  • How can I close a Window using the OS-X ScriptingBridge framework, from Perl?

    - by Gavin Brock
    Problem... Since MacPerl is no longer supported on 64bit perl, I am trying alternative frameworks to control Terminal.app. I am trying the ScriptingBridge, but have run into a problem passing an enumerated string to the closeSaving method using the PerlObjCBridge. I want to call: typedef enum { TerminalSaveOptionsYes = 'yes ' /* Save the file. */, TerminalSaveOptionsNo = 'no ' /* Do not save the file. */, TerminalSaveOptionsAsk = 'ask ' /* Ask the user whether or not to save the file. */ } TerminalSaveOptions; - (void) closeSaving:(TerminalSaveOptions)saving savingIn:(NSURL *)savingIn; // Close a document. Attempted Solution... I have tried: #!/usr/bin/perl use strict; use warnings; use Foundation; # Load the ScriptingBridge framework NSBundle->bundleWithPath_('/System/Library/Frameworks/ScriptingBridge.framework')->load; @SBApplication::ISA = qw(PerlObjCBridge); # Set up scripting bridge for Terminal.app my $terminal = SBApplication->applicationWithBundleIdentifier_("com.apple.terminal"); # Open a new window, get back the tab my $tab = $terminal->doScript_in_('exec sleep 60', undef); warn "Opened tty: ".$tab->tty->UTF8String; # Yes, it is a tab # Now try to close it # Simple idea eval { $tab->closeSaving_savingIn_('no ', undef) }; warn $@ if $@; # Try passing a string ref my $no = 'no '; eval { $tab->closeSaving_savingIn_(\$no, undef) }; warn $@ if $@; # Ok - get a pointer to the string my $pointer = pack("P4", $no); eval { $tab->closeSaving_savingIn_($pointer, undef) }; warn $@ if $@; eval { $tab->closeSaving_savingIn_(\$pointer, undef) }; warn $@ if $@; # Try a pointer decodes as an int, like PerlObjCBridge uses my $int_pointer = unpack("L!", $pointer); eval { $tab->closeSaving_savingIn_($int_pointer, undef) }; warn $@ if $@; eval { $tab->closeSaving_savingIn_(\$int_pointer, undef) }; warn $@ if $@; # Aaarrgghhhh.... As you can see, all my guesses at how to pass the enumerated string fail. Before you flame me... I know that I could use another language (ruby, python, cocoa) to do this but that would require translating the rest of the code. I might be able to use CamelBones, but I don't want to assume my users have it installed. I could also use the NSAppleScript framework (assuming I went to the trouble of finding the Tab and Window IDs) but it seems odd to have to resort to it for just this one call.

  • Log errors in a file

    - by Konstantin
    How do I log all process crashes into a file instead of a tty ? I've read in the documentation that there are some standard Erlang modules that can do it (SASL, error_logger), but unfortunately haven't found any clean examples.

  • LightDM will not start after stopping it

    - by Sweeters
    I am running Ubuntu 11.10 "Oneiric Ocelot", and in trying to install the nvidia CUDA developer drivers I switched to a virtual terminal (Ctrl-Alt-F5) and stopped lightdm (installation required that no X server instance be running) through sudo service lightdm stop. Re-starting lightdm with sudo service lightdm start did not work: A couple of * Starting [...] lines where displayed, but the process hanged. (I do not remember at which point, but I think it was * Starting System V runlevel compatibility. I manually rebooted my laptop, and ever since booting seems to hang, usually around the * Starting anac(h)ronistic cron [OK] log line (not consistently at that point, though). From that point on, I seem to be able to interact with my system only through a tty session (Ctrl-Alt-F1). I've tried purging and reinstalling both lightdm and gdm, as well as selecting both as the default display managers (through sudo dpkg-reconfigure [lightdm / gdm] or by manually editing /etc/X11/default-display-manager) through both apt-get and aptitude (that shouldn't make a difference anyway) after updating the packages, but the problem persists. Some of the responses I'm getting are the following: After running sudo dpkg-reconfigure lightdm (but not ... gdm) I get the following message: dpkg-maintscript-helper:warning: environment variable DPKG_MATINSCRIPT_NAME missing dpkg-maintscript-helper:warning: environment variable DPKG_MATINSCRIPT_PACKAGE missing After trying sudo service lightdm start or sudo start lightdm I get to see the boot loading screen again but nothing changes. If I go back to the tty shell I see lightdm start/running, process <num> but ps -e | grep lightdm gives no output. After trying sudo service gdm start or sudo starg gdm I get the gdm start/running, process <num> message, and gdm-binary is supposedly an active process, but all that happens is that the screen blinks a couple of times and nothing else. Other candidate solutions that I'd found on the web included running startx but when I try that I get an error output [...] Fatal server error: no screens found [...]. Moreover, I made sure that lightdm-gtk-greeter is installed but that did not help either. Please excuse my not including complete outputs/logs; I am writing this post from another computer and it's hard to manually copy the complete logs. Also, I've seen several posts that had to do with similar problems, but either there was no fix, or the one suggested did not work for me. In closing: Please help! I very much hope to avoid re-installing Ubuntu from scratch! :) Alex @mosi I did not manage to fix the NVIDIA kernel driver as per your instructions. I should perhaps mention that I'm on a Dell XPS15 laptop with an NVIDIA Optimus graphics card, and that I have bumblebee installed (which installs nvidia drivers during its installation, I believe).

