  • Are applications optimized for XenApp?

    - by damitamit
    Our IT dept are about to deploy virtualized apps using Citrix XenApp. One of these apps will be Dynamics AX 4.0 SP2, a ERP client (which I develop on). They have supposedly reached a roadblock because an external 'Dynamics AX Consultant' has told our IT Dept that Dynamics 4 will not work optimally on Citrix and will run very slow because it is not optimized for Citrix. We have it running in a Test environment now and seems ok. They have been told that the only 'solution' is to upgrade to Dynamics AX 2009 where supposedly this problem as been fixed. (not a small task for my team!) When I heard about this, I was quite surprised. From my brief knowledge of Citrix, I thought it would be application independent. How does the citrix app virtualization work, in that a particular app would work better than others on citrix? Would the speed of the virtualized app not just depend on the resources/network connection the citrix server has? FYI, Dynamics AX is a 3-tier client/server system, so the client will be accessing a AOS application server, which then accesses the database. Please enlighten me :)

  • script calling script as other user

    - by viktor tron
    Using CentOs, I want to run a script as user 'training' as a system service. I use daemontools to monitor the process, which needs a launcher script that is run as root: : #!/bin/bash exec >> /var/log/training_service.log 2>&1 setuidgid training training_command This last line is not good enough since for training_command, we need environment for training user to be set. : su - training -c 'training_command' gives 'standard in must be tty' as su making sure tty is present to potentially accept password. I know I could make this disappear by modifying /etc/sudoers a la Bash & 'su' script giving an error "standard in must be a tty" but i am reluctant and unsure of consequences. : runuser - training -c 'training_command' gives runuser: cannot set groups: Connection refused. I found no sense or resolution to this message. I am stuck. Is this something so hard to achieve? I appreciate all insight and guidance to best practice.

  • Re-configure Office 2007 installation unattended: Advertised components --> Local

    - by abstrask
    On our Citrix farm, I just found out that some sub-components are "Installed on 1st Use" (Advertised), which does play well on terminal servers. Not only that, but you also get a rather non-descriptive error message, when a document tried to use a component, which is "Installed on 1st Use" (described on Plan to deploy Office 2010 in a Remote Desktop Services environment): Microsoft Office cannot run this add-in. An error occurred and this feature is no longer functioning correctly. Please contact your system administrator. I have ~50 Citrix servers where I need to change the installation state of all Advertised components to Local, so I created an XML file like this: <?xml version="1.0" encoding="utf-8"?> <Configuration Product="ProPlus"> <Display Level="none" CompletionNotice="no" SuppressModal="yes" AcceptEula="yes" /> <Logging Type="standard" Path="C:\InstallLogs" Template="MS Office 2007 Install on 1st Use(*).log" /> <Option Id="AccessWizards" State="Local" /> <Option Id="DeveloperWizards" State="Local" /> <Setting Id="Reboot" Value="NEVER" /> </Configuration> I run it with a command like this (using the appropriate paths): "[..]\setup.exe" /config ProPlus /config "[..]\Install1stUse-to-Forced.xml" According to the log file, the syntax appears to be accepted and the config file parsed: Parsing command line. Config XML file specified: [..]\Install1stUse-to-Forced.xml Modify requested for product: PROPLUS Parsing config.xml at: [..]\Install1stUse-to-Forced.xml Preferred product specified in config.xml to be: PROPLUS But the "Final Option Tree" still reads: Final Option Tree: AlwaysInstalled:local Gimme_OnDemandData:local ProductFiles:local VSCommonPIAHidden:local dummy_MSCOMCTL_PIA:local dummy_Office_PIA:local ACCESSFiles:local ... AccessWizards:advertised DeveloperWizards:advertised ... And the components remain "Advertised". Just to see if the installation state is overridden in another XML file, I ran: findstr /l /s /i "AccessWizards" *.xml Against both my installation source and "%ProgramFiles%\Common Files\Microsoft Shared\OFFICE12\Office Setup Controller", but just found DefaultState to be "Local". What am I doing wrong? Thanks!

