  • Accessing CIFS shares from an OS X machine incredibly slow

    - by Aron Rotteveel
    This is a longshot, because this issue seems over-reported and unanswered on the internet (see references below), but it is about time this issue is permanently solved. The facts: Server: Windows Server 2008, acting as a file server Client: OS X Lion 10.7.3. Method of connecting: directly via IP through Finder: smb://192.168.1.100/share The problem: The initial connection attempt takes about a minute. After the connection is made, it takes one more minute to show the directories in Finder. After navigating to any other directory, it takes several seconds/minutes to parse the directory, seemingly based on the size of the contents. Actually, my entire Finder has this problem after connecting. When using Finder to show my desktop, it can literally take up to a minute to load. Obviously, this is not right. I have no clue how to fix this and would appreciate any help I can get. I am unsure about other relevant information I can provide, but if there is any, please let me know so I can update the post. I seem to be not the only one having this problem: Most importantly, an apple.stackexchange.com entry. Unsolved and unanswered. Several users on the Apple support forums. Users on EduGeek.

  • Fixing bent pins on a CPU

    - by Pekka
    While replacing a mainboard in a desktop machine (see related question), I did something stupid. I inserted the CPU into the new mainboard, but didn't check for the right position. When it didn't immediately lock in, I pressed slightly before realizing what was wrong. The result was a number of bent pins. I tried every tutorial that popped up when Googling "CPU bent pins" - using credit cards, sewing needles, and a hunting knife to get the pins back into position - but to no avail: For every pin I get straightened out, two others are bent. I have no problem getting individual pins straightened out, but my many attempts have led to many pins being slightly askew - enough for the CPU not to fit into the socket (An AMD X3 one). Maybe I just lack the motoric finesse. What I would need is some sort of a grid to fix all pins at once. It's a €50 processor so the loss is not catastrophic. But I thought before I go buy a new one, I thought I'd check here whether anybody knows some magic trick, or a cheap generally-available tool to fix this.

  • some HTTPS sites getting blocked on one machine in network

    - by shadowfoxmi
    I have a few computers connected to the internet via a router. I have been having some trouble with this one Windows 7 desktop. I can browse most of the sites without any trouble but some sites where the sign in page switches to a secure connection (https), the page does not load. It's not all of the sites though. I'm able to sign into gmail and a few other services that I know use https . The sites I'm having trouble with; yahoo's sign in page and the one that I have been using to test across different systems, http://iforgot.apple.com (which switchs to https) ;this particular site, i can access from other computers on the network and my phone. I only have windows firewall running and AVG. I even tried to stopping windows firewall but it did not help. Everything was fine last week. All I have installed in the past week is VOIP softwares namely skype, ooVoo and windows live messenger. I'm not sure how to find out what's being blocked and why and how to unblock it? Any suggestions would be greatly appreciated.

    - by InfinityKing
    I recently purchased a new HP Pavilion p6-2265eo. It was then that I realised that it has only one DVI and one HDMI output.. I will connect my TV with the HDMI. so I am letft with only one DVI output. I need to have two monitors. Please help. Should I purchase a new video card and install it? My knowledge is limited. The specifications of my comp says that there is 1 x PCI-E x16, 3 x PCI-E x1. 1) I suppose that the video card already present in my purchase is connected on the PCI-E x16. Am I right? I dont want to open my desktop right now and check it for myself as it can void the warrenty. so I need an experienced person to tell me that. 2) I have an old nvidia geforce 7200 gt. Is it possible for me to connect it to my left over PCI-E x1? I searched for PCI-E x1 on the net and as far as I can understand the slot is too small for my old nvidia geforce 7200 gt graphic card. 3) what are the options? Please help this dummo :) Thankign you in advance,

  • Ubuntu 9.10 won't reboot after replacing a failed drive

    - by user149041
    Hello Serverfault community. I hope someone can shed light on a peculiar problem I am having with an Ubuntu 9.10 server install. I am not a Linux expert but have the responsibility of fixing the box if something goes wrong. DOH! I have Ubuntu 9.10 server installed on on a desktop platform: Compaq Presario SR5027CL. There are two 1TB SATA drives configured in a RAID 1 array; I use the box as an email backup server for a small group of users. Last week one of the drives failed and was replaced with a new drive of the same type. The problem I have been having is getting the box to reboot after a restart or a shutdown halt. The OS and the RAID 1 array are on the same drives that make up the RAID 1 array. The replacement drive (sda) was added to the box and the partitions were created to match the existing good drive (sdb). The array is made up of sda1 and sdb1. I found an interesting point while checking the BIOS settings: there is a "HDD Boot Group Priority" section, and the new drive was selected as the "1. 3rd master"; the server wouldn't boot configured like that, but when I set the old drive to be "1. 4th master", the box will reboot. I'm checking some more things, but I would certainly appreciate any useful information. Thanks in advance.

