• Best way to attach 96 tb to workstation

  - by user994179

  I'm running a workstation with dual xeon 5690's (12 physical/24 logical cores), 192 gb of ram (ie, maxed-out), Windows 7 64bit, 5 slots for adapter cards, and 1 tb of internal storage, with 5 more internal bays available. I have an app that creates data files totaling about 88 tbs. These are written once every 14 months, and the rest of the time the app only needs to read them; and 95% of the reads are sequential reads of huge chunks of data. I have some control over how big the individual files are, but ideally they would be between 5 and 8 tbs. The app will be reading from only one drive at a time, and the nature of the data is such that if (when) a drive dies I can restore the data to a new disk from tape. While it would be nice to be able to use the fastest drive/controllers available, at this point size matters more than speed. After doing lots of reading, I am leaning toward buying a bunch of cheap 2tb drives and putting them into a bunch of cheap enclosures. All this stuff is going into my home office, so I need to avoid the raised floor/refrigerated approach. My questions: Is the cheap drive/enclosure solution the best one for this situation? Given the nature of the app and the way the data is used, does RAID make sense? If so, which one? For huge sequential reads, would Usb 3.0 and eSata be a wash performance-wise? For each slot available on the workstation, can I hook up an enclosure that can hold multiple drives? Or is it one controller per drive? If I can have multiple drives on one controller, am I essentially splitting the bandwidth (throughput)? For example, if I have a 12 bay enclosure, is the throughput of the controller reduced by a factor of 12? Are there any Windows 7 volume/drive/capacity limits I should be aware of? Thanks

• Dynamic subdomain routing

  - by Nader

  Hi everyone, I asked this question over at stackoverflow, but got very few views: http://stackoverflow.com/questions/2284917/route-web-requests-to-different-servers-based-on-subdomain Perhaps it's more applicable to this crowd. Here it is again for convenience: I have a platform where a user can create a new website using a subdomain. There will be thousands of these, eg abc.mydomain.com, def.mydomain.com . Hopefully if we are successful hundreds of thousands. I need to be able to route these domains to a different IPs to point at a particular app server. I have this mapping in a database right now. What are the best practices and recommended technologies here? I see a couple options: Have DNS setup with a wildcard CNAME entry so that all requests go to a single IP where perhaps two machines using heartbeat (for failover) know how to look up the IP in the database and then do an http redirect to the appropriate app server. This seems clunky and slow to me. Run my own DNS server that can be programatically managed such that when a new site is created a DNS entry is added. We also move sites around to different app servers, so I would need to be able to update DNS entries in close to real time. Thoughts anyone? Thanks. Update2: I've setup external wildcard DNS pointing at an HAProxy web server whose job it is to route requests to backend servers. The mapping is stored in our internal PowerDNS server. Question now is how to get the HAProxy server (or another) to use the value of the internal DNS and not some config file or access list? – Update: Based on some suggestions below, it seems like reverse-proxy server(s) is the way to go. As I'll be rebalancing the domain-server mapping, these need to work instantly and the TTL on a DNS solution could be a problem. Any recommendations on software to use considering this domain-IP data is stored in a DB, and I'll need this to be performant?

• Help me understand Ubuntu user/group permissions.

  - by Bartek

  I'm beginning to deal with more than one user on my system (it's a VPS serving some sites) and I need to make sure I understand how group permissions work. Here's my setup: I have an account named "admin" .. it's basically the primary account that is used for serving most of the sites that I control myself. Now, I added a second account named "Ville" as one of my users wants to be able to administer that site. So, I can do this the easy way and just chown their domains folder under the ville user and viola, they have permission to do whatever they need be and so forth. However, let's say I want to also give the admin user access to the files (modifying and all) .. how can I put both users into the same group and give them both permission? I've tried doing: sudo usermod -a -G admin ville To add the ville into the admin group, but ville still cannot edit files by admin. Permissions for the primary directory for the ville user are read/write for both owner and group, and the current group for the files is admin:admin .. But ville still can't write into the directory. So, what should I be doing here to get this right and secure at the same time? Thank you.

