• FTP error when doing file transfer

  - by Ernie

  I'm running vsftpd version 3.0.2 over FTPeS, and I'm having a bit of trouble with file transfers. It seems to work fine when I'm on the LAN, but not from an external IP address. I have the control port and data ports open on my server's software firewall and my router's firewall. When I'm using the service from an external IP address, it seems like sometimes a file transfer will complete, but it times out and I always get the client error: "426 Failure writing network stream". I've tried several clients. I'm thinking there is some sort of data sabotage either at the router or some server policy; maybe because I'm using passive ftp? Suggestions?

• setup advanced filtering and access restrictions on dd-wrt using iptables

  - by Nova deViator

  I have a linksys WRT54GL router with a DD-WRT installed and I want to setup some advanced filtering that seem to not be available through "Access restrictions" web gui option. I guess I would be using IPTABLES then. I have ssh access to router and can run iptables, but I'm not so experienced with iptables. So here are my needs: my policy would be deny all first and then allow exceptions allow all http (port 80) access to WAN through wireless allow all other traffic only to PCs with specific MAC addresses allow internet access to PC with specific MAC address according to schedule (let's say everyday between 18:00-21:00) is this possible to setup with IPtables? could somebody help me a bit with it? or should go and RTFM?

• How to have a soft-real-time process in presense of heavily swapping IO-intensive background load?

  - by Vi

  schedtool: PID 32301: PRIO 4, POLICY R: SCHED_RR , NICE -20, AFFINITY 0xf ionice: realtime: prio 4 But the music is stumbling anyway. Background load is low prio (SCHED_IDLEPRIO, idle ionice), but uses a lot of memory (more than is physically available) and does a lot of IO and calculations. Latencytop shows about 1500ms for: Following symlink Writing buffer to disk (sync) Page fault Writing a page to disk both for the bg load and for unrelated processes. Load average is 10 and counting. Why cannot it allocate, for example, 200MHZ of one of the cores and 32M of memory and not less than once per second opportunity for IO for mplayer to make it happy while continuing calculations on the background? Or: why it cannot leave background task and swap loving each other but keeping the rest of the system as if there were no background load? How to have RT processes AND heavy bg load simultaneously (without of virtual machines)?

• Schedule of Password Expiration to a specific time

  - by elcool

  Is there a way in Windows Server 2003 or 2008 and in Active Directory, to specify in a policy that when a users password expires that day, to have it expire at a certain time, say 4:00am. The issue came up, because the expiration occurs during the middle of the working day, say 9:00am. Then when a user is already logged into Windows in the network, and using different applications, those will start behaving wrongly because of authentication. They have to log out and log back in, in order for Windows to ask for the new password. So, if when they log in early in the morning it would ask for the new password, then they won't have to log back out during the working day. One of the AD Admins said: "Have them check if their password will expire before starting the day".. but really, who does that? And I don't have access to an AD to check these types of policies. So, is this possible?

• Install Office software on a standard user account automatically.

  - by Earls

  If I know the Administrator account name and password on a Windows 7 computer, would it be possible to create an Office 2010 install CD that would "silently" install Office 2010 on a standard user account which does not have installation privileges. As in, the group policy "always install with elevated privileges" is in effect for the user. Some way to built the admin account privileges into the office installer? VBS Script? CMD? Understand, the laptops are in the field, the end user doesn't have the admin password and can't have the admin password. Thanks.

• How to manage a large email delivery volume from a Email Marketing App ?

  - by Newtonx

  We provide Email Marketing service through our online Application. We have about 30 customers. And each one has it's own mailling list (5k to 100k emails each). What we really want is to distribute email's delivery between 2 or more servers. I was wondering What kind of aproach/solutions MailChimp , Constant Contact uses to provide a great service ? use many servers ? many IPs ? Our spam policy suspends ANY user/customer that gets 10% bounced . We currently rotate our outgoing Mail Ip once deliveries limit per remote host is reached. Is it the best approach/solution ?

• restrict windows remote desktop

  - by radioactive21

  Is there any way to prevent users from launching and using remote desktop and to restrict it to only local admins or domain admins? The reason being is that we do not want users to remote desktop home, but at the same time we want it to be available to certain users like administrators or power users. Ideally there is a group policy that can be set to groups or users who have access to the remote desktop application from their machine. Clarifications: I need the machine to be able to still have remote desktop work, just only with a specific user or group. The point is that we allow certain users to use remote desktop and others to not have access to it. There are machines where there are multiple users, so we cant just block a whole machine or by IP. This needs to be done per a user account or login.

• how to remotely setup powershell to accept Enter-PSSession

  - by user1399195

  I have some computers I'm trying to remotely execute powershell commands but I'm running into some snags. For one thing, the computers do not have Enable-PSRemoting enabled so I am unable to simply Enter-PSSession. I tried to run a powershell script through psexec but I have yet to Set-Execution Policy on the machine. My thoughts were to execute a powershell logon script that accomplished this but before I tried this I was going to see if there were any other methods to enable-psremoting on a machine. Thanks in advance!

