• Setting the default permissions for files uploaded via FTP to a directory

  - by Kerri

  Disclaimer: I'm just a web designer/coder, and server admin stuff is my weakest point of them all. So be easy on me (and very specific). I'm using a simple CMS (Unify) on a site, where part of the functionality is that the client can upload files to a specified directory (using FTP). The permissions for the upload directory are set to 755. But when files are uploaded through the interface, they are uploaded with permissions set to 640 (instead of 644), so site visitors cannot acces the files. When I emailed the CMS's support about this, they told me that it was a server setting, and I need to make sure that files uploaded through FTP are set to 644. Makes perfect sense, but I have no idea how to do this. Any help would be greatly appreciated. This site is a shared site hosted by Network Solutions (Unix), so my access options are limited. I can edit .htaccess files, and php.ini, but that's about all I have access to. It appears I can't even log on via shell. ETA: 11/11/2010 Thanks all. I was able to work around this problem by setting up the CMS's settings in a different way. I'd be interested in following up on Nick O'Niel's suggestions, because I think he's on the right track, but unfortunately I can't access the necessary files on this particular server. So, anyway, I'm leaving this open, since the original questions isn't exactly resolved. Unfortunately, I probably can't put a correct answer to the test, since the shared server in question has nearly all of its config files tightly locked down.

• Where is the bare cygwin package list located and how do I manipulate it?

  - by matnagel

  Where is the bare cygwin package list located and how do I manipulate it programmatically or from a shell or with a different method than the gui? I know the gui (setup.exe), and I'd love to go one or more levels deeper. I can retrieve a list of selected/installed packages ( http://serverfault.com/questions/83456/cygwin-package-management ), but how do I write it back or to a different machine? What I have in mind is when I install a new windows I would like to start with my package list in text form, an apply or inject it somehow to the new system. Where is it? In the registry? In a binary file? in a local database? Or has anybody done this, is there a tool, a tutorial? The essence of what I want is to manipulate the selected package list with something else than the gui. It is ok for me to use the gui for the setup process. So I could imagein manipulating the package List and then run setup.exe and just click through it. Note: I do not want to manipulate the list of already installed packages but of packages that "should be installed". But if htis is not possible, maybe there is some workaround. E.g add an outdated version as installed and the installer will then install the new version.

• First web server questions

  - by Graeme

  Hi there, Just looking for some help/suggestions with this. I require my own server for an upcoming project that will be hosting users websites. I want to build a control panel the user can log into and modify their website which will be stored elsewhere on the server. This all seems easy enough, It's just managing domains and emails that confuse me. What should I look for to manage domain names and point them to the correct website and also what would be the best way to manage email accounts/set up new ones etc. I want to avoid cPanel/WHM if possible, I'm looking to control most things through the control panel I will be building. So any suggestions on this would be useful as well, as I will be wanting to add email accounts through php (Can be done using a shell I assume?). I will also be wanting to measure bandwidth used on the websites contained in each users directory, any suggestions on making this possible? I'm really looking for some suggestions on what software to use to set this up, any advice would be really helpful! Thanks, Graeme

• Change Windows 7 Explorer's Details Pane limits

  - by Paul

  For some reason, MS decided to completely kill the status bar's functionality in Win7 (and maybe Vista, but I don't know for sure). I have tried all possible options such as Classic Shell and so on. Basically, the one thing I miss most is seeing at a glance the total size of my selected files. I know I can press Alt+Enter or whatever, but that's not the point. The point is that the so-called 'details' pane stops providing details if more than 15 files are selected! WTH? Cannot understand the reason behind such a stupid arbitrary limit, that doesn't seem to be user-configurable at all. Anyway, what I'm looking for is a way to change that limit, either via the registry or otherwise. If changing the limit isn't possible, would it be possible for some programming genius to create a very small optimized light-weight non resource-hungry (you get the idea!) program whose sole purpose will be to automatically click the "Show more details..." link in the details pane after every file selection? For bonus points, the program should wait for a second or two after file selection is complete to do this, so that selecting multiple files in quick succession doesn't hit the HDD repeatedly. Any takers for the challenge? :)

• samba joined to AD canot see users when in the security tab on client

  I've got samba joined via kerberos and winbindd to our AD network and user authentication and everything else is working great.

