• Unable to connect to shared (iscsitarget) dvd-rw drive on ubuntu karmic box

  - by Develop7

  Intro I have desktop with DVD-RW drive that runs primarily on Linux (namely Ubuntu 9.10). My wife has netbook that rins Windows XP with no cd/dvd drive. There's also LAN through our ADSL modem/router. I've "ported" (actually, I've just grabbed sources and ran dpkg-buildpackage) iscsitarget package from Ubuntu Lucid to Karmic (here are packages), installed it (sudo aptitude install iscsitarget; sudo m-a a-i iscsitarget) and configured it in the following way (/etc/ietd.conf): Target iqn.2020-01.local.develop7-desktop:storage.disc.dvdrw Lun 0 Path=/dev/sr0,Type=blockio #I've skipped commented lines Also, I've opened port 3260 with ufw: $ sudo ufw status | grep 3260 3260 ALLOW 192.168.1.0/24 Problem But (here's the trouble) I still can't connect to this target from Windows box. Microsoft Software iSCSI Initiator screams "Logon failure" upon connect attempt, and, respectively, fails to connect. After unsuccessful connection attempt I've noticed this line in dmesg | tail's output: iscsi_trgt: ioctl(299) invalid ioctl cmd c078690d Question So the question is — what's wrong with my config/iSCSI target/whatever else? Or, in short — what I'm doing wrong? Thanks in advance.

• "Open file location" is broken for Win Live Photo Gallery and Chrome

  - by Arnold Spence

  Symptoms: Windows Live Photo Gallery: Right clicking on an image (.jpg, .png) and selecting the context menu item "Open file location" should open the containing folder in explorer. Instead, I get an error dialog stating "This file does not have a program associated with it for performing this action. Please install a program or, if one is already installed, create an association in the Default Programs control panel." Chrome: After downloading a file (of any type), clicking the down arrow on the download status bar at the bottom and clicking "Show in folder" results in the same error dialog mentioned above. I'm using Windows 7. I'm pretty sure this is a registry entry gone bad but I've been unable to locate any information about this specific problem. It's not a file type association problem as I am not trying to open the files concerned, I'm trying to open an explorer window at the location for the file. I've found a similar issue that somebody had with explorer itself. However, the suggested registry fixes here for "Folder", "Directory" and "Drive" did not solve the problem. Also, If I use the searchbar in explorer to do a search, right click on a file and choose "Open file location", explorer jumps to that location without any trouble. I have not yet identified other programs with this issue.

• How can I debug user mode driver failures in Windows 8

  - by Tom

  I have a 32 GB SD Card. Whenever I insert this card in to my newly upgraded Windows 8 laptop the OS stops responding normally. Metro Apps won't work. The system may or may not log in. Desktop apps may or may not be able to do things. When I remove the card and restart then all is fine. As soon as I put the card back in, the system starts misbehaving again. I've run Windows Update, so I have the latest drivers from Microsoft. This does not occur with the 8 GB cards I have. Unfortunately I only have one 32 GB card, so I can't test with others. From examining the system event log I've determined this is happening due to a user mode driver failure. How can I best debug this issue from here? How can I figure out which driver this is related to? Will there be a Dr. Watson crash dump somewhere? Details - System - Provider [ Name] Microsoft-Windows-DriverFrameworks-UserMode [ Guid] {2E35AAEB-857F-4BEB-A418-2E6C0E54D988} EventID 10110 Version 1 Level 1 Task 64 Opcode 0 Keywords 0x2000000000000000 - TimeCreated [ SystemTime] 2012-10-29T00:51:57.532718300Z EventRecordID 40417 Correlation - Execution [ ProcessID] 1056 [ ThreadID] 3796 Channel System Computer thebrain - Security [ UserID] S-1-5-18 - UserData - UMDFHostProblem [ lifetime] {811E3DC4-FBC6-420B-ABCC-AD7505A36F3B} - Problem [ code] 3 [ detectedBy] 2 ExitCode 3 - Operation [ code] 259 Message 72448 Status 4294967295 Edit 1 So I tried using Debug View from SysInternals (you can get it here: http://technet.microsoft.com/en-us/sysinternals/bb896647.aspx).

