• Prevent users from creating / copying / moving anything except .exe

  - by webnoob

  We have a program that compiles executables into a folder into c:\bin. Ideally I would like to share this folder so users can access the exe's within but stop them creating any other files in there. The reason for this is to stop users grabbing source code and putting it in a shared drive then taking it. We have a Domain Controller setup and all the users belong to a specific security group. Is there any way to achieve this? EDIT: TO clarify, I need to stop users from creating or moving files INTO the C:\bin folder which are not executables.

• problem with MySQL installation : template configuration file cannot be found

  - by user35389

  Trying to install MySQL onto the Windows XP machine. While going through the installation steps (in the "MySQL Server Instance Config. Wizard"), I get to a point where it the window reads: MySQL Server Instance Configuration (bold header) Choose the configuration for the server instance. Ready to execute... o Prepare configuration o Write configuration file o Start service o Apply security settings (this line is greyed out) Please press [Execute] to start the configuration. [ Back ] [ Execute ] [ Cancel ] So I press execute, and then a red X appears in the second step: Write configuration file and at the bottom, where it originally said: Please press [Execute] to start the configuration. It now says: The template configuration file cannot be found at C:\Program Files\MySQL\MySQL Server 5.0\bin\my-template.cnf I'm unsure what it means, but I canceled the config wizard and looked in the directory that had been created (C:\Program Files\MySQL\MySQL Server 5.0). There are some configuration settings files, and there are 4 folders: bin data Docs share

  - by Tom

  Hi, I'm having a problem with rsync. I'm on a Mac and I'd like to sync my everyday's changes from my HFS+ partition to my NTFS formated networked drive. Pretty simple, and everything goes well except that it syncs every file each times. Here's my script: #! /bin/sh snapshot_dir=/Volumes/USB_Storage/Backups snapshot_id=`date +%Y%m%d%H%M` /usr/bin/rsync -a \ --verbose \ --delete --delete-excluded \ --human-readable --progress \ --one-file-system \ --partial \ --modify-window=1 \ --exclude-from=.backup_excludes \ --link-dest ../current \ /Users/tommybergeron/Desktop/Brainpad \ $snapshot_dir/in-progress cd $snapshot_dir rm -rf $snapshot_id mv in-progress $snapshot_id rm -f current ln -s $snapshot_id $snapshot_dir/current Could someone help me out please? I've been searching for like two hours and I still am clueless. Thanks so much.

• cygWin connect by SSH using RSA key; ssh.exe couldn't create /home/user/.ssh

  - by Kirzilla

  I'm using Win XP and I'm trying to connect by SSH to remote host using RSA key. I've investigated that cygWin recognizes Documents and Settings dir as home directory Z:\app\cwRsync\bin>cygpath -H /cygdrive/c/Documents and Settings I've created .ssh directory in Documents and Settings/user/.ssh and moved known_hosts, id_rsa, id_rsa.pub there. Now, I'm trying to connect via ssh.exe to remote host Z:\app\cwRsync\bin>ssh -p 22 [email protected] Could not create directory '/home/user/.ssh'. The authenticity of host '[remotehost.com]:22 ([remotehost.com]:22)' can't be established. RSA key fingerprint is f7:f4:2c:e0:c6:7e:d2:a4:45:70:63:df:bf:f2:84:46. Are you sure you want to continue connecting (yes/no)? What I'm doing wrong? Why ssh.exe couldn't create directory /home/user/.ssh? Thank you.

• Can you specify git-shell in .ssh/authorized_keys to restrict access to only git commands via ssh?

  - by Matt Connolly

  I'd like to be able to use a ssh key for authentication, but still restrict the commands that can be executed over the ssh tunnel. With Subversion, I've achieved this by using a .ssh/authorized_keys file like: command="/usr/local/bin/svnserve -t --tunnel-user matt -r /path/to/repository",no-port-forwarding,no-agent-forwarding,no-X11-forwarding,no-pty ssh-rsa AAAAB3NzaC1yc2EAAAABIetc... I've tried this with "/usr/bin/git-shell" in the command, but I just get the funky old fatal: What do you think I am? A shell? error message.