• Notebook Operating System with extreme support cycles/security updates

  - by leto

  Hello there, after reading the announcements about Mac OS X "Lion" and Apples political decision, I've had enough. I'm a longtime Apple User since 1992, have always felt at home there, but am trying to switch to alternative Operating System since a year. I've also been working with Unix machines since 2001, so I'm looking in one of the free Unices or a Linux. Since I last looked at the desktop in 2002 choke much has changed, it seems. So I'm lost once more in the war between desktop environments and software. To be honest: I don't care what it's name is, I want to get my job done. Here's what I set me as landmark for an operating system/software to be considered: Has to be atleast four years old Has to supply security updates for current release for atleast a year Production quality stability for the whole desktop environment (!) No f****g commercial stuff that tends to supply me with privacy invading App Store or Cloud space So far I'm running a MacBook from 2007, 4 Gig memory, 250 Gig disk and I need: IMAPs for Mail since 1995 Webbrowser sic Shell Keeping current with Updates/Upgrades with no more than 5 Minutes spent in entering commands (makes it hard for OpenBSD ;-) ) A desktop filemanger would be nice, but is a bonus. What can you suggest as operating system? The one with the longest support cycles and best chance to survive the next 10 years will win a new user, even sending patches when needed :-) Greets

• chrooted sftp user with write permissions to /var/www

  - by matthew

  I am getting confused about this setup that I am trying to deploy. I hope someone of you folks can lend me a hand: much much appreciated. Background info Server is Debian 6.0, ext3, with Apache2/SSL and Nginx at the front as reverse proxy. I need to provide sftp access to the Apache root directory (/var/www), making sure that the sftp user is chrooted to that path with RWX permissions. All this without modifying any default permission in /var/www. drwxr-xr-x 9 root root 4096 Nov 4 22:46 www Inside /var/www -rw-r----- 1 www-data www-data 177 Mar 11 2012 file1 drwxr-x--- 6 www-data www-data 4096 Sep 10 2012 dir1 drwxr-xr-x 7 www-data www-data 4096 Sep 28 2012 dir2 -rw------- 1 root root 19 Apr 6 2012 file2 -rw------- 1 root root 3548528 Sep 28 2012 file3 drwxr-x--- 6 www-data www-data 4096 Aug 22 00:11 dir3 drwxr-x--- 5 www-data www-data 4096 Jul 15 2012 dir4 drwxr-x--- 2 www-data www-data 536576 Nov 24 2012 dir5 drwxr-x--- 2 www-data www-data 4096 Nov 5 00:00 dir6 drwxr-x--- 2 www-data www-data 4096 Nov 4 13:24 dir7 What I have tried created a new group secureftp created a new sftp user, joined to secureftp and www-data groups also with nologin shell. Homedir is / edited sshd_config with Subsystem sftp internal-sftp AllowTcpForwarding no Match Group <secureftp> ChrootDirectory /var/www ForceCommand internal-sftp I can login with the sftp user, list files but no write action is allowed. Sftp user is in the www-data group but permissions in /var/www are read/read+x for the group bit so... It doesn't work. I've also tried with ACL, but as I apply ACL RWX permissions for the sftp user to /var/www (dirs and files recursively), it will change the unix permissions as well which is what I don't want. What can I do here? I was thinking I could enable the user www-data to login as sftp, so that it'll be able to modify files/dirs that www-data owns in /var/www. But for some reason I think this would be a stupid move securitywise.

• Correct MySQL username/password, but getting Access Denied error when run from script