• Windows 7 doesn't boot when second hard disk is connected

  - by kenshin9786

  I'm sorry for my bad english on beforehand. I have two hard disks, one SATA and another IDE. I have windows XP and 7 on the SATA one, and Ubuntu on the IDE. Both of them boots and works, bios recognizes them, just works. After I installed Windows 7, and connected the IDE drive, it freezes on "Starting Windows" (the black screen with the Windows logo). I unplug the IDE drive, and it starts normally. Windows XP starts normally on both situations (with or without the IDE one connected), same for Ubuntu (it works with both disks connected or just the IDE where it is). The IDE drive is on good status according to SMART. The IDE is first on boot order. It goes to the Ubuntu's grub first, then by default it goes to the Windows 7 bootloader, and then to XP. I think the problem is not about the bootloader or grub. I just read that it can be solved formatting the "problematic" hard disk because Windows 7 cannot handle so many active partitions or something like that. But that's not an option for me, I don't want to lose my Ubuntu nor have it unbootable. How can I solve this without this consecuences I mentioned? Any help would be appreciated.

• SQL Server 2005 SP3 on Windows 7 - No Management Studio

  - by Mike Thomas

  I've been trying for a day and a half now to get SQL Server 2005, DEV edition, to work on Windows 7, 64 bit prof. I install from the disk, then run SP 3. I get a failure on the Client Components section of the Installation Progress along with this vague message - Product : Client Components Product Version (Previous): 1399 Product Version (Final) : Status : Failure Log File : C:\Program Files\Microsoft SQL Server\90\Setup Bootstrap\LOG\Hotfix\SQLTools9_Hotfix_KB955706_sqlrun_tools.msp.log Error Number : 1712 Error Description : MSP Error: 1712 One or more of the files required to restore your computer to its previous state could not be found. Restoration will not be possible. I've uninstalled all Visual Studio and tried to make this as clean as possible, and have read a lot of the blog posts, but am really at my wits end about this. I am not a DBA, but I use SQL Server all the time when coding and testing apps. Does anyone have any ideas as to where I can get this sorted out? I've been ati this for a long time and have never encountered an installation as bad as this one. Thanks Mike Thomas

• SpamAssassin bayesian score discrepancies

  - by CaptSaltyJack

  This makes my brain hurt. For some reason, SpamAssassin is giving high scores to certain emails, but when I test them on the command line, they get a low score. This one particular email has this in the header: X-Spam-Flag: YES X-Spam-Score: 8.521 X-Spam-Level: ******** X-Spam-Status: Yes, score=8.521 tagged_above=-9999 required=5 tests=[BAYES_99=3.5, BAYES_999=0.2, HTML_MESSAGE=0.001, NO_RECEIVED=-0.001, NO_RELAYS=-0.001, RAZOR2_CF_RANGE_51_100=0.5, RAZOR2_CF_RANGE_E8_51_100=1.886, RAZOR2_CHECK=0.922, URIBL_RHS_DOB=1.514] autolearn=no Yet when I dump the raw email into a file msg and run sudo su amavis -c 'spamassassin -t msg', I get this output: Content analysis details: (3.8 points, 5.0 required) pts rule name description ---- ---------------------- -------------------------------------------------- 1.5 URIBL_RHS_DOB Contains an URI of a new domain (Day Old Bread) [URIs: cliobeads.com] -1.0 ALL_TRUSTED Passed through trusted hosts only via SMTP 0.0 HTML_MESSAGE BODY: HTML included in message -0.0 BAYES_20 BODY: Bayes spam probability is 5 to 20% [score: 0.1855] 1.9 RAZOR2_CF_RANGE_E8_51_100 Razor2 gives engine 8 confidence level above 50% [cf: 100] 0.5 RAZOR2_CF_RANGE_51_100 Razor2 gives confidence level above 50% [cf: 100] 0.9 RAZOR2_CHECK Listed in Razor2 (http://razor.sf.net/) I'm really confused as to why when the email comes in, it gets a completely different score attached to it than when I run spamassassin -t. Is there some other way I should be testing emails? Also, my users have the ability to drag false positives into a folder called "False Positives," and every day a cron job fires off that runs this on every message in every user's folder: sa-learn --dbpath=/var/lib/amavis/.spamassassin --ham /tmp/*-*.eml >/dev/null I ran sudo locate bayes_toks and there's definitely only one bayes DB on the system, in /var/lib/amavis/.spamassassin. I'm clueless, any help would be great and may help restore my sanity!

