• Iptables rules make communication so slow

  - by mmc18

  When I have send a request to an application running on a machine which following firewall rules are applied, it waits so long. When I have deactivated the iptables rule, it responses immediately. What makes communication so slow? -A INPUT -m state --state RELATED,ESTABLISHED -j ACCEPT -A INPUT -p tcp -m tcp --dport 22 -j ACCEPT -A INPUT -p esp -j ACCEPT -A INPUT -i ppp+ -j ACCEPT -A INPUT -p udp -m udp --dport 500 -j ACCEPT -A INPUT -p udp -m udp --dport 4500 -j ACCEPT -A INPUT -p udp -m udp --dport 1701 -j ACCEPT -A INPUT -i lo -j ACCEPT -A INPUT -i lo -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT -A INPUT -m limit --limit 5/min -j LOG --log-prefix "iptables denied: " --log-level 7 -A FORWARD -i ppp+ -m state --state NEW,RELATED,ESTABLISHED -j ACCEPT

• powershell indentation

  - by Steve B

  I'm writing a large script that deploys an application. This script is based on several nested functions call. Is there any way to "ident" the output based on the depth ? For example, I have : function myFn() { Write-Host "Start of myfn" myFnNested() Write-Host "End of myfn" } function myFnNested() { Write-Host "Start of myFnNested" Write-Host "End of myFnNested" } Write-Host "Start of myscript" Write-Host "End of myscript" The output of the script will be : Start of myscript Start of myfn Start of myfnNested End of myFnNested End of myFn End of myscript What I want to achieve is this output : Start of myscript Start of myfn Start of myfnNested End of myFnNested End of myFn End of myscript As I don't want to hardly code the number of spaces (since I does not know the depth level in complex script), how can I simply reach my goal ? Maybe something like this ? function myFn() { Indent() Write-Host "Start of myfn" myFnNested() Write-Host "End of myfn" UnIndent() } function myFnNested() { Indent() Write-Host "Start of myFnNested" Write-Host "End of myFnNested" UnIndent() } Write-Host "Start of myscript" Write-Host "End of myscript"

• ZFS Configuration advice

  - by rbarrette

  I need some advice on configuring ZFS. Here is what I have: Physical Disks: 4x 3 TB 2x 2 TB 2x 1 TB What is the best configuration for my Vdevs and storage pool. I want to maximaze space but still maintain redundancy. Should I just get 2 more 3TB's and just create 2x 3-3TB raid2z storage pools? Create a 1x 4-3TB raidz2 vdev? Can I put redundancy at the pool level and create individual vdevs for each drive and then add 2x 1TB+2TB striped vdevs to keep all vdevs the same size. Keep in mind I do need to migrate data from the smaller drives and am planning on adding more 3tb drives later on. What do you think?

• Where does traffic shaping typically take place?

  - by eekmeter

  As part of upgrading our network infrastructure we are looking to traffic shape our bandwidth since we only have about 3Mb down / 1 Mb up. We're looking to prioritize it so that web browsing gets priority and in the future some VOIP might be added in as well. Internal LAN traffic doesn't need to be controlled just our outbound connection. I've been looking at Cisco hardware and it seems that several of their products do shaping at the core switch, firewall, and router level. I'm wondering where does shaping normally take place? Is it normally done at the router, core switch, or firewall?

• High CPU Steal percentage on Amazon EC2 Instance

  - by Aditya Patawari

  I am experiencing high CPU steal percentage in a Amazon EC2 large instance. I know it means that my virtual CPU is waiting on the real CPU of the machine for time. My question is that what can I do to reduce this percentage and get maximum out of the CPU? Steal percentage is consistently at 20%. System load crosses 10 when this happens. I have checked memory and network and I am sure that they are not the bottleneck. Is that normal for such environment? Also are there any system level optimization techniques for reducing steal percentage form the virtual instance? avg-cpu: %user %nice %system %iowait %steal %idle 52.38 0.00 8.23 0.00 21.21 18.18

• Replicate a big, dense Windows volume over a WAN -- too big for DFS-R

  - by Jesse

  I've got a server with a LOT of small files -- many millions files, and over 1.5 TB of data. I need a decent backup strategy. Any filesystem-based backup takes too long -- just enumerating which files need to be copied takes a day. Acronis can do a disk image in 24 hours, but fails when it tries to do a differential backup the next day. DFS-R won't replicate a volume with this many files. I'm starting to look at Double Take, which seems to be able to do continuous replication. Are there other solutions that can do continuous replication at a block or sector level -- not file-by-file over a WAN?

• How to troubleshoot Application Popup issues 0XC0000142 and 0XC000009a

  - by DotDot

  I am running randomly into 1 of these popups when our application runs. The machines range from 8GB/8Core to 24GB/24Core and run Windows Server 2008 R2. The application is a bunch of perl scripts and exe's that are expected to utilitize the server well. The process tree can be quite deep (5-6 child levels) and quite broad (60-70 level 1 processes). We hit this issues every 1% run on random machines. The application stalls on popup, unless someone clicks the damn button. The event log reads as cmd.exe - "Failed to initialize app. Click OK to close app" How could I reliably repro these issues?