  - by Nick

  I'm currently trying to run the following command from within a shell script. /usr/bin/mysql -u username -ppassword -h localhost database It works perfectly fine when executed manually, and not from within a script. When I try to execute a script that contains that command, I get the following error: ERROR 1045 (28000) at line 3: Access denied for user 'username'@'localhost' (using password: YES) I literally copied and pasted the working command into the script. Why the error? As a sidenote: the ultimate intent is to run the script with cron. EDIT: Here is a stripped down version of my script that I'm trying to run. You can ignore most of it up until the point where it connects to MySQL around line 19. #!/bin/sh #Run download script to download product data cd /home/dir/Scripts/Linux /bin/sh script1.sh #Run import script to import product data to MySQL cd /home/dir/Mysql /bin/sh script2.sh #Download inventory stats spreadsheet and rename it cd /home/dir /usr/bin/wget http://www.url.com/file1.txt mv file1.txt sheet1.csv #Remove existing export spreadsheet rm /tmp/sheet2.csv #Run MySQL queries in "here document" format /usr/bin/mysql -u username -ppassword -h localhost database << EOF --Drop old inventory stats table truncate table table_name1; --Load new inventory stats into table Load data local infile '/home/dir/sheet1.csv' into table table_name1 fields terminated by ',' optionally enclosed by '"' lines terminated by '\r\n'; --MySQL queries to combine product data and inventory stats here --Export combined data in spreadsheet format group by p.value into outfile '/tmp/sheet2.csv' fields terminated by ',' optionally enclosed by '"' lines terminated by '\r\n'; EOF EDIT 2: After some more testing, the issue is with the << EOF that is at the end of the command. This is there for the "here document". When removed, the command works fine. The problem is that I need << EOF there so that the MySQL queries will run.

• How do I identify Blackberry / OWA users in my IIS logs?

  - by Quinten

  We just rolled out a Blackberry Express Server, and would like to make sure that all Blackberry devices that our users own are connecting SOLELY through the BES server. We are running Exchange 2010 SP1. I've read some links that discuss blocking BIS at the firewall level. Before doing that, however, I'd like to individually contact all users with Blackberries and make sure that they have a chance to switch to the BES server. I've sent a company-wide email, but unsurprisingly folks tend to tune these out until they are forced into action. Is there an easy way to identify the users with Blackberries by searching IIS logs, or perhaps using the Exchange Management Shell? Especially some automated way? I've tried searching for the Blackberry identifier, but it does not appear next to any user name, so it's not as helpful as it could be. Edit: to clarify, what I'm talking about is the fact that Blackberries can use OWA to download mail to the phone. We do not allow IMAP or POP access through our firewall so that's not a concern--just folks with Blackberries using Blackberry's hack to allow it to connect to Exchange without a BES server. As far as I know, Blackberries are the only popular phones that use this method to download mail.

• How do I find my missing songs from last.fm?

  - by duality_

  My disk failed with all my music with it, lots of them. But luckily, I scrobbled every song to last.fm. I am looking for a way to scan my disk for my songs and check last.fm and tell me which songs are missing from my disk that are present on last.fm. So to recap: I would need to log into my last.fm account and compile a list of all the songs I have scrobbled and then scan my computer for missing songs. Is there a program or script that does this? I don't mind it being a shell script even. Edit: I know this is possible because I came close to this a little time ago. I created a PHP script (web page) that got all my songs through Last.fm API and then went through my files on disk and read their id3 tag. I got very close: the program showed missing songs, but there were many small issues (id3 reading was buggy, tags had different data, etc.) that required more programming time that I didn't have.

• Windows 7: Moving Program Files location during install using unattend.xml

  - by Shevek

  I am planning on using an unattend.xml to create a Windows 7 Ultimate 64-bit setup with Users and ProgramData on a 2nd drive. I have found many samples of how to do this (see below). However I would also like to move Program Files to a 3rd drive as well. i.e.: C:\Windows [SSD] D:\Users [HDD1] D:\ProgramData [HDD1] P:\Program Files [HDD2] P:\Program Files (x86) [HDD2] I have found that this was possible using unattend.txt in XP but all documentation or examples I find about Win 7 only mention Users and ProgramData, not Program Files. Is this possible using an answer file? Sample unattend.xml for Users and ProgramData: <?xml version="1.0" encoding="utf-8"?> <unattend xmlns="urn:schemas-microsoft-com:unattend"> <settings pass="oobeSystem"> <component name="Microsoft-Windows-Shell-Setup" publicKeyToken="31bf3856ad364e35" language="neutral" versionScope="nonSxS" processorArchitecture="amd64"> <FolderLocations> <ProfilesDirectory>D:\Users</ProfilesDirectory> <ProgramData>D:\ProgramData</ProgramData> </FolderLocations> </component> </settings> </unattend>