• how do you add an A record for a root domain

  - by nbv4

  this seems really simple, but I can't figure it out. I'm using xname.org since it's free and I own a bunch of domains spread over a few different registrars. The setup I desire is very simple: one A record that points the bare domain name to my server, plus a wildcard CNAME record pointing all subdomains to the same server. So if the user goes to domain.com it will point them to 285.24.435.75, if they go to www.domain, blah.domain.com, or any other sub domain, they'll get sent to 285.24.435.75. All the examples I read on the internet about setting up A records all have the A record set to a subdomain such as www. WWW is deprecated so I want to have noting to do with it. Currently my xname.org zone looks like this: $TTL 86400 ; Default TTL domain.com. IN SOA ns0.xname.org. nbvfour.gmail.com. ( 2010052503 ; serial 10800 ; Refresh period 3600 ; Retry interval 604800 ; Expire time 10800 ; Negative caching TTL ) $ORIGIN domain.com. IN NS ns2.xname.org. IN NS ns0.xname.org. IN NS ns1.xname.org. @ IN A 65.49.73.148 * IN CNAME domain.com The '@' symbol is something that the godaddy domain interface uses to mean "this root domain', but that may have been specefic to that interface and has no meaning here. Before I had a 'www' entry in the A rcords and it worked in the sense that I could ping 'www.domain.com' and it returned a response, but pinging the root domain 'domain.com' returned "no host found".

• Expand disk space on Ubuntu 10.04 (VMWare Guest)

  - by Jason Clawson

  I need to resize the disk space of an ubuntu guest in VMWare Workstation. After using the expand disk utility in vmware workstation, I need to do some linux magic to resize the parition.

• dovecot/postfix: can send & receive via webmin, however squirrel mail and outlook fail to connect

  - by Jonathan

  I have just finished setting up dovecot and postfix on my server (centos 5.5/apache) earlier today. So far I've been able to get email working through webmin (can send/receive to and from external domains). However, attempting to telnet xxx.xxx.xx.xxx 110 returns the following errors: Connected to xxx.xxx.xx.xxx. Escape character is '^]'. +OK Dovecot ready. USER mailtest +OK PASS ********* +OK Logged in. -ERR [IN-USE] Couldn't open INBOX: Internal error occurred. Refer to server log for more information.

Which further logs the following error dovecot: Feb 11 21:32:48 Info: pop3-login: Login: user=, method=PLAIN, rip=::ffff:xxx.xxx.xx.xxx, lip=::ffff:xxx.xxx.xx.xxx, TLS dovecot: Feb 11 21:32:48 Error: POP3(mailtest): stat(/home/mailtest/MailDir/cur) failed: Permission denied dovecot: Feb 11 21:32:48 Error: POP3(mailtest): stat(/home/mailtest/MailDir/cur) failed: Permission denied dovecot: Feb 11 21:32:48 Error: POP3(mailtest): Couldn't open INBOX: Internal error occurred.

Any suggestions or outside thinking on this would be a massive help! I've pretty much exhausted every resource, and tried every suggestion for my dovecot.conf file, but so far nothing seems to work :( I feel like it may be a permissions/ownership issue, but i'm lost as to specifics.

• Utility to LOGICALLY compare two xml files?

  - by Matthew

  Right now we are attempting to build golden configurations for our environment. One piece of software that we use relies on large XML files to contain the bulk of its configuration. We want tot ake our lab environment, catalog it as our "golden configuration" and then be able to audit against that configuration in the future. Since diff is bytewise comparison and NOT logical comparison, we can't use it to compare files in this case (XML is unordered, so it won't work). What I am looking for is something that can parse the two XML files, and compare them element by element. So far we have yet to find any utilities that can do this. OS doesn't matter, I can do it on anything where it will work. The preference is something off the shelf. Any ideas? Edit: One issue we have run into is one vendor's config files will occasionally mention the same element several times, each time with different attributes. Whatever diff utility we use would need to be able to identify either the set of attributes or identify them all as part of one element. Tall order :)