  • Body of email breaks distribution list in exchange?

    - by widgisoft
    Hi, I have a very odd problem that I'm not sure is a programming issue or a server issue :-p. Basically I'm sending an email to an exchange distribution list that includes a PHP stack trace; during certain faults the trace includes really high level information such as the machine's environment variables (during file reads, etc.). I went through a copy of the email line by line until the email sent and it appears the line: [SUDO_COMMAND] => /etc/init.d/httpd restart is the culprit. Adding a string replacement in before the email is sent allows a successful send. What I don't understand is WHY these stream of characters are causing the issue ONLY on the distribution email. If I send the email to myself as well, i.e. "[email protected]; [email protected]", then I get the email fine. Re-ordering the list doesn't make a difference the group never gets the email. Because the individual gets the email and not the group I'm assuming the fault is with exchange and some rogue filtering - I've gone through it with the sysadmins and there's no filtering of any sort on that group... so maybe it's a bug? I can't find anyone else having recorded this specific fault so I figured I'd open it here. For now I'm just not using the distribution list but it'd be nice to eventually find the solution. Many thanks, Chris

  • security update in centos, which way is it?

    - by user119720
    Recently something have been bothered with my mind regarding my linux CentOS box.My client have been asking to set up a CentOS machine in their environment which works as server. One of their requirement is to make sure that the set up is to be as secure as possible. Mostly have been covered except the security update inside CentOS. So my question are as follows: 1.. How to apply the latest security,patches or bug fixes in CentOS? When doing some research, I've been told that we can update the security of CentOS by running yum install yum-security but after install this plug in,seems there is no output for this method.Its like this command is not working anymore. 2.. Can i update the security patches through rpm packages? I couldn't find any site that can download the security patches,enhancement or bug fixes for CentOS.But I know that CentOS have been releasing these update through their CentOS announcement here It just it lack of documentation on how to apply these update into my CentOS installation. For now the only way that I know is to run yum update I am hoping that someone can help me to clarify these matter.Thanks.

  • windows 2003 under Hyper-V - can't send/receive ping

    - by glaucon
    I've installed Windows 2003 x64 R2 SP2 under Hyper-V (the Windows Pro 8 edition). I have a NIC configured but I can't move any traffic on it. In particular I can't send or receive Pings. Scoreboard There is a second VM running Ubuntu under the Windows 8 host which is able to send and receive pings from the host O/S . When I try to ping from Windows 2003 guest to Windows 8 host I get 'Request Timed Out'. When I try to ping from Windows 8 host to Windows 2003 guest I get 'Reply from 192.168.10.107 Destination Host Unreachable'. There's no problem pinging from the Ubuntu guest to the Windows 8 host and no problem pinging from the Windows 8 host to the Unbuntu guest. Environment Integration services are installed on Windows 2003. The windows 2003 needs a static IP address of 192.168.10.15. The Windows 2003 ipconfig output looks like this : While the host o/s ipconfig output looks like this : Event Logs The only things I can see in the event logs which is (a) looks signifcant and (b) is not related to the lack of networking is this : I'm not sure if that's significant or not. Hyper-V and NICs When the Windows 2003 guest was first booted it had no NIC; I subsequently added a 'Legacy Network Connector' which I couldn't get Windows 2003 to recognise; I subsequently removed that and added a 'Standard Network Connector' and at least on the surface this works ... only it doesn't. 'Virtual Network Type' is external. Although I've only mentioned ping there's no other evidence of network activity. 'Allow incoming echo request' is enabled on the Windows 2003 guest. HELP ? What else should I look at or do to resolve this problem ? EDIT 1: I should have said that I turned off the firewall on the W2003 server for a while and retested the pings; same result.

  • Pitfalls to using Gluster as a home/profile directory server?

