  • A way to auto cycle (close) through all screen sessions

    - by JBWhitmore
    I frequently use screen when I log into the interactive nodes to a supercomputer that I have access to -- and I often run things and move on. There are about 20 separate nodes that I can log into; and if I check any one of them I'll have something like 4 detached sessions. Each of those sessions will have maybe 5 screen sessions within that. Is there a quick way to cycle through all of these and close them down if they are not running any processes? My current process is to screen -ls and then screen -r #### then type exit until I'm back to the base screen.

  • Postfix auto create Maildir

    - by Eugene
    I've been beating my head against a wall for a while now on this one. Basically, here is the rundown: Our MX record points to a frontend SMTP server, which contains aliases for actually routing the mail. No alias, no access to the backend storage server, which is what our clients connect to. I'm upgrading the backend email server. Currently, a user is created for every email user on the server, which creates the mailbox. On the new server, everything autheticates through PAM to an LDAP server (all of which is working properly). My goal is to get Postfix to create the Maildir directory for the user automatically. This works fine when I have the /home directory with 777 permissions, but for obvious reasons, this should be avoided. I would like to do this with 775 permissions on /home with a group owner of whatever user Postfix is running as, but I can't seem to figure out what user to use. With the 777 permissions, the /home/$user/Maildir directory is created on message delivery. Does anybody know how I can do this without 777 permissions? The system I am working on is a 64-bit Debian Lenny 5.07 install. Any advice would be appreciated.

  • How to disable auto-assume in Google Chrome

    - by Ieyasu Sawada
    I've noticed that whenever I sign in in Google Chrome version 21.0 it automatically assumes and it automatically knows what I want to search. I basically use the address bar to search(my default search engine is Google) I don't go type Google.com on the address bar and then search from there. So what happens is that when I type something for example "vernier" for vernier caliper I'm automatically redirected to my facebook account which has a user account name of vern.ancheta. It's really getting annoying, this happens for every search term that I used maybe even ones that I haven't used before in my entire search history in Google. It always assumes as if it knows what I'm really thinking. What's the solution for this? Is this a bug in Google Chrome or just one of its annoying features. Please enlighten me on this.

  • Auto logon to internet provider

    - by user31673
    We use wireless internet access. The wireless is secured and to get an IP address, you provide the right key. That is setup just fine. However, on top of that, the first time we access the internet, a browser page appears and we have to enter a password. then we have access to the internet for a period of time. How can the password step be automated? I also have a web-based printer that doesn't work (except via USB connection) because it can't get out to the web. I can't change the router settings. Is there anything I can do to get the printer working and automatic the access?

  • Auto backup a user folder to a usb when usb is plugged in

    - by Azztech Computers
    I'm a computer technician and help customers everyday with their computers and smartphones and have a really basic (i think) request but dont know how to go about it. Customer always come in with broken phones, water damage, needing updates, or just want me to backup their information. I currently have a program that i use when i backup their computers it backups their iOS folder C:\Users\USER\AppData\Roaming\Apple Computer\MobileSync\Backup but what i want is a quick easy way to do this in customers houses. What i require is a way when i plug in a USB drive it AUTOMATICALLY searches for the folder and starts transferring the folder to a predefined folder on the USB drive. This was I can just plug it in and begin work on their computer or phone without the risk of losing their information. I'm sure there is a .bat/.ini file i could use but wondering if someone has already done this or something similar as I would need it to search all the USER folders not just the one I'm logged into. Thanks in advance

  • Most secure way to have IPtables auto-loaded using Debian / Linux

    - by networkIT
    I'd like to know the safest way to load iptables using Debian. Of course, I can use a script that uses iptables-restore : #!/bin/sh iptables-restore < /etc/firewall.conf but : 1) where is the safest place to have it loaded ? /etc/network/if-up.d ? I'm concerned about the script being loaded early enough at boot time, and reliably enough when plugging/unplugging interfaces ... 2) is this script method using iptables-restore the most secure way ? 3) additionnally, how much does the answer validity stretch to other Linux distros ( Ubuntu, Fedora, CentOS ) ? Thanks ^^

  • What is the best way to auto failover to backup WAN link for web server

    - by user66735
    Hi Iam looking for the best way to ensure my server ( application ) remains available for all my users (on web/LAN/WAN ), when my primary ISP link fails. My server is behind a firewall on which both my primary & secondary links land. I have already assigned multiple IPs (both ISP's static IP) to the 'A' record ( host.example.com ) in the DNS. However in a round robin scenario is there a way I can ensure that my web user will not see a "cannot dislay web page" error ever ?? What are the better methods to achieve this??