  • schroot build environment setup how to avoid bind-mount home

    - by minghua
    The recent linux distributions such as Fedora and Ubuntu all use chroot environment to make the build. Because when making the build often it needs to install some special tools, and to install to the existing system. Using chroot avoids making any changes to the host system. To set up such a build environment, the first step is to make a chroot. I'm following the setup guide at https://wiki.debian.org/Schroot [wheezy-test] description=Contains the SPICE program aliases=test type=directory directory=/srv/chroot/test users=jsmith root-groups=root script-config=desktop/config personality=linux preserve-environment=true In the host on my setup the /home is on /dev/mapper. When schroot is entered, the same home is bind-mounted. Is there a way to avoid this? I prefer to use a different /home inside chroot. When changing the type from directory to plain, the binding is not performed. However that also loses /proc, /sys, etc. You'd have to manually bind-mount them. That does not seem to be a good solution. If a simple configuration change is unavailable, any idea where the script is for type=directory? Probably I'll manually modify the script. Thanks in advance for any answers or hints!

  • Create taskbar shortcut to website in Window 7

    - by BJ292
    I'd like to create a shortcut to a website in Windows 7 on the taskbar that is not pinned to the default web browser. Currently if I drag the favicon from the left end of the firefox address bar to the Win 7 taskbar it will pin a shortcut to the firefox browser icon. Similarly if I create a shortcut on the desktop to a website and drag it to the taskbar it will also end up pinned to the firefox icon. The problem with this is to get to that shortcut I have to right click on the firefox icon and then select the pinned shortcut. That is workable for me but I want to do this for a child - so the shortcut needs to be right there on the taskbar as a stand-alone item. There is a workaround that pretty much solves the problem - create a new folder somewhere safe - create the shortcut to the website in the new folder - right click the taskbar and select toolbars - new toolbar - then browse to the folder you created and select it as the new toolbar. The contents of the folder will now appear on the taskbar as shortcuts. You need to drag it from the right hand end of the taskbar into the middle - turn off show titles and show text and make the icon large. I'd call this a 75% solution. Anyone know how to make a web shortcut that looks and operates just like any of the other shortcuts on the taskbar?

  • How to remove all data that a website stores on a PC? [on hold]

    - by s.r.a
    I was a member in a computer forum website (sevenforums.com) for months. Two days ago I created a thread and many members participated in it, some of them asked me some irrelevant questions and I said “this question is irrelevant” and didn’t get them the answer. Thread finished and I could get the answer from another website and posted it to that website to arise members’ knowledge. Yesterday like every day I went to that website and faced a massage which was banning me, and my account was disabled. I shocked and I didn’t have even any option to appeal against that wrong decision. So I had to do something. And I did the following works: 1- I disconnected my Internet connection and cleared all the history data on the browser I use, the Google chrome. 2- I then ran “ccleaner” tool and marked almost all the options and then clicked on “run” button. Then it cleared all the data including the cookies. 3- I connected the machine (desktop) to the Internet and immediately changed my IP address. 4- I created a new Hotmail account and tried to register as a new member to that website (sevenforums.com). 5- I succeeded and my new account was enabled so I start to posting to that website. But unfortunately, after less than 1 minute I faced this message: “You are already banned”! My question is that, how they could know me again? How to create a new account without they know me? Thanks in advance.

  • iphone: Help with AudioToolbox Leak: Stack trace/code included here...

    - by editor guy
    Part of this app is a "Scream" button that plays random screams from cast members of a TV show. I have to bang on the app quite a while to see a memory leak in Instruments, but it's there, occasionally coming up (every 45 seconds to 2 minutes.) The leak is 3.50kb when it occurs.

