• Intermittent unavailability of an instance in a failover cluster while a standby node is offline in

  - by Emil Fridriksson

  Hi everyone. I've got a small failover cluster that I run for the websites my company has. During a RAM upgrade of the standby server, our websites started to show errors about not being able to access the database server. I verified that the instance was indeed up and the server accessable via remote desktop. I also tried a SQL connection to it and it worked, but that might have been after it became available again. This happened on and off until we were able to roll back the hardware changes that were in progress on the standby server and we were able to bring it back up. There was nothing of interest in the SQL Server log, but there is a continous log for the whole duration of the problem, so there was no restart of the SQL Server service. The event viewer is of more interest, since it shows events relating to the heartbeat network card, but I don't know how that would affect the availability of the server, since the standby node is offline. I'd appreciate any help you can provide, it's not very redundant if the setup depends on the standby server being up. :) Here are the event logs from the time of the problem, I include all of them since I can't seem to see what could possibly be the cause of the problem. Event log: http://hlekkir.com:800/htmltable.htm

• How to connect to local instance of SQL Server 2008 Express

  - by Billy Logan

  I just installed SQL Server 2008 Express on my windows 7 machine. I previously had 2005 on here and used it just fine with the old SQL Server Management Studio Express. I was able to connect with no problems to my PC-NAME\SQLEXPRESS instance. I uninstalled 2005 and SQL Server Management Studio Express. I then installed SQL Server 2008 Express on my machine and elected to have it install SQL Server Management Studio. Now, when I try to connect to PC-NAME\SQLEXPRESS (with Windows Authentication, like I always did), I get the following message: Cannot connect to PC-NAME\SQLEXPRESS. A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: SQL Network Interfaces, error: 26 - Error Locating Server/Instance Specified) (Microsoft SQL Server, Error: -1) For help, click: http://go.microsoft.com/fwlink?ProdName=Microsoft+SQL+Server&EvtSrc=MSSQLServer&EvtID=-1&LinkId=20476 When I went to the help link it mentions, the help page suggests the following: * Make sure that the SQL Server Browser service is started on the server. * Use the SQL Server Surface Area Configuration tool to enable SQL Server to accept remote connections. For more information about the SQL Server Surface Area Configuration Tool, see Surface Area Configuration for Services and Connections. I did try starting the SQL Server Browser, but don't see that the Surface Area Configuration is installed with this express version. I had seen another user with an almost exact same issue that was missing the database engine on install. If that were the case how could i test for that and where would i go to download that install. Thanks in advance, Billy

• When importing an Access table into Excel, a look-up column is showing all values as numbers

  - by user3651997

  I have a basic Access to Excel question that has me frustrated. I have two Access 2010 data tables. One is a list of managers. The primary key is a manager ID (which is an autonumber because managers can have the same name), and each row also has manager name, manager email, etc. The second data table is a list of departments. The primary key for each row is a unique department code, and the foreign key is a manager ID (autonumber). I used the Look-up Wizard to create this connection. However, Access does not show the manager ID in the foreign key location. It shows Manager Name like I requested when I used the Look-up Wizard. Now I am trying to import the second table (departments) into Excel 2010. I clicked import from Access, chose the Department table, and everything popped into Excel. BUT, the Manager Name column is showing Manager ID instead. So I have a list of numbers instead of names. How can I make Excel show what I see in Access? Thanks!

• Workstations cannot see new MS Server 2008 domain, but can access DHCP.