• Sporadic crash of master-slave MySQL replication process

  - by obarshay

  Hello, I was wondering if someone has experienced this and can perhaps provide some insight into this issue. We have a plan-vanilla MySQL master-slave replication set up. The tables are MyISAM and the master can get quite read/write active. We use the slave instance to perform full daily backups in order to avoid bringing down the master server. The backup process does the following: STOP SLAVE SQL_THREAD mysqlhotcopy all tables START SLAVE SQL_THREAD Every once in a while (once a month or so) the replication breaks with varying error messages indicating a corrupt query or log file. Here's one that happened last night: mysql> show slave status \G *************************** 1. row *************************** Slave_IO_State: Waiting for master to send event Master_Host: server8.propreports.com Master_User: nexus8 Master_Port: 3306 Connect_Retry: 60 Master_Log_File: bin.000045 Read_Master_Log_Pos: 581644327 Relay_Log_File: relay.000086 Relay_Log_Pos: 94131 Relay_Master_Log_File: bin.000045 Slave_IO_Running: Yes Slave_SQL_Running: No Replicate_Do_DB: Replicate_Ignore_DB: Replicate_Do_Table: Replicate_Ignore_Table: Replicate_Wild_Do_Table: Replicate_Wild_Ignore_Table: Last_Errno: 1064 Last_Error: Error 'You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '138070603'£' at line 1' on query.

• Need to get SMTP server on MS Server 2003

  - by Matt Dawdy

  Long story short, client paid networking company to move their website in house. Now I have to figure out how to email out from their website even though they don't have an SMTP server. At least until I install one. Their email is hosted with Gmail right now (the client's domain through Google App for Your Domain). I changed my code to connect as one of their users "[email protected]" and send email. Worked great for about 12 hours. All of a sudden none of the automated emails are going out now, and google is sending the emails back saying that it is a permanent failure and Message Rejected. The link they direct me to, http://mail.google.com/support/bin/answer.py?answer=69585 is telling me that our emails look like spam. They aren't. They are emails we send to out clients about the status of their applications. Seriously, they are NOT spam. So...long story short is out the window, sorry...but I need to get an SMTP server setup inside their domain that I can send emails out of. This thing won't need to receive emails ever, and really only needs 1 email account customercare. What can I do? Will I have to have the networking company open a port in the firewall? Is there one built into Server 2003?

• Reducing IO caused by nginx

  - by glumbo

  I have a lot of free RAM but my IO is always 100 %util or very close. What ways can I reduce IO by using more RAM? My iotop shows nginx worker processes with the highest io rate.

• Cannot send email outside of network using Postfix

  - by infmz

  I've set up an Ubuntu server with Request Tracker following this guide (the section about inbound mail would be relevant). However, while I'm able to send mail to other users within the network/domain, I cannot seem to reach beyond - such as my personal accounts etc. Now I have no idea what is causing this, I thought that all it takes is for the system to fetch mail through our exchange server and be able to deliver in the same way. However, that hasn't been the case. I have found another server setup in a similar fashion (CentOS 5, Request Tracker but using Sendmail), however it is a dated server and whoever's built it has kindly left no documentation on how it works, making it a pain to use that as a reference system! :) At one point, I was told I need to set up a relay between the local server's email add and our AD server but this didn't seem to work. Sorry, I know next to nothing about mailservers, my colleagues nothing about Linux so it's a hard one for me. Thank you!

