• Apple: Bind a key to a commandline command?

  - by Stefan Lasiewski

  I have a Mac Powerbook running Leopard (10.5.8). Does Leopard provide an easy way to bind keys to commands which are typically run on the commandline? For example, I can open up Terminal.app and run the command /System/Library/Frameworks/ScreenSaver.framework/Resources/ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine which will activate the screensaver and lock my screen. What if I want to bind 'Apple-key L' to this command and execute this globally, regardless of which application is in use at the moment? Can I do this, or can I only run ScreenSaverEngine from a Terminal window? I tried to set up global keyboard shortcuts, but it seems that this won't allow me to bind a key to an arbitrary shell command: Note: You can create keyboard shortcuts only for existing menu commands. You cannot define keyboard shortcuts for general purpose tasks such as opening an application or switching between applications. I tried to set up a application keyboard shortcut, but commands like ScreenSaverEngine don't seem to be an application. Note that this Screensaver/Lock screen is just one example. I have come across other nifty commands which I might want to bind to a key-combination as well. I can do this in Gnome and Windows (with varying success). How about with Leopard?

• How to encourage Windows administrators to pick up scripting

  - by icelava

  When i worked as an administrator in my first job, I was frustrated 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?

• GlassFish v2.1 -- getting Application Client and Eclipselink to work together?

  - by Nick

  We are trying to use Eclipselink 1.1 with Glassfish v2.1. Following the instructions on: http://wiki.glassfish.java.net/Wiki.jsp?page=FaqEclipseLinkGlassFishV2 I adapted the instructions for the appclient script on linux by adding the lines: APPCPATH=$APPCPATH:$AS_INSTALL/lib/eclipselink-1.1.1.jar export APPCPATH to the appclient shell script. This however is not working. On running the application client (using Glassfish's webstart), I get the error: WARNING: "IOP00810257: (MARSHAL) Could not load class org.eclipse.persistence.indirection.IndirectList" Anyone else succeed in getting GF v 2.1 to work with eclipselink? or any ideas on what I might be doing wrong? I found this bug report: http s://glassfish.dev.java.net/issues/show_bug.cgi?id=8204 (New users can't post more than 1 link, so remove the space between 'http' and 's'.) Where Tim Quinn (tjquinn) said: App client container support for persistence is not yet in place I think this refers only to Glassfish v3, and it should be working in Glassfish v2. Is this correct? I'm working on the assumption that this will work once the ACC knows where to find the eclipselinks jar. Thanks in advance, Nick.

• Reading log files from web application

  - by Egorinsk

  I want to write a small PHP application for monitoring logs on a Debian server, including syslog logs and Apache/PHP messages. The problem here is that Apache user (www-data) has no access to /var/log directory. What would be the best way to grant an access to logs for PHP application? Let's assume that log files can be really large, like hundreds of megabytes. I have some ideas: Write a shell script that would be run via sudo and tail last 512 Kb of log into a separate file that can be read by application - that's ineffective, because of forking a new process and having to read data twice Add www-data to adm group (that can read logs) - that's insecure Start a PHP process via cron every minute to read logs — that's not very good, because it doesn't allow real-time monitoring. Also, this script will be started even when I don't read logs, and consume CPU time (server is in the cloud, and I'll have to pay for it) Create a hardlink for all log files with lowered permissions - I guess, that won't work because logrotate could recreate log files and they'll change inode number. Start a separate nginx/Apache server under privileged user that may read logs. Maybe anyone got a better solution?

• Run GUI application via cronjob in Ubuntu?

  - by Christoffer

  Hi, I have a remote server running "Ubuntu 10.04 Desktop". From it I want to run a script that walks through a list of websites and captures screenshots of them. The script is working and thoroughly tested. When I SSH to the server with ssh -X user@ip-adress I can run my script by calling ./myscript.py and everything will work OK. I then modifed my crontab file and added... 59 17 * * * env DISPLAY=:0 /path/to/myscript.py ...as recommended by the Ubuntu WIKI. I can see in the /var/log/syslog that my cron job is started, but it doesn't capture any screenshots. When running env DISPLAY=:0 /path/to/myscript.py from the shell I get No protocol specified myscript.py: cannot connect to X server :0 If I ssh to the server without the -X option I only get the second row of the error: myscript.py: cannot connect to X server :0 What can I try now? More details I have run xhost +local: and checked the output of xhost to see that the option was set correctly. If I run ls /tmp/.X11-unix/ the output is X0 The server only has one screen. Thank you in advance!