  - by Radix

  The XP Pro workstations do not see the new replacement domain upon boot; they only see their cached entry for the old (server 2003) domain controller. The old_server is not connected to the network. I have DHCP working with the same scope as the old_server. In my "before-asking" search for a solution I came across the following two articles, and I recall doing things as suggested by the articles. http://www.windowsreference.com/windows-server-2008/how-to-setup-dhcp-server-in-windows-server-2008-step-by-step-guide/ http://www.windowsreference.com/windows-server-2008/step-by-step-guide-for-windows-server-2008-domain-controller-and-dns-server-setup/ The only possible issue is: I was under the impression that the domain netbios needed to match the DC's netbios. The DC netbios is city01 while the domain's FQDN is city.domain.org (I think this is mistaken and should have been just domain.org) But, the second link led me to a post which I believe answers my question. I did as they instructed by opening Local Area Connection Properties, then selecting TCP/IPv4 and setting the sole preferred DNS server to the local hosts static IP (10.10.1.1). Search for "Your problems should clear up" for the post I'm referencing: http://forums.techarena.in/active-directory/1032797.htm Have I misunderstood their instructions? I am hoping to reach the point where I can define users and user groups. Also, does TechNet have a single theoretical overview document I could read. I really don't like treating comps as magic. I will be watching this closely and will quickly answer any questions. If I've left anything out it is because I did not know it was needed. PS: I am loath to ask obviously basic questions, but I am tired and wish to fix this before tomorrow. Also, this is my first server installation, thank you for your help.

• apache2: ssl_error_rx_record_too_long when visiting port 80? help!

  - by John

  Hi, I have an Ubuntu 10 x64 server edition machine. I got a second IP and configured /etc/network/interfaces like so (actual IPs and gateways removed): [code] auto lo iface lo inet loopback iface eth0 inet dhcp auto eth0 auto eth0:0 iface eth0 inet static address [ my first IP ] netmask 255.255.255.0 gateway [ my first gateway ] iface eth0:0 inet static address [ my second IP ] netmask 255.255.255.0 gateway [ my second gateway ] [/code] /etc/apache2/ports.conf: [code] Listen 80 NameVirtualHost [ my first IP ]:80 NameVirtualHost [ my second IP ]:80 # If you add NameVirtualHost *:443 here, you will also have to change # the VirtualHost statement in /etc/apache2/sites-available/default-ssl # to # Server Name Indication for SSL named virtual hosts is currently not # supported by MSIE on Windows XP. Listen 443 NameVirtualHost [ my first IP - some site is running SSL successfully using it ]:443 Listen 443 [/code] /etc/apache2/sites-enabled/mysite.conf: [code] ServerName mysite.com Include /var/www/mysite.com/djangoproject/apache/django.conf [/conf] [/code] Then when visiting http[mysite].com:80 or http[mysite].com (:// removed because serverfault doesn't allow me to post hyperlinks), I get: [code] An error occurred during a connection to [mysite].com. SSL received a record that exceeded the maximum permissible length. (Error code: ssl_error_rx_record_too_long) [/code] My guess is that the configuration file is not being picked up, and apache is therefore looking for the default-ssl file, which is not in conf-enabled. If I were to configure that file properly, it seems I would successfully connect to whatever default directory is specified in the default-ssl file. But I want to connect to my website. Any ideas? Thanks in advance!

• Linux machine can't find its tape drive

  - by Kyle Hodgson

  I have an older HP NetServer LPr with what is apparently a Symbios SCSI card connecting to a Quantum SuperLoader 3 that is DLT based. From time to time, we seem to lose the connection to the autoloader. It's usually due to flaky power, but not totally sure why; sometimes when this happens the Autoloader's LED's are orange and it needs to be power cycled. The annoying workaround currently is to reboot the machine. As it is our production VPN and DNS server in addition to being our backup server, this is less than optimal. In Debian (Sarge) is there not some command one can type to get the card to notice that it has the autoloader connected again? dcr1:/proc# grep -i symbios /proc/pci SCSI storage controller: LSI Logic / Symbios Logic 53c895 (rev 1). dcr1:/proc# uname -a Linux dcr1 2.4.27-3-686 #1 Tue Dec 5 21:03:54 UTC 2006 i686 GNU/Linux dcr1:/proc# mt status mt: /dev/tape: No such device dcr1:/proc# ls -l /dev/tape lrwxrwxrwx 1 root root 8 2007-02-07 16:01 /dev/tape -> /dev/st0 dcr1:/proc# That mt status command will show the actual st0 status when things are working correctly. The No such device message is usually the second clue that we need to reboot - the first clue is usually that the backups didn't run.

