• Stream tar.gz file from FTP server

  - by linker

  Here is the situation: I have a tar.gz file on a FTP server which can contain an arbitrary number of files. Now what I'm trying to accomplish is have this file streamed and uploaded to HDFS through a Hadoop job. The fact that it's Hadoop is not important, in the end what I need to do is write some shell script that would take this file form ftp with wget and write the output to a stream. The reason why I really need to use streams is that there will be a large number of these files, and each file will be huge. It's fairly easy to do if I have a gzipped file and I'm doing something like this: wget -O - "ftp://${user}:${pass}@${host}/$file" | zcat But I'm not even sure if this is possible for a tar.gz file, especially since there are mutliple files in the archive. I'm a bit confused on what direction to take for this, any help would be greatly appreciated.

• Same script, different behavior [migrated]

  - by Antoine_935

  I just stumbled upon an interesting bug... Still trying to figure out what is exactly happening. Maybe you can help. First, the context. I'm currently building yet another man to html converter (for some reasons I won't motivate here, but I need it). So, have a look at the screenshot below (see the link), more precisely at the outlined spots. See? On the upper shell, I have &lt ; and &gt ;, that is, escaped html. While on the shell below I have < and directly. But as you can see (or do I seriously need looking glass ?), the command man 2 semget | webmanneris the same on both sides, as is the which webmanner. The two are executed roughly at the same moment, with no modification made to the script between. [Oops, cannot post pictures just yet... Here comes the link] http://aspyct.org/media/webmanner-bug.png But the shell below is older (open about 1 hour ago). Newer shells all print out &lt ;. So my first guess was that it somehow had a cached reference to the old inode of the file, or old blocks or whatever. So I modified parts of the script, at the start and then at the end, to print different messages. And, surprise, the message shown up on both terminals. But still, same difference between &lt ; and <. I'm confused... How to explain that behavior? I'm working on a OSX 10.8 (Mountain Lion) EDIT: OK, there is one big difference: the shell below uses ruby 1.9.3, while above is 1.8.7. Is there any known difference in string handling between the two versions ?

• Automate setup of constrained kerberos delegation in AD

  - by Grhm

  I have a web app that uses some backend servers (UNC, HTTP and SQL). To get this working I need to configure ServicePrincipalNames for the account running the IIS AppPool and then allow kerberos delegation to the backend services. I know how to configure this through the "Delegation" tab of the AD Users and Computers tool. However, the application is going to be deployed to a number of Active Directory environments. Configuring delegation manually has proved to be error prone and debugging the issues misconfiguration causes is time consuming. I'd like to create an installation script or program that can do this for me. Does anyone know how to script or programmatically set constrained delegation within AD? Failing that how can I script reading the allowed services for a user to validate that it has been setup correctly?

• Verify linux user passwords

  - by zero_r

  Hi there I got a linux server that has several dozen users. I also have the cleartext password for every user (i know - bad security). I would like to know if the passwords are correct. Since the users are all ftp users and have the nologin shell, I cannot just write a script to check if login works. How can I do a local check on passwords? Script output could look like this: $ check_userpw < user_pw_list.txt user1 ok user2 ok user3 mismatch! user4 ok Thanks

• How Do I Parse a String?

  - by Russ

  I am new to bash, and I am creating a script that loops through the files in a directory and based on part of the filename, does something with the file, so far I have this: #!/bin/bash DIR="/Users/me/Documents/import/*" for f in "$DIR" do $t=?????? echo "Loading $f int $t..." done so $f will output something like this: /Users/me/Documents/import/time_dim-1272037430173 out of this, I want time_dim, the directory can be variable length and -1272037430173 is a fixed length (it's the unix timestamp btw). What is the best way to go about this?

• Physical button to run scripts on a windows machine?

  - by NoCarrier

  I frequently come in contact with people who absolutely cannot operate a PC, no matter how you train them. I need some sort of programmable physical button or remote control, where when they click it, it will execute a script on a windows machine. (and no, wiseguys, a mouse won't do) Does such a thing exist?