• Access NFS share from cygwin?

  - by Jason Voegele

  We have a Windows 2003 Server on which we have installed Microsoft's Services for UNIX, and we have mounted a few NFS shares that contain shared resources that we need to access from this box. When I log in to this server with remote desktop, I am able to browse the contents of the NFS shares and everything works fine. However, one use case that we have is that we need to access this server using SSH, and still be able to access the NFS shares. We are running the Cygwin SSH daemon to provide SSH access to the server, but for some reason when we log in to the Windows 2003 server using SSH we can no longer access the NFS shares. To demonstrate, here is the output of the 'mount' command, first from a Cygwin shell when logged in with remote desktop: $ mount C:/cygwin/bin on /usr/bin type ntfs (binary,auto) C:/cygwin/lib on /usr/lib type ntfs (binary,auto) C:/cygwin on / type ntfs (binary,auto) C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto) O: on /cygdrive/o type nfs (binary,posix=0,user,noumount,auto) P: on /cygdrive/p type nfs (binary,posix=0,user,noumount,auto) Z: on /cygdrive/z type nfs (binary,posix=0,user,noumount,auto) And now, the same 'mount' command when logged in with SSH: $ mount C:/cygwin/bin on /usr/bin type ntfs (binary,auto) C:/cygwin/lib on /usr/lib type ntfs (binary,auto) C:/cygwin on / type ntfs (binary,auto) C: on /cygdrive/c type ntfs (binary,posix=0,user,noumount,auto) Notice the missing O: P: and Z: NFS shares in the latter. Can anyone tell me why I am unable to see these NFS shares when logged in with SSH? Thanks!

• How do I get ftype & assoc to match Windows Explorer?

  - by Gauthier

  I changed the association to use upon launching a .py file, via Windows Explorer: Tools - Folders - File types. Then browse to .py. Change the association to Wordpad. Now when I type the name of a py file in the command line, Wordpad opens it. But assoc and ftype in the command line still return the following: C:\> assoc .py .py = Python.File C:\> ftype Python.File Python.File = "C:\Program\Python27\python.exe" "%1" %* How come the association is working, but assoc and ftype are not aware of it? I did restart the prompt. More info from my registry: HKEY_CLASSES_ROOT\.py = Python.File HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.py\Application = wordpad.exe HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Explorer\FileExts\.py\OpenWithProgids\Python.File = HKEY_LOCAL_MACHINE\SOFTWARE\Classes\.py\(Standard) = Python.File More registry: HKEY_CLASSES_ROOT\Applications\python.exe\shell\open\command\(Standard) = "C:\Program\Python27\python.exe" "%1" %*` I suppose this is what is showing up in ftype Python.File. But it does not seem to get used. (I am doing this for testing, so I can eventually choose my default version of Python easily).

• Git clone/pull across local network

  - by Tom Sarduy

  I'm trying to clone/pull a repository in another PC using Ubuntu Quantal. I have done this on Windows before but I don't know what is the problem on ubuntu. I tried these: git clone file:////pc-name/repo/repository.git git clone file:////192.168.100.18/repo/repository.git git clone file:////user:pass@pc-name/repo/repository.git git clone smb://c-pc/repo/repository.git git clone //192.168.100.18/repo/repository.git Always I got: Cloning into 'intranet'... fatal: '//c-pc/repo/repository.git' does not appear to be a git repository fatal: The remote end hung up unexpectedly or fatal: repository '//192.168.100.18/repo/repository.git' does not exist More: The other PC has username and password Is not networking issue, I can access and ping it. I just installed git doing apt-get install git (dependencies installed) I'm running git from the terminal (I'm not using git-shell) What is causing this and how to fix this? Any help would be great! UPDATE I have cloned the repo on Windows using git clone //192.168.100.18/repo/intranet.git without problems. So, the repo is accessible and exist! Maybe the problem is due user credentials?

