• TFS 2012: Backup Plan Fails with empty log file

  - by Vitor

  I have a Team Foundation Server 2012 installation with Power Tools, and I defined a backup plan using the wizard found in the "Database Backup Tools" in the Team Foundation Server Administration Console. I set the backup plan to do a full database backup on Sunday mornings, to another server in the network. I followed the wizard with no problems and the Backup Plan was set successfully. However when the backup runs it returns Error as result and when I go to the log file I only get the header and no further info: [Info @01:00:01.078] ==================================================================== [Info @01:00:01.078] Team Foundation Server Administration Log [Info @01:00:01.078] Version : 11.0.50727.1 [Info @01:00:01.078] DateTime : 11/25/2012 02:00:01 [Info @01:00:01.078] Type : Full Backup Activity [Info @01:00:01.078] User : <backup user> [Info @01:00:01.078] Machine : <TFS Server> [Info @01:00:01.078] System : Microsoft Windows NT 6.2.9200.0 (AMD64) [Info @01:00:01.078] ==================================================================== I can imagine it's a permission problem, but I have no idea where to start ...

• Gnome 3 gdm fails to start after preupgrade from fedora 14 to 15

• Team Foundation Server 2008 - TF220056 Error during installation

  - by David

  I'm attempting to install Team Foundation Server 2008 on a Windows Server 2003 instance that exists under Hyper-V. The SQL Server database itself is held on the root partition of the Hyper-V server and has the Reporting Services installed (so I've solved the TF220059 error already). After hitting "Next " after typing the name of the SQL Server I get this error: --------------------------- Microsoft Visual Studio 2008 Team Foundation Server Setup --------------------------- TF220056: An unrecoverable error occurred while trying to check the status of the Team Foundation database. Installation cannot continue. Check the install log for more details. --------------------------- OK --------------------------- The error log's stack trace makes it look like a bug in the TFS installer itself: [03/22/10,19:14:42] TFSUI: [2] tfsdb.exe: System.IO.IOException: The directory name is invalid.

• Shared firewall or multiple client specific firewalls?

  - by Tauren

  I'm trying to determine if I can use a single firewall for my entire network, including customer servers, or if each customer should have their own firewall. I've found that many hosting companies require each client with a cluster of servers to have their own firewall. If you need a web node and a database node, you also have to get a firewall, and pay another monthly fee for it. I have colo space with several KVM virtualization servers hosting VPS services to many different customers. Each KVM host is running a software iptables firewall that only allows specific ports to be accessed on each VPS. I can control which ports any given VPS has open, allowing a web VPS to be accessed from anywhere on ports 80 and 443, but blocking a database VPS completely to the outside and only allowing a certain other VPS to access it. The configuration works well for my current needs. Note that there is not a hardware firewall protecting the virtualization hosts in place at this time. However, the KVM hosts only have port 22 open, are running nothing except KVM and SSH, and even port 22 cannot be accessed except for inside the netblock. I'm looking at possibly rethinking my network now that I have a client who needs to transition from a single VPS onto two dedicated servers (one web and one DB). A different customer already has a single dedicated server that is not behind any firewall except iptables running on the system. Should I require that each dedicated server customer have their own dedicated firewall? Or can I utilize a single network-wide firewall for multiple customer clusters? I'm familiar with iptables, and am currently thinking I'll use it for any firewalls/routers that I need. But I don't necessarily want to use up 1U of space in my rack for each firewall, nor the power consumption each firewall server will take. So I'm considering a hardware firewall. Any suggestions on what is a good approach?

• How to configure mod_proxy_balancer to gracefully fail under high load

  - by bramp

  We have a system which has one Apache instance in front of multiple tomcats. These tomcats then connect to various databases. We balance the load to the tomcat with mod_proxy_balancer. Currently we are receiving 100 requests a second, the load on the Apache server is quite low, but due to database heavy operations on the tomcats, the load there is roughly 25% (of what I estimate they can handle). In a few weeks there is an event happening and we estimate that our requests will jump significant, maybe by a factor of 10. I'm doing everything I can do reduce the load on our tomcats, but I know we are going to run out of capacity, so I would like to fail gracefully. By this I mean, instead of trying to deal with too many connections which all timeout, I would like Apache to somehow monitor average response time, and as soon as the response time to Tomcat is getting above some threshold, I would like a error page displayed. This means that users who are lucky still get a page rendered quickly, and those who are unlucky get a error page quickly. Instead of everyone waiting far too long for their page, and eventually everyone timing out, and the database being swamped with queries which are never used. Hopefully this makes sense, so I was looking for suggestions on how I could achieve this. thanks