    - by Bart Silverstrim
    I was asking recently about options for divvying up access to file servers, as we have a NAS solution that gets fairly bogged down when our users (with giant profiles, especially) all log in nearly simultaneously. I ran across Gluster and it looks like it can cluster different physical storage media into a single virtual volume and share it out like a virtual NAS from the client perspective and it support CIFS. My question is whether something like this would be feasible to use for home and profile directories in an active directory environment. I was worried about ACL's, primarily, as I didn't think CIFS was fine-grained enough to support NTFS permissions and it didn't look like Gluster exports those permission levels, just the base permissions for basic file sharing. I got the impression that using Gluster would allow for data to be redundant across multiple servers and would speed up access to the files under heavy load, while allowing us to dynamically boost storage capacity by just adding another server and telling Gluster's master node to add that server. Maybe I'm wrong with my understanding of it though. Anyone else use it or care to share how feasible this is?

  • Server Restart's and Respective Orders

    - by TheD
    EDIT:Not meaning to be disrespectful to any of the answers, but, the main question was whether rebooting a DC at the beginning of a cycle, then all the other servers, or rebooting it at the end once all the others are back online - is there a reason for doing it either way? I'm still not sure based on current responses. This will most likely seem like a fairly, maybe even stupid, question, but it's something I have been wondering about. As part of a regular process for clients servers are restarted remotely after patches and every client tends to have a similar order - but there always seems to be a small debate when it comes down to when do you reboot your DC. For example, 4 servers, 1 DC, 1xExchange, 1xBESX and 1xRandom, lets say it has some CRM software installed, is it best to reboot the DC first, then Exchange, then BESX and so on - or reboot all the servers, then reboot the DC last? - Perhaps it doesn't matter at all and it's just a case of how you have always done it. Would it change in a Hyper-V environment for example, with a physical DC, 1 VHost with all your servers virtualised on that Host? Rebooting the VHost and Virtual Machines first, then the DC at the end, or vice versa? Thanks!

  • SSL in IIS 7 on a subdomain in a web farm

    - by justjoshingyou
    I have been having one of the most frustrating days in my entire IT career. I am trying to install an SSL certificate on a subdomain in a web farm. http://shop.mydomain.com needs to ALWAYS be forced to https://shop.mydomain.com I have a temporary cert issued from verisign on shop.mydomain.com I have installed the cert on the server. The website for shop.mydomain.com is set as a host header in IIS with the DNS entry pointed to the same IP as mydomain.com - which is our load balancer. I actually have 2 load balancers (as needed by our ISP). One redirects all traffic on port 80 out to the different servers on port 80. The other pushes out port 443 to the servers on port 443. shop.mydomain.com is to be the only site protected by SSL at this time. When I add the binding and I navigate to https://shop.mydomain.com it pops up with a warning about the cert being invalid (assumed because this is a test cert), and then it sends the user to http. So, I checked the box "Require SSL and it redirects to http://shop.mydomain.com/default.aspx and displayes an ASP.NET 404 error message. (not the IIS 404 error) I tried removing the binding on the site to port 80 as well with no luck. I am nearly ready to crawl under my desk into the fetal position. How on earth do I make this work? I can't even get it to work on one machine, let alone in the load balanced environment.

  • Deploying workstations - best practices?

    - by V. Romanov
    Hi guys I've been researching on the subject of workstation deployment for a while, and found a ton of info and dozens different methods and tools, but no "best practice" method that doesn't lack at least one feature that i consider required for the solution to be perfect. I'm currently interested in windows workstation deployment, but if the tools can be extended to Linux, then it's an added value. I want the deployment tools I use to be able to do the following: hardware independent - I want my image or installation to have a minimum of hardware and driver dependency, so that i can use a single image/package for all workstations easily updatable - I want to be able to update my image as easily as possible without redeploying/rebuilding/reimaging all configurations PXE bootable deployment - I want the tools to be bootable off the network so that I don't need a boot cd/DOK. scriptable for minimum human input - Ideally, the tool should run automatically after being booted and perform a "default" deployment (including partitioning) unless prompted otherwise. i.e - take a pc, hook it up, power on, PXE boot and forget about it until the OS is deployed. I found no single product or environment that does all this. Closest i came to is the windows deployment services/WIM image format. I also checked out numerous imaging and deployment tools including clonezilla, ghost, g4u, wpkg and others, but most of them lack the hardware Independence and updatability features. We currently have a Symantec Ghost server setup that does imaging over the network, but I'm not satisfied with it as it has all the drawbacks i listed above. Do you have suggestions how to optimize the process of workstation deployment? How do you deploy them in your organization? Thanks! Vadim.