• Ubuntu 9.10 RSA authentication: ssh fails, filezilla runs fine

  - by MariusPontmercy

  This is quite a mistery for me. I usually use passwordless RSA authentication to login into my remote *nix servers with ssh and sftp. Never had any problem until now. I cannot connect to an Ubuntu 9.10 machine: user@myclient$ ssh -i .ssh/Ganymede_key [email protected] [...] debug1: Host 'ganymede.server.com' is known and matches the RSA host key. debug1: Found key in /home/user/.ssh/known_hosts:14 debug2: bits set: 494/1024 debug1: ssh_rsa_verify: signature correct debug2: kex_derive_keys debug2: set_newkeys: mode 1 debug1: SSH2_MSG_NEWKEYS sent debug1: expecting SSH2_MSG_NEWKEYS debug2: set_newkeys: mode 0 debug1: SSH2_MSG_NEWKEYS received debug1: SSH2_MSG_SERVICE_REQUEST sent debug2: service_accept: ssh-userauth debug1: SSH2_MSG_SERVICE_ACCEPT received debug2: key: .ssh/Ganymede_key (0xb96a0ef8) debug2: key: .ssh/Ganymede_key ((nil)) debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Next authentication method: publickey debug1: Offering public key: .ssh/Ganymede_key debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: publickey,password,keyboard-interactive debug1: Trying private key: .ssh/Ganymede_key debug1: read PEM private key done: type RSA debug2: we sent a publickey packet, wait for reply debug1: Authentications that can continue: publickey,password,keyboard-interactive debug2: we did not send a packet, disable method debug1: Next authentication method: keyboard-interactive debug2: userauth_kbdint debug2: we sent a keyboard-interactive packet, wait for reply debug2: input_userauth_info_req debug2: input_userauth_info_req: num_prompts 1 Then it falls back to password authentication. If I disable password authentication on the remote machine my connection attempt just fails with a "Permission denied (publickey)." state. Same thing for sftp from command line. The "funny" thing is that the exact same RSA key works like a charm with a Filezilla sftp session instead: 12:08:00 Trace: Offered public key from "/home/user/.filezilla/keys/Ganymede_key" 12:08:00 Trace: Offer of public key accepted, trying to authenticate using it. 12:08:01 Trace: Access granted 12:08:01 Trace: Opened channel for session 12:08:01 Trace: Started a shell/command 12:08:01 Status: Connected to ganymede.server.com 12:08:02 Trace: CSftpControlSocket::ConnectParseResponse() 12:08:02 Trace: CSftpControlSocket::ResetOperation(0) 12:08:02 Trace: CControlSocket::ResetOperation(0) 12:08:02 Status: Retrieving directory listing... 12:08:02 Trace: CSftpControlSocket::SendNextCommand() 12:08:02 Trace: CSftpControlSocket::ChangeDirSend() 12:08:02 Command: pwd 12:08:02 Response: Current directory is: "/root" 12:08:02 Trace: CSftpControlSocket::ResetOperation(0) 12:08:02 Trace: CControlSocket::ResetOperation(0) 12:08:02 Trace: CSftpControlSocket::ParseSubcommandResult(0) 12:08:02 Trace: CSftpControlSocket::ListSubcommandResult() 12:08:02 Trace: CSftpControlSocket::ResetOperation(0) 12:08:02 Trace: CControlSocket::ResetOperation(0) 12:08:02 Status: Directory listing successful Any thoughts?

• Moving hidden files/folders with the command-line or batch-file

  - by Synetech

  Question Does anyone know of a way to move files and folders that have the hidden, system, or read-only attribute set from the command-line or a batch file? (No, stripping the attributes first is not an option since there is no practical way to know which attributes were set in order to re-set them after the move.) (Failed) Attempts Using the basic move command does not work with items with the hidden or system attribute set and for some reason, it does not have switches to specify attributes like the dir and del commands do. I tried using a utility I wrote that uses the shell’s file operation function, but that requires using start /w to prevent the batch file from running on ahead, and it complains about long-filename support for some reason. I tried using robocopy, but it first copies the files and then deletes the originals instead of simply moving the source (which results in a frustrating delay, even with the excessive output redirected to nul). (Surprisingly it seems that few people have ever needed to move hidden files from the command-line. All I could find was this one person who abandoned the attempt.)

• How to avoid sshfs freezing?

