  • Convention location for JAR files for a LaunchDaemon on OS X?

    - by Barry Wark
    I'm setting up a Hudson build slave on an OS X machine. I'm using launchd to start the slave using the following plist in `/Library/LaunchDaemons/': <?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>KeepAlive</key> <true/> <key>Label</key> <string>org.hudson-ci.jnlpslave</string> <key>ProgramArguments</key> <array> <string>/usr/bin/java</string> <string>-jar</string> <string>/Users/Shared/Hudson/slave.jar</string> <string>-noCertificateCheck</string> <string>-jnlpUrl</string> <string>file:///Users/Shared/Hudson/slave-agent.jnlp</string> </array> <key>RunAtLoad</key> <true/> </dict> </plist> I'm currently putting the slave.jar and slave-agent.jnlp files in /Users/Shared/Hudson but this seems like an unnecessarily user-visible location. What's the convention? Where should I be putting these JARs for a daemon?

  • Allow members of a group to be unlocked by a specific account on AD

    - by JohnLBevan
    Background I'm creating a service to allow support staff to enable their firecall accounts out of hours (i.e. if there's an issue in the night and we can't get hold of someone with admin rights, another member of the support team can enable their personal firecall account on AD, which has previously been setup with admin rights). This service also logs a reason for the change, alerts key people, and a bunch of other bits to ensure that this change of access is audited / so we can ensure these temporary admin rights are used in the proper way. To do this I need the service account which my service runs under to have permissions to enable users on active directory. Ideally I'd like to lock this down so that the service account can only enable/disable users in a particular AD security group. Question How do you grant access to an account to enable/disable users who are members of a particular security group in AD? Backup Question If it's not possible to do this by security group, is there a suitable alternative? i.e. could it be done by OU, or would it be best to write a script to loop through all members of the security group and update the permissions on the objects (firecall accounts) themselves? Thanks in advance. Additional Tags (I don't yet have access to create new tags here, so listing below to help with keyword searches until it can be tagged & this bit editted/removed) DSACLS, DSACLS.EXE, FIRECALL, ACCOUNT, SECURITY-GROUP

  • auth user and exec a node app only with apache?

    - by Blame
    I couldn't find an answer on the web and I'm trying for days now so I hope that someone with more experience with apache can help me out. Iam writing an web editor and the user should be able to edit a file that is on the server in a directory the user has access to. The problem Iam facing is that I need to authenticate against the system users (shadow/passwd). So the user should be able to login whith a system account and then the node app which does all the logic should be started with the users rights. I hope to get this working without any additional script and only with Apache. I found out two things: I can use mod_auth_pam to authenticate the user There is a mod called suEXEC which can exec the node app with a specified user The problem is that I have to hard code which user is used by suEXEC but I want to decide when the user logs in. Is there any way to authenticate a user against the shadow/passwd and then exec a prog with the users rights? I dont want to run the node app as root and the user should only be able to access his own files. Any help would be appreciated! Thanks, Kodak

  • sudo or acl or setuid/setgid?

    - by Xavier Maillard
    for a reason I do not really understand, everyone wants sudo for all and everything. At work we even have as many entries as there are way to read a logfile (head/tail/cat/more, ...). I think, sudo is defeating here. I'd rather use a mix of setgid/setuid directories and add ACL here and there but I really need to know what are the best practices before starting up. Our servers have %admin, %production, %dba, %users -i.e many groups and many users. Each service (mysql, apache, ...) has its own way to install privileges but members of the %production group must be able to consult configuration file or even log files. There is still the solution to add them into the right groups (mysql...) and set the good permission. But I do not want to usermod all users, I do not want to modify standards permissions since it could change after each upgrade. On the other hand, setting acls and/or mixing setuid/setgid on directories is something I could easily do without "defacing" the standard distribution. What do you think about this ? Taking the mysql example, that would look like this: setfacl d:g:production:rx,d:other::---,g:production:rx,other::--- /var/log/mysql /etc/mysql Do you think this is good practise or should I definetely usermod -G mysql and play with standard permissions system ? Thank you

  • How do I setup a secondary incoming mail server?