• Hyper-V: determine the guest's name given the GUID

  - by syneticon-dj

  How would I go about determining the guest's name given its GUID or vice-versa, preferably with only the Hyper-V/Server Core stock install at hands? Rationale: I am in favor of having a repository of dirty tricks to revert to when in great need. To immediately quiesce all (storage) operations of a VM guest without losing the state, I used to run kill 17 <all VM's virtual processes> (signaling SIGSTOP) and resumed afterwards using kill 19 <all VM's virtual processes> (signaling SIGCONT) in ESXi/vSphere shell. I tried the same technique with Hyper-V using Process Explorer's "Suspend" functionality on the vmwp.exe processes and it seemed to work. I have yet to find a way for easily identifying the processes to suspend, though - the vmwp command line is only listing a GUID.

• How can I check for a string match AND an empty file in the same if/then bash script statement?

  - by Mike B

  I'm writing a simple bash script to do the following: 1) Check two files (foo1 and foo2). 2) If foo1 is different from foo2 and foo1 NOT blank, send an email. 3) If foo1 is the same as foo2... or foo1 is blank... do nothing. The blank condition is what's confusing me. Here's what I've got to start with: diff --brief <(sort ./foo1) <(sort ./foo2) >/dev/null comp_value=$? if [ $comp_value -ne 0 ] then mail -s "Alert" [email protected] <./alertfoo fi Obviously this doesn't check for blank contents. Any thoughts on how to do that?

• Kill child process when the parent exits

  - by kolypto

  I'm preparing a script for Docker, which allows only one top-level process, which should receive the signals so we can stop it. Therefore, I'm having a script like this: one application writes to syslog (bash script in this sample), and the other one just prints it. #! /usr/bin/env bash set -eu tail -f /var/log/syslog & exec bash -c 'while true ; do logger aaaaaaaaaaaaaaaaaaa ; sleep 1 ; done' Almost solved: when the top-level process bash gets SIGTERM -- it exists, but tail -f continues to run. How do I instruct tail -f to exit when the parent process exits? E.g. it should also get the signal. Note: Can't use bash traps since exec on the last line replaces the process completely.

• Locate devices within a building

  - by ams0

  The situation: Our company is spread between two floors in a building. Every employee has a laptop (macbook Air or MacbookPro) and an iPhone. We have static DHCP mappings and DNS resolution so every mobile gets a name like employeeiphone.example.com, every macbook air gets a employeelaptop.example.com and every macbook pro gets a employeelaptop.example.com on the Ethernet interface (the wifi gets a dynamic IP from a small range dedicated for the purpose). We know each and every MAC address of phones and laptops, since we do DHCP static mapping (ISC DHCP server runs on linux). At each floor we have a Netgear stack of two switches, connected via 10GB fiber to each other. No VLANs so far. At every floor there are 4 Airport Extreme making a single SSID network with WPA2 authentication. The request: Our CTO wants to know who is present at which floor. My solution (so far): Every switch contains an table listing MAC address and originating port. On each switch stack, all the MAC addresses coming from the other floor are listed as coming on port 48 (the fiber link). So I came up with: 1) Get the table from each switch via SNMP 2) Filter out the ones associated with port 48 3) Grep dhcpd.conf, removing all entries not *laptop and not *iphone 4) Match the two lists for each switch, output in JSON or XML 5) present the results on a dashboard for all to see I wrote it in bash with a lot of awk and sed, it kinda works but I always have for some reason stale entries in the switch lookup tables, making it unreliable; some people may have put their laptop to sleep, their iphones drop connections after a while, if not woken up and so on..I searched left and right, we are prepared to spend a little on the project too (RFIDs?), does anybody do something similar? I can provide with the script if needed (although it's really specific to our switches and naming scheme). Thanks! p.s. perhaps is this a question for stackoverflow? please move if it so.

• Programmatically reconnect to wifi network

  - by ya23

  Sometimes I work with frequently-dropping wifi connections. I can either reconnect manually or wait some time (varies from few seconds to few minutes) before windows attempts to reconnect. Is there a simple way to trigger reconnect immediately after the connection was dropped? Bonus question: In this particular case I'd blame hardware, but how can I diagnose the reason of dropping connection in general?