  - by Andreas Hagen

  So the issue is this: I've installed sshfs on Ubuntu 12.04 and I'm trying to connect to a couple of remote servers. So initially the mount seams successful. Sometimes Gnome even picks it up and displays the "new device found" box at the bottom of the screen. but from here on there is not much that works. Or at least not any more. The first couple of times i connected it seamed to work fine, and I was able to transfer some files, then i disconnected using fusermount -u <folder> and after reconnecting a little later the trouble started. Now after executing sshfs -o ServerAliveInterval=15 -o reconnect -C -o workaround=all -o idmap=user root@<host>:/ <folder>, when I change directory into the mount-point, the shell just freezes. Strangely ls -al <folder> works when listing just the root of the remote system, but nothing more. Also every file-explorer I've tried freezes just like cd <folder>. To me it seamed like there was some kind of zombie thread or something hanging around my system, due to the fact that it did work the first time, so I have tried rebooting but no luck. sshfs -V gives this: SSHFS version 2.3 FUSE library version: 2.8.6 fusermount version: 2.8.6 using FUSE kernel interface version 7.12 So yea, any ideas?

• Is there a faster way to change default apps associated with file types on OS X?

  - by Lri

  Is there anything more convenient than using RCDefaultApp or Magic Launch, or just repeatedly pressing the Change All buttons in Finder's information panels? I thought about writing a shell script that would modify the CFBundleDocumentTypes arrays in Info.plist files. But each app has multiple keys (sometimes an icon) that would need to be changed. lsregister can't be used to make specific modifications to the Launch Services database. $ `locate lsregister` -h lsregister: [OPTIONS] [ <path>... ] [ -apps <domain>[,domain]... ] [ -libs <domain>[,domain]... ] [ -all <domain>[,domain]... ] Paths are searched for applications to register with the Launch Service database. Valid domains are "system", "local", "network" and "user". Domains can also be specified using only the first letter. -kill Reset the Launch Services database before doing anything else -seed If database isn't seeded, scan default locations for applications and libraries to register -lint Print information about plist errors while registering bundles -convert Register apps found in older LS database files -lazy n Sleep for n seconds before registering/scanning -r Recursive directory scan, do not recurse into packages or invisible directories -R Recursive directory scan, descending into packages and invisible directories -f force-update registration even if mod date is unchanged -u unregister instead of register -v Display progress information -dump Display full database contents after registration -h Display this help

• Migrating JBoss installation and install it on a PHP server

  - by David Martinez

  I'm configuring a new dedicated server that is going to run 3 sites, 2 of then are migrating from a old server. Each site have it's own domain and dedicated ip. 2 of this sites are already up and running on php (one of then use cakePHP), the third site is a migration from an old server and it runs on JBoss. 1) Is it possible to have both Jboss and php running on the same Apache instance, or would I have to install a new one? 2) Can I just move the old JBoss server directory to the new server and start the server with the shell script? From what I red here JBoss is distributed as a zip/tgz file with the server structure, so moving it from the old server to the new one should be the same. I want to do this because the old server is already configured, and it have 2 JBoss instances. I didn't develop this site and I don't have experience with JBoss. I have some documentation of the site, but it is not much, mostly server structure and the technology they used. The new server runs on CentOS with CPanel, I have full root access to the server. This question is similar to this one How can I run JBoss Application Server and Apache on the same server? but there he didn't have a dedicated IP for each domain.

• Cisco ASA user authentication options - OpenID, public RSA sig, others?

  - by Ryan

  My organization has a Cisco ASA 5510 which I have made act as a firewall/gateway for one of our offices. Most resources a remote user would come looking for exist inside. I've implemented the usual deal - basic inside networks with outbound NAT, one primary outside interface with some secondary public IPs in the PAT pool for public-facing services, a couple site-to-site IPSec links to other branches, etc. - and I'm working now on VPN. I have the WebVPN (clientless SSL VPN) working and even traversing the site-to-site links. At the moment I'm leaving a legacy OpenVPN AS in place for thick client VPN. What I would like to do is standardize on an authentication method for all VPN then switch to the Cisco's IPSec thick VPN server. I'm trying to figure out what's really possible for authentication for these VPN users (thick client and clientless). My organization uses Google Apps and we already use dotnetopenauth to authenticate users for a couple internal services. I'd like to be able to do the same thing for thin and thick VPN. Alternatively a signature-based solution using RSA public keypairs (ssh-keygen type) would be useful to identify user@hardware. I'm trying to get away from legacy username/password auth especially if it's internal to the Cisco (just another password set to manage and for users to forget). I know I can map against an existing LDAP server but we have LDAP accounts created for only about 10% of the user base (mostly developers for Linux shell access). I guess what I'm looking for is a piece of middleware which appears to the Cisco as an LDAP server but will interface with the user's existing OpenID identity. Nothing I've seen in the Cisco suggests it can do this natively. But RSA public keys would be a runner-up, and much much better than standalone or even LDAP auth. What's really practical here?

