• Hidden Periodic Screenshots on a corporate workstation?

  - by ssxuser80

  Can anyone recommend something that allows us to take hidden periodic screenshots of a workstation? We have a user who we believe is abusing his computer privileges. We have our suspicions that he may be playing games, etc. We need to monitor his screen without him being aware of it. Currently, the IT Department here is using Dameware Mini Remote Control to view his login sessions. But there isn't an option to set up automatic periodic screenshots. I'm hoping to find a tool that has this option and can be centrally managed as well. Thank you for your time. Any help would be greatly appreciated.

• Can I use static routing to allow me to use my public IP from my LAN?

  - by jnm2

  I would like to be able to use the same hostname to connect to my computer from my phone whether I'm at home or away. Currently I have to maintain duplicate entries for remote desktop, for instance. My router doesn't seem to have a NAT loopback option. I have two routers in fact, a cable modem which goes straight to my main router which does wireless. I can add to the static routing tables on each. Can I use this to loopback the public IP or do I need different routers?

• Opening ports with IPTables not working - Ubuntu

  - by user41416

  So, I have these rules set in iptables: # iptables -L Chain INPUT (policy ACCEPT) target prot opt source destination ACCEPT tcp -- anywhere anywhere tcp dpts:6850:6999 ACCEPT udp -- anywhere anywhere udp dpts:6850:6999 ACCEPT tcp -- anywhere anywhere tcp dpt:6881 Chain FORWARD (policy ACCEPT) target prot opt source destination Chain OUTPUT (policy ACCEPT) target prot opt source destination Although, the ports are not open :/ here is a telnet attempt: # telnet localhost 6999 Trying 127.0.0.1... telnet: Unable to connect to remote host: Connection refused Any idea why this is happening? Do I need to reboot or do someone to make the changes permanent? Last time I rebooted the rules disappeared from iptables :/

• SSL Certificate only works when session active in Server 2008

  - by CodeMonkey1

  I have a web app that uses an installed certificate to send a web request to a 3rd party web service. This has worked for a long time on Windows Server 2003, but just recently we found a problem with it on 2008 installations. When logged into the server as the same user the App Pool uses, either locally or via remote desktop, the web app and it's secure 3rd party request works fine. However, when there are no user sessions open, the 3rd party request fails, as if the certificate were not attached to the web request. Any ideas?

• SFTP not working, but SSH is

  - by Dan

  I've had a server running CentOS for a few months now. A few days ago, I stopped being able to connect to it over SFTP. I've tried from multiple computers, OSes, clients, and internet connections. I can SSH in just fine, though. For example, Nautilus gives me this: Error: DBus error org.freedesktop.DBus.Error.NoReply: Did not receive a reply. Possible causes include: the remote application did not send a reply, the message bus security policy blocked the reply, the reply timeout expired, or the network connection was broken. Please select another viewer and try again. I was under the impression that SFTP was just pure SSH, and if one worked, the other would, and vice-versa. Clearly that's not the case, though. What could I have done wrong?

• Safe to use high port numbers? (re: obscuring web services)

  - by sofakng

  I have a small home network and I'm trying to balance the need for security versus convenience. The safest way to secure internal web servers is to only connect using VPNs but this seems overkill to protect a DVRs remote web interface (for example). As a compromise, would it be better to use very large ports numbers? (eg. five digits up to 65531) I've read that port scanners typically only scan the first 10,000 ports so using very high port numbers is a bit more secure. Is this true? Are there better ways to protect web servers? (ie. web guis for applications)

• how can i disable safe mode for php on web server?

  - by user1767434

  I am using wkhtmltopdf for making a pdf of a page. My code executes the shell to run a command using this wkhtmltopdf library. Everything works fine in my wamp server but when the code runs on my web-server it does not work and gives the following error: Warning: shell_exec() has been disabled for security reasons in /home/pssptech/public_html/.../cert.php on line 272 I think that the php is running on safe mode on the server that's why the shell execution is disabled. But the main problem is I am unable to find the php.ini file on my remote web-server. Can you tell me where can I find the config file so that I can disable the safe mode? Thanks in advance.