• FTP script needs blank line

  - by Ones and Zeroes

  I am trying to determine the reason for some FTP servers requiring a blank line in the script as follows: open server.com username ftp_commands bye Refer to blank line required after username credentials. Example from: FTP from batch file another reference to the same: http://newsgroups.derkeiler.com/Archive/Comp/comp.sys.ibm.as400.misc/2008-05/msg00227.html Also discussed here: archive.midrange.com/midrange-l/200601/msg00048.html "The behavior I'm observing is the same as if I didn't specify the password to login." with an answer referring to our same fix... archive.midrange.com/midrange-l/200601/msg00053.html and archive.midrange.com/midrange-l/200601/msg00065.html Note: It is my experience that FTP questions attract uncouth responses. Admittedly FTP is outdated, but many clients still have legacy systems, which they cannot upgrade or replace. The reason thereof should not be discussed here. The intention of this question is to invite a positive response. Please do not respond if you disagree with the above. If you have never encountered this same issue, please do not respond. I suspect this may be limited to FTP scripts executed from Windows machines, but have been told that this happens often and with many different servers. My specific interest is to understand what may cause this as I have a real world example of a production system suddenly requiring this as a workaround fix, after running for many years without issue. The server belongs to a third party who claims no change on their end. Server details unknown and cannot be determined. Any help or encouragement from someone who has come across the same, would be appreciated. ps. Sorry for the many words and references to painful responses, but I have asked similar questions on serverfault and elsewhere and unfortunately got back kneejerk responses to FTP and respondents debating the validity of the question. I would truly not ask, or re-post this question online if I had a better understanding of the issue. I know of people who have seen this issue, but don't know what causes it. I am wary that this question would again turn into another irrelevant discussion. Please, I ask very nicely: Please do not respond if you have not encountered a similar issue. FURTHER EDIT: Please do not suggest changing the product. The problem is not the blank line requirement. We know this fixes the issue. The problem is not being able to explain the reason for the blank line in the first place. Slight difference, but a critical point to note wrt the answering of this question.

• Updating shared files across computers

  - by murgatroid99

  I have a file server running Windows Server 2008 and a couple of laptops running Windows 7 on a network. There are a large number of files that all users will need access to. My plan is to have the files on both the server and the laptops because the users will need to access the files in places with no Internet access. I also want any changes made to the files on any of the laptops to propagate to the server and then propagate to the other laptops whenever they connect to the network. Should I do this with a scheduled batch script with a few xcopy commands or is there a better way to do it?

• .bat file - Nagios v3.2 service check and start if stopped

  - by LbakerIT

  I'm just barely getting into programming so I do apologize for my ignorance. I'm trying to create a .bat file that will check if a service is running on XP Pro. If service is running it will exit 0. If the service is stopped start service wait 10 seconds (via ping i'm guessing) check if service is running if service is running exit 0 if service is stopped start service wait 10 seconds Do this check a total of 3 times. if service does not come up within that time: exit 2 Exit 0 = ok exit 1 = warning exit 3 = critical (and this will alert) I need to do this for 3 different services but i'm expecting that it would be better to create one per service. That way you get notified on the specific service that is not coming back up. The goal is that if the service stops it will start it. If after 30 seconds it is unable to start the service then it will send an alert. The reason I'm trying to do it with a .bat is this is consistent with all other scripts and I did not want to complicate it further by adding different kinds of code. Yay for consistency! Again I do apologize for my ignorance I've been thrown into this project last minute. Thank you for the help and reading my question!

• How to determine if a bash variable is empty?

• Is there any script to do accounting for the proftpd's xferlog?