• Add user in CentOS 5

• Xdebug 2.0.5 with Zend Server CE PHP5.2.12 possible?

  - by notbrain

  I'm using Zend Server CE with PHP 5.2.12 on OSX Snow Leopard and want to use Xdebug. I've turned off Zend Data Cache, Zend Optimizer+, and Zend Debugger in the console. When I run $ cd ~/Downloads/xdebug-2.0.5 $ /usr/local/zend/bin/phpize I get Configuring for: PHP Api Version: 20041225 Zend Module Api No: 20060613 Zend Extension Api No: 220060519 The PHP API Version, 20041225, seems to be off from the documentation (aka wrong). When I continue installation with $ ./configure ---with-php-config=/usr/local/zend/bin/php-config $ make $ sudo make install The installed xdebug.so seems to be the wrong one. Which version of xdebug do I need for this PHP API version? The Zend API numbers are ok. I'm just confused at why the PHP API Version doesn't match.

• How to make Ubuntu useradd behave like Centos useradd?

  - by Buttle Butkus

  I don't remember modifying CentOS useradd to get this behavior. useradd in CentOS creates the user's home directory with all the normal files (like .bashrc). I modified /etc/default/useradd to make it looks like CentOS (just required some uncommenting) except for Ubuntu having SHELL=/bin/sh instead of SHELL=/bin/bash How do I make useradd act like it does in CentOS? Is there some existing option to change? Or should I just add an alias to /etc/bash.bashrc? The difference: On Ubuntu, useradd is not creating the home directory. as root: $ useradd test $ cd ~test -su: cd: /home/test: No such file or directory

• Scanning php uploads in tmp directory with clamdscan fails

  - by Nikola

  I can't seem to get this thing to work, some permission problem maybe, but i can't even run clamdscan normally form console with root the result is always Permission denied. for example i create a file test.txt (eicar file) in /tmp and execute "clandscan /tmp/test.txt" in console logged in as root and i get "/tmp/test.txt: Access denied. ERROR ". The clamd demon is running with user clamav could that be the reason? Now i want to scan the same file (/tmp/test.txt) via php , so i run (i have chowned the file to apache:apache ) $cmd="clamdscan /tmp/test.txt"; exec($cmd,$a,$b); i get error 127 i try with the full path of the command /usr/bin/clamdscan i get error 126 (command is found but is not executable), this means that apache doesn't have the permission to execute /usr/bin/clamdscan ? what could be the problem?

• "killed" message from cron.daily, but not when run from command line

  - by Dan Stahlke

  On Fedora 17, I put a file into /etc/cron.daily with the following contents: cd / su dstahlke /home/dstahlke/bin/anacron-daily.sh exit 0 For some reason, I get a mail every day that just says /etc/cron.daily/dstahlke-daily: ...killed. I tried with and without the exit 0 line above (I noticed that some system scripts have that and others don't, I'm not sure of the purpose). Running /etc/cron.daily/dstahlke-daily from the command line as root produces no ...killed message. Other than the message, everything seems to work fine. Putting set -x in the above script, as well as in the /home/dstahlke/bin/anacron-daily.sh script shows that the ...killed message happens just after the latter script terminates (or perhaps just after the su command finishes). What causes the ...killed message? Or, is there a more acceptable way to have anacron run a user script daily? I figured that putting this in /etc/cron.daily would help the system coordinate all of the daily tasks rather than potentially running my task concurrently with the system tasks.

• How come Win+R prompt can open Python when it's not in my path?