  • jQuery.closest(); traversing down the DOM not up

  • SQL Server Agent was not running on Server Dynamics CRM 2013

    - by No1_Melman
    I'm trying to install Dynamics CRM 2013 on a server. This server is on a VM. There are several other VMs, an ADDS & DNS, a MSSQL and a WebServer VM. Each server is a Windows Server 2012 R2. The SQL Server is 2012 Enterprise. Each VM is part of the main Domain, set by the ADDS & DNS. NSLookup confirms I can see the computer at the right IP address. Each separate VM has its own static IP, the DNS is set to the ADDS & DNS. I use the domain administrator to log into all the servers, and make the that domain administrator a local administrator. I've set up all the domain users for the CRM and gave them appropriate permissions, I have also added the accounts to the appropriate places, such that the CRM Deployment user is in the SQL security. The SQL Agent is running. SQL server configuration manager has SQL server network configuration TCP/IP enabled to allow remote connections. The SQL server has the domain user as a administrator, which is the same user being used to install the CRM. In the CRM setup i point to the [Servername]\[Instance] and I have also tried just the [Servername]. to make this easier I called the server MSSQL and left the instance name to the default. I even install the MSSQL instance as the domain administrator. CRM can find the ReportServer url. I have enable all the ports required, including: 135, 1433, 1434, 2382, 2383, 4022. 1434 UDP. I feel like I have absolutely done everything, I have google many times and tried all the different methods, and for the life of me I cant seem to get the CRM setup to find the SQL server agent. It passes everything else perfectly fine. I can even ping the MSSQL server. What is the problem, why does the CRM still keep giving the error: SQLSERVERAGENT (SQLSERVERAGENT) service is not running on the server MSSQL On the MSSQL server, the name of the sql server agent service is: SQL Server Agent (MSSQLSERVER)

  • Installing OpenLDAP on Fedora 12: ldap_bind: Invalid credentials (49)

    - by Arcturus
    Hello. I've been trying to set up the OpenLDAP installed by default on Fedora 12, very unsuccessfully. My ultimate goal is to use LDAP authentication for user login and Apache, using the OpenLDAP server running on the same machine. The server is running, but the error I always get when I try to use ldapsearch or ldapadd is: ldap_bind: Invalid credentials (49) I've been following these tutorials, but none of them helped me: http://www.howtoforge.com/openldap_fedora7 http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/ref-guide/s1-ldap-quickstart.html http://www.howtoforge.com/linux_ldap_authentication http://docs.fedoraproject.org/deployment-guide/f12/en-US/html/s1-ldap-pam.html http://www.openldap.org/doc/admin24/quickstart.html First, some components were already installed, and I installed these with yum: yum install openldap-servers openldap-devel Then, I created a basic slapd.conf file in /etc/openldap: database bdb suffix "dc=sniejana-sandbox,dc=com" rootdn "cn=root,dc=sniejana-sandbox,dc=com" rootpw {SSHA}cxdz55ygPu4T3ykg7dgu+L0VRvsFSeom directory /var/lib/ldap/sniejana-sandbox.com I obtained the rootpw with this command: slappasswd -s changeme I also created the /var/lib/ldap/sniejana-sandbox.com directory and made sure the entire contents of /var/lib/ldap were owned by the ldap user. I found two ldap.conf files, one in /etc and one in /etc/openldap. I don't know which is the right one. If I understood correctly, this file is to configure the client. I put this in both: HOST localhost BASE dc=sniejana-sandbox,dc=com I then ran the server with: service slapd start It said OK. Most of the tutorials above say to use the command ldapsearch -D "cn=Manager,dc=my-domain,dc=com" -W to ensure that everything's working. When I execute this command, a password prompt appears, and after entering the password, I get the error. ldapsearch -D "cn=root,dc=sniejana-sandbox,dc=com" -W Enter LDAP password: ldap_bind: Invalid credentials (49) The same thing happens when trying to use ldapadd. I tried with an encrypted and unencrypted password in slapd.conf, it doesn't change anything. Adding a -x for simple authentication doesn't change anything either. netstat -ap confirms the server is listening: tcp 0 0 *:ldap *:* LISTEN 4148/slapd tcp 0 0 *:ldap *:* LISTEN 4148/slapd ps -ef|grep slapd confirms the process is running: ldap 4148 1 0 15:22 ? 00:00:00 /usr/sbin/slapd -h ldap:/// -u ldap Running slaptest procudes config file testing succeeded. I read somewhere that the command ldapsearch -x -b '' -s base '(objectclass=*)' namingContext can confirm the server is running. It appears to work: # extended LDIF # # LDAPv3 # base <> with scope baseObject # filter: (objectclass=*) # requesting: namingContext # # dn: # search result search: 2 result: 0 Success # numResponses: 2 # numEntries: 1 I'm running out of ideas. Am I missing something obvious?