• Multicast hostname lookups on OSX

  - by KARASZI István

  I have a problem with hostname lookups on my OSX computer. According to Apple's HK3473 document it says for v10.6: Host names that contain only one label in addition to local, for example "My-Computer.local", are resolved using Multicast DNS (Bonjour) by default. Host names that contain two or more labels in addition to local, for example "server.domain.local", are resolved using a DNS server by default. Which is not true as my testing. If I try to open a connection on my local computer to a remote port: telnet example.domain.local 22 then it will lookup the IP address with multicast DNS next to the A and AAAA lookups. This causes a two seconds lookup timeout on every lookup. Which is a lot! When I try with IPv4 only then it won't use the multicast queries to fetch the remote address just the simple A queries. telnet -4 example.domain.local 22 When I try with IPv6 only: telnet -6 example.domain.local 22 then it will lookup with multicast DNS and AAAA again, and the 2 seconds timeout delay occurs again. I've tried to create a resolver entry to my /etc/resolver/domain.local, and /etc/resolver/local.1, but none of them was working. Is there any way to disable this multicast lookups for the "two or more label addition to local" domains, or simply disable it for the selected subdomain (domain.local)? Thank you!

• "Server Unavailable" and removed permissions on .NET sites after Windows Update

  - by tags2k

  Our company has five almost identical Windows 2003 servers with the same host, and all but one performed an automatic Windows Update last night without issue. The one that had problems, of course, was the one which hosts the majority of our sites. What the update appeared to do was cause the NETWORK user to stop having access to the .NET Framework 2.0 files, as the event log was complaining about not being able to open System.Web. This resulted in every .NET site on the server returning "Server Unavailable" as the App Domains failed to be initialise. I ran aspnet_regiis which didn't appear to fix the problem, so I ran FileMon which revealed that nobody but the Administrators group had access to any files in any of the website folders! After resetting the permissions, things appear to be fine. I was wondering if anyone had an idea of what could have caused this to go wrong? As I say, the four other servers updated without a problem. Are there any known issues involved with any of the following updates? My major suspect at the moment is the 3.5 update as all of the sites on the server are running in 3.5. Windows Server 2003 Update Rollup for ActiveX Killbits for Windows Server 2003 (KB960715) Windows Server 2003 Security Update for Internet Explorer 7 for Windows Server 2003 (KB960714) Windows Server 2003 Microsoft .NET Framework 3.5 Family Update (KB959209) x86 Windows Server 2003 Security Update for Windows Server 2003 (KB958687) Thanks for any light you can shed on this.

• Laptop hangs on POST and does not finish except on rare occasions

  - by user1049697

  I have an old Toshiba Satellite A100 laptop that hangs on POST when I try to start it. On rare occasions it does finish the POST and boots Windows successfully, but most times it just finishes it partially and continues to hang. I can enter the BIOS though when it has frozen, but I have to open the DVD-drive first for some reason. The keyboard is not quite right either, and I can't navigate the BIOS properly because the arrow keys doesn't work. I tried an external keyboard, but the problem persisted. I have tried to remove the memory, hard drive, and battery to see if any of these were the problem, but it did not solve it. The one logical thing left to do would be to remove the CMOS battery, but the "brilliant" engineers at Toshiba have place it such that a complete disassembly of the machine is necessary. What this all boils down to is basically the question of whether I can "save" this machine and get it to boot properly, or if I should just send it off to recycling. I suspect it might need costly repairs, but I can't bring myself to throw it away before I have made sure it's completely dead.

• Question About mk-table-checksum Results

  - by stevenmusumeche

  Hello, I have 1 master and 2 slaves. I am using MySQL 5.1.42 on all servers. I am attempting to use mk-table-checksum to verify that their data is in sync, but I am getting unexpected results on one of the slaves. First, I generate the checksums on the master like this: mk-table-checksum h=localhost --databases MYDB --tables {$table_list} --replicate=MYDB.mk_checksum --chunk-size=10M My understanding is that this runs the checksum queries on the master which then propagate via normal replication to the slaves. So, no locking is needed because the slaves will be at the same logical point in time when they run the checksum queries on themselves. Is this correct? Next, to verify that the checksums match, I run this on the master: mk-table-checksum --databases MYDB --replicate=IRC.mk_checksum --replicate-check 1 h=localhost,u=maatkit,p=xxxx If there are any differences, I repair the slaves like this: mk-table-sync --execute --verbose --replicate IRC.mk_checksum h=localhost,u=maatkit,p=xxxx After doing all of this, I repaired both slaves with mk-table-sync. However, everytime I run this sequence (after everything has already been repaired), one slave is perfectly in sync but one slave always has a few tables out of sync. I am 99.999% sure that the data on the slaves matches, since I repaired everything and the tables were not even updated on the master between runs of the checksum script. What would cause a few tables to always show out of sync on only one of the slaves? I am stuck. Here is the output: Differences on h=x.x.x.x,p=...,u=maatkit DB TBL CHUNK CNT_DIFF CRC_DIFF BOUNDARIES IRC product 10 0 1 product_id = 147377 AND product_id < 162085 IRC post_order_survey 0 0 1 1=1 IRC mk_heartbeat 0 0 1 1=1 IRC mailing_list 0 0 1 1=1 IRC honey_pot_log 0 0 1 1=1 IRC product 12 0 1 product_id = 176793 AND product_id < 191501 IRC product 18 0 1 product_id = 265041 IRC orders 26 0 1 order_id = 694472 IRC orders_product 6 0 1 op_id = 935375