  - by houbysoft

  When I use the run prompt in Windows XP Professional (Win+R), and type python.exe or python, it works and greets me with the python prompt. However, when I start a cmd window, and then type python.exe or python, it doesn't find it. This is what I expect, as the Python directory (for me, I:\Python31\) is not in my PATH. How come, then, that if I type python.exe in the Win+R prompt, it works? Edit: here is a partial output of SET, I removed most irrelevant entries, I'm not sure why is it useful, apart from the PATH variable which I already said doesn't include the Python directory. If you need a particular variable other than these, please ask. CLIENTNAME=Console CommonProgramFiles=I:\Program Files\Common Files ComSpec=I:\WINDOWS\system32\cmd.exe FP_NO_HOST_CHECK=NO OS=Windows_NT Path=I:\WINDOWS\system32;I:\WINDOWS;I:\WINDOWS\system32\WBEM;I:\WINDOWS\system32\WindowsPowerShell\v1.0;I:\Qt\2010.05\mingw\bin;I:\Program Files\CMake 2.8\bin PATHEXT=.COM;.EXE;.BAT;.CMD;.VBS;.VBE;.JS;.JSE;.WSF;.WSH;.PSC1 ProgramFiles=I:\Program Files PROMPT=$P$G SESSIONNAME=Console SystemDrive=I: SystemRoot=I:\WINDOWS VBOX_INSTALL_PATH=I:\Program Files\Oracle\VirtualBox\ windir=I:\WINDOWS

• Change/Deactivate the shell for an amount of users on SUSE Enterprise Server

  - by Manfred Schmidt

  I have a SUSE Server to which ~300 users are connecting. About 100 of them have to be deactivated. I think it would be nice to change their shell to /bin/false either with chsh or with usermod. Do I have to type every command per line, or can I fill out a list of users which can be read from the script? I should mention that all of the 100 users have the same ending in their username. Can I work with wildcards here? e.g. usermod -s /bin/fish *ftpuser chsh -s /sbin/nologin *ftpuser

• Why do I sometimes get 'sh: $'\302\211 ... ': command not found' in xterm/sh?

  - by amn

  Sometimes when I simply type a valid command like 'find ...', or anything really, I get back the following, which is completely unexpected and confusing (... is command name I type): sh: $'\302\211...': command not found There is some corruption going on I think. I don't use color in my prompt, I am using the Bash shell in POSIX mode as sh (chsh to /bin/sh and so on - $SHELL is sh). What is going on and why does this keep happening? Anything I can debug? I think this is more of an xterm issue than sh, or at least a combination of the two. Files, for context: My /etc/profile, as distributed with Arch Linux x86-64: # /etc/profile #Set our umask umask 022 # Set our default path PATH="/usr/local/sbin:/usr/local/bin:/usr/bin" export PATH # Load profiles from /etc/profile.d if test -d /etc/profile.d/; then for profile in /etc/profile.d/*.sh; do test -r "$profile" && . "$profile" done unset profile fi # Source global bash config if test "$PS1" && test "$BASH" && test -r /etc/bash.bashrc; then . /etc/bash.bashrc fi # Termcap is outdated, old, and crusty, kill it. unset TERMCAP # Man is much better than us at figuring this out unset MANPATH My /etc/shrc, which I created as a way to have sh parse some file on startup, when non-login shell. This is achieved using ENV variable set in /etc/environment with the line ENV=/etc/shrc: PS1='\u@\H \w \$ ' alias ls='ls -F --color' alias grep='grep -i --color' [ -f ~/.shrc ] && . ~/.shrc My ~/.profile, I am launching X when logging in through first virtual tty: [[ -z $DISPLAY && $XDG_VTNR -eq 1 ]] && exec xinit -- -dpi 111 My ~/.xinitc, as you can see I am using the system as a Virtual Box guest: xrdb -merge ~/.Xresources VBoxClient-all awesome & exec xterm And finally, my ~/.Xresources, no fancy stuff here I guess: *faceName: Inconsolata *faceSize: 10 xterm*VT100*translations: #override <Btn1Up>: select-end(PRIMARY, CLIPBOARD, CUT_BUFFER0) xterm*colorBDMode: true xterm*colorBD: #ff8000 xterm*cursorColor: S_red Since ~/.profile references among other things /etc/bash.bashrc, here is its content: # # /etc/bash.bashrc # # If not running interactively, don't do anything [[ $- != *i* ]] && return PS1='[\u@\h \W]\$ ' PS2='> ' PS3='> ' PS4='+ ' case ${TERM} in xterm*|rxvt*|Eterm|aterm|kterm|gnome*) PROMPT_COMMAND=${PROMPT_COMMAND:+$PROMPT_COMMAND; }'printf "\033]0;%s@%s:%s\007" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"' ;; screen) PROMPT_COMMAND=${PROMPT_COMMAND:+$PROMPT_COMMAND; }'printf "\033_%s@%s:%s\033\\" "${USER}" "${HOSTNAME%%.*}" "${PWD/#$HOME/~}"' ;; esac [ -r /usr/share/bash-completion/bash_completion ] && . /usr/share/bash-completion/bash_completion I have no idea what that case statement does, by the way, it does look a bit suspicious though, but then again, who am I to know.