  • Auto-scaling EC2 Servers and Updating Code

    - by jstats
    We've come to the point where we need to set up autoscaling for our web server and I'm unsure how to go about the process of scaling servers and updating the the existing code without remaking a new AMI and changing the autoscale config to use it. I've read a bit about people bundling the new code and uploading it to s3 and having new servers grab the bundle on boot up but that doesn't seem all that pleasant either. Currently the web app's files live in a git repo, and when we update the code, we push it to github, ssh into the web app and run a hook to bring down the latest code. So I was thinking that another option could be to just run that hook on an hourly or daily cron task. Unfortunately that doesn't cover everything type of update (for example new blog posts' images and such which aren't included in the git repo) but it's something. Could anyone provide some advice on what a common solution is or anything as to why my proposed solution is a bad idea? Thanks all

  • Excel table auto update

    - by Mike
    So I have a table in Excel with formulas. When I add a new row, the new row automatically fills in the formulas as well, which is great. My problem is that it also changes the formula in the row above the added row as well. Here's what happens specifically: My table's last row is row 24. A formula I have in that row is the following: =COUNTIF(C$11:C24,"y")/(COUNTIF(C$11:C24,"Y")+COUNTIF(C$11:C24,"N")) When I add in data in row 25 the formula is updated in row 25 as well, which is what I want, to the following: =COUNTIF(C$11:C25,"y")/(COUNTIF(C$11:C25,"Y")+COUNTIF(C$11:C25,"N")) My problem is that the row above also updates - my row 24 changes to the same as row 25 (the C24 goes to C25). Why is my row 24 formula changing when I add a row 25? Note, my formulas above row 24 stay the same when I add in row 25 - only row 24 changes when I add in 25. Is there a way to not update the row above the row being added? This problem continues when additional rows are added - If I add in a row 26, then the formula in rows 24-26 then all reference C26. Why are they all updating?

  • Deleted exchange account still being auto suggested

    - by mike G
    I set up a new hire in our domain in exchange. When he arrived yesterday I discovered his name had been mispelled. I deleted his account and created a new account with proper spelling. The problem now is his old email address is being being suggested whenever anyone types in his first name. Users email the bad address get a bounce and create more help desk tickets. Is there a way to update exchange or purge the bad account?

  • Making Thunderbird auto-add SMTP identities whenever I reply

    - by 0xC0000022L
    How can I teach Thunderbird to automatically add an SMTP identity whenever I reply to an email directed to <whatever>@<mydomain>? So if an SMTP is configured for <mydomain> but no identity exists for <whatever>@<mydomain>, how can I make Thunderbird dynamically recognize this and add it. Currently I have to manually add the identity every single time, but I would prefer it to to be added ad-hoc. As long as Thunderbird was configured to know about the SMTP serving <mydomain> this should be trivial, but I couldn't find an option. An add-on or something like a catch-all/wildcard identity would also do as long as it doesn't require manually setting up a new identity every time.

    I need to generate folders containing certain Excel field entries: Additionally, I need to append a date to the folder name based on that entry So If I have the above Excel table, I'd need the following set of folders to be generated in the same directory: Is this possible using a macro?

  • Auto-mounting a windows share on Linux AD login

    - by Jamie
    I've managed to configure my test Ubuntu 10.04 Beta 2 Server VM to accept logins (via ssh) from users who have domain accounts in active directory via Kerberos, nsswitch.conf and PAM configurations. The final thing I'd like to happen is locating their home directory on a Windows server share. Each domain account ($USER) has a windows share ala: \\winsrvr\users\$USER. Can someone push me in the direction I need to go?

  • Application for Auto-Scaling backgrounds in Windows XP

    - by jweede
    One thing that's always annoyed me about windows XP is how there's no "scale" option for the desktop background. It either has to be stretched or centered. It's a pretty simple algorithm to scale the image so that one of the dimensions (usually height) fits on the screen. Does anyone know of a good program that does this, or is there a way to enable it?