• Degraded RAID-5 array with lvm2 lost superblock and partition table

• SSD Drive not being recongized in BIOS

  - by chobo2

  Well I bought my first drive Mushkin Chronos 180GB and got it installed in my computer and loaded up. I went to windows 7 and initialized the drive and then I installed "SSDlife Free" and loaded it up and my the SSD drive came up said it was "powered on 3 times"(thought it was odd but then thought maybe some testing???). I then restarted my computer and loaded into Acronis. Went to my SSD drive and make a partition called windows(made a basic logical partition). I then loaded up Norton ghost and wanted to copy my current windows onto the SSD drive on the partition I made found out I could not do it through the recovery disk so I made a backup of my windows drive and wanted to then restore it onto the SSD drive. Came back an hour later when the backup was done. I tried to restore the it on my SSD drive and could not find the partition so I loaded up Acronis again and it did not see it. I then went to the bios and saw only my other hard drive. What I tried Tried uplugging and replugging in both sata and power cables. Tried using the power and sata cable from the working drive and giving it the ones that SSD drive were using. Tried Sata AHCI Mode (Intel ICH9 Southbridge) Tried SATA PORT0-1 NATIVE MODE (Intel ICH9 Southbridge) Nothing worked. Software / hardware Windows 7 ultimate Gigabyte S-Series GA-P35-DS3L Mother board I hope someone has some ideas on why it is not being recognized.

• ProxyPass for specific vhost with mod_rewrite

  - by Steve Robbins

  I have a web server that it set up to dynamically server different document roots for different domains <VirtualHost *:80> <IfModule mod_rewrite.c> # Stage sites :: www.[document root].server.company.com => /home/www/[document root] RewriteCond %{HTTP_HOST} ^www\.[^.]+\.server\.company\.com$ RewriteRule ^(.+) %{HTTP_HOST}$1 [C] RewriteRule ^www\.([^.]+)\.server\.company\.com(.*) /home/www/$1/$2 [L] </IfModule> </VirtualHost> This makes it so that www.foo.server.company.com will serve the document root of server.company.com:/home/www/foo/ For one of these sites, I need to add a ProxyPass, but I only want it to be applied to that one site. I tried something like <VirtualHost *:80> <Directory /home/www/foo> UseCanonicalName Off ProxyPreserveHost On ProxyRequests Off ProxyPass /services http://www-test.foo.com/services ProxyPassReverse /services http://www-test.foo.com/services </Directory> </VirtualHost> But then I get these errors ProxyPreserveHost not allowed here ProxyPass|ProxyPassMatch can not have a path when defined in a location. How can I set up a ProxyPass for a single virtual host?

• Drobo-like linux file server - how do I do it?

