• Indefinite hang when restoring SQL 2005 database on a SQL 2008 server in EC2

  - by erinloy

  I'm trying to restore a 25 GB database backup taken from a Windows 2003/SQL 2005 machine to a Windows 2008/SQL 2008 machine in the Amazon EC2 cloud, using a .bak file and the SQL Management Studio. SQL Management Studio reports the restore reaches 100% complete, and then just hangs indefinitely (24+ hours) using a lot of CPU, until I restart the SQL Server service. Upon restart, SQL again uses a lot of CPU activity for what seems to be an indefinite amount of time, but the DB never comes online. Here are some details: - I have created two EBS volumes, one for DATA and one for LOGS, and I have set the default directories in SQL Server to the \DATA and \LOG directory on these respective volumes. (I wonder if the issue could be related to this, but the DB is too big to restore on the root drive.) - I have given the SQL Server user group full access to these directories. - The server can create a new empty test DB in these directories just fine, and can backup and restore the test DB. - I have tried both restoring of a .bak file and attaching directly to copies of the original .mdf/.ldf files, and the result is the same in both cases. - Both the .bak restore and the .mdf/.ldf attach occur from/to the EBS volumes. - I've also tried the above via SQL script, and "WITH RECOVERY", with no difference in the result, just less UI. - The backup contains two full text indexes. - I have to use "WITH MOVE" for most of the files in the backup. - There's nothing wrong with the backup or .mdf/.ldf files, as this works just fine on a Windows 2003/SQL 2005 machine in the Amazon EC2, but not Windows 2008/SQL 2008. - The DB is NOT marked as "Restoring" in the SQL Management Studio - it is just listed as a normal database, but throws errors when I try to do anything with it (expand the object browser tree, view properties, etc.) Any ideas?

• ldap_modify: Insufficient access (50)

  I am running an OpenLDAP 2.4 server that uses the SSL service for communication. It works for lookups. I am trying to add mirror mode replication. So this is the command that I'm executing: ldapmodify -D "cn=myuser,dc=mydomain,dc=com" -H ldaps://myloadbalancer -W -f /etc/ldap/ldif/server_id.ldif Where this is my server_id.ldif: dn: cn=config changetype: modify replace: olcServerID olcServerID: 1 myserver1 olcServerID: 2 myserver2 and this is my cn\=config.ldif in the slapd.d tree of text files: dn: cn=config objectClass: olcGlobal cn: config olcArgsFile: /var/run/slapd/slapd.args olcPidFile: /var/run/slapd/slapd.pid olcToolThreads: 1 structuralObjectClass: olcGlobal entryUUID: ff9689de-c61d-1031-880b-c3eb45d66183 creatorsName: cn=config createTimestamp: 20121118224947Z olcLogLevel: stats olcTLSCertificateFile: /etc/ldap/certs/ldapscert.pem olcTLSCertificateKeyFile: /etc/ldap/certs/ldapskey.pem olcTLSCACertificateFile: /etc/ldap/certs/ldapscert.pem olcTLSVerifyClient: never entryCSN: 20121119022009.770692Z#000000#000#000000 modifiersName: gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth modifyTimestamp: 20121119022009Z But unfortunately I'm getting this: Enter LDAP Password: modifying entry "cn=config" ldap_modify: Insufficient access (50) If I try to specify the config database I get this: ldapmodify -H 'ldaps://myloadbalancer/cn=config' -D "cn=myuser,cn=config" -W -f ./server_id.ldif Enter LDAP Password: ldap_bind: Invalid credentials (49)} Does anyone know how I can add the serverID to the config database so that I can complete the setup of mirror mode?