  • cfengine3 file_copy only on source side change

    - by megamic
    I am using the 'digest' copy method for all file copy promises, because of the way we package and deploy software, I cant rely on mtime for the criteria for updating files. For various reasons, I am not employing the client-server approach with a central configuration server: rather we package and deploy our entire configuration module to each server, so from cf-engine's perspective, the source and target are local on the server it is running. The problem I am having with this approach is that the source will always update the target when they differ - which is what I want most of the time, usually because the source has been updated. However, like many other cfengine users, we are running an operational environment, where occasionally emergency fixes have to be applied immediately - meaning we don't have time to rebuild and redeploy a configuration module, and the fix will often be applied by deploying a tarball with specific changes. Of course this is problematic if cf-engine comes along 5 mintues later and reverts the changes. What we would like is to be able to make small, incremental changes to our servers, without them being reverted, until the next deployment cycle at which time the new source files would be copied. We do not consider random file corruption or mistaken changes to involve enough risk to warrant having cfengine constantly revert deployments to their source copy - the ability to deploy emergency fixes and have them stay that way until the next deployment would be of much greater value and utility. So, after all that, my question is this: is cf-engine capable of detecting whether it was the source or target that changed when the files differ, and if so, is their a way to use the 'digest' copy method but only if the source side changed? I am very open to other ideas and approaches as-well, as I am still quite new to this whole configuration management thing.

  • Windows clients unable to access Samba share on AD joined Linux box every 7 days

    - by Hassle2
    The problem: Every 7 days, 2 Windows Servers are unable to access a SMB/CIFS share. It will start working after a handful of hours. The environment: OpenFiler Linux box joined to 2003 AD Domain Foreground app on Win2003 server access the SMB/CIFS share with windows credentials Another process on Win2008 access the share via SQL Server with windows credentials The Samba version on the Linux box is 3.4.5. Security is set to ADS wbinfo and getent return back expected users and groups Does not look to be a double hop issue as it's always the 2 accounts, regardless of the calling user. There is a DNS entry in both forward and reverse lookup zone for the linux box The linux box's computer object in active directory shows that it was modified around/at the same time that the two clients started failing to access the share Trying to access the share via IP works when by name does not Rebooting the Windows server takes care of it (it's production and only restarted it once) Restarting smbd, winbind, nmbd had no effect Error in samba log for the client in question: smbd/sesssetup.c:342(reply_spnego_kerberos) Failed to verify incoming ticket with error NT_STATUS_LOGON_FAILURE! The Question: Does this look like the machine account password is changing (hence the AD object showing the updated modified date) or are the two windows clients unable to request a new ticket that works against this linux box?

  • Can't get simple Apache VHost up and running

    - by TK Kocheran
    Unfortunately, I can't seem to get a simple Apache VHost online. I used to simply have one VHost which bound to all: <VirtualHost *:80>, but this isn't appropriate for security anymore. I need to have one VHost for localhost requests (ie my dev server) and one for incoming requests via my domain name. Here's my new VHost: NameVirtualHost domain1.com <VirtualHost domain1.com:80> DocumentRoot /var/www ServerName domain1.com </VirtualHost> <VirtualHost domain2.com:80> DocumentRoot /var/www ServerName domain2.com </VirtualHost> After I restart my server, I see the following errors in my log: [Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs [Wed Feb 16 11:26:36 2011] [error] [client ####.###.###.###] File does not exist: /htdocs What am I doing wrong?