• How to correctly set GNU Screen to display currently running program in hardstatus

  - by johnny_bgoode

  I posted this question on SuperUser but it's hardly getting any views, so I thought I'd ask here as well. In bash, to display the name of the current program in the GNU Screen hardstatus line takes only two configuration lines. First, tell screen what the end of your prompt normally looks like, and supply a default title for a window when you are sitting at in the shell: shelltitle "$ |bash" Next, place this escape sequence in the PS1 variable, before the characters that normally terminate the prompt '$ ' in this case: \033k\033\\\ This technique works, to a point. The hardstatus window title is updated to the name of the currently running program, and then switches back to the default title shortly after execution is finished. One major problem, however, is that this escape string is not escaped itself, causing line-wrapping problems with commands longer than the initial line. This was annoying, so I set out looking for a solution. Turns out, simply escaping the previous escape sequence corrects line wrapping: [\033k]\[\033\\\] Great! My hardstatus window title still updates to the name of the currently running program, and now my longer commands wrap to the second line correctly. However, with this new escape sequence in my PS1, screen updates the window title to the actual command I am typing, not simply the name of the current program once it is executed. I am wondering, has anyone gotten this working correctly - i.e. line wrapping and proper updating of the hardstatus window title? Thanks!

• Does the OSS Backup Solution amanda.org support sparse files?

  - by user97961

  I want to (or better have to) do Backups of my KVM Virtual Machine images. I have searched for days for a good Backup Soloution. I know amanda is a very good solution. It would be kinf if someone kenn tell me if the following is supported: Trigger the Creation of LVM Snapshot (by invoking a Shell Script that I will write for that purpose) Do a Differential/Delta Backup on my KVM LVM qcow2 sparse file. = I only want to copy the actually changed bits/bytes (=Delta Backup). And it has to support that the file to be backuped up is a sparse file. (Rsync seems to have some kind of problems in regard to this (if the file does not exist yet on the other side... Then it will create a full file, not a sparse file)) Release the LVM Snapshot (By invoking a Script that I will write for that purpose) It's strange, I have nowhere found any documentation about this fact when searching the internet. Zmanda (Commercial Edition) has support vom XEN VM Backup (but not for KVM as far as I can tell)...

• Zsh super slow inside my Git repo

  - by Jason Swett

  My Zsh is super slow inside a certain Git repo of mine. When I Google "zsh git slow", I get a bunch of results about Git autocompletion being slow, but autocompletion isn't necessarily my problem; it's everything. I tried removing all plugins and that, strangely, didn't do anything at all when I opened a new shell. Zsh would still do Git stuff inside my Git repo. I found this snippet on this page: function git_prompt_info() { ref=$(git symbolic-ref HEAD 2> /dev/null) || return echo "$ZSH_THEME_GIT_PROMPT_PREFIX${ref#refs/heads/}$ZSH_THEME_GIT_PROMPT_SUFFIX" } That made everything fast again, but it also gave me a prompt that looks like this: ? snip git:(master Note the missing right parenthesis. That's kind of lame. Plus the whole thing just seems like a hack I shouldn't have to do. There's also this promising-looking SU question, but the links on the accepted answer are dead. How can I get my Zsh not to be slow inside a Git repo?

• Why do hosts prefer Linux to Windows Server?

  - by iconiK

  So far I see a HUGE majority of hosts provide only Linux shared hosting, providing Windows only to VPS (or even to only dedicated servers). Why is it so? While Windows is a lot more expensive than Linux (though it depends on a lot of factors, not just initial and support license cost), it also provides ASP.NET, IIS and of course, Microsoft SQL Server. I know in the past it might have been because of cPanel being Linux only but now they have a Windows version. But still, why is Linux predominantly used on shared hosting? PHP works on both systems. IIS can be (and probably is) faster. MySQL runs on both systems as well. cPanel has a Windows version. Python, Perl, Ruby, all run on Windows as well. You even have MS SQL Server Express, which I find more superior than MySQL in both speed and features. Access is there for low usage requirements, as is SQLite (which is so great for quick small stuff). And with PowerShell you have a good alternative to the Unix shell. EDIT: I am looking for common reasons, I realize each hosting company (and/or it's clients) may have different needs. This becomes very important when you get to VPS or Cloud which give you a full operating system to use.