• Route forwarded traffic through eth0 but local traffic through tun0

  - by Ross Patterson

  I have a Ubuntu 12.04/Zentyal 2.3 server configured with WAN NATed on eth0, local interfaces eth1 and wlan0 bridged on br1 on which DHCP runs, and an OpenVPN connection on tun0. I only need the VPN for some things running on the gateway itself and I need to make sure that everything running on the gateway goes through the VPNs tun0. root:~# route Kernel IP routing table Destination Gateway Genmask Flags Metric Ref Use Iface default gw... 0.0.0.0 UG 100 0 0 eth0 link-local * 255.255.0.0 U 1000 0 0 br1 192.168.1.0 * 255.255.255.0 U 0 0 0 br1 A.B.C.0 * 255.255.255.0 U 0 0 0 eth0 root:~# ip route 169.254.0.0/16 dev br1 scope link metric 1000 192.168.1.0/24 dev br1 proto kernel scope link src 192.168.1.1 A.B.C.0/24 dev eth0 proto kernel scope link src A.B.C.186 root:~# ip route show table main 169.254.0.0/16 dev br1 scope link metric 1000 192.168.1.0/24 dev br1 proto kernel scope link src 192.168.1.1 A.B.C.0/24 dev eth0 proto kernel scope link src A.B.C.D root:~# ip route show table default default via A.B.C.1 dev eth0 How can I configure routing (or otherwise) such that all forwarded traffic for other hosts on the LAN goes through eth0 but all traffic for the gateway itself goes through the VPN on tun0? Also, since the OpenVPN client changes routing on startup/shutdown, how can I make sure that everything running on the gateway itself loses all network access if the VPN goes down and never goes out eth0.

• Windows 7 Users unable to add Windows 2003 server printers

  - by TravBrack

  Hi there I just rolled out a few Windows 7 x64 machines and ran into this issue where non-admin users are unable to add printers hosted on a windows 2003 server. It works fine on a 2008 server. The issue appears to be with the point and print system. A user will attempt to add the printer, a prompt will come up requiring the user to elevate privileges in order to install a driver, and will fail citing 'access denied'. I found the group policy setting Point and Print Restrictions: When the policy setting is disabled: -Windows Vista computers will not show a warning or an elevated command prompt when users create a printer connection to any server using Point and Print. So I disabled it, verified that the policy was being picked up using rsop, but it still does the same thing. I've also tried the following: Recreating the printers using newer drivers Adding the printer using 32 bit drivers on the 2003 machine, then adding the 64 bit drivers on a Windows 7 machine Adding the printer from a windows 7 machine using print management None of these things work. The security settings are no different than the working printers. Help?

• How much network latency is "typical" for east - west coast USA?

  - by Jeff Atwood

  At the moment we're trying to decide whether to move our datacenter from the west coast to the east coast. However, I am seeing some disturbing latency numbers from my west coast location to the east coast. Here's a sample result, retrieving a small .png logo file in Google Chrome and using the dev tools to see how long the request takes: West coast to east coast: 215 ms latency, 46 ms transfer time, 261 ms total West coast to west coast: 114 ms latency, 41 ms transfer time, 155 ms total It makes sense that Corvallis, OR is geographically closer to my location in Berkeley, CA so I expect the connection to be a bit faster.. but I'm seeing an increase in latency of +100ms when I perform the same test to the NYC server. That seems .. excessive to me. Particularly since the time spent transferring the actual data only increased 10%, yet the latency increased 100%! That feels... wrong... to me. I found a few links here that were helpful (through Google no less!) ... Does routing distance affect performance significantly? How does geography affect network latency? Latency in Internet connections from Europe to USA ... but nothing authoritative. So, is this normal? It doesn't feel normal. What is the "typical" latency I should expect when moving network packets from the east coast <--> west coast of the USA?

• How to set up Git on remote instance using keys from local machine?