• Thunderbird alerts when expected email does not arrive

  - by user871199

  I am on Ubuntu 12.04 using Thunderbird as email client. Both are up to date in terms of updates. I have bunch of nightly jobs that do the work and send a status mail. It gets tedious if you keep getting same/similar mails every day so I ended up writing a mail filter rule which causes emails to end up in their respective folders automatically. If things are going ok, I really don't need to read emails. Failure emails are sent to different alias - if the job runs. We recently discovered that one of the job had not run for few days as someone accidentally disabled it. In order to avoid such problems in future, I would like to setup thunderbird in such a way that if I don't get email from given address within given duration, it should alert me. My dream solution is to set up frequency - some jobs do run every 4 hours. Is this possible? Can I setup Thunderbird (preferred) or other email client for reminding me when expected email does not show up. Based on comments and answer I received, here are the reasons why I would like to use Thunderbird. We are already using Thunderbird. It has calender support via plugin, so I suppose someone is already watching time to remind us about the event. May be this another type of event. Additional job is one more failure point, may complicate life if it has to monitor multiple hosts. Additional tools - same thing, one more failure point. Thunderbird can be run across all the platforms we are using - Windows and Ubuntu. It sort of becomes platform independent solution.

• Virtualmin & git integration

  - by weby3456

  I've installed virtualmin on my VPS to manage my websites. It's working perfect and as expected nearly a year now. Recently I wanted to add some features to one of my sites, and I need git integration. I've correctly installed git & gitweb on my server, and I can create repositories and watch them under http://sub.domain.com/git/gitweb.cgi Here is the current relevant directory tree: /home/user/domains/sub.domain.com/public_html/git/ drwxr-sr-x user user . drwxr-x--- user user .. -rw-r--r-- user user git-favicon.png -rw-r--r-- user user git-logo.png -rwxr-xr-x user user gitweb.cgi -rw-r--r-- user user gitweb.css drwxrwx--- apache user reponame.git /home/user/domains/sub.domain.com/public_html/git/reponame.git/ drwxrwx--- apache user . drwxr-sr-x user user .. drwxrwx--- apache user branches -rwxrwx--- apache user config -rwxrwx--- user user description -rwxrwx--- apache user HEAD drwxrwx--- apache user hooks drwxrwx--- apache user info drwxrwx--- apache user objects drwxrwx--- apache user refs But I have some questions: When I'm visiting http://sub.domain.com/git/gitweb.cgi, the owner is listed as 'Apache'. why? how can I change that? Usually, to create a new git repository, I'll do something like: $ mkdir proj $ cd proj $ git init Initialized empty Git repository in /home/user/proj/.git/ // here I'm creating the files or copy them from somewhere else $ git add *.php $ git add README $ git commit -m 'initial version' But after creating the repository in virtualmin, I can find a new dir named 'reponame.git' but not the '.git' dir. When I'm trying to run any git command (e.g. git status) I'm receiving "fatal: This operation must be run in a work tree". How can I work with that repository? Currently I need to explicitly grant access for users to be able to view the repositories via gitweb. How can I make certain repositories public?

• Install self-signed certificate on local server (iis)

  - by ile

  On this page there are instructions on how to create self-signed cert (on apache) and how to install this certificate on server. I found this page (http://www.visualwin.com/SelfSSL/) with instructions on how to create self-signed certificate on windows (iis). I followed instructions and when I type https://myip/myapp (this leads to localhost because I set my router's port forwarding to go to localhost on my pc) this part works. From the first link, the most important part is this: What needs to be installed in IE is actually the Root CA Certificate. In the how-to above, the Root CA Certificate is called ca.crt. Copy this file to the server that is running QuickBooks. The following is for IE6: - Open IE - Tools - Internet Options - Content - Certificates - Trusted Root Certification Authorities Tab - Import, Next, Browse to 'ca.crt' - Next, Next, Finish, Close, OK The part that is missing in second link is that there is no instruction on how to get .crt file, so I tried to get it myself. What I did was following: I opened https://myip/myapp in Firefox and then "This Connection is Untrusted" screen appeared. Then I clicked on "Add Exception" and then below "Certificate Status" I clicked "View". Under the Details tab I clicked on Export and choosed Save as type: "X 509 Certificate (PEM)" and file was saved with .crt extension. Then I opened IE8 and followed above instructions. After opening https://myip/myapp in IE8 I always get warning screen. Does anyone knows what am I doing wrong? Thanks, Ile