  • What is the difference between Anycast and GeoDNS / GeoIP wrt HA?

    - by Riyad
    Based on the Wikipedia description of Anycast, it includes both the distribution of a domain-name-to-many-IP-mapping across many DNS servers as well as replying to clients with the most geographically close (or fastest) server. In the context of a globally distributed, highly available site like google.com (or any CDN service with many global edge locations) this sounds like the two key features one would need. DNS services like Amazon's Route53, EasyDNS and DNSMadeEasy all advertise themselves as Anycast-enabled networks. Therefore my assumption is that each of these DNS services transparently offer me those two killer features: multi-IP-to-domain mapping AND routing clients to the closest node. However, each of these services seem to separate out these two functionalities, referring to the 2nd one (routing clients to closest node) as "GeoDNS", "GeoIP" or "Global Traffic Director" and charge extra for the service. If a core tenant of an Anycast-capable system is to already do this, why is this functionality being earmarked as this extra feature? What is this "GeoDNS" feature doing that a standard Anycast DNS service won't do (according to the definition of Anycast from Wikipedia -- I understand what is being advertised, just not why it isn't implied already). I get extra-confused when a DNS service like Route53 that doesn't support this nebulous "GeoDNS" feature lists functionality like: Fast – Using a global anycast network of DNS servers around the world, Route 53 is designed to automatically route your users to the optimal location depending on network conditions. As a result, the service offers low query latency for your end users, as well as low update latency for your DNS record management needs. ... which sounds exactly like what GeoDNS is intended to do, but geographically directing clients is something they explicitly don't support it yet. Ultimately I am looking for the two following features from a DNS provider: Map multiple IP addresses to a single domain name (like google.com, amazon.com, etc. does) Utilize a DNS service that will respond to client requests for that domain with the IP address of the nearest server to the requestee. As mentioned, it seems like this is all part of an "Anycast" DNS service (all of which these services are), but the features and marketing I see from them suggest otherwise, making me think I need to learn a bit more about how DNS works before making a deployment choice. Thanks in advance for any clarifications.

  • Sending text messages from Raspberry Pi via email fails

    - by vgm64
    I'm using mailx on my raspberry pi to try to send text messages updates for event monitoring. My phone number: 9876543210 My phone's email-to-text gateway address: [email protected] I can 1) Send emails from my raspberry pi to various email addresses. mail -r [email protected] -s "My Subject" [email protected] < body.txt and off it goes and is successfully delivered. 2) Send emails from various email address (not on RPi) using mailx to the above phone-email address and have them delivered as text messages. However, when sending emails to [email protected] from the Raspberry Pi using mailx the emails seem to spiral into the void and are never heard of again (no errors, no undeliverable messages, nothing). Does anyone know what could be causing this to go awry? Something about the basic deployment of the mail server on the pi? EDIT Based on @kobaltz's suggestion, I used sendmail instead. This led to a hang, then an error that stated that I lacked a fully qualified domain name (FQDN). I then used this website's instructions to add a domain name to the RPi. To paraphrase: I have set the FQDN in /etc/hostname: my-host-name.my-domain.com and /etc/hosts: 127.0.0.1 localhost.localdomain localhost 192.168.0.5 my-host-name.my-domain.com my-host-name Then add to /etc/mail/sendmail.cf: MASQUERADE_AS(`my-domain.com') MASQUERADE_DOMAIN(`my-host-name.my-domain.com') FEATURE(`masquerade_entire_domain') FEATURE(`masquerade_envelope') I put this in /etc/mail/sendmail.cf, BEFORE the MAILER() lines, ran sendmailconfig, answered Yes to the questions about using the existing files, and restarted sendmail. Emails now have the proper domain name. Progress, however, I am now stuck at the following error: 354 Enter mail, end with "." on a line by itself >>> . 050 <[email protected]>...