• Juniper NetScreen NS-5GT traffic monitoring

  - by blah

  I've done casual research into the subject and am truly dismayed at the lack of compatible tools for such a simple task. Maybe someone can provide assistance. We have a NetScreen NS-5GT in the office. I need to be able to get a glance of current traffic per endpoint -- I think the equivalent of 'get sessions' with byte counts/rates. I don't care about bars, graphs, and reports. Something as simple as a classic software firewall display would be perfect. I can't shell out money on something real like SolarWinds products, so a free solution is essential. I'm willing to do a little work but refuse to program something from scratch. It's not prudent right now for me to install a hub or otherwise mess around physically. There must be something out there I can use, maybe in combination. I don't believe I'm asking too much. Specific answers only please, e.g. monitoring software you know will actually work with this antiquated device. I've read about general approaches to the broader problem dozens of times already.

• kde dropping keyboard

  - by shabbychef

  I am having problems with KDE 'dropping' my keyboard. It happens periodically when using my gentoo box directly, but has become much worse when accessing via NX (from a Mac laptop). Some possibly irrelevant clues: it appears to happen more often when the system is under higher CPU load the mouse continues to work, but no windows will accept any kind of keyboard focus. kwin will not accept tabbing between windows. when working on the machine directly, I can ctrl-alt-F1 to get to a shell (obviously this does nothing over NX). so I think it is KDE and not xorg. am running kwin-4.3.5-r1, and KDE-4.3.5 generally. this problem definitely appeared after upgrading to kde-4.x, but I do not remember if it appeared in kde-4.2. sometimes the keyboard will reappear, but sometimes I have to kill my kde session. playing with accessibility options or window-focus-stealing options in system-settings under kde will often make the keyboard responsive again, only to drop it perhaps minutes later. I had read online this might be an evdev problem under X (again, I think this is KDE, not X, but will try anything). as a result, I have fiddled with my xorg.conf endlessly. I even deleted it entirely and let nvidia-xconfig have a stab at it, with no luck I am tearing my hair out over this. I have done emerge -e xorg-server and am right now doing emerge -e kwin, to rebuild all packages that might be relevant. no luck with the xorg-server rebuild. any help appreciated. thanks,

• Scripting a permanent CTRL / CAPS swap in Gnome?

  - by Duncan Bayne

  I have a bash script that I use to configure a vanilla Ubuntu (10.10 Maverick Meerkat) installation to be exactly the way I want it. I make extensive use of gconftool-2 to configure the desktop, set up shortcut keys, etc. Now, I'm trying to swap the CTRL and CAPS keys. I have found two ways of doing this: In Gnome, go to System - Preferences - Keyboard - Layout - Options and make the change in there. This works well, but I don't know how to script this; the setting doesn't seem to be stored in the usual place as I can't find it with gconf-editor. Add the line setxkbmap -option "ctrl:swapcaps" to my .bashrc file. That works too, until I suspend the machine & then resume it. At that point the CTRL and CAPS behaviour return to normal, until I cause .bashrc to be run again by opening a new shell. This behaviour has been reported as a bug in RedHat. Could someone please suggest a way of switching those keys that is both permanent, and can be scripted? I'm sure I must be missing something obvious here ...