• Munin with postgresql 9.2

  - by jreid9001

  I am trying to set up Munin to collect stats on a server with postgresql 9.1 and 9.2 (the server is currently running 9.1, have tested on a fresh VM with 9.2 to rule out some weird problem on the running server. I had to patch some of the plugins for 9.2 due to renamed columns (e.g. procpid to pid), but that's no problem). Munin is installed from the EPEL repos, postgres from the official one. Both up to date. When I try to run munin-node-configure --suggest, I get this output: # The following plugins caused errors: # postgres_bgwriter: # Junk printed to stderr # postgres_cache_: # Junk printed to stderr # postgres_checkpoints: # Junk printed to stderr # postgres_connections_: # Junk printed to stderr # postgres_connections_db: # Junk printed to stderr # postgres_locks_: # Junk printed to stderr # postgres_querylength_: # Junk printed to stderr # postgres_scans_: # Junk printed to stderr # postgres_size_: # Junk printed to stderr # postgres_transactions_: # Junk printed to stderr # postgres_tuples_: # Junk printed to stderr # postgres_users: # Junk printed to stderr # postgres_xlog: # Junk printed to stderr After a lot of searching around, I edited /etc/munin/plugin-conf.d/munin-node and added the following: [postgres*] user postgres This stops munin-node-configure complaining about stderr and lets me add the plugins, but when I telnet to the server on 4949 and try to fetch the stats, I just get "Bad exit". When I run the plugin individually via munin-run (e.g. munin-run postgres_size_ALL ), it works completely fine. Looking at /var/log/munin/munin-node.log, this is the output: Error output from postgres_size_ALL: DBI connect('dbname=template1','',...)failed: could not connect to server: Permission denied Is the server running locally and accepting connections on Unix domain socket "/tmp/.s.PGSQL.5432"? at /usr/share/perl5/vendor_perl/Munin/Plugin/Pgsql.pm line 377 Service 'postgres_size_ALL exited with status 1/0. I am now out of ideas... the socket definitely exists, and pg_hba.conf is set to allow all users/databases from localhost with trust.

• ProCurve 1800 switch issue

  - by user98651

  I recently deployed ProCurve 1800-24G switches in place of some older ProCurve 2424M switches in my network. However, I'm having a serious problem with the switch connected to the router. It seems, every night when our Windows 2008 R2 server (off site) runs a backup to a iSCSI target (on site) [facilitated through a PPTP tunnel] the LAN loses connectivity with the router. To clarify, there is only one router which is connected to the switch affected by this problem. The only way to resolve the issue is to either reboot the router or pull the ethernet cable that goes to the router and plug it back in. During the outage, clients cannot receive DHCP requests, DNS requests, ping, or do anything else with the router in this state. Now, neither the switch or router are configured extensively and the issue only seems to have surfaced with the new switch in place. I have tried a number of things including replacing cables, rebooting and checking the switch configuration (it is literally as basic as you can get at this point-- flat LAN, no trunking). Interestingly, the router shows (accessed externally) no changes in configuration or status during this state but similarly cannot ping or access other hosts on the network. This issue occurs in different stages of backup (ie, different amounts transferred). I've also dumped packets from the switch into WireShark but cannot seem to find any anomaly yet (I'm looking at packets around the time the issue appeared and at the time when I reset the NIC). Any suggestions for what to look for? Ideas on what could be causing this? I'm seeing some transmit/receive errors on the NIC from both the router and switch side but nothing serious when compared to the total packet counts. I'm seriously doubting hardware at this point, as I have tried another switch, different cables, and a different NIC on the router.