  - by John Hunt

  I've been pondering for a long time about how I can set up a server which operates much like the Drobo storage thing. The reasons I don't actually want a drobo is because I've heard scare stories, plus I'd like to do this on the cheap. So ideally I'm looking for something like lvm so I can create a logical volume that spans many hard disks of varying sizes... obviously that only offers redundancy if I put the LV on a raid array (as far as I know..) I have however been reading about technologies such as Microsoft's drive extender which duplicates files at the filesystem level and makes sure that the mirrored files are on a different phyiscal disk.. does anyone know or recommend a filesystem or method like this as it'll hopefully make much better use of the space available than raid ever could. Performance isn't an issue, I'd just really like to make the most of the hard disks I have lying around whilst having a bit of redundancy incase a disk dies. I understand full well that this is no replacement for a backup, but I'll only be storing files of medium importance and using the nas itself as a backup of my main pc and other systems. Thanks in advance! I'm hoping zfs or btrfs or something can do something clever for me :)

• Migrating away from LVM

  - by Kye

  I have an Ubuntu home media server setup with 4.5TB split across a few hard-drives (1x3TB, 2x1TB) and I'm using LVM2 to manage the volumes. I have recently added a 60GB SSD to my server, and I wish to use it to house the 'root' partition of my server (which is currently under the LVM group). I don't want to simply add it to the LVM volume group, because (afaik) there's no way to ensure that the SSD will be used for the root filesystem. If I just throw it at the VG, it may be used to house my media, which would defeat the purpose of having the SSD in the first place. I feel that my only solution is to somehow remove my root partition from the LVM setup and copy it across to the SSD. My boot partition is, of course, not part of the LVM group. My disk setup is as follows: 60GB SSD: EMPTY. 1TB HDD: /boot, LVM space. 1TB HDD: LVM space. 3TB HHD: LVM space. I have a few logical volumes. my root (/), a 'media' volume for my media collection, a backup one for my network backups.etc. Does anyone have any advice as to how to go about this? My end goal is to have the 60GB SSD used for my boot and root partitions, with everything else on the 3TB/1TB/1TB hard-drives.

• How to move Mdadm RAID drive (EBS based) to different AWS Instance

  - by Stanley

  We have a media-rich web application that is hosted on AWS. We have several Web Servers and we have an NFS server. On the NFS server (Linux server) we have several EBS volumes that are mounted and we've used mdadm to implement the different mounted volumes as a single RAID volume. The Web Servers simply access the NFS storage through a mount point. Amazon has now let us know that they will be performing power maintenance on this server in a couple of days time. Since all our media is on here it would render our site unusable for the hours while Amazon is working on it. We want to try and prevent this downtime. I was thinking that we can prevent server downtime by perhaps setting up a new server temporarily and attaching the EBS drives (raid volume) to that server and have our web servers point there during maintenance. This is a very high risk operation since this involves several terabytes of our production data. What would be the safe way to move over our logical raid drive (md0) to a new amazon instance? I was hoping that I could start with building the new server, mounting the ebs volumes and assembling the RAID partition using mdadm --assemble --scan before unmounting from the existing instance so that I can first test that everything works and thus having it mounted on two instances at the same time, but I don't believe that is possible with the way that filesystems work. How do I move a Linux software RAID to a new machine? suggests a way to move drives, but isn't really a cloud-based question. Perhaps there are simpler ways to prevent system downtime with our solution being hosted on the cloud? I have considered taking an EBS snapshot, but that tries to replicate all the many terabytes of mounted storage, so this is not a practical solution. Any ideas?

• IIS 8 URL Redirect on site level

  - by jackncoke

  I am trying to do a simple 301 perm redirect to another url in IIS 8. The end results would be if i navigated to domain2.com i would end up on domain1.com. We are moving from IIS 6 to a new server and have aprox 600+ sites that will be configured on this IIS 8 box. All of these sites run a property CMS and are looking at the same directory for source code. In IIS 6 i would just go to the Home directory tab of each site and check the box that says "Permanent Redirect" and provide a URL. With IIS 8 there is "HTTP Redirect" and this looks like it would do the trick but it is being applied to all the sites in IIS 8. Not on the site level like it use to be in IIS 6. I also looked into URL Rewriting module for IIS 8 but it seems to take rules in the style of a firewall and i am not sure if i could effectly create rules that would cater to 600+ sites. I am looking for the easiest way to have redirects on my site level so that that customers with multiple domains can have there sites redirect to there main domain for seo purposes. I feel like this was so easily achieved in IIS 6 that i must be overlooking something in the new version.

• MSSQL error: consistency-based I/O error - can it be caused by an MSSQL or OS problem?

