• Require TLS on RDP for all connections

  - by MarkM

  I have a 2008 DC and a 2008 AD CS server and a Windows 7 client. What I would like is to require the certificate to be used when RDPing to the server. The certificate is valid, and if I connect using the FQDN I am shown that i was authenticated by both the certificate and Kerberos as expected. When I connect with just the hostname I am allowed to connect and am only authenticated by Kerberos, even though I have Require TLS 1.0 set on the server that I am RDPing to. I fully understand that the certificate will not be valid unless the server is accessed by FQDN, what I want to do is disallow connections that do not use the certificate AND Kerberos. I thought that setting Require TLS 1.0 would do it. What am I missing?

• Very slow first handshake Apache

  - by Johan Larsson

  Any one having any ideas where should I start to fix this issue, the first handshake take sometimes up to 20s, but refreshes after that takes only 0.9s. The setup, 100/10 Mbps Windows OS 4GB RAM Intel Core 2 @ 3.0 GHz And 7200 RPM HDD Apache 2.4 No SSL Mod_Security Enabled Mod_Deflate Enabled Mod_Expires Enabled Mod_ReWrite Enabled PHP & MySQL on same machine. I have seen much slower machines preforming better, therefor I think my problem is ony an optimization issue.

• What's the simplest configuration of SVN on a Windows Server to avoid plain text password storage?

  - by detly

  I have an SVN 1.6 server running on a Windows Server 2003 machine, served via CollabNet's svnserve running as a service (using the svn protocol). I would like to avoid storing passwords in plain text on the server. Unfortunately, the default configuration and SASL with DIGEST-MD5 both require plain text password storage. What is the simplest possible way to avoid storing passwords in plain text? My constraints are: Path-based access control to the SVN repository needs to be possible (currently I can use an authz file). As far as I know, this is more-or-less independent of the authentication method. Active directory is available, but it's not just domain-connected windows machines that need to authenticate: workgroup PCs, Linux PCs and software that uses PySVN to perform SVN operations all need to be able to access the repositories. Upgrading the SVN server is feasible, as is installing additional software.