    - by abrahamvegh
    I currently have a server running Debian 6, with postfix and dovecot handling email. This server hosts email for a number of domains and users, so I use MySQL as my backing store for users and forwardings and everything related. Currently, this server is the only server listed in an MX record for all of the domains it serves. I would like to create a secondary server that would be listed in the DNS with a lower priority (e.g. current primary server is priority 5, secondary would be priority 10), so that in the event that I need to reboot the primary server, or otherwise make it unavailable, the secondary server would receive email, and hold it until the primary server came back up, at which point it would deliver any held email to the primary server. I do not need the secondary server to function as a backup sending server. Users would never need to see the secondary server, they would simply not lose incoming emails if the primary server is down, and they would be unable to send or receive until the primary came back up. How would I go about doing this? I would like to use the same software if they can handle this task, because I’m already familiar with managing them.

  • Windows preventing running of Telnet client

    - by palswim
    At first, I had issues because Windows 7 doesn't install the Telnet client by default (also, SuperUser has a thread). So, after installing it (and restarting, like Windows asked, though completely unnecessary), I opened a command prompt, and went to run my new Telnet program. I enter telnet, and receive: C:\Users\[USER]>telnet 'telnet' is not recognized as an internal or external command, operable program or batch file. "That's odd," I think to myself. So, in Windows explorer, I navigate to \Windows\System32 and see telnet.exe sitting in that folder. If I double-click on the executable file, the Telnet command prompt opens for me without a problem. So, I return to my Windows Command Prompt, and enter: C:\Users\[USER]>\Windows\System32\telnet.exe '\Windows\System32\telnet.exe' is not recognized as an internal or external command, operable program or batch file. And then (grep comes from cygwin): C:\Users\ryan\Desktop>dir \Windows\System32 | grep telnet Nothing. I've disabled UAC and have no idea why my Command Prompt is lying to me. Anyone experience something similar? To recap: In Windows 7, I have installed Telnet and can see it in my System32 folder, but cannot run it via a Command Prompt.

  • Exchange 2010: Send emails via STMP with custom From address to outside the domain

    - by marsze
    The requirement(s): (1) Connect to Exchange via STMP and (2) basic authentication and send emails with a (3) custom From address to (4) recipients outside the domain. I was able to get (1) - (3) working. I created a dedicated receive connector for this task and configured it like this: Permissions: ms-Exch-SMTP-Accept-Any-Recipient (for authenticated users) ms-Exch-SMTP-Accept-Authoritative-Domain-Sender (for authenticated users) ms-Exch-SMTP-Accept-Any-Sender (for authenticated users) Authentication: TLS Basic Authentication (without TLS) Exchange Server Authentication However, I'm still struggeling with (4): I can send with "fake" From addresses to recipients inside the domain. Also, I can send with the original From address to recipients outside the domain. Can you tell me what I'm missing, to configure Exchange to send emails with changed From addresses to recipients outside the domain? (Or is this even possible at all?) Thanks. UPDATE I have to correct myself: it seems to be working after all. There must be some issue with the mailbox I used for testing. It turned out it's working with other external mailboxes. However, I still have no idea what was different there... Anyways, you can take this as a documentation on how to configure Exchange in such a way ;)

  • Server format & Reinstall while keeping Server & domain ID

    - by Chris
    Hi Everyone, I want to reinstall my 2008 R2 server from scratch, due to multiple Active Dir issues. I have only 1 server running AD and a spare machine to use if necessary. Is there a way to save just the user accounts and the domain SID, so that I can start with a clean server that uses the same name as before? I can reassign file security, but I do not want to have to rejoin all the users to a new domain. Also all users are mapped to folders on the server. What I hope to do is a clean install of the server without having to mess with the users machines. can someone please tell me the procedure to accomplish this? any help appreciated! Thanks guys, but I could be here all day telling you every error I am getting. can we please keep this to the question of how to do a reinstall and keep the same SID? I just want to start over without having to rejoin all the clients to a new domain. Is there such a tool that can backup the Server SID and the AD domain name so that I could restore them, without restoring any other data? I might not be using the correct terminology here, but hopefully you understand what I am asking. Thanks

  • How can I sync Access databases and keep them up-to-date?