• connection to apache server switches sockets connection

  - by Newben

  I have just post a question but I post an other one because the problem is not the one I had in thought when asking the latter. So, I am running some rails app on osx, when I run rails s, everything works fine. If I shut down the apache server (mamp) and if I run rails s again, I have this message Can't connect to local MySQL server through socket '/Applications/MAMP/tmp/mysql/mysql.sock', which for sure is normal. For info, my mamp server is running, and the connection must pass through /Applications/MAMP/Library/bin/mysql, so I aliased it by setting in my bash profile : alias mysql="/Applications/MAMP/Library/bin/mysql" Now, when I launch a rails generate command type, I get this message : /$root/vendor/bundle/ruby/2.0.0/gems/mysql2-0.3.11/lib/mysql2/client.rb:44:in `connect': Can't connect to local MySQL server through socket '/tmp/mysql.sock' (2) (Mysql2::Error) So how it can be ?

• change browser to open weblinks in thunderbird

  - by Bevor

  Hello, because it's almost obvious that either Thunderbird or Firefox freeze my whole system after some time, I'd like to not use FF at the moment and let Thunderbird run only for a short time as long as I check e-mails. Thunderbird web links should be opened with opera from now. For that I went in Thunderbird to Preferences-Advanced-General-Config Editor and set the following: network.protocol-handler.app.http -> /usr/bin/opera network.protocol-handler.app.https -> /usr/bin/opera network.protocol-handler.warn-external.ftp -> true network.protocol-handler.warn-external.http -> true network.protocol-handler.warn-external.https -> true Moreover I changed in Gnome in System-Preferences-Prefered Applications Opera as webbrowser and I checked in FF that it should warn if FF is not the default browser (obviously it isn't anymore). Unfortunately all of these settings doesn't work. Thunderbird still opens web links with FF. Any explantions why? (I already restarted Thunderbird although I don't have to, but no effect)

• Plesk 9 - unable to modify atmail vhost template

  - by Ben

  Running into a small issue recently that causes my server's atmail to fail authenticating users. I gathered from a web search that it's because i recently enabled apc on the server. I've found some reference mentioning I need to modify the atmail vhost template, but that reference is for Plesk 10 (i'm on 9). The atmail config isn't in the same spot. I've found this unrelated topic that explains how to modify the vhost settings for atmail on plesk 9, which I have done (adding php_admin_flag apc.enabled off to it). I then recompiled the server config using /usr/local/psa/admin/bin/websrvmng -a but it doesn't seem to pick up the changes. If I look at /etc/httpd/conf.d/zzz_atmail_vhost.conf after recompiling it still doesn't show the apc settings. Summary of steps taken: Modified /etc/psa-webmail/atmail/atmail_vhost.conf and added php_admin_flag register_globals off to the config Recompiled with /usr/local/psa/admin/bin/websrvmng -a Checked /etc/httpd/conf.d/zzz_atmail_vhost.conf But no changes. What am I missing?