• VPN Connection causes DNS to use wrong DNS server

  - by Bryan

  I have a Windows 7 PC on our company network (which is a member of our Active Directory). Everything works fine until I open a VPN connection to a customer's site. When I do connect, I lose network access to shares on the network, including directories such as 'Application Data' that we have a folder redirection policy for. As you can imagine, this makes working on the PC very difficult, as desktop shortcuts stop working, software stops working properly due to having 'Application Data' pulled from under it. Our network is routed (10.58.5.0/24), with other local subnets existing within the scope of 10.58.0.0/16. The remote network is on 192.168.0.0/24. I've tracked the issue down to being DNS related. As soon as I open the VPN tunnel, all my DNS traffic goes via the remote network, which explains the loss of local resources, but my question is, how can I force local DNS queries to go to our local DNS servers rather than our customers? The output of ipconfig /all when not connected to the VPN is below: Windows IP Configuration Host Name . . . . . . . . . . . . : 7k5xy4j Primary Dns Suffix . . . . . . . : mydomain.local Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : mydomain.local Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : mydomain.local Description . . . . . . . . . . . : Broadcom NetLink (TM) Gigabit Ethernet Physical Address. . . . . . . . . : F0-4D-A2-DB-3B-CA DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::9457:c5e0:6f10:b298%10(Preferred) IPv4 Address. . . . . . . . . . . : 10.58.5.89(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : 31 January 2012 15:55:47 Lease Expires . . . . . . . . . . : 10 February 2012 10:11:30 Default Gateway . . . . . . . . . : 10.58.5.1 DHCP Server . . . . . . . . . . . : 10.58.3.32 DHCPv6 IAID . . . . . . . . . . . : 250629538 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-14-AC-76-2D-F0-4D-A2-DB-3B-CA DNS Servers . . . . . . . . . . . : 10.58.3.32 10.58.3.33 NetBIOS over Tcpip. . . . . . . . : Enabled This is the output of the same command with the VPN tunnel connected: Windows IP Configuration Host Name . . . . . . . . . . . . : 7k5xy4j Primary Dns Suffix . . . . . . . : mydomain.local Node Type . . . . . . . . . . . . : Hybrid IP Routing Enabled. . . . . . . . : No WINS Proxy Enabled. . . . . . . . : No DNS Suffix Search List. . . . . . : mydomain.local PPP adapter Customer Domain: Connection-specific DNS Suffix . : customerdomain.com Description . . . . . . . . . . . : CustomerDomain Physical Address. . . . . . . . . : DHCP Enabled. . . . . . . . . . . : No Autoconfiguration Enabled . . . . : Yes IPv4 Address. . . . . . . . . . . : 192.168.0.85(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : DNS Servers . . . . . . . . . . . : 192.168.0.16 192.168.0.17 Primary WINS Server . . . . . . . : 192.168.0.17 NetBIOS over Tcpip. . . . . . . . : Disabled Ethernet adapter Local Area Connection: Connection-specific DNS Suffix . : mydomain.local Description . . . . . . . . . . . : Broadcom NetLink (TM) Gigabit Ethernet Physical Address. . . . . . . . . : F0-4D-A2-DB-3B-CA DHCP Enabled. . . . . . . . . . . : Yes Autoconfiguration Enabled . . . . : Yes Link-local IPv6 Address . . . . . : fe80::9457:c5e0:6f10:b298%10(Preferred) IPv4 Address. . . . . . . . . . . : 10.58.5.89(Preferred) Subnet Mask . . . . . . . . . . . : 255.255.255.0 Lease Obtained. . . . . . . . . . : 31 January 2012 15:55:47 Lease Expires . . . . . . . . . . : 10 February 2012 10:11:30 Default Gateway . . . . . . . . . : 10.58.5.1 DHCP Server . . . . . . . . . . . : 10.58.3.32 DHCPv6 IAID . . . . . . . . . . . : 250629538 DHCPv6 Client DUID. . . . . . . . : 00-01-00-01-14-AC-76-2D-F0-4D-A2-DB-3B-CA DNS Servers . . . . . . . . . . . : 10.58.3.32 10.58.3.33 NetBIOS over Tcpip. . . . . . . . : Enabled Routing table Network Destination Netmask Gateway Interface Metric 0.0.0.0 0.0.0.0 10.58.5.1 10.58.5.89 20 10.58.5.0 255.255.255.0 On-link 10.58.5.89 276 10.58.5.89 255.255.255.255 On-link 10.58.5.89 276 10.58.5.255 255.255.255.255 On-link 10.58.5.89 276 91.194.153.42 255.255.255.255 10.58.5.1 10.58.5.89 21 127.0.0.0 255.0.0.0 On-link 127.0.0.1 306 127.0.0.1 255.255.255.255 On-link 127.0.0.1 306 127.255.255.255 255.255.255.255 On-link 127.0.0.1 306 192.168.0.0 255.255.255.0 192.168.0.95 192.168.0.85 21 192.168.0.85 255.255.255.255 On-link 192.168.0.85 276 224.0.0.0 240.0.0.0 On-link 127.0.0.1 306 224.0.0.0 240.0.0.0 On-link 10.58.5.89 276 224.0.0.0 240.0.0.0 On-link 192.168.0.85 276 255.255.255.255 255.255.255.255 On-link 127.0.0.1 306 255.255.255.255 255.255.255.255 On-link 10.58.5.89 276 255.255.255.255 255.255.255.255 On-link 192.168.0.85 276 The binding order for the interfaces is as follows: I've not configured the VPN tunnel to use the default gateway at the remote end, and network comms to nodes on both networks are fine. (i.e. I can ping any node on our network or the remote network). I've modified the PPTP connection properties to use the DNS servers 10.58.3.32 followed by 192.168.0.16, yet the query still goes to 192.168.0.16. Edit: The local resources that disappear are hosted on domain DFS roots, which might (or might not) be relevant.