    - by user327472
    I have an Access database on my server. We split it up and use the front-end database for search data and adding new records or reports in local computer. If we update or add a new record, that writes to the back-end of database. I want to use this database in the other building with other servers. Also, those servers have no direct connection. How can I sync both back-end databases to keep the database data up to date? These details may be useful: It's a big amount of data - about 25,750 client records. I guess there are more than 25 tables at 80 MB.

  • Mysql Query - That Is Returning Blatanty Incorrect Result

    - by user866190
    I am building a VPS node that is running Ubuntu 10.10LTS, Apache2, Mysql 5.1 and php5. I could not log in to my website admin through the browser, even though I am using the correct login details. So I logged in from the command line to check the results. When I run this query I get expected results: mysql> select * from users; +----+----------+-----------------------+----------+ | id | username | email | password | +----+----------+-----------------------+----------+ | 1 | myUserName | [email protected] | myPassword | +----+----------+-----------------------+----------+ And the same goes for this query: mysql> select * from users where id = 1; +----+----------+-----------------------+----------+ | id | username | email | password | +----+----------+-----------------------+----------+ | 1 | myUserName | [email protected] | myPassword | +----+----------+-----------------------+----------+ 1 row in set (0.00 sec) But when I run this query I get this 'unexpected response': mysql> select * from users where username = 'myUserName' and password = 'myPassword'; Empty set (0.00 sec) I am not sure why this is happening. Any help would be greatly appreciated. BTW.. I will be encrypting the user details but for now I just want to get it set up. Please help, Thanks

  • Is 40+ Logons on Exchange 2003 per user normal?

    - by cbsch
    Hello! We've had a problem at work where users sometimes randomly can't connect to exchange. I've found out that it's because they reached the limit of 32 concurrent logons. I increased the maximum allowed connections by adding the key "Maximum Allowed Sessions Per User" in HKLM\SYSTEM\CurrentControlSet\Services\MSExchangeIS\ParametersSystem. But I'm not sure if this is a real good fix. Looking at the logons some users has as many as 15 logons with the exact same logon time. I know for sure that Outlook 2007 does this, as I was watching them while a user connected with Outlook after a restart on the Exchange service. Every user also has an iPhone connected to exchange, I don't know if these cause the same thing. Is this normal? Could there be a bug in the software? (The Outlook 2007 has nothing configured, except added the user, pure vanilla installs). The users are mobile, and when Outlook generates up to 15 connection every time it connects, and I've read (no sources, sorry) that Outlook doesn't time out connections before 2 hours. I might have to set this number real high to prevent it from being a problem.

  • What kind of server configuration is best for a chatting app? [closed]

    - by mohabitar
    I'm just now starting to go deeper into the world of cloud hosting and databases, and am getting overwhelmed by how deep this information goes. It's all a little too much to consume in a short amount of time. I get a lot of pricing information, but I'm unable to determine what that means to me. I'm making what you might compare to an email app. Users can send messages to one another. I just don't understand, out of the several options, what would be ideal for an app like this, where users would be constantly sending and receiving text data. With Amazon DynamoDB, I have to specify a pre-defined throughput with number of reads and writes per second. Sure I can just type 50, but I'm not exactly sure what 50 writes per second represents. I'm trying to determine what would be the most cost efficient solution, and I want to know what a throughput of 50 reads/writes/second compares to. Is that a high number? What is a good throughput number for a message sending app with say 50,000 daily users? I'm just providing specific numbers so I can understand what these throughput numbers represent. 100 transactions/second to me seems like a small number since I'm not familiar with this stuff, so I'm just looking to bring everything in context. What would 100 read/write/second be useful for? Are there any average example values available? And I'm not sure what each service is good for. For a message sending app, is there any reason I'd want to choose say Amazon DynamoDB over Google App Engine? Any insight would be greatly appreciated.

  • Must have local user to authenticate Samba to AD?