• Set primary group of file or directory on Samba share from Windows

  - by Hubert Kario

  Short version: I have such situation on a Samba share: $ ls -lha total 12K drwxr-xr-x 3 hka Domain Users 4.0K Jan 11 17:07 . drwxrwxrwt 19 root root 4.0K Jan 11 17:06 .. drwxr-xr-x 2 hka Domain Users 4.0K Jan 11 17:07 dir A -rw-r--r-- 1 hka Domain Users 0 Jan 11 17:07 file A How am I able to change this to following using only Windows SMB/CIFS client (using 3rd party applications is OK) $ ls -lha total 12K drwxr-xr-x 3 hka Domain Users 4.0K Jan 11 17:07 . drwxrwxrwt 19 root root 4.0K Jan 11 17:06 .. drwxr-xr-x 2 hka ntpoweruser 4.0K Jan 11 17:07 dir A -rw-r--r-- 1 hka ntpoweruser 0 Jan 11 17:07 file A Rationale and background info I'm using POSIX ACLs on Samba shares. Together with acl group control for Samba, it allows me to delegate management of permissions to different users based on group membership. Thing is, when I create a new file on a Samba share, I'm unable to set its primary group (the one that grants permission to change its permissions). It's being set to my primary group (Domain Users) or group set using force group option in smb.conf share definition. Removing all groups in windows except the one I want to become the new primary group doesn't work. I can change it using chgrp group folder/ as regular user though shell, but it's suboptimal (not all users are *nix users). Trying to set new owner to group from Windows file permission window makes the Samba to return permission denied with following log entry: [2012/01/05 21:13:03.349734, 3] smbd/nttrans.c:1899(call_nt_transact_set_security_desc) call_nt_transact_set_security_desc: file = projects/project A/New folder, sent 0x1 [2012/01/05 21:13:03.349774, 3] smbd/posix_acls.c:1208(unpack_nt_owners) unpack_nt_owners: unable to validate owner sid for S-1-5-21-4526631811-884521863-452487935-11025 [2012/01/05 21:13:03.349804, 3] smbd/error.c:80(error_packet_set) error packet at smbd/nttrans.c(1909) cmd=160 (SMBnttrans) NT_STATUS_INVALID_OWNER The SID is correct and belongs to group I specified in GUI.

• GPO startup script not copying files

  - by marcwenger

  I created a GPO startup script to execute for computers in a specific AD container. The script takes a file from the AD netlogon share and places it on a directory on the computer. Given the right permissions (ie: myself) can execute the script just fine and the file copies. But it doesn't work on startup - the file does not copy over from the AD server. The startup script should run as localsystem (am I right?). So the question is why do the files not copy on startup? Could it be because of: Is it permissions of the local system user? Reading the registry is problematic on startup? Obtaining files from the AD netlogon folder is problematic on startup? Am I missing it completely? My test machine does have the registry key and local directories as described in the script. I myself have standard user permissions on the test machine. AD server is Windows 2008, test client is Windows XP SP3 (and soon to be Windows 7, which I assume permissions issues will be inevitable) Dim wShell, fso, oraHome, tnsHome, key, srcDir Set wShell = WScript.CreateObject("WScript.Shell") Set fso = CreateObject("Scripting.FileSystemObject") key = "HKLM\Software\Oracle\Oracle_Home" On Error Resume Next orahome = wShell.RegRead(key) If err.Number = 0 Then tnsHome = oraHome + "\" + "network\admin\" srcDir = wShell.ExpandEnvironmentStrings("%logonserver%") + "\netlogon\UpdatedFiles\" fso.CopyFile srcDir + "file1.ext", tnsHome, true End If Side note: To ensure that the script is properly deployed, I purposely put some errors in the script, and on the next startup the error message appeared. So I know the GPO is deployed properly.

• Hearing a clicking noise from soundcard all the time

  - by Mehrdad

  I have installed Fedora 17 on my laptop. A few days ago I updated my fedora (but not upgraded). I shut down my computer and since the next time I turned it on I am hearing a clicking noise all the time from speakers. Even when I plug my headphones in I hear the noise through the headphone. I surfed over the internet and found the following shell commands: su -c 'echo "options snd_hda_intel power_save=0" /etc/modprobe.d/snd_hda_intel.conf' su -c 'echo 0 /sys/module/snd_hda_intel/parameters/power_save' I tried them but they didn't work. Here is the part of "lspci" command related to my sound-card: 00:1b.0 Audio device: Intel Corporation 82801FB/FBM/FR/FW/FRW (ICH6 Family) High Definition Audio Controller (rev 03) I have to add that my sound-card is working and I can play some audio file, I mean I can hear the voice and noise simultaneously. But everything is OK in windows xp which is also installed on my laptop. Could it be related to the sound-card driver? If so, how can I revert it to the previous version?