• Windows AD DNS: Event ID 5504

  - by Chris_K

  Two of my AD controllers (both running DNS service) appear to be having a similar issue. Both are throwing lots of events in the DNS events that look like this: Event Type: Information Event Source: DNS Event Category: None Event ID: 5504 Date: 5/24/2010 Time: 11:51:38 AM User: N/A Computer: ALPHA Description: The DNS server encountered an invalid domain name in a packet from 76.74.137.6. The packet will be rejected. The event data contains the DNS packet. That will come with the same event, same time, with a packet from 76.74.137.7 as well. I know this is "Information" not an error, but since it is new and different it bothers me (yes, I fear unexplained change!) Both machines are running Windows 2003 R2 SP2. The DNS servers are not exposed to the internet. Both DNS servers are configured to use OpenDNS for Forwarders. For both servers, this started about a week ago. Any thoughts on: 1) should I be concerned? 2) how can I stop/fix this? To keep it interesting, I have a 3rd AD / DNS box. Same domain, different Active Directory site. Same forwarders, yet doesn't have this issue.

• Changing an MSSQL clustered index field from containing "random" GUIDs to sequential GUIDs - how wil

  - by Eyvind

  We have an MSSQL database in which all the primary keys are GUIDs (uniqueidentifiers). The GUIDs are produced on the client (in C#), and we are considering changing the client to generate sequential (comb) GUIDs instead of just using Guid.NewGuid(), to improve db performance. If we do this, how will this affect installations that already have data with "random" GUIDs as clustered PKs? Can anything be done (short of changing all the PK values) to rebuild the indexes to avoid further fragmentation and bad insert performance? Please give explicit and detailed answers if you can; I am a C# developer at heart and not all too familiar with all the intricacies of SQL Server. Thanks!

• Internet connection sharing: Ubuntu 9.10 Server on Windows 7 and VMWare

  - by avesse

  I'm trying to get Internet Connection Sharing (ICS) working between my Windows 7 RTM host and a Ubuntu 9.10 Server running on VMWare Workstation 6.5, but I have not been able to get it right. Here's what I have done: Configured VMWare to use Host Only networking (I tried NAT as well). Enabled ICS on my host's network connection, allowing VMnet1. After enabling it, Windows informed me that its VMnet1 IP has changed to 192.168.137.1. So in VMWare's Virtual Network Editor I configured VMnet1: Subnet 192.168.137.0 Mask 255.255.255.0 I did the same for DHCP. For NAT i set 192.168.137.1 as Gateway. I cannot ping any sites or get access through apt-get/aptitude install/update, although domains do get resolved to IPs. I have also tried using a static IP in Ubuntu. I don't know if it makes a difference, but my external IP is locked to my host's MAC address.

• Synchronization of volume snapshots when doing whole system backups

  - by intuited

  Is there a way to guarantee consistency across volumes when doing backups from LVM snapshots? Consider this scenario: Some system upgrade is in progress. It will write some files to the /usr volume, and once completed, will record success in the /var volume. As the upgrade is just about complete, I run a backup script that creates snapshots of the /usr and /var volumes, along with the rest of the system's volumes, and proceeds to create backups from those snapshots. Just before the upgrade's last write/flush on the /usr volume completes, the backup script takes its snapshot of /usr. That write completes, and the upgrade operation's success is quickly recorded in the nebulous depths of /var. The backup script takes a snapshot of /var. The backup script creates backups from the snapshots it has, er, snapshotted. So the result of all of this tomfoolery is that the resulting /usr backup contains a file which is missing a few bits, and the /var backup contains metadata indicating that that file is complete and approved for use. Without delving into the details of which operating systems' system upgrade systems would be unfazed by such trifles, is there a way to avoid such problems? At the least this seems like it could cause some application to fail unexpectedly after restoration of such a backup.

• IRC Server For 50 People?

  - by Ferman

  I've seen this question before and I am sure it will be fine but I want assurance before I do it. I am looking at running an IRC server with 128MB of ram and 500GB of BW. The server will usually handle at least 15 people throughout the whole day but there will be times where there can be at least 50 people in it maybe even more. I might also have a few extra channels on there so probably like at least 5 channels and the same people on the one channel will be in the other channels. Also I am trying to decide on the software to use. I am looking at using NGIRCD but I am not sure does anyone else have any recommendations? http://ngircd.barton.de/ I want to say thank you in advanced for anyone that is helping me. :)

• How to setup a simple self-hosted dynamic DNS server

  - by Cerin

  I have a small internal network of physical machines running hypervisors, which in turn run several KVM Ubuntu virtual machines. How would I setup an internal dynamic DNS server so that when I run a script to create a new virtual machine, that VM could automatically register itself in the DNS server? Bind seems to be the standard DNS server for Linux, but it seems designed for a much more "static" DNS model. Dynamically updating this would require a complicated script that would have to SSH into the DNS server, edit configuration files, and then restart the server. This doesn't seem like a very elegant solution. Are there better options? I saw a similar question, although they're asking for a solution for a public setting on Amazon. My servers are entirely private, and I don't want to rely on an external VM host or Dynamic DNS provider.