    - by Phil
    I've got a CentOS 5.3 server with Samba running. I've joined this server to my domain in the hopes of allowing AD users some access to my Samba shares. I've found that this works, but only as long as the AD username that I'm trying to authenticate with is also a local user on the server. In other words, if I'm trying to access a share, and try to authenticate with the AD username "joe", I get errors unless I create a user named 'joe' on the server. I don't have to create a matching password or anything....the local user's password is always blank, so I do know that the authentication is actually happening against the AD. Here's my smb.conf file: [global] workgroup = <mydomain> server string = <snip> netbios name = HOME security = ADS realm = <mydomain.com> password server = <snip> auth methods = winbind log level = 1 log file = /var/log/samba/%m.log [amore] path = /var/www/amore browseable = yes writable = yes valid users = DOMAIN\user1 DOMAIN\user2 DOMAIN\user3 DOMAIN\user4 I would assume that my kerberos settings are fine, as I've joined the domain and can use wbinfo to see users and groups. However, I can provide that info if necessary. Anyone have any ideas?

  • Hide/Unhide rows based on more than one cell value

    - by Mike
    Please help me I am using the following code to hide rows if cell values are 0: Private Sub Worksheet_Calculate() Dim LastRow As Long, c As Range Application.EnableEvents = False LastRow = Cells(Cells.Rows.Count, "I").End(xlUp).Row On Error Resume Next For Each c In Range("I9:I48") If c.Value = 0 Then c.EntireRow.Hidden = True ElseIf c.Value > 0 Then c.EntireRow.Hidden = False End If Next On Error GoTo 0 Application.EnableEvents = True End Sub It works perfectly, but I would like for the code to also check column K (the same range K9:K48) if both cells in a row are 0 then the row must be hidden. How can I change the code to do this?

  • OSX server setup suggestions

    - by Tom
    I am looking into the possibility to setup an OSX server for my employees, and would like some input on what is the best approach to meet my needs, and perhaps some suggestions if I am moving in the wrong direction. I am thinking of a Mac Mini OSX server, and are not sure if my needs will be met, and what possibilities are out there. I want these capabilities: - Groups/Users managed on server - Shared folders and private folders for users/groups - Access to activated services - Server hosting software for the users (developing tools ++) - Similar to Windows Terminal Server - Virtual desktop environment (both local and over internet/VPN) - Possible to access trough Mac and Windows The reason I am looking at OSX server is that my employees almost only work in OSX environment, and I want to offer the capabilities to logon to the server trough some kind of terminal software, and have full access to their work OSX environment and software on their mac or pc, from anywhere they might be. Instead of having to have multiple setups and need for spending alot of time installing and setting up needed software on every client. This is a small business, where some work on local network, and others from the internet, preferably trough VPN. But a terminal server solution, that are fast and easy to manage would be perfect for our needs. So if anyone have any experience with a similar setup, please let me know what you did, and your experiences with your setup.

  • how to export VARs from a subshell to a parent shell?

    - by webwesen
    I have a Korn shell script #!/bin/ksh # set the right ENV case $INPUT in abc) export BIN=${ABC_BIN} ;; def) export BIN=${DEF_BIN} ;; *) export BIN=${BASE_BIN} ;; esac # exit 0 <- bad idea for sourcing the file now these VARs are export'ed only in a subshell, but I want them to be set in my parent shell as well, so when I am at the prompt those vars are still set correctly. I know about . .myscript.sh but is there a way to do it without 'sourcing'? as my users often forget to 'source'. EDIT1: removing the "exit 0" part - this was just me typing without thinking first EDIT2: to add more detail on why do i need this: my developers write code for (for simplicity sake) 2 apps : ABC & DEF. every app is run in production by separate users usrabc and usrdef, hence have setup their $BIN, $CFG, $ORA_HOME, whatever - specific to their apps. so ABC's $BIN = /opt/abc/bin # $ABC_BIN in the above script DEF's $BIN = /opt/def/bin # $DEF_BIN etc. now, on the dev box developers can develop both ABC and DEF at the same time under their own user account 'justin_case', and I make them source the file (above) so that they can switch their ENV var settings back and forth. ($BIN should point to $ABC_BIN at one time and then I need to switch to $BIN=$DEF_BIN) now, the script should also create new sandboxes for parallel development of the same app, etc. this makes me to do it interactively, asking for sandbox name, etc. /home/justin_case/sandbox_abc_beta2 /home/justin_case/sandbox_abc_r1 /home/justin_case/sandbox_def_r1 the other option i have considered is writing aliases and add them to every users' profile alias 'setup_env=. .myscript.sh' and run it with setup_env parameter1 ... parameterX this makes more sense to me now