• Issues with doing a P2V on Exchange 2007

  - by PokermUNKEE

  I shutdown all Exchange services on the physical box and did a convert. Everything converted fine. Server booted up no issues and I could receive email from the outside world with no issues. But I am unable to send emails internally or externally. They just sit in the Outbox. I also disabled the DHCPClient service as I didn't want the server to get an IP address from DHCP when it first came online. It came online with no IP, then I used console to assign the correct static IP address (same one on the physical server) and rebooted. I ran the Exchange Troubleshooting Agent and it gave me the following errors: The value for the '\MSExchangeIS Mailbox\Messages Queued For Submission' counter on server exchange is greater than zero (average value is 8.8) and it appears that 'MSExchangeMailSubmission' is failing to submit messages to at least one computer with the Hub Transport server role installed over the last minute. Found 1 computers with the Hub Transport server role installed in the same Active Directory site as server exchange using local Active Directory site GUID 'ce8a4367-1bf6-4825-9cac-c4e2b115c450'. Check Local Active Directory Site Hub Transport Server Role Health (Mailflow_CheckLocalBhHealth1.1.1.1.1.1.1.1) I have one Exchange server with all the roles on it. Has anyone see this before when doing a convert? Please help :(

• Subversion Apache Ubuntu - Remote Access?

  - by Hollowsteps

  Okay, a couple days ago I built a bare bones kit into a machine. I've been running through tutorials to get it to work and right now I've gotten as far as making it available in my lan, hooray! However, I cannot access the repositories remotely. Any machine on the lan can easily access it through the hostname or, using 'outbound ip/hostname' or 'outbound ip/machine ip'. The machine can be pinged from a remote, non-lan machine and responds. I just can't get anyone into it outside of my lan. I've been trying to figure it out but I'm lost. I'm breaking a few rules and if any of these would be my problem, please indicate. I don't think I have a static IP (However I check my outbound IP whenever I do testing, is that not enough? It has stayed the same for 5+ days) I have not discussed this set-up with my service provider (Does Optimum Online block port 80? If so, can I just switch apache to listen on a different port?) I am in the DMZ of my router. This is what allowed it to be pinged remotely. For security reasons the machine that is in that zone is turned off most of the time until I can get it locked down. Any help would be appreciated, even if it's just a couple of words I could google to understand what I'm doing wrong. Tortoise SVN does not allow access remotely, but it does within the LAN as well.

• Adding an user to samba

  - by JustMaximumPower

  I'm trying to setup some samba shares in my home network on an Ubuntu 12.04 machine. Everything works fine for my user account (max) but I can not add any new user. Every time I try to add new user they can not use the shares. It's likely that the error is very basic to the concept of samba but please don't just tell me to read the docs. I've been trying that for about 2 weeks now. I've set up the server with my user max who can mount transfer and the share max. Than I added the user simon with sudo adduser --no-create-home --disabled-login --shell /bin/false simon because the user should not be able to ssh into the machine. I did an sudo smbpasswd -a simon and set an (samba) password for simon and added an share for simon. I also added simon to transferusers to give him access to the share transfer. But simon can't connect to transfer or simons. ---- output of testparam: ------- Load smb config files from /etc/samba/smb.conf rlimit_max: increasing rlimit_max (1024) to minimum Windows limit (16384) Processing section "[printers]" Processing section "[print$]" Processing section "[max]" Processing section "[simons]" Processing section "[transfer]" Loaded services file OK.

• Use RAID for desktop computer?

  - by NickAldwin

  I'm building a new computer over the summer. I'm fairly competent in computer hardware, and am thus building the computer from scratch. I have everything planned out, but I was wondering if I should consider RAID/what RAID to use. I plan to purchase 2x1TB drives. Currently I'm leaning toward RAID 1 for the redundancy -- I've heard newer super-capacity drives fail more often than one would think, and I don't want to have a problem and lose all my data. What do you think? My mobo supports RAID 0/1/5/10. Is it worth it to use RAID at all, or should I just use a backup service like Mozy? Should I consider RAID 0 instead, for the performance? I'm kind-of going back and forth on this one. Thanks a lot for your help. EDIT: I'd like to avoid the OS drive different from Data drive situation, because that can get frustrating when programs like to store a lot of data in their program files folder. I've lived with that situation before and it gets annoying after a while.

• Confusion about Kerberos, delegation and SPNs.