  - by Philipp Keller

  This is what I saw in the windows error log: SQL Server detected a logical consistency-based I/O error: incorrect checksum (expected: 0x19fedd20; actual: 0x19fed5e3). It occurred during a read of page (1:1764) in database ID 6 at offset 0x00000000dc8000 in file 'D:\mssql\local_repository_pbdiffimport.mdf'. Additional messages in the SQL Server error log or system event log may provide more detail. This is a severe error condition that threatens database integrity and must be corrected immediately. Complete a full database consistency check (DBCC CHECKDB). This error can be caused by many factors; for more information, see SQL Server Books Online. I ran dbcc checkdb which told me I should restore with option REPAIR_ALLOW_DATA_LOSS, so I eventually ran DBCC CHECKDB (my_db_name, REPAIR_ALLOW_DATA_LOSS) WITH NO_INFOMSGS But that resulted in about 2'000 rows being lost. I restored a backup but now I'm afraid this will happen again since we already had a consistency problem in the same database about 2 weeks ago but then it happened in an index (recreated indexes solved the problem). We have investigated the discs - RAID5 looks good, no errors, and also none of the disc-check-utilities have revealed any hardware problem. Can this be caused by OS (Windows Server 2003) or by MSSQL (MSSQL Server 2005)?

• LVM and cloning HDs

  - by jcea

  Using Linux, I have several backup levels. One of them is a periodical sector by sector copy (using dd) of my laptop harddisk to an external USB disk. Yes, I have other backups too, like remote rsync. This approach (the disk dd) is OK when cloning a HDD with no LVM volumes, since I can plug the external disk anytime and mount the partitions simply mounting /dev/sdb* instead of /dev/sda*. Trivial and handy. Today I moved ALL my harddisk (including the /boot) to LVM. Everything works fine. I will stress it for a couple of days, and then I will do a sector by sector copy to my external harddisk. Now I have a problem, I guess. If in the future I plug the external USB HDD to recover any file, the OS will detect a duplicate LVM configuration, with the same name and the same UUID. Even doing a vgrename (which LVM would be renamed, the internal HDD or the external HDD?), the cloned UUID will not change. Is there any command to change name and UUID? Ideally I would clone the HDD and then change the LVM group name and its UUID, but I don't know how to do it. Another related issue would be... In the past I have booted my laptop using the external disk, using the BIOS boot menu and changing GRUB entries manually to boot from /dev/sdb instead of /dev/sda. But now my current GRUB configuration boots directly from a LVM logical volume, something like: set root='(LVM-root)' in my grub.cfg. So... What is going to happen with duplicated volumes? Any suggestion? I guess I could repartition my external harddisk and change backup strategy from dd to rsync, but this disk has windows installed too, and I really would like to have a physical "real" copy.

• Postfix: Modify sender address based on recipient

  - by PJ P

  We have a Postfix server that receives mail from our application servers. Senders are in the form [email protected] (where host.fqdn can vary, depending on source server) and recipients can be internal or external users. Messages going to external users should have the sender changed to [email protected]. I have tried using canonical maps, but since that is handled by the cleanup daemon, before any transport decisions are made, it would affect all sender addresses. I have also tried creating a custom smtp transport with generic mappings and configuring transport_maps to use that custom smtp transport for external domains. However, generic mappings affect both sender and recipient addresses. Lastly, I've tried the following: Create a custom smtpd daemon that specifies sender canonical maps and a unique transport table. Send all externally addressed mail to that custom daemon. Ideally, sender canonical maps would transform the sender address and the unique transport table would relay messages to the internet. However, evidently, only one transport table can be used per Postfix instance. I want to avoid creating an entirely new Postfix instance to accommodate this rewriting. Any suggestions? (and thanks in advance)

