Tutul's questions

I want to redirect this way: from www.example.com/link.php?a=1&b=1 to www.example.net/subdirectory/link.php?a=1&b=1

I tried to use this .htaccess which isn't working:

Options +FollowSymLinks
RewriteEngine On
RewriteBase /

RewriteCond %{HTTP_HOST} ^(www\.)?example\.com$ [NC] 
RewriteRule ^(.*)$ http://www.example.net/subdirectory$ [L,R=301]

The above redirects www.example.com/link.php?a=1&b=1 to www.example.net/subdirectory/?a=1&b=1, omitting the link.php part.

System is apache2.2 + mod_rewrite running on debian wheezy 64bit. Thanks in advance.

I have added my 'example.com' to master nsd machine with records within the zone file. Now i want to setup a slave nsd machine, is it possible to transfer the zone records without adding the zone name to 'nsd.conf' in slave machine? I mean if I add a new zone name to master nsd.conf, will it be transferred to slave nsd.conf automatically?

Thanks for any help.

I inherited an LVM based centos setup where root is at an LVM partiton. I want to move my /var to a new harddisk without adding it to the LVM group. Is it possible to mount the new harddisk to /var without adding it to the LVM, like adding it to fstab directly?

I am using a custom build of exim (bundled with afterlogic pro mailsuite) with centos5.6. The system cannot send to remote mail servers like yahoo or gmail and gives this error:

[email protected] R=dnslookup defer (-1): host lookup did not complete

I can lookup gmail.com dns records with dig command:

    #dig mx gmail.com

; <<>> DiG 9.3.6-P1-RedHat-9.3.6-16.P1.el5 <<>> mx gmail.com

I'm really at a loss here , any help is appreciated.

I have a TCP service running on a PPTP client on port 4567, and the same service on another client on port 4568. They do not have public IPs. I want to connect to these services by connecting to the PPTP server on port 4567 and port 4568 from public internet. I won't be connecting as another VPN client to the PPTP server in order to access those services, any internet connected computer should be able to see those services on the PPTP server The PPTP server has a public IP. Can someone point me to any directions? Thanks in advance.

I want to setup openvpn in such a way that i can place clients in different groups and give each group a private subnet (push the addresses to clients when they connect to the openvpn server) where they are visible to each other but not to the clients on other subnets. How do i proceed?

Thanks.

I have recently installed ubuntu hardy and found that shell command completion with TAB doesn't work, the package 'bash-completion' is installed in my system. I guess it is related to dash being the default shell? Is there a way to use tab completion in dash? If there isn't a way then how can i change my default shell to bash?

I need to change the server date by running a bash script called by php. When i invoke the bash script from shell it works, but if i call it via php then it doesn't work. The bash script is run as root.

php script code:

<?php
$time = $_POST['input_time'];

$command = "/home/tutul/bin/timetest.sh";

$output=system("$command $time");
echo "$output";
?>

bash script code:

#! /bin/sh
date $1
hwclock --systohc --utc

What am i doing wrong here?

I tried to run it on my local machine when logged in as root, so i guess the script is invoked as root?

Most probably this has already been answered in other threads, but I can't find the exact solution.

I need to call a bash script via a php script which (bash) changes system time. I need to run that bash script as root while not changing apache permissions, i.e. php script called by user 'nobody' and the php script runs the script as root (sudoing is ok as I'm on ubuntu). As that will be called from a browser, I need to get rid of the password prompt