  • Vim: auto-comment in new line

    - by padde
    Vim automatically inserts a comment when I start a new line from a commented out line, because I have set formatoptions=tcroql. For example (cursor is *): // this is a comment* and after hitting <Enter> (insert mode) or o (normal mode) i am left with: // this is a comment // * This feature is very handy when writing long multi-line comments, but often I just want a single line comment. Now if I want to end the comment series I have several options: hit <Esc>S hit <BS> three times Both of these afford three keystrokes, taken together with the <Enter> this means four keystrokes for a new line, which I think is too much. Ideally, I would like to just hit <Enter> a second time to be left with: // this is a comment * It is important that the solution will also work with different indentation levels, i.e. int main(void) { // this is a comment* } hit <Enter> int main(void) { // this is a comment // * } hit <Enter> int main(void) { // this is a comment * } I think I have seen this feature in some text editor a few years ago but I do not recall which one it was. Is anyone aware of a solution that will do this for me in Vim? Pointers in the right direction on how to roll my own solution are also very welcome.

  • Auto restart server if virtual memory is too low

    - by Sukhjinder Singh
    There are quite number of software running on my server: httpd, varnish, mysql, memcache, java.. Each of them is using a part of the virtual memory and varnish was configured to be allocated 3GB of memory to run. Due to high traffic load which is 100K, our server ran out of memory and oom-killer is invoked. We've to reboot the server. We have 8GB of Virtual Memory and due to some reason we cannot extend to larger memory. My question is - Is there any automated script, which will monitor how much virtual memory left and based upon certain criteria, lets say if 500MB left than restart the server automatically? I do know this is not the proper solution but we have to do it, otherwise we don't know when server will get OOM and by the time we know and restart the server, we lost our visiting users.

  • Remote desktop auto start session on workstation login

    - by me2011
    I am setting up Remote Desktop Services for use by one of our remote offices. The workstations at the remote office are all Windows 7 Pro, joined to the domain. There is nothing installed on the local workstation othern than the Win7 OS. The remote and main office are linked via VPN. The workers will login to the local workstation, using their domain login, then right now double click an icon on the desktop which will do the RDP to the Remote Desktop Server. This does work fine, but requires some user education. Is there a way that when the user logs into the local workstation, it will start the RDP session right away and pass their username/password through as well? Would using a thin client PC do what I am asking? Thanks.

  • How to disable template auto-format in Eclipse?

    - by Matiaan
    I have a template (sleep) in Eclipse 4.2.1 that should expand to try { Thread.sleep(1000); } catch (Exception e) {} I want Eclipse to add it as one line, just as I put it in the template. However, Eclipse autoformats it after inserting to: try { Thread.sleep(1000); } catch (Exception e) { } I have tried @formatter:off, but that does not work. I have code cleanup switched off. Is there any way to disable formatting for all templates, since the only templates I use are one-liners anyway?

  • Smart Auto-completion in SVN (and other programs!)

    - by Jimmy
    When I type "svn add path/to/somefile..." and tab to autocomplete, the system should ONLY complete files/directories that are NOT under currently under SVN control. Likewise, when I commit, remove or resolve files, the tab completion should only complete files that are relevant to what I'm doing. This is especially important in SVN where I can waste thousands of keystrokes typing long path and file names, but it of applies to other programs. I know bash has a bash_completion file that can be used to programatically alter this behaviour but I've not found a decent example of SVN completion which actually completes file names rather than SVN command names. My question is: Does anyone have such a setup? Does anyone use a different shell or tool that does something similar? Has anyone given this any thought?

  • Generate POCO classes in different project to the project with Entity Framework model

    - by Max
    I'm trying to use the Repository Pattern with EF4 using VS2010. To this end I am using POCO code generation by right clicking on the entity model designer and clicking Add code generation item. I then select the POCO template and get my classes. What I would like to be able to do is have my solution structured into separate projects for Entity (POCO) classes and another project for the entity model and repository code. This means that my MVC project could use the POCO classes for strongly typed views etc and not have to know about the repository or have to have a reference to it. To plug it all together I will have another separate project with interfaces and use IoC. Sounds good in my head I just don't know how to generate the classes into their own project! I can copy them and then change the namespaces on them but I wanted to avoid manual work whenever I change the schema in the db and want to update my model. Thanks

  • Good tools which generate NUnit unit tests for .NET assemblies in Visual Studio 2008

    - by andy
    Hey guys, I'm pretty new to Unit Testing so bare with me. I realize that best best practice is not to auto generate unit tests, however I'd like to use Code Generation to set-up the basic skeleton of the tests. Now, I know Visual Studio 2008 already has the built in "create tests", however, it just creates a flat list of all the classes it's going to test... and it's not for NUnit right? Ideally, I'd like the code generation to follow the folder AND namespace structure of the assembly its generating tests for. Can you guys recommend any good tools which generate NUnit unit tests for .NET assemblies in Visual Studio 2008? cheers!