• Laptop connectd to 2 VPNs (1st for Internet over WiFi, 2nd to access shared folders on another network) is failing to route traffic over 2nd VPN

  - by Triynko

  I set up a VPN on Windows Server 2008 through its routing and remote access services. I connected to the VPN, and configured the client to allow for split tunneling (Internet traffic goes to my default gateway, and traffic directed to the VPN server goes through the VPN gateway). I had to adjust the routing table, adding an entry to ensure traffic to my VPN server goes through the tunnel by running the command "route add [VPN.IP] mask 255.255.255.255 [VPN.GATEWAY.IP] IF [VPN_INTERFACE_#]". Adding the correct route makes everything work flawlessly on all my machines, except for one. The problematic machine is a laptop that's not directly connected to a network. It connects to WiFi, and then connects to a VPN to obtain internet access. Finally, it connects to the target VPN server for file sharing. The "route add" trick doesn't work for that laptop, I'm assuming because it's connected to two VPNs, and I'm getting the routing wrong. Can anyone familiar with routing explain what routes I may need to add?

• When one DC crashes, TFS 2012 stops working

  - by blizz

  We have two Windows 2008 domain controllers. We installed the second DC only a few months ago. We also have a TFS 2012 server on the network. Today, when the older DC crashed, TFS stopped working completely. Local users received messages such as "You are not authorized to access ServerName\Collection". Remote users received messages such as "The server was used in your last session, but it might be offline or unreachable". So my question is, why did TFS not use the second, newer DC instead of just crashing along with the first DC?

• Access server by hostname without domain

  - by projectshave

  I want to access services on other machines on my home network with just their hostname. In every browser, "http://machine" fails, but adding a period in "http://machine./" works. Is there a way to avoid adding that extra period? My setup is a router with DD-WRT w/ DNSmasq turned on, Win7 machines and several Ubuntu VMs. nslookup works fine with just hostname. Remote desktop works, but TightVNC needs the extra period. ssh needs the period. As I said, all my browsers need the extra period. I'd prefer a solution that doesn't require manually maintaining the hosts file. Thanks.

  I am currently in a situation where the system time of my windows machine differs 6 hours from the actual local time. I tried chaning the system time of my windows machine 6 hours back to match the actual local time. The issue is, when the system time is changed, Exchange stops working as it wont start anymore. When i change the time back Exchange works again. Here is the error that it shows when im trying to open the management console after changing the system time. The Follwing error occured while attempting to connect to the specified server "servername". The attempt to connect to http://servername/PowerShell using "Kerberos" authentication failed: Connecting to remote server failed with the following error message: Access is denied.

• How to install a mmc certificate on Windows?

  - by Alex

  I am not familiar with Windows very much, and I have trouble installing a MMC certificate. I am following this description to use MMC to create a certificate, but I cannot complete the step labeled ' Install or view the certificates under:'. There is nothing unter 'ConsoleRoot' - 'Certificates (Local Computer)' - 'Personal', and when I try to find the certificate I cannot find it. There is another page with nice screenshots, which works until step 9 when I am about to choose the certificate file. I do not know where this file is been created, if at all. How can I create/install/import this certificate? I require this in order to use the powershell Enter-PSSession from a remote machine...

• Store system passwords with easy and secure access

  - by CodeShining

  I'm having to handle several VPS/services and I always set passwords to be different and random. What kind of storage do you suggest to keep these passwords safe and let me access them easily? These passwords are used for services like databases, webserver user and so on that run customers' services, so it's really important to keep them in a safe place and strong. I'm actually storing them in a google drive spreadsheet file, describing user, password, role, service. Do you know of better solutions? I'd like to keep them on a remote service to make sure I don't have to make backup copies (in case my hdd would fail somehow). I do work on *nix platforms (so windows specific solutions are not a choice here).

• How to add network printer remotely without knowing the IP?

  - by Steve

  Assume your friend from over 100km away asked you to add a network printer to his computer since you're so tech savvy. How would you add network printer remotely in this case? You would need: 0. Remote connection to your friend's computer 1. Printer IP and brand/model names 2. Respective drivers downloaded either from manufacturer's website or Windows Update driver Question is, how would you find out the IP address of the printer without bothering your friend too much with technical steps? Since your friend isn't as tech savvy as you - they wouldn't know which buttons to press to get IP address.

• syslog facilities

  - by user65971

  Hi, I have an application (in java) running in a windows PC and I want to send logging messages to a syslog server running in a linux box somewhere in the network. The problem I have is, that it is not clear to me what should I use as facility in this case. I.e. can I (/should I) send the logging info as one of LOCAL0-LOCAL7? Or are they not supposed to be used by remote applications? It is not clear to me if they are usable or not. Should I use USER instead? Could anyone help me on this please? Thank you

• how to actually install PHP etc on a windows 2003 server

  - by user1624421

  We're just purchasing a dedicated windows 2003 server (in fact I think it's a VPS) How do we actually go about installing software on to it? Simply searching for "installing PHP5 on windows server" just produces material about installing it as if one had access to the computer with a keyboard and mouse. Am I being thick? I've had experience managing a linux server before but that had everything pre-configured and we accessed it via Web Hosting Manager. I don't get the actual concept of connecting to a remote PC and...downloading files? If there's any good books available please point me in the right direction.