  - by Lucas

  I have a setup where I can ssh into my remote server (ie a Google Compute instance) from my local machine. I used to be able to clone, push, and pull from a repository on my remote instance without adding any keys to my remote instance, nor adding any new keys to my repository online (just the public key from my local machine). I believe the remote instance was using the keys from my local machine to authenticate my Git pushes and pulls. However, the system broke when I reinstalled the OS on my local machine. Now I when I try to connect with the Github server from my remote instance, I get the following: Cannot clone: [lucas@ecoinstance]~/node$ git clone [email protected]:lucasExample/test.git test Cloning into 'test'... Permission denied (publickey). fatal: The remote end hung up unexpectedly Cannot push: [lucas@ecoinstance]~/node/nodetest1$ git status # On branch master # Your branch is ahead of 'origin/master' by 1 commit. # nothing to commit (working directory clean) [lucas@ecoinstance]~/node/nodetest1$ git push Permission denied (publickey). fatal: The remote end hung up unexpectedly Additional info: [lucas@ecoinstance]~/node/nodetest1$ ssh-add -l Could not open a connection to your authentication agent. [lucas@ecoinstance]~/.ssh$ ls authorized_keys known_hosts As you can see, I have no keys on my remote instance. I have never had keys on the remote, and it would push and pull just fine until I re-installed my local OS. I can still clone, push, and pull on my local machine, it is just my remote machine that cannot get authentication. My local OS is Ubuntu 14.04 and my remote OS is Debian Wheezy. Any suggestions would be great. I am not sure how to search for this concept where I can authenticate from a remote instance via my local machine, so any reference are appreciated as well.

• Segmentation fault on login to mysql

  - by numberwhun

  Hello everyone! I recently did a fresh install of Ubuntu on my laptop (HP dv7, AMD Dual Core with 4 gigs RAM). I am working on installing my development environment and tools and one of the first things I was working on is getting MySQL installed. The following was my configure statement with options: ./configure --prefix=/usr/local/mysql --with-big-tables --with-unix-socket-path=/usr/local/mysql/tmp/mysql.sock --with-named-curses-libs=/lib/libncurses.so.5.7 After I did the make;make install, I did the post configuration such as setting the root password and installing the mysqld daemon in its rightful place. My issue is when I try to log in to mysql to start using it, the following shows what happens: $ mysql -u root -p Enter password: Welcome to the MySQL monitor. Commands end with ; or \g. Your MySQL connection id is 1 Server version: 5.1.42 Source distribution Segmentation fault I have searched Google extensively, I have searched through the mysql bugs database and I have yet to find anything that matches my issue. Here is the contents of my my.cnf file, in case you want to see it: $ cat /etc/my.cnf [mysqld] basedir=/usr/local/mysql datadir=/usr/local/mysql socket=/usr/local/mysql/tmp/mysql.sock [mysql.server] user=mysql #basedir=/var/lib [client] socket=/usr/local/mysql/tmp/mysql.sock [mysqld_safe] err-log=/usr/local/mysql/logs/mysqld.log pid-file=/var/run/mysqld/mysqld.pid I am really hoping that someone here can tell me what has gone wrong with my installation as I would really love to know. I welcome and look forward to all responses. Thank you in advance! Best regards, Jeff

• virtualbox snapshot size

  - by intuited

  I've started using Windows 7 under VirtualBox on an Ubuntu 10.10 host. I took about 6 snapshots over the course of setting up the VM from the Windows restore image that came with the computer. My installations were more or less limited to windows updates, antivirus, and the VB Guest Additions. I uninstalled much more than I installed. The VM was running for about 24 hours total. The snapshots increased in size at a worrisome rate, even when the machine was idle: the snapshot .vdi file for the period between 11:22 PM and 9:02 AM is 6 gigs in size; during that time very little happened. The other .vdi files are between 0.5 and 3 GB, most between 1 and 2 GB. The corresponding .sav files are between 0.5 and 1 GB. The Internet connection where I was doing this is limited to 30KB/s download, which, constantly saturated, works out to less than 3 GB per 24 hour period. Is this normal? Is there something that can be done to make snapshots more practical? update On starting up the VM again, I've noticed that mscorsvw is using significant processing time. Apparently this process [precompiles .NET assemblies]. This may have been going on during the period when I was taking snapshots, which might explain some of the snapshot size increase. I would be somewhat surprised to learn that this could be responsible for over 10 GB of additional disk usage, or that it would run for roughly 24 hours. Is this possible?