• Using the same Windows 8 Upgrade installer on multiple PCs

  - by Karan

  As per this article: You may transfer the software to another computer that belongs to you. … You may not transfer the software to share licenses between computers. But what if I have a bunch of PCs with a mix of XP/Vista/Windows 7? Can I purchase either the Windows 8 Pro Upgrade $40 (download only) or $70 (DVD) version (both of which come without a key) only once and use it to upgrade all the PCs? Since I'm not sharing the license and each PC has its own valid genuine license, it should be allowed, right, or is it illegal? Even if they want people to shell out $40/$70 for each PC, how would they enforce the use of the installer/media on only one PC each? EDIT: I have been given to believe by a source that the installer will only check for the previous OS' key, which is what is confusing me (I have never purchased an upgrade version before this, only full retail or pre-installed versions). Is this true or will I need to enter two keys to make the upgrade work, one for the previous version and then one for Windows 8? If the latter is the case, then the issue is solved since obviously the same Windows 8 key will not be valid for multiple PCs.

• How to display escaped characters in tmux status bar

  - by walrus

  i am running tmux from a tty on an embedded linux device. (NOT a terminal emulator) because the screen is rather small, i want to add some "icons" to the tmux status bar. to achieve this, i have simply created a font with the appropriate glyphs for things like battery, or wifi. i can load the font, and display the characters with calls that use an escape to the line drawing characters like so: echo -e "\xe\234\xf" \xe escapes me into line drawing character mode, \234 is my created character, and \xf returns me to normal character mode so my terminal doesnt start getting goofy. this works perfectly if i enter the command at the terminal whether tmux is started or not. the issue arises if i then try to use it in my ~/.tmux.conf file for the status bar. i currently have a line like this: set -g status-right "#(echo -e "\xe\234\xf") #(/script/to/output/powerlevel) this simply outputs \xe\234\xf powerlevel this goes the same if i try printf over echo. this is the output i would expect to get on the terminal if i made the call without passing -e to echo, or without enclosing the statement with quotes. i then decided to wrap the calls to the echo or printf in a shell script. again, the script works when called from the terminal, but not in tmux's status bar. now i get the unprintable character "?" instead of my icon, like this: ? powerlevel this is what i would expect if i did not use the line drawing escapes previously mentioned above, or if i tried to copy and paste the character as text using tmux. in addition, the calling of these character scripts screws up the rest of my status-right, as the clock has about 6 digits for minutes when it is called (though it correctly only updates two of them). how can i make tmux respect the escape characters? any help or insight is greatly appreciated.

• Spring-mvc project can't select from a particular mysql table

  - by Dan Ray

  I'm building a Spring-mvc project (using JPA and Hibernate for DB access) that is running just great locally, on my dev box, with a local MySQL database. Now I'm trying to put a snapshot up on a staging server for my client to play with, and I'm having trouble. Tomcat (after some wrestling) deploys my war file without complaint, and I can get some response from the application over the browser. When I hit my main page, which is behind Spring Security authentication, it redirects me to the login page, which works perfectly. I have Security configured to query the database for user details, and that works fine. In fact, a change to a password in the database is reflected in the behavior of the login form, so I'm confident it IS reaching the database and querying the user table. Once authenticated, we go to the first "real" page of the app, and I get a "data access failure" error. The server's console log gets this line (redacted): ERROR org.hibernate.util.JDBCExceptionReporter - SELECT command denied to user 'myDbUser'@'localhost' for table 'asset' However, if I go to MySQL from the shell using exactly the same creds, I have no problem at all selecting from the asset table: [development@tomcat01stg]$ mysql -u myDbUser -pmyDbPwd dbName ... mysql> \s -------------- mysql Ver 14.12 Distrib 5.0.77, for redhat-linux-gnu (i686) using readline 5.1 Connection id: 199 Current database: dbName Current user: myDbUser@localhost ...

Nothing is changing the behavior of this thing. What gives?