• Mail to Mailenable group sometimes bounces back because it cannot find one of the group members

  - by Stanley

  I am using MailEnable Enterprise Edition 6.53. On one of my PostOffices I have a group address set up with 5 members in the group. Under normal circumstances when someone sends a mail to this group then the mail gets successfully forwarded to all 5 members in the group. However, every now and then when a recipient sends to the group they get a bounce back message from us that the mail could not be delivered because one of the user's addresses was not found on the server. This could happen for any one of the 5 users in the group. The error message looks like: Message could not be delivered. Error was: The email address is not available on this system The following recipient(s) could not be reached: [SF:mydomain.com/my_username] What could be causing this and how do I fix it? Obviously the mailbox DOES exist as, under normal circumstances, when someone mails the group the mail gets delivered successfully and forwarded to all group members. All the mailboxes most definitely DO exist on the system. EDIT: I have done more investigation and I see an error in Windows Event Viewer: MailEnable Database Provider error: 0 FAILURE: (SQLDriverConnect), Module: MEIMAPS.exe; Error: [Microsoft][ODBC SQL Server Driver]Timeout expired This seems to be related to http://forum.mailenable.com/viewtopic.php?p=53157 and http://www.mailenable.com/kb/content/view.asp?ID=ME020535 but the setups in these links use MySQL as a database whereas we use SQL Server. Maybe this shines some new light on the problem?

• Error creating ODBC connection to SQL Server 2008 Express

  - by DavidB

  When creating a System DSN, I get the error: Connection failed: SQLState: '08001' SQL Server Error: 2 [Microsoft][SQL Server Native Client 10.0]Named Pipes Provider: Could not open a connection to SQL Server [2]. Connection failed: SQLState: 'HYT00' SQL Server Error: 0 [Microsoft][SQL Server Native Client 10.0]Login timeout expired I'm running Vista Home Premium 64-bit SP2, and installed SQL Server 2008 Express Advanced without errors. I'll be using the database locally for an app installed on the same PC. I'm able to successfully connect with SQL Server Management Studio using Windows Authentication (my Windows account is a member of local Administrators), and I can successfully create a database with default ownership (defaults to my Windows account). SQL Server Configuration Manager shows that Shared Memory, TCP/IP, and Named Pipes are enabled for SQL Native Client 10.0 Configuration, SQL Native Client 10.0 Configuration (32bit), and SQL Server Network Configuration (SQLEXPRESS). The SQL Server (SQLEXPRESS) and SQL Server Reporting Services (SQLEXPRESS) services are running. When I create a system DSN, my driver choices are SQL server (sqlsrv32.dll 4-10-09), which gives a generic wizard, and SQL Server Native Client 10.0 (sqlncli10.dll 7-10-08), which gives the SQL Server 2008 wizard. I choose the latter. I enter name, description, and have tried both MyPCName and 127.0.0.1 for the server name (browsing turns up nothing). After clicking Next, I leave it at Integrated Windows authentication, and leave Connect to server for additional options checked. After clicking Next, I get the error above. I know it's probably a simple answer, (permission issue?) and I'm a SQL noob, so I appreciate anything that would point me in the right direction. 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?

• What are some techniques to monitor multiple instances of a piece of software?

  - by Geo Ego

  It was recommended that I ask this question here by a member of StackOverflow. I have a piece of self-serve kiosk software that will be running at multiple sites. I'd like to monitor their status remotely. The kiosk application itself is pretty much finished. I am now in the process of creating a piece of software that will monitor all of the kiosks from a central location so that the customer can view particular details remotely (for instance, how many bills are in the acceptor's cash cartridge, what customer is currently logged in, etc.). Because I am in such an early stage of development, my options are quite open. I understand that I'm not giving very many qualifications, but I'd like to try to get a good variety of potential solutions. Some details: Kiosk software is a VB6 app running on Windows Embedded Monitoring software will be run on a modern desktop version of Windows (either XP, Vista, or 7) Database is SQL Server 2008 My initial idea was to develop a .NET app that would simply report the last database transaction for each kiosk at a set interval (say every second or so) but I'd really like for the kiosk software to report its status in real-time. I'm not exactly sure where to begin in terms of what modifications may need to be made to the kiosk software, and what the monitoring software will require. Links to articles on these topics would be most welcome.