  • Automatically Applying Security Updates for AWS Elastic Beanstalk

    - by Eric Anderson
    I've been a fan of Heroku since it's earliest days. But I like the fact that AWS Elastic Beanstalk gives you more control over the characteristics of the instances. One thing I love about Heroku is the fact that I can deploy an app and not worry about managing it. I am assuming Heroku is ensuring all OS security updates are timely applied. I just need to make sure my app is secure. My initial research on Beanstalk shows that although it builds and configures the instances for you, after that it moves to a more manual management process. Security updates won't automatically be applied to the instances. It seems there are two areas of concerns: New AMI releases - As new AMI releases hit it seems we would want to run the latest (presumably most secure). But my research seems to indicate you need to manually launch a new setup to see the latest AMI version and then create a new environment to use that new version. Is there a better automated way of rotating your instances into new AMI releases? In between releases there will be security updates released for packages. Seems we want to upgrade those as well. My research seems to indicate people install commands to occasionally run a yum update. But since new instances are created/destroyed based on usage it seems that the new instances would not always have the updates (i.e. the time between the instance creation and the first yum update). So occasionally you will have instances that aren't patched. And you are also going to have instances constantly patching themselves until the new AMI release is applied. My other concern is that perhaps these security updates haven't gone through Amazon's own review (like the AMI releases do) and it might break my app to automatically update them. I know Dreamhost once had a 12 hour outage because they were applying debian updates completely automatically without any review. I want to make sure the same thing doesn't happen to me. So my question is does Amazon provide a way to offer fully managed PaaS like Heroku? Or is AWS Elastic Beanstalk really more of just a install script and after that you are on your own (other than the monitoring and deployment tools they provide)?

  • Flash was "not designed to function across LANs". Any workarounds?

    - by Triynko
    See: http://helpx.adobe.com/flash/kb/problems-using-flash-authoring-across.html Issue When using Adobe Flash across a local area network (LAN) and networked drives/folders, you may experience any of the following problems:" Flash crashes while performing a test movie on FLA files located on a networked drive or folder. FLA files get corrupted when opening from or saving to networked drives or folder. Flash does not reflect changes in custom class after compiling. Flash, Flash Video Encoder, or Adobe Media Encodercrashes or corrupts Flash Video (FLV) files while encoding source located on networked drives or folder. Flash Video Encoder or Adobe Media Encoder crashes or corrupts FLV files where the output folder is a networked drive or folder. Published Flash Player (SWF) files and projectors are unable to load content located on networked drives or folder. More than one instance of a SWF or Projector on client machines cannot play back FLV files located on a networked drive or folder. Reason The Adobe Flash IDE, FLV Encoder, Adobe Media Encoderand Flash Player were not designed to function across LANs. Solution Use of Flash files across local networks is not supported in any context. Published content should access data through a web server. All file sources should be opened and saved on the local system. Using Flash in such a scenario for project collaboration or content deployment is highly discouraged and may corrupt your source files. If you need to work in a collaborative environment or store source files on a server, use the project panel and/or a third-party version control system. SERIOUSLY? I cannot work on files located on a mapped network drive? How did they mess that one up? Does the Flash IDE really open the source file and wipe it clean to do the saving, rather than saving a copy first then replacing it as an atomic file system operation? How hard would it be for them make a dummy temporary file for saving then issue a MOVE command? Any workarounds for this, like something that can make a network drive as stable as a local drive, like some kind of automatic local caching and synching?

  • Assign fixed IP address via DHCP by DNS lookup

    - by Janoszen
    Preface I'm building a virtualization environment with Ubuntu 14.04 and LXC. I don't want to write my own template since the upgrade from 12.04 to 14.04 has shown that backwards compatibility is not guaranteed. Therefore I'm deploying my virtual machines via lxc-create, using the default Ubuntu template. The DNS for the servers is provided by Amazon Route 53, so no local DNS server is needed. I also use Puppet to configure my servers, so I want to keep the manual effort on the deployment minimal. Now, the default Ubuntu template assigns IP addresses via DHCP. Therefore, I need a local DHCP server to assign IP addresses to the nodes, so I can SSH into them and get Puppet running. Since Puppet requires a proper DNS setup, assigning temporary IP addresses is not an option, the client needs to get the right hostname and IP address from the start. Question What DHCP server do I use and how do I get it to assign the IP address based only on the host-name DHCP option by performing a DNS lookup on that very host name? What I've tried I tried to make it work using the ISC DHCP server, however, the manual clearly states: Please be aware that only the dhcp-client-identifier option and the hardware address can be used to match a host declaration, or the host-identifier option parameter for DHCPv6 servers. For example, it is not possible to match a host declaration to a host-name option. This is because the host-name option cannot be guaranteed to be unique for any given client, whereas both the hardware address and dhcp-client-identifier option are at least theoretically guaranteed to be unique to a given client. I also tried to create a class that matches the hostname like this: class "my-client-name" { match if option host-name = "my-client-name"; fixed-address my-client-name.my-domain.com; } Unfortunately the fixed-address option is not allowed in class statements. I can replace it with a 1-size pool, which works as expected: subnet 10.103.0.0 netmask 255.255.0.0 { option routers 10.103.1.1; class "my-client-name" { match if option host-name = "my-client-name"; } pool { allow members of "my-client-name"; range 10.103.1.2 10.103.1.2; } } However, this would require me to administer the IP addresses in two places (Amazon Route53 and the DHCP server), which I would prefer not to do. About security Since this is only used in the bootstrapping phase on an internal network and is then replaced by a static network configuration by Puppet, this shouldn't be an issue from a security standpoint. I am, however, aware that the virtual machine bootstraps with "ubuntu:ubuntu" credentials, which I intend to fix once this is running.