  - by Aseques

  I would like to convert from the xferlog format that proftpd uses into per user in/out bytes, to have a summary on how much traffic does each user use per month. The exact format is this: Thu Oct 17 12:47:05 2013 1 123.123.123.123 74852 /home/vftp/doc1.txt b _ i r user ftp 0 * c Thu Oct 17 12:47:06 2013 2 123.123.123.123 86321 /home/vftp/doc2.txt b _ i r user ftp 0 * c So far I only found a script that makes a nice report but not exactly what I needed, that one can be found here I might create a fork of this one and place it somewhere but it probably has been done a lot of times already. Just found a well hidden page in proftpd site with some more examples here

• Different behaviour of script locally and over ssh

  - by neorg

  I have a script on a server-A Script-A #!/bin/bash -l echo "script-A.sh" | change-environment.sh When I ssh onto server-A and execute it, it works fine. However, when I ssh user@server-A ./script-A.sh Script-A executes, but throws an undefined variable error in change-environment.sh. change-environment.sh runs in the c shell(I have no control over the script so the method I have used is about the only way I can use it), but everything else is in bash. Had found a similar question at I can run a script locally, but cannot do "ssh HOSTNAME /path/to/script.sh". However, there was no solution to the issue and it was a year old.

• Run shell script on Linux box from a shortcut/app in Android?

  - by melat0nin

  I have an Ubuntu box which runs XBMC, which crashes occasionally. Since I have no keyboard connected,I have to SSH in, kill xinit, then restart it. I was wondering if there's an elegant way of doing this from my Android tablet, so I don't have to go to my desktop PC. I've used ConnectBot and can log in, but typing is laborious, even using the edit keys to scroll back up through the buffer. It seems as though it should be possible to script this so that I can execute a shortcut, or at least select a predefined script to be executed. This would seem to have plenty of applications, and there could be a site of scripts - restart webserver, reboot, email logs etc

• find directories in the current directory, older than 5 days and archive them

  - by user197284

  This is basic questions. I need to find folders in the current working directory(not recursively) and if they are older than 5 days archive them. zip or tar.gz is fine. I can find the folders with following commands find ./ -maxdepth 1 -type d -mtime +5 And i know i can pass this output of the find using xargs. But i do not know how to archive with folder name intact. That is the directory test1 should be archived to test1.zip and directory "test2" should be archived to "test2.zip". Any inputs are welcome.

• Looking for a powershell script that can pull a file from a set of PC's and FTP

  - by DangeRuss

  I'm looking to write a script (preferably powershell) that will essentially copy a file from a bunch of PC's and FTP it to a server. So the structure of the environment is that we have a file on multiple PC's (around 50 or so) that need to placed on a server. Sometimes one of the PC's may be turned off so the script would first need to ensure the PC is up and running (maybe a ping result), then it would need to go into a directory on that PC, pull a file off of it, rename the file, place into a source directory, then remove the file. Naming convention doesn't matter, but date/time stamp would be easiest. Ideally, it would be best to first move all the files to a source directory to save on FTP bandwidth, but since the files will be named the same, the files must be renamed during the move process. Move not copy because the directory needs to be empty so the file can be re-created the next day. So once moved to the source directory, now all the files need to be FTP'd to a server for processing. After all of this, we need to know which PC's on the list did not respond so we can manually retrieve the file so the script should output a file (txt is fine) that will show which PC's were offline. Everything is one domain and script will be run from an server with admin creds. Thank you!

• Programmatic, script-based, or command line method to change starting program for user on Windows Server 2000/2003?

  - by Joe Majsterski

  I have written an app that we want to distribute to a large number of customers to be used as the shell program when they log onto their server with a particular admin account. I have figured out how to change the starting program by going to Administrative Tools->Computer Management->System Tools->Local Users and Groups->Users, selecting the properties for the user, going to the Environment tab, and changing the program file name under "Starting program" to my new app. But is there a way I could do this with some code that could be sent out and run on all these servers?

• Script to restart BlackBerry services

  - by ICTdesk.net

  Can somebody give me a script advice/example of how to restart services? I have to restart 17 services, but the first 4 services have to be in the right order and after the restart command is given to one of the services, the next one should be started when the previous one is finished. I know I can restart a service by net command, and I can build a delay by for example a ping command that repeats for an x amount of times, but I never know in advance how long it is going to take for a service to restart. Thanks, Kindest regards, Marcel