• Setting kernel memory for installing postgresql

  - by Matthieu Taymans

  My question is about setting the kernel shared memory for installing postgresql on mac osx 10.6.8. In the readme file of postgresql it is said: Shared Memory PostgreSQL uses shared memory extensively for caching and inter-process communication. Unfortunately, the default configuration of Mac OS X does not allow suitable amounts of shared memory to be created to run the database server. Before running the installation, please ensure that your system is configured to allow the use of larger amounts of shared memory. Note that this does not 'reserve' any memory so it is safe to configure much higher values than you might initially need. You can do this by editting the file /etc/sysctl.conf - e.g. % sudo vi /etc/sysctl.conf On a MacBook Pro with 2GB of RAM, the author's sysctl.conf contains: kern.sysv.shmmax=1610612736 kern.sysv.shmall=393216 kern.sysv.shmmin=1 kern.sysv.shmmni=32 kern.sysv.shmseg=8 kern.maxprocperuid=512 kern.maxproc=2048 Note that (kern.sysv.shmall * 4096) should be greater than or equal to kern.sysv.shmmax. kern.sysv.shmmax must also be a multiple of 4096. Once you have edited (or created) the file, reboot before continuing with the installation. If you wish to check the settings currently being used by the kernel, you can use the sysctl utility: % sysctl -a The database server can now be installed. I'm a real beginner with all this but need to instal postgresql for academic purposes do you know how i can set this kernel shared memory. Won't that be harmful for my system? Thank you in advance. Matthieu

• How to disable mod_security2 rule (false positive) for one domain on centos 5

  - by nicholas.alipaz

  Hi I have mod_security enabled on a centos5 server and one of the rules is keeping a user from posting some text on a form. The text is legitimate but it has the words 'create' and an html <table> tag later in it so it is causing a false positive. The error I am receiving is below: [Sun Apr 25 20:36:53 2010] [error] [client 76.171.171.xxx] ModSecurity: Access denied with code 500 (phase 2). Pattern match "((alter|create|drop)[[:space:]]+(column|database|procedure|table)|delete[[:space:]]+from|update.+set.+=)" at ARGS:body. [file "/usr/local/apache/conf/modsec2.user.conf"] [line "352"] [id "300015"] [rev "1"] [msg "Generic SQL injection protection"] [severity "CRITICAL"] [hostname "www.mysite.com"] [uri "/node/181/edit"] [unique_id "@TaVDEWnlusAABQv9@oAAAAD"] and here is /usr/local/apache/conf/modsec2.user.conf (line 352) #Generic SQL sigs SecRule ARGS "((alter|create|drop)[[:space:]]+(column|database|procedure|table)|delete[[:space:]]+from|update.+set.+=)" "id:1,rev:1,severity:2,msg:'Generic SQL injection protection'" The questions I have are: What should I do to "whitelist" or allow this rule to get through? What file do I create and where? How should I alter this rule? Can I set it to only be allowed for the one domain, since it is the only one having the issue on this dedicated server or is there a better way to exclude table tags perhaps? Thanks guys

• SSO "Portal"

  - by Clinton Blackmore

  Pursuant to my question on alleviating the password explosion, I've contacted some of the services to whom we are paying money to access their websites to ask if we could authenticate our own users, and some of them said yes and send me specs on how to do so. (One of the sites called such a system a page a "portal"; I've never heard the term used in quite that way.) It is simple enough that I am tempted to roll my own. The largest complication is that one site wants us to store a key for every user in our database (and I think the LDAP database makes sense) after their initial login. So, non-trivial, but doable. The nature of these sorts of tasks, I expect, is that if they start out small and simple, they don't end that way. There must be some software that addresses this that is readily extended, surely. In my searching, I've come across: SimpleSAMLphp JOSSO RubyCAS-Server Shibboleth Pubcookie OpenID [Wow, gee. I'd missed some of those in my previous searches! The wikipedia page on Central Authentication Services is useful, and the section on Alternatives to OpenID makes it look like there is a lot of choice.] Can anyone recommend any of these, or suggest ones to avoid? Internally, we are authenticating using Apple's Open Directory [ == OpenLDAP + Kerberos + Password Server (which, I believe, == SAML) ]. As far as extending/tweaking/advanced configuration of a system, I am able to program in Python, C++, can do some basic PHP, and may be able to remember some Java. Looks like I need to pick up Ruby at some point. Addendum: I would also like users to be able to change their passwords over the web (and for certain users to change passwords of other users).