  • 5 year old server upgrade

    - by rizzo0917
    I am looking to upgrade a server for a web app. Currently the application is running very sluggish. We've made some adjustments to mysql (that's another issue in itself) and made some adjustments so that heaviest quires get run on a copy of the database on another server was have as a backup, however this will not last that much longer and we are looking to upgrade. Currently the servers CPUs are (4) Intel(R) XEON(TM) CPU 2.00GHz, with 1 gig of ram. The database is 442.5 MiB, with about 1,743,808 records. There are two parts of the program, the one, side a, inserts and updates most of the data. Side b, reads the data and does some minor updates. Currently our biggest day for side a are 800 users (of 40,000 users all year) imputing the system. And our Side b is currently unknown, however we have a total of 1000 clients. The system is most likely going to cap out at 5000 side b clients, with about a year 300,000 side a users. The current database is 5 years old, so we can most likely expect the database to grow pretty rapidly, possibly double each year (which we can most likely archive older records if it comes to that). So with that being said, should we get a server for each side of the app, side a being the master, side b being the slave, any updates made on side b are router to side a. So the question is should i get 2 of these or 1. 2 x Intel Nehalem Xeon E5520 2.26Ghz (8 Cores) 12GB DDRIII Memory 500GB SATAII HDD 100Mbps Port Speed And Naturally I would need to have a redundant backup so it could potentially be 4 of them.

  • Linux SFTP and many local user accounts, limits with mount --bind?

    - by user123428
    I am in the process of building a solution to handle many developers (possibly hundreds) to work on their files via sftp, each one Jailed in their home directory. For our particular needs, we have a samba mount point that contains all of the users home directories. I have started developing the following solution and hit some walls: - I have configured a Ubuntu Lucid Server as sftp server. - In order to jail the user in their home directory (without allowing them the browse a directory up and seeing all the other users folders) I am using mount --bind and not a symbolic link (also some ftp clients don't really work with sym links). - The user accounts are local unix user accounts on the sftp server (not using a directory service or anything) that have an empty home folder created on the local machine, then I use mount --bind to bind the empty folder to the actual users home directory on the samba share. With this solution I am hitting a couple of problems, in the case of a server reboot, all the mount --binds are lost because they are not written in fstab. Then I have read somewhere that the maximum amount of entries in fstab are 400 (which does not really help us). I have thought of a solution of writing something that stores the mounts in a text file as a backup and on server reboot, run the script that re mounts. I am just really unsure about this whole process and was wondering if anyone has any insight on possibly a better solution for SFTP? (not FTP)

  • Image annotation with Inkscape, Pointer and explanation for objects in picture

    - by None
    I need straight paths with end markers for associating text to parts of the image. For better readability, it needs to be high-contrast, i.e. a white line with black outline. Stroke to path will create a group of a box and a circle from the line with end marker. This makes placement of the markers more difficult, as with the node tool it is just a matter of dragging the end nodes of a line segment. I will try to place the markers as line for now and only finally converting them to an outline.

  • What is the potential for a FUSE mount to destabilize a Linux server?

    - by 200_success
    I'm a sysadmin for a multi-user server, where students in our department have shell accounts. One of our users has requested that we install sshfs on it. I'm debating whether it would be wise to install sshfs as suggested. My main concern is whether a FUSE mount could make our server less reliable. In my experience, bad things can happen to servers when an NFS server suddenly becomes unavailable — the load average shoots up, and you might not be able to unmount it cleanly, to the point where a hard reboot might be necessary. If a FUSE-mounted server suddenly disappears, how hard might it be to clean up the mess? Are there any other likely catastrophes or gotchas I should consider? At least with NFS, only root can mount, and we can choose to mount NFS servers that we consider to be reasonably reliable. Let's assume that our users have no hostile intentions, but might do stupid things accidentally. Also, I'm not really worried about the contents of the filesystems they might mount, since our users already have shell access and can copy anything they want to their home directory.