• Programmatically change height of the window more than the height of the screen in Mac OS X

  - by nezlooy

  Respected low-level users of Mac OS, please, help. I'm trying programmatically to change height of window of safari (or other window). I'm was trying used AppleScript and AXUIElementSetAttributeValue of Carbon, but none of these methods can't increase the window bigger than the height of the screen. But, the width changes without any problems. I guess I'd be starting with something like SetWindowPos with SWP_NOSENDCHANGING flag under Win32. Maybe, you can disable this functionality, which monitors the size of the window or completely shutdown the one who is responsible for it? Note that I want to do this programmatically from an external process - I'm not asking how to control just my own app's window size and position. Thanks.

• Problem Writing to Samba Share

  - by Chris

  Hello, I have had a problem writing to a Samba Share I believe you have the answer in this post that you posted in October. Can you tell me how to do this? Thank you very much "On the Samba server, you need to ensure that the nobody user has write permissions to /Windows_Backups/DC. You're forcing everyone to be impersonated by the nobody account, so that account will need file-level permissions on that share directory. Samba will respect local permissions when figuring out who can write where, in this case it is somewhat like Windows."

• CentOS 6 init script doesn't work properly

  - by user711643

  I'm setting up my ruby production server based on CentOS 6. I need a process called god (which is a process monitoring tool) to start at boot. I'm using an init script that I found here. Just as stated in the guide I ran: chkconfig --add god and then chkconfig --level 345 god on After this if I run "service god start|restart" everything works. It loads the available configurations and brings up the related processes (if they are not running). Problem is it doesn't work at boot. If I reboot the system, then I do "ps -aux | grep god". At this point "god" is running but apparently it didn't load the configuration files. If i run again service god restart, it loads everything without problems. What am I doing wrong?

• How to block null/blank user-agents in IIS 7.5

  - by Jeremy

  We are going through a large scale DDOS attack, but it isn't the typical bot-net that our Cisco Guard can handle, it is a BitTorrent attack. This is new to me, so I am unsure how to stop it. Here are the stats IIS is processing between 40 and 100 requests per second from BitTorrent clients. We have about 20% of the User Agents, but the other 75% are blank. We want to block the blank user agents at the server level. What is the best approach?

• What is name server of my domain, pointing to hosted site on Github Pages?

  - by nournia

  I've got one domain name and I want to set it up for my hosted site on Github Pages service. In the documentation this point is mentioned that If you are using a top-level domain like example.com, you must use an A record pointing to 204.232.175.78. But my domain registrar doesn't permit me to add a DNS Record. But only asks me to fill one table like this: Name Server (NS Record) Server Name ......... | Server IP ns53.parsihost.com | 94.232.173.52 ns2.parsihost.com | 206.223.171.254 I asked the registrar about this problem and they said to me "You must put Github's name server in those cells". So, what is the mapping from this table to DNS Records, and what is your advice for filling this kind of table?

• Can I use VT-D with a windows host for a VM?

  - by Journeyman Geek

  I've got a fairly beefy gaming system that I also run occational virtual machines on. It runs windows 8 and the built in hyper V virtual machine software at the moment and has a core i7 3770 (which unlike the unlocked model, should support VT-D), an Asus P8Z77V and a gforce 660 video card(also asus). I figure that if I could use VT-D I could add a cheap dedicated 3d card for a VM, in case I wanted somewhat more than the 'basics'. I know KVM and Xen support this to some level on linux, but can I do so on windows? I'm open to switching VM software if need be.

• Using a Group Managed Service Account (gMSA) for a scheduled task

  - by Trevor Sullivan

  Back in Windows Server 2008 R2, when stand-alone Managed Service Accounts (sMSA) were new, they could not be used to execute scheduled tasks. In Windows Server 2012 however, there is a new type of account called the Group Managed Service Account (gMSA). This type of account is supposedly capable of launching scheduled tasks in the task scheduler on clients & member servers inside of a Windows Server 2012 forest/domain functional level. So far, I have: Established a Windows Server 2012 forest/domain Created a Group Managed Service Account (gMSA) Installed the gMSA on a Windows Server 2012 member server And currently I'm having trouble with: Setting a scheduled task to use the gMSA When I attempt to use a gMSA on a scheduled task, I get the error message that says "The object cannot be found" (paraphrased) message. My question is: How do I configure a Scheduled Task to execute using a Group Managed Service Account (gMSA)?

• Restrict Apache to only allow access using SSL for some directories

  - by DrStalker

  I have an Apache 2.2 server with an SSL certificate hosting several services that should be only access using SSL. ie: https://myserver.com/topsecret/ should be allowed while http://myserver.com/topsecret/ should be either denied or, ideally, redirected to https. http://myserver.com/public should not have this restriction, and should work using either http or https. The decision to allow/deny http is made at the top level directory, and affects all content underneath it. Is there a directive that can be placed in the Apache config to retrict access in this manner?

• How do I know if I need a layer 3 switch?