• Network connectivity issue

  - by kubiej21

  I am a novice cisco user and I am trying to investigate as to why one of our connections went down. We have a fiber network ring that is operating just fine. Connected to this ring via ethernet, is a lone 3560. This connection has worked flawlessly for the past year and a half. This morning, I noticed that I could not connect to that remote switch. I checked the configurations on both switches, and nothing has changed (as I expected). In the field, the port lights were flashing, indicating that some sort of communication is occurring. There is only 1 ethernet cable that has been run between these two locations, so testing an alternate path is not possible. What else can I do to fix this connection?

• a safer no password sudo?

  - by Stacia

  Ok, here's my problem - Please don't yell at me for being insecure! :) This is on my host machine. I'm the only one using it so it's fairly safe, but I have a very complex password that is hard to type over and over. I use the console for moving files around and executing arbitrary commands a LOT, and I switch terminals, so sudo remembering for the console isn't enough (AND I still have to type in my terrible password at least once!) In the past I have used the NOPASSWD trick in sudoers but I've decided to be more secure. Is there any sort of compromise besides allowing no password access to certain apps? (which can still be insecure) Something that will stop malware and remote logins from sudo rm -rf /-ing me, but in my terminals I can type happily away? Can I have this per terminal, perhaps, so just random commands won't make it through? I've tried running the terminal emulations as sudo, but that puts me as root.

• Disable address bar in Internet Explorer 9

  - by token

  I'm trying to disable the address bar in IE9. I've done a significant amount of searching on this and just can't seem to find a way to make it happen. A lot of web resources discuss how to do it in IE8, but not IE9. The reason you might ask? I have an application being hosted in a remote desktop farm that links to web pages outside of the application into Internet Explorer. I need to ensure users are limited to just going to the pages the program pushes them to. I realize I could use a proxy server to limit where they can go, but I'm trying to find a really simple way to just disable the address bar instead. I can't use Kiosk mode because it puts the browser into full screen mode. This won't work for my situation as I need to give users what appears to be a regular browsing experience without an address bar.

• How can I solve Windows PPTP VPN issues?

  - by Robin M

  I'm having persistent problems with Windows PPTP VPN connections. The VPN appears up whilst the tunnel won't transfer traffic (ping to a remote IP within the VPN works for a while, and then fails). The client receives routing information via DHCP. When the connection fails, the routing table is still correct so I don't think it's a routing problem. My internet connection is via an ADSL2 line. There's software to deal with PPTP problems, like TunnelRat, but I don't want to install v1.1 of the .NET framework and I'd rather get to the bottom of the problem (I have multiple VPN connections and some are more unreliable than others). What can I do to get to the bottom of this? Alternatively, what can I do to keep the connection alive?

• How can you import a root certificate to a machine level store in Windows 7

  - by ReluctantAdmin01

  I have a service (Running as local system) that uses an SSL connection. Currently this connection fails because the remote host used a private CA to sign it's certificate. For previous operating systems, I used to use the certificate manager to import the CA cert into the local machine's Trusted Root certificates store. Though I can do the steps with a windows 7 machine, it seems after a reboot that the imported certificates are gone. Here are the steps I'm doing in Windows 7: Open mmc Add Certificates Snap-in for Local Machine Navigate to Third-Party Root Certification Authorities/Certificates Import Root CA Cert. The certificate seems to work fine, using internet explorer or the service to test the SSL connection works, but after a reboot it seems like the change is reverted.

• Can I run Win7 virtualized for my HTPC?

  - by Daniel Schaffer

  I'm currently running Vista for my HTPC, and am planning on upgrading to Win7 soon. However, I've been considering installing it as a VM so that I can run Windows Server 2008 and/or Windows Home Server. The single requirement is that the HTPC must boot up to Windows Media Center with absolutely no user intervention. I need to be able to hit the power button have it go. I've got this working currently, so I don't need to keep a keyboard or mouse plugged in - all I use is my remote. If possible, I'd love to be able to do these other things: Use Win2k8 Server as a VM host for Win7 Pro and WHS. This also lets me run IIS7 for doing ASP.NET development Use WHS for all the wonderful things it does for a home network Are either of the two optional things possible while meeting the WMC requirement?