• Tell Tomcat to drop requests instead of dying "All threads (150) are currently busy"

  - by Nicolas Raoul

  My Tomcat 6.0.26 sometimes dies saying: SEVERE: All threads (150) are currently busy, waiting. Increase maxThreads (150) or check the servlet status ... then Tomcat shuts down, and users can't access the webapp until I restart Tomcat manually. Some of the threads indeed take a long time to execute, it is by-design, not a thread-gone-wild problem. I know I could increase maxThreads, but that is not a viable solution, because the server might receive requests even more requests. QUESTION: Instead of dying, can I tell Tomcat to just drop requests when maxThreads is reached and the AJP/1.3 backlog is full? Below is my server.xml in any case: <?xml version='1.0' encoding='utf-8'?> <Server port="8005" shutdown="SHUTDOWN"> <Listener className="org.apache.catalina.core.AprLifecycleListener" SSLEngine="on" /> <Listener className="org.apache.catalina.core.JasperListener" /> <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener" /> <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" /> <GlobalNamingResources> <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml" /> </GlobalNamingResources> <Service name="Catalina"> <Executor name="tomcatThreadPool" namePrefix="catalina-exec-" minSpareThreads="100"/> <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443" /> <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" enableLookups="false" useBodyEncodingForURI="true" backlog="150" maxThreads="150" executor="tomcatThreadPool" keepAliveTimeout="5000" connectionTimeout="300000" /> <Engine name="Catalina" defaultHost="localhost" jvmRoute="ecm1"> <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true" xmlValidation="false" xmlNamespaceAware="false"> </Host> </Engine> </Service> </Server>

• Caused by: java.net.SocketException: Software caused connection abort: socket write error

  - by jrishere

  I running JSP on Oracle 11g, Weblogic 10.3.4. I have 2 managed server and a oracle admin server installed. I am encountering an error where intermittently the log file of the 2 managed server and admin server will show java.net.SocketException: Software caused connection abort: socket write error. The application can run for 2 days without showing this error or it can show up a few times in a day. The server load are similar everday. When this error is been encountered, the server will just stop accepting connections and will not be able to access the application. Even if I try to access the application through localhost, I will not be able to access the JSP pages and a 503 http status is shown but then I am able to access the static HTML page. I will not be able to access the Oracle 11g Weblogic admin console page. When I take a look at admin server log, it shows that the managed servers are disconnected from the admin server and vice versa. Magically the application is able to recover by its own and the application is able to access again or I need to restart the server as restarting the service of the application does not work. The FTP connections that the application is connected to are closed as well. I am able to ping to telnet to the server port. The event log doesn't seem to be leaving any information. We did run wireshark to see the packet traffic and it seems that the application port is sending a RST, ACK packet to the load balancer. Any kind help will greatly be appreciated. Should you need more info, feel free to ask me. Thanks in advance.

• Exchange Server 2010: move mailboxes from recoveded and mounted edb to user's mailbox

  - by user36090

  One of our exchange servers crashed, and I am trying to recover the mailboxes. We had 1 exchange 2003 server named "apex" and 1 exchange 2010 server named "2008Enterprise. the exchange 2010 server named "2008Enterprise" crashed. I created a new exchange 2010 server named "Providence". I ran the command on Providence: New-MailboxDatabase -Recovery -Name JBCMail -Server Providence -EdbFilePath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147\Mailbox Database 0579285147.edb" -LogFolderPath "c:\data\Exchange\Mailbox\Mailbox Database 0579285147" this command executed and finished without error I then ran the command: eseutil /p E00 this command was executed from the below directory: c:\data\Exchange\Mailbox\Mailbox Database 0579285147 I then mounted the JBCMail with the mount command note: I do not have my full typed command. Inside my Exchange Management Console (EMC) I can view the new mailbox database named JBCMail. The JBCMail database is show as mounted on the exchange server named Providence. I can see the crashed Exchange server named 2008Exchange. In the EMC the crashed exchange server states the Copy Status under ServerConfiguration-Mailbox is ServiceDown. From here I need to recover three mailboxes The mail boxes are on the apex server. How do I move the mailboxs from apex to Providence? How do I restore the mailboxes from JBCmail mounted database to the user's mailbox? I do not fully understand how to use the Restore-Mailbox command because when I use this command it tries to restore the mailbox to the dead apex server. Restore-Mailbox -ID 'Jason Young' -RecoveryDatabase JBCMail