• Program for remove exact duplicate files while caching search results

  - by John Thomas

  We need a Windows 7 program to remove/check the duplicates but our situation is somewhat different than the standard one for which there are enough programs. We have a fairly large static archive (collection) of photos spread on several disks. Let's call them Disk A..M. We have also some disks (let's call them Disk 1..9) which contain some duplicates which are to be found on disks A..M. We want to add to our collection new disks (N, O, P... aso.) which will contain the photos from disks 1..9 but, of course, we don't want to have any photos two (or more) times. Of course, theoretically, the task can be solved with a regular file duplicate remover but the time needed will be very big. Ideally, AFAIS now, the real solution would be a program which will scan the disks A..M, store the file sizes/hashes of the photos in an indexed database/file(s) and will check the new disks (1..9) against this database. However I have hard time to find such a program (if exists). Other things to note: we consider that the Disks A..M (the collection) doesn't have any duplicates on them the file names might be changed we aren't interested in approximated (fuzzy) comparison which can be found in some photo comparing programs. We hunt for exact duplicate files. we aren't afraid of command line. :-) we need to work on Win7/XP we prefer (of course) to be freeware TIA for any suggestions, John Th.

• Why does MOSS sometimes delete an existing user from a site?

  - by Jesse

  I'm experiencing an issue with a MOSS installation. I am using the Site Settings Permissions to add an Active Directory account as a valid user of a site. This entails validating that the user account name is correct via the 'Check Names' button, then giving them 'Contribute' permissions. Once this is done they appear as a user on the 'All People' page. This works fine and the user is able to access the site. At some point in the future (sometimes several days later) the user account is somehow removed as a valid user from the site. This site resides in a test environment so access is pretty well controlled; which has allowed us to rule out someone else going in and removing the user manually. This appears to be something that is being done by the system itself and we have no idea why. We can manually add the user back, but then it will eventually get removed again later. I have an admittedly limited understanding of SharePoint permissions, but I believe that SharePoint stores valid users in a SQL database and I would assume that when dealing with Active Directory accounts it would be storing the user name and probably the SID. It appears that for some reason this record is later getting deleted out of the database, as the users will suddenly disappear from the "All People" page and will start getting "Access Denied: You are not authorized..." messages when trying to access the site. Has anyone seen this behavior before?

• Can't connect to MySQL on CentOS 5 Error 13 - Permission Denied

  - by abszero

  Ok, I have an install of CentOS 5 running as a GuestOS in VirtualBox. The network card for the Cent box is bridged with that of my host OS so that the boxes can see each other. Cent has an IP of 192.168.1.108 and my Host box has an IP of .104. Everything, with regard to networking, seems to be working properly as I can access the Drupal install that is on the Cent box from a web browser on my host box by navigating to http://192.168.1.108 however when I try to configure the database for Drupal through the Drupal install interface I am getting the Can't connect to MySQL error. First I thought this might of been a Firewall issue so I stopped iptables but that had no effect. I thought maybe the user I had setup did not have access to the server so I tried root and that did not work. Searching on the net said that I needed to provide a bind-address parameter to my.cnf so I did that with no change. (As a side note the length of my my.cnf file was MUCH shorter than the ones presented online. In fact under mysqld all I have are datadir, socket, user, and bind-address. Is this normal or should the file be more verbose?) After a few hours of messing with permissions and such I tried using 'localhost' as the value for the database server, from my HOST OS, and the Drupal install kicked off without a problem. So while my issue is resolved I am curious as to why 'localhost' works and why 192.168.1.108 did not? Is there something i need to do to specifically access the MySQL box via the aforementioned IP? Thanks.

• Hiera datatypes wont load in Puppet

  - by Cole Shores

  I have spent a couple of days on this, followed the instructions on http://downloads.puppetlabs.com/docs/puppetmanual.pdf and even the Puppet Training Advanced Puppet manual. When I run a test against it, the results always come back as 'nil' and Im not sure why. I am running Puppet 3.6.1 Community Edition, with Hiera 1.2.1 on SLES 11. My puppet.conf file at /etc/puppet/puppet.conf consists of: [main] # The Puppet log directory. # The default value is '$vardir/log'. logdir = /var/log/puppet # Where Puppet PID files are kept. # The default value is '$vardir/run'. rundir = /var/run/puppet # Where SSL certificates are kept. # The default value is '$confdir/ssl'. ssldir = $vardir/ssl certificate_revocation = false [master] hiera_config=/etc/puppet/hiera.yaml reporturl = http://puppet2.vvmedia.com/reports/upload ssl_client_header = SSL_CLIENT_S_DN ssl_client_verify_header = SSL_CLIENT_VERIFY # certname = dev-puppetmaster2.vvmedia.com # ca_name = 'dev-puppetmaster2.vvmedia.com' # facts_terminus = rest # inventory_server = localhost # ca = false [agent] # The file in which puppetd stores a list of the classes # associated with the retrieved configuratiion.