• Interesting phenomenom with Windows Server 2008 R2 user access controls and NTFS ACLs

  - by Simon Catlin

  One to try, and I'd appreciate any thoughts on this. On a Windows Server 2008 R2 box (or presumably 2008 R1, Windows Vista or Windows 7): i) Logon as an administrator, and create a new NTFS volume ii) Blow away the standard MS ACLS on the root of the volume (which are laughable), and replace with Administrators:Full Control, System:Full Control, e.g.: echo Y|cacls.exe d:\ /g "Administrators:F" "SYSTEM:F" iii) Now, from a Command Prompt shell window or PowerShell window, switch to that drive (cd /d D:\ or set-location D:\ ). Works fine... no issues. iv) Now, try to browse to the root of the new volume using MS Explorer... Access denied. Now, I've kind of convinced myself that it is UAC getting in the way, as you can add "Authenticated Users:List" access to D:\ and Explorer then works. I can only assume that MS Explorer isn't able to use the "admin" token for the Administrator. Browsing to explorer.exe and doing a "Run as administrator" has no effect. Any thoughts? Cheers in advance.

• configuring lighttpd for large downloads

  - by ahmedre

  i run a web site that hosts pages that are just general scripts (php, etc) and mp3 downloads (some of which are fairly large - up to 200mb). i am running lighttpd on the servers on linux (ubuntu 64). everything is fine, but under high load, the server is not accessible (or very slow - even sshing in takes a while), and i am guessing this is due to a huge number of mp3 downloads at that time. consequently, dns sees the server as down and redirects all the traffic to the other servers, and after a while, it comes back up and things work again. so what's the best way to fix this? ideally, i want the server to continue running (and the web pages - php etc - to always work, but downloads don't always have to work). should i just have 2 web servers running (one for the downloads and one for the php pages), or is it perhaps something i can fix in my lighttpd configuration? here are the snippets from my configuration: server.max-worker = 4 server.max-fds = 2048 server.max-keep-alive-requests = 4 server.max-keep-alive-idle = 4 server.stat-cache-engine = "fam" fastcgi.server = ( ".php" => (( "bin-path" => "/usr/bin/php-cgi", "socket" => "/tmp/php.socket", "max-procs" => 1, "idle-timeout" => 20, "bin-environment" => ( "PHP_FCGI_CHILDREN" => "64", "PHP_FCGI_MAX_REQUESTS" => "1000" ), "bin-copy-environment" => ( "PATH", "SHELL", "USER" ), "broken-scriptfilename" => "enable" )) ) # normal php site $HTTP["host"] =~ "bar.com" { server.document-root = "/usr/local/www/sites/bar.com/" accesslog.filename = "|/usr/sbin/cronolog /var/log/lighttpd/%m/%d/%H/bar.log" } # download site $HTTP["host"] =~ "(download|stream).foo.com" { server.document-root = "/home/audio/" dir-listing.activate = "enable" dir-listing.hide-dotfiles = "enable" evasive.max-conns-per-ip = 1 evasive.silent = "enable" # connection.kbytes-per-second = 256 accesslog.filename = "|/usr/sbin/cronolog /var/log/lighttpd/%m/%d/%H/download.log" }

• Determine if the "yes" is necessary when doing an SCP

  - by glowcoder

  I'm writing a Groovy script to do an SCP. Note that I haven't ran it yet, because the rest of it isn't finished. Now, if you're doing an scp for the first time, have to authenticate the fingerprint. Future times, you don't. My current solution is, because I get 3 tries for the password, and I really only need 1 (it's not like the script will mistype the password... if it's wrong, it's wrong!) is to pipe in "yes" as the first password attempt. This way, it will accept the fingerprint if necessary, and use the correct password as the first attempt. If it didn't need it, it puts yes as the first attempt and the correct as the second. However, I feel this is not a very robust solution, and I know if I were a customer I would not like seeing "incorrect password" in my output. Especially if it fails for another reason, it would be an incredibly annoying misnomer. What follows is the appropriate section of the script in question. I am open to any tactics that involve using scp (or accomplishing the file transfer) in a different way. I just want to get the job done. I'm even open to shell scripting, although I'm not the best at it. def command = [] command.add('scp') command.add(srcusername + '@' + srcrepo + ':' + srcpath) command.add(tarusername + '@' + tarrepo + ':' + tarpath) def process = command.execute() process.consumeOutput(out) process << "yes" << LS << tarpassword << LS process << "yes" << LS << srcpassword << LS process.waitfor() Thanks so much, glowcoder

• How to encourage Windows administrators to pick up scripting?