  • How to run Django 1.3/1.4 on uWSGI on nginx on EC2 (Apache2 works)

    - by Tadeck
    I am posting a question on behalf of my administrator. Basically he wants to set up Django app (made on Django 1.3, but will be moving to Django 1.4, so it should not really matter which one of these two will work, I hope) on WSGI on nginx, installed on Amazon EC2. The app runs correctly when Django's development server is used (with ./manage.py runserver 0.0.0.0:8080 for example), also Apache works correctly. The only problem is with nginx and it looks there is something else wrong with nginx / WSGI or Django configuration. His description is as follows: Server has been configured according to many tutorials, but unfortunately Nginx and uWSGI still do not work with application. ProjectName.py: import os, sys, wsgi os.environ.setdefault("DJANGO_SETTINGS_MODULE", "ProjectName.settings") from django.core.wsgi import get_wsgi_application application = get_wsgi_application() I run uWSGI by comand: uwsgi -x /etc/uwsgi/apps-enabled/projectname.xml XML file: <uwsgi> <chdir>/home/projectname</chdir> <pythonpath>/usr/local/lib/python2.7</pythonpath> <socket>127.0.0.1:8001</socket> <daemonize>/var/log/uwsgi/proJectname.log</daemonize> <processes>1</processes> <uid>33</uid> <gid>33</gid> <enable-threads/> <master/> <vacuum/> <harakiri>120</harakiri> <max-requests>5000</max-requests> <vhost/> </uwsgi> In logs from uWSGI: *** no app loaded. going in full dynamic mode *** In logs from Nginx: XXX.com [pid: XXX|app: -1|req: -1/1] XXX.XXX.XXX.XXX () {48 vars in 989 bytes} [Date] GET / => generated 46 bytes in 77 m secs (HTTP/1.1 500) 2 headers in 63 bytes (0 switches on core 0) added /usr/lib/python2.7/ to pythonpath.

  • Lync server 2010 Active Directory Preparation with a Windows Server 2003 DC

    - by juFo
    I'm trying to install Lync server 2010 but i'm stuck for a while now with the "Active Directory Preparation" part of the Lync server 2010 installation. The "Prepare Schema" fails with the following error: "Step 1: Prepare Schema Run once per deployment. Extends the schema for Lync Server. Not Available: Failure occurred while attempting to check the schema state. Please ensure Active Directory is reachable." screenshot: https://skydrive.live.com/#cid=CB15F1A932B364BE&id=CB15F1A932B364BE%211742 The situation: 1 server with Windows Server 2003 (x86), which is the only Domain Controller (DC) 1 server with Windows Server 2008 R2 (x64) where Lync should be installed. First I have found that the DFL/FFL were not correct: On the DC (server2003) I have changed the Domain Functional Level to Windows Server 2003 and also the Forest Functional Level to Windows Server 2003. If I check these settings on the Server2008 with Active Directory Domains and Trusts, I see indeed that the DFL and FFL are being set to Windows Server 2003. (Windows Server 2003 is the minimum required for Lync server 2010) I tried the Lync AD Preparation again but still got the same message: https://skydrive.live.com/#cid=CB15F1A932B364BE&id=CB15F1A932B364BE%211742 I'm logged in on the Server2008 and Server2003 with the domain administrator account. If I check "Active Directory Users and Computers" and go to the directory Users and watch the properties from the Administrator User then it is also a Member of: Domain Admins Domain Users Enterprise Admins Schema Admins Group Policy Creator Owners The firewall on the server2008 is turned off, still nog working So now my question is: what should I do to make the Lync setup (Active Directory Preparation) work? (I would appreciate clear step-by-step suggestions to check.) Thanks in advance. Update 1: Now I've extended AD successfully on the 2003 DC, using this link: http://blogs.pointbridge.com/Blogs/sloan_jason/Pages/Post.aspx?_ID=2 but when I check the Active Directory Preparation again on the Lync install, it still gives me the same error as in the screenshot I've provided. Update 2: I found out that there is a log on "C:\Users\\AppData\Local\Temp\ with this: Get-CSDomainState Get Domain State Error: An error occurred: "Microsoft.Rtc.Management.ADConnect.NoSuitableServerFoundException" "No suitable domain controller was found in domain "OurDomain.LOCAL". Errors:\r\n"OurDCserver.OurDomain.LOCAL5.2 (3790)5.2 (3790) Service Pack1OurDCserver.OurDomain.LOCAL5.2 (3790)5.2 (3790)Service Pack 1"" I thought Lync could be installed with a Windows Server 2003 (according to the documentation on technet) and it doesn't require a SP. :s