An # extension indicating the cache format is added automatically. # The default value is '$confdir/localconfig'. localconfig = $vardir/localconfig my /etc/puppet/hiera.yaml consists of: :backends: yaml :yaml: :datadir: /etc/puppet/hieradata :hierarchy: - common - database I have a directory created in /etc/puppet/hieradata and within it contains: /etc/puppet/hieradata/common.yaml :nameserver: ["dnsserverfoo1", "dnsserverfoo2"] :smtp_server: relay.internalfoo.com :syslog_server: syslogfoo.com :logstash_shipper: logstashfoo.com :syslog_backup_nfs: nfsfoo:/vol/logs :auth_method: ldap :manage_root: true and /etc/puppet/hieradata/database.yaml :enable_graphital: true :mysql_server_package: MySQL-server :mysql_client_package: MySQL-client :allowed_groups_login: extranet_users does anyone have any idea what could be causing Hiera to not load the requested values? I have tried even restarting the Master. Thanks in advance, Cole

• Optimizing Disk I/O & RAID on Windows SQL Server 2005

  - by David

  I've been monitoring our SQL server for a while, and have noticed that I/O hits 100% every so often using Task Manager and Perfmon. I have normally been able to correlate this spike with SUSPENDED processes in SQL Server Management when I execute "exec sp_who2". The RAID controller is controlled by LSI MegaRAID Storage Manager. We have the following setup: System Drive (Windows) on RAID 1 with two 280GB drives SQL is on a RAID 10 (2 mirroed drives of 280GB in two different spans) This is a database that is hammered during the day, but is pretty inactive at night. The DB size is currently about 13GB, and is used by approximately 200 (and growing) users a day. I have a couple of ideas I'm toying around with: Checking for Indexes & reindexing some tables Adding an additional RAID 1 (with 2 new, smaller, HDs) and moving the SQL's Log Data File (LDF) onto the new RAID. For #2, my question is this: Would we really be increasing disk performance (IO) by moving data off of the RAID 10 onto a RAID 1? RAID 10 obviously has better performance than RAID 1. Furthermore, SQL must write to the transaction logs before writing to the database. But on the flip side, we'll be reducing both the size of the disks as well as the amount of data written to the RAID 10, which is where all of the "meat" is - thereby increasing that RAID's performance for read requests. Is there any way to find out what our current limiting factor is? (The drives vs. the RAID Controller)? If the limiting factor is the drives, then maybe adding the additional RAID 1 makes sense. But if the limiting factor is the Controller itself, then I think we're approaching this thing wrong. Finally, are we just wasting our time? Should we instead be focusing our efforts towards #1 (reindexing tables, reducing network latency where possible, etc...)?

• How can I configure Cyrus IMAP to submit a default realm to SASL?

  - by piwi

  I have configured Postfix to work with SASL using plain text, where the former automatically submits a default realm to the latter when requesting authentication. Assuming the domain name is example.com and the user is foo, here is how I configured it on my Debian system so far. In the postfix configuration file /etc/main.cf: smtpd_sasl_auth_enable = yes smtpd_sasl_local_domain = $mydomain The SMTP configuration file /etc/postfix/smtpd.conf contains: pwcheck_method: saslauthd mech_list: PLAIN The SASL daemon is configured with the sasldb mechanism in /etc/default/saslauthd: MECHANIMS="sasldb" The SASL database file contains a single user, shown by sasldblistusers2: [email protected]: userPassword The authentication works well without having to provide a realm, as postifx does that for me. However, I cannot find out how to tell the Cyrus IMAP daemon to do the same. I created a user cyrus in my SASL database, which uses the realm of the host domain name, not example.com, for administrative purpose. I used this account to create a mailbox through cyradm for the user foo: cm user.foo IMAP is configured in /etc/imapd.conf this way: allowplaintext: yes sasl_minimum_layer: 0 sasl_pwcheck_method: saslauthd sasl_mech_list: PLAIN servername: mail.example.com If I enable cross-realm authentication (loginrealms: example.com), trying to authenticate using imtest works with these options: imtest -m login -a [email protected] localhost However, I would like to be able to authenticate without having to specify the realm, like this: imtest -m login -a foo localhost I thought that using virtdomains (setting it either to userid or on) and defaultdomain: example.com would do just that, but I cannot get to make it work. I always end up with this error: cyrus/imap[11012]: badlogin: localhost [127.0.0.1] plaintext foo SASL(-13): authentication failure: checkpass failed What I understand is that cyrus-imapd never tries to submit the realm when trying to authenticate the user foo. My question: how can I tell cyrus-imapd to send the domain name as the realm automatically? Thanks for your insights!