  - by Vilx-

  I already posted this question on SO, but the nature of it is between programming and server configuration, so I'll re-post it here as well. I'm trying to write a proof-of-concept application that performs Kerberos delegation. I've written all the code, and it seems to working (I'm authenticating fine), but the resulting security context doesn't have the ISC_REQ_DELEGATE flag set. So I'm thinking that maybe one of the endpoints (client or server) is forbidden to delegate. However I'm not authenticating against an SPN. Just one domain user against another domain user. As the SPN for InitializeSecurityContext() I'm passing "[email protected]" (which is the user account under which the server application is running). As I understand, domain users have delegation enabled by default. Anyway, I asked the admin to check, and the "account is sensitive and cannot be delegated" checkbox is off. I know that if my server was running as a NETWORK SERVICE and I used an SPN to connect to it, then I'd need the computer account in AD to have the "Trust computer for delegation" checkbox checked (off by default), but... this is not the case, right? Or is it? Also - when the checkbox in the computer account is set, do the changes take place immediately, or must I reboot the server PC or wait for a while?

• Why am I getting a warning that windows is logging on with a temporary profile to run a task scheduler task?

  - by Dan C

  I am having a strange problem with the Windows Server 2008 Task Scheduler. I have to run a small command-line application every few minutes. This application just executes a quick web service call on the localhost and adds an entry to a log file; so it should not need anything special in terms of permissions. First, I created a new user account "my_scheduler" just for the task. This account is a member of the Users group (not sure what other settings I should turn on/off) and set it's password to not expire. I then create a task to run the application every few minutes. I set it to "Run whether user is logged on or not" and turned on "Do not store password. The task will only have access to local resources" (I did this since it's not hitting anything on the network. I did not turn on "Run with highest privileges" since it does not seem to need them. I set the schedule to "After triggered, repeat every 30 minutes for a duration of 1 day" and "Allow task to be run on demand" (no other settings enabled). However, I notice that in the Event Log, I see a bunch of these warnings whenever the task is run: "Windows cannot find the local profile and is logging you on with a temporary profile. Changes you make to this profile will be lost when you log off." Even though I get the warning, the task is executing (I see the log entries appearing). Another (possibly related) issue is that I also see that it's starting multiple copies of the task (within a few seconds of each other) even though it should only start one. This is also a big problem. Any idea how I can fix this? Thanks in advance, Dan

• Server 2008 R2 Dns Lockup

  - by Richard Maynard

  Hi, We've deployed our first 2008 R2 server on a client site which has replaced their existing 2003 DC. This server provides DNS resolution services to all client machines on that site for general internet usage. Since using the 2008 R2 DNS services we have noticed every couple of days the DNS server starts timing out when requests to certain sites are made (google is the only example I can provide at this time although it seems to be larger sites with problems rather than small - CDN compatiblity issue?). When you restart the DNS Server service then resolution returns to normal... just only for a day or so. Is anybody aware of any significant changes to the DNS server architecture or configuration out of the box in R2 that may explain this intermittent behaviour? I have already tried the fix listed here to no avail: http://weblogs.asp.net/owscott/archive/2009/09/15/windows-server-2008-r2-dns-issues.aspx The following PS command prompt info illustrates the issue: PS C:\Users\Administrator.UK> nslookup Default Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 > www.google.com Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 Non-authoritative answer: Name: www.l.google.com Addresses: 66.102.9.99 66.102.9.104 66.102.9.105 66.102.9.103 66.102.9.147 Aliases: www.google.com > www.google.co.uk Server: s8209001.uk.kingdomfaith.com Address: 10.1.3.4 * s8209001.uk.kingdomfaith.com can't find www.google.co.uk: Server failed Thanks in advance.