• Postfix Relay to Office365

  - by woodsbw

  I am trying to setup a Postfix server on a Linux box to relay all mail to our Office365 (Exchange, hosted by Microsoft) mail server, but, I keep getting an error regarding the sending address: BB338140DC1: to= relay=pod51010.outlook.com[157.56.234.118]:587, delay=7.6, delays=0.01/0/2.5/5.1, dsn=5.7.1, status=bounced (host pod51010.outlook.com[157.56.234.118] said: 550 5.7.1 Client does not have permissions to send as this sender (in reply to end of DATA command)) Office 365 requires that the sending address in the MAIL FROM and From: header be the same as the address used to authenticate. I have tried everything I can think of in the config to get this working. My postconf -n: append_dot_mydomain = no biff = no config_directory = /etc/postfix debug_peer_list = 127.0.0.1 inet_interfaces = loopback-only inet_protocols = all mailbox_size_limit = 0 mydestination = xxxxx, localhost.localdomain, localhost myhostname = localhost mynetworks = 127.0.0.0/8 recipient_delimiter = + relay_domains = our.doamin relayhost = [pod51010.outlook.com]:587 sender_canonical_classes = envelope_sender sender_canonical_maps = hash:/etc/postfix/sender_canonical smtp_always_send_ehlo = yes smtp_sasl_auth_enable = yes smtp_sasl_mechanism_filter = login smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd smtp_sasl_security_options = smtp_tls_CAfile = /etc/postfix/cacert.pem smtp_tls_loglevel = 1 smtp_tls_security_level = may smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu) smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache smtpd_use_tls = yes sender_canonical: www-data [email protected] root [email protected] www-data@localhost [email protected] root@localhost [email protected] Also, sasl_passwd is set to the correct credentials (tested them using swaks multiple times.) Authentication works, and sends the message when the from headers are correct (also tested using swaks....which works) The emails are coming from PHP, so I have also tried altering the sendmail path in php.ini to use pass the correct from address via -f So, for some reason, mail coming from www-data and root are not having the from fields rewritten to Office 365's satisfaction, and it won't send the message. Any postfix gurus out there that can help me setup this relay?

• OS X Hard drive recovery

  - by Adam

  I am trying to recover data from a bad Seagate 1TB hard drive in a 2010 iMac. One day the iMac wouldn't boot (stuck at gray screen on startup). I removed the hard drive from the iMac and connected it to a MacBook using a 3.5" HDD to USB adapter. The hard drive wouldn't mount but it did display in Disk Utility that that there were 2 partitions on the disk. I tried to run Disk Warrior and it showed thousands of errors but still wouldn't mount. At this time the hard drive only show one partition in Disk Utility. Next I tried putting the hard drive in a desktop PC and running Spin Rite - which then gave me several division overflow errors (even with running Spin Rite with a newer version of DOS). The SMART status on the drive reports that the drive has had failures and HD Tune referenced the drive had once hit 59 degrees celsius. Disk Utility gives me the following message when running a pair: Error: Disk Utility can’t repair this disk. Back up as many of your files as possible, reformat the disk, and restore your backed-up files. Overall, the hard drive spins up and sounds OK - there are no clicking noises but the hard drive won't mount and displays as a light gray "Macintosh HD" in disk utility. Any tips or advice on how to recover data on this drive would be GREATLY appreciated! Are there any other tools I can try before calling it quits on this drive? Thank you