• System user authentication via web interface [closed]

  - by donodarazao

  Background: We have one pretty slow and expensive satellite Internet connection that is shared in a network with 5-50 users. To limit traffic, users shall pay a certain sum of money per hour. Routing and traffic accounting on user basis is done by a opensuse 10.3 server. Login is done via pppoe, and for each connection, username, bytes_sent, bytes_rcvd, start_time, end_time,etc are written into a mysql database. Now it was decided that we want to change from time-based to volume-based pricing. As the original developer who installed the system a couple of years ago isn't available, I'm trying to do the changes. Although I'm absolutely new to all this, there is some progress. However, there's one point I'm absolutely stuck. Up to now, only administrators can access connection details and billing information via a web interface. But as volume-based prices are less transparent to users than time-based prices, it is essential that users themselves can check their connections and how much they cost via the web interface. For this, we need some kind of user authentication. Actual question: How to develop such a user authentication? Every user has a linux system user account. With this user name and password, connection to the pppoe-server is made by the client machines. I thought about two possibles ways to authenticate users: First possibility: Users type username and password in a form. This is then somehow checked. We already have to possibilities to change passwords via the web interface. Here are parts of the code: Part of the Perl script the homepage is linked to: #!/usr/bin/perl use CGI; use CGI::Carp qw(fatalsToBrowser); use lib '../lib'; use own_perl_module; my @error; my $data; $query = new CGI; $username = $query->param('username') || ''; $oldpasswd = $query->param('oldpasswd') || ''; $passwd = $query->param('passwd') || ''; $passwd2 = $query->param('passwd2') || ''; own_perl_module::connect(); if ($query->param('submit')) { my $benutzer = own_perl_module::select_benutzer(username => $username) or push @error, "user not exists"; push @error, "your password?!?" unless $passwd; unless (@error) { own_perl_module::update_benutzer($benutzer->{id}, { oldpasswd => $oldpasswd, passwd => $passwd, passwd2 => $passwd2 }, error => \@error) and push @error, "Password changed."; } } Here's part of the sub update_benutzer in the own_perl_module: if ($dat-{passwd} ne '') { my $username = $dat-{username} || $select-{username}; my $system = "./chpasswd.pl '$username' '$dat-{passwd}'" . (defined($dat-{oldpasswd}) ? " '$dat-{oldpasswd}'" : undef); my $answer = $system; if ($? != 0) { chomp($answer); push @$error, $answer || "error changing password ($?)"; Here's chpasswd.pl: #!/usr/bin/perl use FileHandle; use IPC::Open3; local $username = shift; local $passwd = shift; local $oldpasswd = shift; local $chat = { 'Old Password: $' => sub { print POUT "$oldpasswd\n"; }, 'New password: $' => sub { print POUT "$passwd\n"; }, 'Re-enter new password: $' => sub { print POUT "$passwd\n"; }, '(.*)\n$' => sub { print "$1\n"; exit 1; } }; local $/ = \1; my $command; if (defined($oldpasswd)) { $command = "sudo -u '$username' /usr/bin/passwd"; } else { $command = "sudo /usr/bin/passwd '$username'"; } $pid = open3(\*POUT, \*PIN, \*PERR, $command) or die; my $buffer; LOOP: while($_ = <PERR>) { $buffer .= $_; foreach (keys(%$chat)) { if ($buffer =~ /$_/i) { $buffer = undef; &{$chat->{$_}}; } } } exit; Could this somehow be adjusted to verify users, but not changing user passwords? The second possibility I see: all pppoe connections are logged in the mysql database. If I could somehow retrieve the username (or uid) of the user connected by pppoe, this could be used to authenticate users. Users could only check their internet connections and costs when they are online (and thus paying money), but this could be tolerated. Here's a line of the script that inserts connections into the database: my $username = $ENV{PEERNAME}; I thought it would be easy to use this variable, but $username seems to be always empty in test-scripts (print $username). Any idea how to retrieve the user connected to the pppoe server? Sorry for the long question! Any help would be very much appreciated. :)