• How do I renew an expired Ubuntu OpenLDAP SSL Certificate

  - by Doug Symes

  We went through the steps of revoking an SSL Certificate used by our OpenLDAP server and renewing it but we are unable to start slapd. Here are the commands we used: openssl verify hostname_domain_com_cert.pem We got back that the certificate was expired but "OK" We revoked the certificate we'd been using: openssl ca -revoke /etc/ssl/certs/hostname_domain_com_cert.pem Revoking worked fine. We created the new Cert Request by passing it the key file as input: openssl req -new -key hostname_domain_com_key.pem -out newreq.pem We generated a new certificate using the newly created request file "newreq.pem" openssl ca -policy policy_anything -out newcert.pem -infiles newreq.pem We looked at our cn=config.ldif file and found the locations for the key and cert and placed the newly dated certificate in the needed path. Still we are unable to start slapd with: service slapd start We get this message: Starting OpenLDAP: slapd - failed. The operation failed but no output was produced. For hints on what went wrong please refer to the system's logfiles (e.g. /var/log/syslog) or try running the daemon in Debug mode like via "slapd -d 16383" (warning: this will create copious output). Below, you can find the command line options used by this script to run slapd. Do not forget to specify those options if you want to look to debugging output: slapd -h 'ldap:/// ldapi:/// ldaps:///' -g openldap -u openldap -F /etc/ldap/slapd.d/ Here is what we found in /var/log/syslog Oct 23 20:18:25 ldap1 slapd[2710]: @(#) $OpenLDAP: slapd 2.4.21 (Dec 19 2011 15:40:04) $#012#011buildd@allspice:/build/buildd/openldap-2.4.21/debian/build/servers/slapd Oct 23 20:18:25 ldap1 slapd[2710]: main: TLS init def ctx failed: -1 Oct 23 20:18:25 ldap1 slapd[2710]: slapd stopped.

• Too much memory consumed during TFS automated build

  - by Bernard Chen

  We're running TFS 2010 Standard Edition, and we've set up an automated build to run whenever someone checks in code. We run through all of the automated tests (built with MSTest) as part of the build. We've configured the build to run the tests as a 64-bit process, but the QTAgent.exe that runs the tests grows in memory while the tests are running. It is currently reaching 8GB for the ~650 tests we have, and the process has slowed significantly when we went from 450 tests to 650 tests. When we run all of the tests in the local development environment, memory seems to be freed at least with each TestClass and never exceeds a certain level. The process of running all tests has not increased significantly in the local development environment. Is there a way to configure the build service to free up memory with each Test or each TestClass? With the way things are currently running, the build process gets very slow when we start to run out of memory on the machine. Edit: I found the MSTest invocation in the build log and ran it manually and saw the same behavior of runaway memory. I removed the /publish, /publishbuild, /teamproject, /platform, and /flavor parameters from the invocation of MSTest, in case the test runner was holding onto results until the end, but the behavior didn't change. I ran the same command line on a dev box, separate from the build server, and the memory freed up frequently. It seems there must be something wrong/different about the build server that is causing it to behave different, but I'm stumped where to look. I've looked at qtagent.exe.config, mstest.exe.config, versions of both executables. What else might affect this?

• VSS Post Backup failures for Virtual Server 2005 R2 SP1 virtual machines

  - by califguy4christ

  We've been seeing strange errors with Volume Shadow Copy services on our Virtual Server 2005 R2 SP1 host. It appears to be failing on a strange mountpoint in the C:\WINDOWS\Temp\ folders, which I believe is used by VSS to mount a writeable image file. To summarize: The Microsoft Virtual Server 2005 Writer continually goes into a failed retryable state The Virtual Server log reports errors during the Post Backup phase VSS reports errors backing up a mount point of unknown origins The mount point causes NTFS and ftdisk errors The host is x86 Windows Server 2003 Standard, SP2. The virtual machine is the same. Both use basic disks. Here is the writer state: Writer name: 'Microsoft Virtual Server 2005 Writer' Writer Id: {76afb926-87ad-4a20-a50f-cdc69412ddfc} Writer Instance Id: {78df98e2-bf19-4804-890b-15865efef3bd} State: [11] Failed Last error: Retryable error From the Virtual Server log: Virtual Server - Vss Writer - Event ID: 1035: The VSS writer for Virtual Server failed during the PostBackup phase. The guest shadow copies did not get exposed on the host machine, after mounting all the virtual hard disks of the virtual machine VMACHINE. From the Application log: VSS - None - Event ID: 12290: Volume Shadow Copy Service warning: GetVolumeInformationW( \\?\Volume{fb84bae7-87f5-11dd-9832-001cc4961ca6}\,NULL,0, NULL,NULL,[0x00000000], , 260) == 0x0000045d. hr = 0x00000000. From the System log: Ntfs - Disk - Event ID: 55: The file system structure on the disk is corrupt and unusable. Please run the chkdsk utility on the volume C:\WINDOWS\Temp\ {fb84bae7-87f5-11dd-9832-001cc49.... My current theory is that VSS creates a mount point for an image file of the VHD, then the software panics for some reason, leaving everything in an inconsistent state. Removing the mount point doesn't resolve the problem. All of the other disks check out fine with CHKDSK. There's no exclusion option for VHDs or to turn off online backups. Has anyone seen this kind of thing before or point me in the right direction for getting more information about the mount point and it's origins? I haven't been able to trace what application is creating that mount point.