• Remote desktop solution where the desktop sharing party contacts the computer it wants to share with

  - by Kent

  I'm in a situation where I act as a sort of techinical support to my family and less techinically experienced friends. I'm looking for a remote desktop solution where it's possible to setup a "zero-install, double click an icon"-solution where the client computer contacts me so that I may interact with their desktop. The last part is important as the people in need of my help don't know how to configure their router or even the firewall software on their own computer. They are able to click an accept button when asked if a program should be able to make outgoing connections. They have many different kinds of routers, as well as software firewalls, and I rather not deal with the problem of how to connect to them using whatever as well as the actual problem they are having. It must be: Free of charge for non-commercial use. Possible to use it in a mode where the computer wanting to share its desktop should be able to make a connection to my computer. My computer has a DNS name we can use. Compatible with both Windows XP and Windows 7. Independent of a third party server or infrastructure. Explanations of the above: I don't want to spend money on it when I help them for free. If it's free as in freedom, all the better! I guess this boils down to being callable like showdesktopto.exe opscomputer.com where opscomputer.com is my computers DNS name. If that is possible then I can create a shortcut they can use to connect to me when they need help. It's nice if it's possible to specify a password or key file which I can use to authenticate myself, but it's not required. They use the OS which their machine comes installed with. That means Windows XP or 7. I want something which will work in the long run. Using a third party service which might not be available when I need it disqualified such solutions.

• Sendmail in Nexenta core 3.0.1

  - by maximdim

  I'm trying to setup sendmail in Nexenta core 3.0.1 (Solaris based OS). All I want is to be able to send emails from that host - like notifications about failures, cron jobs output etc. Initially Nexenta core doesn't have sendmail so here is what I've done: apt-get install sunwsndmu Now there is a sendmail in /usr/sbin/sendmail. When I try to send email from command line: $mail maxim test . It doesn't give me any error but in log file I see: Dec 20 12:41:08 nas sendmail[12295]: [ID 801593 mail.info] oBKHf8u7012295: from=maxim, size=107, class=0, nrcpts=1, msgid=<201012201741.oBKHf8u7012295@nas>, relay=maxim@localhost Dec 20 12:41:08 nas sendmail[12295]: [ID 801593 mail.info] oBKHf8u7012295: to=maxim, ctladdr=maxim (1000/10), delay=00:00:00, xdelay=00:00:00, mailer=relay, pri=30107, relay=[127.0.0.1] [127.0.0.1], dsn=4.0.0, stat=Deferred: Connection refused by [127.0.0.1] So I guess I need to have SMTP service running. How do I do that in Nexenta? svcs -a | grep sendmail doesn't return anything and # svcadm enable sendmail svcadm: Pattern 'sendmail' doesn't match any instances I'm not married to sendmail so if there are easier ways to achieve y goal I'm open to suggestions as well.

• LogMeIn Hamachi for Linux

  - by tlunter

  So far most of my work using LogMeIn Hamachi has been from either a Mac OS X or Windows system to Windows or a Linux Computer. Recently I purchased a mini computer and have been running Ubuntu Server on it, as my little server. I knew LogMeIn had a Linux client that is command line only, but I often do all my work via command line anyway, so that wasn't an issue. I added my user to the correct local file so that I could run the hamachi daemon without sudo, and was able to connect to LogMeIn's service. I decided to set up my Linux server as a git server as well, and set it up correctly. The thing is, the server is behind my schools firewall and I need to use hamachi to get around that. Since most of the time I was using either Mac or Windows, I never had an issue sshing onto any of my computers since LogMeIn is fully featured for these OSs. From Linux (Arch) though, it seems like the client cannot correctly route to the LogMeIn IPs. I know from Windows I can connect to the Linux computers, both of them. From Linux (Arch) though, I can't connect to my Mac, Windows, or Linux server. It keeps just dropping the connection. I was wondering if there was some configuration that I would need to make for this to work. I understand that it is most likely going to be a static configuration since I assume it has to do with the computer not understanding that 5.*.*.* actually refers to another IP:Port. Has anyone had any experience getting this to work?