  • SharePoint Search: processing filenames containing underscores

    - by Todd Owen
    We use SharePoint Server 2007 to allow employees to search network file shares, but it seems that underscores in filenames are not treated as word separators when indexing the files. As a result, a search for chocolate will: match "chocolate milkshake.doc" but not match "chocolate_cake.doc" (Of course, this is a simplified example; in practice the content of the second file might include the word "chocolate" and match on that instead of the filename. But the problem itself is real enough, because a common scenario in a corporate environment is that a user knows the the partial name of the file they are looking for and expects to see matching filenames at the top of the search results. And using underscores in filenames is a widely used convention within our company). Underscores are not treated as word separators in the file content either, although this is less of a concern for us. The root cause of this problem is possibly related to the behaviour of the word breakers that SharePoint uses (i.e. the language-specific DLLs that implement the IWorkBreaker interface), although I haven't confirmed this yet. Does anyone know of a workaround for this issue? I have tested with Search Server 2008 Express too (which is based on the same technology), and it is also affected. I do not know whether the problem is fixed in SharePoint 2010 or not.

  • fedora apache/nginx pylons

    - by microchasm
    I'm trying to wrap my head around Pylons and how it works. So far... it's been confusing... I'm using EC2 with Fedora8. Everything is working so far (i.e. I have Pylons/python et al installed and after creating a test app and running paster serve I can access the default page via my domain name). As the Pylons docs explain and as I understand, the built in paster serve server is not suited for a production environment. What I am not clear on, then, is what to do next... It seems like nginx is a good option, but I am more familiar with Apache (like .0002%). I plan on having virtualhosts (which nginx says can accomodate). However, I am totally unclear on how the big picture is supposed to work. In order to serve an app, does paster serve need to be running? Does then nginx/apache basically just act as a proxy to shuttle connections to the paster server? How do I start it so it doesn't terminate after closing the ssh connection? If running multiple apps, what do I set as the host/port in development.ini to differentiate the apps? Or if this is not the right way, how do I differentiate beween apps? I am more familiar with MySQL, but willing to negotiate PostgreSQL if it's a better fit. Is it? Is virtualenv a prerequisite to running multiple apps on the same machine? Thanks in advance for any tips.

  • Missing Data on VMWare Virtual Disk

    - by Lachlan McDonald
    Evening all, I've got a considerable problem I'm hoping to get some resolution on. I had two VMWare 6.5 virtual machines, one running Ubuntu 9.10 and the other Ubuntu 10.04. I used 9.10 as a testing server, so I could install a LAMP environment to prepare some code. Over the months I took a number of snapshots of this VM just in case something went wrong, and did a full copy of the entire VM a month ago. I created the 10.04 VM when Lucid Lynx launched so I could continue development on a fresh install. To get the files over, I simply added the 9.10 virtual disk into the 10.04 VM, grabbed some of the files I needed, and dismounted it. Unknown to me at the time, the changes to the 9.04 virtual disk meant that I could no longer boot it with the 9.10 VM. I'd always get the "The parent virtual disk has been modified since the child was created." error. I decided this was a good time to backup all the critical files, but now whenever I open the 9.04 disk to get the data it isn't in the same state as it was earlier. My question is; is it possible when I'm mounting the virtual disk that I'm not seeing the most recent snapshot, or in my blundering, have I lost the virtual disk. Cheers

  • Backup strategy for developer-focused Apple environments?

    - by ewwhite
    It's interesting to see the technological split between structured corporate environments and more developer-driven/startup environments. Some of the Microsoft technologies I take for granted (VSS, Folder Redirection, etc.) simply are not available when managing the increasing number of Apple laptops I see in DevOps shops. I'm interested in centralized and automated backup strategies for a group of 30-40 Apple laptops... How is this typically done safely and securely, assuming these are company-owned machines (versus BYOD)? While Apple has Time Machine, it's geared toward individual computer backups and doesn't seem to work reliably in a group setting. Another issue with these workstations is the presence of Vagrant/Virtual Box VMs on the developers' systems. Time Machine and virtual machines typically don't work well unless the VMs are excluded from the backup set. I'd like a push-based backup process with some flexible scheduling options. I know how to handle the backend storage, but I'm not sure on what needs to be presented to the client systems. Due to the nature of the data here, cloud-based backup may not be a viable option. Any suggestions about how you handle this in your environment would be appreciated. Edit: The virtual machine backups are no longer important. They can be excluded from the process and planning.