  • Execute a remote command after sudo - su anotheruser in Rundeck

    - by Bera
    I'm new with Rundeck and completely amazed with it and I'm trying to execute a job and my scenario is detailed below: Rundeck is configured with ssh passwordless authentication for user master between node Server (rundeck server) and node Target (remote Solaris host) for user "master" In node Target I want to execute a script /app/acme/stopApp.sh with a user appmanager Normally and manually, when I need to run script above I proceed with ssh master@server sudo su - appmanager or simply ssh -t master@server 'sudo su - appmanager' works without password and finally run (as appmanager) /app/acme/stopApp.sh But I'm not sure how can I reproduce these steps using Rundeck. I read in some previous messages that for each job line rundeck use a new ssh connection, so the workflow below always fails for me with the messages: sudo: no tty present and no askpass program specified Remote command failed with exit status 1 Please someone could help me with some information to solve this issue. Without this functionality I wouldn't be able to introduce a little DevOps in my department. I read the user guide and admin guide but I couldn't find an easy example, neither in this forum, to follow.

Ssl 22:09 0:00 /usr/sbin/named I'm not running any java applications so I'm not sure why the top issue is showing up. It is frustrating as I barely have anything running on the server and use the tiniest fraction of bandwidth. Any help or suggestions on zeroing in on the source of the drain would be much appreciated! Thanks!

  • How can I use scp without providing a password

    - by Tim
    I have asked a question before in here. My question was that I tried to give my password to scp via piping echo mypassword | scp [email protected]:project/* ~/project/ However it still asks me to manually input the password. How should I specify mypassword to scp in commands? I still don't understand one of the replies. what is a input stream by TTY, for example? What are the common ways for a input stream? How to know what type of input stream a stdin input to a command is? For example that of ssh/scp.

  • Cleaning Up Unused Users and Groups (Ubuntu 10.10 Server)

    - by PhpMyCoder
    Hello experts, I'm very much a beginner when it comes to Ubuntu and I've been learning the ropes by diving in and writing a (backend-language independent) web app framework that relies on apache, some clever mod_rewrites, Ubuntu permissions, groups, and users. One thing that really annoys my inner clean-freak is that there are loads of users and groups that are created when Ubuntu is installed that are never used (Or so I think). Since I'm just running a simple web app server, I would like to know: What users/groups can I remove? Since you'll probably ask for it...here's a list of all the users on my box (excluding the ones I know that I need): root daemon bin sys sync man lp mail uucp proxy backup list irc gnats nobody libuuid syslog And a list of all of the groups: root daemon bin sys adm tty disk lp mail uucp man proxy kmem dialout fax voice cdrom floppy tape sudo audio dip backup operator list irc src gnats shadow utmp video sasl plugdev users nogroup libuuid crontab syslog fuse mlocate ssl-cert lpadmin sambashare admin

  • Why doesn't my environment variable get set?