• Windows 7 Media Center PC not displaying MKV files properly

  - by David

  Does anyone know why Windows Media Center wouldn't correctly display a 16x9 video? I just upgraded my home-built HTPC from Vista Ultimate (hey, it was a giveaway) to Windows 7 Ultimate - clean install. After that, I installed the Divx7 beta (to get .MKV support) and AC3filter (so I could HEAR the MKV files). Previously, under Vista Ultimate (32 bit), I had Arcsoft's Total Theater Pro for playing Blu-Rays and MKV decoding under Media Center. Now when I play a 720p 16x9 MKV file, I get some 'letterboxing' - like it's halfway between 4x3 and 16x9 - with the aspect ration looking alightly squished as a result. Here's the wierd part. If I use the Media Center connection software in my XBox 360 - it plays perfectly, filling the 16x9 screen edge-to-edge, just like Vista's WMC software USED to. Of course, beats the network up because the XBox goes to the HTPC, the HTPC goes to my WHS machine to fetch the data, it comes back to the HTPC, gets transcoded and streamed back to the Xbox. I'm running the latest drivers for an NVidia card (as fetched by Windows 7). I have no idea WHY this is because if I play "ordinary" (i.s. SD) Divx files that are 16x9, they play just fine, scaled right up to my screen's edges. It puzzles me as to why the same machine that properly converts the bits for the Xbox can't display/scale them properly for the attached display. Mind you, Windows Media Player exhibits the same symptoms. Ideas?

• Get Squid to pass X-Requested-With header

  - by tftd

  I have configured a squid 3.1 proxy server. Everything works great except for the X-Requested-With header. I can't manage to figure out how to pass that header to the site I'm attempting to open via the proxy. This is my current configuration: request_header_access Allow allow all request_header_access Authorization allow all request_header_access WWW-Authenticate allow all request_header_access Proxy-Authorization allow all request_header_access Proxy-Authenticate allow all request_header_access Cache-Control allow all request_header_access Content-Encoding allow all request_header_access Content-Length allow all request_header_access Content-Type allow all request_header_access Date allow all request_header_access Expires allow all request_header_access Host allow all request_header_access If-Modified-Since allow all request_header_access Last-Modified allow all request_header_access Location allow all request_header_access Pragma allow all request_header_access Accept allow all request_header_access Accept-Charset allow all request_header_access Accept-Encoding allow all request_header_access Accept-Language allow all request_header_access Content-Language allow all request_header_access Cookie allow all request_header_access Mime-Version allow all request_header_access Retry-After allow all request_header_access Title allow all request_header_access Connection allow all request_header_access User-Agent allow all request_header_access All deny all #remove all other headers # delete "x-forwarder-for.." headers forwarded_for delete request_header_access Via deny all request_header_access X-Forwarded-For deny all I tried to add this line request_header_access X-Requested-With allow all to the configuration but apparently X-Requested-With is an unknown header name... Apparently I'm missing something?

• SQL Server Instance login issue

  - by reallyJim

  I've just brought up a new installation of SQL Server 2008. I installed the default instance as well as one named instance. I'm having a problem connecting to the named instance from anywhere besides the server itself with any user besides 'sa'. I am running in mixed mode. I have a login/user that has a known username. Using that user/login, I can properly connect when directly on the server. When I attempt to login from anywhere else, I recieve a "Login failed for user ''", with Error 18456. In the log file in the server, I see a reason that doesn't seem to help: "Reason: Could not find a login matching the name provided.". However, that user/login DOES exist, as I can use it locally. There are no further details about the error. Where can I start to find something to help me with this? I've tried deleting and recreating the user, as well as just creating a new one from scratch--same result, locally fine, remotely an error. EDIT: Partially Resolved. I'm now passed the base issue--the clients were trying to connect via the default instance. I don't know why. So, once proper ports were opened in the firewall, and a static port assigned to the named instance, I can now connect--BUT ONLY if I specify the connection as Server,Port. SQLBrowser is apparently not helping/working in this case. I've verified it IS running, and done a stop/restart after my config changes, but no difference yet.

• How can a Postfix/Dovecot(ssl)/Apache/Roundcube(non-ssl) setup leak email addresses?