  • Windows 2008 R2 AWS CloudFormation Elastic beanstalk configuration

    - by Webmonger
    I'm looking for some configuration advice. I have a need for a load balanced windows environment with shared media across all instances that are hosting the app. The best explanation i can give is that there will be multiple Windows 2008 server with IIS hosting the app going through an ELB to load balance. Users must be able to upload content (images, video etc...) to the site that will be hosted. When a user uploads media it needs to be kept on a shared location so all windows IIS instances can access the files, I can't host the files on S3 because of the app architecture so they need to be in a place where all IIS server will have access. In addition I need to run an update each IIS server instance that updates a local memory cache when SQL data is updated. I was thinking of a configuration like this: [ELB] - [Win 2008 IIS (multiple servers)] - [Win 2008 File & SQL Server(possibly RDS?)] Does this configuration make sense? If not could you provide an idea of how I should configure it. Thanks in advance

  • SSL setup: UCC or wildcard certificates?

    - by quanza
    I've scoured the web for a clear and concise answer to my SSL question, but to no avail. So here goes: I have a web-service requiring SSL support for authentication pages. The root-level domain does not have the "www" - i.e., secure://domain.com - but localized pages use "language-code.domain.com", i.e. secure://ja.domain.com So I need at least a wildcard SSL certificate that supports secure://*.domain.com However, we also have a public sandbox environment at sandbox.domain.com, which we also need to support under localized domains - so secure://ja.sandbox.domain.com needs to also work. The previous admin managed to purchase a wildcard SSL certificate for .domain.com, but with a Subject Alternative Name for "domain.com". So, I'm thinking of trying to get a wildcard certificate with SANs defined as "domain.com" and ".*.domain.com". But now I'm getting confused because there seem to be separate SAN certificates, also called UCC certificates. Can someone clarify whether it's possible to get a wildcard certificate with additional SAN fields, and ultimately what the best way is to support: secure://domain.com secure://.domain.com secure://.*.domain.com with the fewest (and cheapest!) number of SSL certificates? Thanks!

  • Problems with X11GraphicsDevice on Suse 11

    - by Daniel
    Hi, On servers running Suse 11 I'm experiencing hangups in sun.awt.X11GraphicsDevice.getDoubleBufferVisuals(Native Method) when connecting via Citrix (and setting DISPLAY to localhost:11.0). Running exactly the same code in exactly the same environment, excepth through Exceed (with DISPLAY set to my workstation's IP) it runs like clockwork. The error is not intermittent, it happens every time Reinstalling the OS does not help Can not reproduce it on Suse 10 This is what the main thread stack looks like: [junit] "main" prio=10 tid=0x0000000040112000 nid=0x6acc runnable [0x00002b9f909ae000] [junit] java.lang.Thread.State: RUNNABLE [junit] at sun.awt.X11GraphicsDevice.getDoubleBufferVisuals(Native Method) [junit] at sun.awt.X11GraphicsDevice.makeDefaultConfiguration(X11GraphicsDevice.java:208) [junit] at sun.awt.X11GraphicsDevice.getDefaultConfiguration(X11GraphicsDevice.java:182) [junit] - locked <0x00002b9fed6b8e70 (a java.lang.Object) [junit] at sun.awt.X11.XToolkit.(XToolkit.java:92) [junit] at java.lang.Class.forName0(Native Method) [junit] at java.lang.Class.forName(Class.java:169) [junit] at java.awt.Toolkit$2.run(Toolkit.java:834) [junit] at java.security.AccessController.doPrivileged(Native Method) [junit] at java.awt.Toolkit.getDefaultToolkit(Toolkit.java:826) [junit] - locked <0x00002b9f94b8ada0 (a java.lang.Class for java.awt.Toolkit) [junit] at java.awt.Toolkit.getEventQueue(Toolkit.java:1676) [junit] at java.awt.EventQueue.invokeLater(EventQueue.java:954) [junit] at javax.swing.SwingUtilities.invokeLater(SwingUtilities.java:1264) ... Has anyone experienced something similar? Could this be a problem in Suse 11's display handling? I'm thankful for any input at this point - I'm fresh out of ideas :)

  • Current wisdom on SQL Server and Hyperthreading?