    - by reprogrammer
    I have to set an environment variable called GDK_NATIVE_WINDOWS to fix the problem with Eclipse buttons in Ubuntu. To set the environment variable, I added the following line to ~/.pam_environment. GDK_NATIVE_WINDOWS DEFAULT=true Surprisingly, the environment variable doesn't get set when I echo $GDK_NATIVE_WINDOWS in a terminal. However, all other environment variables that I've listed in ~/.pam_environment are set properly. Besides, when I switch to a tty, e.g. Alt+Ctrl+F1, the environment variable gets set correctly. Can anyone tell what's wrong with setting this environment variable in ~/.pam_environment?

  • Other user SSHed from my hardware

    - by Alex
    While logged into our HPC cluster I used w to check out who else was logged in. I happened to notice that it looks like there's another user logged in from my (personal) computer; 19:04:47 up 40 days, 6:39, 44 users, load average: 0.10, 0.14, 0.18 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT ME pts/4 zerg.neuron12. 18:55 0.00s 0.09s 0.04s w SOMEONE_ELSE pts/35 zerg.neuron12. Sat14 2:27m 0.08s 0.08s -bash Is this something I should be worried out - I tried to kill the other session but had a permission denied message. Is it possible we just both have the same hardware name? I'd have thought that if this were the case the server would give one of us a different name (e.g. zerg1) when we logged in to prevent confusion. This is not an area I have any experience with, so any advice would be greatly appreciated!

  • Error installing Arch Linux

    - by Garethj94
    So, I am trying to install Arch Linux on my Acer Aspire 4830tg, but I keep running into problems. Some background knowledge, I am trying to install Arch off a usb stick and I got the iso image using bittorrent. I am also trying to install it alongside of Windows 8 (which is already installed). So when I boot into Arch linux I get this error: :: Mounting '/dev/disk/by-label/ARCH_201212' to 'run/archiso/bootmnt' Waiting 30 seconds for device /dev/disk/by-label/ARCH_201212 ... ERROR: '/dev/disk/by-label/ARCH_201212' device did not show up after 30 seconds... Falling back to interactive prompt You can try to fix the problem manually, log out when you are finished sh: can't access tty; job control turned off I know that it will work if I run it on a virtual machine but whenever I try to install it on my laptop I keep getting this error. And since you can't register for the Arch forums without a Arch terminal to run their captcha command I can't ask this on their forums.

  • Wiping out user and/or root password in embedded linux

    - by TryTryAgain
    We have a security camera system running an embedded linux. It boots with Lilo as a bootloader and has no tty access once booted. I don't know any username either. SSH/22 is open, but I don't think brute force is an option. I have tried all the common tricks to reset a linux user password (boot from the bootloader in single user mode = doesn't happen, still prompts for user login, boot to a live cd = can't access the file system...it's all loop files and other binary, etc etc), but they are all not possible as it is an embedded linux setup the way it is. Any help/suggestions would be appreciated. Thanks

  • Is there a serious issue with setting the SUID bit on tcpdump?

    - by Dean
    I'm running tcpdump on a remote machine, and piping the output to Wireshark on my local machine over SSH. In order to do this, I had to set the SUID bit on tcpdump. For background, the remote machine is an Amazon EC2 running "Amazon Linux AMI 2012.09". On this image, there is no root password, and it is not possible to log in as root. You can't use sudo without a TTY, and therefore you have to set the SUID. What are the practical risks of setting this bit on tcpdump? Is there any need to be paranoid? Should I unset it whenever I'm not capturing?

  • linux audit - exclude a process that updates the time

    - by user185704
    I have set my auditd rules to log when the system time is changed However, our servers are VMs and thus have problems with the time drifting out. We needed to solve this issue so we used a VMware tool to regularly synchronize the time. My problem now is that my audit logs are overwhelmed with time change entries like this: Jun 1 15:08:39 ***** audispd: node=****** type=SYSCALL msg=audit(1338559719.053:344291): arch=c000003e syscall=159 success=yes exit=5 a0=7ffff2084050 a1=0 a2=144b a3=485449575f4c4c55 items=0 ppid=1 pid=1348 auid=4294967295 uid=0 gid=0 euid=0 suid=0 fsuid=0 egid=0 sgid=0 fsgid=0 tty=(none) ses=4294967295 comm="vmtoolsd" exe="/usr/lib/vmware-tools/bin64/appLoader" key="time_change" How can I exclude this vmware tool from the audit, but still capture a user changing the time?