  - by eekmeter

  We currently have a flat network with a bunch of unmanaged switches. I would like to use VLANs to segregate certain users like guests and I would like to use 802.1x. However, I'm not sure if what I need is a layer 3 or a level 2 switch. From what I understand a layer 3 switch does routing between VLANs. I don't think I need this at the moment but as I said I'm not sure since this is all new to me. What else would a layer 3 switch do for me? Our network is relatively small, less than a 100 users. What exactly does a layer 3 switch do that I can't get with a layer 2 switch? When would I need a layer 3?

• Dell Vostro 3500 battery life remaining missing from Windows 8?

  - by Misha

  On Windows 7 a Vostro 3500 laptop shows the battery life remaining, while on Windows 8 this information appears to be missing. The percentage is still available, but the life remaining is missing. How is battery life remaining calculated and does this require some level of driver support? Is it a standardized interface? Does anybody know which driver is responsible for handling this feature? I want to force the old Windows 7 driver, but I don't know which driver does battery remaining.

• Strange Intermittent Background Sound in Windows 7

  - by NoCarrier

  Ok, this is very strange. Recently, i noticed that every 10-15 seconds, there would be this faint, annoying duh-dum sound coming out of my speakers. (hard to describe. sounds somewhat like the sound windows makes when you unplug a USB device, but not as pronounced and much quieter). I closed every app and ended as many processes as I could, but the sound persists. I look at the volume mixer and sure enough, when the sound occurs, there is a little spike in the level under "System Sounds". I haven't installed any hardware or software in the last several weeks. This started recently - completely out of the blue. Does anyone have any insight?

• Restrict only some plugins to specific sites in Google Chrome

  - by Christian

  I am looking for a way to set up Google Chrome so that it will run a certain plug-in (Java, what else?) only on whitelisted sites, but other plug-ins (like the PDF viewer) everywhere. From playing with the policies available for Chrome, I think there are basically two levels of plug-in management: List of disabled plugins/enabled plugins: Controls whether a plug-in exists for the browser at all This pair of policies applies to plug-ins, but not to sites. Default plug-in settings/Allow plug-ins on sites: Controls on which sites plug-ins can run This set of policies applies to sites, but not to individual plugins, and it cannot override the first pair. There appears to be no way to configure Chrome so that some plug-ins only run on whitelisted sites, but others run everywhere by default. I have also looked at filtering content on the firewall/proxy level, but I'm not convinced it can be done securely there. Filtering by URLs (file names) or content types can be circumvented trivially, and identification by content inspection cannot be safe either.

• Linux QoS (Skype / BitTorent / SIP / HTTP priority)

  - by Andre

  We are configuring a linux box that will act as internet gateway for an office of 30-50 computers. We are using iptables/HTB for traffic shaping. Is there a way to match traffic on L7 level? It's easy to identify traffic by TCP/UDP ports (like SIP and HTTP). But what if we are dealing with Skype & BitTorent? It was surprise for me that there is no powerful and matured sulution for tasks like this. I found only l7-filter (http://l7-filter.clearfoundation.com/) patch for the Linux kernel, but it's no longer supported (it seems to). Moreover it couldn't be compiled with modern Linux kernels. The only option I found was to use a Cisco router. Are there other ways to identify and shape Skype and Bittorent traffic?

• Run 2008 R2 Service under 2000 Domain Account

  - by NoDisassemble

  I'm trying to get a service to run under a domain account. When I try to add the account, I get the error The account name is invalid or does not exist, or the password is invalid for the account name specified I know the account exists and the password is correct. I am also having trouble adding it manually to the "Log on as a service" setting, I get the error An extended error has occured. Failed to save Local Policy Database After a day of research I'm starting to suspect it has to do with it being a 2008 R2 server trying to use a 2000 domain account. I've tried to change the LAN Manager authentication level and the Minimum session security looks okay per my Google digging. I'm not sure what else I can do?

• Smoothwall: How to stop live network traffic displayed in terminal?

  - by Jakobud

  For our network we are working on building a new firewall box and we just installed Smoothwall on it to test it out. When I start up the box, before the login prompt even appears, all of the live IP traffic is appearing in the terminal (source/destination IPs, MACs, Ports, etc). I wait for the boot sequence to finish, but all I see is this IP traffic. The login prompt never comes up. I finally get sick of waiting and press CTRL + C and it says "Entering Run Level 3" and then I get a login prompt finally. Once I login, the IP traffic continues to fly through the terminal even as I'm trying to type commands. How do I turn this stuff off? Is this the default setting for Smoothwall to have all this IP traffic going by on the screen? It essentially renders using the terminal to being useless.

• Missing time zones in OSX and Windows

  - by pellepim

  I am working on a javascript to automatically detect a user's timezone (https://bitbucket.org/pellepim/jstimezonedetect/). But there are two timezones that I have a really hard time to test, since I can not set my system to observe these timezones. The timezones I am talking about are UTC+1245 (Chatham Islands, NZ) and UTC+0845 (Australia/Eucla). As far as I can tell in OSX (Snow Leopard) and in Windows 7 these timezones do not exist as a setting. Granted, very few people live in these areas, and it might just not be worth it. Does anyone know of a way to set these timezones on a system level? In any operating system? If it is not possible in a trivial way, what do people who live in these areas do to get their systems working as they would like?