• How to configure mod_proxy_balancer to gracefully fail under high load

  - by bramp

  We have a system which has one Apache instance in front of multiple tomcats. These tomcats then connect to various databases. We balance the load to the tomcat with mod_proxy_balancer. Currently we are receiving 100 requests a second, the load on the Apache server is quite low, but due to database heavy operations on the tomcats, the load there is roughly 25% (of what I estimate they can handle). In a few weeks there is an event happening and we estimate that our requests will jump significant, maybe by a factor of 10. I'm doing everything I can do reduce the load on our tomcats, but I know we are going to run out of capacity, so I would like to fail gracefully. By this I mean, instead of trying to deal with too many connections which all timeout, I would like Apache to somehow monitor average response time, and as soon as the response time to Tomcat is getting above some threshold, I would like a error page displayed. This means that users who are lucky still get a page rendered quickly, and those who are unlucky get a error page quickly. Instead of everyone waiting far too long for their page, and eventually everyone timing out, and the database being swamped with queries which are never used. Hopefully this makes sense, so I was looking for suggestions on how I could achieve this. thanks

• OpenLDAP replication fails, "syncrepl_entry: rid=666 be_modify failed (20)"

  - by Pavel

  I've configured a second host to replicate the main LDAP server via syncrepl in the slapd.conf: syncrepl rid=666 provider=ldaps://my-main-server.com type=refreshAndPersist searchBase="dc=Staff,dc=my-main-server,dc=com" filter="(objectClass=*)" scope=sub schemachecking=off bindmethod=simple binddn="cn=repadmin,dc=my-main-server,dc=com" credentials=mypassword When I restart slapd, it writes to /var/log/debug Jun 11 15:48:33 cluster-mn-04 slapd[29441]: @(#) $OpenLDAP: slapd 2.4.9 (Mar 31 2009 07:18:37) $ ^Ibuildd@yellow:/build/buildd/openldap2.3-2.4.9/debian/build/servers/slapd Jun 11 15:48:34 cluster-mn-04 slapd[29442]: slapd starting Jun 11 15:48:34 cluster-mn-04 slapd[29442]: null_callback : error code 0x14 Jun 11 15:48:34 cluster-mn-04 slapd[29442]: syncrepl_entry: rid=666 be_modify failed (20) Jun 11 15:48:34 cluster-mn-04 slapd[29442]: do_syncrepl: rid=666 quitting I've looked into the sources for the return code and found only #define LDAP_TYPE_OR_VALUE_EXISTS 0x14 in include/ldap.h. Anyway, I don't quite get what the error message means. Can you help me debugging this problem and figure out why the LDAP replication doesn't work? I've managed to put a "manual" copy via slapcat and slapadd into the database, but I'd like to sync automatically. UPDATE: "Solved" by removing /var/lib/ldap/* and re-importing the database with slapadd.

• Problems with bash script, mysql inserts and launchd

  - by Armands

  ========= I am developing a automated system, which consists of 3 parts: mysql, bash and launchd. Bash script takes folders of work related stuff, zips, archives and puts info about them into database that is located on a local MAMP server. Everything works as expected when I run the script from terminal. But when I use Launchd to automatically run this script, it functions without errors and it does not put the values into database. I've tried to make logs of returned messages, but the logs end up being empty as the command has run the way it was supposed to. Any help would be appreciated! .plist contents <?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>Label</key> <string>com.adevo.ari.zip</string> <key>ProgramArguments</key> <array> <string>/Volumes/Archive-Plus/B-ARCHIVE-PLUS/ZZ_UTILITY_FOLDER/Compress.sh</string> </array> <key>Nice</key> <integer>1</integer> <key>StartInterval</key> <integer>120</integer> <key>RunAtLoad</key> <true/> </dict> </plist> I made this .plist file just by searching the web.
