  • How to protect Ubuntu from fork bomb

    - by dblang
    I heard someone talking about a fork bomb, I did some research and found some dreadful information about some strange looking characters people can have you type at the command line and as a result do bad things on the computer. I certainly would not issue commands I do not understand but one never knows what can happen. I heard that some OS allows the administrator to place some limit on user processes to mitigate the effects of fork bombs, is this protection in Ubuntu by default or would a person with sudo privilege have to set this? If so, how?

  • Cron doesn't execute one of the scheduled jobs

    - by user288633
    I'm using a lubuntu desktop, distribution Ubuntu 13.10, i686. This is my problem: in the job list scheduled by cron a job hasn't effect, but in /var/log/syslog its execution is traced. This is the relative log line: Jun 4 09:06:01 kiosk CRON[14189]: (root) CMD (/usr/bin/xinput set-prop 12 --type=float "Coordinate Transformation Matrix" 0 -1 1 1 0 0 0 0 1 /tmp/mybackup.log) This job should rotate touchscreen mapping. I try different solutions: I substitute in crontab the with bash -c "", I set "export DISPLAY=:0.0" ("for Graphics related job in Unix Environment we need to set first the DISPLAY...") before the command,...and many other! I know there are a lots of details affect cron execution (path, environment variables, special character and other) and I have no more idea by now :( Could some gentleman suggest me an idea? where can I find the problem? Thanks in advance!

    - by Eonil
    I keep some bash snippets and copy&paste them when I needed for management. But I discovered apt-get cancels script execution. Here's my script where problematic. apt-get -y install gcc g++ make cmake perl cd ~/ mkdir t1 cd t1 I copy & paste this script on OS X Terminal to Ubuntu 12.04 LTS server (fresh install on VM) Script always stop after apt-get finished. I run this command with root account like this. ssh user1@server <password…> sudo su <password…> apt-get -y install gcc g++ make cmake perl cd ~/ mkdir t1 cd t1 Can this be a problem? Or why my script stops after apt-get finished, and how to make it to continue?

  • GNOME Desktop fonts problem debacle

    - by Diogenes Lantern
    I didn't get an answer but I wasn't doing anything and this is an interesting topic. In Ubuntu 12.04, opening a file in gedit or I am working on the command line, in dpkg, I get returned the error "locale not supported, falling back to default "C" libraries", and the one below, Gtk-WARNING **: Locale not supported by C library. Using the fallback 'C' locale. The locales were not set correctly, and locale LANG and LANGUAGE were the culprits. I picked my way through this. The answer, correct below.

  • usb keyboard works except in terminal window (SOLVED)

    - by matrixunloaded
    I just installed 12.10 (clean install and updates). USB keyboard and mouse work fine EXCEPT the keyboard does not work in a terminal window (USB mouse is working in terminal). keyboard is Logitech MK320 and associated mouse. I'm typing in a mozilla window on the keyboard at this very moment and when I switch to the terminal window, nothing can be typed. Any ideas? I use terminal mode alot. Thanks matrixunloaded I didn't realize passwords do not show even an asterisk in terminal mode! I'd just installed 12.10 and was pasting a long sudo command and then typing my password (which looked like nothing appearing)

  • Where does ntpdate get its settings from and what is the "no servers can be used" error about?

    - by wilhil
    When I run ntpdate on its own, I get the following output: 8 Jun 15:47:46 ntpdate[31251]: no servers can be used, exiting If I run it with the -q ntp.ubuntu.com switch, it seems to query just fine. I have been hunting through many files and the most relevant one I have found is /etc/default/ntpdate, however, even with NTPDATE_USE_CONF set to no, I just can't understand/see how this error is occurring Any ideas? Update-- been looking non stop... It appears that ntupdate-debianworks fine and is the actual command that makes use of /etc/default/ntupdate, but, this doesn't answer the main question and I still can't find it...

  • Ubuntu partition won't display on screen

    - by Danny
    I installed ggobi on my MacBook Pro, and it wasn't working right. I looked up some information, and found this site: Gtk Warning: Cannot open display I followed the vague instructions, but I think I just typed export DISPLAY=:0 directly into my terminal (I'm still in my Mac partition at this point). Fast forward a few days, and I try to go into my Ubuntu partition. It only gives me command line options. I remember my reckless input from a few days back, and I'm certain that it is the issue. My problem is that I have no idea how to get my previous display settings back. My Mac partition seems unaffected, but it'd be nice to get back into my Ubuntu partition. My last resort is completely reverting my computer to my most recent backup before I changed it, but if anyone out there knows how to fix this, I'd greatly appreciate it. Thanks in advance.

  • Saving more corsor positions (with tput?) in bash terminal

    - by AndreasT
    I know that tput sc saves the current cursor position and tput rc restores it exactly where tput sc was called. The problem is that every time tput sc is called, it overwrites the previous saved position. Is there a way to save more positions, e.g. tput sc pos1 and tput sc pos2 which can be restored with, say, tput rc pos1 and tput rc pos2 respectively? (The solution need not make use of tput, I mentioned it because it's the only command I know that handles cursor position) If not, is there a way to at least save the cursor position locally in a function, so that if a function uses tput sc and then calls another function that runs again tput sc, then each function restores its own saved cursor position when invoking tput rc? Thanks in advance.

  • Can't copy file (I/O error) Ubuntu Server

    - by QxQ
    I'm running Ubuntu Server 12.04, and basically found out that a couple of files aren't behaving like they should. The file name is r.-1.-1.mca, and I've tried using this terminal command sudo cp r.-1.-1.mca ../ The hard drive is working/thinking for a while, then spits this back out: cp: reading `r.-1.-1.mca': Input/output error cp: failed to extend `../r.-1.-1.mca': Input/output error I have another file behaving like this. My guess is that these files are corrupt, so I tried running the server in recovery mode and it told me to check the file system. However, it didn't come up with any errors. Is there a way to repair these files so I can use them normally again?