  • Windows XP to remote server 2008 R2 shares - awful response times

    - by nick3216
    I have a network infrastructure of Windows XP clients (a mix of XP and 64-bit XP), that are accessing a network share on a Windows 2008 R2 server. Whenever users type the address of a folder into the address bar of Windows Explorer it's as snappy at determining the contents of the current folder and presenting them to you in the address bar as if you're working on a local drive. But if you open one of the subfolders users get the animated red torch and 'Searching for items...' dialog, typically for 45 seconds. Similarly when using the open folder dialog to try and select a subfolder on this share it takes, on average, 45 seconds for the dialog to expand each node and show the subfolders of each node. Also, while the Explorer instance accsesing the network share is running slowly users notice that the performance of all other Explorer windows suffers. So while Explorer is searching for files on the network share they can't switch to another task and navigate around their local drive using Explorer because it's now as slow as a dead dog at accessing anything. Are there any settings we can change which will improve the performance accessing network shares?

  • Why are perfectly legitamate pages on my website registering in google Webmasters as 404?

    - by christian
    I have seen this question asked several times here, but never clearly answered. I suspect it has something to do with my .htaccess file: # BEGIN WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteBase / RewriteRule ^index\.php$ - [L] RewriteCond %{REQUEST_FILENAME} !-f RewriteCond %{REQUEST_FILENAME} !-d RewriteRule . /index.php [L] </IfModule> # END WordPress <IfModule mod_rewrite.c> RewriteEngine On RewriteRule ^moreinfo/(.*)$ http://www.kgstiles.com/moreinfo$1 [R=301] RewriteRule ^healthsolutions/(.*)$ http://www.kgstiles.com/healthsolutions$1 [R=301] RewriteRule ^(.*)\.html$ $1/ [R=301] RewriteRule ^(.*)\.htm$ $1/ [R=301] </IfModule> when I check the url without a forward slash at the end, it registers as 404 (even though it renders fine in a browser), but when I write it without the forward slash at the end, it renders 200 OK, but if I try to take off the forward slash with the htaccess file, the browser gives me a 310 error (too many redirects) you can see the 404 and 310 with this url: http://www.kgstiles.com/pureplantessentials.html which redirects to http://www.kgstiles.com/pureplantessentials/ (which is a 404), so what is a solution and why might this be registering as a 404? Any Help is appreciated! (I'm using wordpress btw)

  • MVVM for Dummies

    - by Martin Hinshelwood
    I think that I have found one of the best articles on MVVM that I have ever read: http://jmorrill.hjtcentral.com/Home/tabid/428/EntryId/432/MVVM-for-Tarded-Folks-Like-Me-or-MVVM-and-What-it-Means-to-Me.aspx This article sums up what is in MVVM and what is outside of MVVM. Note, when I and most other people say MVVM, they really mean MVVM, Commanding, Dependency Injection + any other Patterns you need to create your application. In WPF a lot of use is made of the Decorator and Behaviour pattern as well. The goal of all of this is to have pure separation of concerns. This is what every code behind file of every Control / Window / Page  should look like if you are engineering your WPF and Silverlight correctly: C# – Ideal public partial class IdealView : UserControl { public IdealView() { InitializeComponent(); } } Figure: This is the ideal code behind for a Control / Window / Page when using MVVM. C# – Compromise, but works public partial class IdealView : UserControl { public IdealView() { InitializeComponent(); this.DataContext = new IdealViewModel(); } } Figure: This is a compromise, but the best you can do without Dependency Injection VB.NET – Ideal Partial Public Class ServerExplorerConnectView End Class Figure: This is the ideal code behind for a Control / Window / Page when using MVVM. VB.NET – Compromise, but works Partial Public Class ServerExplorerConnectView Private Sub ServerExplorerConnectView_Loaded(ByVal sender As Object, ByVal e As System.Windows.RoutedEventArgs) Handles Me.Loaded Me.DataContext = New ServerExplorerConnectViewModel End Sub End Class Figure: This is a compromise, but the best you can do without Dependency Injection Technorati Tags: MVVM,.NET,WPF,Silverlight