• Usage of putty in command line from Hudson

  - by kij

  Hi, I'm trying to use putty in command line from an hudson job. The command is the following one: putty -ssh -2 -P 22 USERNAME@SERVER_ADDR -pw PASS -m command.txt Where 'command.txt' is a shell script to execute in the server through SSH. If i launch this command from the Window command prompt, it works, the shell script is executed on the server machine. If i launch a build of the hudson job configured with this batch command, it doesn't work. The build is running... and running... and running.. without doing anything, and i have to stop it manually. So my question is: Is it possible to launch an external programm (i.e. putty) from an hudson job ? ps: i tried SSH plugin but... not a really good plugin (pre/post build, fail status of the commands launched not caught by hudson, etc.) Thanks in advance for your help. Best regards. kij EDIT: These are the build logs: [workspace] $ cmd /c call C:\WINDOWS\TEMP\hudson7429256014041663539.bat C:\Hudson\jobs\Artifact deployer\workspace>putty -ssh -2 -P 22 USER@SERV_ADD -pw PASS -m com.txt Le build a été annulé Finished: ABORTED And the Hudson.err.log file at the same time (after a stop): 3 juin 2010 18:27:28 hudson.model.Run run INFO: Artifact deployer #6 aborted java.lang.InterruptedException at java.lang.ProcessImpl.waitFor(Native Method) at hudson.Proc$LocalProc.join(Proc.java:179) at hudson.Launcher$ProcStarter.join(Launcher.java:278) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:83) at hudson.tasks.CommandInterpreter.perform(CommandInterpreter.java:58) at hudson.tasks.BuildStepMonitor$1.perform(BuildStepMonitor.java:19) at hudson.model.AbstractBuild$AbstractRunner.perform(AbstractBuild.java:601) at hudson.model.Build$RunnerImpl.build(Build.java:174) at hudson.model.Build$RunnerImpl.doRun(Build.java:138) at hudson.model.AbstractBuild$AbstractRunner.run(AbstractBuild.java:416) at hudson.model.Run.run(Run.java:1241) at hudson.model.FreeStyleBuild.run(FreeStyleBuild.java:46) at hudson.model.ResourceController.execute(ResourceController.java:88) at hudson.model.Executor.run(Executor.java:124) My shell script only write "hello" in a "hello.txt" file on the server, and nothing is done.

• Updating modules on VPS hosted under OpenVZ

  - by tertle

  Been trying to install OpenVPN on a VPS but come into a few problems when trying to start the openvpn server: Service deferred error: IPTablesServiceBase: failed to run iptables-restore [status=1]: ['FATAL: Could not load /lib/modules/2.6.18-028stab070.14/modules.dep: No such file or directory', 'FATAL: Could not load /lib/modules/2.6.18-028stab070.14/modules.dep: No such file or directory', 'iptables-restore: line 46 failed']: internet/base:1175,internet/base:752,internet/process:45,internet/process:306,internet/_baseprocess:48,internet/process:775,internet/_baseprocess:60,svc/pp:116,svc/svcnotify:26,internet/defer:238,internet/defer:307,internet/defer:323,sagent/ipts:105,sagent/ipts:39,util/error:52,util/error:32 service failed to start due to unresolved dependencies: set(['user', 'iptables_openvpn']) service failed to start due to unresolved dependencies: set(['user', 'iptables_openvpn']) service failed to start due to unresolved dependencies: set(['iptables_openvpn']) Anyway so after a bit of playing around and some advice, I found that the Linux kernel and modules don't match on my server. uname -r returns 2.6.18-028stab070.14 and ls /lib/modules returns 2.6.18-028stab070.7 The server is running OpenVZ and my container uses Ubuntu 9.10. So my question is, is it possible for me to update my modules on a VPS and if so how would I do this, or is this something I'll need to try get my host to do? Thanks in advance.