  I'm having a weird issue with the Exchange Web Services. The operation I'm attempting is pretty simple—pull a user's calendar items for the current week on our internal website. When testing locally, the ews managed API pulls the calendar information just fine. When deployed to the web server (using integrated windows authentication), it chokes. My trace is telling me that access is denied in the Exchange call. Initially, I thought this was a double-hop NTLM permissions issue, but it turns out that the service actually works for some internal users, but not for most. The only thing I can find that the functioning users have in common is that they are blackberry users and I surmise that their exchange permissions are setup differently. Or are their active directory accounts setup differently? I don't know and it's driving me crazy. I surmise that the blackberry app runs some scripts when a user is added to the application, but I'm completely unfamiliar with what may be going on behind the scenes there. So. Is there a way to duplicate the permissions those users enjoy (either AD or Exchange permissions)? And/or how exactly does one fix the double-hop credentials situation?

• New user profile creation error - Windows cannot open *.exe

  - by Jake

  I have a windows 7 laptop with the user "mydomain\boy" that cannot log in to the laptop. the error message is something like "User profile service cannot log in the user boy". I then logged in with the domain admin account "mydomain\admin" and then went to delete the "mydomain\boy" from my computer system properties advance system settings user profiles settings. I also ensure that the user is deleted from control panel user accounts. I then also deleted the user folder c:\users\boy I also checked that the registry at this location HKLM\software\microsoft\windows nt\currentversion\profilelist\ and ensure that there is no entry for boy. I followed http://support.microsoft.com/kb/947215 using the method 3 "fix it for me" but does not seem to do anything. (or i don't know how to use it). AFTER EVERYTHING DONE ABOVE... Everytime i log in with a new user, be it boy, girl or anything other domain account (other than the admin account already created when I first logged in to begin the fix/break), it takes a long time, and when the "preparing desktop" goes away, it starts to exe cannot open error e.g. regsvr.exe etc.. file association problem with exe QUESTION (phew finally..): Please tell me how to fix it? Thanks!

• Unexplained CPU and Disk activity spikes in SQL Server 2005

  - by Philip Goh

  Before I pose my question, please allow me to describe the situation. I have a database server, with a number of tables. Two of the biggest tables contain over 800k rows each. The majority of rows are less than 10k in size, though roughly 1 in 100 rows will be 1 MB but <4 MB. So out of the 1.6 million rows, about 16000 of them will be these large rows. The reason they are this big is because we're storing zip files binary blobs in the database, but I'm digressing. We have a service that runs constantly in the background, trimming 10 rows from each of these 2 tables. In the performance monitor graph above, these are the little bumps (red for CPU, green for disk queue). Once ever minute we get a large spike of CPU activity together with a jump in disk activity, indicated by the red arrow in the screenshot. I've run the SQL Server profiler, and there is nothing that jumps out as a candidate that would explain this spike. My suspicion is that this spike occurs when one of the large rows gets deleted. I've fed the results of the profiler into the tuning wizard, and I get no optimisation recommendations (i.e. I assume this means my database is indexed correctly for my current workload). I'm not overly worried as the server is coping fine in all circumstances, even under peak load. However, I would like to know if there is anything else I can do to find out what is causing this spike? Update: After investigating this some more, the CPU and disk usage spike was down to SQL server's automatic checkpoint. The database uses the simple recovery model, and this truncates the log file at each checkpoint. We can see this demonstrated in the following graph. As described on MSDN, the checkpoints will occur when the transaction log becomes 70% full and we are using the simple recovery model. This has been enlightening and I've definitely learned something!