    - by BradC
    Lots of articles out there (see Slava Oks's original SQL 2000 article and Kevin Kline's SQL 2005 update) recommend disabling hyperthreading on SQL servers, or at least testing your specific workload before enabling it on your servers. This issue is gradually becoming less relevant as true multi-core processors replace hyperthreaded ones, but what's the current wisdom on this issue? Does this advice change any with SQL 2005 64-bit, or SQL 2008, or Windows Server 2008? Ideally, this should be tested in advance in a staging environment, but what about for servers that have already made it into production with HT enabled? How can I tell if performance issues we're experiencing might be related to HT? Is there some specific combination of perfmon counters that might point me in that direction, as opposed to all the other things I normally pursue when working on improving SQL performance? Edit: This is especially attractive because of the potential for an across the board improvement for some of my high-cpu servers, but the client is going to want to see something concrete that helps me identify which servers really could benefit from disabling hyperthreading. Of course, conventional performance troubleshooting is ongoing, but sometimes any little bit helps.

  • Default Gateway solution on NAT'd network (best options)

    - by kwiksand
    I've recently changed a network from a bunch of machines exposed to the net on a network to a more security conscious Firewall-fronted network with a DMZ for public services. Everything's mostly working perfectly now, but I've got the old problem of NAT Loopback where a machine within the LAN wants to access a public service via the public/external IP. I've solved this problem previously in a small/SOHO environment simply using NAT loopback features of the router in use or a simple iptables rule to do the same, but I want to make sure I make the most resilient choice with the least concern. It seems I can: Use iptables as I've said to DNAT and MASQUERADE the change source/destination so the connection works correctly i.e iptables -A PREROUTING -t nat -d ip.of.eth0.here -p tcp --dport 8080 -j DNAT --to 192.168.0.201:8080 iptables -t nat -A POSTROUTING -s 192.168.0.0/24 -p tcp --dport 8080 -d 192.168.0.201 -j MASQUERADE Use split DNS, with internal mappings for public IP's Potentially do some route nastyness by setting the Default Gateway to use a different externally exposed IP to then come back in the public route (messy) Someone mentioned putting the Default Gateway within the DMZ as well (on serverfault), but I can't find the post again. I'm sure this is a common issue for many with NAT'd networks, but I've not really seen the perfect solve all when it comes to fixing this problem. What is your opinion?

  • Windows 7 network performance tuning for LAN

    - by Hubert Kario
    I want to tune Windows 7 TCP stack for speed in a LAN environment. Bit of background info: I've got a Citrix XenServer set up with Windows 2008R2, Windows 7 and Debian Lenny with Citrix kernel, Windows machines have Tools installed the iperf server process is running on different host, also Debian Lenny. The servers are otherwise idle, tests were repeated few times to confirm results. While testing with iperf 2008R2 can achieve around 600-700Mbps with no tuning what so ever but I can't find any guide or set of parameters that will make Windows 7 achieve anything over 150Mbps with no change in TCP window size using -w parameter to iperf. I tried using netsh autotuining to disabled, experimental, normal and highlyrestricted - no change. Changing congestionprovider doesn't do anything, just as rss and chimney. Setting all the available settings to same values as on Windows 2008R2 host doesn't help. To summarize: Windows 2008R2 default settings: 600-700Mbps Debian, default settings: 600Mbps Windows 7 default settings: 120Mbps Windows 7 default, iperf -w 65536: 400-500Mbps While the missing 400Mbps in performance I blame on crappy Realtek NIC in the XenServer host (I can do ~980Mbps from my laptop to the iperf server) it doesn't explain why Windows 7 can't achieve good performance without manually tuning window size at the application level. So, how to tune Windows 7?