  • Can't log in via SSH to any accounts set to use /bin/bash as a default shell

    - by Gui Ambros
    I'm trying to install bash as the default shell on a ARM Linux running on an embedded device (Synology DS212+ NAS). But there's something really wrong, and I can't figure out what it is. Symptoms: 1) Root has /bin/bash as default shell, and can log in normally via SSH: $ grep root /etc/passwd root:x:0:0:root:/root:/bin/bash $ ssh root@NAS root@NAS's password: Last login: Sun Dec 16 14:06:56 2012 from desktop # 2) joeuser has /bin/bash as default shell, and receives "Permission denied" when trying to log in via SSH: $ grep joeuser /etc/passwd joeuser:x:1029:100:Joe User:/home/joeuser:/bin/bash $ ssh joeuser@localhost joeuser@NAS's password: Last login: Sun Dec 16 14:07:22 2012 from desktop Permission denied, please try again. Connection to localhost closed. 3) changing joeuser's shell back to /bin/sh: $ grep joeuser /etc/passwd joeuser:x:1029:100:Joe User:/home/joeuser:/bin/sh $ ssh joeuser@localhost Last login: Sun Dec 16 15:50:52 2012 from localhost $ To make things even more strange, I can log in as joeuser using /bin/bash using the serial console (!). Also a su - joeuser as root works fine, so the bash binary itself is working fine. In an act of despair, I changed joeuser's uid to 0 on /etc/passwd, but also didn't work, so it doesn't seem to be anything permission related. Seems that bash is doing some extra checking that sshd didn't like, and blocking the connections for non-root users. Maybe some sort of sanity checking - or terminal emulation - that is triggering the SIGCHLD, but only when called via ssh. I already went through every single item on sshd_config, and also put SSHD in debug mode, but didn't find anything strange. Here's my /etc/ssh/sshd_config: LogLevel DEBUG LoginGraceTime 2m PermitRootLogin yes RSAAuthentication yes PubkeyAuthentication yes AuthorizedKeysFile %h/.ssh/authorized_keys ChallengeResponseAuthentication no UsePAM yes AllowTcpForwarding no ChrootDirectory none Subsystem sftp internal-sftp -f DAEMON -u 000 And here's the output from /usr/syno/sbin/sshd -d, showing the failed attempt of joeuser trying to log in, with /bin/bash as the shell: debug1: Config token is loglevel debug1: Config token is logingracetime debug1: Config token is permitrootlogin debug1: Config token is rsaauthentication debug1: Config token is pubkeyauthentication debug1: Config token is authorizedkeysfile debug1: Config token is challengeresponseauthentication debug1: Config token is usepam debug1: Config token is allowtcpforwarding debug1: Config token is chrootdirectory debug1: Config token is subsystem debug1: HPN Buffer Size: 87380 debug1: sshd version OpenSSH_5.8p1-hpn13v11 debug1: read PEM private key done: type RSA debug1: private host key: #0 type 1 RSA debug1: read PEM private key done: type DSA debug1: private host key: #1 type 2 DSA debug1: read PEM private key done: type ECDSA debug1: private host key: #2 type 3 ECDSA debug1: rexec_argv[0]='/usr/syno/sbin/sshd' debug1: rexec_argv[1]='-d' Set /proc/self/oom_adj from 0 to -17 debug1: Bind to port 22 on ::. debug1: Server TCP RWIN socket size: 87380 debug1: HPN Buffer Size: 87380 Server listening on :: port 22. debug1: Bind to port 22 on 0.0.0.0. debug1: Server TCP RWIN socket size: 87380 debug1: HPN Buffer Size: 87380 Server listening on 0.0.0.0 port 22. debug1: Server will not fork when running in debugging mode. debug1: rexec start in 6 out 6 newsock 6 pipe -1 sock 9 debug1: inetd sockets after dupping: 4, 4 Connection from 127.0.0.1 port 52212 debug1: HPN Disabled: 0, HPN Buffer Size: 87380 debug1: Client protocol version 2.0;