• Postfix mail server: can't connect via POP/IMAP

  - by MelkerOVan

  I've followed this guide on setting up a mail server on my dedicated server. I've been able to send mails from the php application I'm using and the linux commandline (using telnet, php, etc). The problem is that I cannot connect to the server via IMAP/POP which I've setup using Courier. I've tried using thunderbird but it complains that the username or password is wrong. I doubt it is the username/password but I don't know how to trouble shoot this. Edit: Here's the messages in mail.log: Jan 9 22:43:38 mail authdaemond: received auth request, service=imap, authtype=login Jan 9 22:43:38 mail authdaemond: authmysql: trying this module Jan 9 22:43:38 mail authdaemond: SQL query: SELECT id, crypt, "", uid, gid, home, "", "", name, "" FROM users WHERE id = '[email protected]' AND (enabled=1) Jan 9 22:43:38 mail authdaemond: password matches successfully Jan 9 22:43:38 mail authdaemond: authmysql: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/var/spool/mail/virtual, [email protected], fullname=peter, maildir=<null>, quota=<null>, options=<null> Jan 9 22:43:38 mail authdaemond: authmysql: clearpasswd=<null>, passwd=6SrBcYq65l8QU Jan 9 22:43:38 mail authdaemond: Authenticated: sysusername=<null>, sysuserid=5000, sysgroupid=5000, homedir=/var/spool/mail/virtual, [email protected], fullname=peter, maildir=<null>, quota=<null>, options=<null> Jan 9 22:43:38 mail authdaemond: Authenticated: clearpasswd=peter, passwd=6SrBcYq65l8QU Jan 9 22:43:38 mail imapd: chdir Maildir: No such file or directory

• Webmin / Virtualmin running php as www-data, is locked out of viewing .htaccess and writing

  - by Kirill

  I've asked this on the virtualmin forums, but haven't had any help from there. Recently, "something" happened and it seems that the apache service has gone a bit weird. What it does: it runs all apache traffic as www-data and sometimes spawns the php5-cgi process as www-data, this is a problem because all the domain users own their directories and default permissions don't let www-data write to these folders (file uploads are dead) or read .htaccess (permalinks are broken in wordpress). I've googled this for about a week straight now, tried pretty much everything I could find and achieved nothing. The only thing that I think might actually be the cause of all this is this page: http:// - i.imgur.com/NYW3x.png (got shut down by the spam filter) So I figured if I set it to "default", this might magically start working again, but all it does is "crash" apache (all websites timeout). I figure it's something to do with the "mpm" module or something, but I can't find anything relevant in the settings to modify for it to work. Can someone please point me in the right direction? System info: Webmin version 1.580 Kernel and CPU Linux 2.6.35.4-rscloud on x86_64 Virtualmin version 3.90.gpl GPL Ubuntu 10.04 LTS (Lucid) A couple screenshots of top http://i.imgur.com/U2DTK.png http://i.imgur.com/sNPKs.png

• Problem removing US keyboard layout from input languages

  - by Nazariy

  I'm working on English (UK) version of Windows 7, my second input language is Russian. Since installation of Windows I have removed US keyboard layout and set LEFT ALT+SHIFT as input switcher. Everything was fine until now. Recently I noticed that my switch combination does not always work. I opened language select bar and found there English (US) keyboard layout. I went to settings and found that in General Tab there is only two languages available, US was not listed. I decided to add US layout manually and remove it after. This operation went as expected, US layout disappeared from language bar. But after few hours it appeared again. I started "googling" and found that I'm not alone. On Microsoft forum I found suggestion to remove US layout as I did before and than copy all settings to all profiles. It's look like some service are adding US layout on it's own, but I have no idea which one. Does any one know how to fix this issue?