  • How to enable error log in lighttpd properly?

    - by Tomaszs
    I have a Centos 5 system with Lighttpd and fastcgi enabled. It does log access but does not log errors. I have Internal Server Error 500 and no info in log and when I try to open not -existing file also - no info in error log. How to enable it properly? Below is list of modules that I've enabled: server.modules = ( "mod_rewrite", "mod_redirect", "mod_alias", # "mod_access", # "mod_cml", # "mod_trigger_b4_dl", # "mod_auth", "mod_status", "mod_setenv", "mod_fastcgi", # "mod_webdav", # "mod_proxy_core", # "mod_proxy_backend_fastcgi", # "mod_proxy_backend_scgi", # "mod_proxy_backend_ajp13", # "mod_simple_vhost", # "mod_evhost", # "mod_userdir", # "mod_cgi", # "mod_compress", # "mod_ssi", # "mod_usertrack", # "mod_expire", # "mod_secdownload", # "mod_rrdtool", "mod_accesslog" ) Here are setting of debugging: ## enable debugging #debug.log-request-header = "enable" #debug.log-response-header = "enable" #debug.log-request-handling = "enable" debug.log-file-not-found = "enable" #debug.log-condition-handling = "enable" Setting of path to error and access log: ## where to send error-messages to server.errorlog = "/home/lxadmin/httpd/lighttpd/error.log" #### accesslog module accesslog.filename = "/home/lxadmin/httpd/lighttpd/ligh.log" Settings of fastcgi: fastcgi.debug = 1 fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 12, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "2", "PHP_FCGI_MAX_REQUESTS" => "500" ) ))) And in included config file I have: server.errorlog = "/home/httpd/mywebsite.com/stats/mywebsite.com-error_log" What comes to log files: /home/httpd/mywebsite.com/stats/ -rw-r--r-- 1 apache apache 5173239 May 16 11:34 mywebsite.com-custom_log -rwxrwxrwx 1 root root 0 Mar 27 2009 mywebsite.com-error_log /home/lxadmin/httpd/lighttpd/ -rwxrwxrwx 1 apache apache 2184 Apr 22 22:59 error.log -rwxrwxrwx 1 apache apache 6088621 May 16 11:26 ligh.log I gave error logs chmod 777 for a try to check if it's the issue, but apparently it's not. So my question is: what to do to have error log enabled?

  • High latency issue for web service call from amazon aws ec2 to local server

    - by SibzTer
    We have a legacy web application that is running in our data center on premises located in Houston. We have a developed a new .net 4 based web application in order to provide new features to customers. The new web application is hosted in amazon aws ec2 environment (N. Virginia region us-east-1b zone). In order to get seamlessly integrate with the legacy application the new web application makes web service calls to retrieve data. We are seeing an unusually high latency time in the order of 5+ seconds for these web service calls. The exact same web service call returns in less than a second on our local PCs (which makes sense given physical proximity to the actual server). The weird part is that we have developers in California who also have the same milliseconds response time. We are testing the web service response using third party tools such as SoapUI, Google Chrome extensions such as Advanced REST Client, Postman REST Client, etc. As if this wasnt weird enough, we have noticed the same low latency from certain other ec2 instances while testing which are in the same region and availability zone as well. If we experienced the high latency consistently from all the ec2 instances I could understand. But there is something else going on. Comparing the various stats and results between the low latency and high latency ec2 servers do not show any significant differences: ping (constant 40ms), tracert, winmtr, etc. We have instances that are in the VPC as well. So I tried both the public and private IP address of the web service host server and that didnt make a difference either for the above results. We need to resolve this latency issue as this is causing the resulting web pages to load very slowly (almost 15+ seconds which is simply unacceptable). The ec2 instances have Windows Server Datacenter 64 bit. Let me know if there is any other infor I can provide to help diagnose this.