  - by Samuel

  I'm trying to install SQL Server from the command line through Cygwin open-ssh. The install works when I log onto the server as Administrator and execute the script through a Cygwin shell, but the install doesn't work when I SSH into the machine using Administrator's credentials and run the exact same command. I've already verified that the SSHD process is running as the Admistrator, and I've verified that the install script is indeed starting under Administrator. Is there something different with the terminal in SSH vs. the Cygwin terminal on the machine that would cause this problem? Specifically what's failing is Sql Server install runs for a while then hangs with a MSI error 1622. "Error opening installation log file. Verify that the specified log file location exists and is writable." If I run both installs, I've noticed that they have different authentication id's in ProcMon, but they have the exact same command line parameters. There has to be something in SSH that is causing permissions issues... Any ideas?

• How to setup the Mac OS X Terminal so it's *just peachy*?

  - by kch

  Hi all, My Terminal is awesome, has every detail just right (for me anyway), and now I'm setting up a few new macs around here and I have no idea whatsoever how to get their terminals to a pretty state. My user account is rather old, has been migrated over many OS X releases and machines, so my Terminal setup has grown rather organically over the years. What I need is a recipe to start from scratch, so 1) I know what I've done, and 2) I can reproduce it anywhere. Things I'm looking for: Full UTF8 support. Setting LC_*, displaying characters correctly, accepting input… I hear this got much easier in 10.5, maybe it all works out of the box now? Setup of OS X-style keyboard text navigation (option-arrows, etc) How you particularly handle meta-key support? (other than ESC'ing your way around) Other things to help our n00bs get around in the shell, such as: List of useful default key bindings (^A, ^D, etc…) Mac-specific .profile, .inputrc goodness Mac-specific tools such as pbpaste & pbcopy, Open Terminal Here, etc If at all possible, a list of files to copy over to another machine that encompasses all the changes made to tune the Terminal. (dotrc files, plists, etc) And, well, anything else really. Just keep the scope on the Mac OS X Terminal application, rather than general unix setup and tools. I think a collection of incomplete answers would be a good start. Post one or two things you remember having done, we'll vote them up, and after a few days I'll try to compile it all into a summary answer.

• Linux security: The dangers of executing malignant code as a standard user

  - by AndreasT

  Slipping some (non-root) user a piece of malignant code that he or she executes might be considered as one of the highest security breaches possible. (The only higher I can see is actually accessing the root user) What can an attacker effectively do when he/she gets a standard, (let's say a normal Ubuntu user) to execute code? Where would an attacker go from there? What would that piece of code do? Let's say that the user is not stupid enough to be lured into entering the root/sudo password into a form/program she doesn't know. Only software from trusted sources is installed. The way I see it there is not really much one could do, is there? Addition: I partially ask this because I am thinking of granting some people shell (non-root) access to my server. They should be able to have normal access to programs. I want them to be able to compile programs with gcc. So there will definitely be arbitrary code run in user-space...

• Mapped network drive missing from My Computer and Explorer

  - by matt wilkie

  On a Windows XP Pro SP3 machine one network drive refuses to show up in My Computer or Explorer. The missing drive letter is G:, if that matters. Other mappings work fine. Other profiles one the same machine have no problem mapping G:. I can access the G: just fine typing it into the address bar or in CMD shell. I've used TweakUI to toggle hide/show G: with no difference. TweakUI says G: should be visible. I've logged off,on between toggles to make sure the settings are taking effect. I've looked at reg key [HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Policies\Explorer] and made sure it's zero'd. [insert ref link here] We've limped along with this broken setup for some time, just working around it, but some applications do not allow typing in a path when choosing a place to save files and it's reached the point where it's intolerable. So, anyone have any idea why XP won't show this drive letter? or how to fix it?

• Crond offset five minute schedule

  - by sam

  Is it possible to offset a cron script set to run every 5 minutes? I have two scripts, script 1 collects some data from one database and inserts it into another, script 2 pulls out this data and a lot of other data and creates some pretty reports from it. Both scripts need to run every 5 minutes. I want to offset script 2 by one minute so that it can create a report from the new data. E.G. I want script one to run at :00, :05, :10, :15 [...] and script two to run at :01, :06, :11, :16 [...] every hour. The scripts are not dependent on each other, and script 2 must run regardless of whether script one was successful or not. But it would be useful if the reports could have hte latest data. Is this possible with cron? Post; I have thought about using both commands in a shell script so they run immediately after each other but this wouldn't work, sometimes script 1 can get hung up on waiting for external APIs etc. so might take up to 15 mins to run, but script 2 must run every 5 minutes so doing it this way would stop/delay the execution of script 2. If I could set this in Cron it would mean script 2 would run regardless of what script 1 was doing