• virtual memory commited

  - by vinu

  After a server bounce happens, and after around 40-45 days time period, we receive continuous “Committed Virtual Memory” alerts which indicates the usage of swap space in the magnitude of 4GB This also causes the application to perform very slowly and experience a number of stalled transactions. Server Setup: 4 Tomcat Servers (version 7.0.22) that are load balanced (not clustered) by 2 Apache Servers. And the Apache servers themselves supply static content and routing to these 4 tomcat servers. Java Runtime Version: java version "1.6.0_30" Java(TM) SE Runtime Environment (build 1.6.0_30-b12) Java HotSpot(TM) 64-Bit Server VM (build 20.5-b03, mixed mode Memory Startup Parameters: MEMORY_OPTIONS="-Xms1024m -Xmx1024m -Xss192k -XX:MaxGCPauseMillis=500 -XX:+HeapDumpOnOutOfMemoryError -XX:MaxPermSize=256m -XX:+CMSClassUnloadingEnabled" Monitoring – Wily monitoring is available in all the production servers that monitors key server parameters and sends out configurable alert emails based on pre defined settings. Note: Each of the servers also has two other separate tomcat domains that run different applications Investigated area: There is no Heap Memory Leak and the GC is running fine without any issues over any period of time The current busy thread count corresponds directly to the application usage – weekends and nights have lesser no. of threads compared to business hours ThreadLocal uses a WeakReference internally. If the ThreadLocal is not strongly referenced, it will be garbage-collected, even though various threads have values stored via that ThreadLocal. Additionally, ThreadLocal values are actually stored in the Thread; if a thread dies, all of the values associated with that thread through a ThreadLocal are collected. If you have a ThreadLocal as a final class member, that's a strong reference, and it cannot be collected until the class is unloaded. But this is how any class member works, and isn't considered a memory leak. The cited problem only comes into play when the value stored in a ThreadLocal strongly references that ThreadLocal—sort of a circular reference. In this case, the value (a SimpleDateFormat), has no backwards reference to the ThreadLocal. There's no memory leak in this code. Can anyone please let me know what could be the cause of this and what to be monitored?

• ADFS v.2.0 transitive trust in a federation scenario

  - by masi

  Currently i'm working with ADFS to establish a federated trust between two separated domains. My question is simple: does ADFS v. 2.0 support transitive trust across federated identity providers? I know that ADFS v 1.0 does not, as stated in this document on page 9. But when looking on the claims rules that come with ADFS 2.0 it seems to be possible, as a Microsoft partner confirmed. However: the documentation on this topic is a mess! Simply no ADFS v. 2.0 related statements on this topic that i was able to find (IF you got any documentation on this PLEASE help me out guys!). To be more clear, lets assume this scenario: Federation provider (A) trust federation provider (B) which trusts identity provider (C). So, does (A) trust identities comming from (C) across (B)? Also, if it is possible there are some things that i'm specially interested in: Is it possible to restrict the transitive trust in ADFS in any way? If so, how? How does the transitive trust affect the Issuer and OriginalIssuer properties of the claims? If transitive trust is used together with claims transformations and provider (B) would transform incomming claims from (C) in a way that they are transformed into (new) claims of same type an value, how would this affect the Issuer and OriginalIssuer properties?

• Cannot connect to remote mail server for sending emails in ASP.NET

  - by Dave

  I want to migrate a web application from a Windows Server 2003 to a Windows Server 2008 R2. All works fine except sending emails from the application. If I configure the application to use the smtp server on "localhost" it works, but changing it to the "real" host name (e.g. mail.example.org) no mail is sent. The error message says, that the remote server needs a secure connection or smtp authentication. But since it works when using "localhost" instead of the host name I doubt that this is the problem. Also it's unlikely a problem with the mail server, I also tried it with another one. So for me it seems like the firewall is blocking the outgoing connection to the mail server. I tried to open port 25, but it still did not work. Maybe I just did it the wrong way. Update: For clarifying my setup: I have a Windows Server 2008 R2 with hMailServer installed (set up for some of the hosted domains) For the website I'm talking about I need to use an external mail server (totally different hosting provider) Apparently I was a bit off the track. It seems like it works when using connecting to the local mail server either with the host name "localhost" or "mail.somedomain.com" (while somedomain.com is set up in my mail server). But when using the host name of the external mail server ("mail.externaldomain.com") it seems like it tries to connect to the local server again, although this domain is not set up in the mail server. Thanks to Evan Anderson for the tip to use telnet - why I have not thought of it myself?... :-) Note, the website www.externaldomain.com is hosted on my server but the DNS entries are maintained by the other hosting provider. "externaldomain.com" is the only entry which points to my server all other records (MX, subdomains) are pointing to the other server. So I think the question is now, how do i bring my server to connect to the external mailserver. Do I have to configure this in my mail server or is it a windows server thing?