• My server is slower than the average user's computer, should I still offload Access queries to SQL Server? [closed]

  - by andrewb

  Possible Duplicate: How do you do Load Testing and Capacity Planning for Databases I have a database set up with MS Access 2007 front ends and an SQL Server 2005 back end. At the moment, all the queries are saved in the front end as I've only recently moved to an SQL Server backend. I'm wondering how much of those queries I should save as stored procedures/views on SQL Server. About the system The number of concurrent users is only a handful, though it could be as high as 25 at one time (very unlikely). The average computer has an Intel i3-2120 CPU running at 3.3 GHz, which gets a PassMark score of 3,987, whilst the server has an Intel Xeon E5335 running at 2.0 GHz, which gets a PassMark score of 2,637. Always an awkward situation when an i3 outperforms a Xeon... though the i3 is from Q1 2011 and the Xeon is Q2 2009. There is potential for a server upgrade in the future, though it wouldn't come easy. I'm inclined to move the queries to the back end, as they are beginning to take noticeable time and I figure that is a better way of doing things. I like the idea of throwing everything at the server, then pushing for a server upgrade. It makes more sense in my mind to be upgrading one server rather than 30 PCs. Or am I being overzealous? Why my question isn't a duplicate It seems that my question has been misinterpreted and labelled a duplicate of quite a different question, one about testing and capacity planning. I'll try explain how my question is very different from the linked question. The crux of my question is something like "Even though my server is technically slower, is it better to have it doing more of the queries?" There's two ways that people could have answered this: I agree the server is going to be slower, but the extra benefits of such and such (like the less Access the better) means you should move most to the server anyway. (OR no it doesn't outweigh the benefit, keep them in Access) Actually the server will be faster because of such and such. I'm hoping that people out there could provide some answers like this, and the question in the dupe link doesn't really provide either of these answers. Ok sure, I suppose I could do extensive performance testing to compare Access queries running on a local machine to SQL Server queries running on the server, but that sounds like a very hard task (particularly performance testing of access) compared to someone giving some quick general guidance, and again, my question is looking for a lot more than immediate performance benefit.

• LDAP search filter for Active Directory

  - by Francesco De Vittori

  Hello, I'm trying to look for users inside Active Directory through a LDAP query. Basically I'm searching for the user in this way: Search DN: dc=mydomain, dc=com Filter: (sAMAccountName=USER) where USER is replaced with the provided username. Now if USER is only the username without domain (for ex. "Joe") this works fine. However I receive them in the form (domain\username, for ex. "myDomain\Joe") and obviously the search fails. I see two ways: using a regex inside the Search Filter to discard the domain using a completely different search filter I'm no LDAP expert and I don't even know if it's possible to use regular expressions inside the search filters. Does anyone know if it's possible and how? P.S. I cannot pre-process the username to strip the domain. This cannot be changed, as it's all part of a large system.

• Nginx static files exclude one or some file extensions

  - by Evgeniy

  I'm serving up a static site via nginx. location ~* \.(avi|bin|bmp|dmg|doc|docx|dpkg|exe|flv|gif|htm|html|ico|ics|img|jpeg|jpg|m2a|m2v|mov|mp3|mp4|mpeg|mpg|msi|pdf|pkg|png|ppt|pptx|ps|rar|rss|rtf|swf|tif|tiff|txt|wmv|xhtml|xls|xml|zip)$ { root /var/www/html1; access_log off; expires 1d; } And my goal is to exclude requests like http://connect1.webinar.ru/converter/task/. Full view is like http://mydomain.tld/converter/task/setComplete/fid/34330/fn/7c2cfed32ec2eef6788e728fa46f7a80.ppt.swf. Despite the fact these URLs ends in such a format they are not static, but fake script requests, so I have a problems with them. What is the best way to do this? How can I add an exclusion for this URL or maybe I can to exclude the specific file exptension (.ppt.swf, pptx.swf) from the list of this Nginx location? Thanks.