  • Installing OpenLDAP on Fedora 12: ldap_bind: Invalid credentials (49)

    - by Alpha Hydrae
    I've been trying to set up the OpenLDAP installed by default on Fedora 12, very unsuccessfully. My ultimate goal is to use LDAP authentication for user login and Apache, using the OpenLDAP server running on the same machine. The server is running, but the error I always get when I try to use ldapsearch or ldapadd is: ldap_bind: Invalid credentials (49) I've been following these tutorials, but none of them helped me: http://www.howtoforge.com/openldap_fedora7 http://www.redhat.com/docs/manuals/linux/RHL-9-Manual/ref-guide/s1-ldap-quickstart.html http://www.howtoforge.com/linux_ldap_authentication http://docs.fedoraproject.org/deployment-guide/f12/en-US/html/s1-ldap-pam.html http://www.openldap.org/doc/admin24/quickstart.html First, some components were already installed, and I installed these with yum: yum install openldap-servers openldap-devel Then, I created a basic slapd.conf file in /etc/openldap: database bdb suffix "dc=sniejana-sandbox,dc=com" rootdn "cn=root,dc=sniejana-sandbox,dc=com" rootpw {SSHA}cxdz55ygPu4T3ykg7dgu+L0VRvsFSeom directory /var/lib/ldap/sniejana-sandbox.com I obtained the rootpw with this command: slappasswd -s changeme I also created the /var/lib/ldap/sniejana-sandbox.com directory and made sure the entire contents of /var/lib/ldap were owned by the ldap user. I found two ldap.conf files, one in /etc and one in /etc/openldap. I don't know which is the right one. If I understood correctly, this file is to configure the client. I put this in both: HOST localhost BASE dc=sniejana-sandbox,dc=com I then ran the server with: service slapd start It said OK. Most of the tutorials above say to use the command ldapsearch -D "cn=Manager,dc=my-domain,dc=com" -W to ensure that everything's working. When I execute this command, a password prompt appears, and after entering the password, I get the error. ldapsearch -D "cn=root,dc=sniejana-sandbox,dc=com" -W Enter LDAP password: ldap_bind: Invalid credentials (49) The same thing happens when trying to use ldapadd. I tried with an encrypted and unencrypted password in slapd.conf, it doesn't change anything. Adding a -x for simple authentication doesn't change anything either. netstat -ap confirms the server is listening: tcp 0 0 *:ldap *:* LISTEN 4148/slapd tcp 0 0 *:ldap *:* LISTEN 4148/slapd ps -ef|grep slapd confirms the process is running: ldap 4148 1 0 15:22 ? 00:00:00 /usr/sbin/slapd -h ldap:/// -u ldap Running slaptest procudes config file testing succeeded.