• What is the default value for Empty Temporary Internet Files when browser is closed in IE8?

  - by schellack

  We have four different machines that all have "Empty Temporary Internet Files when browser is closed" set to true (checked) in IE8's Internet Options (located under the Security section in the Advanced tab). No one remembers checking that checkbox to turn on the setting. What is the default value supposed to be? I'm specifically interested in Windows 7 and Windows XP. I have run rsop.msc on one of the corporate machines—3 of the 4 are members of a corporate network/domain—and see this under User Configuration, which makes the current scenario seem even stranger: The Local Group Policy Editor (gpedit.msc) also shows the Configure Delete Browsing History on exit setting to be Not configured (under Computer ConfigurationAdministrative TemplatesWindows ComponentsInternet ExplorerDelete Browsing History).

• Prevalence of WMI enabled in real Windows Server networks

  - by TripleAntigen

  Hi I would like to get opinions from systems administrators, on how common it is that WMI functionality is actually enabled in corporate networks. I am writing an enterprise network application that could benefit from the features of WMI, but I noted after creating a virtual network based on Server 2008 R2, that WMI seems to be disabled by default. Do systems admins in practical corporate networks enable WMI? Or is it usually disabled for security purposes? What is it used for if it is enabled? Thanks for any advice! MORE INFO: I should have said, I really need to be able to query the workstations but I understand that by default the WMI ports on Win7 and XP firewalls (at least) are disallowed, so do you use some sort of group policy or other method to leave a hole open for WMI on the workstations? Or is just the servers that are of interest? Thanks for the responses!!

• How to determine the source for wakeup in hibernate

  - by Erik

  I have a big problem with my home theater PC that runs Windows 7 64Bit. Normally, I send that PC to hibernate every evening, but from time to time, it keeps waking up for no obvious reason, and stays on until I realize, which is sometimes half a day later :( I have already checked for Windows update, which is not set to automatical, since I prefer installing updates manually. When I look in the system event log, there is an entry called "Power Troubleshooter" which tells me that my system was reactivated at a specific time, but it also says: Source = Unknown, which is the most annoying part. So how can I actually figure out, which process reactivates the PC? Is it possible to set a group policy which forbidds applications or services from scheduling tasks that allow waking up from hibernate at all?

• Understanding connection tracking in iptables

  - by Matt

  I'm after some clarification of the state/connection tracking in iptables. What is the difference between these rules? iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT iptables -A FORWARD -m conntrack --ctstate ESTABLISHED,RELATED -j ACCEPT Is connection tracking turned on when a packet is first matched containing -m state --state BLA , or is connection tracking always on? Can/Should connection state be used for fast matching like below? e.g. suppose this is some sort of router/firewall (no nat). # Default DROP policy iptables -P INPUT DROP iptables -P OUTPUT DROP iptables -P FORWARD DROP # Drop invalid iptables -A FORWARD -m state --state INVALID -j DROP # Accept established,related connections iptables -A FORWARD -m state --state ESTABLISHED,RELATED -j ACCEPT # Allow ssh through, track connection iptables -A FORWARD -p tcp --syn --dport 22 -m state --state NEW -j ACCEPT

• Only ONE Outlook 2010 installation "Cannot connect to Exchange server" when setting up new profile.

  - by Johnny PDEX

  Exchange 2010, one-server installation (small production, I know not best practice) OWA Connectivity has been confirmed, Autodiscover is configured and working properly for EVERY other installation. Other user accounts tested on problem Outlook, none can connect. Windows Firewall is pre-configured by Group Policy, only modifications being related to remote management. Firewall has also been disabled during diagnostic period. Network discovery and file sharing is enabled on workstation as well. Windows 7 Professional, latest updates installed. Driving me nuts. Help, serverfault?

• Change Win7 taskbar position (overriding GPO, Registry Editor, Admin. Rights)

  - by diegocavazos53

  I run the computer center of my Faculty and the problem is that users manage to change the Win7 taskbar position. I don't really know how they do this as far as I have applied many group policies that are specific to the taskbar (like locking it). I have also disallowed users from entering new registry keys or executing the command prompt (or employing scripts). They have regular user rights and many Win7 tweaking programs need administrator rights to make changes to the GUI. So in other words, the taskbar is locked, there is a policy that sets its position to the lower part of the screen, users can't see the control panel, add registry keys, use the command prompt and don't have admin. rights. How do they keep moving the taskbar position to the upper part of the screen? Any ideas would be greatly appreciated. Thank you.

• How to restore default iPod playlists on Amarok?

  - by obvio171

  I wanted to "reset" the collection on my iPod and ended up accidentally deleting, through Amarok, all the playlists, including the default ones like "Most Played" and "Highest Rated". Since these are dynamic playlists with a special meaning for iPod, I don't think creating new, normal playlists with the same name will bring their special behavior back. How do I restore them with the same dynamic functionality? Is there a way to do that on Amarok? Rhythmbox? GTKPod? Command line? P.S.: not entirely sure what the policy about iPod questions are, but this one in particular seems to me to be very computer-related because, although it's about interfacing with a device, everything has to be done on my computer, using standard PC libraries/programs, etc. If it's still off-topic, please point me to where I could post it.