• Connect two subnets without router

  - by Shcheklein

  I got two Comcast routers with two different subnets on each. Every subnet contains 5 static IPs. Two questions: Are there any problems if both routers and machines from both subnets are connected into one switch? Security issues doesn't matter there. I need to know if there are some performance or other problems. Is it possible to make machines from different subnets to see each other if they all are connected into one switch? Some static routing, add ARP records or somethig else ... I just want to avoid configuring second ethernet adaptors, third router or something. And I need to connect these subnets vai high-speed local network.

• What is the easiest/simplest way to change the HD on a Linux server?

  - by ArmlessJohn

  Hello. I have a machine running Ubuntu Server that has been presenting some HD-related problems. Instead of reinstalling and reconfiguring everything (and to save time) we'd like to copy everything from the current hard drive to a new one and start using it. We only have a single hard drive with a main partition and a swap partition. What tools or methods would you recommend for replacing a hard drive with minimum difficulty and chance of problems? Thank you.

• Apache Proxy Pass and Web Sockets

  - by James

  I'm using Apache with the mod_proxy module to reverse proxy my Node.js application through to port 80, so that we can access it as an internal application. I have a file in sites-enabled which contains this: VirtualHost *:80> DocumentRoot /var/www/internal/ ServerName internal ServerAlias internal <Directory /var/www/internal/public/> Options All AllowOverride All Order allow,deny Allow from all </Directory> ProxyRequests off <Proxy *> Order deny,allow Allow from all </Proxy> ProxyPass / http://localhost:8080/ retry=0 ProxyPassReverse / http://localhost:8080/ ProxyPreserveHost on ProxyTimeout 1200 LogLevel debug AllowEncodedSlashes on </VirtualHost> As I said, our application is written in Node.js and we're using socket.io to make use of web-sockets, as our application also contains realtime elements to it. The problem is, mod_proxy doesn't seem to handle web sockets and we get errors when trying to use them: WebSocket connection to 'ws://bloot/socket.io/1/websocket/nHtTh6ZwQjSXlmI7UMua' failed: Unexpected response code: 502 How can we fix this issue and keep sockets working, as the only way we can get it working currently is to access the site via ip:port which we don't want to do. Also, as a side question, how can I get ErrorDocument to work properly? Our error files are stored in /var/www/internal/public/error/ but they seem to get put through the proxy too?

• Windows file compare (FC) spurious differences

  - by user165568

  I'm getting differences like this: a.txt Betty Davis Cathy Edwards b.txt Betty Davis Cathy Edwards There are only two lines listed in the diff (which doesn't make sense). No CR/LF/Newline funnies. The difference just moves down if I delete lines. Same problem on Win7 and Win2K. The difference seems to go away if I remove all empty lines from the files. The empty lines are correctly terminiated too. Using /C /W (ignore case, ignore whitespace) Has anyone seen this before? What am I doing wrong? How can I fix it? There are real diffs in the file -missing, extra, or re-spelled names- but the files are byte-for-byte identical at the listed diff.

• Ubuntu 14.04 disk utility SMART self-test failed threshold not exceeded

  - by user2323470

  I'm using the "Disks" program in Ubuntu 14.04 (live DVD) to assess the health of a drive I suspect is failing. However, when I first opened the program, it showed that the overall health was OK and all assessments are OK as well. I then tried to run a short self-test, but now the overall assessment shows a red "SELF-TEST FAILED". In the details section it says "Last self-test failed (read)" and "threshold not exceeded". All individual assessments are still OK though!! What I don't understand is, does that mean that the test executed and determined that the drive is a goner, or does it mean that the test didn't actually execute properly?

• Sendmail is refusing connection after configuring SMTP relay

  - by coder

  I'm setting up sendmail on my home computer to use with my webserver. I've set it to use my SMTP server provided by my hosting company. If I use the following command, it works sendmail -Am -t -v and then I enter the to and from emails. But if I try the following, it does not work. sendmail -v [email protected] < test.txt The TO email is the same as in the earlier command, but in this case I haven't specified a FROM e-mail, which I think is the problem. My guess is that it's sending the mail from user@localhost causing the smtp server to reject it. If so, how do I make it send from [email protected]?