  • HAProxy causing delay

    - by user1221444
    I am trying to configure HAProxy to do load balancing for a custom webserver I created. Right now I am noticing an increasing delay with HAProxy as the size of the return message increases. For example, I ran four different tests, here are the results: Response 15kb through HAProxy: Avg. response time: .34 secs Transacation rate: 763 trans/sec Throughput: 11.08 MB/sec Response 2kb through HAProxy: Avg. response time: .08 secs Transaction rate: 1171 trans / sec Throughput: 2.51 MB/sec Response 15kb directly to server: Avg. response time: .11 sec Transaction rate: 1046 trans/sec throughput: 15.20 MB/sec Response 2kb directly to server: Avg. Response time: .05 secs Transaction rate: 1158 trans/sec Throughput: 2.48 MB/sec All transactions are HTTP requests. As you can see, there seems to be a much bigger difference between response times for when the response is bigger, than when it is smaller. I understand there will be a slight delay when using HAProxy. Not sure if it matters, but the test itself was run using siege. And during the test there was only one server behind the HAProxy(the same that was used in the direct to server tests). Here is my haproxy.config file: global log 127.0.0.1 local0 log 127.0.0.1 local1 notice maxconn 10000 user haproxy group haproxy daemon #debug defaults log global mode http option httplog option dontlognull retries 3 option redispatch option httpclose maxconn 10000 contimeout 10000 clitimeout 50000 srvtimeout 50000 balance roundrobin stats enable stats uri /stats listen lb1 10.1.10.26:80 maxconn 10000 server app1 10.1.10.200:8080 maxconn 5000 I couldn't find much in terms of options in this file that would help my problem. I have heard suggestions that I may have to adjust a few of my sysctl settings. I could not find a lot of information on this however, most documentation is for Linux 2.4 and 2.6 on the sysctl stuff, I am running 3.2(Ubuntu server 12.04), which seems to auto tuning, so I have no clue what I should or shouldn't be changing. Most settings changes I tried had no effect or a negative effect on performance. Just a notice, this is a very preliminary test, and my hope is that at deployment time, my HAProxy will be able to balance 10k-20k requests/sec to many servers, so if anyone could provide information to help me reach that goal, it would be much appreciated. Thank you very much for any information you can provide. And if you need anymore information from me please let me know, I will get you anything I can.

  • Proper Imaging Procedures to Restore and Deploy Image with Separate System Reserved Partition

    - by alharaka
    UPDATE: As per my experience here, no one responded. If I do not hear back from TechNet forum members about it, I will post a bounty here, if it makes a difference. I have banged my head against a wall for what seems like all week. I am going to explain my simple procedure, and how none of it, absolutely none, seems to work afterword despite few alternatives and everyone on the internet telling assuming this is how to do it. Diskpart Commands to Create FS Structure REM Select the disk targeted for deployment. REM REM NOTE: Usually disk 0, but drive failure can make it external USB REM media. This will erase the drive regardless! select disk 0 REM Remove previous formatting. clean REM Create System Reserved partition bootloader and files. create partition primary size=100 REM Format the volume format fs=ntfs label="System Reserved" quick override noerr REM Assign the System Reserved partition the D: mount for now assign letter=C REM The main system partition, size not specified to occupy whole drive. create partition primary REM Format the volume format fs=ntfs quick override noerr REM Assign the OS partition the D: mount for now assign letter=D REM Make this the active/bootable partition. sel disk 0 sel partition 1 active REM Close out the diskpart session. exit Now, I thought this was madness, but it turns out the System Reserved partition and standard "System Partition" (C:, commonly both the boot and system volumes where you find the Windows directory AND the bootmgr/ntldr hardware files, this is where Windows 7 diverges) as mounted in the Windows PE session where I run these commands do not matter. See reference here. Since this needs to be BitLocker-ready, enter this crappy System Reserved partition that is separate 100MB of awesome that goes before the regular boot volume. I do this, then I proceed to the next step. Deploy System Reserved and Normal System Images REM C is still the "System Reserved Partition", and the image is just like it sounds. imagex /apply G:\images\systemreserved.wim 1 C: REM D is now what will be the C: system partition on reboot, supposedly. imagex /apply G:\images\testimage.wim 1 D: Reboot the system Now, the images I just captured should look good. This is not even sysprepped, but reapplying the same fscking image I prepared on the same reference workstation hours before. Problem is I get 0xc000000e could not detect the accessible boot device \Windows\system32\winload.exe or different kinds of nonsense revolving around being able to find the boot volume with all the right files. I try different variations of things, now none of them work. I tried repairs with bcdboot, with a fresh System Reserved partition or not, bootrec, and maually editing the damn BCD store with bcdedit. I tried finalizing the above process with and without bootsect /nt60 C: /force. I need to wrap up and automate this procedure. What am I doing wrong that does not make the image happy, but really just miserable.