• HTTPS in sub domain redirects to main domain

  - by Amitabh

  We recently bought a wildcard certificate and installed it for a domain. It works fine for the main domain but seems to not work at all for any sub domains. Whats happening is we can access the sub domains fine on HTTP, but whenever we try HTTPS for the same sub domain url we are redirected back to the main domain. So if I put up a test folder "httpstest" in a sub domain with a index.html file in it, the following happens mysubdomain.mywebsite.com/httpstest/index.html or mysubdomain.mywebsite.com/httpstest/ works perfectly fine with http:// but mysubdomain.mywebsite.com/httpstest/ or mysubdomain.mywebsite.com/httpstest/index.html does not work with https:// and redirects to the main domain.Any help on this is greatly appreciated. The site is not the main site used for setting up the VPS. It was added from WHM. Environment: We are on a Linux VPS. Cpanel 11.30.6 , Apache 2.2.22, PHP 5.3.13 The Virtualhost entry looks like: <VirtualHost xx.xx.xxx.xx:443> ServerName my-own-website.com ServerAlias www.my-own-website.com DocumentRoot /home/amitabh/public_html ServerAdmin [email protected] UseCanonicalName Off CustomLog /usr/local/apache/domlogs/my-own-website.com combined CustomLog /usr/local/apache/domlogs/my-own-website.com-bytes_log "%{%s}t %I .\n%{%s}t %O ." ## User amitabh # Needed for Cpanel::ApacheConf <IfModule mod_suphp.c> suPHP_UserGroup amitabh amitabh </IfModule> <IfModule !mod_disable_suexec.c> SuexecUserGroup amitabh amitabh </IfModule> ScriptAlias /cgi-bin/ /home/amitabh/public_html/cgi-bin/ SSLEngine on SSLCertificateFile /etc/ssl/certs/my-own-website.com.crt SSLCertificateKeyFile /etc/ssl/private/my-own-website.com.key SSLCACertificateFile /etc/ssl/certs/my-own-website.com.cabundle CustomLog /usr/local/apache/domlogs/my-own-website.com-ssl_log combined SetEnvIf User-Agent ".*MSIE.*" nokeepalive ssl-unclean-shutdown <Directory "/home/amitabh/public_html/cgi-bin"> SSLOptions +StdEnvVars </Directory> # To customize this VirtualHost use an include file at the following location # Include "/usr/local/apache/conf/userdata/ssl/2/amitabh/my-own-website.com/*.conf" </VirtualHost>` I guess I messed up the formatting big time. Any help on formatting and on the issue is great appreciated. Thank you. Update: I could not update the formatting here. I posted the same question in a linux forum . I will really appreciate any pointer on it.

• How can I make a persistent ssh tunnel?

  - by Blacklight Shining

  I have a Mac laptop and would like to have a persistent ssh tunnel so I can always log in from outside the local network. I'm looking for something that will work when the server can't be reached initially (e.g. if I don't have an Internet connection when I boot it), and will automatically start the tunnel when possible. I've tried putting an @reboot autossh line in my crontab, but I've found that sessions started with autossh disconnect every so often, and autossh quits if the first attempt fails. My current workaround is a small script and a cronjob: # crontab /home/blackl/bin/script &! # script #!/bin/sh while true; do ssh -Ngn -R $some_port:localhost:22 $server; sleep 30; done; Is there a better way to do this, or will I just have to be happy with this for now?

• Entire filesystem restore from rdiff-backup snapshot

  - by atmosx

  I'm trying to make a complete system restore from an rdiff-backup. The cli for backing was: rdiff-backup --exclude-special-files --exclude /tmp --exclude /mnt --exclude /proc --exclude /sys / /mnt/backup/ebox/ I created a new partition mounted the partition at /mnt/gentoo and did: rdiff-backup -r /mnt/vol2 /mnt/gentoo However when I try to chroot to this system (following gentoo's manual, which means mounting /dev/ and /proc) I get the following error: chroot: failed to run command/bin/bash': No such file or directory` All this takes place on a Parallels (virtual machine) Debian installation. Any ideas on how to proceed in order to fully restore the system? Best Regards ps. /mnt/gentoo/bin/bash works fine if I execute it. All files and permissions are in place rdiff-backup seems to work just fine. However the system cannot neither boot (exits with kernel panic - cannot find init) or be chrooted.