• How can I resolve Oracle 11g XE connection failure straight after installation?

  - by d3vid

  I have just installed Oracle 11g XE on a Windows 7 VirtualBox VM, using all the default options. "Getting Started" fails When I click on Getting Started I get taken to http://127.0.0.1:8080/apex/f?p=4950 which fails. After some browsing I came across a suggestion to confirm the HTTP port, but I can't get this far, because I can't connect. connect system fails If I select Run SQL command line I get taken to a SQL prompt. I enter connect system and get prompted for a password. I enter the password. I immediately get the following error: ERROR: ORA-01033: ORACLE initialization or shutdown in progress Process ID: 0 Session ID: 0 Serial number: 0 Info: Start database This happens whether or not I run Start database first. (Start database just opens a Windows command prompt window.) Info: Windows services My Oracle services start as follows: Starting the manual services doesn't resolve the problem. Enabling and starting the disabled service doesn't resolve the problem. Is there something I haven't done? How can I resolve this connection error?

• Reverse proxy for mailserver (SMTP + HTTP for web client)

  - by gaqzi

  I'm looking at doing some reverse proxy work for a mail server with corresponding web client. Both servers are running on the same machine, this is not a server with a high load. :) The solution I've discussed with friends is having the mail server/web client on our internal network. Then to put a reverse proxy on the DMZ to service both SMTP and web client HTTP-traffic to the mail server on the internal network. From what I understand this is the recommended secure solution? So far I've thought for the SMTP-proxy part of using postfix which will receive mail, do some spamhause and similar anti-spam measures and if it all checks out, send the mail to the mail server on the inside. The mail server on the inside will send all outgoing mail to the proxy which will then send it out on the Internet. For the web client I'm not sure exactly which software I should be running on the proxy machine, I've been thinking about using Squid -- but that's basically based on the fact that I know squid is a http proxy. The web client data will be sent out over SSL. Reading around some here on Serverfault I've seen other people using Apache with mod_proxy+mod_security for similar situations. Am I thinking correctly for this solution? What software would you guys use and with which modules? Thanks in advance for the help! :)

• How do I identify and fix the cause of transaction log growth on SIMPLE recovery model databases?

  - by Stuart B

  I recently upgraded our SQL Server 2008 installations to service pack 2. One of our databases is on the simple recovery model, but its transaction log is growing extremely fast. The path I'm currently investigating is that we have a transaction somewhere out there stuck in active state. Here is why: select name, recovery_model_desc, log_reuse_wait_desc from sys.databases where name in ('SimpleDB') name recovery_model_desc log_reuse_wait_desc SimpleDB SIMPLE ACTIVE_TRANSACTION When I check my active transactions, I get the following. Note that I installed SP2 and restarted our server on 12/25 at around noonish. select transaction_id, name, transaction_begin_time, transaction_type from sys.dm_tran_active_transactions transaction_id name transaction_begin_time transaction_type 233 worktable 2010-12-25 12:44:29.283 2 236 worktable 2010-12-25 12:44:29.283 2 238 worktable 2010-12-25 12:44:29.283 2 240 worktable 2010-12-25 12:44:29.283 2 243 worktable 2010-12-25 12:44:29.283 2 245 worktable 2010-12-25 12:44:29.283 2 62210 tran_sp_MScreate_peer_tables 2010-12-25 12:45:00.880 1 55422856 user_transaction 2010-12-28 16:41:56.703 1 55422889 SELECT 2010-12-28 16:41:57.303 2 470 LobStorageProviderSession 2010-12-25 12:44:30.510 2 Note that according to the documentation a transaction_type of 1 means read/write, and 2 means read-only. So, my line of thinking is that the trans_sp_MScreate_peer_tables transaction is stuck for some reason and holding up transaction log truncation. Is this a plausible scenario? Correct me if my line of thinking is off, as I'm not a SQL Server expert. If this is correct, how do I erase that transaction so that my transaction log is truncated as usual?