  • Processing Email in Outlook

    - by Daniel Moth
    A. Why Goal 1 = Help others: Have at most a 24-hour response turnaround to internal (from colleague) emails, typically achieving same day response. Goal 2 = Help projects: Not to implicitly pass/miss an opportunity to have impact on electronic discussions around any project on the radar. Not achieving goals 1 & 2 = Colleagues stop relying on you, drop you off conversations, don't see you as a contributing resource or someone that cares, you are perceived as someone with no peripheral vision. Note this is perfect if all you are doing is cruising at your job, trying to fly under the radar, with no ambitions of having impact beyond your absolute minimum 'day job'. B. DON'T: Leave unread email lurking around Don't: Receive or process all incoming emails in a single folder ('inbox' or 'unread mail'). This is actually possible if you receive a small number of emails (e.g. new to the job, not working at a company like Microsoft). Even so, with (your future) success at any level (company, community) comes large incoming email, so learn to deal with it. With large volumes, it is best to let the system help you by doing some categorization and filtering on your behalf (instead of trying to do that in your head as you process the single folder). See later section on how to achieve this. Don't: Leave emails as 'unread' (or worse: read them, then mark them as unread). Often done by individuals who think they possess super powers ("I can mentally cache and distinguish between the emails I chose not to read, the ones that are actually new, and the ones I decided to revisit in the future; the fact that they all show up the same (bold = unread) does not confuse me"). Interactions with this super-powered individuals typically end up with them saying stuff like "I must have missed that email you are talking about (from 2 weeks ago)" or "I am a bit behind, so I haven't read your email, can you remind me". TIP: The only place where you are "allowed" unread email is in your Deleted Items folder. Don't: Interpret a read email as an email that has been processed. Doing that, means you will always end up with fake unread email (that you have actually read, but haven't dealt with completely so you then marked it as unread) lurking between actual unread email. Another side effect is reading the email and making a 'mental' note to action it, then leaving the email as read, so the only thing left to remind you to carry out the action is… you. You are not super human, you will forget. This is a key distinction. Reading (or even scanning) a new email, means you now know what needs to be done with it, in order for it to be truly considered processed. Truly processing an email is to, for example, write an email of your own (e.g. to reply or forward), or take a non-email related action (e.g. create calendar entry, do something on some website), or read it carefully to gain some knowledge (e.g. it had a spec as an attachment), or keep it around as reference etc. 'Reading' means that you know what to do, not that you have done it. An email that is read is an email that is triaged, not an email that is resolved. Sometimes the thing that needs to be done based on receiving the email, you can (and want) to do immediately after reading the email. That is fine, you read the email and you processed it (typically when it takes no longer than X minutes, where X is your personal tolerance – mine is roughly 2 minutes). Other times, you decide that you don't want to spend X minutes at that moment, so after reading the email you need a quick system for "marking" the email as to be processed later (and you still leave it as 'read' in outlook). See later section for how. C. DO: Use Outlook rules and have multiple folders where incoming email is automatically moved to Outlook email rules are very powerful and easy to configure. Use them to automatically file email into folders. Here are mine (note that if a rule catches an email message then no further rules get processed): "personal" Email is either personal or business related. Almost all personal email goes to my gmail account. The personal emails that end up on my work email account, go to a dedicated folder – that is achieved via a rule that looks at the email's 'From' field. For those that slip through, I use the new Outlook 2010  quick step of "Conversation To Folder" feature to let the slippage only occur once per conversation, and then update my rules. "External" and "ViaBlog" The remaining external emails either come from my blog (rule on the subject line) or are unsolicited (rule on the domain name not being microsoft) and they are filed accordingly. "invites" I may do a separate blog post on calendar management, but suffice to say it should be kept up to date. All invite requests end up in this folder, so that even if mail gets out of control, the calendar can stay under control (only 1 folder to check). I.e. so I can let the organizer know why I won't be attending their meeting (or that I will be). Note: This folder is the only one that shows the total number of items in it, instead of the total unread. "Inbox" The only email that ends up here is email sent TO me and me only. Note that this is also the only email that shows up above the systray icon in the notification toast – all other emails cannot interrupt. "ToMe++" Email where I am on the TO line, but there are other recipients as well (on the TO or CC line). "CC" Email where I am on the CC line. I need to read these, but nobody is expecting a response or action from me so they are not as urgent (and if they are and follow up with me, they'll receive a link to this). "@ XYZ" Emails to aliases that are about projects that I directly work on (and I wasn't on the TO or CC line, of course). Test: these projects are in my commitments that I get measured on at the end of the year. "Z Mass" and subfolders under it per distribution list (DL) Emails to aliases that are about topics that I am interested in, but not that I formally own/contribute to. Test: if I unsubscribed from these aliases, nobody could rightfully complain. "Admin" folder, which resides under "Z Mass" folder Emails to aliases that I was added typically by an admin, e.g. broad emails to the floor/group/org/building/division/company that I am a member of. "BCC" folder, which resides under "Z Mass" Emails where I was not on the TO or the CC line explicitly and the alias it was sent to is not one I explicitly subscribed to (or I have been added to the BCC line, which I briefly touched on in another post). When there are only a few quick minutes to catch up on email, read as much as possible from these folders, in this order: Invites, Inbox, ToMe++. Only when these folders are all read (remember that doesn't mean that each email in them has been fully dealt with), we can move on to the @XYZ and then the CC folders. Only when those are read we can go on to the remaining folders. Note that the typical flow in the "Z Mass" subfolders is to scan subject lines and use the new Ctrl+Delete Outlook 2010 feature to ignore conversations. D. DO: Use Outlook Search folders in combination with categories As you process each folder, when you open a new email (i.e. click on it and read it in the preview pane) the email becomes read and stays read and you have to decide whether: It can take 2 minutes to deal with for good, right now, or It will take longer than 2 minutes, so it needs to be postponed with a clear next step, which is one of ToReply – there may be intermediate action steps, but ultimately someone else needs to receive email about this Action – no email is required, but I need to do something ReadLater – no email is required from the quick scan, but this is too long to fully read now, so it needs to be read it later WaitingFor – the email is informing of an intermediate status and 'promising' a future email update. Need to track. SomedayMaybe – interesting but not important, non-urgent, non-time-bound information. I may want to spend part of one of my weekends reading it. For all these 'next steps' use Outlook categories (right click on the email and assign category, or use shortcut key). Note that I also use category 'WaitingFor' for email that I send where I am expecting a response and need to track it. Create a new search folder for each category (I dragged the search folders into my favorites at the top left of Outlook, above my inboxes). So after the activity of reading/triaging email in the normal folders (where the email arrived) is done, the result is a bunch of emails appearing in the search folders (configure them to show the total items, not the total unread items). To actually process email (that takes more than 2 minutes to deal with) process the search folders, starting with ToReply and Action. E. DO: Get into a Routine Now you have a system in place, get into a routine of using it. Here is how I personally use mine, but this part I keep tweaking: Spend short bursts of time (between meetings, during boring but mandatory meetings and, in general, 2-4 times a day) aiming to have no unread emails (and in the process deal with some emails that take less than 2 minutes). Spend around 30 minutes at the end of each day processing most urgent items in search folders. Spend as long as it takes each Friday (or even the weekend) ensuring there is no unnecessary email baggage carried forward to the following week. F. Other resources Official Outlook help on: Create custom actions rules, Manage e-mail messages with rules, creating a search folder. Video on ignoring conversations (Ctrl+Del). Official blog post on Quick Steps and in particular the Move Conversation to folder. If you've read "Getting Things Done" it is very obvious that my approach to email management is driven by GTD. A very similar approach was described previously by ScottHa (also influenced by GTD), worth reading here. He also described how he sets up 2 outlook rules ('invites' and 'external') which I also use – worth reading that too. Comments about this post welcome at the original blog.