  - by Jens Björnhager

  I have a linux box email server with Postfix as the MTA, Dovecot as the IMAP server and Apache with Roundcube as webmail. In my /etc/postfix/aliases I have just above a hundred different aliases which makes as many email addresses on my domain. I use one address per website so I easily can shut down spam infested addresses. During the half a year or so that I have had this setup, I have received 3 spam from 2 sources. As I know exactly where I entered this address, it should be easy to pinpoint email leaking websites and services. However, these sources are, according to me, not likely email sellers. And for one of them to sell my email twice? I contacted one of the sources and they are adamant that their system is tight. They suggested the possibility that it is my server that is doing the leaking. So, my question is: How likely is it that my box is leaking email addresses, and how? I don't store fully qualified email addresses anywhere in my system except in my maildir. I use SSL connection to IMAP I do not use https on webmail

• RRAS VPN on windows 2k3 AD, can access rras server only.

  - by nopsax

  I'm setting up a test lab and here is the current configuration: 192.168.86.201 - a windows 2003 machine acting as PDC with AD/DNS/DHCP/WINS. 192.168.86.62 - windows 2003 machine is the RRAS server with IAS, also a file/print server. 192.168.86.6 - gateway/router to internet 192.168.86.21 - Windows XP Workstation Everything works on the internal network, File/Print/AD etc. Whenever a user connects via vpn to the RRAS server remotely using their domain credentials, they are assigned an ip address from the 192.168.86.201 machine along with the wins server address etc. The vpn user can then ping/access resources on the RRAS server, but cannot ping/access resources of any other machines by name or ip. However, if I ping by name, it does resolve to the correct ip address, just no replies. I did notice that on the RRAS server the 'internal' interface gets an ip address of 192.168.86.75 when a remote user connects, and the remote user is assigned, for example 192.168.86.71 . The RRAS server responds on both the .62 and .75 ip addresses. The client also unchecks the 'use remote default gateway option'. Also, I tried connecting a laptop to the physical network, joining the domain, then going remote and dialing the connection before domain login, and everything seems to work, e.g. browse-able shares via network neighborhood. But I can't really join the domain remotely if I cannot access any other resources. I really need to monitor traffic to see whats happening to those packets but won't be able to until this weekend. Any help is appreciated, will provide whatever configurations are needed.

• Why is squid breaking kerberos/NTLM auth?

  - by DonEstefan

  I'm using squid 2.6.22 (Centos 5 Default) as a proxy. Squid seems to break the authentication process for web pages when they require NTLM or Kerberos Auth. I tested with sharepoint 2007 and tried all 3 authentication methods (NTLM, Kerberos, Basic). Accessing the site without squid works in all cases. When I access the same page with squid, then only basic-auth works. Using IE or Firefox desn't make any difference. Squid itself can be used by anybody (no auth_param configured). Its a bit tricky to find solutions online, since most of the topics whirl around auth_param for authenticating users to squid rather than authenticating users to a webpage behind squid. Could anyone help? Edit: Sorry, but my first test was totally screwed up. I tested against the wrong webservers (Memo to myself: always check assumptions before testing). Now I realized that the problem scenario is completely different. Kerberos work for IE Kerberos works for Firefox (after changing "network.negotiate-auth.trusted-uris" in about:config) NTLM works for IE NTLM does NOT work in Firefox (even after changing "network.automatic-ntlm-auth.trusted-uris" in about:config) By the way: The feature that provides NTLM-passthrough in squid is called "connection pinning" and the HTTP header "Proxy-support: Session-based-authentication""

• Are Colocation Cross Connects Worth While

  - by SvrGuy

  We currently operate three clusters of collocated machines in different data centers. Recently, I became aware that our newest data center will offer to cross connect us to a bandwidth provider free of charge. In the past, I never really investigated a cross connect for bandwidth because I figured that the rates would be similar to what we are paying the colo now and that it would reduce our resiliency (because we would only be using one or two carriers for IP, where as the colo uses, say 8 different providers). Then I saw an ad for hurricane electric internet services (http://he.net/cgi-bin/ip_transit_quote) that gave a price for IP transit at $1/Mbs, which is much better than the $30/Mb we pay for the blended bandwidth. What are people out there typically paying for bandwith via cross connect and how hard is to setup? Is my understanding that what you do is open agreemetns with two or three ISPs, cross connect to them and then configure your top of rack router on their network. Can you really get IP transit down to a couple of dollars per megabit per month just by doing the routing yourself? Or, is my understanding of cross connection fundamentally wrong?