• HTTPS vs. VPN for communication between business partners?

  - by Andrew H

  A business partner has asked to set up a site-to-site VPN just so that a few servers can communicate with each other over HTTPS. I'm convinced this isn't necessary, or even desirable. To be fair it must be part of a wider policy, potentially even a legal requirement. However I'd like to convince them to simply offer an IP to us (and us only) and a port of their choosing for HTTPS. Has anyone had a similar experience, or had to come up with a cast-iron argument against a VPN? Allow me to expand a little - we have a web service that initiates a connection to the partner's corresponding service using an encrypted HTTP connection. The connection uses a client certificate to authenticate. The connection is firewalled so only our IPs can contact the service. So why is a VPN necessary?

• How do I configure the Google Chrome / Chromium address bar to perform a search instead of trying to access a file on the local file system?

  - by Daniel Kauffman

  How do I configure the Google Chrome / Chromium address bar to perform a search instead of trying to access a file on the local file system? I would like to be able to enter a file name in the address bar and to see Google search results for that file name similar to what I would see if I searched for the file name using something like https://www.google.com/#q=/path/to/interesting/file I am able to disable the file scheme using either of the following policy settings: "DisabledSchemes": ["file"], Which has been deprecated in favor of: "URLBlacklist": ["file://"], But in either case Google Chrome / Chromium continues to auto-detect that a file name was entered, automatically prepends the file scheme to the file name, and then reports that the webpage is blocked.

• Member of local Administrators group cannot elevate

  - by fixme

  Hi We have just installed the first Windows 7 (professional) workstation in our domain. Its primary user has been added to the local (computer's) Administrators group (computername\Administrators). Still, whenever elevation is needed, his credentials are not accepted, and he is never allowed to act as an administrator. For example, he cannot write a file to C:\ (not that he needs to, but it illustrates the problem). Putting him in the domain's Administrators group doesn't help either (anyway we'd rather not do that). I suspect that he may be the victim of some policy that controls elevation, but can't seem to find it. Can anyone shed some light?

• HP 4530s: Fan is Always On even When Laptop/CPU is Idle

  - by tolitius

  Just bought an HP 4530s from newegg. Laptop is great, but.. The FAN is always on. I did some googling, found it is a known problem, but no easily googlable solution. Tried to: Update BIOS to the latest Disable "CPU fan always on when plugged in" BIOS setting Installed Windows 7 Home (came with), Live CDed Ubuntu, Windows XP Spent 2 hours with horrible HP support Some other things that I can't already recall = spent too much time on it Laptop is not refundable (learned it the hard way, after the fact, by looking at the NEWEGG clever policy that is hidden in "details") I would really appreciate a workable solution / workaround / hack. The laptop is for my friend who will most likely be running Windows XP/7.

• Moving to an outside Exchange provider - How to create new Outlook profile on multiple PCs?

  - by imagodei

  Following an acquisition we are switching from our local Exchange to an outside provider. I need to change account settings / create new profile so that users are able to access their new mailbox, and I hate the idea of doing it manually on every single client. I have tried quick and dirty solution with copying profile information from Registry on one computer to the other, hoping that I could fix user info later. Quite obviously, this didn't work: Outlook recognized the profile, I could select it at the application startup, but there the fun ends - the profile was corrupt. I couldn't change settings in Mail settings on Control panel, either. Didn't find any Group policy solution. Is there any application, script or other solution, that would help me save time commuting from one PC to the other and typing the same info over and over again?

• How do I turn autocomplete on for a server running Windows Server 2008?

  - by user16011

  My end users are not able to use autocomplete when they use a web application hosted on a particular server. Autocomplete is usually a client-side setting. My users can use autocomplete when they are on other websites so I think it is a server setting in this case. How do I turn autocomplete on for a server running Windows Server 2008? Is this a setting in IIS, a registry setting, a group policy setting, or something else? Thanks in advance.

• DNS works only with ip but does not work with NS CentOS + Bind9

  - by Borislav Yordanov

  I am having a headache with DNS. Lets say my public IP is 1.2.3.4, my local IP is 192.168.0.10 and my domain is example.com I am running CentOS on a virtual machine (Parallels Desktop for Mac) with a LAN card reserved for it, so it gets Ip directly from the router.

• What are the default/recommendet access rights for %ALLUSERSPROFILE%?

  - by RED SOFT ADAIR-StefanWoe

  We have a Windows application that reads and writes some data for all users. We place it at %ALLUSERSPROFILE%\OurProgram*.* We now encounter a few cases in larger companies, where users do not have write permission to %ALLUSERSPROFILE%. Most of these cases are running Windows 7. The problem does not occur on a normal desktop installation of Windows 7 though. What is the recommended policy for this location? I have not found any "official" information about this. Is there a different location where all users have write permission?
