptop detects the network (it shows up under available networks) but whenever I try to connect it says: Windows is unable to connect to the selected network. The network may no longer be in range. Please refresh the list of available networks, and try to connect again. I wish I could give more details, config settings, but frankly I have no idea what I'm looking for. This is XP (also, not a password issue, I know the password, it's just that I have no idea where to enter it, etc.)

  • How to find on the Windows 7 who and when use(d) a certain share?

    - by John Thomas
    We have a workstation using Win7 on a LAN with a domain. On that workstation we set up some network shares. Can we find who used (user name and/or computer name) and when the shares? Note that we know about Computer Management System Tools Shared Folders Open Files. We don't want to see so much real-time who's using the shares but we are interested more in a logging solution, ideally interpreting / using the data from Win7's Event Viewer.

  • Configuring linux server firewall to allow access from a certain range of IP addresses

    - by eggman20
    Hi Guys, I'm new to linux server. I'm currently trying to get an Ubuntu 10.10 server up and running for the first time and I'm using Webmin for administration. I'm stuck on the setting up the firewall. What I need to do is to ONLY allow a range of IPs (e.g 128.171.21.1 - 128.171.21.100) to access the HTTP server and Webmin. I've seen a lot of tutorials but none of them fits what I needed. Thanks in advance!

  • Why would my 15" MacBook Pro suddenly ask me to Hard Quit while I was in a browser?

    - by flathead27ford
    I was in Firefox looking at a search I had performed in eBay and all of a sudden, the screen grayed out starting from the top down. In the middle of the screen was a box with about 5 different languages saying I had to hard quit my computer. I tried other keys on my computer and nothing was working so I hard quit and restarted. Can anyone tell me why this happened? Cheers, Kyle

  • Isolating Apache virtualhosts from the rest of the system

    - by JesperB
    I am setting up a web server that will host a number of different web sites as Apache VirtualHosts, each of these will have the possibility to run scripts (primarily PHP, possiblu others). My question is how I isolate each of these VirtualHosts from eachother and from the rest of the system? I don't want e.g. website X to read the configuration of website Y or any of the server's "private" files. At the moment I have set up the VirtualHosts with FastCGI, PHP and SUExec as described here (http://x10hosting.com/forums/vps-tutorials/148894-debian-apache-2-2-fastcgi-php-5-suexec-easy-way.html), but the SUExec only prevents users from editing/executing files other than their own - the users can still read sensitive information such as config files. I have thought about removing the UNIX global read permission for all files on the server, as this would fix the above problem, but I'm not sure if I can safely do this without disrupting the server function. I also looked into using chroot, but it seems that this can only be done on a per-server basis, and not on a per-virtual-host basis. I'm looking for any suggestions that will isolate my VirtualHosts from the rest of the system. PS I'm running Ubuntu 12.04 server

  • Deploying Office 2013 via GPO

    - by NickC
    Looking at potential ways to deploy Office 2013 via GPO. First and most obvious way is to run a startup script which calls the Office 2013 setup.exe. Problem here is what happens after it is installed, will that startup script keep re-installing the product every time the machine boots? Another potential way is to install each Office component separately using the multitude of .msi files which are present, would that work and provide the same thing as a full install of Office? There is actually twenty three separate .msi files. What about officemui.msi is that a wrapper which contains calls to all of the other office components.

  • Restrict Computer or Users from Internet but allow access to intranet and Windows Update / ePO?

    - by MoSiAc
    So this may be impossible but I've been asked to try and find something about it. So far nothing I have found is possible. I need to restrict specific machines or user accounts from regular Internet access but let them have access to the intranet portion of our network. I do not have Active Directory control, nor does anyone at my local workplace (corporate control in a different state). I have tried going through IPsec and doing this per local machine, but that system seems to have been removed from the images that are installed on these machines so that is out. So far the only other option I can think of is assigning the machines a specific ip address and removing their gateway access. This would probably work but the machines need to be able to receive updates that are being pushed to them through ePO and LanDesk. I would really like to do this on the user level because then if I need to do tech work to the machine and need internet access I can get to it but a "special" user could login and not be able to get into anything.

  • TCP: Treason uncloaked!

    - by hurikhan77
    On one linux server (Gentoo hardened), we are experiencing bursts of the following messages in dmesg from time to time: TCP: Treason uncloaked! Peer xx.xx.xxx.xxx:65039/80 shrinks window 4094157295:4094160199. Repaired. Is there anything we should take care of or is this normal?

  • Can someone access my locally ran website even if I haven't specified any port forwarding?

    - by user701510
    I am using Xampp so I can test my web application directly on my own computer. I am concerned that someone can access my Xampp site since I am still connected to the internet. However, I have NOT explicitly enabled any port forwarding with respect to my Xampp site in my router firewall settings. Furthermore, I am using a dynamic ip address. Given the factors already stated, can someone from outside my local network still access my locally ran website?

  • Locking down firmware to keep stolen laptop from being formatted?

    - by Matt Ridge
    On the Mac laptops there are ways through the terminal to lock down the computer so that if someone tries to format the computer they won't be able to do it without the password. This way locks down the firmware. Is there a universal way to do the same thing on a PC? I know there are brands out there such as Samsung, Dell, etc that utilize different fimware types, and in turn will mean that their firmware will be locked down differently. That being said is there a "command code" that will allow you to lock the firmware to keep theives from formatting the hard drive and wiping out your data? I know a person who has time, and knowledge can get any password, and hopefully the person is smart enough to use another password to lock down the firmware, but that's not what I'm asking. I'm asking if it's possible, and if so how? Does the standard PC user require a 3rd party app, or can it be done through the command line? Or Terminal if you are on Linux?

    - by slayernoah
    I have an application installed in /etc/mydir. I have executed the following to remove the ability for users to execute this program. chown root:group1 /etc/mydir -R chmod 700 /etc/mydir -R I created a new user and logged in as this user. The new user was not added to group1 However, I was able to execute this program by just typing the program name. How can I stop users being able to run this using chmod and chown. Please let me know. PS. the new users cannot cd into /etc/mydir but they can still execute using the program name.

  • Any FTP clients for Mac OS X that support upload via temporary filename?

    - by Chris582
    Hi, does anybody know of a FTP client (for Mac OS X) that supports uploading to a temporary filename? When overwriting a file on the server, most FTP clients first empty the file and then proceed to upload new content. (Which is how FTP is supposed to work, so everything is fine.) However, what I would like to see is that the FTP client uploads content to a temporary file and once all the content is on the server, replaces original file. This is good feature, because existing file is upgraded almost instantaneously; otherwise, it would be "broken" while the upload is still in progress. On Windows, this feature is available in WinSCP, but I have not found any options for Mac, so far. Any recommendations?

  • Chrome - Why am I automatically authenticated to a web app even after clearing browser cookies?

    - by Howiecamp
    I am accessing a web application using Chrome. If I sign out of the app and clear all Chrome history/cookies/etc (even Flash cookies which are now handled by Chrome in the same Clear History area) and then re-access the site, I am automatically logged in without being prompted for credentials. I then launched Chrome in Incognito mode and was able to reproduce the same behavior. However, the I was prompted upon the first logon while in Incognito mode. The web application behaves as expected in Internet Explorer 10. Some info about the application: It's a Sharepoint site using NTLM authentication The credentials are Active Directory-based, as the username is domain\username My connection is over the Internet and there is no AD relationship between my local Windows account, my Windows PC. In other words I (meaning my locally logged on user and my PC) are not in any way part of their AD domain. The site is running SSL on port 443 Why might Chrome be automatically authenticating me?