  - by icelava

  When I worked as an administrator in my first job, I was frustrated that our administration processes with Windows servers were a series of point-and-clicks; we could never match the level of efficiency with the Unix servers which had a group of shell scripts to automate a lot of the work. I soon read about WSH and ADSI and wasted no time learning just how much automation I was able to achieve with scripting. There was a huge problem though - almost none of my Windows colleagues were really interested in learning scripting. They seemed happy with the manually mouse-clicking chores and were never excited at the prospect of using scripts to do the work on their behalf. I struggled to convince them to pick up scripting skills despite the evident increases in efficiency. I left that job in pursuit of a full-time software development career thereafter. Almost a decade on working in various environments and different customers, I still encounter Windows administrators mainly possessing this general "mood" where they would avoid scripting as much as possible. Despite the increasing level of accessibility Windows server technologies are opening up for scripting and automation. I am almost certain the majority of administrators are administrators precisely because they absolutely hate performing any kind of programming duties. What are some means to encourage and motivate administrators that scripting can really help them in the long run?

• SSH Interactive mode not working

  - by Ekin Koc

  I have a Debian based linux server running for a year or so, without any problems. A couple of days ago, ssh interactive mode stopped working for no reason. I mean, I can open an ssh connection just fine, the server greets me with shell but I just can't type anything. However, if I send commands like this: ssh [email protected] cat /var/log/messages, I get the response. I dug through several logs and found one message, which feels remotely relevant to the problem; sh kernel: [10222733.062511] ------------[ cut here ]------------ sh kernel: [10222733.062522] WARNING: at /build/buildd-linux-2.6_2.6.32-39-amd64-7yVIH2/linux-2.6-2.6.32/debian/build/source_amd64_none/drivers/char/tty_ldisc.c:738 tty_ldisc_reinit+0x46/0x7b() sh kernel: [10222733.062526] Hardware name: PowerEdge R210 II sh kernel: [10222733.062528] Modules linked in: ipt_MASQUERADE iptable_nat nf_nat nf_conntrack_ipv4 nf_conntrack nf_defrag_ipv4 ip_tables x_tables sha1_generic arc4 ecb ppp_mppe ppp_async crc_ccitt ppp_generic slhc loop snd_pcm snd_timer snd soundcore snd_page_alloc i2c_i801 i2c_core pcspkr evdev joydev dcdbas container button processor ext3 jbd mbcache sg sd_mod sr_mod crc_t10dif cdrom usb_storage usbhid hid mpt2sas ahci ehci_hcd libata scsi_transport_sas usbcore bnx2 nls_base scsi_mod fan thermal thermal_sys [last unloaded: scsi_wait_scan] sh kernel: [10222733.062568] Pid: 8662, comm: sshd Not tainted 2.6.32-5-amd64 #1 sh kernel: [10222733.062569] Call Trace: sh kernel: [10222733.062572] [<ffffffff811ff056>] ? tty_ldisc_reinit+0x46/0x7b sh kernel: [10222733.062574] [<ffffffff811ff056>] ? tty_ldisc_reinit+0x46/0x7b Is there any way to get back the sshd working in interactive mode? I tried restarting sshd but that is no help. And somehow, I can not reboot the server. Tried sending shutdown -r now and reboot but it refuses to go down. Should I go ahead and request a physical reboot?

• How do I enable additional debugging output from Ansible and Vagrant?

  - by Brian Lyttle

  I'm investigating Ansible for server and application provisioning. My application is currently provisioned with shell scripts in Vagrant. Rather than rewrite my scripts I've taken a sample and attempted to deploy it. It appears to deploy fine, but I've seeing a failure message after what looks like a series of successful steps: » vagrant provision ~/vm/blvagrant 1 ? [default] Running provisioner: ansible...