  • How to Automatically run two commands after login?

    - by Covi
    I have these two commands that I need to manually run every time after login: autossh -M 2000 -N -f -q -D 127.0.0.1:7070 [email protected] and sudo mkdir /media/C sudo mount /dev/sda2 /media/C I'd like to make them automatically run every time I boot and login to my computer. I'm currently using 10.04LTS. BTW, I only vaguely know what init.d or runlevel mean. But I still prefer to know a command-line based way to achieve this, not a fancy GUI way. Also, the autossh will only succeed after Ubuntu automatically detect and connect to my network, so should we let it retry infinitely until successfully executed? Thank you!

  • What do the various dpkg flags like 'ii' 'rc' mean?

    - by theTuxRacer
    I frequently need to check which packages are installed, and I use the following command: dpkg -l | grep foo which gives the following output Desired=Unknown/Install/Remove/Purge/Hold | Status=Not/Inst/Cfg-files/Unpacked/Failed-cfg/Half-inst/trig-aWait/Trig-pend |/ Err?=(none)/Reinst-required (Status,Err: uppercase=bad) ||/ Name Version Description ii foo <version> <description> What does the ii mean? What other flags are there? How to read the flags? (because the explanation is quite complicated, IMO) Thanks.

  • Upgrade tree to 1.6?

    - by Pureferret
    I'm trying to upgrade my version of tree to 1.6 on ubuntu 12.04. I've d'loaded, ran make and make install in the terminal using the sudo command. ~/tree-1.6.0$ sudo make make: Nothing to be done for `all'. I've already run sudo make here ~/tree-1.6.0$ sudo make install install -d /usr/bin install -d /usr/man/man1 if [ -e tree ]; then \ install -s tree /usr/bin/tree; \ fi install doc/tree.1 /usr/man/man1/tree.1 What's this output though? It's not updated. I've checked the man page, and -du doesn't work. How am I supposed to update tree if not via the terminal?

  • What's the difference between set, export and env and when should I use each?

    - by Oli
    Every so often I'll bash out a bash script and it strikes me there are a few ways of setting a variable: key=value env key=value export key=value When you're inside a script or a single command (for instance, I'll often chain a variable with a Wine launcher to set the right Wine prefix) these seem to be completely interchangeable but surely that can't be the case. What's the difference between these three methods and can you give me an example of when I would specifically want to use each one? Definitely related to What is the difference between `VAR=...` and `export VAR=...`? but I want to know how env fits into this too, and some examples showing the benefits of each would be nice too :)

  • How can I make apt-get wait for another instance to finish?

    - by rajagenupula
    Is there any way I can make apt-get wait for the other apt-get (or similar) processes to finish? I know that, generally, apt-get can only one instance at a time and if we try to run apt-get at the same time then we get a message saying that some other process is using it. My question is: how can I make apt-get wait for the other processes to finish and then run? Advantage: No need to type the command apt-get again, it will be automated after the 1st apt-get finishes.

  • How to create a minimal installation in VMware Player for browsing?

    - by dbz_a
    I am trying to build a minimal vmware image to use for private browsing (also called a browser appliance). I have tried using images for other small linux distros, most of them are either too heavy (I do not want any other functionality than browsing and downloading) or outdated (DSL, various browser appliance images at vmware official site). I have downloaded the minimal Ubuntu install image (12MB) and was hoping to select only the needed pakcages while installing but it was not asking for my choices anywhere. I am new to the command line installation and I would be thankful if someone could point out how to install only needed packages, and what are the bare-minimum packages to browse internet (I plan to use only firefox and transmission)

  • mysql questions for beginners

    - by ankhseeker
    ok, I have a few questions regarding mysql. I am currently running ubuntu 12.04.4 LTS command line version. I am looking for a database that I can use. I am confused at this point because I am uninformed. mysql is just one database that is on the server? or can it contain several or many databases What programs do I use to access it on the server or is it a vt-100 type access? I understand that mysql comes with lamp? or ubuntu. I am thinking that it is already installed but not sure how to access it, but that is another question for later. Outside of the man pages and the ubuntu manual, is there a site for its setup and use? Thanks!

  • Start Activity and clear activity history

    - by sandis
    So I have a huge maze of activities in my application. What I need to do, is that when the user logs in into the system, the activity history should be cleared. I cant just use finish() when I start a new activity, because I want the activities to have a history until the user logs in. I have experimentet with the different flags when starting an activity, but I have had no success. Any ideas? Cheers,

  • SQL Server 2005 Table Alter History

    - by Kayes
    Hi. Does SQL Server maintains any history to track table alterations like column add, delete, rename, type/ length change etc? I found many suggest to use stored procedures to do this manually. But I'm curious if SQL Server keeps such history in any system tables? Thanks.

  • Command history in R

    - by Brani
    Is there any IDE -from the ones supporting R-, that gives access to the command history (at least to the current session's commands)? Or is there a way to get a (character or expression) vector with those commands in R? For those of you that have been using MATLAB, I mean something like the Command History window there.. Thank you

  • How do I remove sensitive files from git's history

    - by Stefan Liebenberg
    I would like to put a git project ( Rails app ) on github, but it contains certian files with sensitive data ( usernames and passwords, like /config/deploy.rb for capistrano ). I know I can add these filenames to .gitignore, but this would not remove the their history within git. I also don't want to start over again by deleting the /.git directory. Is there a way to remove all traces of a particular file in your git history?
